Clinical Trials

CFT7455 is currently being evaluated in several clinical trials sponsored by C4 Therapeutics, Inc., focusing on hematologic malignancies, specifically relapsed or refractory multiple myeloma and non-Hodgkin's lymphoma. These early-phase evaluations include Phase 1 and Phase 1/2 studies designed to characterize the drug's safety, tolerability, and preliminary therapeutic activity. Recruitment across these trials includes both actively recruiting cohorts and active, non-recruiting trial arms.

Compliance for Clinical Use

Mechanism and Biochemical Profile

CFT7455 binds with high affinity (Kd = 0.9 nM) to the cereblon E3 ligase complex, thereby directing the zinc finger transcription factors IKZF1 (Ikaros) and IKZF3 (Aiolos) toward ubiquitin-mediated proteasomal degradation. This targeted depletion disrupts essential downstream oncogenic gene expression and survival signaling in malignant lymphocytes, resulting in impaired cell proliferation and promoting tumor regression in multiple myeloma and non-Hodgkin's lymphoma.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).
