(NYSE: AZN) and
Bristol-Myers Squibb Company
(NYSE: BMY) today announced that the U.S. Food and Drug Administration (FDA) has acknowledged receipt of the New Drug Application (NDA) resubmission for investigational drug dapagliflozin for the treatment of adults with type 2 diabetes. The FDA assigned a new Prescription Drug User Fee Act (PDUFA) goal date of Jan. 11, 2014.
The dapagliflozin Phase 2/3 clinical development program included more than 12,000 adult patients with diabetes (more than 8,000 patients received dapagliflozin) in 26 clinical trials. In response to the FDA’s January 2012 complete response letter requesting additional data to allow a better assessment of the benefit-risk profile of dapagliflozin, the NDA resubmission includes several new studies and additional long-term data (up to four years’ duration) from previously submitted studies, resulting in an overall increase in patient-years exposure to dapagliflozin of more than 50 percent.
Dapagliflozin, an investigational compound, is a selective and reversible inhibitor of sodium-glucose cotransporter 2 (SGLT2), which works independently of insulin. It is currently approved for the treatment of type 2 diabetes in the European Union, Australia, Brazil, Mexico and New Zealand.
About SGLT2 Inhibition
The kidney plays an important role in maintaining normal glucose balance by filtering and reabsorbing glucose from circulation. SGLT2, a sodium-glucose cotransporter found predominantly in the kidney, is responsible for approximately 90 percent of glucose reabsorption. In patients with type 2 diabetes, the capacity of the kidney to reabsorb glucose is increased by approximately 20 percent, further exacerbating the hyperglycemia associated with the disease. Selective inhibition of SGLT2 reduces the reabsorption of excess glucose and enables its removal via the urine.
In 2012, diabetes was estimated to affect more than 370 million people worldwide. The prevalence of diabetes is projected to reach more than 550 million by 2030. Type 2 diabetes accounts for approximately 90% to 95% of all cases of diagnosed diabetes in adults. Type 2 diabetes is a chronic disease characterized by insulin resistance and dysfunction of beta cells in the pancreas, leading to elevated glucose levels. Over time, this sustained hyperglycemia contributes to further progression of the disease. Significant unmet needs still exist, as many patients remain inadequately controlled on their current glucose-lowering regimen.
