CytomX is unlocking the potential of antibody therapeutics in oncology by developing a novel therapeutic antibody class of highly targeted Probody therapeutics. The Company's Probody Platform allows to design drugs that selectively activate in the tumor microenvironment while reducing drug activity in healthy tissue and in circulation. This ability to localize therapeutic effects to the tumor reduces systemic toxicity, with potential for safer and more effective therapies for a broad array of validated and previously inaccessible oncology targets. Driven by a vision to transform patient lives, CytomX is an advancing multiple Probody cancer immunotherapies and Probody drug conjugates toward clinical investigation, while also applying its technology to bispecific T-cell engaging antibodies and ProCAR-NK cell therapies.
