Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be compared to rates in the clinical trials of another drug and may not reflect the rates observed in the general patient population.

The pooled safety population described in WARNINGS AND PRECAUTIONS reflects exposure to UKONIQ as monotherapy at a dosage of 800 mg orally once daily in 335 adults with hematologic malignancies in studies TGR-1202-101, TGR-1202-202, UTX-TGR-205, and UTXTGR- 501. Among these 335 patients who received UKONIQ, 52% were exposed for 6 months or longer and 30% were exposed for greater than one year.

Relapsed Or Refractory Follicular Lymphoma And Marginal Zone Lymphoma

The safety of UKONIQ was evaluated in a pooled safety population that included 221 adults with marginal zone lymphoma (37%) and follicular lymphoma (63%) enrolled in three singlearm, open-label trials (Study TGR-1202-101, TGR-1202-202, and UTX-TGR-205) and one open-label extension trial (Study UTX-TGR-501) [see Clinical Studies]. These trials required hepatic transaminases ≤ 2.5 times upper limit of normal (ULN), total bilirubin ≤ 1.5 times ULN, and creatinine clearance ≥ 30 mL/min. No patients had prior exposure to a PI3K inhibitor. Patients received UKONIQ 800 mg orally once daily. Among these 221 patients who received UKONIQ, 60% were exposed for 6 months or longer and 34% were exposed for greater than one year.

The median age was 66 years (range: 29 to 88 years), 43% were female, and 97% had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Race was reported in 92% of patients; of these patients, 89% were White, 6% were Black, and 3% were Asian. Patients had a median of 2 prior therapies (range 1 to 10).

Serious adverse reactions occurred in 18% of patients who received UKONIQ. Serious adverse reactions that occurred in ≥2% of patients were diarrhea-colitis (4%), pneumonia (3%), sepsis (2%), and urinary tract infection (2%). Fatal adverse reactions occurred in <1% of patients who received UKONIQ, including exfoliative dermatitis.

Permanent discontinuation of UKONIQ due to an adverse reaction occurred in 14% of patients. Adverse reactions which resulted in permanent discontinuation of UKONIQ in ≥5% of patients included diarrhea-colitis (6%) and transaminase elevation (5%).

Dose reductions of UKONIQ due to an adverse reaction occurred in 11% of patients. Adverse reactions which required dose reductions in ≥4% of patients included diarrhea-colitis (4%).

Dosage interruptions of UKONIQ due to an adverse reaction occurred in 43% of patients. Adverse reactions which required dosage interruption in ≥5% of patients included diarrheacolitis (18%), transaminase elevation (7%), neutropenia (5%), vomiting (5%), and upper respiratory tract infection (5%).

The most frequent Grade ≥3 infections included pneumonia, sepsis, and urinary tract infection. The median time to onset of Grade ≥3 infection was 2.4 months (range: 1 day to 21 months) [see ADVERSE REACTIONS].

Monitor for any new or worsening signs and symptoms of infection. For Grade 3 or 4 infection, withhold UKONIQ until infection has resolved. Resume UKONIQ at the same or a reduced dose [see DOSAGE AND ADMINISTRATION].

Provide prophylaxis for Pneumocystis jirovecii pneumonia (PJP) during treatment with UKONIQ [see DOSAGE AND ADMINISTRATION]. Withhold UKONIQ in patients with suspected PJP of any grade and permanently discontinue in patients with confirmed PJP [see DOSAGE AND ADMINISTRATION].

Monitor for cytomegalovirus (CMV) infection during treatment with UKONIQ in patients with a history of CMV infection. Consider prophylactic antivirals during treatment with UKONIQ to prevent CMV infection, including CMV reactivation [see DOSAGE AND ADMINISTRATION]. For clinical CMV infection or viremia, withhold UKONIQ until infection or viremia resolves. If UKONIQ is resumed, administer the same or reduced dose and monitor patients for CMV reactivation by PCR or antigen test at least monthly [see DOSAGE AND ADMINISTRATION].

Neutropenia

Serious neutropenia occurred in patients treated with UKONIQ. Grade 3 neutropenia developed in 9% of 335 patients and Grade 4 neutropenia developed in 9% [see ADVERSE REACTIONS]. The median time to onset of Grade 3 or 4 neutropenia was 45 days.

Monitor neutrophil counts at least every 2 weeks for the first 2 months of UKONIQ and at least weekly in patients with neutrophil counts <1 ×109/L (Grade 3-4). Consider supportive care as appropriate. Withhold, reduce dose, or discontinue UKONIQ depending on the severity and persistence of neutropenia [see DOSAGE AND ADMINISTRATION].

