Abstract Lessons Learned Bintrafusp alfa had a manageable safety profile and demonstrated preliminary clinical activity in heavily pretreated patients with solid tumors (including hepatocellular carcinoma) no or limited treatment options. Findings from this study suggest bintrafusp may be novel therapeutic approach for advanced tumors. Additional trials are needed to further explore efficacy of specific tumor types. Background is first-in-class bifunctional fusion protein composed the...
