Interventions
Drug: Placebo
Registration Number
NCT04349761
Lead Sponsor
MyMD Pharmaceuticals, Inc.
Brief Summary

Double-blind, placebo-controlled, First-in-Human, single ascending-dose study. Approximately 40 healthy adult male subjects will be given a single capsule of MYMD1 to determine its safety, how well it is tolerated, how the body acts on the experimental drug, and how the experimental drug acts on the body. This will be based on blood and urine sample analysis and other physical measurements.

Detailed Description

A single-center, double-blind, placebo-controlled, first-in-human, single ascending-dose study to evaluate the safety, tolerability, and pharmacokinetics of single oral dose capsules of MYMD1 in healthy male adult subjects. Each subject will participate in the study for approximately 7 weeks, including a Screening period of up to 30 days, a confinement period of 4 days, and a follow-up period of approximately 2 weeks. In each cohort, 8 subjects will be administered a single dose of either MYMD1 (N=6 in each cohort) or Placebo (N=2 in each cohort), under fasted conditions, and each subject will participate in only 1 of the 5 cohorts during the study. Anticipated dosing levels will be 5mg (Cohort 1), 10mg (Cohort 2), 15mg (Cohort 3), 20mg (Cohort 4), and 25mg (Cohort 5). Sentinel dosing will be used to initiate each cohort, and the first 2 subjects will be randomized 1:1 to receive either MYMD1 or Placebo. The remaining subjects will be dosed 5:1 to receive either MYMD1 or Placebo, respectively.
