Preclinical Challenges in Proton Minibeam Radiotherapy: Physics and Biomedical Aspects

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.

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.

PP405 is being discussed as a potential treatment for hair loss, with uncertainty about its effectiveness compared to existing treatments like finasteride, dutasteride, and minoxidil. There is cautious optimism, but its impact on hair transplants remains unclear.

Pelage is delaying the start of phase 3 trials for PP405 to 2026 due to necessary regulatory processes, despite having $120 million in funding. Users discuss the potential of PP405 for hair regrowth, with some expressing skepticism and others hopeful for new treatments like Breezula.

A satirical post where someone claims to have developed a radioactive isotope scalp serum using Polonium-210 that outperforms Minoxidil and finasteride for hair regrowth. The serum reportedly stimulates DNA repair in hair follicles, leading to significant hair density increase, but the post is met with skepticism and concerns about safety.

The conversation discusses the potential benefits and risks of participating in the PP405 hair loss trials, emphasizing that those using Minoxidil or finasteride are less likely to be accepted. Participants are interested in the trial as it offers hope for effective treatment without the side effects associated with current medications.
