There are four molecules in the EDO pipeline:
1. Tinostamustine (EDO-S101) is an AK-DACi (a first-in-class alkylating deacetylase inhibiting molecule) that, in preclinical studies, has been shown to improve access to the DNA strands within cancer cells, break them and counteract damage repair.1-3 Preclinical studies suggest that these complementary and simultaneous modes of action have the potential to overcome resistance.3,4
2. Etoposide toniribate (EDO-S7.1) is a prodrug initially in development for the treatment of biliary tract cancer.
3. EDO-B776 is an antibody-drug conjugate (ADC) targeting a fragment of cancer antigen 125 (CA125) and is being developed to treat ovarian cancer.
4. EDO-B278 is an ADC targeting the human tissue factor and is in development to treat various solid tumours.
