A Biological Study of Resveratrol's Effects on Notch-1 Signaling in Subjects With Low Grade Gastrointestinal Tumors

November 14, 2019 updated by: University of Wisconsin, Madison
Resveratrol has been shown to activate a protein called Notch-1. Signaling of Notch-1 has been shown to prevent tumor cell growth. Resveratrol has also been shown to prevent growth of tumors in mice. The purpose of this study is to examine the effects of resveratrol and Notch-1 on neuroendocrine tumor tissue and to examine how people with neuroendocrine tumors who take resveratrol for up to three months tolerate the product.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will be treated with a dose of 5 gm/day of resveratrol orally, in two divided doses of 2.5 gm each without a break in therapy for a total of three cycles. All patients who receive at least one dose of resveratrol will be evaluated for toxicity and tolerability. Toxicities will be assessed every 28 days while the study drug is being taken by the patient. Pill bottles will be reviewed at this visit as well to ensure compliance with the study medication. Toxicities will be graded according to the NCI Common Toxicity Criteria. Blood will be drawn for a complete blood count and comprehensive metabolic panel. In addition, one vial of serum will be stored at the time of each toxicity assessment for later analysis of resveratrol levels. This level must be drawn one hour after the morning dose and the participants will be instructed to alter the time of the morning dose so as to allow proper timing with the scheduled blood draw.

During the third cycle of treatment, a post-treatment biopsy will be obtained for study related purposes and will be processed only for research related purposes.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. ECOG performance status of 0-2
  2. Age >18 years old
  3. Women who are not postmenopausal must have a negative enrollment blood test and agree to use an effective mode of contraception while taking the study medication
  4. Greater than four weeks must have elapsed since any previous therapy was administered for the neuroendocrine tumor, including surgery, radiation, chemotherapy or local liver therapy.
  5. Octreotide use is allowed but must be initiated at least four weeks prior to enrollment and to the pre-treatment biopsy
  6. Able to give informed consent and willing to undergo the post-treatment research biopsy
  7. Must be able to take oral medications and be without GI tract obstructive symptoms
  8. Subjects with another malignancy for which they are either undergoing treatment with chemotherapy or radiation, or with a malignancy for which such treatments have been recommended, would be excluded or withdrawn from the study.
  9. Must agree to abstain from excessive alcohol, as defined by greater than the equivalent of three glasses of wine per day or one six pack of beer per day

Exclusion Criteria:

1. The principal investigator will review each subject's current medications prior to enrollment of the study to ensure that the administration of Resveratrol will not affect their current medications.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Notch1 activation in post-treatment tumor biopsy specimens when compared to pretreatment levels
Time Frame: 1 year

1. The investigators aim primarily to show that resveratrol therapy in patients with low-grade GI neuroendocrine tumors will significantly increase Notch1 activation in post-treatment tumor biopsy specimens when compared to pretreatment levels.

Endpoints: The primary endpoint will be the level of expression of full length Notch1, cleaved Notch1, HES-1, and ASCL-1, as measured by Western blot using quantitative densitometry. The pre-treatment and post-treatment biopsies will be processed and analyzed simultaneously so as to minimize inter-test variability.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Demonstrate that resveratrol at 5 gm per day will be well tolerated with minimal dose limiting toxicities in this patient population.
Time Frame: 1 year
Frequency of grade three or greater toxicities as defined by the NCI Common Toxicity Criteria.
1 year
Describe the effect of resveratrol on tumor growth as demonstrated by standard cross sectional imaging and tumor markers.
Time Frame: 1 year
The level of tumor markers (eg, chromogranin, 5-HIAA, gastrin, and others) pre-treatment will be compared to the post-treatment levels (collected every three months) as a measure of tumor response. In addition, serial axial imaging will be used to document tumor response rates according to standard Response Evaluation Criteria in Solid Tumors (RECIST).
