Sikkerhet, farmakokinetikk og effekt av PP405 hos voksne med AGA

29. september 2026 oppdatert av: Pelage Pharmaceuticals, Inc.

En randomisert, multisenter, dobbeltblind, kjøretøykontrollert, fase 2a-studie for å vurdere sikkerheten, farmakokinetikken og effekten av PP405 hos voksne med androgenetisk alopecia

The study is a two part study, designed to validate safety results from the Phase 1 PP405-001 trial while also characterizing longer term safety and PK. Part 1 of the trial is the randomized controlled portion that will focus on safety and PK following 28 days of blinded treatment administration with either PP405 or vehicle control. Part 2 of the trial is an open-label extension that will validate the results of Part 1 with 3 months of treatment administration.
