Trial Summary

What is the purpose of this trial?

The primary purpose of this study is to evaluate the efficacy and safety of a single intravenous (IV) re-induction dose of approximately 6 milligram per kilogram (mg/kg) ustekinumab in participants with secondary loss of response (LoR) to subcutaneous (SC) every 8 Weeks (q8w) 90 mg ustekinumab maintenance therapy.

Eligibility Criteria

Inclusion Criteria

A history of Crohn's disease or fistulizing Crohn's disease of at least 3 months' duration, with colitis, ileitis, or ileocolitis, confirmed at any time in the past by radiography, histology, and/or endoscopy

Currently receiving subcutaneous 90 mg every 8 weeks (q8w) ustekinumab maintenance therapy and initially responded to ustekinumab induction therapy, administered according to the local label, followed by secondary loss of response (LoR) to ustekinumab. Secondary LoR to ustekinumab is defined as active disease at study baseline, proven by a Crohn's Disease Activity Index (CDAI) score of greater than or equal to (>=) 220 and <=450 with at least one of the following: Elevated C-reactive protein (CRP) (>3.0 milligram per liter [mg/L]); and/or elevated Fecal calprotectin (fCal) >250 milligram per kilogram [mg/kg]); and/or endoscopy (performed less than or equal to (<=) 3 months before baseline) with evidence of active Crohn's disease, (defined as one or more ulcerations in the ileum and/or colon)

Participants receiving either oral 5-aminosalicylic acid (5-ASA) compounds, oral corticosteroids (for example {e.g.}, prednisone, budesonide) at a prednisone-equivalent dose of <=40 mg/day or <=9 mg/day of budesonide, antibiotics used as the primary treatment of Crohn's disease, or conventional immunomodulators (i.e., azathioprine [AZA], 6-mercaptopurine [6-MP], or methotrexate [MTX]) are permitted providing the doses indicated are stable before baseline or have been discontinued before baseline within the protocol defined durations

Active Control

Group I: Group 1: Ustekinumab (IV re-induction)Experimental Treatment3 Interventions

Participants who experience a secondary loss of response (LoR) to 90 mg ustekinumab maintenance treatment, administered subcutaneously every 8 weeks (q8w) will receive a weight-tiered based ustekinumab IV re-induction dose of approximately 6 mg/kg and matching placebo subcutaneously at Week 0. At Weeks 8 and 16, all participants will receive SC maintenance injections of 90 mg ustekinumab. Participants will resume their standard-of-care therapy at Week 24 at the discretion of the treating physician.

Group II: Group 2: Ustekinumab (Continuous q8w SC maintenance)Active Control2 Interventions

Participants who experience a secondary LoR to 90 mg ustekinumab maintenance treatment, administered subcutaneously q8w will receive ustekinumab 90 mg subcutaneously and matching placebo intravenously at Week 0. At Weeks 8 and 16, all participants will receive SC maintenance injections of 90 mg ustekinumab. Participants will resume their standard-of-care therapy at Week 24 at the discretion of the treating physician.
