Clinical Trials

Multiple clinical trials evaluate CBL0137 across diverse oncology indications, including advanced solid tumors, glioblastoma, melanoma, soft tissue sarcoma, and hematological malignancies. Encompassing Early Phase 1, Phase 1, and Phase 1/2 protocols, these studies are sponsored by academic medical centers and industry partners, including Incuron, the Children's Oncology Group, Fox Chase Cancer Center, and Roswell Park Cancer Institute. Recruitment statuses across the portfolio vary, comprising completed, actively recruiting, suspended, and terminated studies.

Compliance for Clinical Use

Mechanism and Biochemical Profile

CBL0137 binds to and inhibits the histone chaperone FACT (facilitates chromatin transcription), which simultaneously suppresses NF-κB activity (EC50 = 0.47 μM) and activates the p53 pathway (EC50 = 0.37 μM) to disrupt vital chromatin dynamics. This targeted biochemical dual-action triggers cellular apoptosis and halts pro-survival signaling, providing a mechanistic rationale for suppressing tumor proliferation in clinical trial settings including advanced solid tumors, glioblastoma, and melanoma.

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.
