Brief Summary

Many people suffer from alopecia, which is caused by hereditary factors, emotional stress, and psychiatric disorders. There are devastating physical and psychological consequences as a result. Exosomes are isolated from donated human mesenchymal stem cells and purified using specific processing. This study is a randomized, double-blind, dose-escalation clinical trial designed to evaluate the efficacy and safety of exosomes therapy for alopecia.

Outcome Measures

Primary Outcomes (3)

  • Comparison of localized hair density

    Quantify hair counts within designated 1.5 cm × 1.5 cm fixed areas in both the study area and control area, and compare the localized hair density (hair/cm²) between the two areas.

    3rd month after 3 treatments

  • Safety Assessment

    Incidence of treatment emergent adverse events (TEAEs)

    From the initial treatment administration to the subject withdrawal from the study.

  • Comparison of overall hair density

    Evaluate and score overall hair density in both the study area and control area using an 8-level assessment scale, followed by a comparative analysis of the two areas.

    3rd month after 3 treatments

Secondary Outcomes (1)

  • Change of hair density

    3rd and 6st month after 3 treatments

Study Arms (2)

exosomes

EXPERIMENTAL

Subjects will receive 5E8 \~5E9 particles/cm² of exosome therapy in the study area during the dose escalation phase.

Biological: exosomes

PLACEBO COMPARATOR

The control site will receive the same volume of saline as the exosomes administered in the study site.

Other: saline

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects are able to read documents and can sign informed consent.
  • \~75 years old (including the threshold), gender is not limited.
  • The subject's "hair loss grade" meets the following criteria:
  • \) BASP grade: Basic type (M2 to M3, or C2 to C3, or U1 to U3) or special type (V1 to V3, or F1 to F3); 2) For female: Ludwig Grade I to II. Or for male: Hamilton-Norwood Grade III to IV; 3) Hair density by phototrichogram: ≤ 190 hair/cm² ; 4. Hair dryness ≥ 5%; 5. Until withdrawal/completion of the study, subjects agree not to undergo any topical treatment for hair loss and agree to use a neutral shampoo.

You may not qualify if:

  • People with patchy or diffuse baldness, syphilitic alopecia, scarring alopecia, malnutrition, chemotherapy/radiotherapy-induced hair loss.
  • Those with a combination of diseases that have an impact on hair growth.
  • Use of medications, medicated shampoos, or hair care products that may interfere with efficacy evaluation within 3 months prior to screening (oral administration of therapeutic agents for androgenetic alopecia must be discontinued for at least 6 months).
  • Have received scalp radiation and/or laser or surgical therapy within 3 months prior to screening.
  • Participated or are participating in a interventional clinical trial within 3 months.
  • Persons with a history of hereditary alopecia areata.
  • Women who are pregnant or breastfeeding, or male/female subjects whose own/partner's pregnancy is planned within 6 months.
  • Have undergone hair transplantation in the previous 24 months.
  • Individuals testing positive for active infectious diseases or carriers of communicable pathogens.
  • Those with keloid, keloid-prone or hyperplastic scarring.
  • Those who, in the opinion of the investigator, are otherwise unfit to participate in this clinical study.
