THIRD QUARTER 2022 FINANCIAL RESULTS

Revenue: Total revenue for the third quarter of 2022 was $6.8 million, compared to $8.5 million for the third quarter of 2021. Total revenue reflects revenue recognized under collaboration agreements with Roche, Biogen, and Calico.

Research and Development (R&D) Expense: R&D expense for the third quarter of 2022 was $29.7 million, compared to $24.3 million for the third quarter of 2021. The increase in R&D expense was primarily attributable to increased personnel expenses, and clinical expenses from the ongoing CFT7455 and CFT8634 Phase 1/2 clinical trials. 

General and Administrative (G&A) Expense: G&A expense for the third quarter of 2022 was $9.6 million, compared to $8.5 million for the third quarter of 2021. The increase in G&A expense was primarily attributable to increased personnel expenses.

Net Loss and Net Loss per Share: Net loss for the third quarter of 2022 was $32.0 million, compared to $24.7 million for the third quarter of 2021. Net loss per share for the third quarter of 2022 was $0.65, compared to $0.51 for the third quarter of 2021. 

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of September 30, 2022, were $366.0 million, compared to $451.5 million as of December 31, 2021. The decrease in cash was primarily driven by expenditures to fund operations. C4T expects that its cash, cash equivalents and marketable securities as of September 30, 2022, together with future payments expected to be received under existing collaboration agreements, will be sufficient to fund planned operating expenses and capital expenditures to the end of 2024.

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 has been 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 pre-clinical 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. In September 2022, C4T achieved investigational new drug application clearance from the U.S. FDA for our Phase 1/2 clinical trial of CFT1946.
