Antibody-drug conjugates can deliver chemotherapy directly to tumors but more than 95 percent of the dose often ends up in healthy tissues, decreasing efficacy and increasing toxicity. Mythic Therapeutics FateControl technology improves the uptake of ADCs in cancerous cells while avoiding the release of their toxic payloads in healthy ones. This promises to increase efficacy of these therapies in a wide range of cancers without causing unacceptable side-effects. We spoke to Brian Fiske, co-founder, chief scientific officer of Mythic, about the challenges that have held back the benefits of ADCs, how the company’s FateControl technology addresses those, and how it is thinking of building a pipeline of ADCs across indications.
