Study Endpoints

Primary Endpoints

Percentage of participants achieving Hidradenitis Suppurativa Clinical Response 75 (HiSCR75)
Up to Week 16

Hidradenitis Suppurativa Clinical Response 75 (HiSCR75) is defined as ≥75% reduction from Baseline in the total abscess and inflammatory nodule \[AN\] count, with no increase from Baseline in abscess or draining tunnel count.

Proportion of participants who achieve clinical remission at the end of Week 16 by modified Mayo Score (mMS)
At Week 16

Clinical remission is defined as a mMS of 0 to 2, including Stool Frequency (SF) subscore of 0 or 1, Rectal Bleeding (RB) subscore of 0 and modified Mayo Endoscopic (mMES) of 0 or 1 confirmed by central reader (score of 1 does not include friability)

Percentage of participants who achieve endoscopic response at Week 16
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.

Change from baseline to Week 26 in mean 2-hour mixed meal tolerance test (MMTT) stimulated C-peptide concentration
From Baseline to Week 26

Mixed meal tolerance test MMTT stimulated C-peptide concentration is to be calculated from area under the concentration-time curve (AUC)

Period A (DB Period): Percentage of Biologic and Small Molecule Immunosuppressive-Naïve Participants Who Achieved Hidradenitis Suppurativa Clinical Response (HiSCR50) at Week 16
Week 16

The HiSCR50 was used for assessing HS treatment effectiveness in controlling inflammatory manifestations in the population. HiSCR50 was defined as \>=50% reduction from baseline in the total abscess and inflammatory nodule (AN) count, with no increase from baseline in abscess or draining tunnel count. Baseline was defined as the last available value before the first dose of DB study drug. Percentages are rounded off to the tenth decimal place.

Frequently asked questions about SAR442970

What is SAR442970 used for?

SAR442970 is an investigational small molecule being developed by Sanofi for hidradenitis suppurativa and ulcerative colitis. It is in Phase 2 clinical development for both indications, with one completed Phase 2 study in hidradenitis suppurativa and one active Phase 2 study in ulcerative colitis.

Who makes SAR442970?

SAR442970 is developed by Sanofi, which trades on the New York Stock Exchange under the ticker SNY. Sanofi is running the clinical program for SAR442970 across dermatology and gastroenterology indications, including hidradenitis suppurativa and ulcerative colitis.

What phase is SAR442970 in?

SAR442970 is in Phase 2 clinical development. A Phase 2 trial in hidradenitis suppurativa has been completed, and a Phase 2 trial in ulcerative colitis is active but no longer recruiting. SAR442970 is investigational and has not been approved by the FDA for any indication.

What clinical trials is SAR442970 in?

SAR442970 has been studied in two Phase 2 trials. NCT05849922 tested SAR442970 in adults with hidradenitis suppurativa and is completed, enrolling 86 participants. NCT06975722 is evaluating brivekimig in adults with ulcerative colitis, is active and not recruiting, and enrolled 105 participants across the United States, Europe, Australia, China, and Japan.

Is SAR442970 the same as brivekimig?

Yes, brivekimig is another name for SAR442970. The Phase 2 ulcerative colitis trial NCT06975722 refers to the drug as brivekimig, while the completed Phase 2 hidradenitis suppurativa trial NCT05849922 refers to it as SAR442970. Both names describe the same Sanofi investigational small molecule.

How is the SAR442970 ulcerative colitis trial designed?

NCT06975722 is a Phase 2, randomized, double-blind, placebo-controlled study of SAR442970 in adults 18 years and older with ulcerative colitis. It enrolled 105 participants and is active but not recruiting. The study is running in the United States, Australia, China, Czechia, France, Germany, Hungary, Japan, Moldova, Poland, Spain, and the United Kingdom.
