Actavis and Adamas Pharmaceuticals today announced that the U.S. Food and Drug Administration (FDA) has approved the New Drug Application (NDA) for Namzaric, a fixed-dose combination (FDC) of memantine hydrochloride extended-release, a NMDA receptor antagonist, and donepezil hydrochloride, an acetylcholinesterase inhibitor. Namzaric was approved for the treatment of moderate to severe dementia of the Alzheimer’s type in patients stabilized on memantine hydrochloride and donepezil hydrochloride.
Namzaric combines, in one capsule, two complementary therapeutic agents which are often co-prescribed as approximately 70% of Namenda XR patients are also on AChEI therapy. Both Namenda XR and donepezil have proven efficacy and safety, for the treatment of moderate to severe Alzheimer’s disease. Additionally, data has shown that combination therapy with Namenda XR and an AChEI demonstrated greater improvement in cognition and global function verses an AChEI alone,” said David Nicholson, Actavis Senior Vice President, Global Brands R&D. “Along with our partner Adamas, we are proud that this important therapy will provide a convenient and innovative treatment option for Alzheimer’s patients and caregivers that reduces the number of capsules they are required to take each day for the treatment of this devastating disease.”
“We are excited about the approval of Namzaric – the first fixed-dose combination of extended-release memantine and donepezil – and look forward to its launch by Actavis in 2015,” said Gregory T. Went, Ph.D., Chairman and CEO of Adamas Pharmaceuticals, Inc. “Namzaric is also the first FDA-approved FDC product to emerge from Adamas’ platform for modifying the pharmacokinetic profiles of approved drugs, and we look forward to developing additional new treatments for individuals with serious neurological CNS disorders.”
