Clinical Pharmacology for Rinvoq
Mechanism Of Action
Upadacitinib is a Janus kinase (JAK) inhibitor. JAKs are intracellular enzymes which transmit signals arising from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoiesis and immune cell function. Within the signaling pathway, JAKs phosphorylate and activate signal transducers and activators of transcription (STATs) which modulate intracellular activity including gene expression. Upadacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs.
JAK enzymes transmit cytokine signaling through their pairing (e.g., JAK1/JAK2, JAK1/JAK3, JAK1/TYK2, JAK2/JAK2, JAK2/TYK2). In a cell-free isolated enzyme assay, upadacitinib had greater inhibitory potency at JAK1 and JAK2 relative to JAK3 and TYK2. In human leukocyte cellular assays, upadacitinib inhibited cytokine-induced STAT phosphorylation mediated by JAK1 and JAK1/JAK3 more potently than JAK2/JAK2 mediated STAT phosphorylation. The relevance of inhibition of specific JAK enzymes to therapeutic effectiveness is not currently known.
Pharmacodynamics
Inhibition Of IL-6 Induced STAT3 And IL-7 Induced STAT5 Phosphorylation
In healthy volunteers, the administration of upadacitinib (immediate release formulation) resulted in a dose-and concentration-dependent inhibition of IL-6 (JAK1/JAK2)-induced STAT3 and IL-7 (JAK1/JAK3)-induced STAT5 phosphorylation in whole blood. The maximal inhibition was observed 1 hour after dosing which returned to near baseline by the end of dosing interval.
Lymphocytes
In patients with rheumatoid arthritis, treatment with upadacitinib was associated with a small, transient increase in mean ALC from baseline up to Week 36 which gradually returned to, at or near baseline levels with continued treatment.
Immunoglobulins
In patients with rheumatoid arthritis, small decreases from baseline in mean IgG and IgM levels were observed with upadacitinib treatment in the controlled period; however, the mean values at baseline and at all visits were within the normal reference range.
Cardiac Electrophysiology
At 2.5 times the mean exposure of the maximum therapeutic dose, 45 mg once daily dose, there was no clinically relevant effect on the QTc interval.
Pharmacokinetics
Upadacitinib plasma exposures are proportional to dose over the therapeutic dose range. After a single dose administration of RINVOQ 15 mg, 30 mg, and 45 mg tablets under fasting condition in healthy subjects, mean Cmax was 31.6 ng/mL, 71.8 ng/mL, and 90.7 ng/mL, respectively, and mean AUCinf was 265 ng·h/mL, 543 ng·h/mL, and 752 ng·h/mL, respectively. Steady-state plasma concentrations are achieved within 4 days with minimal accumulation after once daily max is predicted to be 47.6 ng/mL and the mean steady-state AUC administration. Following the administration of the recommended pediatric dosage (Table 1, Table 2) in pJIA and psoriatic arthritis patients, the mean steady-state C0-24 is predicted to be 342 ng·h/mL. Upadacitinib pharmacokinetics are comparable between rheumatoid arthritis, psoriatic arthritis, atopic dermatitis, ulcerative colitis, Crohn's disease, ankylosing spondylitis, and non-radiographic axial spondyloarthritis and giant cell arteritis patients.
RINVOQ tablets and RINVOQ LQ are not bioequivalent; therefore, the 2 dosage forms are not interchangeable on a milligram-per-milligram basis [see DOSAGE AND ADMINISTRATION].
Absorption
Following oral administration of RINVOQ extended-release tablets, upadacitinib is absorbed with a median Tmax of 2 to 4 hours. Following oral administration of 6 mg RINVOQ LQ, upadacitinib is absorbed with a median Tmax of 1 hour.
Coadministration of RINVOQ tablets with a high-fat/high-calorie meal had no clinically relevant effect on upadacitinib exposures (increased AUCinf by 29% and Cmax by 39% to 60%). Coadministration of RINVOQ LQ with food is not expected to have a clinically relevant effect on upadacitinib exposure [see DOSAGE AND ADMINISTRATION].
Distribution
Upadacitinib is 52% bound to plasma proteins. Upadacitinib partitions similarly between plasma and blood cellular components with a blood to plasma ratio of 1.0.
Elimination
Metabolism
Upadacitinib metabolism is mediated by mainly CYP3A4 with a potential minor contribution from CYP2D6. The pharmacologic activity of upadacitinib is attributed to the parent molecule. In a human radiolabeled study, unchanged upadacitinib accounted for 79% of the total radioactivity in plasma while the main metabolite detected (product of monooxidation followed by glucuronidation) accounted for 13% of the total plasma radioactivity. No active metabolites have been identified for upadacitinib.
Excretion
Following single dose administration of [14C]-upadacitinib immediate-release solution, upadacitinib was eliminated predominantly as the unchanged parent drug in urine (24%) and feces (38%). Approximately 34% of upadacitinib dose was excreted as metabolites. Upadacitinib mean terminal elimination half-life ranged from 8 to 14 hours.
