Prisyna Announces Publication of Research Demonstrating Synvaza’s Effect on Oral Lesion Relief

— Synvaza reduces pain associated with erosive or ulcerative oral lesions —

CLAREMONT, Calif. – July 11, 2018 – Prisyna, the oral care division of Synedgen, founded to optimize oral health using advanced, proprietary glycomics technology, today announced new research showing that Synvaza®, an oral rinse product, reduced mucosal pain without anesthetic effect and improved oral function in patients with ulcerative oral mucosal lesions. The study, “Efficacy of a glycopolymer-based oral rinse upon pain associated with ulcerative and erosive lesions of the oral mucosa: A within-subject pilot study,” was published in Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology.

The pilot study was powered to evaluate the efficacy of Synvaza in reducing pain associated with existing erosive or ulcerative lesions of the oral mucosa and to understand the magnitude of the effect on pain reduction in order to power future studies. Results showed that Synvaza significantly reduced severity in all measures of oral soreness from baseline to 72 hours.

Twenty-five subjects with ulcerative/erosion lesions and moderate pain were enrolled in this open label study. They were provided with a 72-hour supply of Synvaza and instructed to use as needed for 72 hours with a minimum frequency of two times per day, swished for one minute at each use, with the first dose used upon awakening and the last dose just before bedtime. At the start of the study, and 24, 48 and 72 hours after first product use, subjects completed surveys in which they documented pain scores and oral symptoms, including mouth and throat soreness, domain-specific problems with eating, drinking, swallowing, talking, sleeping, and general symptoms of dry mouth and mouth and throat lining sensitivity and pain. Ratings ranged from zero, representing an absence of symptoms, to ten, representing the most severe degree of symptoms.

The overall soreness score showed a continuous decline across the four-time points and all of the oral soreness scores had a statistically significant decrease from baseline to 72 hours. The largest domain-specific decrease from baseline to 72 hours was for oral soreness associated with talking (67%), followed by drinking (62%), swallowing (56%), sleeping (51%), and eating (50%). Overall soreness from baseline to 72 hours decreased by 28%.

“The study showed reductions in mouth or throat pain, changes in dry mouth and sensitivity of the lining of the mouth and throat to spicy, hot or acidic foods, which may represent a meaningful improvement in quality of life for patients,” said lead author Joel B. Epstein, DMD, MSD. “Additionally, early pain reduction was commonly reported, with a cumulative effect that appeared to increase with successive rinse applications for the duration of the study, implying a potentially broad range of effect upon painful oral mucosal conditions.”

“Synvaza addresses the needs of patients who suffer from the pain of oral lesions, which can have a substantial negative effect on their daily routine and in more acute circumstances can be quite debilitating,” stated Leo Pranitis, Prisyna General Manager. “We look forward to the continued study and development of Synvaza to potentially provide relief for patients suffering from ulcerative oral mucosal lesions as part of our commitment to addressing a broad range of patient oral care needs using our innovative glycomics technology.”
