WATERTOWN, Mass., Nov. 12, 2020 (GLOBE NEWSWIRE) – C4 Therapeutics, Inc. (C4T) (Nasdaq: CCCC), a biopharmaceutical company pioneering a new class of small-molecule drugs that selectively destroys disease-causing proteins through degradation, today reported financial results for the third quarter ended September 30, 2020, highlighted recent progress and provided a business update.

“C4T’s recent IPO was a tremendous milestone for our team and an important accomplishment as the company advances our programs to the clinic. With a strong balance sheet and expanded senior team, we are well-positioned to execute against our pipeline and continue investing in our differentiated TORPEDO^TM discovery platform,” said Andrew Hirsch, chief executive officer at C4 Therapeutics. “Looking ahead, we expect to have four clinical-stage programs by the end of 2022, including our lead candidate, CFT7455, for hematological malignancies, which is on track for an IND submission by the end of this year. We believe targeted protein degraders represent a novel class of medicines with distinctive benefits over traditional inhibitor drugs and look forward to exploring their potential in patients.”

THIRD QUARTER 2020 AND RECENT HIGHLIGHTS

• Amended the Amended and Restated Roche Collaboration Agreement: In November 2020, C4T entered into the First Amendment to its 2018 Amended and Restated License Agreement with F. Hoffman-La Roche Ltd and Hoffman-La Roche Inc., which clarifies the rights and responsibilities of both parties in the event of a program termination. In addition, through this amendment, C4T and Roche mutually agreed to terminate the Amended and Restated Agreement with respect to the target epidermal growth factor receptor (EGFR). With this termination, C4T regains the right to pursue the target EGFR in products that use degradation as their mode of action.

• Presented at Scientific Conferences on Protein Structure and Degradation: In October 2020, C4T participated in the 3^rd Annual Targeted Protein Degradation Summit. Rhamy Zeid, Ph.D., Director of Target Biology at C4T, delivered a presentation highlighting CFT8634, a novel degrader of the protein BRD9. This case study showcased C4T’s TORPEDO platform’s capabilities to enable the development of novel, selective, orally bioavailable degraders. C4T’s Chief Scientific Officer, Stewart Fisher, Ph.D., also led a roundtable discussion on the pace of innovation in drug discovery and development. In November 2020, C4T participated in the 28^th Annual Protein Structure Determination in Industry (PSDI) Conference. Joe Patel, Ph.D., C4T’s Senior Director of Biochemistry, Biophysics and Crystallography, delivered a presentation demonstrating how C4T’s TORPEDO platform leverages HDX data and computational methods to design novel degrader candidates with predictable ternary complexes.

• Completed Upsized Initial Public Offering: In October 2020, C4T completed an upsized initial public offering of 11.0 million shares of common stock, including the full exercise of the underwriters’ over-allotment option, at a price of $19.00 per share. Net proceeds from the offering were $191.1 million.

C4T anticipates initiating a Phase 1/2 clinical trial for this program in 1H 2021.

• IND submission expected in 2H 2021 for CFT8634, an orally bioavailable BiDAC^™ (Bifunctional Degradation Activating Compound) targeting BRD9 for the treatment of synovial sarcoma and SMARCB1-deleted solid tumors. C4T anticipates initiating a Phase 1/2 clinical trial for this program by 2H 2021.

THIRD QUARTER 2020 FINANCIAL RESULTS

Revenues: Total revenues for the third quarter of 2020 were $8.4 million, compared to $5.4 million for the third quarter of 2019. Total revenues reflect revenues recognized under our collaboration agreements with Roche, Biogen and Calico and increased by $3 million compared to the same period of 2019 primarily due to increased reimbursements from Biogen reflecting increase activities on collaboration projects and related activities.

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2020 were $23.9 million, compared to $12.9 million for the third quarter of 2019. The increase in R&D expense was primarily attributable to increased third-party chemistry and biology costs, higher preclinical costs related to our lead programs and increased workforce expenses to support our growing clinical development activities.

General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2020 were $2.9 million, compared to $2.4 million for the third quarter of 2019. The increase in G&A expense was primarily attributable to higher legal and professional costs supporting the company’s growth.

Net Loss: Net loss for the third quarter of 2020 was $21.8 million, compared to $10.1 million for the third quarter of 2019.

Cash Position and Financial Guidance: Cash, cash equivalents and short-term investments as of September 30, 2020, were $199.4 million, compared to $90.5 million as of December 31, 2019. The September 30th balance does not include $191.1 million in net proceeds from our initial public offering, which was completed on October 6, 2020. We expect our cash, cash equivalents and short-term investments, including the net proceeds from our initial public offering and payments to be received under our existing collaboration agreements, will be sufficient to fund planned operating expenses and capital expenditures into the second half of 2023.
