Description

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. 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 an ALK, 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 an ALK, ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement.

Official Title

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)

Details

In Phase 2, study subjects will be enrolled into 6 distinct expansion (EXP) cohorts:

  • EXP-1: ROS1+ NSCLC. No prior ROS1TKI allowed. Any prior lines of chemotherapy or immunotherapy are allowed.
  • EXP-2: ROS1+ NSCLC. Disease progression on one prior ROS1 TKI only. Any prior lines of chemotherapy or immunotherapy are allowed.
  • EXP-3: ROS1+ NSCLC. Disease progression on two prior ROS1 TKIs only. Any prior lines of chemotherapy or immunotherapy allowed.
  • EXP-4: ROS1+ or ALK+ non-NSCLC advanced solid tumors. No prior ROS1 or ALK TKIs allowed. Any prior lines of chemotherapy or immunotherapy allowed.

NTRK Advanced Solid Tumors:

  • EXP-5: NTRK+ advanced solid tumors. No prior TRK TKI is allowed.
  • EXP-6: NTRK+ advanced solid tumors. No more than 2 prior TRK TKIs are allowed. Prior lines of chemotherapy or immunotherapy allowed.

Eligibility

For people ages 18 years and up

Key Inclusion Criteria:

  1. Histologically or cytologically confirmed diagnosis of locally advanced, or metastatic solid tumor (including primary CNS tumors) (Stage IV, American Joint Committee on Cancer v.7) that harbors an ALK, ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement by protocol specified tests.
  2. ECOG PS 0-1.
  3. Age ≥18 (or age ≥ 20 of age as required by local regulation). In Phase 2, Age ≥12 is allowed.
  4. Capability to swallow capsules intact (without chewing, crushing, or opening).
  5. At least 1 measurable target lesion according to RECIST version 1.1. CNS-only measurable disease as defined by RECIST version 1.1 is allowed.
  6. Prior cytotoxic chemotherapy is allowed.
  7. Prior immunotherapy is allowed.
  8. Resolution of all acute toxic effects (excluding alopecia) of any prior anti-cancer therapy to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.03 Grade less than or equal to 1.
  9. Patients with asymptomatic CNS metastases (treated or untreated) and/or asymptomatic leptomeningeal carcinomatosis are eligible to enroll if they satisfy the protocol specified criteria.
  10. . Life expectancy ≥ 3 months.

Key Exclusion Criteria:

  1. Concurrent participation in another therapeutic clinical trial.
  2. Symptomatic brain metastases or leptomeningeal involvement.
  3. History of previous cancer, except for squamous cell or basal-cell carcinoma of the skin, or any in situ carcinoma that has been completely resected, requiring therapy within the previous 2 years.
  4. Major surgery within 4 weeks of start of treatment
  5. Clinically significant cardiovascular disease (either active or within 6 months prior to enrollment): myocardial infarction, unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure (New York Heart Association Classification Class ≥ II), cerebrovascular accident or transient ischemic attack, symptomatic bradycardia, requirement for anti-arrhythmic medication. Ongoing cardiac dysrhythmias of NCI CTCAE grade ≥2
  6. Any of the following cardiac criteria:
  7. Mean resting corrected QT interval (ECG interval measured from the onset of the QRS complex to the end of the T wave) for heart rate (QTcF) > 470 msec obtained from 3 ECGs, using the screening clinic ECG machine-derived QTc value
  8. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g., complete left bundle branch block, third degree heart block, second degree heart block, PR interval > 250 msec)
  9. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or any concomitant medication known to prolong the QT interval.
  10. Known active infections (bacterial, fungal, viral including HIV positivity).
  11. Gastrointestinal disease (e.g., Crohn's disease, ulcerative colitis, or short gut syndrome) or other malabsorption syndromes that would impact drug absorption.
  12. Peripheral neuropathy of CTCAE ≥grade 2.
  13. . History of extensive, disseminated, bilateral, or presence of CTCAE grade 3 or 4 interstitial fibrosis or interstitial lung disease including a history of pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, interstitial lung disease, obliterative bronchiolitis, and pulmonary fibrosis. Subjects with history of prior radiation pneumonitis are not excluded.
