Invion Limited announced that following extensive research and development (R&D) efforts, it has selected a new Active Pharmaceutical Ingredient (API) to progress with. Provisional patents relating to the new API, called INV-043, have been filed and initial tests carried out by Invion's research partner, the Hudson Institute of Medical Research (Hudson Institute), indicate that INV-043 has greater anticancer activity and better cancer-targeting characteristics than previous generations of APIs developed by Invion. Hudson Institute is finalising work on initial proof-of-concept models testing ablation in three cancer types; triple negative breast cancer, T-cell lymphoma and pancreatic cancer, using immune deficient mice. Invion aims to finalise the findings in the coming weeks. Further, Hudson is commencing additional proof-of-concept work with INV-043 on immunocompetent in vivo models. The results from these proof-of-concept models will help shape Invion's R&D program, timelines and target indications.
