Abstract

Data on the treatment of pediatric patients with brentuximab vedotin are limited. The aims of the present study were to assess the safety and tolerability of brentuximab vedotin in Japanese children with relapsed or refractory Hodgkin’s lymphoma (HL) or systemic anaplastic large-cell lymphoma (sALCL). Pediatric patients, aged 2–17 years, with relapsed or refractory HL or sALCL were recruited. Brentuximab vedotin were administered at 1.8 mg/kg via intravenous infusion once every 3 weeks. Primary endpoints were dose-limiting toxicity and safety. Between September 2016, and March 2018, six patients (median age 11.5, range 5–14 years), four with relapsed or refractory HL and two with relapsed or refractory sALCL were enrolled. Dose limiting toxicity was not observed in any of the six patients. Although three of six patients (50%) experienced at least one grade ≥ 3 adverse event, no patient experienced a serious adverse event. The pharmacokinetic profile of brentuximab vedotin in pediatric patients was comparable to that reported in adults. The proportion of patients who achieved overall response was 60% (95% confidence interval 14.7–94.7). Brentuximab vedotin at 1.8 mg/kg once every 3 weeks was considered tolerable in children with relapsed or refractory HL or sALCL.
