Inclusion criteria

• Cohort-specific:

Cohort 1- EGFR mutation positive NSCLC patients previously treated with appropriate targeted therapy with progressive and measurable disease per RECIST 1.1 criteria tumor.

Cohort 2- Other genetically altered NSCLC patients previously treated with appropriate targeted therapy with progressive and measurable tumor.

• Tumor tissue for PD-L1 assessment should be available unless PD-L1 assessment results are already available.

• ECOG PS 0-1 (Eastern Cooperative Oncology Group Performance Status: an attempt to quantify cancer patients' general well-being and activities of daily life. The score ranges from 0 to 5 where 0 is asymptomatic and 5 is death.)
• Patients should have recovered to ≤ grade 1 from clinically meaningful (example alopecia is not considered clinically meaningful) adverse events related to prior treatments.

• Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
• Has had targeted small molecule therapy, or palliative radiation therapy within 1 week prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.
• Has a known additional malignancy that is progressing or requires active treatment or the treating physician believes will require therapy within 1 year.
• Has symptomatic central nervous system (CNS) metastases and/or carcinomatous meningitis.
