An Accessible Pharmacodynamic Transcriptional Biomarker for Notch Target Engagement

SCUBE3, a protein linked to hair growth in moles, was discovered over 25 years ago and is being developed by Amplifica for potential hair loss treatment. Concerns exist about SCUBE3's association with cancer, as it is a protein that promotes cell growth, which could potentially trigger cancer development if used for hair growth therapy.

A potential non-invasive topical treatment targeting the WNT Signaling Pathway for hair regeneration is being researched, with positive results on human hair follicle cells. Current effective treatments for hair loss include Minoxidil, finasteride, and hair transplantation.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

Mallia Aesthetics has developed MAL-838, a hormone-free product derived from sCD83, which stimulates hair growth without disrupting the skin microbiome. sCD83 promotes hair growth by activating hair follicles and preventing cell death, offering a localized treatment without systemic side effects.

ABS-201 shows promise for male hair regrowth by blocking the prolactin receptor, with higher expected efficacy than current treatments. The discussion also covers dosing differences between macaques and humans for hmi115, highlighting a significant dosage disparity.

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.
