The FDA announced today that it had approved its first new weight loss drug in 13 years. Lorcaserin, which will be sold under the brand name of Belviq, is manufactured by Arena Pharmaceuticals and will be distributed in the US by Eisai.
Lorcaserin is indicated for use in obese adults (BMI 30 or above) or overweight adults (BMI 27 or above) with a coexisting weight-related condition such as hypertension, diabetes, or high cholesterol.
“Obesity threatens the overall well being of patients and is a major public health concern,” said the FDA’s Janet Woodcock, in an FDA press release. “The approval of this drug, used responsibly in combination with a healthy diet and lifestyle, provides a treatment option for Americans who are obese or are overweight and have at least one weight-related comorbid condition.”
The FDA is requiring Arena to conduct six postmarketing studies, including a long-term CV outcomes trial. The label will note that the effect of lorcaserin on cardiovascular morbidity and mortality have not been established and that its safety and efficacy when used with other weight loss drugs has not been tested.
Arena said that the FDA has recommended to the Drug Enforcement Administration (DEA) that lorcaserin be classified as a scheduled drug. The drug will not be available until after the DEA reviews the recommendation and decides whether the drug will be scheduled. During a press conference the company said that DEA scheduling normally takes from four to six months, indicating that the drug might not become available this year.
Here is the FDA press release:
|FDA approves Belviq to treat some overweight or obese adults
|The U.S. Food and Drug Administration today approved Belviq (lorcaserin hydrochloride), as an addition to a reduced-calorie diet and exercise, for chronic weight management.
The drug is approved for use in adults with a body mass index (BMI) of 30 or greater (obese), or adults with a BMI of 27 or greater (overweight) and who have at least one weight-related condition such as high blood pressure (hypertension), type 2 diabetes, or high cholesterol (dyslipidemia).
BMI, which measures body fat based on an individual’s weight and height, is used to define the obesity and overweight categories. According to the Centers for Disease Control and Prevention, more than one-third of adults in the United States are obese.
“Obesity threatens the overall well being of patients and is a major public health concern,” said Janet Woodcock, M.D., director of the FDA’s Center for Drug Evaluation and Research. “The approval of this drug, used responsibly in combination with a healthy diet and lifestyle, provides a treatment option for Americans who are obese or are overweight and have at least one weight-related comorbid condition.”
Belviq works by activating the serotonin 2C receptor in the brain. Activation of this receptor may help a person eat less and feel full after eating smaller amounts of food.
The safety and efficacy of Belviq were evaluated in three randomized, placebo-controlled trials that included nearly 8,000 obese and overweight patients, with and without type 2 diabetes, treated for 52 to 104 weeks. All participants received lifestyle modification that consisted of a reduced calorie diet and exercise counseling. Compared with placebo, treatment with Belviq for up to one year was associated with average weight loss ranging from 3 percent to 3.7 percent.
About 47 percent of patients without type 2 diabetes lost at least 5 percent of their body weight compared with about 23 percent of patients treated with placebo. In people with type 2 diabetes, about 38 percent of patients treated with Belviq and 16 percent treated with placebo lost at least 5 percent of their body weight. Belviq treatment was associated with favorable changes in glycemic control in those with type 2 diabetes. The approved labeling for Belviq recommends that the drug be discontinued in patients who fail to lose 5 percent of their body weight after 12 weeks of treatment, as these patients are unlikely to achieve clinically meaningful weight loss with continued treatment.
Belviq should not be used during pregnancy. Treatment with Belviq may cause serious side effects, including serotonin syndrome, particularly when taken with certain medicines that increase serotonin levels or activate serotonin receptors. These include, but are not limited to, drugs commonly used to treat depression and migraine. Belviq may also cause disturbances in attention or memory.
In 1997, the weight-loss drugs fenfluramine and dexfenfluramine were withdrawn from the market after evidence emerged that they caused heart valve damage. This effect is assumed to be related to activation of the serotonin 2B receptor on heart tissue. When used at the approved dose of 10 milligrams twice a day, Belviq does not appear to activate the serotonin 2B receptor.
Heart valve function was assessed by echocardiography in nearly 8,000 patients in the Belviq development program. There was no statistically significant difference in the development of FDA-defined valve abnormalities between Belviq and placebo-treated patients. Because preliminary data suggest that the number of serotonin 2B receptors may be increased in patients with congestive heart failure, Belviq should be used with caution in patients with this condition. Belviq has not been studied in patients with serious valvular heart disease.
The drug’s manufacturer will be required to conduct six postmarketing studies, including a long-term cardiovascular outcomes trial to assess the effect of Belviq on the risk for major adverse cardiac events such as heart attack and stroke.
The most common side effects of Belviq in non-diabetic patients are headache, dizziness, fatigue, nausea, dry mouth, and constipation, and in diabetic patients are low blood sugar (hypoglycemia), headache, back pain, cough, and fatigue.
