A Safety, Tolerability and Pharmacokinetic Study of cP12 in Adults With Up To 10% Total Body Surface Area Burns

This is a Phase 2a, open-label, single-dose study to evaluate the safety, tolerability, and PK profile of cP12 in 6 male and female subjects with thermal burns of up to and including 10% TBSA. Enrolled subjects must have at least 1% superficial (epidermal), superficial partial-thickness, or deep partial-thickness burns. With the exception of the burns, subjects should be healthy and will be assessed to rule out smoke inhalation and other injuries. Vital signs prior to dosing must be stable and an electrocardiogram (ECG) must not show clinically significant abnormalities.

The target burn used in this study will be selected based on a burn classification description conducted prior to dosing with cP12. The selected burn must be superficial (epidermal), superficial partial-thickness, or deep partial-thickness and must not be a circumferential burn.

In the absence of burn-specific, validated assessment tools, NeoMatrix has developed scales to characterize the burn and surrounding tissues for this trial. Burn assessments will include erythema, capillary refill, blisters, and edema/swelling. In this trial, the target burn and all other burns of each subject will be assessed.

Eligible subjects will receive a single administration of 0.01 mg/kg cP12. Study drug will be administered over approximately 30 minutes by intravenous (IV) infusion with the subject in a supine position, and the infusion is to be initiated and completed within 2 to 24 hours after the burn has occurred. The subject is to remain in the supine position for 60 minutes from the start of study drug infusion (ie, during the 30-minute infusion and for 30 minutes after study drug infusion).

Vital signs, ECGs, and blood samples and urine samples will be obtained at screening and at several time points during the study for safety evaluation. Burn and pain assessments will be completed at specified times.

Subjects will remain at the clinical site for at least 6 hours post infusion for the purpose of safety monitoring and evaluation of other study assessments. Subsequent evaluations will be performed at the clinical site 3 (±1) days and 7 (±2) days after dosing.

Subjects will return to the clinical site 14 (±2) days after dosing for an End-of-Study visit.
