By pioneering a novel pipeline of localized biologics, powered by its PROBODY<sup>\u00ae<\/sup> therapeutic platform, CytomX\u2019s vision is to create safer, more effective therapies for the treatment of cancer. CytomX\u2019s robust and differentiated pipeline comprises therapeutic candidates across multiple treatment modalities including antibody-drug conjugates (\u201cADCs\u201d), T-cell engagers, and immune modulators such as cytokines. CytomX\u2019s clinical-stage pipeline includes varsetatug masetecan (formerly CX-2051) and CX-801. Varseta-M is a masked, conditionally activated ADC directed toward epithelial cell adhesion molecule (EpCAM), armed with a topoisomerase-1 inhibitor payload and was discovered in collaboration with ImmunoGen, now part of AbbVie. EpCAM is a highly expressed but previously undruggable tumor antigen due to expression on normal tissues. Varseta-M is designed to open a therapeutic window for this high potential target and deliver meaningful anti-cancer activity in solid tumors, including CRC. CX-801 is a masked interferon alpha-2b PROBODY<sup>\u00ae<\/sup> cytokine with broad potential applicability in traditionally immuno-oncology sensitive as well as insensitive (cold) tumors. CytomX has established strategic collaborations with multiple leaders in oncology, including Amgen, Astellas, Bristol Myers Squibb, Regeneron and Moderna.
