The trial aims to enroll 61 patients across various solid tumor indications.

The big picture

Radiopharm Theranostics' progression to a higher dose cohort in its BetaBart trial underscores the growing interest in radiopharmaceuticals for oncology. The B7-H3 target represents a compelling opportunity given its broad expression across multiple tumor types. The company's collaboration with MD Anderson Cancer Center further validates its development strategy, though success will hinge on demonstrating differentiated efficacy in a competitive landscape.
