Key Points• Brincidofovir has superior antiadenoviral activity and safety profile compared with cidofovir.• Brincidofovir is highly efficacious in controlling adenoviremia during the lymphopenic phase of HCT.Cidofovir is preemptively used for controlling adenoviremia and preventing disseminated viral disease in hematopoietic cell transplant (HCT) recipients but does not lead to resolution of viremia without T-cell immune-reconstitution. The lipid-conjugated prodrug of cidofovir, brincidofovir, has improved oral bioavailability and achieves higher intracellular concentrations of active drug. We present retrospective multicenter data comparing the kinetics of viremia and toxicities following preemptive treatment with and brincidofovir in children and adolescents diagnosed with HCT-related adenoviremia. Forty-one episodes (18 5 brincidofovir; 23 5 cidofovir) of antiviral therapy were observed in 27 patients. The 2 groups had comparable immune-reconstitution and viral burden. Major ( ‡2 log-reduction in 2 weeks; n 5 13) and minor ( ‡1 to £2 log-reduction in 2 weeks; n 5 2) virological responses were observed in 15 (83%) brincidofovir episodes compared to only 2 (9%) major virological responses with cidofovir (P < .0001). Brincidofovir mediated major responses in 9 of 11 cidofovir-unresponsive patients and resulted in complete responses (CR) despite significant lymphopenia (Brincidofovir vs cidofovir; CR 5 13 (80%) vs 8 (35%); median lymphocyte count 5 320/ml vs 910/ml; P < .05). One patient experienced abdominal cramps and diarrhea necessitating interruption of brincidofovir and none developed nephrotoxicity with brincidofovir. Thus, brincidofovir is well-tolerated and highly efficacious in controlling adenoviremia during the lymphopenic phase of
Asymptomatic young adult survivors of childhood ALL demonstrate a biologic profile of chronic inflammation and telomere attrition, consistent with an early onset of cellular processes that drive accelerated aging. These processes may explain the premature development of age-related chronic conditions in childhood cancer survivors. Understanding their molecular basis may facilitate targeted interventions to disrupt the accelerated aging process and its long-term impact on overall health.