Specific Populations
Body Weight, Gender, And Race
Body weight, gender, race, and ethnicity did not have a clinically meaningful effect on upadacitinib exposure in adult patient populations.
Pediatric Patients
In pediatric patients with JIA with active polyarthritis, upadacitinib clearance increased with increasing body weight. Age (over the range of 2 to < 18 years old) had no additional effect on upadacitinib pharmacokinetics after accounting for the effect of body weight. Upadacitinib plasma exposures in pediatric patients with pJIA and psoriatic arthritis following the recommended pediatric dosage are predicted to be comparable to those observed in adult patients with rheumatoid arthritis and psoriatic arthritis, respectively.
No meaningful difference in the systemic exposure of upadacitinib was observed in pediatric patients with atopic dermatitis 12 years of age and older weighing at least 40 kg compared to adults.
Geriatric Patients
No clinically meaningful differences in the pharmacokinetics of upadacitinib were observed in geriatric patients (≥ 65 years of age) compared to younger adult patients.
Patients With Renal Impairment
Upadacitinib mean AUCinf after a single dose administration of 15 mg upadacitinib tablets was 18%, 33%, and 44% higher in patients with mild (eGFR 60 to < 90 mL/min/1.73 m²), moderate (eGFR 30 to < 60 mL/min/1.73 m²), and severe renal impairment (eGFR 15 to < 30 mL/min/1.73 m²), respectively, compared to subjects with normal renal function (eGFR m²≥ 90 mL/min/1.73 ). Upadacitinib mean Cmax was similar among subjects with normal and impaired renal function. In patients receiving RINVOQ/RINVOQ LQ, mild and moderate renal impairment is not expected to have a clinically relevant effect on upadacitinib exposure [see DOSAGE AND ADMINISTRATION and Use In Specific Populations].
Patients With Hepatic Impairment
Upadacitinib mean AUCinf after a single dose administration of 15 mg upadacitinib tablets was 28% and 24% higher in patients with mild (Child-Pugh A) and moderate (Child-Pugh B) hepatic impairment, respectively, compared to subjects with normal liver function. Upadacitinib mean Cmax was unchanged in patients with mild hepatic impairment and 43% higher in patients with moderate hepatic impairment compared to subjects with normal liver function. Upadacitinib was not studied in patients with severe hepatic impairment (Child-Pugh C) [see DOSAGE AND ADMINISTRATION and Use In Specific Populations].
Drug Interaction Studies
Potential For Other Drugs To Influence The Pharmacokinetics Of Upadacitinib
Upadacitinib is metabolized in vitro by CYP3A4 with a minor contribution from CYP2D6. The effect of co-administered drugs on upadacitinib plasma exposures is provided in Table 11 [see DRUG INTERACTIONS].

pH modifying medications (e.g., antacids or proton pump inhibitors) are not expected to affect upadacitinib plasma exposures based on in vitro assessments and population pharmacokinetic analyses. CYP2D6 metabolic phenotype had no effect on upadacitinib pharmacokinetics (based on population pharmacokinetic analyses), indicating that inhibitors of CYP2D6 have no clinically relevant effect on upadacitinib exposures.
Potential For Upadacitinib To Influence The Pharmacokinetics Of Other Drugs
In vitro studies indicate that upadacitinib does not inhibit the activity of cytochrome P450 (CYP) enzymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4) at clinically relevant concentrations. In vitro studies indicate that upadacitinib induces CYP3A4 but does not induce CYP2B6 or CYP1A2 at clinically relevant concentrations. In vitro studies indicate that upadacitinib does not inhibit the transporters P-gp, BCRP, OATP1B1, OATP1B3, OCT1, OCT2, OAT1, OAT3, MATE1, and MATE2K at clinically relevant concentrations.
Clinical studies indicate that upadacitinib has no clinically relevant effects on the pharmacokinetics of co-administered drugs. Following upadacitinib 30 mg and 45 mg tablets once daily, the effects on each CYP enzymes (CYP1A2, CYP3A, CYP2C9, and CYP2C19) were similar between two doses except for the effect on CYP2D6. Following upadacitinib 30 mg and 45 mg tablets once daily, a weak induction of CYP3A4 was observed. A weak inhibition of CYP2D6 was observed at upadacitinib 45 mg but not at 30 mg. Summary of results from clinical studies which evaluated the effect of upadacitinib on other drugs is provided in Table 12.

Clinical Studies
Rheumatoid Arthritis
The efficacy and safety of RINVOQ 15 mg once daily were assessed in five Phase 3 randomized, double-blind, multicenter trials in patients with moderately to severely active rheumatoid arthritis and fulfilling the ACR/EULAR 2010 classification criteria. Patients 18 years of age and older were eligible to participate. The presence of at least 6 tender and 6 swollen joints and evidence of systemic inflammation based on elevation of hsCRP was required at baseline. Although other doses have been studied, the recommended dosage of RINVOQ is 15 mg once daily.
