Neos Therapeutics Announces Issuance of New U.S. Methods of Use Patent for N-desethyloxybutynin-- N-desethyloxybutynin is the active ingredient in NT0502, the company’s development candidate for the treatment of sialorrhea --

Published: Apr 09, 2020

DALLAS and FORT WORTH, Texas, April 09, 2020 (GLOBE NEWSWIRE) -- Neos Therapeutics, Inc. (NASDAQ: NEOS), a commercial-stage pharmaceutical company developing and manufacturing central nervous system-focused products, today announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,610,507, which is directed to methods of treating sialorrhea by administering N-desethyloxybutynin, the active pharmaceutical ingredient in NT0502. NT0502 is currently in Phase 1 clinical development for the treatment of sialorrhea in patients with neurological conditions. The patent, assigned to Neos Therapeutics, is not expected to expire before November 2032.

“We are very pleased to have secured this important method of use patent from the USPTO. The issuance of this patent further supports our efforts to explore the potential of NT0502 to treat sialorrhea in patients with neurological disorders, particularly Parkinson’s Disease, given the significant psychosocial and medical impact they experience,” said Jerry McLaughlin, President and Chief Executive Officer. “We remain on track to initiate a Phase 1 single ascending and multiple ascending dose clinical trial of NT0502 in the second half of 2020, and look forward to reporting the data from this trial.”

About NT0502
NT0502 (N-desethyloxybutynin) is a new chemical entity being developed as an oral, once- or twice-daily treatment to reduce chronic sialorrhea in patients with neurological and other conditions associated with excess saliva and drooling. Based on preclinical data, the company believes that NT0502 offers the potential for an improved tolerability profile and an easier-to-dose oral formulation, without the need for complex titration, compared to existing treatment options. N-desethyloxybutynin is an active metabolite of oxybutynin, an approved drug to treat a urological condition.

About Sialorrhea
Sialorrhea is defined as prevalent and excessive drooling from the mouth as a result of limitations in a person’s ability to control and swallow oral secretions1,2. Sialorrhea can lead to significant physical and psychosocial complications, including perioral chapping, aspiration, dehydration, infection, foul odor, stigmatization, and increased dependency and level of care, all of which can create an additional burden for these medically complicated patients1,3. In the U.S., more than 1.4 million patients – including those suffering from Parkinson’s disease4,5, cerebral palsy6,7, stroke8,9, traumatic brain injury10, ALS11 and other neurological conditions12,13 – experience sialorrhea due to neuromuscular/sensory dysfunction. Many of these patients remain untreated today because existing non-selective anticholinergic agents are associated with treatment-limiting side effects and cumbersome dosing schedules.
