Data on second-line therapy with pembrolizumab after chemotherapy showed a lower response rate of approximately 21%. Brahmer suggests that receiving chemotherapy before pembrolizumab may not be beneficial, particularly for patients who express high levels of PD-L1.
Many in the field are moving away from single-agent pembrolizumab, says Brahmer, specifically in the treatment of patients with nonsquamous cell histologies. However, cohort G of the KEYNOTE-021 study showed higher response rates with the combination of pembrolizumab, carboplatin and pemetrexed compared with carboplatin and pemetrexed alone in NSCLC.
