TACTI-002 is where the rub is - thus far Keytruda mono has a 20% response rate in NSCLC (80% of all lung cancer) The FDA’s initial approval of Keytruda (pembrolizumab)immunotherapy was based in part on data from the KEYNOTE-001 clinical trial,which initially showed that Keytruda alone had an overall response rate ofnearly 20% among previously treated and treatment-naive patients with advancedNSCLC whose cancers expressed high levels of PD-L1.Noting FDA approval for Keytruda in this setting is only for high PD-1 expression.
Keytruda and Efti in NSCLC - 47% overall response rate. Admittedly small cohort BUT this is for allcomer PD-1 status....
