Study Stopped
The positive results from IMpower010 demonstrated benefit by adding atezolizumab as adjuvant therapy in early stage NSCLC. These results raised ethical concerns of enrolling pts to best supportive care over checkpoint inhibition in this setting.
A Study Evaluating the Efficacy and Safety of Adjuvant Platinum-Doublet Chemotherapy, With or Without Atezolizumab, in Patients Who Are ctDNA Positive After Complete Surgical Resection of Stage IB to Select IIIB Non-Small Cell Lung Cancer

Brief Summary
This is a Phase II, multicenter, double-blind, randomized study designed to evaluate the efficacy and safety of adjuvant treatment with atezolizumab in combination with platinum-doublet chemotherapy followed by atezolizumab compared with adjuvant placebo in combination with platinum-doublet chemotherapy followed by placebo in patients with Stage IB to IIIB (T3N2) NSCLC following surgical resection who are positive for ctDNA.

Outcome Measures
Primary Outcomes (2)
ctDNA Clearance Rate at 6 Months
ctDNA clearance rate at 6 months after randomization, defined as the proportion of participants with undetectable ctDNA at 6 months in the post-operative ctDNA+ participants.
Randomization up to 6 months
Disease-Free Survival (DFS)
Disease-free survival (DFS), as assessed by the investigator, and defined as the time from randomization to the date of occurrence of any of the following, whichever occurs first: First documented local or distant recurrence of non-small cell lung cancer (NSCLC) after an integrated assessment of radiographic data, biopsy sample results (if available), and clinical status; Occurrence of new primary NSCLC (non-small cell lung cancer); Death from any cause in the post-operative ctDNA+ participants
Randomization up to approximatly 159 months
Secondary Outcomes (9)
ctDNA Clearance Rate at 12 Months
Randomization up to 12 months
Overall ctDNA Clearance Rate
Randomization up to approximately 159 months
Duration of ctDNA Clearance
Up to approximatly 159 months
Overall survival (OS)
Randomization to death from any cause (up to approximately 159 months)
DFS Rate
Randomization to 2 years and 3 years
- +4 more secondary outcomes
