Tris Pharma, a specialty pharmaceutical company that develops innovative drug delivery technologies, recently announced that the US FDA has approved its first two NDAs based on its proprietary OralXR+ platform technology, including the first-ever 24-hour liquid sustained-release product.  

OralXR+ is a portfolio of dosage forms based on a patent-pending sustained-release particles-driven technology. Tris creates extremely fine, taste-masked, sustained-release particles that can deliver drug over time. The particles are coated with a highly flexile, insoluble, water-based polymer, resulting in highly durable particles that can be used in an array of dosage forms, including liquid suspensions, ODT, chewable tablets, and film strips as well as traditional tablets or capsules.

The NDA approvals received were for once-daily Clonidine ER Suspension and once-daily Clonidine ER Tablets in two different strengths. Clonidine, a heavily prescribed medication is a direct-acting alpha 2 adrenergic agonist, which has been prescribed historically as an antihypertensive agent. Until Tris Pharma's approval, there were no once-daily oral Clonidine products available.  

"The suspension represents a true leap forward for drug delivery in that it is the first-ever FDA-approved 24-hour sustained-release liquid formulation," said Ketan Mehta, CEO and President of Tris Pharma. "These two NDAs further validate Tris' pioneering work in the field of liquid sustained release. This is a testament to the people of Tris Pharma's relentless work and dedicated efforts to make this a reality."

Liquid sustained-release stands apart from traditional ER solid dose in that it allows physicians a limitless number of dose options because the dose can be customized through titration. It also allows patients who have difficulty swallowing pills, typically young children and the elderly, realize the convenience and compliance benefits of drug delivery.  

"This will be particularly valuable as the technology is leveraged in the development of CNS, pain, and other important therapeutic dose-ranging compounds," added Dr. Yu-Hsing Tu, Tris' Head of R&D. “Tris Pharma has a robust pipeline of more than 20 extended-release products in different therapeutic categories currently in development.”

Tris Pharma is a privately owned, product-focused, specialty pharmaceutical company engaged in the research and development of innovative drug delivery technologies. Through its OralXR+ platform, Tris has pioneered the delivery of sustained release in the liquid, chewable/ODT, and strip dosage forms so patients do not have to swallow a pill. Tris' Nobuse platform provides abuse-deterrence for opioids and other abuse-prone drugs. The company has more than 20 Rx and OTC products in development with pharmaceutical partners. Tris' R&D and manufacturing facilities are located in Monmouth Junction, New Jersey.