Trial RA-I (NCT02706873) was a 24-week monotherapy trial in 947 patients with moderately to severely active rheumatoid arthritis who were naïve to methotrexate (MTX). Patients received RINVOQ 15 mg or upadacitinib 30 mg orally once daily or MTX as monotherapy. At Week 26, non-responding patients on upadacitinib could be rescued with the addition of MTX, while patients on MTX could be rescued with the addition of blinded RINVOQ 15 mg or upadacitinib 30 mg once daily. The primary endpoint was the proportion of patients who achieved an ACR50 response at Week 12. Key secondary endpoints included disease activity score (DAS28-CRP) ≤3.2 at Week 12, DAS28-CRP <2.6 at Week 24, change from baseline in HAQ-DI at Week 12, and change from baseline in van der Heijde-modified total Sharp Score (mTSS) at Week 24.
Trial RA-II (NCT02706951) was a 14-week monotherapy trial in 648 patients with moderately to severely active rheumatoid arthritis who had an inadequate response to MTX. Patients received RINVOQ 15 mg or upadacitinib 30 mg once daily monotherapy or continued their stable dose of MTX monotherapy. At Week 14, patients who were randomized to MTX were advanced to RINVOQ 15 mg or upadacitinib 30 mg once daily monotherapy in a blinded manner based on pre-determined assignment at baseline. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 14. Key secondary endpoints included DAS28-CRP ≤3.2, DAS28-CRP <2.6, and change from baseline in HAQ-DI at Week 14.
Trial RA-III (NCT02675426) was a 12-week trial in 661 patients with moderately to severely active rheumatoid arthritis who had an inadequate response to conventional disease modifying anti-rheumatic drugs (cDMARDs). Patients received RINVOQ 15 mg or upadacitinib 30 mg once daily or placebo added to background cDMARD therapy. At Week 12, patients who were randomized to placebo were advanced to RINVOQ 15 mg or upadacitinib 30 mg once daily in a blinded manner based on pre-determined assignment at baseline. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 12. Key secondary endpoints included DAS28-CRP ≤3.2, DAS28-CRP<2.6, and change from baseline in HAQ-DI at Week 12.
Trial RA-IV (NCT02629159) was a 48-week trial in 1629 patients with moderately to severely active rheumatoid arthritis who had an inadequate response to MTX. Patients received RINVOQ 15 mg once daily, active comparator, or placebo added to background MTX. From Week 14, non-responding patients on RINVOQ 15 mg could be rescued to active comparator in a blinded manner, and non-responding patients on active comparator or placebo could be rescued to RINVOQ 15 mg in a blinded manner. At Week 26, all patients randomized to placebo were switched to RINVOQ 15 mg once daily in a blinded manner. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 12 versus placebo. Key secondary endpoints versus placebo included DAS28-CRP ≤3.2, DAS28-CRP <2.6, change from baseline in HAQ-DI at Week 12, and change from baseline in mTSS at Week 26.
Trial RA-V (NCT02706847) was a 12-week trial in 499 patients with moderately to severely active rheumatoid arthritis who had an inadequate response or intolerance to biologic DMARDs. Patients received RINVOQ 15 mg or upadacitinib 30 mg once daily or placebo added to background cDMARD therapy. At Week 12, patients who were randomized to placebo were advanced to RINVOQ 15 mg or upadacitinib 30 mg once daily in a blinded manner based on pre-determined assignment at baseline. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 12. Key secondary endpoints included DAS28-CRP ≤3.2 and change from baseline in HAQ-DI at Week 12.
Clinical Response
The percentages of RINVOQ-treated patients achieving ACR20, ACR50, and ACR70 responses, and DAS28(CRP) < 2.6 in all trials are shown in Table 13.
Patients treated with RINVOQ 15 mg, alone or in combination with cDMARDs, achieved higher ACR response rates compared to MTX monotherapy or placebo, respectively, at the primary efficacy timepoint (Table 12).
In Trial IV, the percent of patients achieving ACR20 response by visit is shown in Figure 1.
In Trials RA-III and RA-V, higher ACR20 response rates were observed at 1 week with RINVOQ 15 mg versus placebo.
Treatment with RINVOQ 15 mg, alone or in combination with cDMARDs, resulted in greater improvements in the ACR components compared to MTX or placebo at the primary efficacy timepoint (Table 14).

Radiographic Response
Inhibition of progression of structural joint damage was assessed using the modified Total Sharp Score (mTSS) and its components, the erosion score and joint space narrowing score, at Week 26 in Trial RA-IV and Week 24 in Trial RA-I. The proportion of patients with no radiographic progression (mTSS change from baseline ≤ 0) was also assessed.
In Trial RA-IV, treatment with RINVOQ 15 mg inhibited the progression of structural joint damage compared to placebo in combination with cDMARDs at Week 26 (Table 16). Analyses of erosion and joint space narrowing scores were consistent with overall results.
In the placebo plus MTX group, 76% of the patients experienced no radiographic progression at Week 26 compared to 83% of the patients treated with RINVOQ 15 mg.
