Absci Unveils Preclinical Data for ABS-201, Promoting Hair Growth
Absci unveiled new preclinical data for ABS-201, an AI-designed antibody targeting the prolactin receptor. The data demonstrate that ABS-201 effectively stimulates hair growth by regenerating the stem cell niche as well as promoting additional key growth modulators. Mechanistically, ABS-201 treatment significantly inhibited the prolactin receptor, or PRLR, signaling pathway. This inhibition correlated with prolongation of anagen and restoration of growth signaling, preservation and expansion of stem cell niche, potential for follicle reconversion, activity in endogenous settings. Together, data from these studies further validate the anti-PRLR mechanism in androgenetic alopecia. Absci anticipates an interim data readout from its Phase 1/2a HEADLINE study in the second half of 2026.
