Is this trial a fit for you?

Likely a good fit

Children who undergo myeloablative allogeneic HSCT, have not had CMV reactivation before prophylaxis starts, and have no history of immunoglobulin-related adverse reactions or post-HSCT adoptive cellular therapy.

Probably not a fit

Patients with CMV reactivation before prophylaxis, known immunoglobulin hypersensitivity, or who receive adoptive cellular immunotherapy after transplant are unlikely to benefit from this approach.

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

What this trial studies

Children who receive myeloablative allogeneic HSCT at IRCCS Burlo Garofolo are given biweekly CMV-specific immunoglobulin (Cytomegatect/Megalotect) starting on day 3 of conditioning and continuing during hospitalization and at admissions until CD4+ recovery. CMV DNAemia is monitored by real-time PCR twice weekly in hospital and weekly after discharge, with short 3–5 day "boost" doses if DNAemia appears based on risk. Key outcomes include overall survival, relapse-related mortality, graft-versus-host disease, immune reconstitution by CD4+ counts, and CMV reactivation rates, with follow-up for at least 12 months. The observational protocol enrolls children without prior CMV reactivation before prophylaxis and excludes those with immunoglobulin hypersensitivity or who receive adoptive cellular post-HSCT therapy.

Why it matters

Potential benefit: If successful, this prophylaxis could lower CMV reactivation rates, reduce transplant-related complications, and improve survival after pediatric allo-HSCT.

How similar studies have gone: Some prior studies and observational reports suggest high CMV-neutralizing antibody levels may be protective, but evidence specifically in pediatric allo-HSCT is mixed and not definitive.
