Absci Corporation has announced the dosing of the first healthy volunteers in its Phase 1/2a HEADLINE study evaluating ABS-201, an investigational anti-prolactin receptor (PRLR) antibody designed using Absci's generative AI platform. The clinical trial aims to assess the safety, tolerability, immunogenicity, pharmacokinetics, pharmacodynamics, and efficacy of ABS-201 for the treatment of androgenetic alopecia. Interim data from this study are anticipated in the second half of 2026. Additionally, Absci plans to pursue endometriosis as a further indication for ABS-201, with Phase 2 clinical development in endometriosis expected to begin in the fourth quarter of 2026. An interim readout from the Phase 2 trial in endometriosis is projected for the second half of 2027. Additional new human ex vivo data supporting the PRLR mechanism of action will be disclosed at a virtual KOL seminar scheduled for December 11.
