Adamas Announces Issuance Of New Patents For GOCOVRI And ADS-4101

Adamas Pharmaceuticals, Inc. (NASDAQ:ADMS), a company dedicated to developing and delivering medicines that make a meaningful difference to people affected by neurological diseases, today announces the issuance of two patents covering GOCOVRI(r) (amantadine) extended-release capsules: U.S. Patent No. 11,065,213 issued on July 20, 2021, and U.S. Patent No. 11,077,073, projected to issue on August 3, 2021. These two patents are the first issued in this patent family and provide additional claims covering the drug product GOCOVRI, the company's medicine approved as the first and only drug to treat both dyskinesia and OFF motor complications in Parkinson's patients, and methods of using GOCOVRI.

GOCOVRI is indicated for the treatment of dyskinesia in patients with Parkinson's disease (PD) receiving levodopa-based therapy, with or without concomitant dopaminergic medications and as an adjunctive treatment to levodopa/carbidopa in patients with PD experiencing OFF episodes. Data from two pivotal, placebo-controlled phase 3 clinical studies showed that GOCOVRI reduced dyskinesia in people with Parkinson's, as well as a secondary benefit in reduction of OFF time, leading to an increase in good ON time.

With the issuance of these two patents, Adamas' portfolio of patents for GOCOVRI now includes 17 U.S. patents across four separate patent families that will expire from 2025 to 2038. These latest patents will be listed in the U.S. Food and Drug Administration's (FDA) Approved Drug Products with Therapeutic Equivalent Evaluations, commonly known as the Orange Book. Adamas previously announced settlement agreements with first filers for both available strengths of GOCOVRI, granting non-exclusive licenses from March 4, 2030, or earlier in certain circumstances.

In addition to these two new patents for GOCOVRI, Adamas recently received a new patent covering ADS-4101, its investigational drug candidate being considered for partnering opportunities. This patent, which follows two recently announced U.S. patents for ADS-4101, has been issued in Japan (Japan Patent No. 6902033), and is the first granted in a major market country outside the U.S.
