An open-label, multicenter, single arm study evaluating the efficacy and safety of PRM-001 in the treatment of Crows Feet Lines(CFLs)on the sides of the eyes in Japanese subjects

Basic Information

Recruitment status	Pending
Health condition(s) or Problem(s) studied	Crows Feet Lines
Date of first enrollment	01/06/2026
Target sample size	142
Countries of recruitment
Study type	Interventional
Intervention(s)	PRM-001 would be injected to the intradermal layer of a CFL site with up to 1.0 mL of volume at an injection. The maximum application volume of PRM-001 is 1.0 mL per CFL on the sides of each eye, applied a total of 4 times (3 times at 2-week intervals after the first application), so the maximum application volume for wrinkles under both eyes is 4.0 mL per side (the application volume for each subject is at the PI/ Sub-Is discretion).

Outcome(s)

Primary Outcome

Efficacy endpoints Primary Endpoint: To confirm the achievement of the success criterion that the lower limit of the 95% confidence interval for the improvement rate of LCL severity at 12 weeks after the final administration of PRM-001 (Visit 8) exceeds the performance goal. Safety assessment: Injection related information, Adverse event, Laboratory test, Physical Examinations, Local tolerability assessments

Secondary Outcome

Improvement rate from baseline in LCL severity assessed by IIAI at 2 and 4 weeks, and GAIS(by PI/Sub-I and subjects) and Subject Self-Assessment (SSA) at 2, 4, and 12 weeks after the final PRM-001 injection(Visits 6-8).
