Brief summary

This phase I trial studies the side effects and the best dose of muscadine grape skin extract (MGE) in treating patients with malignancy (tumor or cancer) that has spread to other parts of the body or cannot be removed by surgery. MGE is a nutritional supplement containing an extract of the skin of muscadine grape that has shown anti-cancer activity in laboratory studies and may be able to fight or kill malignant cells.

Detailed description

PRIMARY OBJECTIVES: I. To determine the safety and maximum tolerated dose (MTD) of MGE (muscadine grape skin extract) after 4 weeks of administration for patients with metastatic cancer. Secondary Objectives: I. To monitor adverse events/toxicity every 4 weeks while on treatment. II. To evaluate change in phenolic levels (total and component, blood and urine) from baseline to 4 and 8 weeks. III. To evaluate change in serum cytokines and growth factors from baseline to 4 and 8 weeks on MGE. IV. To observe the response rate of MGE in patients with metastatic cancer. V. To assess overall and progression-free survival in patients with metastatic cancer receiving MGE. VI. To assess global quality of life (Functional Assessment of Cancer Therapy-General \[FACT-G\] and fatigue (Patient Reported Outcomes Measurement Information System \[PROMIS\]-fatigue Short Form \[SF\]) in cancer patients taking MGE. VII. To assess adherence to MGE treatment. OUTLINE: This is a dose-escalation study. Patients receive muscadine grape skin extract orally (PO) twice daily (BID). Treatment continues for 8 weeks in the absence of disease progression or unacceptable toxicity. Patients experiencing benefit from muscadine grape skin extract may continue treatment in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 30 days and then every 6 weeks.

MeasureTime frameDescription
Number of Participants With Dose-Limiting Toxicity29 daysMaximum tolerable dose of muscadine grape extract is defined as the dose level immediately below the dose level that induced a dose-limiting toxicity (DLT) in \>= 2 patients, as assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0DLT will be assessed by severity of adverse events.

Secondary

MeasureTime frameDescription
Best ResponseAt the end of treatment, up to 1 yearBest response will be characterized using a frequency table. Evaluation of new or enlarging effusions to differentiate between Progressive Disease and Response/Stable Disease. Measurements will be obtained from usual care imaging and assessed by the principal investigators in confirmation with the physician of record. Clinical lesions will only be considered measurable when they are superficial and ≥10 mm in diameter as assessed using calipers. For the case of skin lesions, documentation by color photography, including a ruler to estimate the size of the lesion, is recommended.
Change in Total Phenolic Levels in BloodBaseline to up to 8 weeksA mixed model analysis of variance (ANOVA) model will be fit with phenolic level as the outcome and time (baseline, 4, and 8 weeks) as a fixed effect and subject as a random effect. Contrasts will be used to estimate the changes from baseline to week 4 and week 8.
Change in Total Phenolic Levels in UrineBaseline to up to 8 weeksA mixed model analysis of variance (ANOVA) model will be fit with phenolic level as the outcome and time (baseline, 4, and 8 weeks) as a fixed effect and subject as a random effect. Contrasts will be used to estimate the changes from baseline to week 4 and week 8.
Change in Quality of Life and Fatigue in Cancer Patients Taking MGE as Measured by FACT-GBaseline to up to 1 yearA mixed model ANOVA model will be fit with phenolic level as the outcome and time (baseline, every 4 weeks) as a fixed effect and subject as a random effect. Contrasts will be use to estimate changes from baseline to each follow-up time period. Score scales from 0 (not at all) to 4 (very much). Sum of scores range 0-28 for social, functional and physical well being and 0-24 for emotional well being and multiplied by 6. All four scores are totaled with a score range of 0-108. A mean of the combined group scores will be used. A higher score indicates a higher worse outcome of the illness on the participant.
Change in Systemic Cytokine LevelsBaseline to up to 8 weeksA mixed model ANOVA model will fit with the outcome of interest (cytokine or growth factor) as the outcome and time (baseline, 4, and 8 weeks) as a fixed effect and subject as a random effect. Contrasts will be used to estimate the changes from baseline to week 4 and week 8.
Incidence of Adverse Events (AEs), Assessed Using NCI CTCAE Version 4.0Up to 1 yearAEs/toxicity will be assessed at weeks 4, 8 and every 4 weeks thereafter if patients remain on treatment. Any expected toxicities, any laboratory based toxicities, and any grade 3 or higher gastrointestinal toxicities, and any grade 4 or higher toxicities will be summarized using frequency tables overall and by week.
Overall Response Rate of MGE (Complete Response, Partial Response, and Stable Disease)At 8 weeksResponse will be characterized using a frequency table.
Adherence to MGE Treatment, as Measured by Percent of Pills Taken at the End of Every 4 Week PeriodUp to 1 yearPill count will be calculated from counting the number of pills returned as well as by summarizing the patient's pill diary. The percent of pills taken will be summarized by dose level using the median and 95% confidence interval.

Primary

Number of Participants With Dose-Limiting Toxicity

Maximum tolerable dose of muscadine grape extract is defined as the dose level immediately below the dose level that induced a dose-limiting toxicity (DLT) in \>= 2 patients, as assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0DLT will be assessed by severity of adverse events.

Time frame: 29 days

Population: As pre-specified in the protocol, data collection and analysis for all arms will be combined. MTD was not determined, as there was not a dose level with ≥2 dose limiting toxicities (DLT). One DLT at dose level 2 and therefore 3 additional participants were enrolled. No subsequent DLTs and the study was stopped at dose level 5, per protocol.

Adherence to MGE Treatment, as Measured by Percent of Pills Taken at the End of Every 4 Week Period

Pill count will be calculated from counting the number of pills returned as well as by summarizing the patient's pill diary. The percent of pills taken will be summarized by dose level using the median and 95% confidence interval. Investigators will summarize the percent of pills taken at the end of every 4 week period i using the formula: Percent of pills taken)i = (Dose Level ×7 ×4)i minus Pill Count divided by Dose Level ×7 ×4)i

Time frame: Up to 1 year

Population: As pre-specified in the protocol, this study is not intended to be analyzed by arm for most analyses and data collection. Analysis for all arms will be combined for Adherence to EMG treatment.

A mixed model analysis of variance (ANOVA) model will be fit with phenolic level as the outcome and time (baseline, 4, and 8 weeks) as a fixed effect and subject as a random effect. Contrasts will be used to estimate the changes from baseline to week 4 and week 8.

Time frame: Baseline to up to 8 weeks

Population: As pre-specified in the protocol, this study is not intended to be analyzed by arm for most analyses and data collection. Analysis for all arms will be combined for change in total phenolic levels in blood.

Incidence of Adverse Events (AEs), Assessed Using NCI CTCAE Version 4.0

AEs/toxicity will be assessed at weeks 4, 8 and every 4 weeks thereafter if patients remain on treatment. Any expected toxicities, any laboratory based toxicities, and any grade 3 or higher gastrointestinal toxicities, and any grade 4 or higher toxicities will be summarized using frequency tables overall and by week.

Time frame: Up to 1 year

Overall Response Rate of MGE (Complete Response, Partial Response, and Stable Disease)

Response will be characterized using a frequency table.

Time frame: At 8 weeks

Population: As pre-specified in the protocol, data will be collected and analyzed for all arms combined. At 8 weeks, only 16 patients were evaluable.

Overall Survival (OS)

OS will summarized using the Kaplan-Meier method. Median survival rates and associated 95% confidence intervals will be calculated.

Time frame: Up to 4 years

Population: As pre-specified in the protocol, this study is not intended to be analyzed by arm for most analyses and data collection. Analysis for all arms will be combined for overall survival.
