Within the last year, physicians have seen frontline data from the IMpower131 and KEYNOTE-407 trials. IMpower131 looked at the combination of taxane-based doublet chemotherapy plus atezolizumab (Tecentriq). Though the study had shown significant progression-free survival (PFS) benefit, it failed to translate into an overall survival (OS) benefit, says Halmos.
The KEYNOTE-407 study looked at the combination of carboplatin/paclitaxel or nab-paclitaxel (Abraxane), plus or minus pembrolizumab (Keytruda). This was followed by maintenance pembrolizumab versus placebo. The addition of pembrolizumab showed a PFS benefit as well as a substantial OS benefit, irrespective of PD-L1 expression, adds Halmos. This translated to an approximately 20% improvement in response rates, changing the frontline standard, concludes Halmos.
