Positive interim Phase I data for hair-loss drug ABS-201 shows safety and long half-life, driving stock surge.

Absci Corporation shares surged 36% to close at $10.08 after the company reported positive interim Phase I data for its androgenetic alopecia candidate ABS-201. The single ascending dose portion of the HEADLINE study showed the PRLR-targeting antibody was well tolerated with no serious adverse events and an estimated half-life of at least 65 days, supporting infrequent dosing. The trial has advanced into the multiple ascending dose phase, with interim proof-of-concept data expected in the second half of 2026 and full results in early 2027. The stock has gained 40.3% over the past four weeks.
