Clinical Trial Summary

This is a multicenter, double-blind, placebo-controlled, randomized, phase II study to investigate the efficacy and safety of Atezolizumab with or without Tiragolumab as consolidation therapy in participants with limited stage small cell lung cancer who have not progressed during/after chemoradiotherapy.

Description:

Participants can receive concurrent or sequential chemoradiotherapy (CRT) as per local standard of care, but they must be randomized within 6 weeks from completion of chemoradiotherapy. Participants should receive 4 cycles of chemotherapy and radiotherapy dose of 56-64 Gy (once daily) before randomization, and those participants who have not progressed during/after CRT will be stratified by response to CRT, radiotherapy timing, and be randomized in a 1:1 ratio to Atezolizumab+Tiragolumab arm or Atezolizumab+placebo arm.

There are two components to the EQ-5D-5L: a five-item health state profile that assesses mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, as well as a visual analogue scale (VAS) that measures health state. Published weighting systems allow for creation of a single composite score of the patient's health status.
