Официальное название

A Randomized, Within Subject Controlled, Dose Regimen Study of SLI-F06 in Healthy Volunteers for Improvement in Scar Appearance

Обзор

Multi-center, dose-regimen, double-blind study evaluating the safety and efficacy of 4 doses of SLI-F06 compared with vehicle for improvement in scar appearance

Подробное описание

The is a Phase IIa dose-regimen study of small punch biopsy scars created on the upper and lower back of healthy patients. All excisions will be randomized to treatment with vehicle or 4 doses of SLI-F06 drug product. Patients will be divided into 3 cohorts, with Cohort B receiving the same doses as Cohort A but daily for a total of 5 days. Cohort C will receive up to twice the concentration of Cohort A potentially divided into 2 doses, with both cohorts treated only on treatment Day 0. Scars will be assessed for improvement by both the investigator and the patient at follow-up visits over 6-9 months.

Duration of study-approximately 7-10 months.
