– In U-EXCEED, a significantly higher proportion of patients with moderate to severe Crohn’s disease treated with upadacitinib (45 mg once daily for induction) achieved both primary endpoints of clinical remission[a,b] and endoscopic response[c] compared to placebo at week 12[1]
– The study showed that a significantly higher proportion of upadacitinib-treated patients achieved steroid-free clinical remission[d] at week 12 compared to placebo[1]
– The safety results in this study were consistent with the known profile of upadacitinib, with no new safety risks observed[1-6]
– Upadacitinib, a selective and reversible JAK inhibitor discovered and developed by AbbVie, is being studied as an oral therapy for moderate to severe Crohn’s disease and several other immune-mediated inflammatory diseases[1,6-14]
NORTH CHICAGO, IL, USA I December 6, 2021 I AbbVie (NYSE: ABBV) today announced positive top-line results from U-EXCEED, a Phase 3 induction study, showing upadacitinib (45 mg once daily) achieved both primary endpoints of clinical remissiona,b and endoscopic responsec at week 12.1 The U-EXCEED study enrolled patients with moderate to severe Crohn’s disease who had an inadequate response or were intolerant to biologic therapy, with over 60 percent having previously failed two or more biologics.1 U-EXCEED is the first of two Phase 3 induction studies to evaluate the safety and efficacy of upadacitinib in adults with moderate to severe Crohn’s disease.1
“The data from this first Phase 3 induction study in Crohn’s disease suggest upadacitinib may help address the needs of patients suffering from this disease, as demonstrated in stringent endpoints such as endoscopic response,” said Michael Severino, M.D., vice chairman and president, AbbVie. “We continue to leverage our expertise in IBD by driving research and development that help shape the IBD landscape and elevate standards of care for patients.”
In U-EXCEED, clinical remission was measured by the Crohn’s Disease Activity Index (CDAI) and by the patient-reported symptoms of stool frequency/abdominal pain (SF/AP).1 A significantly greater proportion of patients treated with a 12-week induction regimen of upadacitinib 45 mg daily achieved clinical remission per CDAI at week 12 compared to placebo (39 percent, versus 21 percent; p<0.0001).1 Similar results were seen with clinical remission per SF/AP (40 percent in upadacitinib-treated patients versus 14 percent in placebo-treated patients; p<0.0001).1 In this study, all patients were also evaluated for improvement in the intestinal mucosa by endoscopy.1 At week 12, a significantly greater proportion of patients treated with upadacitinib 45 mg achieved endoscopic response compared to the placebo group (35 percent versus 4 percent; p<0.0001).1
Among patients taking corticosteroids at baseline, a significantly higher proportion of patients receiving upadacitinib 45 mg achieved steroid-free clinical remissiond per CDAI and per SF/AP compared to placebo at week 12.1 A significantly higher proportion of patients receiving upadacitinib compared to placebo also achieved early symptom improvement measured by CR-100 (defined as reduction of CDAI ≥100 points from baseline) at week 2 as well as clinical remission at week 4.1
“I am thrilled to see the results of this first Phase 3 induction study of upadacitinib, particularly in this difficult-to-treat refractory patient population,” said Jean-Frederic Colombel, M.D., professor of medicine and director of Inflammatory Bowel Disease Center, Icahn School of Medicine, Mount Sinai, and U-EXCEED study investigator. “These results demonstrate upadacitinib’s potential to achieve endoscopic response and clinical remission, including steroid-free clinical remission, at 12 weeks in patients living with Crohn’s disease.”

a Clinical remission (per CDAI) is defined as CDAI <150. | ||
b Clinical remission per SF (stool frequency)/AP (abdominal pain) (also referred to as PRO-2) is defined as average daily very soft or liquid stool frequency ≤2.8 AND average daily abdominal pain score ≤1.0, and both not greater than baseline. | ||
c Endoscopic response is defined as a decrease in simple endoscopic score for Crohn’s disease (SES-CD) of >50 percent from baseline (or at least a 2-point reduction from baseline for subjects with a baseline SES-CD of 4), as scored by central reviewer. |
During the 12-week, double-blind, placebo-controlled period, the safety profile of upadacitinib 45 mg was consistent with the safety profile observed in previous studies across indications, with no new safety risks observed.1 The most common adverse event was nasopharyngitis for upadacitinib and exacerbation of Crohn’s disease for placebo.1 Serious adverse events occurred in 9.3 percent of patients in the upadacitinib 45 mg group compared to 9.9 percent of patients in the placebo group.1 Rates of serious infections were 2.8 percent in those treated with upadacitinib 45 mg and 1.8 percent in patients who received placebo.1 All events of herpes zoster (1.5 percent of patients) were nonserious and reported in the upadacitinib group only.1 There was one case of adjudicated gastrointestinal perforation in the upadacitinib group.1
An additional 207 patients at week 12 received an upadacitinib 45 mg daily induction regimen (including non-responders to placebo or from an open label arm).1 Among these patients, there were two additional cases of adjudicated gastrointestinal perforation reported.1 Overall, the safety results in these patients were consistent with what was observed in the upadacitinib 45 mg group during the placebo-controlled period.1
In the study, no treatment-emergent cases of adjudicated cardiovascular event, malignancy, thromboembolic event or death were reported across treatment groups.1
Full results from the U-EXCEED study will be presented at upcoming medical conferences and published in a peer-reviewed medical journal. Use of upadacitinib in Crohn’s disease is not approved and its safety and efficacy have not been evaluated by regulatory authorities.
dSteroid-free clinical remission is defined as clinical remission (per CDAI <150, or per SF/AP with average daily SF ≤2.8 and not worse than baseline and average daily AP score ≤1 and not worse than baseline) and discontinuation of corticosteroid use among patients taking corticosteroids at baseline. |
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.15-17 It is a progressive disease, meaning it gets worse over time in a substantial proportion of patients.16,17 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.18
About U-EXCEED1,14
The U-EXCEED study is one of two Phase 3, multicenter, randomized, double-blind, placebo-controlled induction studies designed to evaluate the efficacy and safety of upadacitinib 45 mg induction treatment in adults with moderate to severe Crohn’s disease. U-EXCEED enrolled patients who had inadequately responded to or are intolerant of biologic therapy. The second induction study evaluated patients who have had an inadequate response or intolerance to one or more conventional and/or biologic therapies.19
The U-EXCEED study includes three study parts. Part 1 is the 12-week placebo-controlled induction portion. Part 2 is the open label arm of U-EXCEED evaluating an additional group of patients who received upadacitinib 45 mg for 12 weeks. In Part 3, patients who did not achieve clinical response in Part 1 or Part 2 received an extended treatment of upadacitinib 45 mg or 30 mg for 12 weeks.
The study included slightly different sets of primary and secondary endpoints for the U.S. Food and Drug Administration (FDA) and the EU European Medicines Agency (EMA). The primary endpoints were achievement of clinical remission (per CDAI for the U.S. FDA, and per SF/AP for the EU EMA, which was measured by average daily stool frequency and abdominal pain score) and endoscopic response (per SES-CD) at week 12. More information can be found on www.clinicaltrials.gov (NCT03345836).
