Access Program for Unapproved and Off-Label Drug Use in Pediatric BRAF V600E-Mutated Brain Tumors in Japan.

Abstract

Programs allowing access to investigational drugs and off-label drug use for serious diseases have often been applied to pediatric cancers. A clinical study conducted under the Japanese "Patient-Proposed Healthcare Services" evaluated the efficacy and safety of dabrafenib plus trametinib in children with BRAF V600 mutant glioma (jRCTs071210071). This study successfully provided unapproved and off-label medications to four enrolled patients, two with low-grade glioma and two with high-grade glioma (median age: 10.5 years), until regulatory approval. The timeframe and data collection from such access programs need to be optimized for pediatric patients in accordance with the healthcare system of each nation.
