Trial Outcomes & Findings for Immunotherapy With or Without SBRT in Patients With Stage IV Non-small Cell Lung Cancer (NCT NCT03867175)
NCT ID: NCT03867175
Last Updated: 2025-06-13
Results Overview
Will be determined using the product-limit method of Kaplan and Meier. Will compare unadjusted median PFS between the 2 arms using a log-rank test. Will also use a proportional hazards model to compare progression-free survival between the two groups, adjusting for key covariates such as age, performance (Eastern Cooperative Oncology Group) status, response to initial systemic therapy versus (vs) stable disease, the presence or absence of brain metastases, PD-L1 \[programmed death-ligand \] expression (\< 1% vs \> 50%), tumor histology (adenocarcinoma vs non-adenocarcinoma), and number of disease sites treated (1-3 sites vs 4-6 sites). Progression is defined using RECIST v1.1 is relative Increase: A 20% increase in the sum of the longest diameters of target lesions (from baseline or nadir) is a criterion for PD.

Timeframe: Up to 5 yearsAll safety measures, including acute and late toxicity, will be reported using descriptive statistics (mean, median, standard deviation, proportions, and 95% confidence intervals). This will include calculating frequency/risk of adverse events by treatment site. Potential toxicities reported would include pneumonitis, esophagitis, chest wall pain, dermatologic toxicity, renal dysfunction, gastrointestinal toxicity including nausea, vomiting, and diarrhea, hepatotoxicity, and abdominal pain. These toxicities would be assessed according to site of irradiation by the treating physician and graded as per Common Terminology Criteria for Adverse Events 5.
