Brief Summary:

The purpose of the study is to compare the overall response rate (ORR) in non-small cell lung cancer (NSCLC) participants treated with daratumumab in combination with atezolizumab versus atezolizumab alone.

Condition or disease	Intervention/treatment	Phase
Carcinoma, Non-Small-Cell Lung	Drug: Atezolizumab; Drug: Daratumumab	Phase 1; Phase 2

Detailed Description:

This randomized (study medication assigned to participants by chance), multicenter study will provide study treatment (atezolizumab alone or atezolizumab+daratumumab) to participants with previously treated advanced or metastatic NSCLC to assess the anti-tumor activity and safety. Participants who receive atezolizumab treatment with confirmed disease progression based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 will be eligible to crossover to treatment (atezolizumab + daratumumab) if they meet crossover eligibility criteria. It is expected that 100 participants will enroll in the study including 6 participants in the safety run in phase. Data Monitoring Committee (DMC) will review ongoing data, and may formulate recommendations on study conduct, including expansion of enrollment of some PD-L1 subgroups, resulting in greater than 96 participants. The participants in the safety run in phase will be administered the combination of daratumumab and atezolizumab to determine the safety and tolerability that will be evaluated by the Safety Evaluation Team (SET) for dose limiting toxicity before the random assignment of participants in a 1:1 ratio in 2 treatment arms. The study consists of 3 phases: Screening Phase (up to 28 days), Treatment Phase and Post-Treatment Follow-up Phase which will continue until death, lost to follow-up, withdrawal of consent, or the End of the Study [the study end is approximately 6 to 12 months after that last participant is enrolled]. Participants will undergo tumor assessments (RECIST 1.1), immunogenicity, pharmacokinetics, biomarkers and safety evaluations (adverse events, laboratory tests, electrocardiogram [ECGs], vital sign measurements, physical examinations, Eastern Cooperative Oncology Group [ECOG] performance status score) over the time.
