Clinical Pharmacology for Opdivo Qvantig
Mechanism Of Action
Binding of the PD-1 ligands, PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T-cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors. Nivolumab is a human immunoglobulin G4 (IgG4) monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response. In syngeneic mouse tumor models, blocking PD-1 activity resulted in decreased tumor growth.
Hyaluronan is a polysaccharide found in the extracellular matrix of the subcutaneous tissue. It is depolymerized by the naturally occurring enzyme hyaluronidase. Unlike the stable structural components of the interstitial matrix, hyaluronan has a half-life of approximately 0.5 days. Hyaluronidase increases permeability of the subcutaneous tissue by temporarily depolymerizing hyaluronan. In the doses administered, hyaluronidase in OPDIVO QVANTIG acts transiently and locally. The effects of hyaluronidase are reversible and permeability of the subcutaneous tissue is restored within 24 to 48 hours.
Pharmacodynamics
Exposure-Response Relationship
The exposure-response relationship and time course of pharmacodynamics of OPDIVO QVANTIG have not been fully characterized.
Pharmacokinetics
When comparing nivolumab exposures following OPDIVO QVANTIG to those of intravenous nivolumab in CHECKMATE-67T [see Clinical Studies], the geometric mean ratios (GMRs) (90% CI) for time-averaged concentration (Cavg) over 28 days and at steady state were 2.10 (2.00, 2.20) and 1.98 (1.87, 2.11), respectively, and for minimum concentration (Cmin) at 28 days and at steady state were 1.60 (1.49, 1.72) and 1.77 (1.63, 1.93), respectively.
Steady state was achieved by 16 weeks. The systemic accumulation ratio was 2.3.
Absorption
The geometric mean bioavailability (CV%) of nivolumab is 74% (14%). Peak concentrations occurred by around 6 days.
Distribution
The geometric mean (CV%) volume of distribution at steady state is 6.8 L (27%).
Elimination
Nivolumab clearance decreases over time, with a mean maximal reduction (CV%) from baseline values of 24.5% (47.6%), resulting in a geometric mean steady-state clearance (CV%) of 8.2 mL/h (53.9%) in patients with metastatic tumors; this decrease in clearance is not considered clinically relevant. Nivolumab clearance does not decrease over time in patients with completely resected melanoma, as the geometric mean population clearance is 24% lower in this patient population compared with patients with metastatic melanoma at steady state.
The geometric mean (CV%) elimination half-life is 25 days (78%).
Specific Populations
Body weight (35 to 153 kg), sex, eGFR (24 to 124 mL/min/1.73 m2), and performance status have no clinically significant effects on the clearance of nivolumab.
Immunogenicity
The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of OPDIVO QVANTIG or of other nivolumab products or hyaluronidase products.
During the 2-year treatment period in CHECKMATE-67T [see Clinical Studies], 23% (46/202) of patients who received OPDIVO QVANTIG developed anti-nivolumab antibodies (ADA) and 4.3% (2/46) had neutralizing antibodies against nivolumab (NAb). The corresponding incidence of ADA was 7% (15/215) and NAb was 0% (0/15) for intravenous nivolumab in the same study. The incidence of anti-hyaluronidase antibodies in CHECKMATE-67T was 8.8% (19/215); 5 (26%) of these 19 patients developed NAb.
Nivolumab clearance increased by approximately 26% in patients who received OPDIVO QVANTIG and tested positive for ADA compared to patients who tested negative for ADA; this change in clearance is not considered clinically significant. Local injection-site reactions were reported in 15% (7/46) of patients who developed ADA to nivolumab and 7% (10/155) of patients who did not develop ADA to nivolumab; however, all events were Grade 1 or 2 and resolved. Because of low occurrence of anti-nivolumab or anti-hyaluronidase antibodies, the effect of ADA on the effectiveness of OPDIVO QVANTIG is unknown.
Animal Toxicology And/Or Pharmacology
In animal models, inhibition of PD-1 signaling increased the severity of some infections and enhanced inflammatory responses. Mycobacterium tuberculosis–infected PD-1 knockout mice exhibit markedly decreased survival compared with wild-type controls, which correlated with increased bacterial proliferation and inflammatory responses in these animals. PD-1 blockade using a primate anti–PD-1 antibody was also shown to exacerbate M. tuberculosis infection in rhesus macaques. PD-1 knockout mice have also shown decreased survival following infection with lymphocytic choriomeningitis virus.
Clinical Studies
Advanced Renal Cell Carcinoma
Previously Treated Renal Cell Carcinoma – OPDIVO QVANTIG
The efficacy of OPDIVO QVANTIG was evaluated in CHECKMATE-67T (NCT04810078), a multicenter, randomized, open-label study in patients with advanced or metastatic clear cell renal cell carcinoma. Patients 18 years of age or older with histologically confirmed advanced or metastatic renal cell carcinoma with a clear cell component, including those with sarcomatoid features, and who received no more than 2 prior systemic treatment regimens were randomized to receive OPDIVO QVANTIG (containing 1,200 mg of nivolumab and 20,000 units of hyaluronidase) every 4 weeks subcutaneously, or nivolumab 3 mg/kg every 2 weeks intravenously. Patients with untreated, symptomatic central nervous system (CNS) metastases; leptomeningeal metastases; concurrent malignancies requiring treatment or history of prior malignancy within the previous 2 years; active, known, or suspected autoimmune disease; or who received prior treatment with a checkpoint inhibitor were excluded from the study. Patients with asymptomatic, stable CNS metastases that did not require immediate treatment were eligible if there was no evidence of progression within 28 days prior to the first dose of study drug administration. Stratification factors for randomization were weight (<80 kg vs ≥80 kg) and International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk classification (favorable vs intermediate, vs poor risk). The primary objective was to assess the nivolumab exposure of subcutaneous administration of OPDIVO QVANTIG as compared to the intravenous administration of nivolumab. The secondary objective of the study was to evaluate overall response rate (ORR) by blinded independent central review (BICR).
A total of 495 patients were randomized to receive either OPDIVO QVANTIG (n=248) or intravenous nivolumab (n=247). The median age was 65 years (range: 20 to 93), with 51% ≥65 years of age and 14% ≥75 years of age; 68% male; 85% White, 12.5% not reported, 1% American Indian or Alaska Native, 0.8% Asian, and 0.4% Black; 36% Hispanic or Latino, 33% not Hispanic or Latino, and 31% not reported. Fifty-seven percent of patients weighed <80 kg and 43% weighed ≥80 kg. Baseline Karnofsky performance status was 70 (7%), 80 (20%), 90 (34%), or 100 (39%). Patient distribution by IMDC risk categories was 21% favorable, 62% intermediate, and 17% poor.
When comparing subcutaneous administration of OPDIVO QVANTIG to the intravenous administration of nivolumab, CHECKMATE-67T met the predefined acceptance margin for pharmacokinetic endpoints, with the lower boundary of 90% confidence interval of geometric mean ratios of not less than 0.8 for both serum nivolumab Cavg over 28 days and Cmin at steady state. [see CLINICAL PHARMACOLOGY]. Efficacy results are shown in Table 45.

RCC Trials -Intravenous Nivolumab
The effectiveness of OPDIVO QVANTIG has been established for the following:
- as monotherapy, for advanced renal cell carcinoma (RCC) following treatment with intravenous nivolumab and ipilimumab combination therapy (CHECKMATE-214 study).
- in combination with cabozantinib, for the first-line treatment of adult patients with advanced RCC (CHECKMATE-9ER study).
- as monotherapy, for the treatment of adult patients with advanced RCC who have received prior anti-angiogenic therapy (CHECKMATE-025 study).
Use of OPDIVO QVANTIG for these RCC indications is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab in the CHECKMATE-67T trial [see ADVERSE REACTIONS, CLINICAL PHARMACOLOGY and Clinical Studies]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous nivolumab in these RCC populations.
First-Line Renal Cell Carcinoma
CHECKMATE-214
CHECKMATE-214 (NCT02231749) was a randomized (1:1), open-label trial in patients with previously untreated advanced RCC. Patients were included regardless of their PD-L1 status. CHECKMATE-214 excluded patients with any history of or concurrent brain metastases, active autoimmune disease, or medical conditions requiring systemic immunosuppression. Patients were stratified by International Metastatic RCC Database Consortium (IMDC) prognostic score and region.
Efficacy was evaluated in intermediate/poor risk patients with at least 1 or more of 6 prognostic risk factors as per the IMDC criteria (less than one year from time of initial renal cell carcinoma diagnosis to randomization, Karnofsky performance status <80%, hemoglobin less than the lower limit of normal, corrected calcium of >10 mg/dL, platelet count greater than the upper limit of normal, and absolute neutrophil count greater than the upper limit of normal).
Patients were randomized to nivolumab 3 mg/kg and ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses followed by nivolumab 3 mg/kg intravenously every two weeks (n=425), or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (n=422). Treatment continued until disease progression or unacceptable toxicity.
The trial population characteristics were: median age was 61 years (range: 21 to 85) with 38% ≥65 years of age and 8% ≥75 years of age. The majority of patients were male (73%) and White (87%) and 26% and 74% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively.
The major efficacy outcome measures were OS, PFS (independent radiographic review committee [IRRC]-assessed) and confirmed ORR (IRRC-assessed) in intermediate/poor risk patients. In this population, the trial demonstrated statistically significant improvement in OS and ORR for patients randomized to intravenous nivolumab and ipilimumab as compared with sunitinib (Table 46 and Figure 1). OS benefit was observed regardless of PD-L1 expression level. The trial did not demonstrate a statistically significant improvement in PFS. Efficacy results are shown in Table 46 and Figure 1.

