AstraZeneca's Farxiga Gets CRL From FDA For Type I Diabetes

 | Jul 15, 2019 05:43AM ET

AstraZeneca (NYSE:AZN) announced that the FDA has issued a complete response letter (“CRL”) to its supplemental new drug application (sNDA) for SGLT2 inhibitor, Farxiga (dapagliflozin). The sNDA sought approval for label expansion of Farxiga as an adjunct treatment to insulin to improve glycemic control in type I diabetes patients in whom insulin has inadequate response.

The details of the CRL have not been announced. The company will meet with the FDA to discuss the CRL and seek the path forward for the sNDA. The sNDA was filed based on data from the phase III DEPICT study. Data from the study showed that both the 5mg and 10mg doses of Forxiga led to significant and clinically-meaningful reductions from baseline in average blood glucose levels HbA1c (primary endpoint), weight and total daily insulin dose (secondary endpoints) at 24 weeks.

In March, Forxiga was approved for a similar indication in Europe and Japan. Farxiga/Forxiga is already approved as both monotherapy and combination therapy to improve glycemic control, with additional benefits of weight loss and blood pressure reduction as an adjunct to diet and exercise in adults with type-II diabetes.

Please note that, in March, the FDA also issued a CRL to Lexicon Pharmaceuticals, Inc.’s (NASDAQ:LXRX) new drug application seeking approval for Zynquista, a dual SGLT1 and SGLT2 inhibitor, in combination with insulin as a treatment for type I diabetes. The details of the CRL were not available. Lexicon is developing the candidate in collaboration with Sanofi (NASDAQ:SNY) .

It may seem that SGLT inhibitors have adequate response in type II diabetes patients. However, these face some hurdles in type I diabetes patients. It has been observed that SGLT inhibitors carry the risk of diabetic ketoacidosis, a serious complication of diabetes. In both CRLs, the concerned companies are working with the FDA to sort out any issues. There is no approved SGLT inhibitor for type I diabetes in the United States.

AstraZeneca’s stock has increased 5.8% this year so far, outperforming the industry ’s decrease of 1.6%.
