Evidence (atezolizumab):
Two international, randomized, open-label clinical trials (OAK [NCT02008227] and POPLAR [NCT01903993]) demonstrated efficacy and safety in a total of 1,137 patients with NSCLC who previously received platinum chemotherapy.[67,68][Level of evidence A1] Compared with docetaxel, treatment with atezolizumab in the intended patient population resulted in improved OS rates of 4.2 months in the OAK study and 2.9 months in the POPLAR study.

In the OAK trial, the median OS was 13.8 months in the atezolizumab arm (95% CI, 11.8–15.7) compared with 9.6 months in the docetaxel arm (95% CI, 8.6–11.2) (HR, 0.74; 95% CI, 0.63–0.87; P = .0004).

The median OS in the POPLAR trial was 12.6 months in the atezolizumab arm (95% CI, 9.7–16.0) and 9.7 months in the docetaxel arm (95% CI, 8.6–12.0) (HR, 0.69; 95% CI, 0.52–0.92).

Although the magnitude of improvement correlated with PD-L1 immunohistochemistry expression on tumor cells and tumor-infiltrating immune cells, survival benefit with atezolizumab was seen in patients with tumors with and without PD-L1 expression.

In the POPLAR trial, the most common (≥20%) adverse reactions were in patients treated with atezolizumab and included fatigue, decreased appetite, dyspnea, cough, nausea, musculoskeletal pain, and constipation.

The most common (≥2%) grade 3 to 4 adverse events in patients treated with atezolizumab were dyspnea, pneumonia, hypoxia, hyponatremia, fatigue, anemia, musculoskeletal pain, ALT and AST increase, dysphagia, and arthralgia.

Clinically significant immune-related adverse events for patients who received atezolizumab included pneumonitis, hepatitis, colitis, and thyroid disease.
