A Study to Investigate Efficacy and Safety of SAR442970 in Patients With Crohn's Disease
(CHROMA CD)
What this study is about
This is a phase 2b, randomly assigned, where neither patients nor doctors know which treatment is given, 3-treatment group$1 study for the treatment of Crohn's disease. The primary objective of this study is to assess the effectiveness of different doses of SAR442970 compared with placebo in participants with moderate to severe Crohn's disease.
View original scientific description
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.
Interventions
DRUG
SAR442970
Route of Administration: Subcutaneous
DRUG
Placebo
Route of Administration: Subcutaneous
Primary outcome measures
Percentage of participants who achieve endoscopic response at Week 16
Time frame: From Baseline to Week 16
Endoscopic response is defined as decrease in Simple Endoscopic Score for Crohn's Disease (SES-CD) \>50% from baseline (or a decrease of at least 2 points for subjects with a baseline score of 4 or more and isolated ileal disease) based on central reading. The SES-CD evaluates 4 endoscopic variables (ulcer size, ulcerated surface, affected surface, and narrowing, each on a scale from 0 (none) to 3 in 5 segments assessed during ileocolonoscopy. The total score is the sum of the 4 endoscopic variable scores and ranges from 0 to 56, where higher scores indicate more severe disease.
Who can participate

- 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