CHECKMATE-214 also randomized 249 favorable risk patients as per IMDC criteria to intravenous nivolumab and ipilimumab (n=125) or to sunitinib (n=124). These patients were not evaluated as part of the efficacy analysis population. OS in favorable risk patients receiving intravenous nivolumab and ipilimumab compared to sunitinib has a hazard ratio of 1.45 (95% CI: 0.75, 2.81). The efficacy of intravenous nivolumab and ipilimumab in previously untreated renal cell carcinoma with favorable-risk disease has not been established.
CHECKMATE-9ER
CHECKMATE-9ER (NCT03141177) was a randomized, open-label study of intravenous nivolumab combined with cabozantinib versus sunitinib in patients with previously untreated advanced RCC. CHECKMATE-9ER excluded patients with autoimmune disease or other medical conditions requiring systemic immunosuppression. Patients were stratified by IMDC prognostic score (favorable vs. intermediate vs. poor), PD-L1 tumor expression (≥1% vs. <1% or indeterminate), and region (US/Canada/Western Europe/Northern Europe vs. Rest of World).
Patients were randomized to nivolumab 240 mg intravenously every 2 weeks and cabozantinib 40 mg orally daily (n=323), or sunitinib 50 mg orally daily for the first 4 weeks of a 6-week cycle (4 weeks on treatment followed by 2 weeks off) (n=328). Treatment continued until disease progression per RECIST v1.1 or unacceptable toxicity. Treatment beyond RECIST-defined disease progression was permitted if the patient was clinically stable and considered to be deriving clinical benefit by the investigator. Tumor assessments were performed at baseline, after randomization at Week 12, then every 6 weeks until Week 60, and then every 12 weeks thereafter.
The trial population characteristics were: median age 61 years (range: 28 to 90) with 38% ≥65 years of age and 10% ≥75 years of age. The majority of patients were male (74%) and White (82%) and 23% and 77% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively. Patient distribution by IMDC risk categories was 22% favorable, 58% intermediate, and 20% poor.
The major efficacy outcome measure was PFS (BICR assessed). Additional efficacy outcome measures were OS and ORR (BICR assessed). The trial demonstrated a statistically significant improvement in PFS, OS, and ORR for patients randomized to intravenous nivolumab and cabozantinib compared with sunitinib. Consistent results for PFS were observed across prespecified subgroups of IMDC risk categories and PD-L1 tumor expression status. An updated OS analysis was conducted when 271 deaths were observed based on the pre-specified number of deaths for the pre-planned final analysis of OS. Efficacy results are shown in Table 47 and Figures 2 and 3.

Previously Treated Renal Cell Carcinoma
CHECKMATE-025
CHECKMATE-025 (NCT01668784) was a randomized (1:1), open-label trial in patients with advanced RCC who had experienced disease progression during or after one or two prior antiangiogenic therapy regimens. Patients had to have a Karnofsky Performance Score (KPS) ≥70% and patients were included regardless of their PD-L1 status. The trial excluded patients with any history of or concurrent brain metastases, prior treatment with an mTOR inhibitor, active autoimmune disease, or medical conditions requiring systemic immunosuppression. Patients were stratified by region, Memorial Sloan Kettering Cancer Center (MSKCC) Risk Group and the number of prior anti-angiogenic therapies. Patients were randomized to nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=410) or everolimus 10 mg orally daily (n=411). The first tumor assessments were conducted 8 weeks after randomization and continued every 8 weeks thereafter for the first year and then every 12 weeks until progression or treatment discontinuation, whichever occurred later. The major efficacy outcome measure was overall survival (OS).
The trial population characteristics were: median age was 62 years (range: 18 to 88) with 40% ≥65 years of age and 9% ≥75 years of age. The majority of patients were male (75%) and White (88%) and 34% and 66% of patients had a baseline KPS of 70% to 80% and 90% to 100%, respectively. The majority of patients (77%) were treated with one prior anti-angiogenic therapy. Patient distribution by MSKCC risk groups was 34% favorable, 47% intermediate, and 19% poor.
The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with everolimus at the prespecified interim analysis when 398 events were observed (70% of the planned number of events for final analysis). OS benefit was observed regardless of PD-L1 expression level. Efficacy results are shown in Table 48 and Figure 4.

Unresectable Or Metastatic Melanoma
Previously Treated Metastatic Melanoma
The effectiveness of OPDIVO QVANTIG has been established for the treatment of previously treated unresectable or metastatic melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of this adequate and well-controlled study of intravenous nivolumab in this melanoma population.
OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.
CHECKMATE-037
CHECKMATE-037 (NCT01721746) was a multicenter, open-label trial that randomized (2:1) patients with unresectable or metastatic melanoma to receive nivolumab 3 mg/kg intravenously every 2 weeks or investigator’s choice of chemotherapy, either single-agent dacarbazine 1000 mg/m2 every 3 weeks or the combination of carboplatin AUC 6 intravenously every 3 weeks and paclitaxel 175 mg/m2 intravenously every 3 weeks. Patients were required to have progression of disease on or following ipilimumab treatment and, if BRAF V600 mutation positive, a BRAF inhibitor. The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, ocular melanoma, active brain metastasis, or a history of Grade 4 ipilimumab-related adverse reactions (except for endocrinopathies) or Grade 3 ipilimumab-related adverse reactions that had not resolved or were inadequately controlled within 12 weeks of the initiating event. Tumor assessments were conducted 9 weeks after randomization then every 6 weeks for the first year, and every 12 weeks thereafter.
Efficacy was evaluated in a single-arm, non-comparative, planned interim analysis of the first 120 patients who received intravenous nivolumab in CHECKMATE-037 and in whom the minimum duration of follow-up was 6 months. The major efficacy outcome measures in this population were confirmed overall response rate (ORR) as measured by blinded independent central review using Response Evaluation Criteria in Solid Tumors (RECIST 1.1) and duration of response.
Among the 120 patients treated with intravenous nivolumab, the median age was 58 years (range: 25 to 88), 65% of patients were male, 98% were White, and the ECOG performance score was 0 (58%) or 1 (42%). Disease characteristics were M1c disease (76%), BRAF V600 mutation positive (22%), elevated LDH (56%), history of brain metastases (18%), and two or more prior systemic therapies for metastatic disease (68%).
The ORR was 32% (95% confidence interval [CI]: 23, 41), consisting of 4 complete responses and 34 partial responses in intravenous nivolumab-treated patients. Of 38 patients with responses, 87% had ongoing responses with durations ranging from 2.6+ to 10+ months, which included 13 patients with ongoing responses of 6 months or longer. There were responses in patients with and without BRAF V600 mutation-positive melanoma. A total of 405 patients were randomized and the median duration of OS was 15.7 months (95% CI: 12.9, 19.9) in nivolumab-treated patients compared to 14.4 months (95% CI: 11.7, 18.2) (HR 0.95; 95.54% CI: 0.73, 1.24) in patients assigned to investigator’s choice of treatment. Figure 5 summarizes the OS results.

