Early antiviral treatment to prevent long COVID

Official title: Early antiviral treatment to prevent viral persistence and inflammation as drivers of Long COVID: a proof-of-concept mechanistic trial

Funded at University of California, San Francisco · NIH-11329178 · Data updated 2026-11-12

A proof-of-concept study will test whether starting a 14-day oral antiviral early in COVID-19 can prevent the long-term persistence of the virus and chronic inflammation that lead to Long COVID.

Who could benefit from this research

Could help

Adults with acute COVID-19 who can safely take an oral antiviral and participate in home-based monitoring.

Less likely to help

Individuals with contraindications to antivirals, those not at risk of persistent infection, or those who do not complete the treatment course may see little or no benefit.

What this research studies

This study will enroll participants with acute COVID-19 in a single center and randomize them to receive a tissue-penetrant oral antiviral for 14 days or usual care. By tracking viral load, viral persistence, and inflammatory markers over time, researchers aim to understand if early antiviral treatment can reduce long-term health problems. The trial is home-based, allowing participants to stay at home while monitoring symptoms and biomarkers. If successful, it could point to a simple strategy to lower the risk of chronic post‑COVID conditions.

Why it matters

Potential benefit: If successful, the approach could reduce the chances of developing Long COVID and related complications by limiting viral persistence and inflammation.

How similar studies have gone: Previous work suggests that reducing early viral load may influence long-term outcomes, but this proof-of-concept trial seeks direct evidence in humans.
