Cemsidomide Phase 1 Trial in Multiple Myeloma and non-Hodgkin’s Lymphoma Continues to Progress through Dose Escalation; Data on Track for Q4 2024

Cash, Cash Equivalents and Marketable Securities of $295.7 million as of June 30, 2024; Expected to Provide Runway into 2027

WATERTOWN, Mass., Aug. 01, 2024 (GLOBE NEWSWIRE) -- C4 Therapeutics, Inc. (C4T) (Nasdaq: CCCC), a clinical-stage biopharmaceutical company dedicated to advancing targeted protein degradation science, reported financial results today for the second quarter ended June 30, 2024, as well as recent business highlights.

“Our strong execution during the first half of the year has built momentum across our clinical, discovery and partnered programs, each of which has the potential to advance targeted protein degradation science and transform patients’ lives,” said Andrew Hirsch, president and chief executive officer of C4 Therapeutics. “Our two lead programs continue to advance in the clinic, and we are on track to share multiple Phase 1 datasets during the second half of the year. At the upcoming ESMO Congress, we will present initial CFT1946 Phase 1 data, marking the first clinical presentation for a BRAF V600X degrader, which has the potential to address many of the liabilities that occur with inhibitors. Additionally, we expect to share updated cemsidomide Phase 1 data in relapsed refractory multiple myeloma and relapsed refractory non-Hodgkin’s lymphoma in the fourth quarter.”

SECOND QUARTER 2024 AND RECENT ACHIEVEMENTS

Cemsidomide: Cemsidomide is an oral degrader of IKZF1/3 for the potential treatment of relapsed/refractory (R/R) multiple myeloma (MM) and R/R non-Hodgkin’s lymphoma (NHL).

• Advanced the Phase 1/2 Clinical Trial. The cemsidomide Phase 1/2 trial in combination with dexamethasone for R/R MM and as a monotherapy for R/R NHL continues to enroll patients. For the combination with dexamethasone MM arm, dose level 4 (75 µg QD) has been declared safe and additional patients are enrolling in this expansion cohort. Dose escalation continues as the maximum tolerated dose has not yet been reached. For the monotherapy NHL arm, patients are enrolling at dose level 5 (100 µg QD).
  

CFT1946: CFT1946 is an oral degrader targeting BRAF V600X mutations for the potential treatment of solid tumors including colorectal cancer (CRC), melanoma and non-small cell lung cancer (NSCLC).

• Advanced the Phase 1/2 Clinical Trial. The CFT1946 Phase 1/2 trial for BRAF V600X mutant solid tumors continues to enroll patients. Enrollment is complete at dose level 5 (640 mg BID), with patients currently in the dose limiting toxicity evaluation period for this dose level. Simultaneously, patients continue to be evaluated for pharmacokinetic, pharmacodynamic and anti-tumor activity at the 160 mg BID and 320 mg BID dose levels. Additionally, patients are now enrolling in a monotherapy exploratory expansion cohort for BRAF inhibitor refractory melanoma at the 320 mg BID dose level.
  
  The Phase 1b portion of the trial evaluating CFT1946 in combination with cetuximab for CRC has also been opened and patients are enrolling at the 160 mg BID dose level.

• Preliminary CFT1946 Monotherapy Data Accepted as a Mini Oral Presentation at the European Society for Medical Oncology (ESMO) Congress 2024. Monotherapy data from the ongoing CFT1946 Phase 1 trial will be presented on Saturday, September 14, 2024 from 2:45 – 2:50 CEST at the ESMO Congress 2024 in Barcelona, Spain.
  

CORPORATE UPDATES:

• In June 2024, Ron Cooper was appointed as chairman of C4T’s Board of Directors as a part of C4T’s commitment to strategically transform the Board to lead the company into its next phase of growth. Mr. Cooper brings decades of deep biopharmaceutical executive leadership across discovery, development and commercialization.

SECOND QUARTER 2024 FINANCIAL RESULTS

Revenue: Total revenue for the second quarter of 2024 was $12.0 million, compared to $2.7 million for the second quarter of 2023. The increase in revenue was primarily due to the receipt of an $8.0 million milestone payment from Biogen after the company accepted delivery of a development candidate. Total revenue for the second quarter of 2024 reflects revenue recognized under our collaborations with Merck KGaA, Darmstadt, Germany (MKDG), Merck, Roche and Biogen, and total revenue recognized in the second quarter of 2023 reflects revenue recognized under collaboration agreements with Roche and Biogen.

Research and Development (R&D) Expense: R&D expense for the second quarter of 2024 was $23.8 million, compared to $29.9 million for the second quarter of 2023. The reduction in R&D expense was primarily due to the prioritization of our internal discovery efforts and stopping clinical development for CFT8634, partially offset by increased clinical trial expense as cemsidomide and CFT1946 continue to advance.

General and Administrative (G&A) Expense: G&A expense was $9.7 million for the second quarter of 2024, compared to $10.3 million for the second quarter of 2023. The decrease in G&A expense was primarily attributable to a reduction in external consulting spend.

Net Loss and Net Loss per Share: Net loss for the second quarter of 2024 was $17.7 million, compared to $35.9 million for the second quarter of 2023. Net loss per share for the second quarter of 2024 was $0.26 compared to $0.73 for the second quarter of 2023.

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of June 30, 2024 were $295.7 million, compared to $299.2 million as of March 31, 2024, and $281.7 million as of December 31, 2023. The reduction in cash, cash equivalents and marketable securities during the second quarter was primarily the result of operating expenses offset by receipt of the upfront payment from our collaborator MKDG and a milestone payment from Biogen. C4T expects that its cash, cash equivalents and marketable securities as of June 30, 2024 will be sufficient to fund planned operating expenses and capital expenditures into 2027.
