Effect of Black Raspberry Phytochemicals on Oral Microbiome in Current Smokers and Non-smokers
NCT02439255 · View on ClinicalTrials.gov ↗
Study Summary
This randomized clinical trial studies the effects of black raspberry compounds (phytochemicals) on the bacteria in the mouth (oral microbiome) of current smokers and non-smokers. The oral microbiome protects the body from pathogenic bacteria. Smoking alters the oral microbiome and may increase the susceptibility to cancer by modulating normal host-bacteria interactions. Black raspberry phytochemicals may protect the oral microbiome of smokers and may lower their risk of developing oral cancer.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02439255
The ClinicalTrials.gov registry entry for NCT02439255 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 148 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Ohio State University Comprehensive Cancer Center, which has 291 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Tobacco Use Disorder appearing as the primary indexed condition, and to 4 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02439255 reports 1 study location spanning 1 distinct geographic area — top geographies include Ohio. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
