Study of EPI-001 in Patients With Androgenetic Alopecia
Phase I/IIa Study to Evaluate the Safety, Tolerability, and Efficacy of EPI-001 in Patients With Androgenetic Alopecia
This is a Phase I/IIa clinical study to evaluate the safety, tolerability, and preliminary efficacy of EPI-001 in patients with androgenetic alopecia.
In the Phase I portion, a traditional 3+3 dose-escalation design will be used to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of EPI-001. Subjects will be followed for up to 24 weeks after administration.
In the Phase IIa portion, subjects will be randomized in a 2:1 ratio to receive either EPI-001 or placebo. Safety and efficacy will be evaluated through hair count assessment, hair diameter measurement, clinical photography, investigator assessment, expert panel assessment, and subject self-assessment during a follow-up period of up to 48 weeks.

Detaljerad beskrivning
Androgenetic alopecia (AGA) is one of the most common forms of hair loss in both men and women and is characterized by progressive hair follicle miniaturization associated with androgen sensitivity and genetic predisposition. Current treatment options for AGA are limited and may not provide sufficient therapeutic benefit for all patients.
EPI-001 is an autologous dermal papilla cell therapy intended for the treatment of androgenetic alopecia. This study is designed to evaluate the safety, tolerability, and efficacy of EPI-001 in subjects with androgenetic alopecia.
This study consists of two parts: a Phase I dose-escalation study and a Phase IIa dose-expansion study.
In the Phase I portion, subjects will receive a single administration of EPI-001 using a traditional 3+3 dose-escalation design to evaluate dose-limiting toxicity (DLT), determine the maximum tolerated dose (MTD), and establish the recommended Phase 2 dose (RP2D). Subjects will be followed for up to 24 weeks after administration.
In the Phase IIa portion, eligible subjects will be randomized in a 2:1 ratio to receive either EPI-001 at the RP2D or placebo. The study will evaluate efficacy through changes in total hair count and hair diameter, as well as investigator assessment, expert panel assessment based on clinical photographs, and subject self-assessment questionnaires. Subjects will undergo follow-up assessments for up to 48 weeks after administration.

Investigator Assessment of Hair Growth Improvement Based on Clinical Photographs Using a 7-Point Scale
Tidsram: Phase I: Weeks 4, 12, and 24; Phase IIa: Weeks 12, 24, 36, and 48
|
Investigators assess hair growth improvement by comparing clinical photographs with baseline photographs using a 7-point scale ranging from -3 (greatly decreased) to +3 (greatly increased).
Higher scores indicate greater improvement.

Subject Self-Assessment of Hair Growth Improvement Using a 7-Point Questionnaire Scale
Tidsram: Phase I: Weeks 4, 12, and 24; Phase IIa: Weeks 12, 24, 36, and 48
|
Participants assess overall hair growth improvement using a questionnaire evaluating whether hair became fuller, reduction in hair shedding, increase in hair thickness, improvement in hair gloss and elasticity, improvement in overall scalp appearance, and increase in hair growth rate.
Each item is scored on a 7-point scale ranging from -3 (greatly worsened) to +3 (greatly improved).
Higher scores indicate greater perceived improvement.
