FDA Approves Arena Pharmaceuticals, Inc. Obesity Drug; First in 13 Years

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/m2or 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.

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 for Overweight 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.

Indications

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.
