Study Overview

This is a phase 2b, randomized, double-blind, 3-arm study for the treatment of Crohn's disease. The primary objective of this study is to assess the efficacy of different doses of SAR442970 compared with placebo in participants with moderate to severe Crohn's disease. The total study duration is up to 168 weeks, with a treatment period of up to 158 weeks including an open-label (OL) long-term extension (LTE) period of up to 104 weeks for eligible participants.

Eligibility Criteria

You may be eligible for this study if you meet the following criteria:

  • Conditions: Crohn's Disease
  • Age: 18 years - 75 years
  • Gender: All

Inclusion Criteria:

  • Diagnosis of Crohn's Disease (CD) for at least 3 months prior to screening
  • Confirmed diagnosis of moderate-to-severe CD
  • History of prior exposure to standard treatment (5-Amino Salicylates (5-ASAs), steroids, immunomodulators or antibiotics) or advanced therapies (ATs) (biologics or small molecules), but having inadequate response to, loss or response to or intolerance to at least one of these therapies
  • On stable doses of standard treatments prior to screening (Oral 5-ASA compounds, Oral corticosteroids, Azathioprine (AZA), 6-Mercaptopurine (6-MP), or Methotrexate (MTX), or Antibiotics, etc.)
  • Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies

Exclusion Criteria:

  • Participants with active Ulcerative Colitis (UC), indeterminate colitis, adenomatous colonic polyps not excised, colonic mucosal dysplasia (low- or high-grade dysplasia) or short bowel syndrome
  • Participants with CD isolated to the stomach, duodenum, jejunum, or perianal region, without colonic or ileal involvement
  • Participants with following ongoing known complications of CD:

    • Any manifestation that might require bowel surgery while enrolled in the study
    • Participant with ostomy or ileoanal pouch
    • Participant diagnosed with conditions that could interfere with drug absorption including but not limited to short bowel syndrome
    • Participant with surgical bowel resection within the past three months prior to screening, or a history of >3 bowel resections
  • History of any other condition which, in the opinion of the Investigator, would put the participant at risk by participation in the study

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

This study investigates the treatment of Crohn's disease, focusing on evaluating the effectiveness of different doses of an investigational medication compared to a placebo in individuals with moderate to severe Crohn's disease.

Participants will be randomly assigned to one of three study arms, receiving either the investigational medication or a placebo. The study is double-blind, meaning neither the participants nor the researchers will know who is receiving the actual medication. Participants will continue their current stable doses of standard treatments during the study. A placebo is an inactive substance that looks like the investigational medication but does not contain any medicine.

  • Who can participate: Adults who have been diagnosed with moderate to severe Crohn's disease for at least 3 months and have had an inadequate response or intolerance to standard or advanced therapies may be eligible. Participants must be on stable doses of standard treatments before screening.
  • Study details: Participants will be involved in a randomized study where they will either receive the investigational medication or a placebo. They will continue their current stable treatments during the study.
  • Study timelines: The study will last up to 168 weeks.
