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 CYP3A induction. Phase 2 will determine the confirmed Overall Response Rate (ORR) as assessed by Blinded Independent Central Review (BICR) of repotrectinib in each subject population expansion cohort of advanced solid tumors that harbor a ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement. The secondary objective will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS) and clinical benefit rate (CBR) of repotrectinib in each expansion cohort of advanced solid tumors that harbor a ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement.

Detailed description

In Phase 2, study subjects will be enrolled into 6 distinct expansion (EXP) cohorts: * EXP-1: ROS1 TKI-naïve ROS1+ NSCLC. Up to one prior line of chemotherapy OR immunotherapy is allowed * EXP-2: 1 Prior ROS1 TKI AND 1 Platinum-based Chemotherapy ROS1+ NSCLC. Disease progression, or intolerant to one prior line of a ROS1 TKI. Must have received one prior line of platinum based chemotherapy OR one prior line of platinum based chemotherapy in combination with immunotherapy before or after a ROS1 TKI * EXP-3: 2 Prior ROS1 TKIs AND NO Chemotherapy ROS1+ NSCLC. Disease progression, or intolerant to 2 prior lines of a ROS1 TKI treatment. No prior lines of chemotherapy or immunotherapy are allowed. * EXP-4: 1 Prior ROS1 TKI and NO Chemotherapy or Immunotherapy. Disease progression or intolerant to one prior line of a ROS1 TKI. No prior lines of chemotherapy or immunotherapy are allowed. * EXP-5: TRK TKI-naïve NTRK+ solid tumors. Any number of prior lines of chemo or immunotherapy is allowed. * EXP-6: TRK TKI-pretreated NTRK+ solid tumors. Disease progression, or intolerant to 1 or 2 prior TRK TKIs. Any number of prior lines of chemo- or immunotherapy are allowed.
