Abstract

The present invention relates to methods for reducing soluble P-selectin and major thrombotic events in cancer patients.

Claims (18)

1. A method for reducing or preventing formation of a thrombus in a patient with cancer at increased risk for bleeding, with an elevated level of soluble P-selectin when compared to a reference or baseline level of soluble P-selectin, comprising administering to the patient a composition comprising an effective amount of isoquercetin, vitamin B3, and vitamin C, the effective amount of isoquercetin being about 500 mg per day,

comprising administrating the composition to the patient for a period of at least about 2 months;

wherein the patient does not exhibit primary venous thromboembolism after administration of the composition.

2. The method of claim 1 , wherein soluble P-selectin is decreased at least about 30% when compared to a reference or baseline level of soluble P-selectin, following administration of the isoquercetin.

3. The method of claim 1 , wherein soluble P-selectin decrease ranges from 30-40%, 40-50%, 55-60%, 60-70%, 70-75%, or 75-80% when compared to a reference or baseline level of soluble P-selectin, following administration of the isoquercetin.

4. The method of claim 1 , wherein the cancer is metastatic cancer.

5. The method of claim 4 , wherein the metastatic cancer is colorectal cancer, pancreatic cancer, or non-small cell lung cancer.

6. The method of claim 4 , wherein the metastatic cancer is selected from the group consisting of metastasizing forms of Hodgkin lymphoma, colorectal cancer, cervical cancer, lung cancer, skin cancer such as squamous cell cancer or basal cell carcinoma, head and neck cancer, gastric cancer, and pancreatic cancer.

7. The method of claim 1 , wherein the cancer is selected from the group consisting of estrogen receptor-dependent breast cancer, estrogen receptor-independent breast cancer, hormone receptor-dependent prostate cancer, hormone receptor-independent prostate cancer, brain cancer, renal cancer, glioblastoma, colon cancer, familial adenomatous polyposis (FAP), colorectal cancer, pancreatic cancer, bladder cancer, esophageal cancer, stomach cancer, genitourinary cancer, gastrointestinal cancer, uterine cancer, ovarian cancer, astrocytomas, gliomas, skin cancer, squamous cell carcinoma, Keratoakantoma, Bowen disease, cutaneous T-Cell Lymphoma, melanoma, basal cell carcinoma, actinic keratosis; ichtiosis; acne, acne vulgaris, sarcomas, Kaposi's sarcoma, osteosarcoma, head and neck cancer, small cell lung carcinoma, non-small cell lung carcinoma, leukemia, lymphomas and other blood cell cancers.

8. The method of claim 1 , wherein the patient exhibits no severe adverse events (grade 3 or 4 toxicities) during treatment.

9. The method of claim 1 , wherein the patient exhibits no primary venous thromboembolism (VTE) during treatment.

10. The method of claim 9 , wherein the patient exhibits no VTE for at least 30-60 days following treatment.

11. The method of claim 1 , wherein the patient exhibits no major hemorrhages during treatment.

12. The method of claim 1 , wherein the patient exhibits a decrease in platelet-dependent thrombin generation of from about 30-60% when compared to a reference or baseline level of platelet dependent thrombin, following administration of the isoquercetin.

13. The method of claim 1 , wherein the patient exhibits decreased D-dimer plasma concentration of about 20-30% when compared to a reference or baseline level of D-dimer plasma concentration, following administration of the isoquercetin.

14. The method of claim 1 , wherein the isoquercetin is administered in a composition comprising about 20 micrograms to about 3 grams of Vitamin B3, and optionally further comprises about 200 micrograms to about 3 grams of Vitamin C.

15. The method of claim 1 , further comprising administering between about 1000 micrograms to about 3000 micrograms of folic acid.

16. The method of claim 1 , wherein the patient exhibits increased PDI inhibition when compared to a reference or baseline level of PDI inhibition, following administration of isoquercetin.
