A Single Arm, Phase 2 Study of Datopotamab Deruxtecan, Carboplatin, and Pembrolizumab for Treatment-naive Brain Metastases From NSCLC (Non-small Cell Lung Cancer)

46 patients around the world
Available in Brazil
This is a phase II, single-arm, multicenter trial. Patients with metastatic NSCLCs with brain metastases and without known actionable mutations will be enrolled. Patients who are eligible for the study will receive Datopotamab-deruxtecan 6 mg/kg, Carboplatin AUC 6, and Pembrolizumab 200 mg flat dose every three weeks, for four cycles, followed by maintenance of Datopotamab-deruxtecan 6 mg/kg and Pembrolizumab 200 mg until unacceptable toxicity or disease progression. Patients who present intracranial progression but do not present concurrent systemic progression may undergo stereotactic radiosurgery and continue systemic therapy on study as per investigator's decision. Patients will undergo medical evaluation and laboratory tests (hematology and blood chemistry) every 3 weeks. Abdomen/pelvis and chest CT scans, as well as brain MRIs, will be obtained at baseline, every 6 weeks during the first 24 weeks, then every 9 weeks (±7 days). Patient reported outcomes will be assessed using EORTC QLQ-C30 and QLQ-LC13 questionnaires at baseline and during treatment.
