Details and patient eligibility

About

Double-blind, placebo-controlled, single ascending and multiple dose study. Approximately 32 healthy adult male and female subjects will be given a single capsule of MYMD1 to determine its safety, tolerability, and pharmacokinetic properties. The study data will guide the establishment of an optimum therapeutic dose.

Full description

A single-center, double-blind, placebo-controlled, single ascending and multiple-dose study to evaluate the safety, tolerability, and pharmacokinetics of a single oral dose of MYMD1 capsule in healthy male and female adult subjects. Each subject will participate in the study for approximately 7-8 weeks, including a Screening period of up to 30 days, a confinement period of 2 or 5 days, and a follow-up period of approximately 5 days. In each of Cohorts 1-3, 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. Subjects in Cohort 4 will be administered either MYMD1 (N=6) or Placebo (N=2) on Days 1, 2, 3, 4, and 5. Each subject will participate in only 1 of the 4 cohorts during the study. Anticipated dosing levels will be 150mg (Cohort 1); 300mg (Cohort 2); 250mg (Cohort 3); and 600mg (Cohort 4).

6. Current smoker or smokeless tobacco user, ie, no use of tobacco within 30 days of study entry.
7. Have participated in any drug or medical device-related clinical study within 30 days of study entry.
8. Have values on standard clinical laboratory assessments that are deemed medically significant (show evidence of untreated significant medical illness or pose a risk of significant intercurrent illness during the study in the opinion of the Investigator).
9. Have any significant medical condition that could in the Investigator's opinion interfere with the study or put the subject at a significant risk. These may include, but not limited to the following: active malignant disease, current use of immune-suppressing drugs, currently taking opioid pain medication, and active seizure disorder.
10. On ECG, QTcF >450 ms or the presence of clinically significant abnormalities as determined by the Investigator (Screening or Day -1).
11. Elevation of BP, ie, supine systolic BP >145 mmHg and/or diastolic BP >92 mmHg, or heart rate >100 beats per minute at rest (Screening or Day -1). Readings that fall outside these ranges will be allowed to enter the study if they are health candidates at the Investigator's discretion.

All subjects will be required to have a negative test prior to check-in. A positive test will result in exclusion from the study.
