MedicalResearch.com Interview with: Douglas S. Hawkins, M.D. Hematology/Oncology Division Chief and Professor Pediatrics at Seattle Children's Hospital University of Washington School of Medicine MedicalResearch.com: What is the background for this study? Response: TRK fusion cancer is caused by a rare genomic alteration called a neurotrophic receptor tyrosine kinase (NTRK) gene fusion. Larotrectinib is a central nervous system (CNS) active, oral and highly selective TRK inhibitor used for the treatment of adult and pediatric patients with solid tumors that have a rare genomic alteration called an NTRK gene fusion. Larotrectinib was approved at the end of 2018 in the U.S. under the brand name VITRAKVI^®, with European and worldwide regulatory submissions underway. At ASCO 2019, we will be presenting results from a new analysis specifically looking at the efficacy and safety of larotrectinib in pediatric patients (n=34) included in the expanded dataset from both adults and children across 24 tumor types, which was presented first at the European Society for Medical Oncology (ESMO) 2019 Annual Meeting.  (more…)
