Isoquercetin dosing and patient profiling to lower clot risk in cancer

Isoquercetin as a PDI inhibitor: dose-optimization and patient phenotyping

NIH-funded research Sloan-Kettering Inst Can Research · NIH-11319724

This work looks at different doses of the plant compound isoquercetin to reduce dangerous blood clots in people with advanced cancer and to find which patients benefit most.

What this research studies

If you join, you would receive isoquercetin at one of several dosing schedules while doctors monitor blood tests and safety measures. The team will measure clot-related markers like D-dimer and collect detailed health and tumor information to profile participants. Researchers will use pharmacodynamic modeling and these patient data to pick the best dose and identify characteristics linked to benefit. Findings will guide a later, larger trial and aim to reduce clot risk without increasing bleeding.

Who could benefit from this research

Good fit: Adults with advanced cancer who are at high risk for venous thromboembolism and meet the study's eligibility and safety criteria are the intended participants.

Not a fit: People without cancer, those not at elevated clot risk, or patients with active bleeding or very high bleeding risk are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, this could provide a better-tolerated way to lower venous clot risk in people with cancer without increasing bleeding.

How similar studies have performed: A prior phase 2 trial showed a significant drop in circulating D-dimer consistent with antithrombotic activity and extensive preclinical work supports the approach, but optimal dosing has not yet been established.
