Phase 1 Healthy Volunteer Burn Therapy Study

Up to 32 healthy, male and female subjects will be enrolled in this Phase 1, single-center, randomized, double-blind, placebo-controlled, first-in-human study. Eligible subjects will be confined to a Phase 1 unit for approximately 48 hours and receive a one time IV dose of study medication. They will be required to return for a safety follow-up visit one week later.

Doses will be studied sequentially starting with the lowest dose of the investigational drug, cNP8. Each dose cohort will include a total of 6 subjects dosed with cNP8 and 2 subjects dosed with placebo.

A sentinel dosing plan with staggered enrollment will be employed. For each dosing cohort, 2 subjects will be dosed (1 with cNP8 and 1 with placebo) and monitored for serious and/or severe adverse events (AEs). If no serious or severe AEs occur in 24 hours postdose, the remaining 6 subjects in the cohort will be dosed.

Safety evaluations, including laboratory tests, vital sign measurements and electrocardiograms, will be performed at several timepoints throughout the study.
