Official title

A Phase 1, First-In-Human, Randomized, Double-Blind, Placebo-Controlled, Single Dose-Escalation Study to Evaluate the Safety and Pharmacokinetics of Single Oral Doses of VT-1598 in Healthy Adult Subjects

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose study in healthy adult subjects ages 18 - 45 years inclusive. It is designed to evaluate the safety and PK of single oral doses of VT-1598. Forty-eight subjects will be enrolled in the study at 1 site in the US and randomized to receive either VT-1598 or placebo in 6 dosage cohorts (five fasted cohorts and one fed cohort). Each cohort will have 8 subjects; 6 subjects will receive a single oral dose of VT-1598 and 2 subjects will receive matching placebo. Cohorts 1 - 5 will include 2 sentinel subjects randomized to different treatments. Cohort 6 (receiving treatment after being fed a high-calorie, high-fat meal) will not include sentinel subjects. Subjects will be admitted to the study site before dosing and remain at the study site for safety monitoring and PK assessments for at least 72 hours post-dose. Subjects will return to the study site on study Days 7, 14, and 21 for outpatient safety monitoring and PK assessments. There are no formal hypotheses being tested in this Phase 1 trial study. The primary objectives of this study are 1) to determine the safety of single-ascending oral doses of VT-1598 in healthy adult subjects in a fasted state, and 2) to determine the safety of single oral dose of VT-1598 in healthy adult subjects in a fed state.
