  10. Subjects with any clinically significant abnormality following review of pre-study laboratory data and full physical examination
  11. Subjects who are taking or have taken known anticoagulants:

    1. Blood thinners (e.g., coumadin, rivaroxaban, apixaban) within 2 months prior to day 0
    2. Others such as aspirin or aspirin containing products, Non-steroidal anti-inflammatory drugs (NSAIDs), vitamin E, fish oil within 14 days prior to day 0.
  12. Subjects taking systemic or topical steroids within 4 weeks of Day 0
  13. Subjects with excessive alcohol use, defined as >28 units of alcohol per week (1unit = 8 g alcohol, 1shot spirits, half- pint beer, or 5 oz wine)
  14. Subjects who have evidence of drug abuse
  15. Subjects who are known to have or had serum hepatitis or who are carriers of the hepatitis B surface antigen per medical history

  17. Subjects treated with an investigational drug or device within 30 days prior to day 0
  18. Any condition or situation that, in the investigator's opinion, may put the subject at significant risk, or may significantly interfere with the subject's participation in the study

Arm Description

Injection of SLI-F06 on Treatment Day 0, immediately after wound closure: Formulation buffer (control) 3.75 mg SLI-F06 total dose per wound (1X) 7.5 mg SLI-F06 total dose per wound (2X) 15 mg SLI-F06 total dose per wound (4X)

Injection of SLI-F06 on Treatment Day 0, immediately after wound closure and on Days 1, 2, 3, 4: Formulation buffer (control) 3.75 mg SLI-F06 total dose per wound (1X) 7.5 mg SLI-F06 total dose per wound (2X) 15 mg SLI-F06 total dose per wound (4X)

Injection of SLI-F06 on Treatment Day 0, immediately after wound closure and then 3 hours after for wounds dosed twice: Formulation buffer (control) once 7.5 mg SLI-F06 total dose per wound (2X) once 3.75 mg SLI-F06 dose per wound (1X) twice, total dose 7.5 mg 7.5 mg SLI-F06 total dose per wound (2X), total dose 15 mg

Outcomes

Primary Outcome Measures

Change in Scarless Labs Observer Scale
Exploratory scale for observer to assess different scar parameters, including Surface Area, Elevation / Depression, Relief, Thickness, Pliability, Vascularity and Pigmentation. The observer then makes an Overall global assessment (scale 0 to -3) of the scar based on the clinical assessment of the scar parameters. All parameters are assessed on a scale of 0-3 (except pigmentation, -3 [hypo] to +3 [hyper]), where 0 correlates to a scar that is indistinguishable from normal skin with greater deviation from 0 correlating with more severe scar. The observer creates a forced rank between scars on the upper and lower back based on best (1) to worst (4) cosmetically.

Secondary Outcome Measures

Patient and Observer Scar Assessment Scale (POSAS) Observer Scale
Established scar scale with observer rating of 1 (normal skin) to 10 (worst scar imaginable) for 6 different parameters (vascularity, pigmentation, thickness, relief, pliability, surface area) and overall opinion rated on the same 1-10 scale. The sum of these scores is added for a total value with a higher number being worse.
Scarless Labs Patient Scale
Exploratory scale for subjects to assess different scar parameters, with 0 being no difference in pain or itching of the scar compared with normal skin and -3 being severe or worse. Patients then select a face on a modified Wong-Baker scale for their overall opinion of the scar.

5. Study Description

Brief Summary
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
Detailed Description
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.
