  • SEQUENCE, a Phase 3 head-to-head study, compared risankizumab to ustekinumab for the treatment of adult patients with moderately to severely active Crohn’s disease who have failed one or more anti-TNFs1
  • Risankizumab met both primary endpoints of non-inferiority for clinical remissiona (Crohn’s Disease Activity Index [CDAI]) at week 24 and superiority of endoscopic remissionb at week 48 versus ustekinumab1
  • Risankizumab showed superiority versus ustekinumab for all ranked secondary endpoints, including achievement of clinical remissiona at week 48, achievement of endoscopic responsec at week 48 and 24, achievement of steroid-free endoscopic remissiond at week 48 and achievement of steroid-free clinical remissione at week 481
  • Safety results were consistent with the overall safety profile of risankizumab, with no new safety risks identified

NORTH CHICAGO, IL, USA I October 15, 2023 I AbbVie (NYSE: ABBV) today presented positive results from the head-to-head Phase 3 SEQUENCE study that evaluated the efficacy and safety of risankizumab (SKYRIZI®, 600 mg intravenous [IV] at week 0, 4 and 8 and 360 mg subcutaneous [SC] starting at week 12 and every 8 weeks thereafter) compared to ustekinumab (STELARA®, IV dose at week 0 and 90 mg SC every 8 weeks thereafter) in patients with moderately to severely active Crohn’s disease who have failed one or more anti-TNFs.1 The data were presented at the United European Gastroenterology (UEG) Week 2023, October 14-17.

“At AbbVie, we are committed to developing medicines and generating evidence that advance care for people living with immune-mediated conditions, including inflammatory bowel diseases,” said Roopal Thakkar, M.D., senior vice president, development and regulatory affairs and chief medical officer, AbbVie. “Results such as these not only help differentiate SKYRIZI as an option for managing Crohn’s disease, but also may help to evolve the field by further informing on therapeutic strategies for patients.”

The SEQUENCE study included two sequentially tested primary endpoints:

  • The results of the first primary endpoint, clinical remission (CDAI <150) at week 24, met non-inferiority of risankizumab versus ustekinumab (pre-defined non-inferiority margin of 10%); remission rates were 59% in risankizumab group and 40% in ustekinumab group.1 This endpoint was also analyzed post hoc to test for superiority and achieved nominal p<0.01.1
  • The results of the second primary endpoint, endoscopic remission (Simple Endoscopic Score for Crohn’s disease [SES-CD] ≤4 and at least a 2-point reduction versus baseline and no sub-score greater than 1 in any individual component) at week 48 demonstrated superiority with risankizumab compared to ustekinumab with remission rates of 32% in risankizumab group and 16% in ustekinumab group (p<0.0001).1

Additionally, risankizumab demonstrated superiority compared to ustekinumab for all ranked secondary endpoints, including achievement of clinical remission at week 48, achievement of endoscopic response at week 48 and 24, achievement of steroid-free endoscopic remission at week 48, and achievement of steroid-free clinical remission at week 48.1

*The first primary endpoint was clinical remission (per CDAI) at week 24, and the second primary endpoint was endoscopic remission (per SES-CD) at week 48. Non-inferiority was met for the first primary endpoint. The second primary and all secondary endpoints achieved statistical significance with a p-value of <0.0001 vs ustekinumab.
†The first primary endpoint was tested when 50% of participants completed the week 24 visit or ended the study participation.
aClinical remission (per CDAI) was defined as CDAI <150.
bEndoscopic remission (per SES-CD) was defined as SES-CD ≤4 with at least a 2-point reduction from baseline and no sub-score greater than 1 in any individual component, as scored by central reviewer.
cEndoscopic response (per SES-CD) was defined as a decrease in SES-CD >50% from baseline (or for subjects with isolated ileal disease and a baseline SES-CD of 4, at least a 2-point reduction from baseline), as scored by central reviewer.
dSteroid-free endoscopic remission (per SES-CD) was defined as the achievement of endoscopic remission without receiving steroids at the corresponding visit.
eSteroid-free clinical remission (per CDAI) was defined as the achievement of clinical remission without receiving steroids at the corresponding visit.

