RECOVER-VITAL: A Platform Protocol for Evaluation of Interventions for Viral Persistence, Viral Reactivation, and Immune Dysregulation in Post-Acute Sequelae of SARS-CoV-2 Infection (PASC)

In Brief

A Phase 2 clinical trial evaluating Paxlovid, Ritonavir, and 1 other intervention for Long COVID-19 and Long COVID. Completed, enrolled 964 participants across 1 site.

Detailed Summary

This is an appendix of master protocol (NCT05595369) designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This sub-study is a prospective, multi-center, double-blind, randomized, controlled trial evaluating nirmatrelvir/ritonavir (Paxlovid) in two dosing durations for the treatment of Post-Acute Sequelae of SARS-CoV-2 Infection (PASC). The study is evaluating potential mechanisms of action, efficacy, and safety of antivirals and other therapeutics in individuals with PASC, according to the platform protocol objectives. The hypothesis is that persistent viral infection and/or overactive/chronic immune response and inflammation are underlying contributors to PASC and that antiviral and other applicable therapies may result in viral clearance or decreased inflammation and improvement in PASC symptoms.
