“2020 was a highly productive year for CytomX in which we saw our clinical-stage pipeline advance to now encompass Phase 2 evaluations of four Probody therapeutics across nine cancer types, all while contending with the challenges posed by the COVID-19 pandemic. We have demonstrated that our Probody masking technology has the potential to widen or create a therapeutic window for first-in-class and validated oncology targets and we continue to execute on our strategic plan of delivering on the promise of our technology platform for transforming the lives of people with cancer,” said
Business Highlights and Recent Developments
- Presented at the 2020 San Antonio Breast Cancer Symposium updated data from the Phase 1 study of the anti-CD166 conditionally activated antibody-drug conjugate (ADC), praluzatamab ravtansine (CX-2009), in patients with human epidermal growth factor receptor 2 (HER2)-non-amplified breast cancer and translational data demonstrating measurable levels of activated praluzatamab ravtansine in tumor tissue, which supported the launch in
December 2020of a three-arm Phase 2 study. Arms A and B will study praluzatamab ravtansine as a single agent in patients with hormone receptor-positive (HR+), HER2-non-amplified breast cancer and triple-negative breast cancer (TNBC), respectively. Arm C will examine the combination of praluzatamab ravtansine and pacmilimab (CX-072), the Company’s proprietary conditionally activated anti-PD-L1 therapeutic candidate, in TNBC.
- Continued patient enrollment in the Phase 2 expansion study of CX-2029, in partnership with AbbVie, evaluating the anti-CD71 conditionally activated ADC as a single agent in four cohorts: squamous non-small cell lung cancer, head and neck squamous cell carcinoma, esophageal and gastro-esophageal junction cancers, and diffuse large B-cell lymphoma.
- Our partner, Bristol Myers Squibb, continued enrollment in its ongoing, randomized Phase 1/2a study of BMS-986249 in patients with previously-untreated unresectable stage III-IV melanoma and expanded the scope of the Part 2b evaluation to include three new cohorts, enrolling patients with advanced hepatocellular carcinoma, metastatic castration-resistant prostate cancer, and unresectable locally advanced or metastatic TNBC. BMS also continued enrollment into a Phase 1 study of a second anti-CTLA-4 Probody, BMS-986288.
- Advancement of our third conditionally activated ADC, CX-2043, into investigational new drug (IND)-enabling studies. CX-2043 is directed against the epithelial cell adhesion molecule (EpCAM/Trop-1), a high potential target with elevated expression on a wide variety of tumor types.
- Continued IND-enabling studies for CX-904, our most advanced program in the new and promising modality of T-cell engaging bispecific antibodies. CX-904, partnered with Amgen, targets the epidermal growth factor receptor on tumor cells and the CD3 receptor on T cells.
- Continued drug discovery activities for conditionally activated T-cell engaging bispecific antibodies as part of our strategic collaboration with Astellas.
- Appointed new Board member Dr.
- Strengthened balance sheet with approximately
$108 millionraised from a follow-on public equity offering.
- Report initial data from the praluzatamab ravtansine (CX-2009) Phase 2 study in the fourth quarter of 2021.
- Report initial data from the CX-2029 Phase 2 expansion study in the fourth quarter of 2021.
- Submit IND applications for CX-2043 and CX-904 in late 2021.
- Virtual analyst and investor briefing with Key Opinion Leaders in
April 2021to discuss our Probody technology platform with focus on praluzatamab ravtansine and CX-2029.

Conference Call & Webcast Information
CytomX management will host a conference call today at
CytomX 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 conditionally activated 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 conditionally activated antibodies 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 comprises five assets, four of which are in Phase 2 clinical studies. First-in-class product candidates against previously undruggable targets include a CD166-targeting conditionally activated antibody-drug conjugate wholly owned by CytomX (praluzatamab ravtansine, CX-2009) and a CD71-targeting conditionally activated antibody-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 the CTLA-4-targeting Probodies, BMS-986249 and BMS-986288, partnered with Bristol Myers Squibb, and our wholly-owned conditionally activated anti-PD-L1 antibody, pacmilimab (CX-072).
