Study Overview
Brief Summary
This is a single-arm Phase Ib/II multicenter open-label study, with translational sub-study, of atezolizumab plus autologous dendritic cell vaccine as maintenance treatment in extensive-stage small cell lung cancer (ES-SCLC). It is expected that three Spanish sites will include patients in this study.
Patients will receive standard treatment with carboplatin and etoposide, plus atezolizumab for four 21-day cycles (induction phase), followed by a maintenance phase during which they will receive the dendritic cell vaccine (6 doses maximum) in combination with atezolizumab until they had unacceptable toxic effects, disease progression according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1, or no additional clinical benefit.
The two primary endpoints are the investigator-assessed toxicity and the 6 months PFS, both in the intention-to-treat population. Secondary Outcome Measures include: Duration of clinical benefit (DCB), Overall survival (OS) and Overall response rate (ORR)
The translational substudy will include:
Analysis of tumor tissue samples will consist of PD-L1 Immunohistochemistry testing, RNA expression, Work Environmental Scale (WES) analysis, and flow cytometry in pretreatment fresh tumor tissue.
The analysis will consist of T cell immunophenotyping, DC immunophenotyping, Tumoral RNA analysis by nanostring and tumoral cell-free DNA analysis by WES and cytokine analysis
