PARIS, France – January 9, 2025 – 5:35 PM CET – Abivax SA (Euronext Paris: FR0012333284 – ABVX / Nasdaq: ABVX) (“Abivax” or the “Company”), a clinical-stage biotechnology company developing innovative therapies to address chronic inflammatory diseases, today announced a significant milestone in the Phase 3 ABTECT clinical trial evaluating obefazimod for the treatment of moderately to severely active UC.
Marc de Garidel, Chief Executive Officer of Abivax, commented:
“We are thrilled to announce that the ABTECT Phase 3 trial has reached a significant milestone, with over 1,000 participants enrolled, representing 82% of our targeted enrollment. This progress underscores the enthusiasm of investigators and patients for this important trial, which remains among the fastest-enrolling Phase 3 UC trials to date.”
Mr. de Garidel went on to say, “In order to ensure a balanced representation of bio-naïve and bio-experienced participants amid heightened competition in UC trial recruitment, we now anticipate completing enrollment in Q2 2025 and delivering top-line results for the 8-week induction trial in Q3 2025. With the ABTECT trial, we aim to validate the value of obefazimod as a potentially first-in-class safe and effective oral treatment option, which remains a significant unmet need for patients with UC.”
Looking Ahead to 2025:
With Phase 3 enrollment nearing completion and key data readouts on the horizon, the Company believes 2025 is shaping up to be a pivotal year. Beyond the ABTECT trial, the Company is advancing its broader portfolio to address chronic inflammatory conditions that affect millions worldwide.
Didier Blondel, Chief Financial Officer of Abivax, added:
“Without the need for additional financing, our cash runway extends beyond the expected top-line results from the ABTECT induction trial and into Q4 2025, ensuring we remain well-positioned to execute our strategy.”
