A Phase III Study Comparing Taletrectinib With Standard Therapy in ROS1 Positive Locally Advanced or Metastatic Non-small Cell Lung Cancer Patients

Recruitment & Eligibility

Status: Not yet recruiting

Sex: All

Target Recruitment: Not specified

Inclusion Criteria

Inclusion Criteria: 1. Histologically or cytologically confirmed diagnosis of locally advanced or recurrent (Stage IIIB not amenable for multimodality treatment) or metastatic (Stage IV) NSCLC. 2. Have documentation of ROS1 rearrangement by a positive result 3. Have at least 1 measurable (i.e., target) lesion by Investigator assessment per RECIST v1.1. 4. Prior brain or leptomeningeal metastases allowed if asymptomatic and diagnosed incidentally at study baseline. If participants have neurological symptoms or signs due to CNS metastasis, participants need to complete local therapy (surgery and/or radiation) at least 7 days before enrollment and be clinically stable without requiring for an increasing dose of corticosteroids or use of anticonvulsants to control symptoms. 5. Age =18 years (or =20 years as required by local regulations). 6. Eastern Cooperative Oncology Group (ECOG) performance status zero (0) to 1. 7. Minimum life expectancy of 3 months or more. 8. Adequate organ function meeting the following criteria: 1. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT): =3.0 × upper limit of normal (ULN) (or =5.0 × ULN, for participants with concurrent liver metastases). 2. Serum total bilirubin: =1.5 × ULN (=3.0 × ULN for participants with Gilbert syndrome). 3. Absolute neutrophil count: =1500/µL. 4. Platelet count: =75,000/µL. 5. Hemoglobin: =9.0 g/dL. 6. Estimated creatinine clearance (CLcr) =45 mL/min as calculated using the method standard for the institution (e.g., Cockcroft-Gault Equation, i.e., CCr={((140-age)×weight)/(72×SCr)}×0.85 (if female) (Cockcroft and Gault 1976). 9. All toxicities from prior anticancer therapy have resolved to = Grade 1 according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v5.0), or have resolved to previous baseline, at the time of randomization. 10. The participant is willing and capable of giving written informed consent. Exclusion Criteria: 1. Previously received an investigational antineoplastic agent for NSCLC. 2. Previously received any prior TKI, including ROS1-targeted TKIs. 3. Received immune checkpoint inhibitors for locally advanced or metastatic disease. 4. Previously received more than 1 regimen of systemic anticancer therapy for locally advanced or metastatic disease. 5. Had major surgery within 28 days prior to randomization. Minor surgical procedures, such as catheter placement or minimally invasive biopsy, are allowed. 6. Have symptomatic CNS metastases (parenchymal or leptomeningeal) at Screening or asymptomatic disease requiring an increasing dose of corticosteroids to control symptoms within 7 days prior to randomization. Participants with no prior history of signs or symptoms of CNS metastases but who receive prophylactic steroids or anticonvulsants are allowed. 7. Have current spinal cord compression (symptomatic or asymptomatic and detected by radiographic imaging). Participants with leptomeningeal disease and without cord compression are allowed. 8. Uncontrolled pleural, abdominal, or pericardial effusion within 28 days prior to randomization, which is associated with malignant effusion requiring recurrent drainage procedures (once monthly or more frequently). 9. Have been diagnosed with another primary malignancy other than NSCLC except for adequately treated nonmelanoma skin cancer or cervical cancer in situ; definitively treated nonmetastatic prostate cancer; or participants with another primary malignancy who are definitively relapse-free with at least 3 years elapsed since the diagnosis of the other primary malignancy. 10. Have clinically significant cardiovascular diseases within 6 months prior to randomization: myocardial infarction, severe/unstable angina, coronary/peripheral endovascular treatment, heart failure, cerebrovascular disorder including transient ischemic attack, pulmonary embolism, deep venous thrombosis and or other clinically significant thrombosis. 11. Have a known history of uncontrolled hypertension. Participants with hypertension should be under treatment on study entry to control blood pressure. 12. Have ongoing cardiac dysrhythmias of =CTCAE Grade 2, uncontrolled atrial fibrillation of any grade, or QT interval corrected for heart rate by Fredericia's formula (QTcF) >470 milliseconds (female) or >450 milliseconds (male), or symptomatic bradycardia <45 bpm within 6 months before enrollment; participants treated with medications known to be associated with the development of TdP . 13. Have active and clinically significant bacterial, fungal, or viral infection including but not limited to hepatitis B virus (HBV), hepatitis C virus (HCV), known HIV or AIDS-related illness 14. Currently have or have a history of interstitial lung disease (ILD), drug-related pneumonitis, or radiation pneumonitis that required steroid treatment. 15. Be pregnant or breastfeeding