In Trial RA-I, treatment with RINVOQ 15 mg monotherapy inhibited the progression of structural joint damage compared to MTX monotherapy at Week 24 (Table 15). Analyses of erosion and joint space narrowing scores were consistent with overall results.
In the MTX monotherapy group, 78% of the patients experienced no radiographic progression at Week 24 compared to 87% of the patients treated with RINVOQ 15 mg monotherapy.

Physical Function Response
Treatment with RINVOQ 15 mg, alone or in combination with cDMARDs, resulted in a greater improvement in physical function at Week 12/14 compared to all comparators as measured by HAQ-DI.
Other Health-Related Outcomes
In all trials except for Trial RA-V, patients receiving RINVOQ 15 mg had greater improvement from baseline in physical component summary (PCS) score, mental component summary (MCS) scores, and in all 8 domains of the Short Form Health Survey (SF-36) compared to placebo in combination with cDMARDs or MTX monotherapy at Week 12/14.
Fatigue was assessed by the Functional Assessment of Chronic Illness Therapy-Fatigue score (FACIT-F) in Trials RA-I, RA-III, and RA-IV. Improvement in fatigue at Week 12 was observed in patients treated with RINVOQ 15 mg compared to patients on placebo in combination with cDMARDs or MTX monotherapy.
Psoriatic Arthritis
The efficacy and safety of RINVOQ 15 mg once daily were assessed in two Phase 3 randomized, double-blind, multicenter, placebo-controlled trials in patients 18 years of age or older with moderately to severely active psoriatic arthritis. All patients had active psoriatic arthritis for at least 6 months based upon the Classification Criteria for Psoriatic Arthritis (CASPAR), at least 3 tender joints and at least 3 swollen joints, and active plaque psoriasis or history of plaque psoriasis. Although another dose has been studied, the recommended dose of RINVOQ is 15 mg once daily for psoriatic arthritis.
Trial PsA-I (NCT03104400) was a 24-week trial in 1705 patients with moderately to severely active psoriatic arthritis who had an inadequate response or intolerance to at least one non-biologic DMARD. Patients received RINVOQ 15 mg or upadacitinib 30 mg once daily, adalimumab, or placebo, alone or in combination with background non-biologic DMARDs. At Week 24, all patients randomized to placebo were switched to RINVOQ 15 mg or upadacitinib 30 mg once daily in a blinded manner. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 12.
Trial PsA-II (NCT03104374) was a 24-week trial in 642 patients with moderately to severely active psoriatic arthritis who had an inadequate response or intolerance to at least one biologic DMARD. Patients received RINVOQ 15 mg or upadacitinib 30 mg once daily or placebo, alone or in combination with background non-biologic DMARDs. At Week 24, all patients randomized to placebo were switched to RINVOQ 15 mg or upadacitinib 30 mg once daily in a blinded manner. The primary endpoint was the proportion of patients who achieved an ACR20 response at Week 12.
Clinical Response
In both trials, patients treated with RINVOQ 15 mg achieved significantly higher ACR20 responses compared to placebo at Week 12 (Table 17, Figure 2). A higher proportion of patients treated with RINVOQ 15 mg achieved ACR50 and ACR70 responses at Week 12 compared to placebo.
Treatment with RINVOQ 15 mg resulted in improvements in the ACR components compared to placebo at the primary efficacy timepoint (Table 18).

Treatment with RINVOQ 15 mg resulted in improvement in dactylitis and enthesitis in patients with pre-existing dactylitis or enthesitis.
Treatment with RINVOQ 15 mg resulted in improvement in skin manifestations in patients with PsA. However, RINVOQ has not been studied in and is not indicated for the treatment of plaque psoriasis.
Physical Function Response
In both trials, patients treated with RINVOQ 15 mg showed significant improvement in physical function from baseline compared to placebo as assessed by HAQ-DI at Week 12 (Table 16). The mean difference (95% CI) from placebo in HAQ-DI change from baseline at Week 12 was -0.28 (-0.35, -0.22) in Trial PsA-I and -0.21 (-0.30, -0.12) in Trial PsA-II.
The proportion of HAQ-DI responders (≥ 0.35 improvement from baseline in HAQ-DI score) at Week 12 in Trial PsA-I and Trial PsA-II was 58% and 45%, respectively, in patients receiving RINVOQ 15 mg and 33% and 27%, respectively, in patients receiving placebo.
Radiographic Response
In Trial PsA-I, inhibition of progression of structural damage was assessed radiographically and expressed as the change from baseline in modified Total Sharp Score (mTSS) and its components, the erosion score and the joint space narrowing score, at Week 24.
Treatment with RINVOQ 15 mg inhibited progression of structural joint damage compared to placebo at Week 24 (Table 19). Analyses of erosion and joint space narrowing scores were consistent with overall results. The proportion of patients with no radiographic progression (mTSS change ≤ 0) at Week 24 was 93% in patients receiving RINVOQ 15 mg and 89% in patients receiving placebo.

