WATERTOWN, Mass., May 04, 2023 (GLOBE NEWSWIRE) -- C4 Therapeutics, Inc. (C4T) (Nasdaq: CCCC), a clinical-stage biopharmaceutical company dedicated to advancing targeted protein degradation science to develop a new generation of small-molecule medicines and transform how disease is treated, today reported financial results for the first quarter ended March 31, 2023, as well as recent business highlights.

“Thus far in 2023, we have executed against key milestones, including progressing three orally bioavailable degrader programs through the clinic and presented new preclinical data from our most recent clinical program, CFT1946, at AACR,” said Andrew Hirsch, president and chief executive officer of C4 Therapeutics. “This preclinical data highlights the capabilities of our TORPEDO^® platform to develop catalytically efficient and orally bioavailable degraders and we look forward to continuing to advance both MonoDAC and BiDAC clinical programs to bring new therapeutic options to patients with difficult-to-treat diseases.”

FIRST QUARTER 2023 AND RECENT HIGHLIGHTS

CFT7455: CFT7455 is an oral degrader of IKZF1/3 for the treatment of multiple myeloma (MM) and non-Hodgkin’s lymphomas (NHL).

• Progressed the Phase 1/2 Clinical Trial: The dose escalation portion of the CFT7455 Phase 1/2 clinical trial continues in MM and NHL. The three arms of the trial are evaluating CFT7455 as a monotherapy for MM, in combination with dexamethasone for MM and as a monotherapy for NHL.
  

CFT8634: CFT8634 is an oral degrader of BRD9 for the treatment of synovial sarcoma and SMARCB1-null solid tumors.

• Encouraging Initial Pharmacokinetic (PK) and Pharmacodynamic (PD) Data: In January 2023, shared PK and PD data from the initial escalation cohorts of the ongoing CFT8634 Phase 1/2 clinical trial demonstrating dose proportional exposure, strong oral bioavailability and deep BRD9 degradation.
• Progressed the Phase 1/2 Clinical Trial: The dose escalation portion of the CFT8634 Phase 1/2 clinical trial continues in synovial sarcoma and SMARCB1-null solid tumors.

CFT1946: CFT1946 is an oral degrader targeting BRAF V600 mutations for the treatment of solid tumors including non-small cell lung cancer (NSCLC), colorectal cancer (CRC) and melanoma.

• Dosed First Patient in Phase 1/2 Clinical Trial: The CFT1946 Phase 1/2 clinical trial was initiated in January. Five trial sites are now open and enrolling patients with BRAF V600 solid tumors, including NSCLC, CRC and melanoma.
• Presented New Preclinical Data at AACR: In April 2023, C4T presented new preclinical data on the discovery and characterization of CFT1946 at the American Association for Cancer Research 2023 Annual Meeting. The preclinical data demonstrated that CFT1946 is a potent and mutant-selective BiDAC degrader of BRAF V600 and is superior to inhibitors in in vitro and in vivo models with BRAF V600E driven disease and in the escape mutant BRAF V600E/NRAS-Q61K-driven model. The data further demonstrate C4T’s medicinal chemistry abilities to access catalytically efficient and orally bioavailable degraders by combining C4T’s cereblon toolkit with rational ligand and linker modifications.

KEY UPCOMING MILESTONES

• CFT7455: Present Phase 1 dose escalation data from the Phase 1/2 clinical trial of Arm B1, evaluating CFT7455 as a monotherapy in MM, in the second half of 2023.
• CFT8634: Present Phase 1 dose escalation data from the Phase 1/2 clinical trial for synovial sarcoma and SMARCB1-null solid tumors in the second half of 2023.
• CFT1946: Present a Trial in Progress poster at the 2023 American Society of Clinical Oncology Annual Meeting on June 3, 2023 at 8:00 AM CST, titled “A Phase 1/2 Study of CFT1946, A Novel Bifunctional Degradation Activating Compound, or BiDAC Degrader, of Mutant BRAF V600 as Monotherapy and in Combination with Trametinib, in Mutant BRAF V600 Solid Tumors.”
• CFT8919: Submit an Investigational New Drug (IND) application for CFT8919 for the treatment of NSCLC in the first half of 2023.

UPCOMING INVESTOR EVENTS

• June 7, 2023: Management will participate in the Jefferies Global Healthcare Conference in New York.
  

FIRST QUARTER 2023 FINANCIAL RESULTS

Revenue: Total revenue for the first quarter of 2023 was $3.8 million, compared to $7.7 million for the first quarter of 2022. Total revenue reflects revenue recognized under collaboration agreements with Roche, Biogen and Calico.

Research and Development (R&D) Expense: R&D expense for the first quarter of 2023 was $29.0 million, compared to $26.2 million for the first quarter of 2022. The increase in R&D expense was primarily attributable to increased clinical expenses from the ongoing CFT7455, CFT8634 and CFT1946 Phase 1/2 clinical trials.

General and Administrative (G&A) Expense: G&A expense for the first quarter of 2023 was $10.9 million, compared to $12.8 million for the first quarter of 2022. The decrease in G&A expense was primarily attributable to decreased professional fees and stock compensation expense compared to 2022.

Net Loss and Net Loss per Share: Net loss for the first quarter of 2023 was $34.8 million, compared to $31.6 million for the first quarter of 2022. Net loss per share for the first quarter of 2023 was $0.71 compared to $0.65 for the first quarter of 2022.

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of March 31, 2023, were $305.0 million, compared to $337.1 million as of December 31, 2022. The decrease in cash was primarily driven by expenditures to fund operations. C4T expects that its cash, cash equivalents and marketable securities as of March 31, 2023, along with cost savings, will be sufficient to fund planned operating expenses and capital expenditures into 2025.

About CFT7455

CFT7455 is an orally bioavailable MonoDAC™ degrader designed to be highly potent and selective against its intended targets of Ikaros (IKZF1) and Aiolos (IKZF3). CFT7455 binds with high affinity to the E3 ligase adapter protein, cereblon, to target and degrade IKZF1/3 for the treatment of multiple myeloma and non-Hodgkin's lymphomas, including peripheral T cell lymphoma and mantle cell lymphoma. In early clinical data, CFT7455 demonstrated deep and durable degradation of IKZF1/3. C4T is enrolling patients in its ongoing Phase 1/2 clinical trial of CFT7455. More information about this trial may be accessed at www.clinicaltrials.gov (identifier: NCT04756726).

About CFT8634

CFT8634 is an orally bioavailable BiDAC™ degrader designed to be potent and selective against BRD9. BRD9 was previously considered an undruggable target due to the inability of bromodomain inhibitors to effectively treat cancers dependent on BRD9. Unlike BRD9 inhibition, BRD9 degradation has been shown to be efficacious in pre-clinical models of synovial sarcoma. C4T is enrolling patients in its ongoing Phase 1/2 clinical trial of CFT8634 for the treatment of synovial sarcoma and SMARCB1-null solid tumors. More information about this trial may be accessed at www.clinicaltrials.gov (identifier: NCT05355753).

About CFT1946

CFT1946 is an orally bioavailable BiDAC™ degrader designed to be potent and selective against BRAF V600 mutant targets. In preclinical studies, CFT1946 is active in vivo and in vitro in models with BRAF V600E driven disease and in models resistant to BRAF inhibitors. C4T is advancing CFT1946 to the clinic to study treatment for BRAF V600 mutant solid tumors including non-small cell lung cancer, colorectal cancer, and melanoma. C4T is enrolling patients in its ongoing Phase 1/2 clinical trial of CFT1946. More information about this trial may be accessed at www.clinicaltrials.gov (identifier: NCT05668585).
