Open-label Phase II Efficacy Study of Repotrectinib in Frail (PS ≥2) and/or Elderly Patients With ROS1-rearranged Advanced NSCLC
Summary: ROS1 rearrangements are rare, accounting for only 1-2% of NSCLC cases, but have been associated with response to ROS1 inhibitors, such as crizotinib and entrectinib. However, many patients develop resistance to the tyrosine-kinase inhibitors (TKIs), creating a need for new treatments. Repotrectinib is a new-generation TKI designed against ROS1 or NTRK rearranged malignancies (Drilon 2018). Early p...
A Phase 1/2, Open-Label, Safety, Tolerability, Pharmacokinetics, and Anti-Tumor Activity Study of Repotrectinib in Pediatric and Young Adult Subjects With Advanced or Metastatic Malignancies Harboring ALK, ROS1, NTRK1-3 Alterations
Summary: Phase 1 will evaluate the safety and tolerability at different dose levels of repotrectinib in pediatric and young adult subjects with advanced or metastatic malignancies harboring anaplastic lymphoma kinase (ALK), receptor tyrosine kinase encoded by the gene ROS1 (ROS1), or neurotrophic receptor kinase genes encoding TRK kinase family (NTRK1-3) alterations to estimate the Maximum Tolerated Dose (...
Phase 1/2 Study of TPX-0005 (Repotrectinib) in Combination With Chemotherapy in Pediatric and Young Adult Subjects With Advanced or Metastatic Solid Tumors and Primary Central Nervous System Tumors
Summary: This study will test the safety of the study drug, repotrectinib, in combination with chemotherapy (irinotecan and temozolomide) in children and young adults who have advanced or metastatic solid tumors. We researchers will try to find the highest dose of the study drug that causes few or mild side effects in study participants. When the researchers find this dose, we will evaluate it in a differe...
A Phase II Study Assessing Safety and Efficacy of REPotrectinib in ROS1-positive Non-small Cell Lung Cancer Patients With Active Brain mEtastasis (REPOSE Study)
Summary: REPOSE is a phase II clinical trial exploring the safety and efficacy of repotrectinib in patients with non-small cell lung cancer (NSCLC) characterized by the presence of brain metastasis (BM) and whose tumors have mutated ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) gene.
A Phase 1/2, Open-Label, Multi-Center, First-in-Human Study of the Safety, Tolerability, Pharmacokinetics, and Anti-Tumor Activity of TPX-0005 in Patients With Advanced Solid Tumors Harboring ALK, ROS1, or NTRK1-3 Rearrangements (TRIDENT-1)
Summary: Phase 1 dose escalation will determine the first cycle dose-limiting toxicities (DLTs), the maximum tolerated dose (MTD), the biologically effective dose and recommended Phase 2 dose (RP2D) of repotrectinib given to adult subjects with advanced solid malignancies harboring an ALK, ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement. Midazolam DDI substudy will examine effect of of repotrectinib on CYP...
Phase I Clinical Study to Assess Safety and Efficacy of Repotrectinib Combined With Osimertinib in Patients With Advanced, Metastatic EGFR Mutant NSCLC (TOTEM).
Summary: This is a Phase I study of repotrectinib in combination with osimertinib in patients with advanced or metastatic EGFR mutant non small cell lung cancer (NSCLC). The study will be conducted in 2 parts, Part Ia and Part Ib, and its purpose will be to find the incidence of dose-limiting toxicities (DLTs) as defined by the primary safety and tolerability endpoint. The Phase Ia study will also determin...
