WATERTOWN, Mass., May 07, 2025 (GLOBE NEWSWIRE) -- C4 Therapeutics, Inc. (C4T) (Nasdaq: CCCC), a clinical-stage biopharmaceutical company dedicated to advancing targeted protein degradation science, today reported financial results for the first quarter ended March 31, 2025, as well as business updates.
“2025 has been marked by focused execution across C4T to generate key data to optimize development plans across our clinical portfolio. With cemsidomide demonstrating compelling overall response rates at multiple dose levels, including one multiple myeloma patient at 100 µg who achieved a minimal residual disease negative complete response, we are prioritizing progressing cemsidomide to the next phase of development to realize its potential to be a best-in-class IKZF1/3 degrader,” said Andrew Hirsch, president and chief executive officer of C4 Therapeutics. “With the achievement of two preclinical milestones in our Roche collaboration, we continue to demonstrate the productivity of our TORPEDO platform to discover highly catalytic, orally bioavailable, and brain penetrant degraders. We remain focused on maximizing our cash runway, which includes advancing cemsidomide and pursuing our internal discovery pipeline focused on targets with a clear degrader rationale and compelling biology applicable to a broad range of therapeutic areas.”
FIRST QUARTER 2025 HIGHLIGHTS AND RECENT ACHIEVEMENTS
Cemsidomide:
Phase 1 dose escalation is complete in multiple myeloma (MM) with the 100 µg once daily (QD) dose level declared safe for expansion; 10 additional patients will be treated in a 100 µg QD expansion cohort to further characterize cemsidomide’s safety and efficacy profile at this dose level.
Cemsidomide MM topline data demonstrate compelling responses rates at multiple doses:
As of the data cutoff date of April 30, 2025, 10 patients have been treated at the 100 µg QD dose level, achieving an overall response rate (ORR) of 50 percent. Notably, one patient who previously progressed on two prior T-cell engager therapies achieved a minimal residual disease (MRD) negative complete response (measured by flow cytometry). Eight patients (80 percent) treated at this dose level received prior CAR-T or T-cell engager therapy.
Since October 11, 2024, six additional patients have been treated for a total of 20 patients treated at the 75 µg QD dose level. As of the data cutoff date of April 30, 2025, the 75 µg QD dose level achieved an ORR of 40 percent.
Cemsidomide remains well-tolerated with manageable neutropenia.
For the non-Hodgkin’s lymphoma (NHL) arm, the Phase 1 dose escalation is ongoing at the 87.5 µg QD dose level and the maximum tolerated dose has not yet been reached.
C4T expects to receive regulatory feedback on registrational development by mid-year 2025.
CFT1946:
Phase 1 dose escalation is complete with 640 mg BID declared as the maximum administered dose. Across the trial, which includes the dose escalation, melanoma and colorectal cancer cohorts, 89 patients were treated.
The pharmacodynamic and safety data, including the data presented at the European Society for Medical Oncology (ESMO) Congress 2024, supports proof of mechanism and the therapeutic potential of degrading the BRAF V600 mutant protein.
Given emerging clinical data and the company’s focus on strategic capital allocation, C4T will not advance CFT1946 beyond the ongoing Phase 1 trial. C4T has made the decision to seek partnership opportunities to advance the BRAF program given the high unmet need and strong degrader rationale for treating BRAF V600 mutant solid tumors.
The CFT1946 Phase 1 data will be presented at a future medical meeting.
CFT8919:
Partner Betta Pharmaceuticals continues to advance the CFT8919 Phase 1 dose escalation trial in Greater China.
Research and Discovery Collaborations:
Advanced Roche collaboration to preclinical milestones. In March 2025, C4T earned a total of $4 million in payments upon achieving certain preclinical milestones for two programs. C4T and Roche continue to advance these programs.
C4T continues to advance its internal research pipeline focused on targets in therapeutic areas in and beyond oncology with a strong degrader rationale and genetic link to disease.

FIRST QUARTER 2025 FINANCIAL RESULTS
Revenue: Total revenue for the first quarter of 2025 was $7.2 million, compared to $3.0 million for the first quarter of 2024. The increase in revenue was primarily due to our collaborations with Merck KGaA, Darmstadt, Germany (MKDG), which commenced in March 2024, as well as our achievement of two preclinical milestones under our Roche collaboration.
Research and Development (R&D) Expense: R&D expense for the first quarter of 2025 was $27.1 million compared to $22.5 million for the first quarter of 2024. The increase in R&D expense was primarily related to clinical trial expenses for cemsidomide and CFT1946, in addition to increased preclinical spend as our research collaborations continue to advance.
General and Administrative (G&A) Expense: G&A expense for the first quarter of 2025 was $9.3 million compared to $10.3 million for the first quarter of 2024. The decrease was primarily a result of reduced personnel costs related to our 2024 restructuring activities.
Net Loss and Net Loss per Share: Net loss for the first quarter of 2025 was $26.3 million, compared to $28.4 million for the first quarter of 2024. Net loss per share for the first quarter of 2025 was $0.37 compared to $0.41 for the first quarter of 2024.
Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of March 31, 2025 were $234.7 million, compared to $267.3 million as of December 31, 2024. The decrease was primarily the result of cash used in operating activities. The balance as of March 31, 2025 is exclusive of the $4.0 million in milestones earned under our Roche collaboration, which the company expects to receive in the second quarter of 2025. The company expects that its cash, cash equivalents and marketable securities as of March 31, 2025 will enable the company to fund its operating plan into 2027.

About Cemsidomide Cemsidomide is an investigational, orally bioavailable small-molecule degrader designed to be a more potent and selective degrader of IKZF1/3, transcription factors that drive multiple myeloma (MM) and non-Hodgkin’s lymphomas (NHL), with unique pharmacokinetic properties. Clinical data has shown that cemsidomide is well-tolerated. In MM, cemsidomide displays evidence of anti-myeloma activity and immunomodulatory effects. In NHL, cemsidomide displays evidence of anti-lymphoma activity. More information may be accessed at www.clinicaltrials.gov (identifier: NCT04756726).
About CFT1946 C4T has advanced preclinical and clinical research to explore how targeted protein degradation may offer improvement over approved therapies that inhibit mutant BRAF V600. C4T advanced CFT1946, an investigational, orally bioavailable brain penetrant small molecule degrader of BRAF V600 mutations in solid tumors into a Phase 1/2 global clinical trial in patients refractory to BRAF inhibitors. CFT1946 is designed to be potent and selective against the BRAF V600 mutant form. In May 2025, C4T announced the decision to not advance its BRAF program beyond the current Phase 1 trial of CFT1946 and seek partnership opportunities to maximize its potential given the high unmet need and strong degrader rationale for treating BRAF V600 mutant solid tumors.
About CFT8919 CFT8919 is an orally bioavailable allosteric degrader that is designed to be potent and selective against EGFR bearing an oncogenic L858R mutation. In preclinical studies, CFT8919 is active in in vitro and in vivo models of L858R driven non-small cell lung cancer. Importantly, CFT8919 retains full activity against additional EGFR mutations that confer resistance against approved EGFR inhibitors including L858R-C797S, L858R-T790M and L858R-T790M-C797S. C4T and Betta Pharmaceuticals have established a strategic partnership to develop CFT8919 in Greater China, where the Phase 1 clinical trial is underway. C4T retains development and commercialization rights for CFT8919 in the United States, European Union and rest of the world.
