Phase 2RecruitingNCT06958536

Sanofi99 enrolled

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.

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.

Outcomes

Primary Outcomes

Percentage of participants who achieve endoscopic response at 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.

Time frame: From Baseline to Week 16

Secondary Outcomes

Percentage of participants who achieve clinical remission based on Crohn's Disease Activity Index (CDAI) at Week 16

CDAI clinical remission is defined as CDAI score \<150. CDAI is a composite instrument that includes participant symptoms evaluated over 7 days (abdominal pain, stool frequency and general well-being), as well as presence of complications (arthritis/arthralgia, iritis/uveitis, erythema nodosum/pyoderma gangrenosum/aphthous stomatitis, anal fissure/fistula/abscess, other fistula, and fever), the use of antidiarrheal medicines, presence of an abdominal mass, hematocrit, and body weight. These items are scored individually, weighted, and do not contribute equally to the overall score. The CDAI is derived from summing up the weighted individual scores of eight items. CDAI approximately ranges from 0 to 600 with higher scores indicating more severe disease.

Time frame: At Week 16

Percentage of participants who achieve PRO-2 (Patient Reported Outcome) clinical remission at Week 16

PRO-2 clinical remission is defined as using the average daily Stool Frequency (SF) ≤3 and not worse than baseline and average daily AP ≤1 and not worse than baseline.

Time frame: At Week 16

Percentage of participants who achieve endoscopic remission based on centrally read SES-CD at Week 16

Endoscopic remission is defined as SES-CD ≤4 and at least 2 point reduction versus baseline and no subscore \>1 in any individual variable based on central reading.

Time frame: At Week 16

Percentage of participants who achieve both clinical remission based on CDAI score and endoscopic response based on SES- CD at Week 16

CDAI clinical remission is defined as CDAI score \<150, endoscopic response is defined as a decrease in 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.

Time frame: At Week 16

Percentage of participants who achieve CDAI clinical response at Week 16

CDAI clinical response is defined as reduction of CDAI ≥100 points from baseline.

Time frame: At Week 16

Change from baseline in the Inflammatory Bowel Disease Questionnaire (IBDQ) score

The Inflammatory Bowel Disease Questionnaire (IBDQ) is a 32-item instrument assessing health-related quality of life in IBD patients across four dimensions: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items), and social function (5 items). Each question evaluates experiences over the previous two weeks on a 7-point Likert scale from 1 (worst) to 7 (best). The total score ranges from 32 to 224, with higher scores indicating better quality of life. Both domain-specific and overall scores can be calculated.

Time frame: From Baseline to Week 16

Change from baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) score

The FACIT-F questionnaire assesses fatigue associated with anemia through 13 fatigue-related questions. Each item is scored on a 5-point Likert scale (0="not at all" to 4="very much"), with total scores ranging from 0 to 52. High scores represent less fatigue. For Crohn's Disease patients, a 7-10 point improvement on the FACIT-F total score may represent meaningful improvements.
