Key Business Updates

• Encouraging Interim Results for CX-2051 in Advanced Colorectal Cancer: CytomX Therapeutics, Inc., a leader in masked, conditionally activated biologics, reported positive interim data from its ongoing Phase 1 study of CX-2051, a first-in-class EpCAM Antibody Drug Conjugate (ADC), in patients with advanced colorectal cancer (CRC). The clinical data highlighted CX-2051’s targeted design, demonstrating promising therapeutic potential for a disease that remains difficult to treat in late-line settings. Following the favorable outcomes, the company has advanced the program into dose expansions at 7.2 mg/kg, 8.6 mg/kg, and 10 mg/kg administered every three weeks, with a Phase 1 data update expected by the first quarter of 2026. Planning is also underway for the initiation of a Phase 2 trial in the first half of 2026, along with potential combination studies in earlier stages of CRC.
• Pipeline Expansion with CX-801 Combination Therapy: In addition to progress with CX-2051, CytomX continued development of CX-801, a masked interferon alpha-2b (PROBODY) molecule. The Phase 1 monotherapy dose escalation remains ongoing, with initial pharmacokinetic, pharmacodynamic, and tumor biomarker data anticipated in the fourth quarter of 2025. In May 2025, CytomX initiated a combination dose escalation study of CX-801 with Merck’s KEYTRUDA® (pembrolizumab) in patients with advanced melanoma. This combination aims to enhance the anti-tumor immune response while maintaining safety and tolerability. Early clinical data for the combination therapy are expected in 2026, further supporting CytomX’s strategy to expand the therapeutic applicability of its PROBODY platform.
• Financial Strength Bolstered by Successful Capital Raise: The company significantly strengthened its financial position during the quarter through the successful completion of a USD 100 million underwritten common stock offering, resulting in net proceeds of USD 93.4 million. As of June 30, 2025, CytomX held USD 158.1 million in cash, cash equivalents, and investments, compared to USD 79.9 million as of March 31, 2025. The improved liquidity provides the company with a projected cash runway through the second quarter of 2027, ensuring continued support for the advancement of key pipeline programs and strategic collaborations.
• Strategic Collaborations and Research Advancements: CytomX continued to demonstrate strong momentum across its collaborative research programs. The company presented preclinical data, developed in partnership with Moderna, on an mRNA-encoded masked IL-12 molecule at the AACR Annual Meeting. The data revealed robust anti-tumor activity and significantly enhanced tolerability compared to unmasked IL-12. Additionally, multiple discovery-stage programs are advancing under ongoing collaborations with leading pharmaceutical partners, including Bristol Myers Squibb, Amgen, Astellas, Regeneron, and Moderna, with a primary focus on developing next-generation bispecific immunotherapies and T-cell engagers.
• Reduced Operating Costs and Streamlined R&D Investment: CytomX achieved a notable reduction in operating expenses during the second quarter of 2025, reflecting disciplined cost management and focused R&D prioritization. Total operating expenses decreased to USD 19.9 million from USD 33.6 million in the same quarter of 2024. Research and development expenses were USD 13.3 million, down from USD 25.2 million in the prior-year period. The decline primarily resulted from the absence of a USD 5 million milestone payment made to Immunogen in 2024, reduced spending on the deprioritized CX-904 program, and cost savings stemming from a restructuring implemented in early 2025.
• Efficiency Gains in Administrative Operations: General and administrative expenses declined to USD 6.6 million in Q2 2025, a reduction of USD 1.8 million compared to the same period in 2024. This improvement was driven by lower personnel costs, as well as reductions in patent and legal-related expenditures. The company’s ongoing efforts to optimize administrative efficiency have contributed to an overall leaner cost structure, aligning resources toward advancing high-priority clinical and research initiatives.
• Outlook and Strategic Priorities: Looking ahead, CytomX remains focused on driving its next major clinical and corporate milestones. The company anticipates sharing an updated Phase 1 dataset for CX-2051 in approximately 70 patients by the first quarter of 2026, followed by the initiation of a Phase 2 study in the first half of 2026. In parallel, the ongoing CX-801 clinical programs are expected to yield important preliminary data by late 2025 and into 2026. Supported by a strengthened financial position and robust partnerships, CytomX continues to advance its mission to redefine targeted oncology through innovative, conditionally activated biologic therapeutics.
