Novartis Walks Away from Generic Advair
Novartis says it is abandoning its work to gain FDA approval for a generic copy of GlaxoSmithKline’s Advair Diskus (fluticasone propionate/salmeterol). The product is indicated for treating asthma in patients aged four years and older, in addition to providing maintenance treatment of airflow obstruction and reducing exacerbations in patients with chronic obstructive pulmonary disease.
In the company’s just-posted annual report, Novartis says it recently decided to discontinue the generic Advair development program in the U.S., “following a recent review of data read-outs.” In 2018, FDA issued the company a complete response letter that asked for more data before approval conditions could be met.
Novartis’ decision to walk away from its generic Advair development likely demonstrates the difficulty companies are having in showing bioequivalence for proposed orally inhaled drug products. FDA rejected similar applications from Mylan 3/2017 and Hikma 5/2017. In 1/2019, Mylan won final approval for its generic Advair copy, Wixela Inhub.
Novartis said its operating results include an impairment of $442 million because of the write-down of “in-process research and development” related to the discontinuation of the generic Advair development program.
