Phase 2a Prospective, Randomized, Double-blind, Intra-subject, Placebo-controlled, Proof of Concept Study to Evaluate the Efficacy of OLX10010 as an Adjunct Therapy to Reduce the Recurrence of Hypertrophic Scars After Scar Revision Surgery

Phase 2a, prospective, randomized, double-blind, intra-subject, placebo-controlled, proof of concept study. Approximately twenty subjects will be randomized 1:1 to one of two treatment arms: Arm A: 2.0 mg/cm OLX10010 biweekly (every two weeks) Arm B: 5.0 mg/cm OLX10010 biweekly (every two weeks) Each treatment arm will have approximately 10 subjects. Each subject will receive both active (OLX10010) and control (placebo) treatment post-hypertrophic scar surgery biweekly (every two weeks) for a total of six doses. Dosing will occur post-surgery on Weeks 2, 4, 6, 8, 10, and 12. Post-treatment follow-up visits will occur at Weeks 18 and 24, and a long-term follow-up visit will occur at Month 12. The Patient and Observer Scar Assessment Scale (both physician and patient scales), Stony Brook Scar Evaluation Scale, Vancouver Scar Scale, and a photograph-based visual analog scale by blinded experts will be completed prior to scar revision surgery, at Weeks 2, 8, 12, 18, and 24, and at Month 12. The overall opinion responses on the physician scales of the POSAS at Week 24 will be used for primary endpoint analysis. The total length of the linear hypertrophic scar line will be divided equally for treatment with OLX10010 and placebo, injected intradermally per centimeter (cm). The OLX10010 end and placebo end of the scar line will be separated by a 2 cm or greater distance depending on the scar length. After the Week 24 visit, all data collected will be cleaned and all data management activities will be completed. After the database is frozen/locked, the primary endpoint efficacy analysis will be completed. If at least one of the treatment arms are shown to be appropriate to reduce recurrence of hypertrophic scars, all analyses will be performed. If the efficacy analysis of Arms A and B indicate the study doses are not as effective as expected, the sponsor may decide to add a third arm (Arm C) to explore the weekly dosing regimen. See detailed summary. Subjects in all study arms will continue in the study until their Month 12 visit. After all subjects complete that visit, data are collected, and data management activities are completed, Month 12 data will be analyzed.
