Defence Therapeutics Expands Radiopharmaceutical Development Strategy with Alpha and Beta-Emitter Programs
xCruzo Brief
Defence Therapeutics says it’s expanding its Accum platform radiopharmaceutical development to evaluate both alpha- and beta-emitting radioisotopes. In an announcement dated August 31, 2026, the Montreal-based company (CSE: DTC; OTCQB: DTCFF; FSE: DTC) said the move is meant to broaden Accum’s capability for intracellular transport, improving delivery of payloads into cancer cells. The program will compare alpha emitters, including Actinium-225, for high-energy, short-range damage, and beta emitters like Lutetium-177 for medium-energy, longer-range penetration. Defence aims to generate comparative pharmacology, efficacy, and safety data using preclinical work to advance Accum-enabled radio-immunoconjugates toward clinical development.
