SOUTH SAN FRANCISCO, Calif., May 8, 2024 – CytomX Therapeutics, Inc. (Nasdaq: CTMX), a leader in the field of masked, conditionally activated biologics, today reported first quarter 2024 financial results and provided a business update.

 

“CytomX’s multi-modality PROBODY® therapeutic pipeline encompasses some of the most exciting areas of current oncology R&D, including T-cell engagers, ADCs, and cytokines. CytomX’s leadership and continuous innovation in the field of masked, conditionally activated biologics ideally positions us to develop novel, potent therapies for cancer patients in key areas of unmet need,” said Sean McCarthy, D.Phil., chief executive officer and chairman of CytomX.

 

McCarthy added, “CytomX entered 2024 executing to our plan and with substantial momentum, looking towards key data readouts from our multi-modality PROBODY® therapeutic pipeline over the next 12 to 24 months. Our exciting announcement today of positive initial Phase 1a clinical data for CX-904 marks the beginning of this data-rich period and we look forward to making continued progress with our broad program of masked, PROBODY® T-cell engagers and to also demonstrating clinical proof of concept for CX-2051 and CX-801, for which we anticipate initial Phase 1 data in 2025.”

 

First Quarter Business Highlights and Recent Developments

 

Pipeline

CX-904, PROBODY® T-cell-engager (TCE) targeted to EGFRxCD3, demonstrates a favorable safety profile and encouraging anti-cancer activity in Phase 1 dose escalation. Dose escalation continues.

CX-904 is a conditionally activated PROBODY TCE designed to target the epidermal growth factor receptor (EGFR) on cancer cells and the CD3 receptor on T cells within the tumor microenvironment. CX-904 is being evaluated in an ongoing Phase 1 study.

Today, the Company announced positive initial Phase 1 dose escalation data in heavily pre-treated patients with advanced metastatic solid tumor types that are generally known to express EGFR. 19 patients were initially enrolled into non-step dosing cohorts with target doses ranging from 0.007 mg to 6 mg. 16 patients were subsequently enrolled into step-dosing cohorts with target doses ranging from 5 mg to 10 mg and with tocilizumab prophylaxis. Dose escalation continues and enrollment into a cohort with a target dose of 15 mg is ongoing.

---

CX-2051, an EpCAM-directed PROBODY® antibody drug conjugate, first patient dosed in Phase 1 in April 2024, initial data expected in 2025.

EpCAM is a promising oncology target with significant potential that is highly expressed across many indications including colorectal, gastric, endometrial, and ovarian cancers. EpCAM has been clinically validated by locally administered, previously approved cancer therapies. To date, systemically administered anti-EpCAM therapeutics have been unsuccessful due to toxicities in certain epithelial tissues. CX-2051 utilizes a cytotoxic payload that is a derivative of camptothecin, a topoisomerase-1 inhibitor, a class of drug that has shown potent clinical anti-cancer activity in the ADC context for multiple targets and cancer types. CX-2051 has demonstrated a wide predicted therapeutic index in multiple preclinical models, constituting an opportunity for broad clinical use in large patient populations.

CX-801, a dually-masked PROBODY® interferon-alpha 2b, advancing to Phase 1 in Q2 2024. Executed Clinical Collaboration Agreement with Merck (known as MSD outside of the US and Canada) to evaluate CX-801 in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab).

Interferon-alpha 2b is an immunotherapeutic cytokine that has demonstrated clinical activity and gained regulatory approval previously in multiple cancer types, including locally advanced or metastatic melanoma, renal cancer and bladder cancer. IFNα2b provides a potentially superior approach to activating anti-tumor immune responses compared to other cytokines but its clinical benefit has been limited to date by severe dose-limiting toxicities. CX-801 is an optimized, dually masked, conditionally activated IFNα2b, designed to have an expanded therapeutic index that has the potential to become a cornerstone of combination therapy for a wide range of tumor types.

CytomX continues to make progress in its R&D partnerships.

CytomX has multiple active research and development partnerships and more than 10 ongoing research programs with major biotechnology and pharmaceutical companies (Amgen, Astellas, Bristol Myers Squibb, Moderna and Regeneron). The majority of these programs are focused on masked, conditionally activated PROBODY® T-cell engagers.

In Q1 2024, CytomX achieved $10.0 million in milestones under its multi-target T-cell Engager collaboration with Astellas related to two separate PROBODY® TCE programs:

2024 Priorities and Key Milestones:

Q1 2024 Financial Results

Cash, cash equivalents and investments totaled $150.3 million as of March 31, 2024, compared to $174.5 million as of December 31, 2023. The cash balance as of March 31, 2024, does not include the $10.0 million of Astellas milestone achievements earned in the first quarter of 2024.

 

Total revenue was $41.5 million for the three months ended March 31, 2024 compared to $23.5 million for the corresponding period in 2023. The increase in revenue was driven primarily by a higher percentage of work completion of existing targets under the BMS, Moderna and Regeneron agreements as well as the $10.0 million of milestones earned under the collaboration with Astellas.

 

Research and development expenses increased by $0.9 million for the three months ended March 31, 2024 to $22.1 million, compared to $21.2 million for the corresponding period of 2023. This was primarily due to increased laboratory contract services and manufacturing activities related to CX-904, CX-2051 and other wholly owned and partnered

---

programs, as well as consulting, personnel and license related expenses, offset by decreased manufacturing activities for CX-801 program and winding down of clinical study activities related to the CX-2009 and CX-2029 programs.

 

General and administrative expenses decreased by $0.2 million for the three months ended March 31, 2024 to $7.8 million compared to $8.0 million for the corresponding period of 2023, primarily due to lower building rent as a result of partial sublease of the Company’s headquarters.

 

Conference Call & Webcast

CytomX management will host a conference call and simultaneous webcast today at 5 p.m. EDT (2 p.m. PDT) to discuss the financial results and provide a business update. Participants may access the live webcast of the conference call from the Events and Presentations page of CytomX’s website at https://ir.cytomx.com/events-and-presentations. Participants may register for the conference call here and are advised to do so at least 10 minutes prior to joining the call. An archived replay of the webcast will be available on the company’s website.

By pioneering a novel pipeline of localized biologics, powered by its PROBODY® therapeutic platform, CytomX’s vision is to create safer, more effective therapies for the treatment of cancer. CytomX’s robust and differentiated pipeline comprises therapeutic candidates across multiple treatment modalities including antibody-drug conjugates (“ADCs”), T-cell engagers, and immune modulators such as cytokines. CytomX’s clinical-stage pipeline includes CX-904, CX-2051 and CX-801. CX-904 is a masked, conditionally activated T-cell-engaging bispecific antibody targeting the epidermal growth factor receptor (EGFR) on tumor cells and the CD3 receptor on T cells. CX-904 is partnered with Amgen in a global co-development alliance. CX-2051 is a masked, conditionally activated ADC directed toward epithelial cell adhesion molecule, EpCAM, with potential applicability across multiple EpCAM-expressing epithelial cancers. CX-2051 was discovered in collaboration with Immunogen, now part of AbbVie. CX-801 is a masked interferon alpha-2b PROBODY® 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.
