Novel, Oral, Investigational Medicine for the Treatment of Agitation in Alzheimer’s Disease and Other Psychiatric Indications

DUBLIN, Ireland I January 25, 2016Alkermes plc (NASDAQ: ALKS) today announced the initiation of a phase 1 clinical study of ALKS 7119, an oral, investigational drug candidate being developed for the treatment of agitation in patients with Alzheimer’s disease (AD) and other central nervous system (CNS) indications. The double-blind, placebo-controlled study will evaluate the safety and tolerability of single ascending doses of ALKS 7119 in approximately 60 healthy subjects. ALKS 7119 is a novel small molecule that acts on multiple key receptor systems in the brain.

“Agitation is a common and debilitating psychiatric symptom of Alzheimer’s disease that currently has no approved medicines, and causes significant burden on patients and their caregivers,” commented Elliot Ehrich, M.D., Chief Medical Officer of Alkermes. “We believe that the multivalent mechanism of ALKS 7119 has promising potential to treat agitation associated with Alzheimer’s disease and other important psychiatric indications. With the successful completion of a thorough preclinical development phase, we are excited to launch our clinical program and look forward to seeing the results from this phase 1 study later this year.”

The randomized, double-blind, placebo-controlled, multi-cohort, phase 1 study will investigate the safety and tolerability of single ascending doses of ALKS 7119 following oral administration in approximately 60 healthy male adults. The study will also include a battery of psychometric assessments, which are intended to provide preliminary insight into the potential human pharmacodynamic response. Results from this phase 1 study are expected in the second half of 2016.

About ALKS 7119
ALKS 7119 is a novel chemical entity that has a multivalent mechanism of action and acts on key receptors in the brain involved in several central nervous system (CNS) diseases. In addition to the potential treatment of agitation in patients with Alzheimer’s disease, ALKS 7119 may be investigated for the treatment of major depressive disorder and other psychiatric conditions. ALKS 7119 is a N-methyl-D-aspartate (NMDA) receptor antagonist and a serotonin reuptake inhibitor. It also binds to other targets, which may contribute to its pharmacodynamic effects.

About Alzheimer’s Disease
Alzheimer’s disease (AD) is a progressive brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks.1 While cognitive decline is a central feature of the disease, psychiatric symptoms, such as agitation, are the leading source of morbidity and caregiver burden.2 There are currently no approved medications in the U.S. for the treatment of Alzheimer’s agitation. Approximately 5.3 million individuals in the U.S. had AD in 2015, and this number is expected to nearly triple by 2050.3
