Dose-Finding, Safety, and Efficacy Study of XVR011 Added to Standard of Care in Patients Hospitalised for COVID-19

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04884295
Recruitment Status : Terminated (The sponsor does not intend to start Part 2 (Phase 2) due to change in company strategy for phase 2 design. This early end of trial is not due to reasons of safety or lack of efficacy. Part 1 (Phase 1) is completed as per protocol.)

Brief Summary:

This is a 2 part study where the first part (Phase 1) evaluates the safety of XVR011 and aims to identify the recommended Phase 2 dose. The second part (Phase 2) follows after the part 1 and evaluates whether XVR011 added to standard of care in patients hospitalised for mild to moderate COVID-19 is a safe, well tolerated, and effective treatment.

Part 1 (Phase 1) is completed as per protocol. The sponsor does not intend to start Part 2 (Phase 2) due to change in company strategy for phase 2 design.
