Orexigen Therapeutics Announces Spanish Launch of Mysimba® (naltrexone HCl / bupropion HCl prolonged release) in Partnership with Laboratorios Farmacéuticos Rovi, S.A.

SAN DIEGO, Jan. 25, 2017 /PRNewswire/ -- Orexigen Therapeutics, Inc. (NASDAQ: OREX) today announced that Laboratorios Farmacéuticos Rovi, S.A. (ROVI) has launched Mysimba in Spain. Mysimba is approved by the European Medicines Agency for the management of weight in adult patients (≥18 years) with an initial Body Mass Index (BMI) of ≥ 30 kg/m2 (obese), or ≥ 27 kg/m2 to < 30 kg/m2 (overweight) in the presence of one or more weight-related co-morbidities (e.g., type 2 diabetes, dyslipidaemia, or controlled hypertension). ROVI will market Mysimba as part of their diversified pharmaceutical portfolio under the terms of our distributorship agreement signed in August 2016.

"The launch of Mysimba in Spain is an important milestone in our partnership with ROVI, a company who shares our objective to improve the quality of life for patients who are overweight or struggle with obesity," said Mike Narachi, President and Chief Executive Officer of Orexigen. "With this launch, Mysimba is now available for patients in six countries in Europe.  We expect to continue to grow availability of this important therapeutic option for weight management with launches in ten additional European countries in 2017."

Obesity and related comorbidities are a significant health problem in Spain, where approximately 53% of adults are overweight or struggling with obesity, according to recent statistics from the Spanish National Statistics Institute.

Orexigen's partnership with ROVI is a part of the Company's ex-U.S. strategy to establish commercial and distribution partnerships with companies committed to our mission of helping patients struggling to lose weight.  Following a successful partnering process in 2016, Orexigen currently has commercialization arrangements with five different partners covering 38 countries.

About Mysimba
Mysimba is approved in the European Union for use as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of 30 kg/m2 or greater (obese), or 27 kg/m2 or greater (overweight) in the presence of at least one weight-related comorbid condition (e.g., hypertension, type 2 diabetes mellitus or dyslipidemia). In the United States, the drug is approved as Contrave® (naltrexone HCl / bupropion HCl extended release).

The exact neurochemical effects of Mysimba / Contrave leading to weight loss are not fully understood. Mysimba / Contrave has two components: naltrexone, an opioid antagonist, and bupropion, a relatively weak inhibitor of the neuronal reuptake of dopamine and norepinephrine. Nonclinical studies suggest that naltrexone and bupropion have effects on two separate areas of the brain involved in the regulation of food intake: the hypothalamus (appetite regulatory center) and the mesolimbic dopamine circuit (reward system).

Four 56-week multicenter, double-blind, placebo-controlled Phase 3 clinical trials were conducted to evaluate the effect of Mysimba / Contrave in conjunction with lifestyle modification in 4,536 subjects randomized to Mysimba / Contrave or placebo. In these studies, the most common adverse reactions (>5 percent) seen in patients taking Mysimba / Contrave included nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea.

The clinical trial program also included a double-blind, placebo-controlled cardiovascular outcomes trial known as the Light Study. The primary objective of this study was to evaluate the occurrence of major adverse cardiovascular events (MACE) in overweight and obese adults with cardiovascular risk factors receiving Contrave. A second study, designed to address post-approval requirements in both Europe and the United States, is planned in order to further evaluate cardiovascular outcomes.
