PP405 trials have completed phase 2a, showing promising results with a 31% stat for hair density increase, and are moving directly to phase 3. Detailed results will be presented at a medical conference in 2026.

The conversation discusses the safety study of PP405, emphasizing that early trials focus on safety rather than efficacy, and that any efficacy data from such a short study should be viewed skeptically. It also highlights that the information released is primarily for securing funding, and that meaningful efficacy results are expected in later phases.
