Condition(s) targeted: Active Ulcerative Colitis

Intervention: BG9418 (Interferon beta-1a) (Drug); Placebo (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: Biogen

Official(s) and/or principal investigator(s):
Medical Director, Study Director, Affiliation: Biogen


The primary objective of the study is to evaluate the clinical activity of interferon beta-1a in participants with moderate to severe ulcerative colitis (UC). Secondary objectives of this study are to determine (i) the safety and tolerability of interferon beta-1a in participants with moderate to severe UC, and (ii) the percentage of participants, with a decrease in the Simple Clinical Colitis Activity Index (SCCAI) score of ≥3 points at Week 8.

Clinical Details

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of Avonex in Subjects With Moderate to Severe Ulcerative Colitis

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver), Primary Purpose: Treatment

Primary outcome: Percentage of Participants With a Clinical Response

Secondary outcome:

Number of Participants With Adverse Events (AEs)

Percentage of Participants With a Decrease on Simple Clinical Colitis Activity Index (SCCAI) of ≥3 Points at Week 8


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.

and moderate to severe disease on endoscopy (Mayo endoscopic score of at least 2) despite prior or concomitant treatment

- Colonoscopy within past 5 years for extent of disease and to exclude polyps

- For subjects with UC for more than 10 years, colonoscopy with appropriate biopsies

- History of malignant disease

- History of major abdominal surgery (e. g., gastrectomy) within past 5 years

- History of small bowel or colonic obstruction or resection

- History of drug or alcohol abuse (as defined by the Investigator) within 2 years

prior to Screening
