Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.
PP405 is a topical gel being tested for hair regrowth in adults with androgenetic alopecia. Volunteers aged 18-55 are needed for a 16-week trial in several US locations.
A compound called MTP3 from the Monoterpene family was found to be safe and highly effective at treating hair loss by inhibiting the FGF5 gene, but its identity is undisclosed for commercial reasons. No specific treatments like Minoxidil, finasteride, or RU58841 were discussed.
The conversation discusses positive initial trial results for GT20029, a topical compound for hair loss that degrades androgen receptors, potentially requiring only weekly application. Participants express hope for this treatment to be more effective and convenient than current options like Minoxidil, Finasteride, and RU58841.
Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.
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.
Pelage Pharmaceutical raised $120 million to continue research on PP405, a promising hair loss treatment that showed a 20% increase in hair density in 31% of men during a Phase 2a trial. The treatment was well-tolerated, with no systemic absorption, and Phase 3 trials are planned for 2026.
Kintor Pharma finished enrolling and dosing participants in a Phase I trial for a hair loss treatment called AR-PROTAC (GT20029). The effectiveness of another drug, pyrilutamide (KX-826), for hair loss will be clearer after a Phase 2 trial expected to complete in January 2023.
The conversation discusses the approval of Kintor Pharmaceutical's AR-PROTAC (GT20029) for clinical trials in China for acne and androgenic alopecia. One user expresses optimism about new treatments being developed and seeks clarification on how the new drug works, specifically if it temporarily degrades the AR protein to reduce DHT sensitivity in hair follicles.
PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.
The conversation discusses GT20029, a compound by Kintor Pharma that degrades androgen receptors and is in trials, with potential as a hair loss cure. Another promising treatment mentioned is an antibody that blocks prolactin and has shown positive results in macaques.
Peptides, specifically GHK-Cu, are being considered for hair growth benefits, such as increasing blood flow to the scalp and preventing hair follicle shrinkage. A user reported starting GHK-Cu after hearing it made a friend's hair thicker.
TGF-B affects hair growth, both causing stem cell division and death depending on amounts. Amplifica's treatment injects Scube3 to increase TGF-B for hair growth.
PTD-DBM is being explored for hair regrowth by targeting CXXC5, with clinical trials expected after pre-clinical studies. Users express anticipation and skepticism about its effectiveness.
RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.
A peptide-based hair loss treatment, PP405, reportedly increased hair density by 62% in 90 days, but these claims are unverified and met with skepticism. Users compared PP405 to Minoxidil and Finasteride, expressing doubts about its effectiveness without more evidence.
P5P supplementation helped reverse finasteride side effects, particularly by lowering prolactin levels and restoring sensitivity. The user experienced significant improvement within a day and full recovery in a few days.
MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.
PP405, a potential hair loss treatment, is facing delays in releasing Phase 2 results, causing frustration among users who compare it to past failed treatments. Despite skepticism, some remain hopeful about PP405's future, while others discuss alternative treatments like Clascoterone and its expected market release.
HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.
Using finasteride and peptides, including GHK-Cu, improved hair thickness and regrowth. The user also used a KLOW blend and CJC/IPA for better sleep and recovery.
A user was prescribed betamethasone dipropionate spray for a receding hairline, which caused skin peeling and depigmentation. They stopped using it and are considering alternatives like BPC-157/TB-500 for healing.
A female user with alopecia is researching peptide usage, specifically ghk-cu, for hair loss. Other users shared mixed experiences with copper treatments, noting some success with topical application.
PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.
Copper peptide topical is being discussed for hair health, with some users noting it may improve hair volume. There is uncertainty about its effectiveness against hair loss.
PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.
Peptides are being discussed for potential hair loss treatments, but most are not proven effective for this purpose. Minoxidil and finasteride are mentioned as more reliable options for hair growth.
TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.
A 30-year-old man experienced significant hair loss after starting testosterone replacement therapy (TRT), which did not improve with daily finasteride and minoxidil. He is considering restarting TRT and is seeking advice on using pyrilutamide or RU58841 to prevent further hair loss.
