Researchers test if electronic health records can mimic Gold-Standard cancer studies
NCT ID NCT07485166
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether information from electronic health records can be used to recreate the results of two earlier clinical trials (CheckMate 017 and 057) for advanced lung cancer. Researchers will compare survival outcomes in patients who started either nivolumab or docetaxel, using data from over 800 patients. The goal is not to find a new treatment, but to see if real-world data can reliably answer clinical questions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show that real-world data can reliably replace some traditional trials, speeding up research and lowering costs.
- What could go wrong
- This is an observational study, not a new treatment test. Results may not match the original trials due to data quality or hidden biases.

Study Period: ENCORE database 1 (EDB1): Patient identification period: 01/01/2011-04/30/2024 with follow-up information through data cut-off date on 04/30/2024 ENCORE database 2 (EDB2): Follow-up information through February 2023 (there is no specific time period restrictions for patient eligibility) ENCORE database 4 (EDB4): Patient identification period: 10/01/2018-09/30/2023 with follow-up information through data cut-off date on 09/30/2023. Inclusion Criteria: * Age ≥18 years at treatment initiation * Line-of-therapy setting is "advanced" (EDB1), "metastatic" (EDB2), or evidence of metastatic disease at treatment initiation (EDB4) * Subjects with NSCLC who present with advanced/metastatic (Stage IIIB/ Stage IV) disease and received treatment with nivolumab or docetaxel is 2L for advanced/metastatic diseases * ECOG 0 or 1 in the 90 days before/on treatment initiation Exclusion Criteria: * Patients without documentation of disease progression between initiation of 1L platinum doublet-based chemotherapy and initiation of nivolumab or docetaxel * Patients with documentation of docetaxel or nivolumab use before treatment initiation * Patients with documentation of immunotherapy use before treatment initiation * Patients with any prior non-lung malignancy diagnosis (except non-melanoma skin cancers and specified in situ cancers: bladder, gastric, colon, cervical/dysplasia, endometrial, melanoma, or breast) * Patients with documented autoimmune diseases within 2 years before/on treatment initiation * Patients with documented interstitial lung disease before/on treatment initiation * Patients with documented CNS metastases before/on treatment initiation * Patients with any other anti-cancer therapy during the treatment assessment window
