Abivax Stock Surge on Promising Clinical Trial Results
Abivax SA (NASDAQ: ABVX) stock has soared following the announcement of highly encouraging topline results from its Phase 3 ABTECT-1 and ABTECT-2 trials, which focus on the use of the experimental oral treatment, obefazimod (ABX464), in adults suffering from active ulcerative colitis.
Key Breakthroughs in Ulcerative Colitis Treatment
The trials represent significant progress in the treatment of this chronic inflammatory bowel disease, showcasing favorable efficacy and renewing hope for many patients impacted by such conditions. These findings reflect Abivax's commitment to developing innovative solutions in biotechnology.
Details of the ABTECT Trials
The dual trials evaluated the once-daily administration of obefazimod at dosages of 25 mg and 50 mg among 1,275 participants diagnosed with moderately to severely active ulcerative colitis. By achieving this critical step, the company is making strides to provide effective alternatives for patients in need.
Trial Statistics and Results
The results revealed that the 50 mg treatment met its primary FDA endpoint of clinical remission at Week 8 for both trials. ABTECT-1 exhibited a remarkable placebo-adjusted clinical remission rate of 19.3% while ABTECT-2 followed closely with 13.4%. This showcases the potential effectiveness of the treatment.
