Phase II Randomized Trial of Carboplatin+Pemetrexed+Bevacizumab+/- Atezolizumab in Stage IV NSCLC
Trial Parameters
Brief Summary
While cigarette smoking remains the primary cause of most lung cancer cases, lung carcinoma in never smokers account for nearly 20 percent of cases. Never smokers with lung cancer typically present with different molecular profiles from that of smokers, which results in prognostic and therapeutic implications. Molecular changes in NSCLC that have therapeutic significance include mutations in the epidermal growth factor receptor (EGFR) and rearrangements in the anaplastic lymphoma kinase (ALK) gene. These driver mutations typically are present in lung tumors found in never or light smokers. The addition of bevacizumab to carboplatin and paclitaxel in first-line treatment of non-squamous NSCLC showed improved survival compared to carboplatin and paclitaxel alone, 12.3 vs. 10.3 months respectively. Results from the POINTBREAK trial demonstrated that carboplatin + pemetrexed + bevacizumab is an alternative option to carboplatin + paclitaxel + bevacizumab, with comparable survival but less toxicity. In recent years, immunotherapy has emerged as a form of treatment that can lead to robust responses in a subset of patients. The PD-1 inhibitor nivolumab and the PD-L1 inhibitor atezolizumab have shown prolonged survival in comparison to docetaxel in patients who previously progressed with chemotherapy, irrespective of PD-L1 expression. Thus, this study combines immunotherapeutic agent atezolozumab with an ant-angiogenic agent, bevacizumab, and double platinum therapy (carboplatin and pemetrexed).
Eligibility Criteria
Inclusion Criteria: * Must have histologically or cytologically confirmed stage IV non-squamous non-small cell lung cancer * Must have either tumors that harbor an EGFR mutation in exon 19 or exon 21, or must be never smoker wild-types. Never smoker wild-types are defined as patients with tumors without an ALK or ROS1 rearrangement, and are not harboring any EGFR mutation (this includes exons 19 or 21, exon 20, and any other rare EGFR mutations). Never smoker wild-type patients must have smoked less than 100 cigarettes in a lifetime. Patients with an EGFR mutation in exon 19 or 21 may be included irrespective of their smoking history. If a patient whose tumor originally had an exon 19 or 21 mutation develops a secondary activating or sensitizing mutation in exon 18-21 as a result of resistance to EGFR TKI therapy, then that patient is eligible. If tissue-based testing for EGFR mutation status is not available, blood-based EGFR testing that confirms presence of a mutation in exon 19 or
