TRIDENT-1: This phase I/II trial is trying to determine the safety and tolerability of an oral drug, repotrectinibA 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

Clinical summary

Summary

This is a dose escalation (Phase I) and expansion (Phase II) trial. In Phase I, eligible participants will receive escalating doses of Oral repotrectinib, to determine the first cycle dose-limiting toxicities, maximum tolerated dose, biologically effective dose and recommended phase 2 dose. In Phase II, participants will receive Oral repotrectinib across six distinct expansion cohorts, depending on their prior treatment and disease progression.

Conditions

This trial is treating patients with advanced or metastatic cancers that have an ALK, ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement

  11. Life expectancy ≥ 3 months.

PHASE 2 Key Inclusion Criteria

  1. Histologically or cytologically confirmed diagnosis of locally advanced, or metastatic solid tumor (including primary CNS tumors) that harbors a ROS1, or NTRK1-3 gene fusion.
  2. Subject must have a documented ROS1 or NTRK1-3 gene fusion determined by tissue-based local testing using either:

    1. a next-generation sequencing (NGS) or quantitative polymerase chain reaction (qPCR) test will be accepted to determine molecular eligibility.

      • Adequate tumor tissue needs to be sent to the Sponsor designated central diagnostic laboratory for retrospective confirmation by a central diagnostic laboratory test selected by the Sponsor.

      OR

    2. a fluorescence in situ hybridization (FISH) test AND prospective confirmation of fusion status by a central diagnostic laboratory test selected by the Sponsor PRIOR to enrollment will be accepted to determine molecular eligibility.

      • Adequate tumor tissue must be sent to the Sponsor designated central diagnostic laboratory for prospective confirmation by a central diagnostic laboratory test selected by the Sponsor PRIOR to enrollment.
  3. Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1.
  4. Age ≥12 (or age ≥ 20 as required by local regulation).
  5. Willing and able to provide written institutional review board (IRB)/institutional ethics committee-approved Informed Consent or an Assent signed by a parent or legal guardian for subjects age 12 to 17.
  6. At least 1 measurable target lesion according to RECIST (v1.1) prospectively confirmed by Blinded Independent Central Radiology Review (BICR), selected by Sponsor, PRIOR to enrollment. Subjects with CNS-only measurable disease ≥10 mm as defined by RECIST (v1.1) are eligible.
  7. Subjects with advanced solid tumors harboring ROS1, NTRK1, NTRK2, or NTRK3 rearrangement will be assigned into 6 distinct expansion (EXP) cohorts provided all inclusion and exclusion criteria are met.
