The Role of Candidate Pharmacogenetic Variants in Determining Valproic Acid Efficacy, Toxicity, and Concentrations in Patients with Epilepsy

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

Oral PTD-DBM was discussed as a potential hair loss treatment, but it was deemed ineffective in humans despite promising results in mice. The conversation concluded that trying it without VPA might be unwise.

The conversation is about finding a source for topical valproic acid for hair regrowth. The user mentions PP405 and the unavailability of products from certain suppliers.

Topical sodium valproate may promote hair growth by inhibiting GSK3β, allowing beta-catenin to proliferate, but it has potential side effects and requires more research. The conversation also mentions skepticism about a product called Vdphlo1, which includes sodium valproate and other ingredients.

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.

Suvomipic, previously known as PP405, is progressing to Phase 3 trials for hair loss treatment. Its effectiveness compared to existing treatments like Minoxidil and Finasteride is still uncertain.
