Study to Evaluate Efficacy of OLX10010 in Reducing Recurrence of Hypertrophic Scarring After Scar Revision Surgery
Completed · Phase 2
Conditions studied: Hypertrophic Scar
In brief
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.

- Undergoing elective hypertrophic scar revision surgery
- Serum pregnancy test negative for females of childbearing potential
- Males and females of child-bearing potential (e.g., not post-menopausal for at least one year or surgically sterile) must agree to use effective contraception starting at the Screening Visit and continuing until 14 days after the last dose of OLX10010.

You may not qualify if…
- BMI greater than 32 kg/m2. Exceptions to this criteria can be granted for patients just over this value per PI's discretion

- End-stage renal disease or severe renal impairment as indicated by serum creatinine > 2.5 mg/dL
- Tanning (natural or artificial) within 14 days prior to the screening visit or unwilling to abstain from natural or artificial tanning for four weeks after surgery. Tanning is not recommended for the remainder of the study but will not be an exclusion criteria or reason for early termination.
- Hypertrophic scar treatment within 12 weeks prior to the screening visit, excluding scar revision surgery

- Use of tobacco or nicotine-containing products during study participation (Screening Visit through last follow-up visit)
- Female patients who are pregnant or breastfeeding
- Participation in any experimental drug or device study within 30 days prior to the screening visit
- Any clinically significant finding, in the judgement of the treating investigator, that would place the subject at health risk, impact the study, or affect the completion of the study.
