CytomX Therapeutics Announces Third Quarter 2021 Financial Results

and Provides Business Update

-Initial data release from Phase 2 study of CX-2029 remains on track for fourth quarter 2021-

-Initial data release from Phase 2 study of praluzatamab ravtansine (CX-2009) expected in 2022-

SOUTH SAN FRANCISCO, Calif., November 4, 2021 – CytomX Therapeutics, Inc. (Nasdaq: CTMX), a leader in the field of conditionally activated therapeutics, today reported third quarter 2021 financial results and provided a business update.

“With intense focus on execution, the CytomX team made significant progress with clinical site initiation and patient enrollment during the past quarter. As a result, we remain on track to announce initial data by year end from our ongoing Phase 2 expansion study evaluating CX-2029 in defined cancer types,” said Sean McCarthy, D.Phil., president, chief executive officer and chairman of CytomX Therapeutics. “We also remain on track for initial data from the praluzatamab ravtansine Phase 2 breast cancer clinical program in 2022. In addition, we are expanding the reach of our versatile platform with anticipated fourth quarter IND filing for our first conditionally activated T-cell bispecific antibody, CX-904, and with the presentation at SITC 2021 of our emerging drug discovery work in the field of conditional cytokines,” added Dr. McCarthy.

Third Quarter Business Highlights and Recent Developments

 Clinical site activation and patient enrollment for the ongoing Phase 2 study of CytomX’s wholly owned conditional antibody-drug conjugate (ADC), praluzatamab ravtansine (CX-2009), made substantial progress, including opening additional sites in U.S., Europe, and Asia, as well as partnering with patient advocacy groups to encourage enrollment from underrepresented populations. Praluzatamab ravtansine is currently being evaluated in a Phase 2 study as monotherapy in patients with human epidermal growth factor receptor 2-non-amplified breast cancer and, in combination with pacmilimab (CX-072), in patients with triple-negative breast cancer. Initial data from this study is on track for 2022.

 Patient enrollment into the expansion cohorts continued for the Phase 2 study of CX-2029, evaluating the CD71-directed conditionally activated ADC co-developed by CytomX and AbbVie in four cancer indications: squamous non-small cell lung cancer, head and neck squamous cell carcinoma, esophageal and gastro-esophageal junction cancers, and diffuse large B-cell lymphoma. Initial data from this study is on track for the fourth quarter of 2021.

 BMS-986249, a Probody version of ipilimumab, continued to be studied by Bristol Myers Squibb, CytomX’s collaboration partner, in combination with nivolumab, the anti-PD-1 antibody, across four different advanced malignancies: melanoma, hepatocellular carcinoma, castration-resistant prostate cancer, and triple-negative breast cancer. Bristol Myers Squibb is also evaluating BMS-986288, a Probody version of non-fucosylated ipilimumab, as monotherapy or in combination with nivolumab, in a Phase 1 study.

 CytomX expects to submit an investigational new drug application for CX-904 to the U.S. Food and Drug Administration in late 2021. CX-904 is a conditionally activated T-cell-engaging bispecific antibody candidate against the epidermal growth factor receptor on tumor cells and CD3 on T cells and is partnered with Amgen.

 A CytomX abstract highlighting company progress in the field of conditionally active cytokines has been accepted for poster presentation at the Society for Immunotherapy of Cancer (SITC) 36th Annual Meeting (SITC 2021), which will be held from November 12-14, 2021 at the Walter E. Washington Convention Center, Washington, DC. This presentation will detail the preclinical characterization and improved therapeutic index of a masked interferon alpha-2b (IFN-a2b) leveraging CytomX proprietary conditional activation technologies.

 CytomX published a preclinical study in Cancer Immunology Research showing that systemic administration of conditionally activated anti-programmed cell death ligand 1 (anti-PD-L1) and anti-programmed cell death protein 1 (anti-PD-1) antibodies to tumor-bearing mice elicited antitumor activity similar to that of traditional PD-1/PD-L1-targeted antibodies, but with reduced systemic immune-mediated toxicity. These data provide further preclinical rationale to support the ongoing development of pacmilimab (CX-072), currently in a Phase 2 study in combination with praluzatamab ravtansine in patients with TNBC. The preclinical article can be accessed at https://cancerimmunolres.aacrjournals.org/content/canimm/early/2021/10/11/2326-6066.CIR-21-0031.full.pdf.

 CytomX appointed Alan Ashworth, Ph.D., FRS, a world-renowned expert in cancer research and a global leader in cancer therapy development, to its board of directors.

Third Quarter 2021 Financial Results

Cash, cash equivalents, and investments totaled $336 million as of September 30, 2021, compared to $316 million as of December 31, 2020.

Revenue was $18 million for the three months ended September 30, 2021, relatively flat when compared to the corresponding period in 2020.

Research and development expenses increased $5 million during the three months ended September 30, 2021 to $29 million compared to the corresponding period in 2020. The increase was driven mainly by personnel, clinical trial, and consulting and contract service expenses primarily related to praluzatamab ravtansine and CX-2029.

General and administrative expenses increased $2.5 million during the three months ended September 30, 2021 to $11 million compared to the corresponding period in 2020. The increase was attributable to personnel related and recruiting expenses as well as professional services.

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 and

successfully leverage therapeutic targets that were once thought to be inaccessible. CytomX’s robust and differentiated pipeline includes the wholly-owned praluzatamab ravtansine (CX-2009), an investigational conditionally activated antibody-drug conjugate (ADC) directed toward CD166, and CX-2029, an investigational conditionally activated ADC directed toward CD71 co-developed with AbbVie. These two programs are currently being evaluated in Phase 2 studies, targeting a variety of late-stage, difficult-to-treat cancer types, including breast cancer for praluzatamab ravtansine, and squamous non-small cell lung cancer, and head and neck squamous cell carcinoma for CX-2029. CytomX’s clinical pipeline also includes cancer immunotherapeutic candidates against validated targets such as the CTLA-4-targeting Probody therapeutics, BMS-986249 and BMS-986288, partnered with Bristol Myers Squibb, and our wholly-owned conditionally activated anti-PD-L1 antibody, pacmilimab (CX-072).
