Official title
Phase 1b, Double-Blind, Placebo-controlled Study of Safety and Efficacy of HST 001 in Male Subjects With Male Pattern Hair Loss
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
HST 001 (also known as hair stimulating complex \[HSC\]) is a mixture of growth factors secreted by human dermal fibroblasts when cultured in proprietary bioreactors which are then harvested and concentrated to specific ranges. In both preclinical studies and in previous clinical trials, HSC has been shown to be safe, with no serious adverse events reported. This protocol design is based on the completed Phase 1 study in women which used a similar investigational product (Study 16-HIS002-US; HSC660), and includes specific objective efficacy endpoints (macrophotography) to measure Target Area Hair Counts (TAHC) after three separate doses of product separated by six weeks (week 0, week 6, week 12) and comparing to placebo treated group
