Clinical trials in IBD - Moderated Poster Session 3 (MP250)
October 10, 2022 - at 11:54 a.m.-12:00 (noon) CEST (5:54-6:00 a.m. EST)
Prof. Séverine Vermeire, M.D., Ph.D., Head of the IBD Center at the University Hospitals Leuven, Belgium, and principal investigator of the obefazimod phase 2a and phase 2b clinical studies, as well as of the obefazimod global phase 3 clinical program in UC
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.
