Clinical Trial Summary

A phase II, single-arm, open-label study evaluating efficacy, safety and feasibility of combined chemotherapy and pembrolizumab as first line therapy and Osimertinib as second line therapy in advanced non squamous NSCLC adult patients with epidermal growth factor receptor (EGFR) exon 21 point mutation and programmed cell death receptor ligand 1 (PD-L1) positive.


Description:

Four cycles of platinum and pemetrexed in combination with pembrolizumab will be administered as first line therapy and up to 31 cycles pemetrexed and pembrolizumab maintenance therapy every 3 weeks. Osimertinib will be the sequential treatment strategy at progression.

Outcome

Type Measure Description Time frame Safety issue
Other Exploratory biomarker analysis Blood samples will be collected from patients on three occasions: before treatment, at the time of disease progression on first-line therapy, and at the time of disease progression on second-line therapy. 15ml blood samples will be collected each time for PBMC assay. Tumor samples will be collected: 10 formalin-fixed, paraffin-embedded sections. Tumor samples will be subjected to genetic testing. Blood samples will be analyzed by flow cytometry. before treatment, at the time of disease progression on first-line therapy, and at the time of disease progression on second-line therapy.
Primary progression free survival 1 (PFS1) the time length from enrollment to any of the following events: disease progression with first line therapy or death from any cause. Disease progression will be assessed according to RECIST 1.1 up to 8 weeks
Secondary progression free survival 2 (PFS2) the time length from enrollment to any of the following events: disease progression with Osimertinib or death from any cause. Disease progression will be assessed according to RECIST 1.1 up to 8weeks
Secondary Incidence of adverse events graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Evaluate adverse events of any cause, treatment-related adverse events, immune-mediated adverse events according to NCI-CTCAE V5.0 up to 8 weeks
Secondary objective response rate (ORR) Proportion of patients with Complete and Partial Responses to first-line therapy. up to 8 weeks
Secondary Life quality score Evaluate life quality score according to Karnofsky performance status (KPS). On a scale of 10, higher scores indicate better health. A score of 0 is defined as death, on a 100-point scale, indicating normal physical fitness with no obvious symptoms and signs. up to 8 weeks
