European Commission Approves RINVOQ® for the Treatment of Adults With Moderate to Severe Ulcerative Colitis

• RINVOQ (upadacitinib) is now approved by the European Commission for the treatment of adult patients with moderately to severely active ulcerative colitis who have had an inadequate response, lost response or were intolerant to either conventional therapy or a biologic agent ¹
• The approval is based on the results of three Phase 3 studies: two for induction and one for maintenance ^1,2
• In these clinical trials, RINVOQ achieved the primary endpoint of clinical remission (per Adapted Mayo Score) at week 8 in induction studies and week 52 in the maintenance study, and all secondary endpoints, including clinical response and mucosal healing ^1,2
• Safety results in ulcerative colitis were generally consistent with the known safety profile of RINVOQ, with no new important safety risks observed ^2,3-6
• Ulcerative colitis is a chronic, immune-mediated inflammatory bowel disease (IBD) that can lead to substantial burden and often disability among patients.   ^7-9   At least 6.8 million people worldwide live with IBD, including ulcerative colitis ¹⁰
• The approval represents RINVOQ's fifth therapeutic indication in the EU

ABBVie (NYSE: ABBV) today announced the European Commission (EC) approved RINVOQ® (upadacitinib 45 mg [induction dose] and 15 mg and 30 mg [maintenance doses]) for the treatment of adult patients with moderately to severely active ulcerative colitis who have had an inadequate response, lost response or were intolerant to either conventional therapy or a biologic agent.*

"Our years of experience and long-term investment in IBD research have given us invaluable insights into the challenges that ulcerative colitis patients face, and a deep understanding of the ongoing need for additional treatment options to help those still suffering," said Thomas Hudson , M.D., senior vice president, research and development, chief scientific officer, AbbVie. "We celebrate today's approval of RINVOQ by the EC as it meaningfully expands our ability to help indicated patients in need of relief from ulcerative colitis."

The EC approval is supported by data from two induction studies, U-ACHIEVE induction and U-ACCOMPLISH, and one maintenance study, U-ACHIEVE maintenance. ² Statistical significance was achieved for the primary endpoint and all secondary endpoints with RINVOQ 45 mg in the two induction studies and both RINVOQ 15 mg and 30 mg in the maintenance study.

Clinical Remission†

• During the U-ACHIEVE and U-ACCOMPLISH induction trials, 26 percent and 33 percent of patients treated with RINVOQ 45 mg achieved clinical remission at week 8, the primary endpoint, compared to 5 percent and 4 percent of patients who received placebo. ^2,11,12
• During the U-ACHIEVE maintenance trial, 42 percent and 52 percent of patients treated with RINVOQ 15 mg or 30 mg, respectively, achieved clinical remission at week 52, the primary endpoint, compared to 12 percent of patients who received placebo. ^2,13
• Additionally, 57 percent and 68 percent of patients receiving RINVOQ 15 mg or 30 mg, respectively, achieved corticosteroid-free remission, defined as clinical remission (per Adapted Mayo Score) and corticosteroid free for ≥90 days immediately preceding week 52 among patients who achieved clinical remission at the end of the induction treatment, compared to 22 percent of patients on placebo. ^2,13

Clinical Response & Mucosal Healing‡§

• Seventy-three and 74 percent of patients treated with RINVOQ 45 mg achieved clinical response (per Adapted Mayo Score) at week 8 compared to 27 and 25 percent of patients receiving placebo during the U-ACHIEVE and U-ACCOMPLISH induction trials, respectively. ^1,2,11,12,14
• In both trials, a significantly greater proportion of patients experienced clinical response per partial Adapted Mayo Score (symptomatic response) as early as week 2 (U-ACHIEVE: 60 percent vs 27 percent and U-ACCOMPLISH: 63 percent vs 26 percent). ^1,2,11,12,14
• Mucosal healing was observed in 36 percent and 44 percent of patients treated with RINVOQ 45 mg in U-ACHIEVE and U- ACCOMPLISH, respectively, at week 8, compared to 7 percent and 8 percent of patients, respectively, who received placebo. ^1,2
• In the maintenance study at week 52, mucosal healing was observed in 49 percent and 62 percent of patients treated with RINVOQ 15 mg and 30 mg, respectively, compared to 14 percent who received placebo. ^1,2,13

"Patients with ulcerative colitis live with unpredictable, often painful symptoms that significantly impact their quality of life, including emotional, social and economic impacts," said Séverine Vermeire, M.D., Ph.D., professor of gastroenterology at University Hospital Leuven in Leuven, Belgium . "RINVOQ demonstrated the ability to help patients experience improvements in disease parameters such as durable clinical remission and mucosal healing at week eight of induction therapy and week 52 of maintenance therapy. These results represent an exciting possibility for patients who continue to experience active disease despite treatment with conventional or biologic therapy."

