Business Overview and History

C4 Therapeutics, Inc. (CCCC) is a clinical-stage biopharmaceutical company dedicated to advancing the science of targeted protein degradation to create a new generation of medicines that can transform patients' lives. The company's proprietary TORPEDO platform enables it to efficiently design and optimize small molecule protein degraders that harness the body's natural process for destroying unwanted proteins, offering the potential to overcome drug resistance, target "undruggable" proteins, and improve patient outcomes.

C4 Therapeutics was incorporated in October 2015 under the laws of the State of Delaware. The company's early years were focused on performing research and development, building its intellectual property portfolio, recruiting personnel, and raising capital to support these activities. Since its inception, C4 Therapeutics has funded its operations primarily through sales of equity interests, including public offerings of its common stock, as well as proceeds from collaboration agreements and debt financing.

The company has made significant strides in advancing its pipeline and forming strategic partnerships. In 2016, C4 Therapeutics entered into a license agreement with Roche to collaborate on the research, development, manufacture, and commercialization of target-binding degrader medicines. This was followed by a collaboration research and license agreement with Biogen in 2018, which expanded the company's research activities into neurodegenerative diseases. These collaborations have provided C4 Therapeutics with valuable research funding and the potential for future milestone and royalty payments.

A major milestone for the company came in 2021 when it initiated its first-in-human Phase 1 clinical trials for its lead product candidates, cemsidomide and CFT1946. However, the path of drug development is not without challenges. In 2022, C4 Therapeutics made the difficult decision to shut down a clinical trial evaluating one of its other product candidates, CFT8634, after determining that the program did not meet the company's criteria for continued investment.

Despite these challenges and the company's early-stage status, C4 Therapeutics has continued to make progress in advancing its pipeline. The company's lead product candidate, cemsidomide, is an orally bioavailable MonoDAC degrader targeting the IKZF1 and IKZF3 proteins, which play a central role in multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL). Cemsidomide is currently in a Phase 1/2 clinical trial, with data presentations at the 2024 American Society of Hematology (ASH) Annual Meeting demonstrating a well-tolerated safety profile and compelling anti-tumor activity across both the MM and NHL patient populations.

The company's next most advanced program is CFT1946, an orally bioavailable BiDAC degrader designed to selectively degrade BRAF V600 mutant proteins in solid tumors such as melanoma and colorectal cancer (CRC). CFT1946 has shown the ability to cross the blood-brain barrier in preclinical studies, an important feature given the high incidence of brain metastases in BRAF V600 mutant cancers. Initial Phase 1 data for CFT1946 presented in 2024 demonstrated a well-tolerated safety profile and early signs of anti-tumor activity.

In addition to its lead programs, C4 Therapeutics is advancing several other degrader candidates, including CFT8919, an orally bioavailable, allosteric, mutant-selective degrader of EGFR L858R for non-small cell lung cancer (NSCLC). The company has also established strategic collaborations with partners such as Merck, MKDG, and Betta Pharmaceuticals to further expand the reach of its TORPEDO platform and pipeline.

Financial Overview

As of December 31, 2024, C4 Therapeutics reported cash, cash equivalents, and marketable securities of $267.3 million, which the company believes will be sufficient to fund its operations into 2027. For the year ended December 31, 2024, the company reported total revenue of $35.6 million, a 71% increase compared to the prior year, driven by milestone payments and research funding from its collaboration agreements.

However, C4 Therapeutics continues to invest heavily in its research and development efforts, with R&D expenses of $110.6 million in 2024, compared to $117.7 million in 2023. The company reported a net loss of $105.3 million in 2024, an improvement from the $132.5 million net loss in 2023. C4 Therapeutics' strong cash position and commitment to advancing its pipeline suggest it is well-positioned to execute on its strategic priorities in the coming years.

The increase in revenue for 2024 was primarily driven by a $14.7 million increase in revenue recognized from the MKDG, Merck, and Betta Pharma collaborations that commenced activities in 2024, as well as a $6.3 million increase in revenue from the Biogen agreement. These increases were partially offset by a $5.1 million decrease in revenue from the Roche agreement and a $1.1 million decrease in revenue from the Calico agreement.

In the most recent quarter (Q4 2024), C4 Therapeutics reported revenue of $5.2 million, down 39.5% year-over-year. The decrease in revenue was primarily due to lower collaboration revenue recognized in the quarter compared to the prior year period. The net loss for Q4 2024 was $34.6 million.

Liquidity

C4 Therapeutics' liquidity position remains strong, with $267.3 million in cash, cash equivalents, and marketable securities as of December 31, 2024. This robust cash position provides the company with a runway into 2027, allowing it to continue advancing its pipeline and pursuing its strategic objectives without immediate concerns about funding constraints.

The company's debt-to-equity ratio stands at 0.30, indicating a relatively low level of debt compared to equity. C4 Therapeutics has $55.5 million in cash and cash equivalents, and both its current ratio and quick ratio are 5.71, suggesting a strong ability to meet short-term obligations.

Research and Development

C4 Therapeutics' research and development expenses were $110.6 million in 2024, down from $117.7 million in the prior year. This decrease was primarily due to a $6 million reduction in personnel expenses as a result of restructuring activities, a $1.9 million decrease in professional fees, and a $1.2 million decrease in facilities and supply expenses. These decreases were partially offset by a $1.6 million increase in clinical expenses due to continued progress on the cemsidomide and CFT1946 programs.

The company's pipeline continues to advance, with promising data from its lead candidates. In December 2024, C4 Therapeutics presented data from the ongoing Phase 1/2 trial of cemsidomide in combination with dexamethasone for multiple myeloma, demonstrating a well-tolerated safety profile and compelling anti-myeloma activity across a broad range of doses. The data also showed that neutropenia was manageable, and no cases resulted in cemsidomide discontinuation. In non-Hodgkin lymphoma, cemsidomide demonstrated compelling anti-lymphoma activity as a monotherapy across a broad range of doses in peripheral T-cell lymphoma patients.

For CFT1946, the company presented monotherapy data from the ongoing Phase 1/2 trial in September 2024, which demonstrated that the candidate was well-tolerated with initial signs of anti-tumor activity across all dose levels. This data supports the continued development of CFT1946 for the treatment of BRAF V600 mutant solid tumors.

Strategic Partnerships

C4 Therapeutics has established several strategic partnerships to expand the reach of its TORPEDO platform and pipeline. In May 2023, the company entered into a license and collaboration agreement with Betta Pharma to collaborate on the development and commercialization of CFT8919 in Greater China, with C4 Therapeutics retaining rights to develop and commercialize the candidate in the rest of the world.