Belviq is manufactured by Arena Pharmaceuticals GmbH of Zofingen, Switzerland, and distributed by Eisai Inc. of Woodcliff Lake, N.J.

Arena Pharmaceuticals and Eisai Announce FDA Approval of BELVIQ® (lorcaserin HCl) for Chronic Weight Management in Adults who are Overweight with a Comorbidity or Obese
– First Prescription Weight-Loss Treatment Approved by FDA in 13 Years –
– Eisai to Launch BELVIQ in U.S. Following DEA’s Completion of Scheduling Review –
SAN DIEGO and WOODCLIFF LAKE, N.J., June 27, 2012 /PRNewswire/ – Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) and Eisai Inc. announced today that the U.S. Food and Drug Administration (FDA) has approved BELVIQ (pronounced BEL-VEEK) as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adult patients 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 indication includes the following limitations of use: The safety and efficacy of coadministration of BELVIQ with other products intended for weight loss and the effect of BELVIQ on cardiovascular morbidity and mortality have not been established.
“The FDA approval of BELVIQ is an important development for patients who struggle with obesity or are overweight with comorbidities and need help with chronic weight management beyond diet and exercise,” said Jack Lief, Arena’s President and Chief Executive Officer. “We thank our entire team and the patients who participated in our clinical trial program for making this achievement possible.”
Three double-blind, randomized, placebo-controlled trials demonstrated that BELVIQ along with diet and exercise was more effective than diet and exercise alone at helping patients lose 5% or more of their body weight after one year and managing the weight loss for up to two years.
“Diet, exercise and behavioral therapy alone may not result in sustained weight loss for many overweight and obese people trying to lose weight,” said Lonnel Coats, President and Chief Executive Officer, Eisai Inc. “BELVIQ represents an important therapeutic option for physicians responsible for the medical management of their patients who are overweight or obese.”
In clinical trials, the most common adverse reactions for patients without diabetes treated with BELVIQ were headache, dizziness, fatigue, nausea, dry mouth, and constipation. In patients with diabetes, the most common adverse reactions were hypoglycemia, headache, back pain, cough, and fatigue.
The FDA has recommended that BELVIQ be classified by the U.S. Drug Enforcement Administration (DEA) as a scheduled drug. The DEA will review the FDA’s recommendation and determine the final scheduling designation. Once the DEA has provided the final scheduling designation, Eisai will announce when BELVIQ will be available to patients and physicians in the United States.
Arena will manufacture and supply the finished commercial product from its facility in Switzerland, and Eisai will market and distribute BELVIQ in the United States.
As part of the approval of BELVIQ, the companies committed to conduct post-marketing studies to assess the safety and efficacy of BELVIQ for weight management in obese pediatric patients, as well as to evaluate the effect of long-term treatment with BELVIQ on the incidence of major adverse cardiovascular events in overweight and obese subjects with cardiovascular disease or multiple cardiovascular risk factors. The cardiovascular outcomes trial will include echocardiographic assessments.

About BELVIQ (lorcaserin HCl)
BELVIQ (lorcaserin hydrochloride) is believed to decrease food consumption and promote satiety by selectively activating serotonin 2C receptors in the brain.
BELVIQ Phase 3 Clinical Trial Program
The BELVIQ Phase 3 clinical trial program consisted of three double-blind, randomized, placebo-controlled trials: BLOOM (Behavioral modification and Lorcaserin forOverweight and Obesity Management), BLOSSOM (Behavioral modification and LOrcaserin Second Study for Obesity Management) and BLOOM-DM (Behavioral modification and Lorcaserin for Overweight and Obesity Management in Diabetes Mellitus). All three trials included a standardized program of diet, moderate exercise and behavioral counseling for both the placebo and BELVIQ groups.
BLOOM evaluated BELVIQ versus placebo over a two-year treatment period in 3,182 non-diabetic, obese (BMI of 30 to 45 kg/m2) adult patients (18 to 65 years old) with or without comorbid conditions and non-diabetic, overweight (BMI of 27 to 29.9 kg/m2) adult patients with at least one weight related comorbid condition.
BLOSSOM evaluated BELVIQ versus placebo over a one-year treatment period in 4,008 non-diabetic, obese (BMI of 30 to 45 kg/m2) adult patients (18 to 65 years old) with or without comorbid conditions and non-diabetic, overweight (BMI of 27 to 29.9 kg/m2) adult patients with at least one weight related comorbid condition.
BLOOM-DM evaluated BELVIQ versus placebo over a one-year treatment period in 604 obese (BMI of 30 to 45 kg/m2) and overweight (BMI of 27 to 29.9 kg/m2) adult patients (18 to 65 years old) with type 2 diabetes who were receiving oral antihyperglycemic agents.
