SN514-066b Enzyme in Deep Partial Thickness Burns

Description

The design of the study is a sequential rising dose to the maximum tolerated dose, in which each subject will be exposed to only one concentration of the test article. Dose limiting toxicities are defined as “Severe” or CTCAE v5 Grade 3 or higher adverse events. This study in burn patients is designed to apply SN514-066b over 25 cm2 (0.14% TBSA for a 1.73 m2 adult) up to 500 cm2 (2.9%), at sequentially rising concentrations of 0.1%, 0.2%, 0.4% and 0.8% (< 1.0 mg/cm2). The highest exposure would be 0.8% (8 g per 100 cc of gel) over 2.9% of 1.73 m2 = 800 mg or 11.4 mg/kg applied topically (70 kg patient).
