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.

Official Title

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


Solid Tumors CNS Tumors Neuroblastoma TRK Tyrosine kinase NTRK NTRK1 NTRK2 NTRK3 ROS1 ALK Pediatric Relapsed Refractory Solid Tumor Metastatic Cancer Gene rearrangement Infantile fibrosarcoma Secretory breast cancer Congenital mesoblastic nephroma Pontine glioma Brain tumors Sarcoma Ewing sarcoma Glial tumors Salivary Gland Cancer (MASC) Papillary thyroid cancer Medulloblastoma Wilms tumor (anaplastic) Neoplasms Central Nervous System Neoplasms

  10. Histologic/molecular diagnosis of malignancy at diagnosis or the time of relapse
  11. Archival tumor tissue from diagnosis or, preferably, at relapse
  12. Age: Male or female age ≥ 2 years and < 22 years unless enrolled in Part E
  13. Performance status: Lansky or Karnofsky score ≥ 60% and minimum life expectancy of at least 4 weeks
  14. Patient's cancer must have relapsed after or failed to respond to frontline curative therapy or there must not be other potentially curative treatment options available
  15. . Adequate organ and neurologic function
  16. . Females of child bearing potential must have a negative serum pregnancy test within 14 days prior to entrectinib dosing

You CAN'T join if...

  1. Receiving other experimental therapy
  2. Known congenital long QT syndrome
  3. Known active infections
  4. Receiving Enzyme Inducing Antiepileptic Drugs (EIAEDs) within 14 days of first dose.
  5. Incomplete recovery from acute effects of any surgery prior to treatment.
  6. Active gastrointestinal disease or other malabsorption syndromes that would impact drug absorption.
  7. Other severe acute or chronic medical or psychiatric condition or lab abnormality that may increase the risk associated with study participation, drug administration or may interfere with the interpretation of study results.
