Efficacy at Year 1: BELVIQ® 10 mg Twice Daily

Patients taking BELVIQ® ACHIEVED AND SUSTAINED CLINICALLY SIGNIFICANT WEIGHT LOSS at Year 1 (MITT population)*

  • Response to therapy should be evaluated by Week 12. If a patient has not lost at least 5% of baseline body weight, discontinue BELVIQ® or BELVIQ XR®, as it is unlikely that the patient will achieve and sustain clinically meaningful weight loss with continued treatment. If a patient has lost 5% of baseline body weight by Week 12, continuation of treatment may be considered among other factors

Patients taking BELVIQ® showed WEIGHT LOSS AT WEEK 2 (MITT population)2

  • At the 2-week visit, patients taking BELVIQ® (N=2918) lost an average of 3.3 lbs vs 2.0 lbs for those taking placebo (N=2865) (part of the preplanned analysis)

* Modified intent-to-treat population (MITT) using last observation carried forward (LOCF) method; all patients who received study medication and had a postbaseline body weight measurement. Pooled BLOOM/BLOSSOM trials: 44% of patients taking BELVIQ® and 51% of patients taking placebo withdrew prior to Week 52. Mean baseline body weight: BELVIQ® (100.4 kg/221.3 lb) and placebo (100.2 kg/220.9 lb).

Material limitations: Not adjusted for multiplicity or adequately powered to show statistical significance.

Patients taking BELVIQ® who achieved 5% weight loss LOST AN AVERAGE OF 24 LBS (ranging from 8 lbs to 82 lbs)§

§BELVIQ® (n=1562); patients who achieved 5% weight loss with placebo (n=729) lost an average of 23 lbs (ranging from 8 lbs to 124 lbs).

†For those who achieved 5% and 10% weight loss, 1 patient lost 80-90 lbs with BELVIQ®.
‡For those who achieved 5% and 10% weight loss, 1 patient lost 120-130 lbs, 1 lost 90-100 lbs, and 1 lost 80-90 lbs with placebo.

INDICATION

BELVIQ/BELVIQ XR 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).

Limitations of Use:

  • The safety and efficacy of coadministration of BELVIQ/BELVIQ XR 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/BELVIQ XR on cardiovascular morbidity and mortality has not been established.

IMPORTANT SAFETY INFORMATION

Contraindications

  • Pregnancy: BELVIQ/BELVIQ XR should not be taken during pregnancy or by women who are planning to become pregnant.
  • Hypersensitivity: Patients with prior hypersensitivity reactions to lorcaserin or to any of the product components should not take BELVIQ/BELVIQ XR. Hypersensitivity reactions have been reported.

Warnings and Precautions

  • Serotonin Syndrome or Neuroleptic Malignant Syndrome (NMS)- like reactions: BELVIQ/BELVIQ XR 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/BELVIQ XR and any concomitant serotonergic or antidopaminergic agents should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated.
  • Valvular heart disease: Patients should not take BELVIQ/BELVIQ XR in combination with potent 5-HT2B receptor agonists that have been associated with regurgitant 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 were symptomatic. BELVIQ/BELVIQ XR 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/BELVIQ XR should be considered.
  • Cognitive impairment: 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/BELVIQ XR affects them.
  • Psychiatric disorders: The recommended daily dose 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/BELVIQ XR in patients who develop suicidal thoughts or behaviors.
  • Hypoglycemia: 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/BELVIQ XR is recommended. Decreases in doses of antidiabetic medications or changes in medication regimen should be considered.
  • Priapism: Men who experience priapism should immediately discontinue BELVIQ/BELVIQ XR and seek emergency medical attention. BELVIQ/BELVIQ XR should be used with caution with erectile dysfunction medications. BELVIQ/BELVIQ XR 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).
  • Heart rate decreases: Because BELVIQ/BELVIQ XR 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.
  • Monitoring Considerations: Consider monitoring for CBC changes, signs and symptoms of prolactin excess, and pulmonary hypertension.

Most Common Adverse Reactions for BELVIQ®

  • 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%).

Most Common Adverse Reactions for BELVIQ XR®

Nursing Mothers

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