Other Health-Related Outcomes
Health-related quality of life was assessed by SF-36. In both trials, patients receiving RINVOQ 15 mg experienced significantly greater improvement from baseline in the Physical Component Summary score compared to placebo at Week 12. Greater improvement was also observed in the Mental Component Summary score and all 8 domains of SF-36 compared to placebo.
Patients receiving RINVOQ 15 mg showed greater improvement from baseline in fatigue, as measured by FACIT-F score, at Week 12 compared to placebo in both trials.
Atopic Dermatitis
The efficacy of RINVOQ 15 mg and 30 mg once daily, was assessed in three Phase 3 randomized, double-blind, multicenter trials (AD-1, AD-2, AD-3; NCT03569293, NCT03607422, and NCT03568318, respectively) in a total of 2584 patients (12 years of age and older). RINVOQ was evaluated in 344 pediatric patients and 2240 adult patients with moderate to severe atopic dermatitis (AD) not adequately controlled by topical medication(s).
Disease severity at baseline was defined by a validated Investigator's Global Assessment (vIGA-AD) score ≥3 in the overall assessment of AD on a severity scale of 0 to 4, an Eczema Area and Severity Index (EASI) score ≥16, a minimum body surface area (BSA) involvement of ≥10%, and weekly average Worst Pruritus Numerical Rating Scale (NRS) score ≥4. Overall, 57% of the patients were male and 69% were white. The mean age at baseline was 34 years (ranged from 12 to 75 years) and 13% of the patients were 12 to less than 18 years. At baseline, 49% of patients had a vIGA-AD score of 3 (moderate AD), and 51% of patients had a vIGA-AD score of 4 (severe AD). The baseline mean EASI score was 29 and the baseline weekly average Worst Pruritus NRS score was 7. Approximately 52% of the patients had prior exposure to systemic AD treatment.
In all three trials, patients received RINVOQ once daily oral doses of 15 mg, 30 mg, or matching placebo for 16 weeks. In Trial AD-3, patients also received RINVOQ or placebo with concomitant topical corticosteroids (TCS) for 16 weeks.
All three trials assessed the co-primary endpoints of the proportion of patients with a vIGA-AD score of 0 (clear) or 1 (almost clear) with at least a 2-point improvement and the proportion of patients with EASI-75 (improvement of at least 75% in EASI score from baseline) at Week 16. Secondary endpoints included EASI-90 and EASI-100 at Week 16, and the proportion of patients with reduction in itch (≥4-point improvement from baseline in the Worst Pruritus NRS) at Weeks 1, 4, and 16. In Trials AD-1 and AD-2, the proportion of patients with reduction in pain (≥4Âpoint improvement in the Atopic Dermatitis Symptom Scale [ADerm-SS] Skin Pain NRS) from baseline to Week 16 was a secondary endpoint.

Ulcerative Colitis
Induction Trials (Study UC-1 And Study UC-2)
In two identical induction trials (UC-1; NCT02819635 and UC-2; NCT03653026), patients were randomized 2:1 to receive either RINVOQ 45 mg once daily or placebo for 8 weeks. A total of 988 patients were analyzed across the two trials. These trials included adult patients with moderately to severely active ulcerative colitis who had an inadequate response, loss of response, or intolerance to oral aminosalicylates, corticosteroids, immunosuppressants, and/or biologic therapy. Enrolled patients were permitted to use stable doses of oral aminosalicylates, methotrexate, ulcerative colitis-related antibiotics, and/or oral corticosteroids (up to 30 mg/day prednisone or equivalent). At baseline, 38% of patients were receiving corticosteroids, and 68% of patients were receiving aminosalicylates. Concomitant biologic therapies, azathioprine, 6Âmercaptopurine, intravenous or rectal corticosteroids were prohibited. A total of 51% of patients had previously failed treatment with or were intolerant to at least one biologic therapy. RINVOQ is indicated for patients who have an inadequate response or intolerance to one or more TNF blockers [see INDICATIONS AND USAGE].
Disease activity was assessed on the modified Mayo score (mMS), a 3-component Mayo score (0-9) which consists of the following subscores (0 to 3 for each subscore): stool frequency (SFS), rectal bleeding (RBS), and findings on centrally read endoscopy score (ES). An ES of 2 was defined by marked erythema, lack of vascular pattern, any friability, and/or erosions, and a score of 3 was defined by spontaneous bleeding and ulceration. Enrolled patients had a mMS between 5 to 9 with an ES of 2 or 3; at baseline the median mMS was 7, with 61% of patients having a baseline mMS of 5 to 7 and 39% having a mMS of 8 to 9.
At baseline, 39% and 37% of patients received corticosteroids, 1% and 1% of patients received methotrexate, and 68% and 69% of patients received aminosalicylates in UC-1 and UC-2, respectively. Patient disease activity was moderate (mMS ≤7) in 61% and 60% of patients and severe (mMS >7) in 39% and 40% of patients in UC-1 and UC-2, respectively.
