A Single-Arm, Open-Label, Multicenter Phase 2 Study to Evaluate the Efficacy and Safety of Taletrectinib in Patients With Advanced or Metastatic ROS1 Positive NSCLC and Other Solid Tumors

NCT #

Condition(s)

Lung Cancer (NSCLC)

Molecular Target(s)

ROS1

Drug Classification(s)

Molecular Targeted Therapy

Agents(s)

Prior treatment with an mTOR inhibitor, including nab-sirolimus.Severe (Grade ≥3) ongoing infection requiring parenteral or oral anti-infective treatment, either ongoing or completed ≤7 days prior to enrollment.Patients with primary brain tumors or PEComa.Patients who have any severe and/or uncontrolled medical or psychiatric conditions or other conditions that could affect their participation including:Patients with meningeal carcinomatosis, leptomeningeal carcinomatosis, spinal cord compression, untreated brain metastases or symptomatic or unstable brain metastases. Note: Patients with stable brain metastases (defined as asymptomatic or no requirement for high-dose [defined as dexamethasone 10 mg daily or higher] or increasing dose of systemic corticosteroids) and without imminent need of radiation therapy are eligible. If applicable, patients must have completed brain radiation therapy and recovered adequately from any associated toxicity and/or complications prior to eligibility assessment. For patients who have received prior radiation therapy, post-treatment MRI scan should show no increase in brain lesion size/volume.Unstable angina pectoris, symptomatic congestive heart failure (New York Heart Association, NYHA class III or IV), myocardial infarction ≤6 months prior to first study treatment, serious uncontrolled cardiac arrhythmia or any other clinically significant cardiac disease.Pre-existing severely impaired lung function. If a patient has a pre-existing pulmonary condition, eligible patients should have a spirometry and diffusing capacity for carbon monoxide (DLCO) that is >50% of the normal predicted value and/or O2 saturation that is >88% at rest on room air (Note: spirometry and pulmonary function tests [PFTs] not required to be performed unless clinically indicated).Nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with the study therapy.A history of malignancies other than the one under treatment unless the patient is disease-free for more than 5 years from diagnosis. Note, controlled non-melanoma skin cancers, carcinoma in situ of the cervix, resected incidental prostate cancer, certain low grade hematologic malignancies (eg CLL, follicular lymphoma, etc), or other adequately treated carcinoma-in-situ may be eligible, after discussion with the medical monitor.Uncontrolled hypertension (systolic blood pressure ≥160 mm-Hg and/or diastolic blood pressure ≥100 mm Hg).Patients with history of interstitial lung disease and/or pneumonitis, or pulmonary hypertension.Individuals with known human immunodeficiency virus (HIV) infection are excluded from this study as combination antiretroviral therapy could potentially result in significant pharmacokinetic interactions. In addition, these individuals are at increased risk of serious infections due to the immunosuppressive effects of mTOR inhibition.Active Hepatitis B or Hepatitis C, with detectable viral load.Regarding concomitant medications with significant CYP3A4 and P-gp interactions, discontinuation of strong inhibitors (eg, ketoconazole, itraconazole, voriconazole, erythromycin, clarithromycin, telithromycin, and others), strong inducers (eg, rifampin, rifabutin), and known CYP3A4 substrates with a narrow therapeutic window (eg, fentanyl, alfentanil, astemizole, cisapride, dihydroergotamine, pimozide, quinidine, or terfenadine) is required at least 5 half lives prior to receiving the first dose of nab-sirolimus, whichever is longer.
