Study Overview

This is a phase 2, 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 and having inadequate response to, loss of response to or intolerance to standard therapy with any of the following compounds: (5-Amino Salicylates (5-ASAs), 6-Mercaptopurine (6-MP), Azathioprine (AZA), Methotrexate (MTX), oral or corticosteroids 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, AZA, 6-MP, or 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.

The purpose of this research study is to learn about the effects and safety of an investigational study drug compared with a placebo in people with moderate to severe Crohn’s disease. A placebo looks like the investigational study drug but does not contain active medication.

Participants will receive either the investigational study drug (at one of different dose levels) or a placebo.

Who can participate:
People with moderate to severe Crohn’s disease may be able to participate if they:

  • Have had a diagnosis of Crohn’s disease for at least three months
  • Have moderate to severe Crohn’s disease
  • Have tried at least one standard Crohn’s disease treatment in the past that did not work well enough, stopped working, or caused difficult side effects
  • Are on stable doses of their standard Crohn’s disease treatments before starting the study

Study timeline and visits:
Participation lasts up to 168 weeks. Some eligible participants may be able to continue in a longer-term part of the study.
