SOUTH SAN FRANCISCO, Calif., Dec. 03, 2020 (GLOBE NEWSWIRE) -- CytomX Therapeutics, Inc. (Nasdaq: CTMX), a clinical-stage oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody® technology platform, today announced two poster presentations at the 2020 Virtual San Antonio Breast Cancer Symposium (SABCS) taking place from December 8-11, 2020. Abstracts are available to the public online on the SABCS website at www.sabcs.org.
"We are pleased to be presenting at this key breast cancer symposium exploratory translational studies of praluzatamab ravtansine, CX-2009, as well as the design of our new phase 2 study investigating CX-2009 alone or in combination with pacmilimab, our Probody therapeutic to PD-L1, in patients with HER2-non amplified breast cancer," commented Amy Peterson, M.D., chief development officer of CytomX Therapeutics. "The phase 1 clinical data for CX-2009, previously presented and updated here, reinforce the potential for this first in class molecule to achieve clinically meaningful outcomes in patients with advanced breast cancers and our capability to leverage the Probody platform to drug previously elusive targets."
Details on CytomX's presentations at the 2020 SABCS are below:

Title: A Phase 2, open-label study to evaluate the safety and efficacy of the probody therapeutic (Pb-Tx) CX‑2009 in metastatic HR-Positive/HER2-negative breast cancer (mHR+/HER2− BC) and of CX-2009 as monotherapy and in combination therapy with CX-072 in metastatic triple-negative breast cancer (TNBC) Poster Number: OT-03-08 Lead Author: Kathy Miller, M.D., Indiana University Simon Cancer Center Poster Session : Ongoing Trials Posters: Antibody-drug Conjugates Poster Session Date: Wednesday, December 9, 2020: 9:00 AM ET
About CytomX TherapeuticsCytomX is a clinical-stage, oncology-focused biopharmaceutical company with a vision of transforming lives with safer, more effective therapies. We are developing a novel class of investigational antibody therapeutics, based on our Probody® technology platform, for the treatment of cancer. CytomX has strategic drug discovery and development collaborations with AbbVie, Amgen, Astellas, and Bristol Myers Squibb.
Probody therapeutics are designed to remain inactive until they are activated by proteases in the tumor microenvironment. As a result, Probody therapeutics are intended to bind selectively to tumors and decrease binding to healthy tissue, to minimize toxicity and potentially create safer, more effective therapies. As leaders in the field, our innovative technology is designed to turn previously undruggable targets into druggable targets and to enable more effective combination therapies. CytomX and its partners, comprised of leading biotechnology and pharmaceutical companies, have developed a robust pipeline of potential first-in-class therapeutic candidates against novel, difficult to drug targets and potential best-in-class immunotherapeutic candidates against clinically validated targets. The CytomX clinical stage pipeline includes first-in-class product candidates against previously undruggable targets, including a CD166-targeting Probody drug conjugate wholly owned by CytomX (CX-2009) and a CD71-targeting Probody drug conjugate partnered with AbbVie (CX-2029). CD166 and CD71 are among cancer targets that are considered to be inaccessible to conventional antibody drug conjugates due to their presence on many healthy tissues. The CytomX clinical stage pipeline also includes cancer immunotherapeutic candidates against validated targets such as our wholly owned anti-PD-L1 Probody therapeutic, CX-072, and the CTLA-4-targeting Probody therapeutics, BMS-986249 and BMS-986288, partnered with Bristol Myers Squibb.
