Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are Veterans aged 50 and older who are experiencing long-COVID symptoms and are 3-12 months post-COVID-19 diagnosis.

Probably not a fit

Patients with severe comorbid conditions, such as unstable coronary artery disease or severe COPD, may not benefit from this study.

What this trial studies

This study aims to improve the health outcomes of older Veterans suffering from long-COVID by developing rehabilitation therapies that enhance vascular endothelial function. The approach focuses on addressing oxidative stress and inflammation, which are exacerbated by aging and COVID-19. Participants will receive either Mitoquinone or a placebo to evaluate the effectiveness of this treatment in improving symptoms associated with long-COVID, such as fatigue and cognitive deficits. The study will assess the long-term health impacts of COVID-19 and provide evidence-based recommendations for rehabilitation.

Why it matters

Potential benefit: If successful, this study could significantly improve the quality of life and health outcomes for older Veterans recovering from long-COVID.

How similar studies have gone: While there is ongoing research into long-COVID rehabilitation, this specific approach targeting vascular endothelial function with Mito-Q supplementation is relatively novel.
