Using MxA to guide antiviral treatment for respiratory viral infections

Application of Myxovirus Resistance Protein a in Antiviral Treatment Guidance of Respiratory Viral Infections

Not applicable Interventional Capital Medical University · NCT06668025

This study is testing if using a special protein called MxA to guide antiviral treatment can help people with respiratory viral infections like influenza and COVID-19 recover faster and have fewer repeat infections compared to standard treatment.

What this trial studies

This pilot randomized controlled trial investigates the effectiveness of Myxovirus Resistance Protein A (MxA)-guided antiviral treatment compared to standard treatment for patients with respiratory viral infections, including influenza and COVID-19. The study aims to determine if using MxA as a biomarker can lead to better clinical outcomes by reducing the recurrence of infections and improving symptom resolution times. Participants will be monitored for 30 days following treatment to assess the impact of the MxA-guided approach on their recovery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a primary diagnosis of influenza or COVID-19, who are currently receiving or are planned to receive antiviral treatment.

Not a fit: Patients who are severely ill, such as those requiring mechanical ventilation or with known immunosuppression, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and personalized antiviral treatments for patients with respiratory viral infections.

How similar studies have performed: While the use of biomarkers in guiding antiviral treatment is a novel approach, similar studies have shown promise in improving treatment outcomes for viral infections.