Diarrhea Or Non-Infectious Colitis

Serious diarrhea or non-infectious colitis occurred in patients treated with UKONIQ. Any grade diarrhea or colitis occurred in 53% of 335 patients and Grade 3 occurred in 9% [see ADVERSE REACTIONS]. The median time to onset for any grade diarrhea or colitis was 1 month (range: 1 day to 23 months), with 75% of cases occurring by 2.9 months.

For patients with severe diarrhea (Grade 3, i.e., > 6 stools per day over baseline) or abdominal pain, stool with mucus or blood, change in bowel habits, or peritoneal signs, withhold UKONIQ until resolved and provide supportive care with antidiarrheals or enteric acting steroids as appropriate. Upon resolution, resume UKONIQ at a reduced dose. For recurrent Grade 3 diarrhea or recurrent colitis of any grade, discontinue UKONIQ. Discontinue UKONIQ for lifethreatening diarrhea or colitis [see DOSAGE AND ADMINISTRATION].

Hepatotoxicity

Serious hepatotoxicity occurred in patients treated with UKONIQ. Grade 3 and 4 transaminase elevations (ALT and/or AST) occurred in 8% and <1%, respectively, in 335 patients [see ADVERSE REACTIONS]. The median time to onset for Grade 3 or higher transaminase elevations was 2.2 months (range: 15 days to 4.7 months).

Monitor hepatic function at baseline and during treatment with UKONIQ. For ALT/AST greater than 5 to less than 20 times ULN, withhold UKONIQ until return to less than 3 times ULN, then resume at a reduced dose. For ALT/AST elevation greater than 20 times ULN, discontinue UKONIQ [see DOSAGE AND ADMINISTRATION].

Severe Cutaneous Reactions

Severe cutaneous reactions, including a fatal case of exfoliative dermatitis, occurred in patients treated with UKONIQ. Grade 3 cutaneous reactions occurred in 2% of 335 patients and included exfoliative dermatitis, erythema, and rash (primarily maculo-papular) [see ADVERSE REACTIONS]. The median time to onset of Grade 3 or higher cutaneous reaction was 15 days (range: 9 days to 6.4 months).

Monitor patients for new or worsening cutaneous reactions. Review all concomitant medications and discontinue any potentially contributing medications. Withhold UKONIQ for severe (Grade 3) cutaneous reactions until resolution. Monitor at least weekly until resolved. Upon resolution, resume UKONIQ at a reduced dose. Discontinue UKONIQ if severe cutaneous reaction does not improve, worsens, or recurs. Discontinue UKONIQ for life-threatening cutaneous reactions or SJS, TEN, or DRESS of any grade [see DOSAGE AND ADMINISTRATION]. Provide supportive care as appropriate.

Allergic Reactions Due To Inactive Ingredient Fd&C Yellow No. 5

UKONIQ contains FD&C Yellow No. 5 (tartrazine), which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.

Embryo-Fetal Toxicity

Based on findings in animals and its mechanism of action, UKONIQ can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of umbralisib to pregnant mice during the period of organogenesis caused adverse developmental outcomes including embryo-fetal mortality and fetal malformations at maternal exposures comparable to those in patients at the recommended dose of 800 mg. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment and for one month after the last dose [see Use In Specific Populations].

Patient Counseling Information

Advise patients to read the FDA-approved patient labeling (Medication Guide).

Infections

Advise patients that UKONIQ can cause serious infections that may be fatal. Advise patients to immediately report any signs or symptoms of infection (e.g., fever, chills, weakness) [see WARNINGS AND PRECAUTIONS].

Neutropenia

Advise patients of the need for periodic monitoring of blood counts and to notify their healthcare provider immediately if they develop a fever or any signs of infection [see WARNINGS AND PRECAUTIONS].

Advise patients that they may experience loose stools or diarrhea and should contact their healthcare provider with any persistent or worsening diarrhea. Advise patients to maintain adequate hydration [see WARNINGS AND PRECAUTIONS].

Advise patients of the possibility of colitis and to notify their healthcare provider of any abdominal pain/distress [see WARNINGS AND PRECAUTIONS].

Hepatotoxicity

Advise patients that UKONIQ may cause significant elevations in liver enzymes and the need for periodic monitoring of liver tests. Advise patients to report symptoms of liver dysfunction including jaundice (yellow eyes or yellow skin), abdominal pain, bruising, or bleeding [see WARNINGS AND PRECAUTIONS].

