AbbVie (NYSE: ABBV) today announced The Lancet published results from three pivotal Phase 3 clinical trials – ADVANCE, MOTIVATE (induction studies) and FORTIFY (maintenance study) – evaluating risankizumab (SKYRIZI®) in patients with moderately to severely active Crohn’s disease who have had inadequate response, lost response or were intolerant to conventional or biologic therapy.
Data from the three studies formed the basis of the company’s application for approval by the global health authorities. The publication of ADVANCE and MOTIVATE reports the efficacy and safety results of the two induction studies evaluating clinical remission and endoscopic response with intravenous (IV) risankizumab versus placebo over 12 weeks.1 The publication of FORTIFY shares the results of the maintenance study evaluating the safety and efficacy of subcutaneous (SC) risankizumab versus placebo (the withdrawal from IV risankizumab) over 52 weeks in patients who achieved clinical response during the ADVANCE and MOTIVATE studies.2
The use of risankizumab for Crohn’s disease is not approved and its safety and efficacy remain under regulatory review.
About Crohn’s Disease
Crohn’s disease is a chronic, systemic disease that manifests as inflammation within the gastrointestinal (or digestive) tract, causing persistent diarrhea and abdominal pain.3,4,5 It is a progressive disease, meaning it gets worse over time in a substantial proportion of patients.2,3 Because the signs and symptoms of Crohn’s disease are unpredictable, it causes a significant burden on people living with the disease—not only physically, but also emotionally and economically.6
About the ADVANCE and MOTIVATE Studies7,8,9,10
The ADVANCE and MOTIVATE studies are Phase 3, multicenter, randomized, double-blind, placebo-controlled induction studies designed to evaluate the efficacy and safety of two doses of risankizumab, 600 mg and 1200 mg, in adults with moderate to severe Crohn’s disease, compared to placebo. Both studies included different sets of primary and secondary endpoints for outside U.S. (OUS) protocol and U.S. protocol. The primary endpoints were achievement of clinical remission (per PRO-2 for the OUS protocol, which was measured by daily stool frequency and abdominal pain score, and per CDAI for the U.S. protocol, which was measured by a CDAI score less than 150) and endoscopic response (for both protocols) at week 12. Endoscopic response is defined as a decrease in SES-CD of greater than 50 percent from baseline (or at least a greater than or equal to 50 percent decrease from baseline in patients with isolated ileal disease and a baseline SES-CD of 4), as scored by a central reviewer.
The ADVANCE study included a mixed population of patients who had responded inadequately or were intolerant to conventional and/or biologic therapy. The MOTIVATE study evaluated patients who had responded inadequately or were intolerant to biologic therapy. Topline results of the studies were shared in January 2021. More information can be found on www.clinicaltrials.gov (ADVANCE: NCT03105128; MOTIVATE: NCT03104413).
About the FORTIFY Study11,12
The FORTIFY study is a Phase 3, multicenter, randomized, double-blind, control group, 52-week maintenance study designed to evaluate the efficacy and safety of risankizumab 180 mg and 360 mg as maintenance therapy versus withdrawal in patients who responded to risankizumab induction treatment in the ADVANCE and MOTIVATE studies. This study included different sets of primary and secondary endpoints for the OUS analysis plan and U.S. analysis plan due to regulatory requirements in the different regions. The co-primary endpoints were achievement of endoscopic response and clinical remission at week 52. Endoscopic response is defined as a decrease in SES-CD of greater than 50 percent from baseline (or at least a greater than or equal to 50 percent decrease from baseline in patients with isolated ileal disease and a baseline SES-CD of 4), as scored by a central reviewer. Clinical remission is defined by SF/AP, which was measured by daily stool frequency and abdominal pain score, in the OUS analysis plan and defined by CDAI, which was measured by a CDAI score less than 150, in the U.S. analysis plan.
Topline results were announced in June 2021. An open label extension of FORTIFY will continue to assess the long-term safety of risankizumab in subjects who completed participation in FORTIFY. More information can be found on www.clinicaltrials.gov (NCT03105102).
About SKYRIZI® (Risankizumab)
SKYRIZI is an interleukin-23 (IL-23) inhibitor that selectively blocks IL-23 by binding to its p19 subunit.13,14 IL-23, a cytokine involved in inflammatory processes, is thought to be linked to a number of chronic immune-mediated diseases, including Crohn’s disease.7 The approved dose for SKYRIZI for moderate to severe plaque psoriasis and active psoriatic arthritis in the European Union is 150 mg (either as two 75 mg pre-filled syringe injections or one 150 mg prefilled pen or pre-filled injection) administered by subcutaneous injections at week 0 and 4 and every 12 weeks thereafter. The use of risankizumab in Crohn’s disease is not approved and its safety and efficacy have not been established by regulatory authorities. Phase 3 trials of SKYRIZI in psoriasis, psoriatic arthritis, Crohn’s disease and ulcerative colitis are ongoing.