Previously Untreated Metastatic Melanoma
The effectiveness of OPDIVO QVANTIG has been established for the treatment of previously untreated unresectable or metastatic melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous nivolumab in this melanoma population.
OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.
CHECKMATE-066
CHECKMATE-066 (NCT01721772) was a multicenter, double-blind, randomized (1:1) trial in 418 patients with BRAF V600 wild-type unresectable or metastatic melanoma. Patients were randomized to receive either nivolumab 3 mg/kg by intravenous infusion every 2 weeks or dacarbazine 1000 mg/m2 intravenously every 3 weeks until disease progression or unacceptable toxicity. Randomization was stratified by PD-L1 status (≥5% of tumor cell membrane staining by immunohistochemistry vs. <5% or indeterminate result) and M stage (M0/M1a/M1b versus M1c). Key eligibility criteria included histologically confirmed, unresectable or metastatic, cutaneous, mucosal, or acral melanoma; no prior therapy for metastatic disease; completion of prior adjuvant or neoadjuvant therapy at least 6 weeks prior to randomization; ECOG performance status 0 or 1; absence of autoimmune disease; and absence of active brain or leptomeningeal metastases. The trial excluded patients with ocular melanoma. Tumor assessments were conducted 9 weeks after randomization then every 6 weeks for the first year and then every 12 weeks thereafter. The major efficacy outcome measure was overall survival (OS). Additional outcome measures included investigator-assessed progression-free survival (PFS) and ORR per RECIST v1.1.
The trial population characteristics were: median age was 65 years (range: 18 to 87), 59% were male, and 99.5% were White. Disease characteristics were M1c stage disease (61%), cutaneous melanoma (74%), mucosal melanoma (11%), elevated LDH level (37%), PD-L1 ≥5% tumor cell membrane expression (35%), and history of brain metastasis (4%). More patients in the intravenous nivolumab arm had an ECOG performance status of 0 (71% vs. 58%).
CHECKMATE-066 demonstrated a statistically significant improvement in OS for the intravenous nivolumab arm compared with the dacarbazine arm in an interim analysis based on 47% of the total planned events for OS. At the time of analysis, 88% (63/72) of intravenous nivolumab-treated patients had ongoing responses, which included 43 patients with ongoing response of 6 months or longer. Efficacy results are shown in Table 49 and Figure 6.

CHECKMATE-067
CHECKMATE-067 (NCT01844505) was a multicenter, randomized (1:1:1), double-blind trial in 945 patients with previously untreated, unresectable or metastatic melanoma to one of the following arms: intravenous nivolumab and ipilimumab, intravenous nivolumab, or ipilimumab. Patients were required to have completed adjuvant or neoadjuvant treatment at least 6 weeks prior to randomization and have no prior treatment with anti-CTLA-4 antibody and no evidence of active brain metastasis, ocular melanoma, autoimmune disease, or medical conditions requiring systemic immunosuppression.
Patients were randomized to receive:
- Nivolumab 1 mg/kg with ipilimumab 3 mg/kg intravenously every 3 weeks for 4 doses, followed by nivolumab as a single agent at a dose of 3 mg/kg by intravenous infusion every 2 weeks (nivolumab and ipilimumab arm),
- Nivolumab 3 mg/kg by intravenous infusion every 2 weeks (nivolumab arm), or
- Ipilimumab 3 mg/kg intravenously every 3 weeks for 4 doses, followed by placebo every 2 weeks (ipilimumab arm).
Randomization was stratified by PD-L1 expression (≥5% vs. <5% tumor cell membrane expression) as determined by a clinical trial assay, BRAF V600 mutation status, and M stage per the AJCC staging system (M0, M1a, M1b vs. M1c). Tumor assessments were conducted 12 weeks after randomization then every 6 weeks for the first year, and every 12 weeks thereafter. The major efficacy outcome measures were investigator-assessed PFS per RECIST v1.1 and OS. Additional efficacy outcome measures were confirmed ORR and duration of response.
The trial population characteristics were: median age 61 years (range: 18 to 90); 65% male; 97% White; ECOG performance score 0 (73%) or 1 (27%). Disease characteristics were: AJCC Stage IV disease (93%); M1c disease (58%); elevated LDH (36%); history of brain metastases (4%); BRAF V600 mutation-positive melanoma (32%); PD-L1 ≥5% tumor cell membrane expression as determined by the clinical trials assay (46%); and prior adjuvant therapy (22%).
CHECKMATE-067 demonstrated statistically significant improvements in OS and PFS for patients randomized to either intravenous nivolumab-containing arm as compared with the ipilimumab arm. The trial was not designed to assess whether adding ipilimumab to intravenous nivolumab improves PFS or OS compared to intravenous nivolumab as a single agent. Efficacy results are shown in Table 50 and Figure 7.

Based on a minimum follow-up of 48 months, the median OS was not reached (95% CI: 38.2, NR) in the intravenous nivolumab and ipilimumab arm. The median OS was 36.9 months (95% CI: 28.3, NR) in the intravenous nivolumab arm and 19.9 months (95% CI: 16.9, 24.6) in the ipilimumab arm.
Based on a minimum follow-up of 28 months, the median PFS was 11.7 months (95% CI: 8.9, 21.9)in the intravenous nivolumab and ipilimumab arm, 6.9 months (95% CI: 4.3, 9.5) in the intravenous nivolumab arm, and 2.9 months (95% CI: 2.8, 3.2) in the ipilimumab arm. Based on a minimum follow-up of 28 months, the proportion of responses lasting ≥24 months was 55% in the intravenous nivolumab and ipilimumab arm, 56% in the intravenous nivolumab arm, and 39% in the ipilimumab arm.
Adjuvant Treatment Of Melanoma
The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of Stage IIB, Stage IIC, Stage III, or Stage IV melanoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous nivolumab in these melanoma populations.
OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.
CHECKMATE-76K
CHECKMATE-76K (NCT04099251) was a randomized, double-blind trial in 790 patients with completely resected Stage IIB/C melanoma. Patients were randomized (2:1) to receive nivolumab 480 mg or placebo by intravenous infusion every 4 weeks for up to 1 year or until disease recurrence or unacceptable toxicity. Enrollment required complete resection of the primary melanoma with negative margins and a negative sentinel lymph node within 12 weeks prior to randomization, and ECOG performance status of 0 or 1. The trial excluded patients with ocular/uveal or mucosal melanoma, autoimmune disease, any condition requiring systemic treatment with either corticosteroids (≥10 mg daily prednisone or equivalent) or other immunosuppressive medications, as well as patients with prior therapy for melanoma except surgery. Randomization was stratified by AJCC 8th staging system edition (T3b vs. T4a vs. T4b). The major efficacy outcome measure was recurrence-free survival (RFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant metastasis), new primary melanoma, or death, from any cause, whichever occurred first and as assessed by the investigator. Tumor assessments were conducted every 26 weeks during years 13 and every 52 weeks thereafter until year 5.
The trial population characteristics were: median age 62 years (range: 19 to 92), 61% were male, 98% were White, 0.4% Black or African American, 0.1% Asian, and 1.1% race unknown, 2.2% Hispanic or Latino, 58% Not Hispanic or Latino, 40% ethnicity unknown, and 94% had an ECOG performance status of 0. Sixty one percent had stage IIB and 39% had stage IIC melanoma.
CHECKMATE-76K demonstrated a statistically significant improvement in RFS for patients randomized to the intravenous nivolumab arm compared with the placebo arm. Efficacy results are shown in Table 51 and Figure 8.

CHECKMATE-238
CHECKMATE-238 (NCT02388906) was a randomized, double-blind trial in 906 patients with completely resected Stage IIIB/C or Stage IV melanoma. Patients were randomized (1:1) to receive nivolumab 3 mg/kg by intravenous infusion every 2 weeks or ipilimumab 10 mg/kg intravenously every 3 weeks for 4 doses then every 12 weeks beginning at Week 24 for up to 1 year. Enrollment required complete resection of melanoma with margins negative for disease within 12 weeks prior to randomization. The trial excluded patients with a history of ocular/uveal melanoma, autoimmune disease, and any condition requiring systemic treatment with either corticosteroids (≥10 mg daily prednisone or equivalent) or other immunosuppressive medications, as well as patients with prior therapy for melanoma except surgery, adjuvant radiotherapy after neurosurgical resection for lesions of the central nervous system, and prior adjuvant interferon completed ≥6 months prior to randomization. Randomization was stratified by PD-L1 status (positive [based on 5% level] vs. negative/indeterminate) and AJCC stage (Stage IIIB/C vs. Stage IV M1a-M1b vs. Stage IV M1c). The major efficacy outcome measure was recurrence-free survival (RFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant metastasis), new primary melanoma, or death, from any cause, whichever occurs first and as assessed by the investigator. Patients underwent imaging for tumor recurrence every 12 weeks for the first 2 years then every 6 months thereafter.
The trial population characteristics were: median age was 55 years (range: 18 to 86), 58% were male, 95% were White, and 90% had an ECOG performance status of 0. Disease characteristics were AJCC Stage IIIB (34%), Stage IIIC (47%), Stage IV (19%), M1a-b (14%), BRAF V600 mutation positive (42%), BRAF wild-type (45%), elevated LDH (8%), PD-L1 ≥5% tumor cell membrane expression determined by clinical trial assay (34%), macroscopic lymph nodes (48%), and tumor ulceration (32%).
CHECKMATE-238 demonstrated a statistically significant improvement in RFS for patients randomized to the intravenous nivolumab arm compared with the ipilimumab 10 mg/kg arm. Efficacy results are shown in Table 52 and Figure 9.

