Safety and Pharmacokinetics of VT-1598

• Status: Recruiting
• Trial end date: 2021-10-29
• Target enrollment: 0
• Participant gender: All

Summary

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.

*As defined by need for medical intervention that lead to a change in medications and/or required hospitalization, surgery/procedure, or ED/urgent care visit

4. History of psychiatric condition that has required hospitalization in the last 5 years or patient is considered unstable by study investigator.

5. Any condition that in the opinion of the Investigator could significantly impact drug absorption, distribution, or elimination.

6. Any out of normal range laboratory value* at screening or enrollment.

*A laboratory value that is Grade 1 (with the exception of alanine aminotransferase (ALT), aspartate aminotransferase (AST), Total bilirubin, hemoglobin or serum creatinine) will be allowed if not considered to be clinically significant by the investigator.
