The reporting lives at Inova Newsroom. Our summary is checked against it, and we link it on every story.

Inova Schar, in the Fairfax and Falls Church area, was a top-enrolling site for INTerpath-001, a Phase 3 study in melanoma. Adding the investigational treatment intismeran autogene to the immunotherapy Keytruda cut the risk of recurrence or death by 42% compared with Keytruda alone, Inova reported.

At two years, 82.2% of patients on the combination were cancer-free, versus 70% on Keytruda alone. The treatment is not FDA-approved. Overall survival is still maturing, so this result is about recurrence, not a finished survival verdict and not a cure.