Neoadjuvant Treatment Of Resectable Non-Small Cell Lung Cancer
The effectiveness of OPDIVO QVANTIG has been established for the neoadjuvant treatment of resectable (tumors ≥4 cm or node positive) NSCLC in combination with platinum doublet chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab (CHECKMATE-816, NCT02998528), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this lung cancer population.
CHECKMATE-816
CHECKMATE-816 (NCT02998528) was a randomized, open label trial in patients with resectable NSCLC. The trial included patients with resectable, histologically confirmed Stage IB (≥4 cm), II, or IIIA NSCLC (per the 7th edition American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) staging criteria), ECOG performance status 0 or 1, and measurable disease (per RECIST version 1.1). Patients with unresectable or metastatic NSCLC, known EGFR mutations or ALK translocations, Grade 2 or greater peripheral neuropathy, active autoimmune disease, or medical conditions requiring systemic immunosuppression were excluded from the study.
Patients were randomized to receive either:
- nivolumab 360 mg administered intravenously over 30 minutes and platinum-doublet chemotherapy administered intravenously every 3 weeks for up to 3 cycles, or
- platinum-doublet chemotherapy administered every 3 weeks for up to 3 cycles.
Platinum-doublet chemotherapy consisted of paclitaxel 175 mg/m2 or 200 mg/m2 and carboplatin AUC 5 or AUC 6 (any histology); pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 (non-squamous histology); or gemcitabine 1000 mg/m2 or 1250 mg/m2 and cisplatin 75 mg/m2 (squamous histology). In the platinum-doublet chemotherapy arm, two additional treatment regimen options included vinorelbine 25 mg/m2 or 30 mg/m2 and cisplatin 75 mg/m2; or docetaxel 60 mg/m2 or 75 mg/m2 and cisplatin 75 mg/m2 (any histology).
Stratification factors for randomization were tumor PD-L1 expression level (≥1% versus <1% or non-quantifiable), disease stage (IB/II versus IIIA), and sex (male versus female). Tumor assessments were performed at baseline, within 14 days of surgery, every 12 weeks after surgery for 2 years, then every 6 months for 3 years, and every year for 5 years until disease recurrence or progression. The major efficacy outcome measures were event-free survival (EFS) based on blinded independent central review (BICR) assessment and pathologic complete response (pCR) as evaluated by blinded independent pathology review (BIPR). Additional efficacy outcome measures included OS.
A total of 358 patients were randomized to receive either intravenous nivolumab in combination with platinum-doublet chemotherapy (n=179) or platinum-doublet chemotherapy (n=179). The median age was 65 years (range: 34 to 84) with 51% of patients ≥65 years and 7% of patients ≥75 years, 50% were Asian, 47% were White, 2% were Black, and 71% were male. Baseline ECOG performance status was 0 (67%) or 1 (33%); 50% had tumors with PD-L1 expression ≥1%; 35% had stage IB/II and 64% had stage IIIA disease; 51% had tumors with squamous histology and 49% had tumors with non-squamous histology; and 89% were former/current smokers.
Eighty-three percent of patients in the intravenous nivolumab in combination with platinum-doublet chemotherapy arm had definitive surgery compared to 75% of patients in the platinum-doublet chemotherapy arm.
The study demonstrated statistically significant improvements in EFS and pCR. Efficacy results are presented in Table 53 and Figure 10.

Neoadjuvant And Adjuvant Treatment Of Resectable Non-Small Cell Lung Cancer
The effectiveness of OPDIVO QVANTIG has been established for neoadjuvant treatment of resectable (tumors ≥4 cm or node positive) NSCLC and no EGFR mutations or ALK rearrangements in combination with platinum doublet chemotherapy followed by adjuvant treatment with intravenous nivolumab. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab (CHECKMATE-77T, NCT04025879), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this lung cancer population.
CHECKMATE-77T
The efficacy of intravenous nivolumab, in combination with platinum-doublet chemotherapy, followed by surgery, and continued adjuvant treatment with intravenous nivolumab as a single agent, was investigated in CHECKMATE-77T (NCT04025879), a randomized, double-blind trial in 461 patients with resectable NSCLC. The trial included patients with resectable, suspected or histologically confirmed Stage IIA (>4 cm) to IIIB (T3-T4 N2) NSCLC (per the 8th edition American Joint Committee on Cancer (AJCC) Staging Manual), and ECOG performance status 0 or 1. Patients with unresectable or metastatic NSCLC, EGFR mutations or known ALK translocations, brain metastasis, Grade 2 or greater peripheral neuropathy, interstitial lung disease or active, non-infectious pneumonitis (symptomatic and/or requiring treatment), active autoimmune disease, or medical conditions requiring systemic immunosuppression were excluded from the study. Randomization was stratified by tumor PD-L1 expression level (≥1% versus <1% versus indeterminate/not evaluable), disease stage (Stage II versus Stage III), and tumor histology (squamous versus nonsquamous).
Patients were randomized (1:1) to receive either:
or
All study medications were administered via intravenous infusion. Treatment continued until disease progression, recurrence, or unacceptable toxicity for up to 13 cycles (1 year). Tumor assessments were performed every 12 weeks for 2 years, then every 24 weeks for up to 5 years or until disease recurrence or progression was confirmed by BICR.
The trial was not designed to isolate the effect of intravenous nivolumab in each phase (neoadjuvant or adjuvant) of treatment.
The major efficacy outcome measure was event-free survival (EFS) based on BICR assessment. Additional efficacy outcome measures included overall survival (OS), pathologic complete response (pCR), and major pathologic response (MPR).
The median age was 66 years (range: 35 to 86); 71% were male; 72% were White, 25% were Asian, 1.7% were Black, and 1.5% were mixed race/ race unknown/ not reported; and 6% were Hispanic or Latino. Baseline ECOG performance status was 0 (62%) or 1 (38%); 56% had tumors with PD-L1 expression ≥1% and 40% had tumors with PD-L1 expression <1%; 35% had stage II and 64% had stage III disease; 23% had N1 disease and 39% had N2 disease; 51% had tumors with squamous histology and 49% had tumors with nonsquamous histology; and 90% were former/current smokers.
Seventy-eight percent of patients in the neoadjuvant intravenous nivolumab in combination with platinum-doublet chemotherapy followed by adjuvant intravenous nivolumab arm had definitive surgery compared to 77% of patients in the neoadjuvant placebo and platinum-doublet chemotherapy followed by placebo arm.
The study demonstrated a statistically significant improvement in EFS for patients treated with neoadjuvant intravenous nivolumab in combination with platinum-doublet chemotherapy followed by single agent intravenous nivolumab compared with patients randomized to placebo in combination with platinum-doublet chemotherapy followed by placebo. Efficacy results are presented in Table 54 and Figure 11.

Metastatic Non-Small Cell Lung Cancer
Second-Line Treatment Of Metastatic NSCLC
The effectiveness of OPDIVO QVANTIG has been established for the treatment of NSCLC previously treated with platinum-based chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving OPDIVO QVANTIG. Use of OPDIVO QVANTIG for this indication is supported by evidence from adequate and well-controlled studies conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of this adequate and well-controlled study of intravenous nivolumab in this lung cancer population.
CHECKMATE-017
CHECKMATE-017 (NCT01642004) was a randomized (1:1), open-label trial in 272 patients with metastatic squamous NSCLC who had experienced disease progression during or after one prior platinum doublet-based chemotherapy regimen. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=135) or docetaxel 75 mg/m2 intravenously every 3 weeks (n=137). Randomization was stratified by prior paclitaxel vs. other prior treatment and region (US/Canada vs. Europe vs. Rest of World). This trial included patients regardless of their PD-L1 status. The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, symptomatic interstitial lung disease, or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically returned to baseline at least 2 weeks prior to enrollment, and either off corticosteroids, or on a stable or decreasing dose of <10 mg daily prednisone equivalents. The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were investigator-assessed ORR and PFS.
The trial population characteristics were: median age was 63 years (range: 39 to 85) with 44% ≥65 years of age and 11% ≥75 years of age. The majority of patients were White (93%) and male (76%); the majority of patients were enrolled in Europe (57%) with the remainder in US/Canada (32%) and the rest of the world (11%). Baseline ECOG performance status was 0 (24%) or 1 (76%) and 92% were former/current smokers. Baseline disease characteristics of the population as reported by investigators were Stage IIIb (19%), Stage IV (80%), and brain metastases (6%). All patients received prior therapy with a platinum-doublet regimen and 99% of patients had tumors of squamous-cell histology.
The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with docetaxel at the prespecified interim analysis when 199 events were observed (86% of the planned number of events for final analysis). Efficacy results are shown in Table 55 and Figure 12.