Severe Cutaneous Reactions

Advise patients that UKONIQ may cause a severe skin rash and to notify their healthcare provider immediately if they develop a new or worsening skin rash [see WARNINGS AND PRECAUTIONS].

Embryo-Fetal Toxicity

Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to inform their healthcare provider of a known or suspected pregnancy [see WARNINGS AND PRECAUTIONS, Use In Specific Populations].

Advise females of reproductive potential to use effective contraceptive during treatment with UKONIQ and for one month after the last dose [see Use In Specific Populations].

Advise males with female partners of reproductive potential to use effective contraceptive during treatment with UKONIQ and for one month after the last dose [see Use In Specific Populations].

Lactation

Advise women not to breastfeed during treatment with UKONIQ and for one month after the last dose [see Use In Specific Populations].

Infertility

Advise males of reproductive potential that UKONIQ may impair fertility [see Use In Specific Populations].

Allergic Reactions Due To Inactive Ingredient Fd&C Yellow No. 5

Advise patients that UKONIQ contains FD&C Yellow No. 5 (tartrazine), which may cause allergic-type reactions in certain susceptible persons [see WARNINGS AND PRECAUTIONS].

Administration

Inform patients to take UKONIQ orally once daily at approximately the same time each day with food and how to make up a missed or vomited dose. Advise patients to swallow tablets whole. Advise patients not to crush, break, cut or chew tablets [see DOSAGE AND ADMINISTRATION].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity studies have not been conducted with umbralisib.

Umbralisib was not mutagenic in a bacterial mutagenicity (Ames) assay. Umbralisib was not clastogenic in an in vitro micronucleus assay using human (TK6) lymphoblast cells or in an in vivo micronucleus assay in mice at doses up to 1000 mg/kg.

In a repeat-dose toxicology study in dogs, adverse findings in reproductive organs were observed in males and included findings in the testis (decreased weight, tubular degeneration, tubular atrophy) and epididymis (decreased weight, luminal debris) at doses ≥100 mg/kg, which is approximately 0.1 times the human exposure (AUC) at the recommended dose of 800 mg. In a combined male and female fertility study in mice, umbralisib was administered orally at doses of 50, 150, or 300 mg/kg/day, starting 28 days prior to pairing and through mating in males and starting 14 days prior to pairing through Gestation Day 7 in females. Adverse findings were observed at doses of 150 and 300 mg/kg/day and included decreased testicular and epididymis weights, decreased sperm mobility and counts, increased post-implantation loss, and increased resorption. The dose of 150 mg/kg results in an exposure approximately 1.3 times the human exposure (AUC) at the recommended dose of 800 mg.

Use In Specific Populations

Pregnancy

Risk Summary

Based on findings from animal studies and the mechanism of action [see CLINICAL PHARMACOLOGY], UKONIQ can cause fetal harm when administered to a pregnant woman. There are no available data on UKONIQ use in pregnant women to evaluate for a drug-associated risk. In animal reproduction studies, administration of umbralisib to pregnant mice during organogenesis resulted in adverse developmental outcomes, including alterations to growth, embryo-fetal mortality, and structural abnormalities at maternal exposures (AUC) comparable to those in patients at the recommended dose of 800 mg (see Data). Advise pregnant women of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

In an embryo-fetal development study in mice, pregnant animals were administered oral doses of umbralisib at 100, 200, and 400 mg/kg/day during the period of organogenesis. Malformations were observed at doses of 200 mg/kg/day (cleft palate) and 400 mg/kg/day (cleft palate and nasopharyngeal fistula). Additional findings occurred starting at the dose of 100 mg/kg/day and included folded retina, delayed ossification of sternebrae and vertebrae, increased resorptions, and increased post-implantation loss. The exposure (AUC) at a dose of 100 mg/kg/day in mice is approximately equivalent to the human exposure at the recommended dose of 800 mg.

In an embryo-fetal development study in rabbits, pregnant animals were administered oral doses of umbralisib at 30, 100, and 300 mg/kg/day during the period of organogenesis. Administration at 300 mg/kg/day resulted in maternal toxicity (decreased food consumption and body weight) and reduced fetal weights. The exposure (AUC) at 300 mg/kg/day in rabbits is approximately 0.03 times the exposure in human patients at the recommended dose of 800 mg.

Lactation

Risk Summary

There are no data on the presence of umbralisib in human milk or the effects on the breastfed child or milk production. Because of the potential for serious adverse reactions from umbralisib in the breastfed child, advise women not to breastfeed during treatment with UKONIQ and for one month after the last dose.

Females And Males Of Reproductive Potential

UKONIQ may cause fetal harm when administered to a pregnant woman [see Pregnancy].

