Clinical Trial Summary

A Phase II prospective, randomized, double-blind, placebo controlled and comparative clinical study evaluating hydrogel scar-management modalities for effective management of hyperproliferative scars and keloids.

This is a double-blinded study, which means that neither the evaluating physician nor the subject will know which treatment is administered.

Group selection and assignment will be made at random, with a 2 in 5 chance of receiving a market-approved therapy, and 1 in 5 chance of receiving the placebo. Subjects assigned the placebo-moisturizer will receive a standard hypoallergenic dermatological hydrating cream base. Subjects assigned the silicone gel, will receive a commercially available, active comparator.

Description:

A Phase II prospective, randomized, double-blind, placebo controlled and comparative clinical study evaluating hydrogel scar-management modalities for effective management of hyperproliferative scars and keloids. Unlike raised and, or hyperproliferative scars that result from aberrant wound healing, keloids are the result of inherited genetic mutations in a variety of proteins essential to orchestrated wound repair. Whereas hyperproliferative scars may have shared similar abnormalities throughout the repair of a primary injury, they are not predictors of subsequent scarring following scar revision. Keloids on the other hand will return upon excision, and in some cases larger in size than the excised scar tissue. Current treatment options for keloids as well as hypertrophic scars include intralesional corticosteroids, silicone gel sheeting, compression, surgery and adjuvants to surgery, including radiation and cryotherapy.

Onion skin extract, silicone, and a variety of over-the-counter selfcare product options are available for patients with keloids and hypertrophic scars. Despite market approval, robust efficacy data to substantiate product claims is scarce. At best, comparative studies have been able to demonstrate significance between modalities/products. With only a limited number of investigator initiated studies with scar-patients the advancement in this niche, yet expansive, medical sector has been incremental across decades of research. This study is being undertaken to investigate the efficacy and safety of a FS2- moisturizer, and two market-approved scar topical therapies. The FS2- moisturizer is claimed to be substantially equivalent or superior to market approved Onion skin extract (Mederma), and silicone gel (Kelo-Cote)intended to manage and improve hyperproliferative closed scars. The study builds upon a recent study that investigated safety and efficacy of a petrolatum lotion vs. onion-extract gel vs. placebo in subjects with hypertrophic scars and keloids. There two (2) Study Arms and five (5) Treatment Groups. Treatment Groups consist of: placebo moisturizer cream base, Onion skin extract (Mederma), FS2-moisturizer formulations, silicone gel (Kelo-Cote), and an FS2-silicone gel.

This is a double-blinded study, which means that neither the evaluating physician nor the subject will know which treatment is administered. A separate study team member will administer the treatment, as well as answer questions and discuss any problems prior to starting, and for the duration of, the study.

Subjects will be assigned a Treatment Group from those listed above. Group selection and assignment will be made at random, with a 2 in 5 chance of receiving a market-approved therapy, and 1 in 5 chance of receiving the placebo. Subjects assigned the placebo-moisturizer will receive a standard hypoallergenic dermatological hydrating cream base. Subjects assigned the silicone gel, will receive a commercially available, active comparator.
