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)

Kanecia Obie Zimmerman·interventional·Posted Oct 27, 2022·Updated Dec 2, 2025

In Brief

A Phase 2 clinical trial evaluating Experimental: Paxlovid 25 day dosing, Experimental: Paxlovid 15 day dosing, and 1 other intervention for Long COVID and Long Covid19. Completed, enrolled 963 participants across 69 sites in 2 countries.

Detailed Summary

This study is a platform protocol 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 protocol is a prospective, multi-center, multi-arm, double-blind, randomized, controlled platform trial with different interventions organized as appendices to the protocol. Each appendix (or sub-study) evaluates 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, viral reactivation, 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.
