Adamas Litigation

In November 2012, Adamas Pharmaceuticals, Inc. (Adamas) granted Forest Laboratories Holdings Limited, an indirect wholly-owned subsidiary of Allergan plc (Forest), an exclusive license to certain of Adamas's intellectual property rights relating to human therapeutics containing memantine in the United States. Under the terms of that license agreement, Forest has the right to enforce such intellectual property rights which are related to its right to market and sell Namzaric and NAMENDA XR for the treatment of moderate to severe dementia related to Alzheimer's disease. Adamas has a right to participate in, but not control, such enforcement actions by Forest.

Since 2018 multiple generic companies have launched generic versions of NAMENDA XR. A number of companies have submitted ANDAs including one or more certifications to the FDA, pursuant to 21 U.S.C. § 355(j)(2)(A)(vii)(iv), requesting approval to manufacture and market generic versions of Namzaric, on which Adamas became entitled to receive royalties from Forest beginning in May 2020.

Adamas and Forest have settled with all such Namzaric ANDA filers, including all first filers on all the available dosage forms of Namzaric. Subject to those agreements
