An Evaluation of the Impact of a Single Dose of P-552 on Oral Mucosal Wetness

Completed · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Xerostomia, Sjogren's Syndrome

In brief

The primary objective of this clinical study is to determine the impact of P-552 oral rinse on salivary volume after administration of a single dose of P-552and versus vehicle rinse. Changes in oral mucosal wetness will be assessed via collection of salivary output and via measurement of oral wetness using the Periotron 8000 instrument.

• Has minimal level of unstimulated whole mouth salivary flow (greater than or equal to 0.05 milliliters [i.e., 0.05 grams] per 5 minutes) at the screening visit.
• Have a diagnosis of primary Sjogren's syndrome consistent with the revised version of the European criteria proposed by the American-European Consensus Group European Cooperative Community Classification Criteria for Sjogren's Syndrome.

You may not qualify if…

• Is unable to maintain a stable dosage regimen of any concomitant medication throughout the duration of the trial.
• Shows evidence of a significant active or ongoing oral infection or other oral conditions (e.g., lichen planus) that, in the opinion of the investigator, might affect the safety of the subject or might exacerbate during study participation.
• Has acutely infected salivary glands (with or without pain) or suspected closure of the salivary glands.
