Evaluation of SARS-CoV-2 Entry, Inflammation, and New Therapeutics in Human Lung Tissue Cells

The trial for TDM-105795 has been completed, and it was in phase 2A. The discussion seeks input on the next phases, 2B or 3, based on safety and efficacy.

The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.

RU58841 is absorbed systemically in humans, contradicting claims it stays local, but no harm is proven. Alternatives like CB-03-01 or KX-826, especially with finasteride, are suggested for safety.

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.

Setipiprant, a PGD2 inhibitor, and RepliCel, a cell transplantation technology, are being explored as potential hair loss treatments. Current mainstream treatments like Minoxidil and Finasteride have limitations due to side effects and efficacy.

People are discussing the anticipated release of PP405 phase 2a results, expected by the end of March, with some skepticism about its effectiveness. There is cautious optimism due to past experiences with similar treatments like Breezula, despite concerns about the lack of presentation at the AAD 2026 conference.
