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
- Conditions
- Carcinoma, Non-Small Cell Lung
- Interventions
- Registration Number
- NCT04611776
- Lead Sponsor
- Hoffmann-La Roche
- 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.

- Primary Outcome Measures
Name Time Method ctDNA Clearance Rate at 6 Months Randomization up to 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.
Disease-Free Survival (DFS) Randomization up to approximatly 159 months 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
- Secondary Outcome Measures
Name Time Method Percentage of Pariticipants with Adverse Events Randomization up to approximatly 159 months Percentage of participants with adverse events in the post-operative ctDNA+ participants.
Overall ctDNA Clearance Rate in the PD-L1 TC>=1% Population Randomization up to approximately 159 months Overall ctDNA clearance rate in the PD-L1 TC\>=1% (Ventana SP263) population in the post-operative ctDNA+ participants.
ctDNA Clearance Rate at 12 Months Randomization up to 12 months ctDNA clearance rate in post-operative ctDNA+ participants.
Overall ctDNA Clearance Rate Randomization up to approximately 159 months Overall ctDNA clearance rate in post-operative ctDNA+ participants.
Duration of ctDNA Clearance Up to approximatly 159 months Duration of ctDNA clearance, defined as the time from the first documented ctDNA clearance to ctDNA detection, investigator-assessed radiographic or biopsy confirmed disease recurrence, or death from any cause, whichever occurs first in post-operative ctDNA+ participants.
DFS Rate Randomization to 2 years and 3 years DFS rate at 2 years and 3 years, defined as the probability that a participant has not experienced disease recurrence, a new primary NSCLC, or death from any cause, as determined by the investigator at 2 years and 3 years, respectively in the post-operative ctDNA+ participants.
Overall survival (OS) Randomization to death from any cause (up to approximately 159 months) Overall survival (OS) after randomization, defined as the time from randomization to death from any cause in the post-operative ctDNA+ participants.
OS Rate Randomization to 2 years and 3 years OS rate at 2 years and 3 years, defined as the probability that a patient has not experienced death from any cause at 2 years and 3 years, respectively in the post-operative ctDNA+ participants.
Time to Confirmed Deterioration (TTCD) in Patient-Reported Functioning and Global Health (GHS)/Quality of Life (QoL) Up to approximately 159 months Time to confirmed deterioration (TTCD) in patient-reported functioning and global health (GHS)/quality of life (QoL), as measured by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30), and in patient-reported lung cancer symptoms for cough, dyspnea (a multi-item subscale), and chest pain, as measured through the use of the EORTC Quality-of-Life Questionnaire Lung Cancer Module (QLQ-LC13) in the post-operative ctDNA+ participants.
