Arena Submits Response to FDA Complete Response Letter for Lorcaserin
SAN DIEGO and WOODCLIFF LAKE, N.J., Jan. 3, 2012 /PRNewswire/ -- Arena Pharmaceuticals, Inc. and Eisai Inc. announced today that Arena has submitted its response to the Complete Response Letter (CRL) issued by the US Food and Drug Administration (FDA) following review of the lorcaserin New Drug Application (NDA). Lorcaserin is intended for weight management, including weight loss and maintenance of weight loss, in patients who are obese (Body Mass Index, or BMI, >30) or patients who are overweight (BMI >27) and have at least one weight-related co-morbid condition. The companies expect that later this month the FDA will confirm acceptance of the response and assign a new Prescription Drug User Fee Act (PDUFA) date.
"We have worked diligently with Eisai to prepare this submission that we believe will address the issues raised in the complete response letter," said Jack Lief, Arena's President and Chief Executive Officer. "We look forward to providing on today's call an overview of the submission contents, including the results of the recently completed rat mechanistic studies, which we believe provide additional data supporting lorcaserin's benefit-risk profile."
Lonnel Coats, President and Chief Executive Officer of Eisai Inc., said, "Weight loss for obese patients and overweight patients with co-morbid conditions remains an area of unmet need. Eisai is pleased to collaborate with Arena in its response to the FDA, an important milestone toward lorcaserin's potential approval."
The response to the lorcaserin CRL includes data and analyses that were not incorporated in the original NDA, including the results of Arena's Phase 3 BLOOM-DM (Behavioral modification and Lorcaserin for Overweight and Obesity Management in Diabetes Mellitus) clinical trial, which evaluated lorcaserin for weight loss in patients with type 2 diabetes. The new information also includes data and analyses from activities intended to address tumors observed in a two-year lorcaserin rat carcinogenicity study, cell culture experiments intended to further refine serotonin subtype 2 receptor activity and rat studies designed to further assess abuse potential. It is important to note that the FDA may analyze or weigh the data differently than Arena and Eisai.
Lorcaserin is an investigational drug candidate intended for weight management, including weight loss and maintenance of weight loss, in patients who are obese (BMI >30) or patients who are overweight (BMI >27) and have at least one weight-related co-morbid condition. Lorcaserin is a new chemical entity that is believed to act as a selective serotonin 2C receptor agonist. The serotonin 2C receptor is expressed in the brain, including the hypothalamus, an area believed to be involved in the control of appetite and metabolism. Arena has patents that cover lorcaserin in the United States and other jurisdictions that in most cases are capable of continuing into 2023 without taking into account any patent term extensions or other exclusivity Arena might obtain.
Arena submitted the original NDA for lorcaserin in December 2009, and the FDA issued a CRL in October 2010. Arena submitted a response to the lorcaserin CRL in December 2011, and it expects that in January 2012 the FDA will assign a new PDUFA date. Arena's wholly owned subsidiary, Arena Pharmaceuticals GmbH, has granted Eisai Inc. exclusive rights to market and distribute lorcaserin in the United States subject to FDA approval of the lorcaserin NDA.
Lorcaserin Phase 3 Clinical Trial Program Overview
The lorcaserin Phase 3 clinical trial program consists of three double-blind, randomized, placebo-controlled trials, BLOOM (Behavioral modification and Lorcaserin for Overweight and Obesity Management), BLOSSOM (Behavioral modification and LOrcaserin Second Study for Obesity Management) and BLOOM-DM, and enrolled approximately 7,800 patients. BLOOM and BLOSSOM evaluated lorcaserin versus placebo in patients who are obese or patients who are overweight and have at least one weight-related co-morbid condition. BLOOM evaluated 3,182 patients over a two-year treatment period, and BLOSSOM evaluated 4,008 patients over a one-year treatment period. BLOOM-DM evaluated 604 obese and overweight patients with type 2 diabetes over a one-year treatment period. The trials included a standardized program of moderate diet and exercise guidance.
