Absci Advances AI-Designed Antibody ABS-201 into Phase 2 Trial for Endometriosis

  • Absci plans to initiate a global, multi-center Phase 2 trial for ABS-201, an AI-designed anti-prolactin receptor antibody, in mid-2027.
  • The trial will assess efficacy and safety in 150 patients with surgically-diagnosed endometriosis and moderate to severe pain.
  • ABS-201 is designed using Absci’s generative AI platform, offering a non-hormonal approach to endometriosis treatment.
  • Dose levels for the Phase 2 trial will be determined based on data from the ongoing HEADLINE trial for pattern hair loss.

Absci’s advancement of ABS-201 into Phase 2 trials underscores the growing role of AI in drug discovery, particularly for conditions with limited treatment options. The non-hormonal approach to endometriosis aligns with broader industry trends toward targeted therapies with differentiated safety profiles. Success in this trial could position ABS-201 as a potential best-in-class therapeutic in a market affecting roughly one in ten women of reproductive age.
