BELVIQ will be available to patients by prescription in US pharmacies beginning June 11. Eisai Inc. is responsible for the marketing and distribution of BELVIQ under its agreement with Arena Pharmaceuticals GmbH, a wholly owned subsidiary of Arena Pharmaceuticals, Inc.
BELVIQ is approved by the US Food and Drug Administration for use 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.
"Our team discovered and developed BELVIQ with the goal of providing physicians with a new tool to help fight the global obesity epidemic," said Dominic P. Behan, Ph.D., Arena's Executive Vice President and Chief Scientific Officer. "We are proud to provide physicians in the United States with a new treatment option that along with diet and exercise can help committed patients effectively manage their weight."
Arena manufactures BELVIQ at its facility in Switzerland, and sells finished commercial product to Eisai for a purchase price starting at 31.5% of Eisai's annual net product sales. The purchase price increases on a tiered basis up to 36.5% on the portion of annual net product sales exceeding $750 million. In connection with the US launch of BELVIQ, Arena has achieved $65 million in milestones from Eisai. Arena is also eligible to receive $1.19 billion in purchase price adjustment and other payments based on Eisai's annual net sales levels of BELVIQ.
"BELVIQ is the product of our vision and commitment to bring novel treatments to physicians and patients for unmet medical needs," said Jack Lief, Arena's President and Chief Executive Officer. "Our collaboration with Eisai is an integral component of the strong foundation we have in place to make BELVIQ available to eligible patients."
Arena's marketing and supply agreement with Eisai covers most of North and South America. Eisai has submitted a marketing authorization application for BELVIQ in Mexico, and plans to submit applications for the approval of BELVIQ in Canada and Brazil this year. Arena also has a BELVIQ marketing and supply agreement with Ildong Pharmaceutical Co., Ltd., for South Korea, and Ildong plans to submit an application for the approval of BELVIQ in South Korea around the end of this year. Arena plans to enter into additional collaborations to support the commercialization of BELVIQ in other territories.
Composition of matter patents for BELVIQ are issued in major jurisdictions globally that, in most cases, are capable of continuing into 2023. Arena has filed applications for patent extension in the United States, which, if granted, will extend the patent term for BELVIQ into 2026.

IMPORTANT SAFETY INFORMATION
- 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%).
- BELVIQ should not be taken by women who are nursing.
