• The RACE for Children Act mandates testing of new oncology drugs in children if their molecular targets are relevant to pediatric cancers, impacting drug development.
• Patient-derived xenograft (PDX) models, which preserve the heterogeneity of original tumors, are crucial for preclinical testing of drugs for rare pediatric cancers.
• The ITCC-P4 consortium, including Charles River Laboratories, supports drug developers with preclinical testing, offering access to over 200 characterized PDX models.
• This initiative aims to accelerate the development of effective treatments for pediatric cancers, ultimately increasing treatment options for young patients.