In the placebo-controlled ulcerative colitis induction and maintenance clinical trials, the overall safety findings were generally consistent with the known safety profile of upadacitinib; no new important safety risks were observed. ¹ The rates of overall adverse events (AE), serious AEs, and AEs resulting in treatment discontinuation were lower with upadacitinib compared to placebo. ¹ The most commonly reported adverse reactions (≥5 percent of patients) with RINVOQ 45 mg, 30 mg or 15 mg were upper respiratory tract infection, blood CPK increased, acne, neutropaenia, and rash. ¹ In the overall clinical program, major cardiovascular events, thrombotic events, malignancy excluding non-melanoma skin cancer, and gastrointestinal perforation were reported infrequently (all 1

About the U-ACHIEVE Induction, U-ACCOMPLISH and U-ACHIEVE Maintenance Studies ^2,6,15,16

The three Phase 3 studies are multicenter, randomized, double-blind, placebo-controlled studies to evaluate the efficacy and safety of RINVOQ 45 mg once daily as induction therapy, and RINVOQ 15 mg and 30 mg once daily as maintenance therapy in subjects with moderate to severe ulcerative colitis. The results of these studies were published in The Lancet in May 2022 . More information can be found on https://www.clinicaltrials.gov (NCT03006068, NCT03653026, NCT02819635).

About RINVOQ® (upadacitinib)

Discovered and developed by AbbVie scientists, RINVOQ is a selective and reversible JAK inhibitor that is being studied in several immune-mediated inflammatory diseases. ^{1,2,3-6,17,18} In human cellular assays, RINVOQ preferentially inhibits signalling by JAK1 or JAK1/3 with functional selectivity over cytokine receptors that signal via pairs of JAK2. ¹

Phase 3 trials of RINVOQ in rheumatoid arthritis, atopic dermatitis, psoriatic arthritis, axial spondyloarthritis, Crohn's disease, ulcerative colitis, giant cell arteritis and Takayasu arteritis are ongoing. ^4-6,15-22

EU Indications and Important Safety Information about RINVOQ® (upadacitinib) ¹

Indications

Ulcerative colitis

RINVOQ is indicated for the treatment of adult patients with moderately to severely active ulcerative colitis (UC) who have had an inadequate response, lost response or were intolerant to either conventional therapy or a biologic agent.

Rheumatoid arthritis

RINVOQ is indicated for the treatment of moderate to severe active rheumatoid arthritis (RA) in adult patients who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs (DMARDs). RINVOQ may be used as monotherapy or in combination with methotrexate.

Psoriatic arthritis

RINVOQ is indicated for the treatment of active psoriatic arthritis (PsA) in adult patients who have responded inadequately to, or who are intolerant to one or more DMARDs. RINVOQ may be used as monotherapy or in combination with methotrexate.

Ank y losing spondylitis

RINVOQ is indicated for the treatment of active ankylosing spondylitis (AS) in adult patients who have responded inadequately to conventional therapy.

Atopic dermatitis

RINVOQ is indicated for the treatment of moderate to severe atopic dermatitis (AD) in adults and adolescents 12 years and older who are candidates for systemic therapy.

Important Safety Information

Contraindications

RINVOQ is contraindicated in patients hypersensitive to the active substance or to any of the excipients, in patients with active tuberculosis (TB) or active serious infections, in patients with severe hepatic impairment, and during pregnancy.

Special warnings and precautions for use

Immunosuppressive   medicinal   products

Use in combination with other potent immunosuppressants is not recommended.

Serious infections

Serious and sometimes fatal infections have been reported in patients receiving upadacitinib. The most frequent serious infections reported included pneumonia and cellulitis. Cases of bacterial meningitis have been reported. Among opportunistic infections, TB, multidermatomal herpes zoster, oral/esophageal candidiasis, and cryptococcosis have been reported with upadacitinib. As there is a higher incidence of infections in patients ≥65 years of age, caution should be used when treating this population. Upadacitinib should be interrupted if a patient develops serious or opportunistic infection.