BELVIQ is indicated to be used along with a reduced-calorie diet and increased physical activity for chronic weight management in adult patients 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)
Limitations of Use:
- 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
- The effect of BELVIQ on cardiovascular morbidity and mortality has not been established
Important Safety Information
- Pregnancy: BELVIQ should not be taken during pregnancy or by women who are planning to become pregnant.
- Nursing: BELVIQ should not be taken while breastfeeding.
- Serotonin Syndrome or Neuroleptic Malignant Syndrome (NMS)-like Reactions: BELVIQ and certain medicines for depression, migraine, the common cold, and mood, anxiety, psychotic or thought disorders or other medical problems may affect each other causing serious or life-threatening side effects. Patients should tell their doctor if they are taking medicines to treat any of these conditions such as: triptans, tricyclics, lithium, selective serotonin uptake inhibitors (SSRIs), selective serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), or antipsychotics; linezolid, an antibiotic; tramadol; dextromethorphan, an over-the-counter medicine used to treat the common cold or cough; over-the-counter supplements such as tryptophan or St. John’s Wort. BELVIQ and these medicines should be discontinued immediately and symptomatic treatment measures should be initiated if patients taking BELVIQ and these other medicines experience any of the following: mental changes such as agitation, hallucinations, confusion, or other changes in mental status; coordination problems, uncontrolled muscle spasms, or muscle twitching (overactive reflexes); restlessness; racing or fast heartbeat, high or low blood pressure; sweating or fever; nausea, vomiting, or diarrhea; or muscle rigidity (stiff muscles).
- Valvular Heart Disease: Certain weight loss drugs have been associated with problems with the valves in the heart. Patients taking BELVIQ who have trouble breathing, swelling of the arms, legs, ankles, or feet, dizziness, fatigue, or weakness that will not go away, or fast or irregular heartbeat should call their doctor right away. Before taking BELVIQ, patients should tell their doctor if they have or had heart problems including congestive heart failure, or heart valve problems. Patients should not take BELVIQ in combination with drugs that have been associated with valvular heart disease (such as cabergoline). Patients who develop signs and symptoms of valvular heart disease while taking BELVIQ should be evaluated and discontinuation of BELVIQ should be considered by their doctor.
- Changes in Attention or Memory: Problems with thinking, sleepiness, confusion, and fatigue have been reported in patients taking BELVIQ.
- Patients taking BELVIQ should not drive a car or operate heavy machinery until they know how BELVIQ affects them.
- Mental Problems: Taking BELVIQ at higher than the recommended dose may cause psychiatric problems such as: hallucinations, feeling high or in a very good mood (euphoria), feelings of standing next to yourself or out of your body (disassociation). The recommended dose of 10 mg twice daily should not be exceeded. Patients should be monitored for the development or worsening of depression, suicidal thoughts or behaviors, and/or any changes in mood. BELVIQ should be discontinued if patients develop suicidal thoughts or behaviors.
- Low Blood Sugar (Hypoglycemia): Weight loss can cause low blood sugar in people with type 2 diabetes mellitus who are on medicines to treat it such as metformin, insulin, or sulfonylureas. Blood sugar levels should be monitored for patients who take BELVIQ. Changes to medicines may be needed if low blood sugar develops.
- Painful Erections (Priapism): If patients taking BELVIQ experience an erection lasting more than 4 hours, whether it is painful or not, they should stop using BELVIQ and call their doctor or go to the nearest emergency room right away. BELVIQ should be taken with caution by men who have conditions that might predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia), or in men with a deformed penis. Patients should tell their doctor if they take medicines used to treat erectile dysfunction.
- Slow Heartbeat: BELVIQ may cause a slow heartbeat. Patients taking BELVIQ should tell their doctor if they have a history of a slow heartbeat or heart block.
- Decreases in Blood Cell Count: BELVIQ may cause decreases in red or white blood cell count. A doctor may do tests to check a patient’s blood cell count during treatment with BELVIQ.
- Increase in Prolactin: BELVIQ may increase the amount of a hormone the body makes, called prolactin. Patients taking BELVIQ should tell their doctor if their breasts begin to make milk or have a milky discharge or if their breasts begin to increase in size.
- Increased Pressure in the Arteries of the Lung (Pulmonary Hypertension): Certain weight loss drugs have been associated with the rare but life-threatening side effect of increased pressure in the arteries of the lung. It is unknown if BELVIQ increases the risk for this condition.
- Most Common Adverse Reactions In Non-Diabetic Patients: Headache, dizziness, fatigue, nausea, dry mouth, and constipation.
- Most Common Adverse Reactions in Diabetic Patients: Hypoglycemia, headache, back pain, cough, and fatigue.
- Response to BELVIQ should be evaluated at 12 weeks of treatment to determine if therapy should be discontinued.
