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 announced plans to share data from the Phase 1 dose escalation portions of the ongoing Phase 1/2 trials of CFT7455 and CFT8634. The CFT8634 Phase 1 dose escalation data has been accepted as a poster presentation at the Connective Tissue Oncology Society (CTOS) Annual Meeting taking place from November 1 – 4, 2023 in Dublin, Ireland. C4T will host a company-sponsored event on December 12, 2023, to share the CFT7455 dose escalation data in relapsed/refractory multiple myeloma (R/R MM).
Upcoming CFT8634 Clinical Data
The Phase 1/2 trial is designed to characterize safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and evidence of anti-tumor activity of CFT8634 based on RECIST 1.1 criteria. As of August 29, 2023, 32 patients were enrolled across six dose escalation cohorts using a daily dosing schedule.
CTOS Presentation Details
Title: Initial results from a Phase 1 study of CFT8634, a novel bifunctional degradation activating compound (BiDAC) degrader of BRD9, in synovial sarcoma and SMARCB1-null tumors
Format: Poster Presentation
Time: Thursday, November 2, 2023; 5:30 PM – 6:30 PM IST (9:00 AM EST)
Presenter: Mark Agulnik, M.D., sarcoma section chief, department of medical oncology and therapeutics research, City of Hope
Data included in the poster presentation will be PK, PD, safety and RECIST criteria efficacy measures.
Upcoming CFT7455 Clinical Data
The Phase 1/2 trial is designed to characterize the safety, tolerability, PK, PD and anti-tumor activity of CFT7455 in patients with R/R MM or relapsed/refractory non-Hodgkin’s lymphoma (R/R NHL). The Phase 1 dose escalation portion of the ongoing Phase 1/2 trial has utilized a 14 days on/14 days off dosing schedule within which both daily dosing and Monday/Wednesday/Friday dosing were explored. C4T has completed the Phase 1 dose escalation for CFT7455 as a monotherapy in R/R MM using a 14 days on/14 days off dosing schedule; 22 patients were enrolled across five dose escalation cohorts for this portion of the study. Enrollment continues for the Phase 1 dose escalation evaluating CFT7455 with dexamethasone in R/R MM and as a monotherapy in R/R NHL.
At a company-sponsored event on December 12, 2023, C4T plans to present Phase 1 dose escalation data that focuses on the CFT7455 monotherapy regimen in R/R MM.

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).
