成人AGAにおけるPP405の安全性、薬物動態および有効性

2026年9月29日 更新者：Pelage Pharmaceuticals, Inc.

男性型脱毛症の成人における PP405 の安全性、薬物動態、および有効性を評価するための無作為化、多施設共同、二重盲検、ビヒクル対照、第 2a 相試験

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.
