Clinical Trial Summary

This pilot clinical trial studies freeze-dried black raspberries (BRB) in preventing oral cancer recurrence in high at-risk Appalachian patients previously treated with surgery for oral cancer. Chemoprevention is the use of drugs natural products to keep cancer from developing, progressing, or recurring. Giving freeze-dried black raspberries may prevent oral cancer from forming or returning in oral cancer survivors.

Description:

PRIMARY OBJECTIVES:

I. To conduct an initial early phase clinical study utilizing a high ar-risk and underserved Appalachian population who are former oral cancer patients to determine the practicability of long-term daily freeze-dried black raspberry (BRB) (BRB lozenge) administration and to gain insights into the potential prevention of recurrent oral cancer by BRBs.

SECONDARY OBJECTIVES:

I. Evaluate numerous parameters (recruitment, tolerability, adherence to study guidelines, collection of biological samples, and demographics) that will be helpful in designing a future definitive, randomized, Phase II or III clinical trial structured to assess the potential effects of long-term BRB administration.

II. Evaluate the temporal modulation of BRB-responsive gene expression that favor oral cancer chemoprevention in high at-at risk normal tissues before and after BRB administration.

III. Assess the temporal modulation of BRB-responsive gene expression and biological levels of fruit components in post-surgical oral cancer patients not exposed to BRBs.

OUTLINE: Patients are assigned to 1 of 2 treatment arms.

ARM I: Patients receive freeze-dried black raspberry lozenges orally (PO) 4 times daily (QID) for up to 6 months.

ARM II: Patients do not receive freeze-dried black raspberries lozenges.

After completion of study treatment, patients in Arm I are followed for up to 5 years and patients in Arm II are followed for up to 1 year for oral cancer recurrence.

Eligibility

Inclusion Criteria:

• Patients from any Appalachian County with previously diagnosed, biopsy-proven, surgically resected, oral squamous cell carcinoma (SCC) (stages T1 to T4), which encompasses cancers of the oral cavity including lips, buccal mucosa, teeth, floor of the mouth and gums and those of the oropharynx consisting of the base of the tongue, soft palate, tonsillar area, and the posterior pharyngeal wall will be eligible

• Patients who have followed the advice of their physician and have been definitively treated for their tumor by any method and are currently disease free will be eligible

• Patients may be enrolled as early as their first follow-up post-operative clinic visit after their most recent surgery, but no more than 36 months post-surgery

• Patients must be able to take nutrition/medications orally

• No prior history of intolerance or allergy to berry or berry-containing products

Exclusion Criteria:

• History of intolerance (including hypersensitivity or allergy) to berry or berry-containing products

• Patients who are actively receiving adjuvant therapy (radiation, chemotherapy) will be excluded until such time as they have completed treatments

• Pregnant women; although there are no known adverse effects of black raspberries upon the fetus, if patients become pregnant during period of LBR administration, then LBR will be discontinued and patient will be removed from the study

• Inability to grant informed consent

Intervention

Dietary Supplement:
• BRB Lozenge
ARM I: Patients will be instructed to begin BRB administration and continue daily for up to 6 months.

Other:
• Survey Administration
Patients will complete a baseline survey documenting any family history of cancer. Patients will then provide a history of tobacco, alcohol and mouthwash use, complete the Head and Neck Cancer Inventory Survey (HNCI), the Insomnia Severity Index (ISI) Survey, and the Brief Fatigue Inventory (BFI) Survey. Patients will receive a trial-specific logbook to record their usages.
• Laboratory Biomarker Analysis
Patients will provide blood, urine, saliva, and cheek scrape samples. These biological samples will be evaluated for the presence of BRB components (as a measure of compliance) and assessed for BRB-responsive gene expression, respectively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to recurrence	Two side tests and confidence intervals will be constructed using the exact binomial formulation.	Up to 5 years
Secondary	Adherence rates in patients receiving LBR	Adherence rates for subjects on LBR will be evaluated using 95% confidence intervals based on the exact binomial formulation (margins of error will be approximately 8% based on an expected compliance rate near 75% of subjects).	Up to 5 years
Secondary	LBR-responsive gene expression before, during, and after LBR administration (Arm I)	Reverse transcriptase polymerase chain reaction (RT-PCR) data will be analyzed on the log scale using repeated measures analysis of variance (ANOVA) models and the Bonferroni correction to adjust for the multiple inference problem	Up to 5 years
Secondary	LBR-responsive gene expression in patients not exposed to LBR (Arm II)	Reverse transcriptase polymerase chain reaction (RT-PCR) data will be analyzed on the log scale using repeated measures analysis of variance (ANOVA) models and the Bonferroni correction to adjust for the multiple inference problem.	Up to 5 years
Secondary	LBR responsive gene activity and time to recurrence	RT-PCR data will be analyzed on the log scale using repeated measures ANOVA models and the Bonferroni correction to adjust for the multiple inference problem. Genes that show changes with berries will also be compared with to a control group of 30 subjects who refuse LBR treatment but agree to be included in biomarker studies and for whom baseline alcohol and smoking history will be available	Up to 5 years
