Palliative RadIotherapy of Multiple Metastatic Sites Before First Line of Systemic Therapy with Immune Checkpoint Inhibitors and Chemotherapy in Metastatic Non-Small-Cell Lung Cancer (PRIMM Study)
The study is designed as a non-randomized Phase 2 clinical intervention study. The study will include patients with disseminated Non-Small Cell Lung Carcinoma (NSCLC) which are eligible for first line of systemic treatment with immune checkpoint inhibitors and platinum-based chemotherapy (PDL1 less than 50%). Patients will receive palliative radiotherapy to multiple sites (2 to 5 sites) prior to systemic treatment. Results of treatment will be compared to historical cohort of patients treated only with systemic therapy.
• Signed consent to the study before the start of the procedures related to the protocol
• Age ≥ 18 years at time of study entry
• ECOG performance status 0-2
• Histologically or cytologically confirmed non-small cell lung cancer, with expression of PD-L1 of less than 50%
• Stage IV metastatic Non-Small Cell Cancer confirmed by CT scan (of brain, chest and abdomen) or PET CT
• Patients must be eligible for first line of systemic treatment with standard of care checkpoint inhibitor immune therapy and chemotherapy - according to the recommendations
• inclusion of patients treated for few brain metastases (with surgery or ablative radiosurgery) is permitted (if the disease in the central nervous system is under control)
• Prior surgery (diagnostic and therapeutic) and irradiation (for example: stereotactic irradiation of brain metastases) is permitted, provided that patients have fully recovered from the procedure at least 2 weeks before inclusion in the study
• Patients treated with surgery or radiation and chemotherapy for limited non-small cell carcinoma in the past is permitted
