"The first half of 2025 was driven by focused execution across our business with the achievement of several research milestones with our collaborators and within our internal preclinical pipeline, the advancement of cemsidomide toward label-enabling trials and continued financial discipline that resulted in extending cash runway. We recently completed enrollment in the ongoing cemsidomide Phase 1 trials in multiple myeloma and non-Hodgkin’s lymphoma and look forward to sharing the full Phase 1 multiple myeloma data in September, which we believe further demonstrate cemsidomide’s best-in-class potential. Our recent Type C meeting with the FDA enabled refinement of our cemsidomide registrational development plans and we remain on track to initiate registrational development in early 2026," said Andrew Hirsch, president and chief executive officer of C4 Therapeutics. "Additionally, as part of C4T’s commitment to strategic capital allocation and despite cemsidomide’s compelling response rates observed in non-Hodgkin’s lymphoma, we are prioritizing cemsidomide multiple myeloma registrational development as we believe this has the highest potential for patient impact and value creation."
SECOND QUARTER 2025 HIGHLIGHTS AND RECENT ACHIEVEMENTS
Cemsidomide:
Completed enrollment and dose escalation for the Phase 1 trial of cemsidomide in multiple myeloma (MM) and non-Hodgkin’s Lymphoma (NHL). Cemsidomide continued to demonstrate a well-tolerated profile and compelling response rates in MM and NHL. The highest dose level studied in both indications was 100 µg once daily (QD).
Data from the cemsidomide Phase 1 trial in MM was accepted as an oral presentation at the International Myeloma Society (IMS) Annual Meeting taking place from September 17 – September 20, 2025 in Toronto, Canada. The presentation will include data from all safety and efficacy evaluable MM patients from all dose levels studied.
C4T had a productive Type C meeting with the U.S. Food and Drug Administration (FDA) that enabled further refinement of the cemsidomide registrational development plan. By year-end 2025, C4T expects to align with the FDA on a recommended Phase 2 dose based on the existing Phase 1 MM data.
Additionally, C4T is on track to initiate registrational development in early 2026. The next phase of development will evaluate cemsidomide in combination with dexamethasone in the late-line MM setting and in combination with a B-cell maturation antigen bispecific T-cell engager (BCMA BiTE) for earlier lines of MM treatment.
CFT8919:
Partner Betta Pharmaceuticals continues to advance the CFT8919 Phase 1 dose escalation trial in Greater China.
Research and Discovery Collaborations:
C4T advanced its collaboration with Merck KGaA, Darmstadt, Germany (MKDG), which is focused on two projects within the KRAS family, to a milestone on one of these projects. C4T earned $1 million upon achieving this milestone.
C4T has identified multiple degraders against two novel targets outside of oncology, which are now advancing into the next phase of discovery.
KEY UPCOMING MILESTONES AND DATA PRESENTATIONS

Management will host an investor call to discuss cemsidomide data in MM in conjunction with the IMS presentation.

SECOND QUARTER 2025 FINANCIAL RESULTS
Revenue: Total revenue for the second quarter of 2025 was $6.5 million, compared to $12.0 million for the second quarter of 2024. The decrease in revenue was primarily due to an $8.0 million milestone that was earned from Biogen in the second quarter of 2024 partially offset by achievement of a preclinical milestone under our MKDG collaboration and continued progress on our other collaboration programs.
Research and Development (R&D) Expense: R&D expense for the second quarter of 2025 was $26.2 million compared to $23.8 million for the second quarter of 2024. The increase in R&D expense was primarily related to clinical trial expenses for cemsidomide, in addition to increased preclinical spend as the company’s research collaborations continue to advance.
General and Administrative (G&A) Expense: G&A expense for the second quarter of 2025 was $8.8 million compared to $9.7 million for the second quarter of 2024. The decrease was primarily related to lower stock-based compensation expense.
Net Loss and Net Loss per Share: Net loss for the second quarter of 2025 was $26.0 million, compared to $17.7 million for the second quarter of 2024. Net loss per share for the second quarter of 2025 was $0.37 compared to $0.26 for the second quarter of 2024.
Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of June 30, 2025 were $223.0 million, compared to $234.7 million as of March 31, 2025 and $267.3 million as of December 31, 2024. The decrease during the second quarter was primarily the result of cash used to fund operations and advance our programs, partially offset by cash received for milestones under our Roche and MKDG collaborations. The company expects that its cash, cash equivalents and marketable securities as of June 30, 2025 will enable the company to fund its operating plan to mid-2027.
