Arena Pharmaceuticals, Inc. : Arena Pharmaceuticals Announces Eisai's Submission of BELVIQ® (lorcaserin HCl) Marketing Authorization Application in Mexico

04/01/2013 | 08:05am EDT

SAN DIEGO, April 1, 2013 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) announced today that Eisai Laboratorios S. de R.L. de C.V., a subsidiary of Eisai Inc., has submitted a marketing authorization application (MAA) for BELVIQ(® )(lorcaserin HCl) in Mexico with the Federal Commission for the Protection Against Sanitary Risk (COFEPRIS). The intended indication for BELVIQ is 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/m(2) or greater (obese), or 27 kg/m(2) or greater (overweight) in the presence of at least one weight-related comorbid condition. Based on the MAA submission, Arena will receive a milestone payment of $500,000 from Eisai.

"We look forward to the opportunity to help address this unmet medical need by bringing BELVIQ to patients in Mexico who can benefit from treatment for chronic weight management," said Jack Lief, Arena's President and Chief Executive Officer. "We plan to commercialize BELVIQ globally through collaborations with organizations such as Eisai that are committed to and have proven capabilities in serving patients and physicians."

Approximately 30 percent of adults in Mexico are obese and 70 percent are overweight or obese. The rapidly increasing prevalence of overweight and obese patients is leading to a large health and economic burden in Mexico.

"Eisai is committed to keeping patients' medical needs at the forefront of all that we do, as part of our human health care corporate mission," said Frank Ciriello, Senior Vice President, Eisai Inc. "We believe that Eisai has an opportunity with BELVIQ to bring a new medical option to help address the needs of patients affected by overweight and obesity in Mexico."

Eisai is responsible for the regulatory approval and, ultimately, marketing and distribution of BELVIQ in Mexico. Subject to approval, Arena will manufacture BELVIQ at its facility in Switzerland and sell finished commercial product to Eisai for distribution in Mexico. Arena is eligible to receive payments based upon Eisai's net sales of BELVIQ and is also eligible to receive regulatory and development milestone payments.

Beyond Mexico, Eisai has marketing and distribution rights in most of North and South America and also plans to submit MAAs for BELVIQ in Canada and Brazil this year. In addition, Arena has granted marketing and distribution rights to Ildong Pharmaceutical Co., Ltd., for South Korea and plans to enter into additional collaborations to commercialize BELVIQ outside of these territories. Arena has composition of matter patents for BELVIQ issued in major jurisdictions globally that, in most cases, are capable of continuing into 2023, and has filed applications for patent extension in the United States, which, if granted, will extend the patent term for BELVIQ into 2026.

About BELVIQ(®) (lorcaserin HCl)

BELVIQ (pronounced "BEL-VEEK") is believed to decrease food consumption and promote satiety by selectively activating serotonin 2C receptors in the brain. Activation of these receptors may help a person eat less and feel full after eating smaller amounts of food. The exact mechanism of action of BELVIQ is not known.

BELVIQ currently is not available. BELVIQ is approved by the US Food and Drug Administration to be used along with a reduced-calorie diet and increased physical activity for chronic weight management in adult patients with an initial BMI of:

    --  30 kg/m(2) or greater (obese), or
    --  27 kg/m(2) 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

BELVIQ will be available in the United States only after Drug Enforcement Agency (DEA) scheduling is effective. The DEA has published a notice in the Federal Register recommending that BELVIQ be classified as a Schedule IV controlled substance, and BELVIQ is currently awaiting final scheduling designation.



    --  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 (eg, 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
    --  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 (eg, sickle cell anemia, multiple myeloma, or leukemia), or in
        men with anatomical deformation of the penis (eg, 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

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%).

Nursing Mothers

    --  BELVIQ should not be taken by women who are nursing.
