Eisai Inc. and Arena Pharmaceuticals, Inc. Complete Registrational Trials of an Extended Release Formulation of Lorcaserin

Eisai Inc. and Arena Pharmaceuticals, Inc. 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 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. 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 immediate release or 20 mg once-daily 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.

Arena Pharmaceuticals, Inc. Reports Unaudited Consolidated Earnings Results for the Fourth Quarter and Full Year Ended December 31, 2014; Provides Earnings Guidance for the Full Year of 2015

Arena Pharmaceuticals, Inc. reported unaudited consolidated earnings results for the fourth quarter and full year ended December 31, 2014. For the quarter, the company reported net loss of $32.1 million, or $0.15 loss per diluted share, compared with the prior-year period's $23.5 million or $0.11 loss per diluted share. Total revenue was $9.2 million, up from $6.5 million in the same quarter last year. For the year, the company reported net loss of $60.51 million against $19.43 million a year ago. Diluted loss per share was $0.28 against $0.09 a year ago. Total revenue was $36.97 million against $81.39 million a year ago. 2013 revenues were higher than 2014 revenues, primarily because in 2013, the company earned $65 million of milestone payments from Eisai in connection with the final scheduling destination for BELVIQ. The company said that for 2015, it expects majority of its revenues to be payments from collaborators based on their net product sales of BELVIQ. ARNA expects to receive 31.5% and 35% of Eisai's and Ildong's net product sales of BELVIQ, respectively. Arena is currently not able to predict the amount of these sales and, accordingly, is not providing guidance for its overall 2015 revenues at this time. A lesser amount of Arena’s total 2015 revenues will consist of regulatory milestones (including the $3.0 million milestone achieved from the approval of BELVIQ in South Korea in February 2015), amortization of upfront payments from existing collaborations (expected to be approximately $8.0 million), development and patent reimbursements from Eisai (expected to be approximately $7.0 million), and toll manufacturing from Siegfried (expected to be approximately $1.0 million). The company expects full year 2015 research and development expenses of approximately $114.0 million to $122.0 million, including non-cash expenses of approximately $13.0 million and $6.0 million in development expenses reimbursed by Eisai (with such reimbursed expenses included in revenue). In addition, the company expects to spend approximately $8.0 million to $9.0 million for capital expenditures, primarily related to its manufacturing facility in Switzerland. Arena may moderate its planned level of expenses based on its revenues and shared costs with collaborators.
