Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Etrolizumab
Treatment: Drugs - Placebo

Experimental: Induction Phase - Cohort 1 (Exploratory): Etrolizumab 210 mg - Cohort 1 enrolled participants first before Cohorts 2 and 3 in order to conduct an exploratory analysis on induction data. Participants randomized to this arm will receive one subcutaneous (SC) injection of etrolizumab (210 mg) at Weeks 0, 2, 4, 8, and 12 during the 14-week Induction Phase. In order to preserve the masking, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Experimental: Induction Phase - Cohort 1 (Exploratory): Etrolizumab 105 mg - Cohort 1 enrolled participants first before Cohorts 2 and 3 in order to conduct an exploratory analysis on induction data. Participants randomized to this arm will receive one SC injection of etrolizumab (105 mg) at Weeks 0, 4, 8, 12 and one SC injection of etrolizumab-matching placebo at Week 2 during the 14-week Induction Phase. In order to preserve the masking, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Placebo comparator: Induction Phase - Cohort 1 (Exploratory): Placebo - Cohort 1 enrolled participants first before Cohorts 2 and 3 in order to conduct an exploratory analysis on induction data. Participants randomized to this arm will receive two SC injections of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12 (and one SC injection of etrolizumab-matching placebo at Week 2) during the 14-week Induction Phase, in order to preserve the masking.

Experimental: Induction Phase - Cohort 2 (Open-Label): Etrolizumab 210 mg - Cohort 2 is enrolling participants after Cohort 1 and is considered a "feeder" cohort to help achieve the necessary sample size for the Maintenance Phase. Participants randomized to this arm will receive one SC injection of open-label etrolizumab (210 mg) at Weeks 0, 2, 4, 8, and 12 during the 14-week Induction Phase. In order to preserve the masking for the dose of etrolizumab, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Participants randomized to this arm will receive one SC injection of open-label etrolizumab (105 mg) at Weeks 0, 4, 8, 12 and one SC injection of etrolizumab-matching placebo at Week 2 during the 14-week Induction Phase. In order to preserve the masking of the dose of etrolizumab, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Experimental: Induction Phase - Cohort 3 (Pivotal): Etrolizumab 210 mg - Cohort 3 is the last to enroll participants (after Cohort 2) and will be the pivotal cohort for the Induction Phase. Participants randomized to this arm will receive one SC injection of etrolizumab (210 mg) at Weeks 0, 2, 4, 8, and 12 during the 14-week Induction Phase. In order to preserve the masking, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Participants randomized to this arm will receive one SC injection of etrolizumab (105 mg) at Weeks 0, 4, 8, 12 and one SC injection of etrolizumab-matching placebo at Week 2 during the 14-week Induction Phase. In order to preserve the masking, participants will also receive one SC injection of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12.

Placebo comparator: Induction Phase - Cohort 3 (Pivotal): Placebo - Cohort 3 is the last to enroll participants (after Cohort 2) and will be the pivotal cohort for the Induction Phase. Participants randomized to this arm will receive two SC injections of etrolizumab-matching placebo at Weeks 0, 4, 8, and 12 (and one SC injection of etrolizumab-matching placebo at Week 2) during the 14-week Induction Phase, in order to preserve the masking.

Placebo comparator: Maintenance Phase - Placebo Responders: Placebo - Participants who received placebo during the Induction Phase (from Cohorts 1 and 3) and achieved a CDAI-70 response at Week 14 will undergo a sham randomization into the Maintenance Phase. Placebo responders from induction will receive blinded maintenance treatment with an SC injection of placebo once every 4 weeks (q4w) from Week 16 to Week 64.

Placebo comparator: Maintenance Phase - Etrolizumab Responders: Placebo - Participants who received etrolizumab during the Induction Phase (from Cohorts 1-3) and achieved a CDAI-70 response at Week 14 without the use of rescue therapy will be re-randomized into the Maintenance Phase. Etrolizumab responders from induction who are re-randomized to this arm will receive blinded maintenance treatment with an SC injection of placebo q4w from Week 16 to Week 64.

Experimental: Maintenance Phase - Etrolizumab Responders: Etrolizumab 105 mg - Participants who received etrolizumab during the Induction Phase (from Cohorts 1-3) and achieved a CDAI-70 response at Week 14 without the use of rescue therapy will be re-randomized into the Maintenance Phase. Etrolizumab responders from induction who are re-randomized to this arm will receive blinded maintenance treatment with an SC injection of etrolizumab (105 mg) q4w from Week 16 to Week 64.

Summary
Brief summary
This is a multicenter, Phase 3, double-blind, placebo-controlled study evaluating the efficacy, safety, and tolerability of etrolizumab compared with placebo during induction and maintenance treatment of moderately to severely active Crohn's Disease (CD). The target population includes participants with CD who are refractory or intolerant to corticosteroids (CS) and/or immunosuppressant (IS) therapy and who have either not received prior anti-tumor necrosis factor (anti-TNF) therapy (TNF-naive) or who have had prior exposure to anti-TNF therapies and demonstrated inadequate responses or intolerance to anti-TNFs.

The study period will consist of a Screening Phase (up to 35 days) plus (+) a 14-week Induction Phase + a 52-week Maintenance Phase + a 12-week Safety Follow-up Phase. At Week 14 (end of Induction Phase), participants achieving a decrease from baseline of at least 70 points in the Crohn's Disease Activity Index (CDAI) score (CDAI-70 response) without the use of rescue therapy will continue to the Maintenance Phase.
