Description

Summary

The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.

Official Title

A Phase III, Open-Label, Randomized Study of Atezolizumab and Tiragolumab Compared With Durvalumab in Patients With Locally Advanced, Unresectable Stage III Non-Small Cell Lung Cancer Who Have Not Progressed After Concurrent Platinum-Based Chemoradiation

Keywords

Non-small Cell Lung Cancer (NSCLC) Lung Neoplasms Carcinoma, Non-Small-Cell Lung Durvalumab Atezolizumab Tiragolumab Atezolizumab + Tiragolumab

Eligibility

You can join if…

Open to people ages 18 years and up

  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
  • Histologically or cytologically documented NSCLC with locally advanced, unresectable Stage III NSCLC of either squamous or non-squamous histology
  • Whole-body Positron Emission Tomography-Computed Tomography (PET-CT) scan, performed prior and within 42 days of the first dose of concurrent chemoradiotherapy (CRT)
  • At least two prior cycles of platinum-based chemotherapy concurrent with radiotherapy (cCRT), which must be completed within 1 to 42 days prior to randomization in the study
  • The radiotherapy (RT) component in the cCRT must have been at a total dose of radiation of 60 (±10 percent [%]) gray (Gy) (54 Gy to 66 Gy) administered by intensity modulated RT (preferred) or 3D-conforming technique
  • No progression during or following concurrent platinum-based CRT
  • Tumor PD-L1 expression
  • Life expectancy >/= 12 weeks
  • Adequate hematologic and end-organ function
  • Female participants must be willing to avoid pregnancy for 90 days after the final dose of tiragolumab and 5 months after the final dose of atezolizumab, or for 3 months after the final dose of durvalumab
  • Male participants must remain abstinent or use a condom during the treatment period and for 90 days after the final dose of tiragolumab
  • Male participants must not donate sperm during the treatment period and for 90 days after the final dose of tiragolumab
