Principal investigator Prof. Séverine Vermeire, M.D., Ph.D., to present Abivax’s poster on
PARIS, France, September 27, 2022 – 06:00 p.m. (CEST) – Abivax SA (Euronext Paris: FR0012333284 – ABVX), a phase 3 clinical-stage biotechnology company developing novel therapies that modulate the immune system to treat chronic inflammatory diseases, viral infections, and cancer, announces today that its abstract on the obefazimod interim 48-week safety and efficacy analysis from the ongoing open-label phase 2b maintenance study in moderate to severe ulcerative colitis (UC) has been selected as “one of the best abstracts” for UEG (United European Gastroenterology) Week 2022. The corresponding poster is therefore eligible for an oral presentation during a moderated poster session, in addition to the poster exhibition in the Science Lounge and the Virtual Poster Exhibition.
UEG Week 2022 takes place in Vienna, Austria, from October 8-11, 2022, and is one of the world’s leading congresses focused on gastrointestinal diseases, such as Inflammatory Bowel Diseases (IBD).
The poster will be presented by Prof. Séverine Vermeire, M.D., Ph.D., the study’s principal investigator. Participants will have the opportunity to ask questions after the presentation.
The moderated poster sessions at this year’s UEG Week will neither be recorded nor streamed online. Only registered UEG Week participants can attend the poster session at the conference venue.
In addition to the selection of the abstract by UEG, the obefazimod phase 2b study results in UC have recently been scientifically validated with the publication of an article in the peer-reviewed journal “The Lancet Gastroenterology & Hepatology”. The title of the article is “ABX464 (obefazimod) for moderate-to-severe, active ulcerative colitis: a phase 2b, double-blind, randomised, placebo-controlled induction trial and 48 week, open-label extension”.
Obefazimod global pivotal phase 3 clinical program in UC
Following the promising results of the phase 2a and phase 2b clinical induction and maintenance studies with obefazimod in UC, Abivax launched a global pivotal phase 3 clinical program with its drug candidate in moderate to severe ulcerative colitis patients.
1,200 UC patients across 36 countries will take part in the pivotal phase 3 program that consists of two induction studies and a single subsequent maintenance study (ABTECT-1 (ABX464-105) and ABTECT-2 (ABX464-106) induction trials and ABTECT maintenance trial (ABX464-107)). These three pivotal studies are all randomized, double-blind, and placebo controlled, using independent, blinded review of the videotaped endoscopies. The primary efficacy endpoint assessed at week 8 (induction) and at week 44 (maintenance) will be clinical remission according to the modified Mayo Score, as required by FDA.
Currently, more than 430 study sites, out of the targeted 600 sites, have already been qualified to take part in the phase 3 trials.
In August, Abivax received approval from the central US Institutional Review Board (IRB) for the protocols of the phase 3 induction studies. This allows the initiation of enrollment of patients into the two studies in UC in the US. A first patient is anticipated to be included at the end of September 2022.