Pregnancy Testing

Verify pregnancy status in females of reproductive potential prior to initiating UKONIQ.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with UKONIQ and for one month after the last dose.

Males

Advise males with female partners of reproductive potential to use effective contraception during treatment with UKONIQ and for one month after the last dose.

Infertility

Males

Based on the findings from mice and dogs, UKONIQ may impair male fertility [see Nonclinical Toxicology]. Trend for reversibility was noted in dogs 30 days after the last dose.

Pediatric Use

Safety and effectiveness of UKONIQ have not been established in pediatric patients.

Geriatric Use

Of the 221 patients with MZL or FL who received UKONIQ in clinical studies, 56% of patients were 65 years of age and older, while 19% were 75 years of age and older. No overall differences in effectiveness or pharmacokinetics were observed between these patients and younger patients. In patients 65 years of age and older, 23% experienced serious adverse reactions compared to 12% in patients younger than 65 years of age. There was a higher incidence of infectious serious adverse reactions in patients 65 years of age or older (13%) compared to patients younger than 65 years of age (4%).

Renal Impairment

No dose adjustment is recommended in patients with mild or moderate renal impairment (creatinine clearance [CLcr] 30 to 89 mL/min estimated by Cockcroft-Gault equation) [see CLINICAL PHARMACOLOGY]. UKONIQ has not been studied in patients with severe renal impairment ([CLcr] < 30 mL/min).

Hepatic Impairment

No dose adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] and AST > ULN or total bilirubin >1 to 1.5 × ULN and any AST) [see CLINICAL PHARMACOLOGY]. UKONIQ has not been studied in patients with moderate (total bilirubin > 1.5 to 3 × ULN and any AST) or severe hepatic impairment (total bilirubin > 3 × ULN and any AST).

Drug Interactions for Ukoniq

No Information Provided

Contraindications for Ukoniq

None.

Clinical Pharmacology for Ukoniq

Mechanism Of Action

Umbralisib inhibits multiple kinases. In biochemical and cell-based assays, umbralisib inhibited PI3Kδ and casein kinase CK1ε. PI3Kδ is expressed in normal and malignant B-cells; CK1ε has been implicated in the pathogenesis of cancer cells, including lymphoid malignancies. Umbralisib also inhibited a mutated form of ABL1 in biochemical assays. Umbralisib inhibited cell proliferation, CXCL12-mediated cell adhesion, and CCL19-mediated cell migration in lymphoma cell lines in studies conducted in vitro.

Pharmacodynamics

Exposure

Response Relationships

An exposure-response relationship between umbralisib and overall response rate was observed in patients with FL. The time course of pharmacodynamic response is unknown.

A relationship between higher umbralisib steady state exposures and higher incidence of adverse reactions, including diarrhea (any grade) and elevated AST/ALT (any grade and Grade ≥ 3), was observed.

Cardiac Electrophysiology

The effect of UKONIQ on QT interval has not been fully characterized.

Pharmacokinetics

Umbralisib exposures increased proportionally over a dose range of 200 mg to 1000 mg once daily (0.25 to 1.25 times the recommended dosage). A 6.4- and 3.8-fold accumulation of AUC and Cmax of umbralisib, respectively, were observed at the recommended dosage.

The mean (CV%) steady-state AUC and Cmax were 141 μg*h/mL (46%) and 7.3 μg/mL (39%), respectively, at the recommended dosage.

Absorption

The median time to reach peak plasma concentration (tmax) is approximately 4 hours.

Effect of Food

Administration of a single dose of UKONIQ with a high-fat, high calorie meal (approximately 917 calories with 171 calories from protein, 232 calories from carbohydrate, and 502 calories from fat) in healthy subjects increased AUC and Cmax of umbralisib by 61% and 115%, respectively, relative to fasting conditions.

Distribution

The mean (CV%) apparent central volume of distribution of umbralisib is 312 (185%) L.

The plasma protein binding is ≥99.7% and was independent of concentration between 2 and 5 μM. Mean blood-to-plasma ratio is 0.6.

Elimination

The mean (CV%) apparent clearance of umbralisib is 15.5 (52%) L/h with effective half-life of 91 (42%) hours.

Metabolism

Umbralisib is metabolized by CYP2C9, CYP3A4, and CYP1A2 in vitro.

Excretion

Approximately 81% of the dose was recovered in feces (17% unchanged) and 3% in urine (0.02% unchanged) following a single radiolabeled dose of umbralisib 800 mg to healthy subjects.