The primary endpoint was clinical remission defined using the mMS at Week 8. Secondary endpoints included clinical response, endoscopic improvement, and histologic endoscopic mucosal improvement (see Table 24 and Table 25).

Studies UC-1 and UC-2 were not designed to evaluate the relationship of histologic endoscopic mucosal improvement at Week 8 to disease progression and long-term outcomes.
Rectal Bleeding And Stool Frequency Subscores
Onset of clinical response was assessed using the SFS and RBS (partial modified Mayo Score [pmMS]). Initial response was defined as a decrease of ≥1 point and ≥30% from baseline in pmMS and a decrease in RBS ≥1 or an absolute RBS≤1. Onset of response occurred as early as Week 2 in a greater proportion of patients treated with RINVOQ 45 mg once daily compared to placebo.
Endoscopic And Histologic Assessment
Normalization of the endoscopic appearance of the mucosa (endoscopic remission) was defined as ES of 0. At Week 8, a greater proportion of patients treated with RINVOQ 45 mg once daily compared to placebo achieved endoscopic remission (UC-1: 14% vs 1%, UC-2: 18% vs 2%). Endoscopic remission with Geboes histologic score < 2.0 (indicating no neutrophils in crypts or lamina propria and no increase in eosinophil, no crypt destruction, and no erosions, ulcerations, or granulation tissue) was achieved by a greater proportion of patients treated with RINVOQ 45 mg once daily compared to placebo at Week 8 (UC-1: 11% vs 1%, UC-2: 13% vs 2%).
Abdominal Pain And Bowel Urgency
A greater proportion of patients treated with RINVOQ 45 mg once daily compared to placebo had no abdominal pain (UC-1: 47% vs 23%, UC-2: 54% vs 24%) and no bowel urgency (UC-1: 48% vs 21%, UC-2: 54% vs 26%) at Week 8.
Fatigue
In Studies UC-1 and UC-2, patients treated with RINVOQ experienced a clinically meaningful improvement in fatigue, as assessed by change from baseline in FACIT-F score, at Week 8, compared to placebo-treated patients. The effect of RINVOQ to improve fatigue after 8 weeks of induction has not been established.
Maintenance Study UC-3
In UC-3 (NCT02819635), a total of 451 patients who received RINVOQ 45 mg once daily in either UC-1, UC-2 or UC-4 and achieved clinical response were re-randomized to receive RINVOQ 15 mg, 30 mg or placebo once daily for up to 52 weeks.
The primary endpoint was clinical remission defined using mMS at Week 52. Secondary endpoints included corticosteroid-free clinical remission, endoscopic improvement, and histologic endoscopic mucosal improvement (see Table 26).

The relationship between histologic endoscopic mucosal improvement at Week 52 and disease progression and longer-term outcomes after Week 52 was not evaluated in Study UC-3.
Endoscopic And Histologic Assessment
Normalization of the endoscopic appearance of the mucosa (endoscopic remission) was defined as ES of 0. In UC-3, a greater proportion of patients treated with RINVOQ 15 mg and 30 mg once daily compared to placebo achieved endoscopic remission at Week 52 (24% and 26% vs 6%). Endoscopic remission with Geboes histologic score < 2.0 was achieved by a greater proportion of patients treated with RINVOQ 15 mg and 30 mg once daily compared to placebo at Week 52 (18% and 19% vs 5%).
Abdominal Pain And Bowel Urgency
At Week 52, a greater proportion of patients treated with RINVOQ 15 mg and 30 mg once daily compared to placebo had no abdominal pain (46%, 55% and 21%, respectively) and no bowel urgency (56%, 64% and 17%, respectively).
Crohn's Disease
Induction Trials (Studies CD-1 And CD-2)
In two induction trials, CD-1 (NCT03345836) and CD-2 (NCT03345849), patients were randomized 2:1 to receive RINVOQ 45 mg or placebo once daily for 12 weeks. Efficacy was assessed in a population of 857 patients (419 patients in CD-1 and 438 patients in CD-2) with moderately to severely active Crohn's disease (CD), with baseline Crohn's Disease Activity Index (CDAI) score of at least 220 and centrally-reviewed Simple Endoscopic Score for Crohn's Disease (SES-CD) of ≥ 6, or ≥ 4 for isolated ileal disease, excluding the narrowing component. In CD-1, all patients had inadequate response or were intolerant to treatment with one or more biological therapies (prior biologic failure). In CD-2, 45% (197/438) of patients had inadequate response or were intolerant to treatment with one or more biological therapies (prior biologic failure). Enrolled patients in both studies were permitted to use stable doses of CD-related antibiotics, aminosalicylates, or methotrexate. Concomitant corticosteroids (up to 30 mg/day prednisone or equivalent) were permitted at enrollment; tapering was initiated at Week 4.
In CD-1, patients had a mean age of 37 years (range 18 to 74 years); 46% were female; and 72% identified as White, 21% as Asian, 6% as Black or African American, 0.5% as American Indian or Alaska Native, and 0.5% as multiple racial groups. In CD-2, patients had a mean age of 40 years (range of 18 to 74 years); 45% were female; 74% identified as White, 20% as Asian, 4% as Black or African American, and 2% as multiple racial groups.
