Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this phase 0 Window of Opportunity study is to have subjects with Head and Neck Squamous Cell Carcinoma (HNSCC) receive same dosage of Black Raspberry Extract between their cancer diagnosis and standard treatment (surgery). Tumor biopsies and research blood before and after the investigational treatment (Black Raspberry Extract lozenges) are collected for translational research. The investigational treatment is kept short to avoid delaying standard treatment.
