Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Participants must meet the following criteria on screening examination to be eligible to participate in phase 2 and 3 of the study:
  • Participants must have histologically confirmed malignancy that is metastatic or currently unresectable.
  • Eligible malignancies include:
  • Adenocarcinoma of the pancreas (currently unresectable or metastatic)
  • Colorectal (stage IV)
  • Non-small cell lung cancer (currently unresectable stage III or stage IV)
Show all 19Show fewer
  • Receiving or scheduled to receive first or second line chemotherapy (within 30 days of registration)
  • Minimum age 18 years. Because limited dosing or adverse event data are currently available on the use of isoquercetin in participants <18 years of age, children are excluded from this study but will be eligible for future pediatric isoquercetin trials.
  • Life expectancy of greater than 4 months.
  • ECOG performance status ≤2 (see Appendix B ).
  • Patient must be able to swallow capsules (phase III only)
  • Participants must have preserved organ and marrow function as defined below:
  • Absolute neutrophil count ≥1,000/mcL
  • Platelets ≥ 90,000/mcL
  • PT and PTT ≤ 1.5 x upper limit of normal
  • Total bilirubin < 2.0 mg/dl
  • AST (SGOT)/ALT (SGPT) ≤ 2.5 X institutional upper limit of normal Creatinine < 2.0 mg/dl
  • The effects of isoquercetin on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent document.

Who cannot join

  • Participants may not be receiving any other study agents.
  • Participants with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
  • 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
Show all 12Show fewer
  • Known diagnosis of disseminated intravascular coagulation (DIC)
  • Currently receiving anticoagulant therapy
  • Current daily use of aspirin (>81mg 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 > 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 niacin or ascorbic acid (including known G6PD deficiency)
  • 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. These potential risks may also apply to other agents used in this study.

About this study

Official title: Randomized, Placebo-controlled, Double-blind Phase II/III Trial of Oral Isoquercetin to Prevent Venous Thromboembolic Events in Cancer Patients.

This research study is evaluating a drug called isoquercetin to prevent venous thrombosis (blood clots), in participants who have pancreas, non small cell lung cancer or colorectal cancer.

Read the detailed description
  • This research study is a Phase II/III clinical trial. --The goal of this trial is to evaluate if isoquercetin can prevent blood clots in patients with pancreas, non small cell lung cancer or colorectal cancer. In the Phase II part of this study, the investigators are looking for the dose of isoquercetin to reduce D-dimer and demonstrate safety.
  • Phase III Endpoint and Treatment Plan
  • Primary Endpoint for Phase III portion of protocol: Cumulative incidence of VTE.
  • Following the completion of the phase II portion, enrolled patients will be randomized 1:1 to Arm C (isoquercetin) or Arm D (placebo). The dose for Arm C will be determined after evaluation of the Phase II portion of the trial. The protocol will be amended when the decision is made whether to proceed to Phase III and what dose to use for Arm C. The study will be double-blinded to treatment arm. Lower extremity ultrasound will be performed at 56 days. Baseline D-dimer and correlative labs will be drawn at Day 1 and at 56 days. Patients will be followed for survival after completion of 56 days.
  • At BIDMC, optional blood draw will be performed at time 0 and 4 hours following the first dose of study drug.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change in D-dimer Value

    D-dimer concentrations will be compared for each patient at day 0 and day 56 by a paired-t test analysis. Analysis will be performed on an intention to treat basis for patients who undergo randomization and completed the baseline and day 56 D-dimer assessments.

    Measured: Baseline, 56 Day

Secondary outcomes (2)
  1. Number of Participants With Hemorrhage

    Investigating the safety of isoquercetin in cancer patients

    Measured: study visits until day 56

  2. Cumulative Incidence of VTE at 56 Days

    To investigate the cumulative incidence of VTE according to tissue factor bearing microparticle status (and isoquercetin randomization).

    Measured: 56 days

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Isoquercetin in people with Thromboembolism of Vein VTE in Colorectal Cancer and Thromboembolism of Vein in Pancreatic Cancer, run by Jeffrey Zwicker, MD at 11 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Nov 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change in D-dimer Value (time frame: Baseline, 56 Day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02195232, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2021.