At baseline, 36% and 37% of patients received corticosteroids, 7% and 3% of patients received methotrexate, 15% and 24% of patients received aminosalicylates, and 2% and 1% of patients received CD-related antibiotics in CD-1 and CD-2, respectively.
The co-primary endpoints were the proportion of patients achieving clinical remission (by CDAI) at Week 12, and the proportion of patients achieving endoscopic response (by SES-CD) at Week 12. Secondary efficacy endpoints included clinical response, corticosteroid-free remission, and endoscopic remission (see Table 27 and Table 28).

Onset of clinical response based on CDAI was observed as early as two weeks in Studies CD-1 and CD-2, with a greater proportion of patients achieving clinical response at Week 2 in RINVOQ-treated patients compared with placebo.
In Studies CD-1 and CD-2, reductions in stool frequency and abdominal pain were observed in a greater proportion of patients treated with RINVOQ 45 mg induction regimen compared to placebo at Week 12.
In Studies CD-1 and CD-2, patients treated with RINVOQ experienced a clinically meaningful improvement in fatigue, assessed by change from baseline in FACIT-F score, at Week 12, compared to placebo-treated patients. The effect of RINVOQ to improve fatigue after 12 weeks of induction has not been established.
Maintenance Study (CD-3)
The efficacy analysis for CD-3 (NCT03345823) evaluated 343 patients who responded to 12 weeks of RINVOQ 45 mg once daily induction treatment. Patients were re-randomized to receive a maintenance regimen of either RINVOQ 15 mg or 30 mg once daily or placebo for 52 weeks, representing a total of at least 64 weeks of therapy.
The co-primary endpoints of clinical remission (by CDAI) and endoscopic response (by SES-CD) were assessed at Week 52. Secondary efficacy endpoints included corticosteroid-free clinical remission, maintenance of clinical remission, endoscopic remission, and achieving both clinical and endoscopic remission, at Week 52 (see Table 29).

Ankylosing Spondylitis
The efficacy and safety of RINVOQ 15 mg once daily were assessed in two randomized, double-blind, multicenter, placebo-controlled trials in patients 18 years of age or older with active ankylosing spondylitis based upon the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥4 and Patient's Assessment of Total Back Pain score ≥4.
Trial AS-I (NCT03178487) was a 14-week trial in 187 ankylosing spondylitis patients with an inadequate response to at least two nonsteroidal anti-inflammatory drugs (NSAIDs) or intolerance to or contraindication for NSAIDs and had no previous exposure to biologic DMARDs. At baseline, patients had symptoms of ankylosing spondylitis for an average of 14.4 years and approximately 16% of the patients were on a concomitant cDMARD. Patients received RINVOQ 15 mg once daily or placebo. At Week 14, all patients randomized to placebo were switched to RINVOQ 15 mg once daily. The primary endpoint was the proportion of patients achieving an Assessment of SpondyloArthritis international Society 40 (ASAS40) response at Week 14.
Trial AS-II (NCT 04169373) was a 14-week trial in 420 ankylosing spondylitis patients with an inadequate response to 1 or 2 biologic DMARDs. At baseline, patients had symptoms of ankylosing spondylitis for an average of 12.8 years and approximately 31% of the patients were on a concomitant cDMARD. Patients received RINVOQ 15 mg once daily or placebo. At Week 14, all patients randomized to placebo were switched to RINVOQ 15 mg once daily. The primary endpoint was the proportion of patients achieving an Assessment of SpondyloArthritis international Society 40 (ASAS40) response at Week 14.
Clinical Response
In both trials, a significantly greater proportion of patients treated with RINVOQ 15 mg achieved an ASAS40 response compared to placebo at Week 14 (Table 30, Figure 5).
Examination of gender, baseline body mass index (BMI), and baseline hsCRP did not identify differences in response to RINVOQ among these subgroups at Week 14.

Other Health-Related Outcomes
In Trial AS-II, patients treated with RINVOQ 15 mg showed significant improvements in health-related quality of life as measured by Ankylosing Spondylitis Quality of Life (ASQoL) compared to placebo at Week 14. In Trial AS-I, improvement in ASQoL compared to placebo was also observed.
Enthesitis
In Trial AS-II, patients with pre-existing enthesitis treated with RINVOQ 15 mg showed significant improvement in enthesitis compared to placebo as measured by change from baseline in Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) at Week 14. In Trial AS-I, improvement in MASES compared to placebo was also observed.
Spinal mobility
In Trial AS-II, patients treated with RINVOQ 15 mg showed significant improvement in spinal mobility compared to placebo as measured by change from baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI) at Week 14. In Trial AS-I, improvement in BASMI compared to placebo was also observed.