Specific Populations

No clinically significant differences in the pharmacokinetics of umbralisib were observed based on age (18 to 87 years old), sex, race (White and Black), body weight (44 to 165 kg), mild hepatic impairment (total bilirubin ≤ ULN and AST > ULN or total bilirubin >1 to 1.5 × ULN and any AST), or mild and moderate renal impairment (CLcr 30 to 89 mL/min, estimated by the Cockcroft-Gault equation). The effect of other race/ethnicity, severe renal impairment (CLcr 15 to 29 mL/min) and dialysis, or moderate to severe hepatic impairment (total bilirubin ≤ ULN and AST > ULN or total bilirubin > ULN and any AST) on umbralisib pharmacokinetics is unknown.

Drug Interaction Studies

Clinical Studies

No clinically significant differences in umbralisib pharmacokinetics were observed when used concomitantly with omeprazole, a proton pump inhibitor.

Coadministration of UKONIQ with strong CYP3A4 inhibitors and inducers or moderate CYP2C9 inhibitors and inducers have not been studied.

Coadministration of UKONIQ with sensitive substrates of CYP3A4, CYP2C8, CYP2C9 and CYP2C19, or P-gp substrates have not been fully characterized.

In Vitro Studies

Cytochrome P450 (CYP) Enzymes

Umbralisib is a substrate of CYP1A2, CYP2C9, and CYP3A4, but is not a substrate of CYP2B6, CYP2C8, CYP2C19, CYP2D6, and UGT1A1.

Umbralisib inhibits CYP2C8, CYP2C9, CYP2C19, and CYP3A4, but does not inhibit CYP1A2, CYP2B6, and CYP2D6. Umbralisib induces CYP3A4.

Transporter Systems

Umbralisib is not a substrate to P-gp, BCRP, OAT1, OAT3, OCT2, OATP1B1, OATP1B3, MATE1, and MATE2-K.

Umbralisib inhibits P-gp.

Clinical Studies

Marginal Zone Lymphoma

The efficacy of UKONIQ was evaluated in a single-arm cohort of Study UTX-TGR-205 (NCT02793583), an open-label, multi-center, multi-cohort trial. Patients with MZL were required to have received at least one prior therapy, including an anti-CD20 containing regimen. The trial excluded patients with prior exposure to a PI3K inhibitor. Patients received UKONIQ 800 mg orally once daily until disease progression or unacceptable toxicity.

A total of 69 patients with MZL [extranodal (N=38), nodal (N=20), and splenic (N=11)] were enrolled in this cohort. The median age was 67 years (range: 34 to 88 years), 52% were female, 83% were White, 7% were Black, 3% were Asian, 7% were Other, and 97% had a baseline ECOG performance status of 0 or 1. Patients had a median number of prior lines of therapy of 2 (range: 1 to 6), with 26% being refractory to their last therapy.

Efficacy was based on overall response rate as assessed by an Independent Review Committee (IRC) using criteria adopted from the International Working Group criteria for malignant lymphoma. The median follow-up time was 20.3 months (range: 15.0 to 28.7 months). Efficacy results are shown in Table 5.

Table 5: Efficacy Results in Patients with MZL (Study 205)

The median time to response was 2.8 months (range: 1.8 to 21.2 months). Overall response rates were 44.7%, 60.0%, and 45.5% for the 3 MZL sub-types (extranodal, nodal, and splenic, respectively).

Follicular Lymphoma

The efficacy of UKONIQ was evaluated in a single-arm cohort of Study UTX-TGR-205, an open-label, multi-center, multi-cohort trial (NCT02793583). Patients with relapsed or refractory FL were required to have received at least two prior systemic therapies, including an anti-CD20 monoclonal antibody and an alkylating agent. The trial excluded patients with Grade 3b FL, large cell transformation, prior allogeneic transplant, history of CNS lymphoma, and prior exposure to a PI3K inhibitor. Patients received UKONIQ 800 mg orally once daily until disease progression or unacceptable toxicity.

A total of 117 patients with FL were enrolled in this cohort. The median age was 65 years (range: 29 to 87 years), 38% were female, 80% were White, 4% were Black, 73% had Stage IIIIV disease, 38% had bulky disease and 97% had a baseline ECOG performance status of 0 to 1. Patients had a median of 3 prior lines of therapy (range: 1 to 10), with 36% refractory to their last therapy.

Efficacy was based on overall response rate as assessed by an Independent Review Committee (IRC) using criteria adopted from the International Working Group criteria for malignant lymphoma. The median follow-up time was 20.1 months (range: 13.5 to 29.6 months). Efficacy results are shown in Table 6.
