Eisai and Arena Pharmaceuticals Announce Completion of Enrollment in BELVIQ® (lorcaserin HCl) CAMELLIA-TIMI 61 Study

WOODCLIFF LAKE, N.J. and SAN DIEGO, Dec. 1, 2015 /PRNewswire/ -- Eisai Inc. and Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) today announced that the CAMELLIA-TIMI 61 study has reached its target enrollment of 12,000 patients at more than 470 sites in eight countries. The CAMELLIA-TIMI 61 outcomes study is designed to evaluate the impact of long-term treatment with BELVIQ^® (lorcaserin HCl) CIV on the incidence of major adverse cardiovascular events and conversion to type 2 diabetes mellitus in obese and overweight patients with cardiovascular disease and/or multiple cardiovascular risk factors.

"We are pleased to see full enrollment in this important study, which will advance scientific understanding of the long-term safety and efficacy of BELVIQ in overweight and obese patients," said Andrew Satlin, MD, Executive Vice President, Neuroscience and General Medicine PCU, Eisai Inc. "As a company focused on human health care, we are committed to increasing our knowledge of the effects of BELVIQ on cardiovascular health."

The five-year study, conducted in partnership with the Thrombolysis in Myocardial Infarction (TIMI) Study Group, will address the post-marketing requirement from the U.S. Food and Drug Administration to evaluate the long-term cardiovascular safety of BELVIQ. In addition, the study includes two primary efficacy endpoints: (1) to assess the effect of BELVIQ on cardiovascular event risk reduction and (2) to assess the effect of BELVIQ on the conversion to type 2 diabetes mellitus among patients without diabetes at baseline.

"We are very excited that CAMELLIA-TIMI 61 has completed enrollment in such a timely fashion," said Benjamin M. Scirica, MD, MPH, Senior Investigator, TIMI Study Group and Associate Professor of Medicine, Harvard Medical School and Co-Primary Investigator of the CAMELLIA-TIMI 61 Trial. "The enthusiasm and speed of enrollment highlights the commitment to evaluate the efficacy and safety of pharmacotherapy in obese and overweight patients who have cardiovascular disease or are at risk of cardiovascular complications. As the largest ongoing outcomes trial in obesity, CAMELLIA-TIMI 61 will provide invaluable information about this traditionally difficult to treat population."

BELVIQ is used along with 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. BELVIQ is believed to promote satiety and decrease food consumption by selectively activating serotonin 2C receptors in the brain. The exact mechanism of action of BELVIQ is not known.  

"We commend Eisai on the progress they have made in advancing CAMELLIA and on reaching this significant milestone," said Harry F. Hixson, Jr., Arena's interim Chief Executive Officer. "Data from this cardiovascular outcomes trial will provide a better understanding of the potential of long-term treatment with BELVIQ, and we look forward to the study results."

About the Study

The CAMELLIA (Cardiovascular And Metabolic Effects of Lorcaserin In Overweight And Obese Patients) TIMI 61 study is the largest ongoing double-blind, placebo-controlled, parallel-group Phase IIIB/IV study among weight loss medications. The primary safety objective is to evaluate the incidence of major adverse cardiovascular events (MACE), defined as cardiovascular death, myocardial infarction or stroke. If the primary safety objective is met, the co-primary efficacy objectives are to evaluate the impact of BELVIQ on the incidence of: (1) MACE+, defined as MACE or hospitalization due to unstable angina or heart failure, or any coronary revascularization, and (2) conversion to type 2 diabetes mellitus for subjects without diabetes at baseline. In addition, the study will evaluate the efficacy of BELVIQ with respect to glycemic control in patients with type 2 diabetes mellitus.

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 dependence.