Archival tumor specimens were retrospectively evaluated for PD-L1 expression. Across the trial population, 17% of 272 patients had non-quantifiable results. Among the 225 patients with quantifiable results, 47% had PD-L1 negative squamous NSCLC, defined as <1% of tumor cells expressing PD-L1 and 53% had PD-L1 positive squamous NSCLC defined as ≥1% of tumor cells expressing PD-L1. In pre-specified exploratory subgroup analyses, the hazard ratios for survival were 0.58 (95% CI: 0.37, 0.92) in the PD-L1 negative subgroup and 0.69 (95% CI: 0.45, 1.05) in the PD-L1 positive subgroup.

CHECKMATE-057 (NCT01673867) was a randomized (1:1), open-label trial in 582 patients with metastatic non-squamous NSCLC who had experienced disease progression during or after one prior platinum doublet-based chemotherapy regimen. Appropriate prior targeted therapy in patients with known sensitizing EGFR mutation or ALK translocation was allowed. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks (n=292) or docetaxel 75 mg/m2 intravenously every 3 weeks (n=290). Randomization was stratified by prior maintenance therapy (yes vs. no) and number of prior therapies (1 vs. 2). The trial excluded patients with autoimmune disease, medical conditions requiring systemic immunosuppression, symptomatic interstitial lung disease, or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically stable. The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were investigator-assessed ORR and PFS. In addition, prespecified analyses were conducted in subgroups defined by PD-L1 expression.
The trial population characteristics: median age was 62 years (range: 21 to 85) with 42% of patients ≥65 years and 7% of patients ≥75 years. The majority of patients were White (92%) and male (55%); the majority of patients were enrolled in Europe (46%) followed by the US/Canada (37%) and the rest of the world (17%). Baseline ECOG performance status was 0 (31%) or 1 (69%), 79% were former/current smokers, 3.6% had NSCLC with ALK rearrangement, 14% had NSCLC with EGFR mutation, and 12% had previously treated brain metastases. Prior therapy included platinum-doublet regimen (100%) and 40% received maintenance therapy as part of the first-line regimen. Histologic subtypes included adenocarcinoma (93%), large cell (2.4%), and bronchoalveolar (0.9%).
CHECKMATE-057 demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with docetaxel at the prespecified interim analysis when 413 events were observed (93% of the planned number of events for final analysis). Efficacy results are shown in Table 56 and Figure 13.

Archival tumor specimens were evaluated for PD-L1 expression following completion of the trial. Across the trial population, 22% of 582 patients had non-quantifiable results. Of the remaining 455 patients, the proportion of patients in retrospectively determined subgroups based on PD-L1 testing using the PD-L1 IHC 28-8 pharmDx assay were: 46% PD-L1 negative, defined as <1% of tumor cells expressing PD-L1 and 54% had PD-L1 expression, defined as ≥1% of tumor cells expressing PD-L1. Among the 246 patients with tumors expressing PD-L1, 26% had ≥1% but <5% tumor cells with positive staining, 7% had ≥5% but <10% tumor cells with positive staining, and 67% had ≥10% tumor cells with positive staining. Figures 14 and 15 summarize the results of prespecified analyses of OS and PFS in subgroups determined by percentage of tumor cells expressing PD-L1.

Recurrent Or Metastatic Squamous Cell Carcinoma Of The Head And Neck
The effectiveness of OPDIVO QVANTIG has been established for the treatment of recurrent or metastatic squamous cell carcinoma of the head and neck with disease progression on or after platinum-based therapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this head and neck carcinoma population.
CHECKMATE-141
CHECKMATE-141 (NCT02105636) was a randomized (2:1), active-controlled, open-label trial enrolling patients with metastatic or recurrent SCCHN who had experienced disease progression during or within 6 months of receiving platinum-based therapy administered in either the adjuvant, neo-adjuvant, primary (unresectable locally advanced) or metastatic setting. The trial excluded patients with autoimmune disease, medical conditions requiring immunosuppression, recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma of unknown primary histology, salivary gland or non-squamous histologies (e.g., mucosal melanoma), or untreated brain metastasis. Patients with treated brain metastases were eligible if neurologically stable. Patients were randomized to receive nivolumab 3 mg/kg by intravenous infusion every 2 weeks or investigator’s choice of cetuximab (400 mg/m2 initial dose intravenously followed by 250 mg/m2 weekly), or methotrexate (40 to 60 mg/m2 intravenously weekly), or docetaxel (30 to 40 mg/m2 intravenously weekly).
Randomization was stratified by prior cetuximab treatment (yes/no). The first tumor assessments were conducted 9 weeks after randomization and continued every 6 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were PFS and ORR.
A total of 361 patients were randomized; 240 patients to the intravenous nivolumab arm and 121 patients to the investigator’s choice arm (docetaxel: 45%; methotrexate: 43%; and cetuximab: 12%). The trial population characteristics were: median age was 60 years (range: 28 to 83) with 31% ≥65 years of age, 83% were White, 12% Asian, and 4% were Black, and 83% male. Baseline ECOG performance status was 0 (20%) or 1 (78%), 76% were former/current smokers, 90% had Stage IV disease, 45% of patients received only one prior line of systemic therapy, the remaining 55% received two or more prior lines of systemic therapy, and 25% had HPVp16-positive tumors, 24% had HPV p16-negative tumors, and 51% had unknown status.
The trial demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with investigator’s choice at a pre-specified interim analysis (78% of the planned number of events for final analysis). There were no statistically significant differences between the two arms for PFS (HR=0.89; 95% CI: 0.70, 1.13) or ORR (13.3% [95% CI: 9.3, 18.3] vs. 5.8% [95% CI: 2.4, 11.6] for nivolumab and investigator’s choice, respectively).

Archival tumor specimens were retrospectively evaluated for PD-L1 expression using the PD-L1 IHC 28-8 pharmDx assay. Across the trial population, 28% (101/361) of patients had non-quantifiable results. Among the 260 patients with quantifiable results, 43% (111/260) had PD-L1 negative SCCHN, defined as <1% of tumor cells expressing PD-L1, and 57% (149/260) had PDL1 positive SCCHN, defined as ≥1% of tumor cells expressing PD-L1. In pre-specified exploratory subgroup analyses, the hazard ratio for survival was 0.89 (95% CI: 0.54, 1.45) with median survivals of 5.7 and 5.8 months for the nivolumab and chemotherapy arms, respectively, in the PD-L1 negative subgroup. The HR for survival was 0.55 (95% CI: 0.36, 0.83) with median survivals of 8.7 and 4.6 months for the nivolumab and chemotherapy arms, respectively, in the PD-L1 positive SCCHN subgroup.
Urothelial Carcinoma
Adjuvant Treatment Of Urothelial Carcinoma (UC) At High Risk Of Recurrence
The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of UC at high risk of recurrence. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.
CHECKMATE-274
CHECKMATE-274 (NCT02632409) was a randomized, double-blind, placebo-controlled study of adjuvant intravenous nivolumab in patients who were within 120 days of radical resection (R0) of UC of the bladder or upper urinary tract (renal pelvis or ureter) at high risk of recurrence. High risk of recurrence was defined as either 1) ypT2-ypT4a or ypN+ for patients who received neoadjuvant cisplatin or 2) pT3-pT4a or pN+ for patients who did not receive neoadjuvant cisplatin and who also either were ineligible for or refused adjuvant cisplatin. Patients were randomized 1:1 to receive nivolumab 240 mg or placebo by intravenous infusion every 2 weeks until recurrence or until unacceptable toxicity for a maximum treatment duration of 1 year. Patients were stratified by pathologic nodal status (N+ vs. N0/x with <10 nodes removed vs. N0 with ≥10 nodes removed), tumor cells expressing PD-L1 (≥1% vs. <1%/indeterminate as determined by the central lab using the PD-L1 IHC 28-8 pharmDx assay), and use of neoadjuvant cisplatin (yes vs. no).
The trial population characteristics were: median age of 67 years (range: 30 to 92); 76% male; 76% White, 22% Asian, 0.7% Black, and 0.1% American Indian or Alaska Native. Of the 335 (47%) of patients with node-positive UC, 44 (6%) had non–muscle-invasive (<pT2) primary tumors. ECOG performance status was 0 (63%), 1 (35%), or 2 (2%). Prior neoadjuvant cisplatin had been given to 43% of patients; of the 57% who did not receive prior neoadjuvant cisplatin, reasons listed were ineligibility (22%), patient preference (33%), and other/not reported (2%). Tumor PD-L1 expression was ≥1% in 40% of patients, and 21% of patients had upper tract UC.
The major efficacy outcome measures were investigator-assessed DFS in all randomized patients and in patients with tumors expressing PD-L1 ≥1%. DFS was defined as time to first recurrence (local urothelial tract, local non-urothelial tract, or distant metastasis), or death. Additional efficacy outcome measures included OS.
At the pre-specified interim analysis, CHECKMATE-274 demonstrated a statistically significant improvement in DFS for patients randomized to intravenous nivolumab vs. placebo in the all randomized patient population, as well as in the subpopulation of patients with PD-L1 ≥1%, as shown in Table 58 and Figure 17.
In exploratory subgroup analyses in patients with upper tract UC (n=149), no improvement in DFS was observed in the nivolumab arm compared to the placebo arm. The unstratified DFS hazard ratio estimate was 1.15 (95% CI: 0.74, 1.80).
In an exploratory subgroup analysis in patients with PD-L1 expression of <1% (n=414), the unstratified DFS hazard ratio estimate was 0.83 (95% CI: 0.64, 1.08).
OS data is immature with 33% of deaths in the overall randomized population. In the UTUC subpopulation, 37 deaths occurred (20 in the nivolumab arm, 17 in the placebo arm).

