What this trial studies

This observational study aims to collect clinical data on the efficacy and safety of letermovir for preventing cytomegalovirus (CMV) infection in patients who have undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). Participants will be categorized into high-risk and intermediate-risk groups based on specific risk factors for CMV infection, with letermovir prophylaxis initiated at different times depending on their risk status. Blood samples will be monitored for CMV viremia using RT-qPCR until 100 days post-transplantation to assess the effectiveness of the treatment regimen.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 14 years and older who have undergone allo-HSCT and have positive CMV serology.

Not a fit: Patients with severe hepatic impairment, low creatinine clearance, or those currently receiving antiviral medications for CMV may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of CMV infections in patients after stem cell transplantation, improving their overall health outcomes.

How similar studies have performed: Other studies have shown promising results with letermovir for CMV prevention, indicating that this approach is supported by prior research.
