Alkermes to Showcase Leadership in Schizophrenia With New Data Presentations at Upcoming Scientific Conferences

-- Clinical Data and Health Economics and Outcomes Research to be Presented
May 18-22, 2019 at APA and ISPOR Annual Meetings --

DUBLIN, May 13, 2019 /PRNewswire/ -- Alkermes plc (Nasdaq: ALKS) today announced that it will present data from its mental health portfolio at the American Psychiatric Association (APA) Annual Meeting in San Francisco and the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) 2019 Conference in New Orleans; both scientific conferences will be held May 18-22, 2019. These presentations underscore Alkermes' growing scientific and clinical presence in the mental health space broadly, and specifically in schizophrenia, and demonstrate the company's commitment to developing new treatment options for patients that aim to provide both strong antipsychotic efficacy and patient-focused safety and tolerability attributes.

"APA and ISPOR are two of the most important meetings of the year for mental health experts and health economics leaders to engage in scientific exchange," said Kanchan Relwani, Vice President of Medical Affairs at Alkermes. "Alkermes has a strong legacy in schizophrenia and addiction, two critical and urgent public health issues in the U.S., and we remain committed to developing new therapies that help address patient needs in these important areas. We look forward to presenting new data to key decision-makers, thought leaders and practitioners."

Highlights of the upcoming presentations at APA include a poster reviewing antipsychotic efficacy results from three double-blind, olanzapine-controlled randomized clinical studies of ALKS 3831 (olanzapine/samidorphan), as well as posters relating to addiction and major depressive disorder. At ISPOR, Alkermes will share insights on the economic burdens of schizophrenia and bipolar I disorder from systematic literature reviews, and will present findings from two qualitative studies exploring patients' treatment experiences with oral antipsychotic medications in individuals with schizophrenia or bipolar I disorder.

"There is increasing recognition in the healthcare community and society at large of the tremendous toll that mental health disorders place on all layers of the healthcare ecosystem, from individual patients, to caregivers, providers and insurers," said Amy O'Sullivan, Vice President of Health Economics and Outcomes Research at Alkermes. "Today, innovators must consider not only the direct clinical impact of new treatment options for patients, but also the potential economic impact of such medications in addressing the costs of previously untreated or undertreated diseases. These economic and patient considerations help inform our development programs, and we look forward to sharing new insights at ISPOR that underscore the ongoing need for new disease management options for patients with schizophrenia and bipolar disorder."
