Eisai and Arena Pharmaceuticals Complete Registrational Trials of an Extended Release Formulation of Lorcaserin
Date:4/10/2015

WOODCLIFF LAKE, N.J. and SAN DIEGO, Calif., April 10, 2015 /PRNewswire/ -- Eisai Inc. and Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) today announced the completion of two Phase 1 registrational clinical trials that Eisai and Arena believe demonstrate bioequivalence of an investigational once-daily extended release formulation of lorcaserin, as compared to the twice-daily immediate release formulation approved by the US Food and Drug Administration (FDA) and marketed as BELVIQ®. If approved, the extended release formulation is expected to be marketed as BELVIQ XR, which is the brand name conditionally approved by the FDA.

"This extended release formulation has the potential to offer once-daily dosing," said Jack Lief, Arena's President and Chief Executive Officer. "We expect the results from these trials will allow us to submit a New Drug Application with the FDA for the treatment of weight management later this year and may also support our efforts to further pursue additional opportunities within our lorcaserin lifecycle management portfolio."

Each of the two randomized, crossover trials evaluated the safety, tolerability, pharmacokinetics and bioavailability of an extended release formulation of lorcaserin in 36 healthy adult subjects. Patients in each trial were divided into two treatment groups and received both doses in a two-way crossover sequence. Patients in the first study were dosed under fasted conditions either 10 mg twice-daily (BID) immediate release or 20 mg once-daily (QD) extended release. Patients in the second study were dosed either 20 mg QD extended release in the fasted state or 20 mg QD extended release in the fed state.

The most common treatment-emergent adverse events were similar to those seen in the Phase 3 clinical trials of BELVIQ, and included mild or moderate headache, constipation, dizziness and nausea. There were no discontinuations for adverse events, and no serious adverse events were observed.

Lorcaserin extended release formulation is investigational and not approved by any regulatory agency.

About BELVIQ® (lorcaserin HCl) CIVImmediate-release lorcaserin is approved under the brand name BELVIQ for weight management by the FDA and the Ministry of Food and Drug Substances in South Korea. Eisai Inc. and Ildong Pharmaceutical Co., Ltd., market and distribute BELVIQ in the United States and South Korea, respectively, and Arena manufactures and supplies the finished commercial product from its facility in Switzerland.

BELVIQ is a serotonin 2C receptor agonist indicated in the United States as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults who have a body mass index (BMI) of 30 kg/m2 or greater (obese), or BMI of 27 kg/m2 or greater (overweight) with at least one weight-related medical condition, such as high blood pressure, high cholesterol, or type 2 diabetes. 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 InformationContraindication

  • 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 were 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 (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 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%).
  • Nursing Mothers

  • BELVIQ should not be taken by women who are nursing.
  • BELVIQ® is a federally controlled substance that may lead to abuse or dependence.
