Clinical Study of the Effect of Two Experimental Lozenges on Oral Malodor After Single Use
NCT05950529 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to compare the control of oral malodor between an investigational lozenge with the enzyme polyphenol oxidase plus green coffee extract or an investigational lozenge with color and flavor along with the enzyme polyphenol oxidase plus green coffee extract in generally healthy subjects. Safety will be evaluated also. Subjects will be randomly assigned to one of four study groups (group code: A, B, C or D): * Experimental lozenge with the enzyme Polyphenol oxidase and green coffee extract * Experimental lozenge with the enzyme Polyphenol oxidase, green coffee extract and flavor * Placebo lozenge control (sorbitol only) * No product control Subjects will be asked to allow their assigned lozenge to dissolve in the mouth while placed on the dorsal surface of the tongue. Subjects can suck on the lozenge and press the lozenge against the palate; however, the lozenge should not be moved around in the mouth or placed on the buccal mucosa. Subjects should avoid biting or chewing the lozenge and talking while dissolving the lozenge. After the lozenge has completely dissolved, the subject will be instructed to swallow the remaining solution. Immediately (no later than 5 minutes) after subjects use their assigned lozenge product or no product, subjects will receive organoleptic assessments (OI) by the 4-5 trained judges and VSC readings (OralChroma readings). Organoleptic measurements (OI) will be repeated at 30 minutes, 1, 2, 3, and 4 hours following test product use or no test product use. OralChroma measurements will be performed again after 30 minutes, 1, 2, 3, and 4 hours after test product use or no test product. Subjects will complete a post-product performance questionnaire after the 1-hour OI and OralChroma assessments have been administered. Following the 4-hour OralChroma assessment, each subject will receive a final oral soft and hard tissue exam for safety.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05950529
The ClinicalTrials.gov registry entry for NCT05950529 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 156 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Novozymes A/S, which has 3 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Oral Malodor appearing as the primary indexed condition, and to 4 interventions — of which Experimental lozenge with the enzyme Polyphenol oxidase and green coffee extract 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: NCT05950529 reports 1 study location spanning 1 distinct geographic area — top geographies include Indiana. 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.