First-Line Treatment Of Unresectable Or Metastatic UC
The effectiveness of OPDIVO QVANTIG has been established for the first-line treatment of unresectable or metastatic UC in combination with cisplatin and gemcitabine. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.
CHECKMATE-901
CHECKMATE-901 (NCT 03036098) was a randomized, open-label study in patients with previously untreated unresectable or metastatic UC. Prior neoadjuvant or adjuvant chemotherapy were permitted as long as the disease recurrence took place ≥12 months from completion of therapy. Patients who were ineligible for cisplatin and those with active CNS metastases were excluded. Stratification factors for randomization were PD-L1 status (≥1% vs. <1% or indeterminate) and liver metastasis. Patients were randomized 1:1 to receive either:
- Intravenous nivolumab 360 mg and cisplatin 70 mg/m2 on Day 1 and gemcitabine 1000 mg/m2 on Days 1 and 8 of a 21-day cycle of a 21-day cycle for up to 6 cycles followed by single-agent intravenous nivolumab 480 mg every 4 weeks until disease progression or unacceptable toxicity. In the absence of disease progression or unacceptable toxicity, intravenous nivolumab was continued for up to 2 years from first dose.
- Cisplatin 70 mg/m2 on Day 1 and gemcitabine 1000 mg/m2 on Days 1 and 8 of a 21-day cycle for up to 6 cycles, until disease progression or unacceptable toxicity.
The major efficacy outcome measures were OS and PFS as assessed by BICR using RECIST v1.1. Additional efficacy outcome measures included ORR as assessed by BICR.
The median age was 65 years of age (range: 32 to 86) with 51% of patients ≥65 years of age and 12% of patients ≥75 years of age, 23% were Asian, 72% were White, 0.3% were Black, 0.3% were American Indian or Alaska Native, 4.9% were Other, 12% were Hispanic or Latino, and 77% were male. Baseline ECOG performance status was 0 (53%) or 1 (46%). At baseline, 87% of patients had metastatic UC, including 20% with liver metastases, 11% had locally advanced UC, and 51% had UC histologic variants. Forty-nine (16%) in the intravenous nivolumab in combination with cisplatin-based chemotherapy arm and 43 (14%) in the cisplatin-based chemotherapy arm switched from cisplatin to carboplatin after at least one cycle of cisplatin.
Efficacy results are presented in Table 59 and Figures 18 and 19.

Previously Treated Advanced Or Metastatic Urothelial Carcinoma
The effectiveness of OPDIVO QVANTIG has been established for the treatment of patients with locally advanced or metastatic UC and disease progression during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this UC population.
CHECKMATE-275
CHECKMATE-275 (NCT02387996) was a single-arm trial in 270 patients with locally advanced or metastatic UC who had disease progression during or following platinum-containing chemotherapy or who had disease progression within 12 months of treatment with a platinum-containing neoadjuvant or adjuvant chemotherapy regimen. Patients were excluded for active brain or leptomeningeal metastases, active autoimmune disease, medical conditions requiring systemic immunosuppression, and ECOG performance status >1. Patients received nivolumab 3 mg/kg by intravenous infusion every 2 weeks until unacceptable toxicity or either radiographic or clinical progression. Tumor response assessments were conducted every 8 weeks for the first 48 weeks and every 12 weeks thereafter. Major efficacy outcome measures included confirmed ORR as assessed by IRRC using RECIST v1.1 and DOR.
The median age was 66 years (range: 38 to 90), 78% were male, 86% were White. Twenty-seven percent had non-bladder urothelial carcinoma and 84% had visceral metastases. Thirty-four percent of patients had disease progression following prior platinum-containing neoadjuvant or adjuvant therapy. Twenty-nine percent of patients had received ≥2 prior systemic regimens in the metastatic setting. Thirty-six percent of patients received prior cisplatin only, 23% received prior carboplatin only, and 7% were treated with both cisplatin and carboplatin in the metastatic setting. Forty-six percent of patients had an ECOG performance status of 1. Eighteen percent of patients had a hemoglobin <10 g/dL, and twenty-eight percent of patients had liver metastases at baseline. Patients were included regardless of their PD-L1 status.
Tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory and the results were used to define subgroups for pre-specified analyses. Of the 270 patients, 46% were defined as having PD-L1 expression of ≥1% (defined as ≥1% of tumor cells expressing PD-L1). The remaining 54% of patients were classified as having PD-L1 expression of <1% (defined as <1% of tumor cells expressing PD-L1). Confirmed ORR in all patients and the two PD-L1 subgroups are shown in Table 60. Median time to response was 1.9 months (range: 1.6-7.2). In 77 patients who received prior systemic therapy only in the neoadjuvant or adjuvant setting, the ORR was 23.4% (95% CI: 14.5%, 34.4%).

Microsatellite Instability-High Or Mismatch Repair Deficient Metastatic Colorectal Cancer
The effectiveness of OPDIVO QVANTIG has been established for the treatment of microsatellite instability-high or mismatch repair deficient colorectal cancer (CRC) that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab (CHECKMATE-142, NCT02060188), and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this CRC population.
OPDIVO QVANTIG is not indicated for the treatment of pediatric patients.
CHECKMATE-142
CHECKMATE-142 (NCT02060188) was a multicenter, non-randomized, multiple parallel-cohort, open-label trial conducted in patients with locally determined dMMR or MSI-H metastatic CRC (mCRC) who had disease progression during or after prior treatment with fluoropyrimidine-, oxaliplatin-, or irinotecan-based chemotherapy. Key eligibility criteria were at least one prior line of treatment for metastatic disease, ECOG performance status 0 or 1, and absence of the following: active brain metastases, active autoimmune disease, or medical conditions requiring systemic immunosuppression.
Patients enrolled in the single agent intravenous nivolumab MSI-H mCRC cohort received nivolumab 3 mg/kg by intravenous infusion (IV) every 2 weeks. Patients enrolled in the intravenous nivolumab and ipilimumab MSI-H mCRC cohort received nivolumab 3 mg/kg and ipilimumab 1 mg/kg intravenously every 3 weeks for 4 doses, followed by nivolumab as a single agent at a dose of 3 mg/kg as intravenous infusion every 2 weeks. Treatment in both cohorts continued until unacceptable toxicity or radiographic progression.
Tumor assessments were conducted every 6 weeks for the first 24 weeks and every 12 weeks thereafter. Efficacy outcome measures included ORR and DOR as assessed by BICR using RECIST v1.1.
A total of 74 patients were enrolled in the single-agent MSI-H mCRC intravenous nivolumab cohort. The median age was 53 years (range: 26 to 79) with 23% ≥65 years of age and 5% ≥75 years of age, 59% were male and 88% were White. Baseline ECOG performance status was 0 (43%), 1 (55%), or 3 (1.4%) and 36% were reported to have Lynch Syndrome. Across the 74 patients, 72% received prior treatment with a fluoropyrimidine, oxaliplatin, and irinotecan; 7%, 30%, 28%, 19%, and 16% received 0, 1, 2, 3, or ≥4 prior lines of therapy for metastatic disease, respectively, and 42% of patients had received an anti-EGFR antibody.
A total of 119 patients were enrolled in the intravenous nivolumab and ipilimumab MSI-H mCRC cohort. The median age was 58 years (range: 21 to 88), with 32% ≥65 years of age and 9% ≥75 years of age; 59% were male and 92% were White. Baseline ECOG performance status was 0 (45%) and 1 (55%), and 29% were reported to have Lynch Syndrome. Across the 119 patients, 69% had received prior treatment with a fluoropyrimidine, oxaliplatin, and irinotecan; 10%, 40%, 24%, and 15% received 1, 2, 3, or ≥4 prior lines of therapy for metastatic disease, respectively, and 29% had received an anti-EGFR antibody.
Efficacy results for each of these single-arm cohorts are shown in Table 61.

