VNRX-9945 Safety and Pharmacokinetics in Healthy Adult Volunteers

Phase 1 Study to Evaluate the Safety and Pharmacokinetics of Single and Multiple Ascending Doses of VNRX-9945 in Healthy Adult Volunteers

This is a 2-part first-in-human dose-ranging study to evaluate the safety and pharmacokinetics of escalating doses of VNRX-9945.

Study Overview

• Status: Terminated
• Conditions: Healthy Volunteers
• Intervention / Treatment: Drug: VNRX-9945; Drug: Placebo for VNRX-9945

Detailed Description

In Part 1, subjects will receive a single dose of VNRX-9945 or placebo. Subjects enrolled in the food effect cohort will receive a dose in a fasted and fed state (total 2 doses) of VNRX-9945 or placebo following an appropriate washout period between the doses. In Part 2, subjects will receive doses of VNRX-9945 or placebo daily for 14 days.
