Umbilical cord mesenchymal stem cell exosome treatment for male pattern hair loss in young men

A Randomized Controlled Clinical Study on the Treatment of Androgenetic Alopecia in Young Men With Umbilical Cord Mesenchymal Stem Cell Exosomes

PHASE1; PHASE2 · Shenzhen People's Hospital · NCT07203599

This trial will test whether injections of umbilical cord mesenchymal stem cell exosomes can regrow hair or slow hair loss in men aged 18–35 with androgenic alopecia compared with topical 5% minoxidil.

What this trial studies

The study has a Phase I dose-escalation portion to identify a safe and tolerable injection dose of human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-sEV) and a Phase II randomized controlled portion comparing the selected dose against topical 5% minoxidil. In Phase I, participants are assigned to one of three dosing groups to determine appropriate injection density per square centimeter of hair loss. Phase II randomizes eligible participants to receive either hUCMSC-sEV injections or the comparator and follows hair growth and safety outcomes over a defined follow-up period. Safety monitoring will include adverse event reporting and clinical exams, while efficacy will be measured by standardized hair counts, photographic assessment, and scalp evaluations.

Who should consider this trial

Good fit: Men aged 18–35 with clinically diagnosed androgenic alopecia (Hamilton‑Norwood III–V) who can consent and meet the trial's health and medication restrictions are ideal candidates.

Not a fit: Patients outside the age range, with other scalp diseases, severe systemic illness, recent use of hair-loss drugs, or contraindicated medications are unlikely to qualify or derive benefit from this protocol.

Why it matters

Potential benefit: If successful, the treatment could offer a new option to stimulate hair regrowth or slow progression of male pattern hair loss with a biologic regenerative approach.

How similar studies have performed: Preclinical studies and small early-phase clinical reports suggest stem cell-derived exosomes may promote hair growth, but large randomized clinical data are currently limited.