Tuberculosis

Patients should be screened for TB before starting RINVOQ. RINVOQ should not be given to patients with active TB. Anti-TB therapy may be appropriate for select patients in consultation with a physician with expertise in the treatment of TB. Patients should be monitored for the development of signs and symptoms of TB.

Viral reactivation

Viral reactivation, including cases of herpes zoster, was reported in clinical studies. The risk of herpes zoster appears to be higher in Japanese patients treated with upadacitinib. Consider interruption of upadacitinib if patient develops herpes zoster.

Vaccinations

The use of live, attenuated vaccines during or immediately prior to therapy is not recommended. It is recommended that patients be brought up to date with all immunizations, including prophylactic zoster vaccinations, prior to initiating upadacitinib, in agreement with current immunization guidelines.

Malignancy

The risk of malignancies, including lymphoma is increased in patients with rheumatoid arthritis. Malignancies, including nonmelanoma skin cancer (NMSC), have been reported in patients treated with upadacitinib. Consider the risks and benefits of upadacitinib treatment prior to initiating therapy in patients with a known malignancy other than a successfully treated NMSC or when considering continuing upadacitinib therapy in patients who develop a malignancy. Periodic skin examination is recommended for patients who are at increased risk for skin cancer.

Hematological abnormalities

Treatment should not be initiated, or should be temporarily interrupted, in patients with hematological abnormalities observed during routine patient management.

Diverticulitis

Upadacitinib should be used with caution in patients with diverticular disease and especially in patients chronically treated with concomitant medications associated with an increased risk of diverticulitis.

Cardiovascular   risk

RA patients have an increased risk for cardiovascular disorders. Patients treated with upadacitinib should have risk factors (e.g., hypertension, hyperlipidemia) managed as part of usual standard of care.

Lipids

Upadacitinib treatment was associated with dose-dependent increases in lipid parameters, including total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol.

Hepatic transaminase elevations

Treatment with upadacitinib was associated with an increased incidence of liver enzyme elevation compared to placebo. If alanine transaminase (ALT) or aspartate transaminase (AST) increases are observed and drug-induced liver injury is suspected, upadacitinib should be interrupted until the diagnosis is excluded.

Venous   thromboembolisms

Events of deep vein thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients receiving JAK inhibitors, including upadacitinib. Upadacitinib should be used with caution in patients at high risk for DVT/PE. If DVT/PE occur, upadacitinib should be discontinued and patients should be evaluated and treated appropriately.

Elderly

There is an increased risk of adverse reactions with the upadacitinib dose of 30 mg once daily in patients aged 65 years and older. The recommended dose for long-term use is 15 mg once daily for this patient population.

Adverse reactions

The most commonly reported adverse reactions in RA, PsA, and AS clinical trials (≥2% of patients in at least one of the indications) with upadacitinib 15 mg were upper respiratory tract infections, blood creatine phosphokinase (CPK) increased, alanine transaminase (ALT) increased, bronchitis, nausea, cough, aspartate transaminase (AST) increased, and hypercholesterolemia. Overall, the safety profile observed in patients with psoriatic arthritis or active ankylosing spondylitis treated with upadacitinib 15 mg was consistent with the safety profile observed in patients with RA.

The most commonly reported adverse reactions in atopic dermatitis trials (≥2% of patients) with upadacitinib 15 mg or 30 mg were upper respiratory tract infection, acne, herpes simplex, headache, CPK increased, cough, folliculitis, abdominal pain, nausea, neutropenia, pyrexia, and influenza. Dose-dependent increased risks of serious infection and herpes zoster were observed with upadacitinib. The safety profile for upadacitinib 15 mg in adolescents was similar to that in adults. The safety and efficacy of the 30 mg dose in adolescents are still being investigated.

The most commonly reported adverse reactions in UC trials (≥3% of patients) with upadacitinib 45 mg, 30 mg or 15 mg were upper respiratory tract infection, blood CPK increased, acne, neutropaenia, rash, herpes zoster, hypercholesterolemia, folliculitis, herpes simplex, and influenza. The overall safety profile observed in patients with ulcerative colitis was generally consistent with that observed in patients with RA.

The most common serious adverse reactions were serious infections.

The safety profile of upadacitinib with long term treatment was generally similar to the safety profile during the placebo-controlled period across indications.
