Brief Summary

A Phase 2 double-blind, multi-site, placebo-controlled, parallel-group design to assess the efficacy, safety and dose-response characterisation of STS-01 for the treatment of mild- moderate alopecia areata.

Detailed Description

STS-01 is being developed to address the need for an effective, safe and convenient non-steroidal topical treatment for mild-moderate alopecia areata. The product builds on a mechanism with a well-established safety profile in dermatology, and existing evidence of its effectiveness in this condition through targeting key relevant cytokines. STS-01 has been modified to maximise the effectiveness of this mechanism and offer a cosmetically elegant topical cream. The study aims to assess the effectiveness, safety and dose-response characteristics of STS-01 for the treatment of mild-moderate alopecia areata.
