A Study of Isoquercetin in People With Ovarian Cancer

Exclusion Criteria11

• Prior history of documented venous thromboembolic event within the last 2 years (excluding central line associated events whereby patients completed anticoagulation)
• Active bleeding or high risk for bleeding (e.g., known acute gastrointestinal ulcer)
• History of significant hemorrhage (requiring hospitalization or transfusion) outside of a surgical setting within the last 24 months
• Familial bleeding diathesis
• Known diagnosis of disseminated intravascular coagulation (DIC)
• Currently receiving anticoagulant therapy
• Current daily use of aspirin, clopidogrel (Plavix), cilostazol (Pletal), aspirin-dipyridamole (Aggrenox) (within 10 days) or considered to use regular use of higher doses of non-steroidal anti-inflammatory agents as determined by the treating physician (e.g ibuprofen \> 800 mg daily or equivalent)
• Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Known intolerance of (iso)quercetin, niacin or ascorbic acid (including known G6PD deficiency).
• Participants with known brain metastases
• Pregnant women are excluded from this study because isoquercetin is a PDI inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with isoquercetin, breastfeeding should be discontinued if the mother is treated with isoquercetin.
