Arena Pharmaceuticals  
Arena制藥公司是一家生物制藥公司發現，開發和商品化的藥物，在治療領域的心血管疾病，中樞神經系統，炎癥和代謝性疾病的重點。該公司正在開發一種化合物，這種行為稱為G蛋白偶聯受體的藥物靶標，使用其專利技術，其中包括組成物激活受體技術和黑色素的管道。競技場的產品包括APD811，第二階段的臨床試驗5-HT2C5 - 羥色胺受體激動劑，其將被用于治療肥胖和APD334，I期臨床試驗的產品，用于治療失眠，使用。其研究和發展計劃還包括APD597，APD916，APD791和APD125，所有這一切都是口頭的候選藥物。該公司始建于1997年4月由Dominic P.貝安和杰克·利夫和總部設在加利福尼亞州圣迭戈。

Our Focus
We are a clinical-stage biopharmaceutical company focused on discovering, developing and commercializing oral drugs that target G protein-coupled receptors, or GPCRs, an important class of validated drug targets, in four major therapeutic areas: cardiovascular, central nervous system, inflammatory and metabolic diseases.
Our Research & Development Pipeline
Lorcaserin is our most advanced investigational drug candidate and is intended for weight management, including weight loss and maintenance of weight loss. In October 2010, the US Food and Drug Administration, or FDA, issued a Complete Response Letter, or CRL, with respect to the lorcaserin New Drug Application, or NDA, we submitted in December 2009. In the CRL, the FDA stated that it completed its review of the NDA and determined that it could not approve the application in its then present form.
After completing various studies, analyses and other activities in response to the lorcaserin CRL, in December 2011, we resubmitted the lorcaserin NDA. The FDA accepted the resubmission for filing and review and assigned a new Prescription Drug User Fee Act, or PDUFA, target date of June 27, 2012.
The FDA’s Endocrinologic and Metabolic Drugs Advisory Committee met on May 10, 2012, to discuss the lorcaserin NDA. The advisory committee voted 18 to 4, with one abstention, that the available data demonstrate that the potential benefits of lorcaserin outweigh the potential risks when used long-term in a population of overweight and obese individuals.
We are also seeking regulatory approval for lorcaserin in the European Union. On March 2, 2012, we filed a marketing authorization application, or MAA, for lorcaserin through the centralized procedure with the European Medicines Agency, or EMA, and the EMA subsequently accepted the filing. The acceptance of the MAA filing begins the EMA’s review process.
In addition to lorcaserin, our prioritized earlier-stage programs include APD811, an internally discovered, orally available agonist of the prostacyclin receptor intended for the treatment of pulmonary arterial hypertension; APD334, an internally discovered, orally available agonist of the S1P1 receptor intended for the treatment of a number of conditions related to autoimmune diseases, including multiple sclerosis; APD371, an internally discovered, orally available agonist of the cannabinoid receptor 2 intended for the treatment of pain; and GPR119 agonists, intended for the treatment of type 2 diabetes. Our internally discovered, oral drug candidates also include temanogrel, which was formerly called APD791 and is intended for the treatment of arterial thrombosis and other related conditions, and nelotanserin, which we previously studied for insomnia and was formerly called APD125.
Our Strategy
The key elements of our general strategy are as follows:
Focus on lorcaserin. We intend to focus our efforts on seeking approval for lorcaserin in the United States, the European Union and other select markets outside of the United States. Pending regulatory approvals, we intend to commercialize lorcaserin in the United States under our marketing and supply agreement with Eisai and in other markets with one or more collaborators or independently.
Selectively advance our other lead candidates. We intend to selectively advance our pipeline of drug candidates independently or through licensing, collaborations or other opportunities.
Maintain research and development capabilities to advance our pipeline. Our technologies, our drug discovery infrastructure and the integrated approach to research used by our scientists have allowed us to identify and develop a number of GPCR targets and novel compounds, and our development infrastructure has allowed us to develop compounds through NDA filing. We expect that our research and development capabilities will continue to play an important role in the support of the further development and potential commercialization of lorcaserin. We intend to maintain our research and development capabilities to selectively advance our programs and to discover additional drug candidates.
