- premise rilvegostomig is a PD-1xTIGIT bispecific; vs pembrolizumab its only differentiator is TIGIT blockade, on the same immune-synapse axis PD-1 already addresses
- premise anti-TIGIT on a PD-(L)1 backbone failed to improve outcomes in the SKYSCRAPER-01 phase 3 resolved_trial:NCT04294810
- inference TIGIT is target-redundant against the backbone in 1L NSCLC
- prediction no OS superiority over pembrolizumab; primary endpoint not met
