A First-in-Human SAD/MAD Study to Evaluate Safety, Tolerability and PK of ENC0653 Ointment in Healthy Adult Subjects

Официальное название

A Phase 1 Randomized, Double-Blind, Single-Center, Placebo-Controlled Single Ascending Dose and Multiple Ascending Dose (SAD/MAD) Study by Topical Dermal Administration to Evaluate the Safety, Tolerability, and Pharmacokinetics of ENC0653 Ointment in Healthy Adult Subjects

Обзор

This is a FIH, randomized, double-blind, single-center, placebo-controlled, dose -escalation clinical study to evaluate the safety, tolerability and pharmacokinetics of ENC0653 ointment following single and multiple topical dermal administration in healthy adult subjects. Up to 56 subjects will be enrolled at a single site in up to 4 cohorts in Part A (SAD study), and up to 3 cohorts in Part B (MAD study). Part A is for the single dose use of IP, while Part B is twice-daily use for 7 consecutive days and once daily use on Day 8. Each cohort will include 8 subjects (6 receiving ENC0653 ointment and 2 receiving placebo ointment). Dosing will be escalated on a review of safety, tolerability, and available PK data by a Safety Review Committee (SRC).
