Phase 3 Study Comparing Targeted High-Dose Radiation and Usual Chemotherapy with Immunotherapy or Targeted Therapy in Inoperable Locally Advanced Non-Small Cell Lung Cancer

What this Trial Is About

Researchers are evaluating whether adding stereotactic body radiation therapy SBRT to the usual treatment improves outcomes for patients with locally advanced, inoperable non-small cell lung cancer NSCLC that has spread to nearby tissues or lymph nodes. This phase III trial compares the effect of SBRT combined with conventional image guided radiation therapy IGRT, chemotherapy, and immunotherapy or targeted therapy against the usual treatment alone. The study aims to assess overall survival, progression-free survival, tumor response, lung function, quality of life, and treatment-related side effects. Participants are randomly assigned to one of two groups. In the first group, patients receive conventional IGRT and chemotherapy with drugs such as paclitaxel, carboplatin, pemetrexed, cisplatin, or etoposide during radiation, followed by immunotherapy with durvalumab or targeted therapy with osimertinib. The second group receives SBRT combined with conventional IGRT and similar chemotherapy, followed by the same immunotherapy or targeted therapy options. Both groups undergo CT andor PETCT scans during follow-up. Chemotherapy schedules vary by drug, including weekly or every 21-day dosing during radiotherapy, with consolidation treatments lasting up to one year. Throughout the study, participants undergo assessments including lung function tests FEV1 and DLCO, quality of life questionnaires, imaging scans, and monitoring for side effects using standard criteria. Follow-up visits occur every three months for the first year, every six months during years two and three, and annually thereafter, continuing for the duration of the study. Biospecimens and advanced imaging data are collected for exploratory analyses, including development of machine learning tools for radiation planning. Overall survival and progression-free survival are the primary outcomes measured up to eight years after randomization.
