In addition, we are also exploring short term opportunities to support a funded preclinical validation for VAL401 through our wholly owned subsidiary, Inaphaea Biolabs Limited, which has 19 pancreatic Patient Derived Cell models. These models can be applied in 3D systems as New Approach Methods which are receiving growing support from the FDA in support for IND submissions."

Broadening the potential for VAL401, Ambrose intends to work with ValiRx's Inaphaea to generate pre-clinical evidence in multiple other cancer indications, starting with pancreatic models. We are eager to accelerate its development, with expanded clinical trials and expedited regulatory submissions, to broaden the impact of this innovative therapy to patients worldwide."
