AZ nabs 6 more months of Symbicort exclusivity—and the sales that come with it

AstraZeneca won pediatric exclusivity for its respiratory blockbuster Symbicort, extending its protection from generic rivals.

AstraZeneca’s aging respiratory giant Symbicort won a coveted pediatric exclusivity nod from the FDA on Wednesday, giving the brand a longer life—and potentially hundreds of millions in additional sales before generics hit.

By winning pediatric exclusivity, Symbicort will have 6 months of protection in each of its indications added to the end of its patent life, meaning two quarters of extra branded sales in the U.S. The drug brought in $277 million for AZ in the U.S. in the third quarter of 2016, while worldwide sales for the period were $697 million.

The pediatric exclusivity nod is based on Symbicort trials in children with asthma aged 6 to 12, AstraZeneca said on Thursday. Symbicort is FDA-approved to treat asthma in patients 12 and older and chronic obstructive pulmonary disease (COPD) in adults. The inhaler first won an FDA nod in 2006.

Since turning away that massive Pfizer deal, AstraZeneca has kicked off multiple rounds of job cuts, recently eliminating about 700 positions in its U.S. commercial business. Before that, the company cut 1,600 contract reps and company personnel back in May 2016.
