Lorcaserin Data to be Presented at The Obesity Society's Annual Scientific Meeting

WOODCLIFF LAKE, N.J. and SAN DIEGO, Oct. 31, 2014 /PRNewswire/ -- Eisai Inc. and Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) announced today that data for BELVIQ^® (lorcaserin HCl) CIV will be presented during ObesityWeek^SM hosted by The Obesity Society and the American Society for Metabolic and Bariatric Surgery. The meeting is taking place November 2-7, 2014, in Boston, Massachusetts. There will be one oral presentation and seven poster presentations.

"Obesity is a complex and chronic disease that is often associated with multiple comorbid conditions," said Elisa Fabbrini, MD, PhD, Assistant Professor in Medicine, Washington University School of Medicine in St. Louis. "The lorcaserin data analyses scheduled for presentation demonstrate the need for ongoing research in the area of weight management programs."

BELVIQ is a serotonin 2C receptor agonist approved in the United States as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults who have a body mass index (BMI) of 30 kg/m² or greater (obese), or BMI of 27 kg/m² or greater (overweight) with at least one weight-related medical condition such as high blood pressure, high cholesterol, or type 2 diabetes. It is not known if BELVIQ is safe and effective when taken with other prescription, over-the-counter, or herbal weight loss products, nor is it known if BELVIQ changes the risk of heart problems or stroke, or death due to heart problems or stroke.

"These data presentations taking place during ObesityWeek support Eisai's commitment to advancing the understanding of obesity, a chronic, progressive disease that has serious consequences, and the role of lorcaserin in this patient population," said Gary Palmer, MD, Chief Medical Officer at Eisai Inc.

IMPORTANT SAFETY INFORMATION

Contraindication

• BELVIQ should not be taken during pregnancy or by women who are planning to become pregnant.

Warnings and Precautions

• BELVIQ is a serotonergic drug. The development of potentially life-threatening serotonin syndrome or Neuroleptic Malignant Syndrome (NMS)-like reactions have been reported during use of serotonergic drugs, including, but not limited to, selective serotonin-norepinephrine reuptake inhibitors, and selective serotonin reuptake inhibitors, tricyclic antidepressants, bupropion, triptans, dietary supplements such as St. John's Wort and tryptophan, drugs that impair metabolism of serotonin (including monoamine oxidase inhibitors), dextromethorphan, lithium, tramadol, antipsychotics or other dopamine antagonists, particularly when used in combination. Patients should be monitored for the emergence of serotonin syndrome symptoms or NMS-like reactions, including agitation, hallucinations, coma, tachycardia, labile blood pressure, hyperthermia, hyperreflexia, incoordination, nausea, vomiting, diarrhea, and muscle rigidity. Treatment with BELVIQ and any concomitant serotonergic or antidopaminergic agents should be discontinued immediately if the above events occur, and supportive symptomatic treatment should be initiated.
• Patients should not take BELVIQ in combination with drugs that have been associated with valvular heart disease (e.g., cabergoline). In clinical trials, 2.4% of patients taking BELVIQ and 2.0% of patients taking placebo developed valvular regurgitation: none of these patients was symptomatic. BELVIQ should be used with caution in patients with congestive heart failure (CHF). Patients who develop signs and symptoms of valvular heart disease, including dyspnea, dependent edema, CHF, or a new cardiac murmur, should be evaluated and discontinuation of BELVIQ should be considered.
• Impairment in attention, memory, somnolence, confusion, and fatigue, have been reported in patients taking BELVIQ. Patients should not drive a car or operate heavy machinery until they know how BELVIQ affects them.
• The recommended dose of 10 mg twice daily should not be exceeded, as higher doses may cause euphoria, hallucination, and dissociation. Monitor patients for the development or worsening of depression, suicidal thoughts or behaviors, and/or any changes in mood. Discontinue BELVIQ in patients who develop suicidal thoughts or behaviors.
• Weight loss may increase the risk of hypoglycemia in patients with type 2 diabetes mellitus who are being treated with antidiabetic medications, so measurement of blood sugar levels before and during treatment with BELVIQ is recommended. Decreases in doses of antidiabetic medications or changes in medication regimen should be considered.
• Men who experience priapism should immediately discontinue BELVIQ and seek emergency medical attention. BELVIQ should be used with caution with erectile dysfunction medications. BELVIQ should be used with caution in men who have conditions that might predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia), or in men with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie's disease).
• Because BELVIQ may cause a slow heartbeat, it should be used with caution in patients with a history of bradycardia or heart block greater than first degree.
• Consider monitoring for CBC changes, prolactin excess, and pulmonary hypertension.

Most Common Adverse Reactions

• In patients without diabetes: headache (17%), dizziness (9%), fatigue (7%), nausea (8%), dry mouth (5%), and constipation (6%).
• In patients with diabetes: hypoglycemia (29%), headache (15%), back pain (12%), cough (8%), and fatigue (7%).

Nursing Mothers

• BELVIQ should not be taken by women who are nursing.

BELVIQ is a federally controlled substance (CIV) because it may be abused or lead to drug dependence.
