FDA Approval of Brentuximab Vedotin for Pediatric High-Risk Classical Hodgkin Lymphoma
November 2022: The combination of doxorubicin, vincristine, etoposide, prednisone, and cyclophosphamide with brentuximab vedotin (Adcetris, Seagen, Inc.) has been approved by the Food and Drug Administration for use in children and young adults with high-risk classical Hodgkin lymphoma who have not received treatment in the past (cHL). This is brentuximab vedotin’s first paediatric approval.
Clinical Trial Efficacy and Event-Free Survival Outcomes
A randomised, open-label, actively controlled trial was used to assess effectiveness. Stage IIB with bulk illness in Ann Arbor, Stage IIIB, Stage IVA, and Stage IVB were all classified as high risk. Brentuximab vedotin plus doxorubicin (A), vincristine (V), etoposide (E), prednisone (P), and cyclophosphamide (C) [brentuximab vedotin + AVEPC] was given to 300 patients, while A+bleomycin (B)+V+E+P+C [ABVE-PC] was given to 300 patients. Each treatment arm’s patients could have had up to 5 cycles of the following:
Prednisone 20 mg/m2 BID (days 1-7), cyclophosphamide 600 mg/m2 (days 1 and 2), doxorubicin 25 mg/m2 (days 1 and 2), vincristine 1.4 mg/m2 (days 1 and 8), etoposide 125 mg/m2 (days 1-3), and brentuximab vedotin 1.8 mg/kg over 30 minutes (day (days 1 and 2).
Event-free survival (EFS), which is the time from randomization to the earliest of disease progression or recurrence, second malignancy, or death from any cause, served as the primary effectiveness outcome measure. In neither arm was the median EFS attained. With a comparable hazard ratio of 0.41 (95% CI: 0.25, 0.67; p=0.0002), there were 52 occurrences (17%) in the ABVE-PC arm and 23 events (8%) in the brentuximab vedotin + AVEPC arm.
Common Adverse Events and Recommended Dosage for Pediatric Patients
In paediatric patients receiving brentuximab vedotin in combination with AVEPC, neutropenia, anaemia, thrombocytopenia, febrile neutropenia, stomatitis, and infection were the most frequent Grade 3 adverse events (5%).
For children 2 years of age and older, the suggested brentuximab vedotin dose is 1.8 mg/kg up to 180 mg in conjunction with AVEPC every 3 weeks for a maximum of 5 doses.

How CancerFax Helps
CancerFax is a specialist cancer access and patient-navigation platform. We help patients and families understand their options, organise medical records, coordinate hospital communication, and support cross-border treatment planning where appropriate.
We help collect and organise reports, scans, pathology, biomarker results, and treatment history for structured case review.
We communicate with hospitals or trial teams to assess whether a case may be suitable for further screening.
We support appointment coordination, document submission, translation, and direct communication with international departments.
For international patients, we help with practical coordination — travel planning, hospital admission guidance, and local support.
If this option is not suitable, we help explore other relevant treatments, clinical trials, or advanced care pathways.
From inquiry through to follow-up, our coordinators provide a single point of contact for the family.
CancerFax does not guarantee treatment access, eligibility, or clinical outcome. Our role is to help patients access accurate information, structured review, and appropriate specialist pathways.