Hepatocellular Carcinoma
The effectiveness of OPDIVO QVANTIG has been established for the treatment of hepatocellular carcinoma in patients who have been previously treated with sorafenib and following treatment with intravenous nivolumab and ipilimumab. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this hepatocellular carcinoma population.
CHECKMATE-040
CHECKMATE-040 (NCT01658878) was a multicenter, multiple cohort, open-label trial that evaluated the efficacy of intravenous nivolumab as a single agent and in combination with ipilimumab in patients with hepatocellular carcinoma (HCC) who progressed on or were intolerant to sorafenib. Additional eligibility criteria included histologic confirmation of HCC and Child-Pugh Class A cirrhosis. The trial excluded patients with active autoimmune disease, brain metastasis, a history of hepatic encephalopathy, clinically significant ascites, infection with HIV, or active co-infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) or HBV and hepatitis D virus (HDV); however, patients with only active HBV or HCV were eligible.
Tumor assessments were conducted every 6 weeks for 48 weeks and then every 12 weeks thereafter. The major efficacy outcome measure was confirmed overall response rate as assessed by BICR using RECIST v1.1 and modified RECIST (mRECIST) for HCC. Duration of response was also assessed.
The efficacy of intravenous nivolumab in combination with ipilimumab was evaluated in 49 patients (Cohort 4) who received intravenous nivolumab 1 mg/kg and ipilimumab 3 mg/kg administered every 3 weeks for 4 doses, followed by single-agent intravenous nivolumab at 240 mg every 2 weeks until disease progression or unacceptable toxicity. The median age was 60 years (range: 18 to 80), 88% were male, 74% were Asian, and 25% were White. Baseline ECOG
performance status was 0 (61%) or 1 (39%). Fifty-seven (57%) percent of patients had active HBV infection, 8% had active HCV infection, and 35% had no evidence of active HBV or HCV. The etiology for HCC was alcoholic liver disease in 16% and non-alcoholic fatty liver disease in 6% of patients. Child-Pugh class and score was A5 for 82% and A6 for 18%; 80% of patients had extrahepatic spread; 35% had vascular invasion; and 51% had AFP levels ≥400 μg/L. Prior cancer treatment history included surgery (74%), radiotherapy (29%), or local treatment (59%). All patients had received prior sorafenib, of whom 10% were unable to tolerate sorafenib; 29% of patients had received 2 or more prior systemic therapies.
Efficacy results are shown in Table 62. The results for intravenous nivolumab in combination with ipilimumab in Cohort 4 are based on a minimum follow-up of 28 months.

Esophageal Cancer
Adjuvant Treatment Of Resected Esophageal Or Gastroesophageal Junction Cancer
The effectiveness of OPDIVO QVANTIG has been established for the adjuvant treatment of resected esophageal or gastroesophageal junction cancer with residual pathologic disease who have received neoadjuvant chemoradiotherapy (CRT). Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this esophageal or gastroesophageal junction cancer population.
CHECKMATE-577
CHECKMATE-577 (NCT02743494) was a randomized, multicenter, double-blind trial in 794 patients with completely resected (negative margins) esophageal or gastroesophageal junction cancer who had residual pathologic disease following concurrent chemoradiotherapy (CRT). Patients were randomized (2:1) to receive either nivolumab 240 mg or placebo by intravenous infusion over 30 minutes every 2 weeks for 16 weeks followed by 480 mg or placebo by intravenous infusion over 30 minutes every 4 weeks beginning at week 17. Treatment was until disease recurrence, unacceptable toxicity, or for up to 1 year in total duration. Enrollment required complete resection within 4 to 16 weeks prior to randomization. The trial excluded patients who did not receive CRT prior to surgery, had stage IV resectable disease, autoimmune disease, or any condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone or equivalent) or other immunosuppressive medications. Randomization was stratified by tumor PDL1 status (≥1% vs. <1% or indeterminate or non-evaluable), pathologic lymph node status (positive ≥ypN1 vs. negative ypN0), and histology (squamous vs. adenocarcinoma). The major efficacy outcome measure was disease-free survival (DFS) defined as the time between the date of randomization and the date of first recurrence (local, regional, or distant from the primary resected site) or death, from any cause, whichever occurred first as assessed by the investigator prior to subsequent anti-cancer therapy. Patients on treatment underwent imaging for tumor recurrence every 12 weeks for 2 years, and a minimum of one scan every 6 to 12 months for years 3 to 5.
The trial population characteristics were: median age 62 years (range: 26 to 86), 36% were ≥65 years of age, 85% were male, 15% were Asian, 82% were White, and 1.1% were Black. Disease characteristics were AJCC Stage II (35%) or Stage III (65%) at initial diagnosis carcinoma, EC (60%) or GEJC (40%) at initial diagnosis, with pathologic positive lymph node status (58%) at study entry and histological confirmation of predominant adenocarcinoma (71%) or squamous cell carcinoma (29%). The baseline Tumor PD-L1 status ≥1% was positive for 16% of patients and negative for 72% of patients. Baseline ECOG performance status was 0 (58%) or 1 (42%).
CHECKMATE-577 demonstrated a statistically significant improvement in DFS for patients randomized to the intravenous nivolumab arm as compared with the placebo arm. DFS benefit was observed regardless of tumor PD-L1 expression and histology.
Efficacy results are shown in Table 63 and Figure 20.

First-Line Treatment Of Unresectable Advanced Or Metastatic Esophageal Squamous Cell Carcinoma (ESCC) Whose Tumors Express PD-L1 (≥1)
The effectiveness of OPDIVO QVANTIG in combination with fluoropyrimidine-and platinum-containing chemotherapy has been established for the first-line treatment of unresectable advanced or metastatic ESCC. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this esophageal squamous cell carcinoma population.
CHECKMATE-648
CHECKMATE-648 (NCT03143153) was a randomized, active-controlled, open-label trial in patients with previously untreated unresectable advanced, recurrent or metastatic ESCC (squamous or adenosquamous histology). The trial enrolled patients whose tumor was evaluable for tumor cell (TC) PD-L1 expression [also called PD-L1 tumor proportion score (TPS)], which was evaluated using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. A retrospective scoring of a patient’s tumor PD-L1 status using Combined Positive Score (CPS), was also conducted using the PD-L1-stained tumor specimens used for randomization. Patients were not amenable to chemoradiation or surgery with curative intent. Prior treatment with curative intent was allowed if completed more than six months prior to trial enrollment. The trial excluded patients with brain metastasis that were symptomatic, had active autoimmune disease, used systemic corticosteroids or immunosuppressants, or patients at high risk of bleeding or fistula due to apparent invasion of tumor to organs adjacent to the esophageal tumor. Patients were randomized to receive one of the following treatments:
- Intravenous nivolumab 240 mg on days 1 and 15, fluorouracil 800 mg/m2/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m2 intravenously on day 1 (of a 4-week cycle).
- Intravenous nivolumab 3 mg/kg every 2 weeks in combination with ipilimumab 1 mg/kg every 6 weeks.
- Fluorouracil 800 mg/m2/day intravenously on days 1 through 5 (for 5 days), and cisplatin 80 mg/m2 intravenously on day 1 (of a 4-week cycle).
Patients received intravenous nivolumab until disease progression, unacceptable toxicity, or up to 2 years. In patients who received intravenous nivolumab in combination with chemotherapy and in whom either fluorouracil and/or cisplatin were discontinued, other components of the treatment regimen were allowed to be continued. Patients who discontinued combination therapy because of an adverse reaction attributed to ipilimumab were permitted to continue intravenous nivolumab as a single agent.
Randomization was stratified by TC PD-L1 expression (≥1% vs. <1% or indeterminate), region (East Asia vs. Rest of Asia vs. Rest of World), ECOG performance status (0 vs. 1), and number of organs with metastases (≤1 vs. ≥2). The major efficacy outcome measures were OS and BICR-assessed PFS in patients with TC PD-L1 expression ≥1%. Additional efficacy measures included OS in all randomized patients, BICR-assessed PFS in all randomized patients, and ORR assessed by BICR in TC PD-L1 expression ≥1% and in all randomized patients. The tumor assessments per RECIST v1.1 were conducted every 6 weeks up to and including week 48, then every 12 weeks thereafter.
A total of 970 patients were randomized in CHECKMATE-648 study among whom 965 and 906 patients had quantifiable TC PD-L1 expression and CPS at baseline, respectively; 85% (824/970) had tumors with PD-L1 CPS ≥1. The trial population characteristics in patients with PD-L1 CPS ≥1 were median age 63 years (range: 26 to 90), 46% were ≥65 years of age, 82% were male, 71% were Asian, 25% were White, and 1.2% were Black or African American. Patients had histological confirmation of squamous cell carcinoma (99%) or adenosquamous cell carcinoma (1.7%) in the esophagus. Baseline ECOG performance status was 0 (44.0%) or 1 (54%).
A statistically significant improvement in OS was demonstrated in patients randomized to intravenous nivolumab in combination with chemotherapy and patients randomized to intravenous nivolumab in combination with ipilimumab compared with chemotherapy. An exploratory analysis of OS in patients with PD-L1 CPS <1 showed a HR of 0.98 (95% CI 0.50, 1.95) for the comparison of intravenous nivolumab in combination with chemotherapy, and the exploratory analysis OS in patients with PD-L1 CPS <1 showed a HR of 1.0 (95% CI 0.52, 1.94) for the comparison of intravenous nivolumab in combination with ipilimumab; these results indicate that the improvement in the ITT population was primarily attributed to the results observed in the subgroup of patients with PD-L1 CPS ≥1. Efficacy results are shown in Table 64 and Figures 21 and 22.

