US Food and Drug Administration extends action date for dapagliflozin by three months

Wednesday, 26 October 2011

AstraZeneca and Bristol-Myers Squibb Company announced today that the US Food and Drug Administration (FDA) has extended the action date for dapagliflozin for the treatment of type 2 diabetes by three months. The new Prescription Drug User Fee Act (PDUFA) goal date is 28 January 2012.

In response to an FDA request for additional data on dapagliflozin, Bristol-Myers Squibb and AstraZeneca are submitting data from recently completed and ongoing Phase III clinical trials. This data submission constitutes a major amendment to the original new drug application (NDA) for dapagliflozin.

Dapagliflozin, an inhibitor of the SGLT2 target in the kidney, is under joint development by Bristol-Myers Squibb and AstraZeneca. Dapagliflozin, as an adjunct to diet and exercise, is being investigated to evaluate its safety and its effect on blood sugar levels (glycosylated hemoglobin levels, or HbA1c), in adults with type 2 diabetes, for use as a monotherapy and in combination with other anti-diabetic agents.


About Type 2 Diabetes

The Centers for Disease Control and Prevention (CDC) estimate that approximately one in every 11 adults in the United States has diagnosed diabetes. Type 2 diabetes accounts for approximately 90 to 95% of all cases of diagnosed diabetes in adults. Type 2 diabetes is a chronic, progressive disease characterized by insulin resistance and/or dysfunction of beta cells in the pancreas, which decreases insulin sensitivity and secretion, leading to elevated glucose levels. Over time, this sustained hyperglycemia contributes to worsening insulin resistance and further beta cell dysfunction. To date, treatments for type 2 diabetes have focused primarily on insulin-dependent mechanisms. An approach that acts independently of insulin could provide an additional option for adults with type 2 diabetes.

Significant unmet needs still exist as nearly half of treated patients remain uncontrolled on their current glucose-lowering regimen. Many patients with type 2 diabetes have additional co-morbidities (such as obesity) which may complicate glycemic control.

Bristol-Myers Squibb and AstraZeneca Collaboration

Bristol-Myers Squibb and AstraZeneca entered into a collaboration in January 2007 to enable the companies to research, develop and commercialize select investigational drugs for type 2 diabetes. The Bristol-Myers Squibb/AstraZeneca Diabetes collaboration is dedicated to global patient care, improving patient outcomes and creating a new vision for the treatment of type 2 diabetes.
