The AccuTOXTM programme consists of using a lead variant of the AccumTM molecule to trigger cell death in cancer cells. When combined with the immune-checkpoint inhibitor CTLA-4, this lead AccumTM triggered a potent anti-tumoral response in several cancer models including, T-cell lymphoma, melanoma, colon, and breast cancer. Defence plans to use AccuTOXTM in its Phase I to treat breast cancer patients in quarter four of 2022.
