The combination of chemotherapy plus immunotherapy has become standard of care for patients who have PD-L1 expression <50%, irrespective of histology, according to the results of several phase III clinical trials.
For patients with PD-L1 expression ≥50%, chemotherapy plus immunotherapy can also be considered, particularly for patients who have significant disease burden. However, these patients can also consider pembrolizumab (Keytruda) monotherapy based on data from the phase III KEYNOTE-024 trial, which demonstrated a significant improvement in progression-free survival versus platinum doublet chemotherapy alone. Currently, there is no head-to-head comparison of pembrolizumab versus chemotherapy/pembrolizumab in patients with PD-L1 >50%, but those data may emerge in the future, concludes Borghaei.
