Clinical Trials

Eltanexor (KPT-8602), a nuclear export inhibitor, is evaluated in several clinical trials across Phase I and Phase II studies as monotherapy and combination therapy. These trials target hematologic malignancies and advanced solid tumors, including acute myeloid leukemia, myelodysplastic syndromes, relapsed or refractory multiple myeloma, metastatic colorectal cancer, and metastatic castration-resistant prostate cancer. Sponsored by industry, academic, and government entities such as Karyopharm Therapeutics, the National Cancer Institute, and Vanderbilt-Ingram Cancer Center, statuses span recruiting, active not recruiting, completed, and terminated.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Eltanexor is a second-generation, orally bioavailable inhibitor of exportin-1 that selectively binds XPO1 to block the nuclear export of tumor suppressor proteins, leading to nuclear protein accumulation, cell cycle arrest, and apoptosis in malignant cells. This mechanism of nuclear transport inhibition underlies its clinical evaluation for conditions such as acute myeloid leukemia, myelodysplastic syndromes, multiple myeloma, and advanced solid tumors.

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).
