Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a confirmed history of COVID-19 and ongoing symptoms consistent with PACS.

Probably not a fit

Patients who have not experienced COVID-19 or those with alternative diagnoses explaining their symptoms may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the safety and efficacy of anakinra, an anti-inflammatory medication, in treating patients suffering from Post-Acute COVID Syndrome (PACS). The study will involve a randomized, controlled approach where participants will receive either anakinra or a placebo. Improvement will be measured using a composite endpoint that evaluates the reversal of PACS progression. The trial is designed to gather insights into the immune dysregulation associated with long COVID and its potential treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate the debilitating symptoms of long COVID, improving patients' quality of life.

How similar studies have gone: Previous studies, such as the SAVE-MORE trial, have shown promising results in reducing PACS incidence with similar treatment approaches.
