– CX-2051 is tailored for treatment of EpCAM-expressing cancers by matching target expression and tumor sensitivity with a topoisomerase-1 inhibitor payload –
– Preclinical data demonstrate a favorable predicted therapeutic index and efficacy across multiple EpCAM-expressing tumors, including colorectal cancer (CRC) –
– CX-2051 IND filing expected by year-end 2023 –
SOUTH SAN FRANCISCO, CA, USa I October 18, 2023 I CytomX Therapeutics, Inc. (Nasdaq: CTMX), a leader in the field of conditionally activated, localized biologics, today announced that the Company presented data characterizing the preclinical profile of its EpCAM-targeting ADC, CX-2051, at the World ADC conference taking place October 16-19, 2023, in San Diego, CA.
“CX-2051 is designed to address the unmet needs of patients with EpCAM-expressing tumors, including colorectal cancer, where EpCAM expression is uniformly high. EpCAM is a broadly expressed, validated anti-cancer target that to date has been limited in its development potential due to systemic, on-target off-tumor dose-limiting toxicities”, said Marcia P. Belvin, Ph.D., senior vice president and chief scientific officer at CytomX.
Continued Dr. Belvin, “Based on our experience with the Probody® Platform and our clinical experience with Probody-ADCs, we have designed CX-2051 to mask target binding in normal tissues and include a next-generation topoisomerase-1 inhibitor payload. We are encouraged by the compelling preclinical profile of CX-2051 and anticipate filing an IND for the program by the end of the year. We aim to launch Phase 1 dose escalation for CX-2051 in solid tumors in 2024, with an initial focus in metastatic colorectal cancer as a priority indication.”

About CytomX Therapeutics
CytomX is a clinical-stage, oncology-focused biopharmaceutical company focused on developing novel conditionally activated biologics localized to the tumor microenvironment. By pioneering a novel class of conditionally activated biologics, powered by its Probody® technology platform, CytomX’s goal is to transcend the limits of current cancer treatments. CytomX’s robust and differentiated pipeline comprises therapeutic candidates across multiple treatment modalities including antibody-drug conjugates (“ADCs”), T-cell engaging bispecific antibodies, and immune modulators such as cytokines and checkpoint inhibitors. CX-2029 is an investigational conditionally activated ADC directed toward CD71. CytomX’s clinical pipeline also includes cancer immunotherapeutic candidates against validated targets such as the CTLA-4-targeting Probody therapeutic BMS-986288, partnered with Bristol Myers Squibb, and CX-904, a conditionally activated T-cell-engaging bispecific antibody targeting the epidermal growth factor receptor (EGFR) on tumor cells and the CD3 receptor on T cells, partnered with Amgen. In addition, CytomX has a diverse preclinical portfolio of wholly-owned assets including CX-801, an interferon alpha-2b Probody cytokine that has broad potential applicability in traditionally immuno-oncology sensitive as well as insensitive (cold) tumors and CX-20511, a conditionally activated ADC directed toward EpCAM, with potential applicability across multiple EpCAM-expressing epithelial cancers. CytomX has also established strategic collaborations with multiple leaders in oncology, including Amgen, Astellas, Bristol Myers Squibb, Regeneron and Moderna.
