The Effect of Kinisoquin™ on Thromboembolic Events in Patients With Metastatic or Locally Advanced Pancreatic Cancer

A Randomized, Placebo-Controlled, Double-Blind Phase 3 Trial Comparing, Relative to Placebo, the Effect of Kinisoquin™ on Thromboembolic Events in Patients With Metastatic or Locally Advanced Pancreatic Cancer (CATIQ P3)

The aim of this Phase 3 study is to evaluate the efficacy of Kinisoquin™ as compared to the placebo in prevention of thromboembolic events in patients with metastatic or locally advanced pancreatic cancer.

Approximately one-third of all pancreatic cancer patients suffer from a venous thromboembolism (VTE). The greatest risk of thrombosis is observed in the first three months following the start of chemotherapy. The development of distant metastasis in pancreatic cancer increases the risk of VTE approximately 4-fold.

Kinisoquin™ is a more bioavailable form of quercetin, a naturally occurring flavonol, intended to prevent thromboembolic events in cancer patients. The aim of this study is to evaluate the efficacy of Kinisoquin™ in prevention of thromboembolic events in patients with metastatic or locally advanced pancreatic cancer.

This trial is a randomized, placebo-controlled, double-blinded, Phase 3 trial in metastatic or locally advanced pancreatic cancer patients who are initiating chemotherapy.

Inclusion Criteria:

1. Participants must have histological or cytological confirmed pancreatic adenocarcinoma malignancy that is metastatic (including recurrent with distant metastases) or locally advanced.

2. Receiving first line chemotherapy (within 45 days of first dose of study drug) Note: subjects must be either initiating first systemic cancer therapy regimen following initial diagnosis or initiating first cycle of chemotherapy for disease recurrence.

3. Minimum age 18 years.

4. Life expectancy of greater than 4 months.

5. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.

6. Participants must have preserved organ and marrow function as defined by:

   • Platelet count ≥ 100,000/mcL.
   • Prothrombin time (PT) and partial thromboplastin time (PTT) ≤ 1.5x institutional upper limit of normal (ULN).
   • Total bilirubin ≤ 3x ULN without liver metastases and < 5x ULN in presence of liver metastases.
   • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3x ULN without liver metastases and < 5x ULN in the presence of liver metastases
   • Estimated creatinine clearance (CrCl > 30 mL/min).

7. Willingness of women of child-bearing potential and men to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation until at least 4 weeks after study completion.

8. Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

1. Participants with known brain metastases
2. Prior history of documented thromboembolic event within the last 12 months (excluding central line associated events whereby patients completed anticoagulation)
3. Active bleeding or high risk for bleeding (e.g. known acute gastrointestinal ulcer)
4. History of significant hemorrhage (requiring hospitalization or transfusion) outside of a surgical setting within the last 24 months
5. Familial bleeding diathesis
6. Known diagnosis of disseminated intravascular coagulation (DIC)
7. Currently receiving anticoagulant therapy
8. Current daily use of aspirin (> 100mg daily), 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 > 800mg daily or equivalent)
9. 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
10. Known intolerance to the active ingredient of Kinisoquin™, isoquercetin, nicotinic acid, or ascorbic acid (including known G6PD deficiency)
11. Females of child-bearing potential who are lactating, have a positive pregnancy test at Screening, or are unwilling to use acceptable contraception prior to study entry and for the duration of study participation until at least 4 weeks after study completion.
12. Participation in other clinical trials The study is open to any individual who has a metastatic or locally advanced pancreatic adenocarcinoma malignancy without discrimination based on race, religion, political affiliation, or other criteria.
