WOODCLIFF LAKE, N.J., June 21, 2017 /PRNewswire/ -- Eisai Inc. today announced that the ongoing investigational CAMELLIA-TIMI 61 study of lorcaserin (marketed as BELVIQ® CIV) will continue as planned, based on the recommendation of an independent Data Monitoring Committee (DMC) after it completed a pre-specified interim safety analysis evaluating the incidence of MACE events, defined as cardiovascular death, myocardial infarction or stroke. The DMC will continue to monitor the ongoing safety of lorcaserin as planned.
The five-year study, comprised of 12,000 patients, is being conducted in partnership with the Thrombolysis in Myocardial Infarction (TIMI) Study Group and is intended to address the post-marketing requirement from the U.S. Food and Drug Administration to evaluate the long-term cardiovascular safety of lorcaserin.
The study is expected to conclude in 2018.
BELVIQ is indicated 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, dyslipidemia, type 2 diabetes). The safety and efficacy of coadministration of BELVIQ with other products intended for weight loss including prescription drugs (e.g., phentermine), over-the-counter drugs, and herbal preparations have not been established, nor has the effect of BELVIQ on cardiovascular morbidity and mortality.
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 efficacy objective is to evaluate the impact of lorcaserin on the incidence of MACE+, defined as MACE or hospitalization due to unstable angina or heart failure, or any coronary revascularization. In addition, other secondary objectives include the evaluation of lorcaserin on glycemic control in patients with type 2 diabetes mellitus and the potential to delay or prevent the conversion from pre-diabetes to type 2 diabetes.
The effect of BELVIQ on cardiovascular morbidity has not been established. BELVIQ is not approved for use in the delay or prevention of diabetes.
IMPORTANT SAFETY INFORMATION
- BELVIQ should not be taken during pregnancy or by women who are planning to become pregnant.
- Patients with prior hypersensitivity reactions to lorcaserin or to any of the product components should not take this medicine. Hypersensitivity reactions have been reported.
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 Neuroleptic malignant syndrome (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%).
- 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.
Obesity is a serious and growing public health issue. The prevalence of obesity in the U.S. has more than doubled among adults in the past 30 years. Approximately 69 percent of American adults over the age of 20 are affected by obesity and overweight. This dramatic rise in obesity has also had a major impact on other diseases.
