• A significantly higher proportion of patients with moderately to severely active ulcerative colitis treated with risankizumab achieved the primary endpoint of clinical remission^a (per Adapted Mayo Score) compared to placebo at week 12 in the Phase 3 INSPIRE induction study
• All secondary endpoints, including clinical, endoscopic and histologic outcomes, were met
• Safety results in this study were consistent with the known safety profile of risankizumab, with no new safety risks observed¹
• Building on AbbVie's growing gastroenterology portfolio, risankizumab is an IL-23 inhibitor being evaluated as a treatment for adults with moderate to severe ulcerative colitis and approved for Crohn's disease, psoriatic arthritis, and psoriasis¹

NORTH CHICAGO, Ill., March 23, 2023 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced positive top-line results from INSPIRE, a Phase 3 induction study, showing risankizumab (SKYRIZI^®,1200 mg intravenous [IV], at weeks 0, 4 and 8) met the primary endpoint of clinical remission (per Adapted Mayo Score) at week 12, as well as all secondary endpoints in adult patients with moderately to severely active ulcerative colitis.¹ In the study, 20.3% of patients receiving risankizumab achieved clinical remission compared to 6.2% of patients receiving placebo (p<0.00001).¹ The INSPIRE study enrolled patients that demonstrated intolerance or inadequate response to conventional therapies and/or advanced therapies (biologics, JAK inhibitors and S1P receptor modulators).¹ 

"Our commitment to people living with gastroenterological conditions continues to grow," said Roopal Thakkar, M.D., senior vice president, development, regulatory affairs and chief medical officer, AbbVie. "These encouraging results help support the potential risankizumab has to improve clinical, endoscopic and histologic outcomes in patients with ulcerative colitis."

A significantly greater proportion of patients treated with risankizumab achieved endoscopic improvement at week 12 compared to placebo (36.5% vs 12.1%; p<0.00001).¹ Furthermore, 24.5% of patients treated with risankizumab achieved histologic-endoscopic mucosal improvement at week 12 vs 7.7% of those receiving placebo (p<0.00001).¹ 

"It is impressive to see the meaningful responses that were achieved in the INSPIRE study, which demonstrates the potential of risankizumab to serve as an option across inflammatory bowel diseases," said Edouard Louis, M.D., Ph.D., professor and head of the department of gastroenterology, University Hospital CHU of Liège Belgium, INSPIRE study investigator. "These results suggest that risankizumab may help patients coping with the challenging symptoms of ulcerative colitis, which include abdominal pain, bowel urgency and fecal incontinence."

During the 12-week, double-blind, placebo-controlled period, the safety profile of risankizumab 1200 mg IV was consistent with the safety profile observed in previous studies across other indications, with no new safety risks observed.¹ The most common adverse events observed in the risankizumab group were COVID-19, anemia and arthralgia. Serious adverse events occurred in 2.3% of patients in the risankizumab 1200 mg IV group compared to 10.2% of patients in the placebo group.¹ Rates of serious infections were 0.6% in those treated with risankizumab 1200 mg IV and 1.2% in patients who received placebo.¹ There was one death in the risankizumab 1200 mg group due to COVID-19 pneumonia on study day 33. There were no adjudicated major adverse cardiac events (MACE), no adjudicated anaphylactic reaction events and no malignancy events reported in the risankizumab group.¹

Use of risankizumab in ulcerative colitis is not approved and its safety and efficacy have not been evaluated by regulatory authorities. The maintenance study for ulcerative colitis is ongoing.

Risankizumab (SKYRIZI) is part of a collaboration between Boehringer Ingelheim and AbbVie, with AbbVie leading development and commercialization globally.

About Ulcerative Colitis

Ulcerative colitis is a chronic, idiopathic, immune-mediated inflammatory bowel disease (IBD) of the large intestine that causes continuous mucosal inflammation extending, to a variable extent, from the rectum to the more proximal colon.^2,3 The hallmark signs and symptoms of ulcerative colitis include rectal bleeding, abdominal pain, bloody diarrhea, tenesmus (a sense of pressure), urgency and fecal incontinence.^3,4 The disease course of ulcerative colitis varies between patients and can range from quiescent disease to chronic refractory disease, which in some cases can lead to surgery or complications, including cancer or death.^4,5 The severity of symptoms and unpredictability of disease course can lead to substantial burden and often disability among those living with the disease.⁶

About INSPIRE¹

INSPIRE is a multicenter, randomized, double-blind, placebo-controlled Phase 3 study evaluating the efficacy and safety of risankizumab 1200 mg IV administered every four weeks as induction therapy in subjects with moderately to severely active ulcerative colitis.

The primary endpoint is clinical remission (per adapted Mayo Score, defined as SFS ≤1 and not greater than baseline, RBS of 0 and endoscopic subscore ≤1 without friability) at week 12. Secondary endpoints include clinical response (decrease from baseline in the Adapted Mayo score ≥2 points and ≥30% from baseline, plus a decrease in RBS ≥1 or an absolute RBS ≤1), endoscopic improvement (endoscopic subscore ≤1 without friability), and histologic endoscopic mucosal improvement (HEMI, endoscopic subscore of 0 or 1 without friability and Geboes score ≤3.1) at week 12. More information can be found on www.clinicaltrials.gov (NCT03398148).

About Risankizumab (SKYRIZI^®)

SKYRIZI is an interleukin-23 (IL-23) inhibitor that selectively blocks IL-23 by binding to its p19 subunit.⁷ IL-23, a cytokine involved in inflammatory processes, is thought to be linked to a number of chronic immune-mediated diseases.⁸ SKYRIZI is approved by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency for the treatment of plaque psoriasis, psoriatic arthritis and Crohn's disease. Phase 3 trials of SKYRIZI in psoriasis, psoriatic arthritis, Crohn's disease and ulcerative colitis are ongoing.^8,9,10
