Abstract:Cancer is the leading cause of disease-related deaths among children in high-income countries. Tumor heterogeneity and the lack of mechanism of action–based therapeutic options are key challenges to overcome to improve the survival of pediatric patients with cancer. To address these challenges, we formed the European Union-Innovative Medicines Initiative 2 (EU-IMI2) funded public–private partnership “Innovative Therapies for Children with Cancer Paediatric Preclinical Proof-of-Concept Platform” (ITCC-P4), which built a large repertoire of patient-derived xenograft (PDX) models representing all major high-risk solid pediatric cancer types for in vivo drug testing. A total of 353 PDX models were established from diagnostic and relapsed pediatric cancers and molecularly characterized, together with matched germline/tumor samples. Serial PDX models were also established, spanning diagnostic/posttreatment, primary/relapse, and metastasis-derived pairs. Proof-of-concept in vivo drug screening data in neuroblastoma and rhabdomyosarcoma models identified potential predictive biomarkers for targeted therapy. Molecular data from the PDX models, accessible at https://r2platform.com/itcc-p4, allowed the selection of models for preclinical testing based on oncogenic drivers and/or potential biomarkers. Operated by a nonprofit entity, this sustainable platform aids academic and industrial researchers in developing and prioritizing innovative therapies for pediatric cancer.
Significance::The ITCC-P4 platform comprises models of diagnostic/refractory/relapsed pediatric cancers that mimic patient tumors and feature intertumoral heterogeneity, providing a resource of molecularly characterized patient-derived models for in vivo testing.