Previously Treated Unresectable Advanced, Recurrent Or Metastatic ESCC
The effectiveness of OPDIVO QVANTIG has been established for the treatment of unresectable advanced, recurrent, or metastatic ESCC after prior fluoropyrimidine-and platinum-based chemotherapy. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this ESCC population.
ATTRACTION-3
ATTRACTION-3 (NCT02569242) was a multicenter, randomized (1:1), active-controlled, open-label trial in patients with unresectable advanced, recurrent, or metastatic ESCC, who were refractory or intolerant to at least one fluoropyrimidine-and platinum-based regimen. The trial enrolled patients regardless of PD-L1 status, but tumor specimens were evaluated prospectively using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory. The trial excluded patients who were refractory or intolerant to taxane therapy, had brain metastases that were symptomatic or required treatment, had autoimmune disease, used systemic corticosteroids or immunosuppressants, or had apparent tumor invasion of organs adjacent to the esophageal tumor or had stents in the esophagus or respiratory tract. Patients were randomized to receive nivolumab 240 mg by intravenous infusion over 30 minutes every 2 weeks or investigator’s choice of taxane chemotherapy consisting of docetaxel (75 mg/m2 intravenously every 3 weeks) or paclitaxel (100 mg/m2 intravenously once a week for 6 weeks followed by 1 week off).
Randomization was stratified by region (Japan vs. Rest of World), number of organs with metastases (≤1 vs. ≥2), and PD-L1 status (≥1% vs. <1% or indeterminate). Patients were treated until disease progression, assessed by the investigator per RECIST v1.1, or unacceptable toxicity. The tumor assessments were conducted every 6 weeks for 1 year, and every 12 weeks thereafter. The major efficacy outcome measure was OS. Additional efficacy outcome measures were ORR and PFS as assessed by the investigator using RECIST v1.1 and DOR.
A total of 419 patients were randomized; 210 to the intravenous nivolumab arm and 209 to the investigator’s choice arm (docetaxel: 31%, paclitaxel: 69%). The trial population characteristics were: median age 65 years (range: 33 to 87), 53% were ≥65 years of age, 87% were male, 96% were Asian and 4% were White. Sixty-seven percent of patients had received one prior systemic therapy regimen and 26% had received two prior systemic therapy regimens prior to enrolling in ATTRACTION-3. Baseline ECOG performance status was 0 (50%) or 1 (50%).
ATTRACTION-3 demonstrated a statistically significant improvement in OS for patients randomized to intravenous nivolumab as compared with investigator’s choice of taxane chemotherapy. OS benefit was observed regardless of PD-L1 expression level. OS results by PDL1 CPS level (<1 and ≥1) were not studied. The minimum follow-up was 17.6 months. Efficacy results are shown in Table 65 and Figure 23.

Figure 23: Overall Survival -ATTRACTION-3
Of the 419 patients, 48% had PD-L1 positive ESCC, defined as ≥1% of tumor cells expressing PD-L1. The remaining 52% had PD-L1 negative ESCC defined as <1% of tumor cells expressing PD-L1.
In a pre-specified exploratory analysis by PD-L1 status, the hazard ratio (HR) for OS was 0.69 (95% CI: 0.51, 0.94) with median survivals of 10.9 and 8.1 months for the intravenous nivolumab and investigator’s choice arms, respectively, in the PD-L1 positive subgroup. In the PD-L1 negative subgroup, the HR for OS was 0.84 (95% CI: 0.62, 1.14) with median survivals of 10.9 and 9.3 months for the intravenous nivolumab and investigator’s choice arms, respectively.
Gastric Cancer, Gastroesophageal Junction Cancer, And EsophagealAdenocarcinoma Whose Tumors Express PD-L1 (≥1)
The effectiveness of OPDIVO QVANTIG in combination with fluoropyrimidine-and platinum-containing chemotherapy has been established for the treatment of gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma. Use of OPDIVO QVANTIG for this indication is supported by evidence from an adequate and well-controlled study conducted with intravenous nivolumab, and additional pharmacokinetic and safety data that demonstrated comparable pharmacokinetics and safety profiles between OPDIVO QVANTIG and intravenous nivolumab [see ADVERSE REACTIONS and CLINICAL PHARMACOLOGY]. Below is a description of the efficacy results of the adequate and well-controlled study of intravenous nivolumab in this population.
CHECKMATE-649
CHECKMATE-649 (NCT02872116) was a randomized, multicenter, open-label trial in patients (n=1581) with previously untreated advanced or metastatic gastric cancer, gastroesophageal junction cancer, and esophageal adenocarcinoma. The trial enrolled patients regardless of PD-L1 status, and tumor specimens were evaluated using the PD-L1 IHC 28-8 pharmDx assay at a central laboratory (tumor cell [TC] and Combined Positive Score [CPS]). The trial excluded patients who were known human epidermal growth factor receptor 2 (HER2) positive, or had untreated CNS metastases. Patients were randomized to receive intravenous nivolumab in combination with chemotherapy (n=789) or chemotherapy (n=792). Patients received one of the following treatments:
- Intravenous nivolumab 240 mg in combination with mFOLFOX6 (fluorouracil, leucovorin and oxaliplatin) every 2 weeks or mFOLFOX6 every 2 weeks.
- Intravenous nivolumab 360 mg in combination with CapeOX (capecitabine and oxaliplatin) every 3 weeks or CapeOX every 3 weeks.
Patients were treated until disease progression, unacceptable toxicity, or up to 2 years. In patients who received intravenous nivolumab in combination with chemotherapy and in whom chemotherapy was discontinued, intravenous nivolumab monotherapy was allowed to be given at 240 mg every 2 weeks, 360 mg every 3 weeks, or 480 mg every 4 weeks up to 2 years after treatment initiation.
Randomization was stratified by tumor cell PD-L1 status (≥1% vs. <1% or indeterminate), region (Asia vs. US vs. Rest of World), ECOG performance status (0 vs. 1), and chemotherapy regimen (mFOLFOX6 vs. CapeOX). The major efficacy outcome measures, assessed in patients with PDL1 CPS ≥5, were PFS assessed by BICR and OS. Additional efficacy outcome measures included OS and PFS in patients with PD-L1 CPS ≥1 and in all randomized patients, and ORR and DOR as assessed by BICR in patients with PD-L1 CPS ≥1 and ≥5, and in all randomized patients. Tumor assessments were conducted per RECIST v1.1 every 6 weeks up to and including week 48, then every 12 weeks thereafter.
A total of 1581 patients were randomized in the CHECKMATE-649 study, among whom 1296 and 955 had baseline PD-L1 CPS ≥1 and CPS ≥5, respectively. The trial population characteristics in patients with PD-L1 CPS ≥ 1 were: median age 62 years (range: 18 to 90), 40% were ≥65 years of age, 72% were male, 23% were Asian, and 69% were White, and 1% were Black or African American. Baseline ECOG performance status was 0 (42%) or 1 (58%). Seventy percent of patients had adenocarcinoma tumors in the stomach, 17% in the gastroesophageal junction, and 13% in the esophagus.
CHECKMATE-649 demonstrated a statistically significant improvement in OS and PFS for patients with PD-L1 CPS ≥5. Statistically significant improvement in OS was also demonstrated for all randomized patients and patients with PD-L1 CPS ≥1. Exploratory analysis of OS in the CPS <1 population showed a hazard ratio of 0.85 (95% CI: 0.63, 1.15), indicating that the improvement in the ITT population was primarily attributed to the results observed in the subgroup of patients with PD-L1 CPS ≥1. The minimum follow-up was 12.1 months. Efficacy results are shown in Table 66 and Figures 24 and 25.