“The results from the SEQUENCE study provide physicians with important data to help inform therapy options that can help patients reach treatment goals,” said Laurent Peyrin-Biroulet, M.D., Ph.D., director of the Infinity Institute, professor of gastroenterology and head of the inflammatory bowel disease group, gastroenterology department at the University Hospital of Nancy, France. “These findings reaffirm SKYRIZI as an efficacious interleukin-23 inhibitor that can support the achievement of stringent targets that contribute to improved care for patients.”

The safety profile of risankizumab in the SEQUENCE study was consistent with the known safety profile of risankizumab, with no new safety risks observed.1 The most common adverse events in risankizumab-treated patients were COVID-19, headache and Crohn’s disease. COVID-19, Crohn’s disease and arthralgia were most common among ustekinumab-treated patients.1 Serious adverse events occurred in 10% of risankizumab-treated patients and 17% of ustekinumab-treated patients, respectively.1

Risankizumab is an IL-23 inhibitor approved for Crohn’s disease, psoriatic arthritis and psoriasis and is being evaluated as a treatment for adults with moderate to severe ulcerative colitis.1

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

About Crohn’s Disease

Crohn’s disease is a chronic, systemic disease that manifests as inflammation within the gastrointestinal tract, causing persistent diarrhea and abdominal pain.2,3 It is a progressive disease, meaning it gets worse over time in a substantial proportion of patients or may develop complications that require urgent medical care, including surgery.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.2

About the SEQUENCE Study1

The SEQUENCE study is a Phase 3, multicenter, randomized, head-to-head (study drug open-label and efficacy assessment blinded) to evaluate risankizumab versus ustekinumab for the treatment of adults with moderate to severe Crohn’s disease with a history of one or more failed anti-tumor necrosis factor (TNF) therapies (intolerance or inadequate response). All participants had confirmed diagnosis for at least 3 months of moderate to severe Crohn’s disease assessed by CDAI score of 220 to 450 at baseline, stool frequency, abdominal pain score and SES-CD.

In Part 1 that lasted 48 weeks, participants were randomized to receive IV doses of 600 mg risankizumab at weeks 0, 4 and 8 and 360 mg SC maintenance doses at week 12 and every 8 weeks thereafter or weight-based IV doses of ustekinumab as a single dose and 90 mg SC doses every 8 weeks. In Part 2, participants who received risankizumab in Part 1 and completed the 48-week visit continued to receive SC risankizumab for up to an additional 220 weeks for adverse event reporting. The primary endpoints were the percentage of participants achieving clinical remission (CDAI <150) at week 24 and endoscopic remission (SES-CD ≤4, at least a 2-point reduction versus baseline, and no sub score greater than 1 in any individual variable) at week 48. Secondary endpoints include percentage of participants achieving at week 48: clinical remission (CDAI <150), steroid-free endoscopic remission, steroid-free clinical remission, and at both 24 and 48 weeks endoscopic response (decrease in SES-CD >50% from baseline or for participants with isolated ileal disease and a baseline SES-CD of 4, at least a 2-point reduction from baseline).

About Risankizumab (SKYRIZI®)

SKYRIZI is an interleukin-23 (IL-23) inhibitor that selectively blocks IL-23 by binding to its p19 subunit.4 IL-23, a cytokine involved in inflammatory processes, is thought to be linked to a number of chronic immune-mediated diseases.5 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. The use of risankizumab in ulcerative colitis is not approved and its safety and efficacy have not been established by regulatory authorities. Phase 3 trials of risankizumab in psoriasis, psoriatic arthritis, Crohn’s disease and ulcerative colitis are ongoing.5-7
