RXDX-101-03 – A Phase 1/1b, Open-Label, Dose-Escalation and Expansion Study of Entrectinib (RXDX-101) in Children and Adolescents with Recurrent or Refractory Solid Tumors and Primary CNS Tumors, with or without TRK, ROS1, or ALK Fusions (Igny

This is a 5-part, open-label, Phase 1/1b multicenter, dose escalation study in pediatric patients with relapsed refractory solid tumors; 2) primary CNS tumors; 3) neuroblastoma; 4) non-neuroblastoma, extracranial solid tumors with NTRK1/2/3, ROS1 or ALK gene rearrangements; and 5) patients who are otherwise eligible but unable to swallow capsules. The study is designed to explore the safety, maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D), pharmacokinetics, and antitumor activity of entrectinib.