Non-radiographic Axial Spondyloarthritis
The efficacy and safety of RINVOQ 15 mg once daily were assessed in a randomized, double-blind, multicenter, placebo-controlled trial in patients 18 years of age or older with active non- radiographic axial spondyloarthritis. Trial nr-axSpA (NCT04169373) was a 52-week placebo-controlled trial in 314 patients (of which 313 patients received study treatment) with active non-radiographic axial spondyloarthritis with an inadequate response to at least two nonsteroidal anti-inflammatory drugs (NSAIDs) or intolerance to or contraindication for NSAIDs. Patients must have had objective signs of inflammation indicated by elevated C-reactive protein (CRP) (defined as > upper limit of normal), and/or sacroiliitis on magnetic resonance imaging (MRI), and no definitive radiographic evidence of structural damage on sacroiliac joints. Patients had active disease as defined by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥4, and a Patient's Assessment of Total Back Pain score ≥ 4 based on a 0-10 numerical rating scale (NRS) at the Screening and Baseline Visits. At baseline, approximately 29.1% of the patients were on a concomitant cDMARD. 32.9% of the patients had an inadequate response or intolerance to bDMARD therapy. Patients received RINVOQ 15 mg once daily or placebo. The primary endpoint was the proportion of patients achieving an Assessment of SpondyloArthritis international Society 40 (ASAS40) response at Week 14.
Clinical Response
In Trial nr-axSpA, a significantly greater proportion of patients treated with RINVOQ 15 mg achieved an ASAS40 response compared to placebo at Week 14 (Table 32, Figure 6).
Examination of gender, baseline BMI, symptom duration of non-radiographic axial spondyloarthritis, baseline hsCRP, MRI sacroiliitis, and prior use of bDMARDs did not identify differences in response to RINVOQ among these subgroups at Week 14.

Other Health-Related Outcomes
Patients treated with RINVOQ 15 mg showed significant improvements in health-related quality of life as measured by Ankylosing Spondylitis Quality of Life (ASQoL) compared to placebo at Week 14.
Polyarticular Juvenile Idiopathic Arthritis
The efficacy of RINVOQ/RINVOQ LQ in pediatric patients with JIA with active polyarthritis is based on exposure-matched extrapolation of the established efficacy of RINVOQ in rheumatoid arthritis patients. Safety and efficacy of RINVOQ/RINVOQ LQ were also assessed in a multicenter, open-label, single-arm study in 83 children (2 to < 18 years of age) with JIA with active polyarthritis (NCT03725007). The pJIA patient subtypes at study entry included rheumatoid factor negative polyarticular (68.7%), rheumatoid factor positive polyarticular (15.7%), extended oligoarticular (13.3%), and systemic JIA without systemic manifestations (2.4%). All patients received RINVOQ LQ or RINVOQ tablet dosages based on weight for up to 156 weeks. Patients treated with a stable dose of MTX were permitted to enter the study; changes in MTX dose were permitted during the study. Efficacy was assessed as supportive endpoints through Week 48. The efficacy was generally consistent with responses in patients with rheumatoid arthritis.
Giant Cell Arteritis
The efficacy and safety of RINVOQ 15 mg once daily were assessed in Trial GCA (NCT03725202), a Phase 3 randomized, double-blind, multicenter, placebo-controlled study in patients 50 years of age and older (81.8% were 65 years of age and older, 73.1% were female, 93.7% white) with new-onset or relapsing giant cell arteritis. Trial GCA was a 52-week trial in which 428 patients were randomized in a 2:1:1 ratio and dosed once daily with RINVOQ 15 mg, upadacitinib 7.5 mg, or placebo. All patients received background corticosteroid therapy. The RINVOQ and upadacitinib-treated groups followed a pre-specified corticosteroid taper regimen with the aim to reach 0 mg by 26 weeks, while the placebo-treated group followed a pre- specified corticosteroid taper regimen with the aim to reach 0 mg by 52 weeks. The primary endpoint was the proportion of patients achieving sustained remission at Week 52 as defined by the absence of giant cell arteritis signs and symptoms from Week 12 through Week 52 and adherence to the protocol-defined corticosteroid taper regimen. A key secondary endpoint was the proportion of patients achieving sustained complete remission at Week 52 as defined by the absence of giant cell arteritis signs and symptoms from Week 12 through Week 52, normalization of erythrocyte sedimentation rate and hsCRP from Week 12 through Week 52, and adherence to the protocol-defined corticosteroid taper regimen. The study included a 52-week extension for a total study duration of up to 2 years.
Clinical Response
RINVOQ 15 mg and a 26-week corticosteroid taper showed superiority in achieving corticosteroid-free sustained remission at Week 52 compared to placebo and a 52-week corticosteroid taper (Table 34).

Cumulative Corticosteroid Dose
The total actual cumulative corticosteroid dose was lower in the RINVOQ 15 mg and a 26-week corticosteroid taper arm (mean [SD] 2283.9 [1840.0] mg and median 1615 mg) relative to the placebo and a 52-week corticosteroid taper arm (mean [SD] 3388.3 [1463.1] mg and median 2882 mg).
