Lannett Submits ANDA For Generic ADVAIR DISKUS®

PHILADELPHIA, April 1, 2021 /PRNewswire/ -- Lannett Company, Inc. (NYSE: LCI) today announced the submission of an Abbreviated New Drug Application (ANDA) for Fluticasone propionate and Salmeterol inhalation powder (100/50 mcg, 250/50 mcg and 500/50 mcg) to the U.S. Food and Drug Administration (FDA), by its strategic alliance partner, Respirent Pharmaceuticals Co. Ltd. The product is the generic equivalent of ADVAIR DISKUS^® of GlaxoSmithKline. Total U.S. sales of the product, according to IQVIA market, were approximately $3 billion for the 12 months ending February 2021, although actual generic market values are expected to be lower.

"The ANDA submission of generic ADVAIR DISKUS^® marks a significant advancement toward our goal of adding larger and more durable products to our portfolio," said Tim Crew, chief executive officer of Lannett. "We anticipate a rigorous FDA review, extending beyond one review cycle, for the ANDA, given this is a complex combination drug/device product, involves two active pharmaceutical ingredients (APIs) and includes multiple dosage strengths.

"Currently, our agreements with Respirent include generic Advair Diskus, as well as second powder inhaler product, generic Flovent^® Diskus^® (Fluticasone Propionate Powder Inhaler). A key element of our growth strategy is to further build a franchise of respiratory drug/device products, and we are currently evaluating and in negotiation for additional product opportunities. We believe we have gained valuable experience during the development of the product and will learn important insights on the regulatory front, which we can bring to bear on these potential future opportunities."

Commenting on Respirent, Crew added, "We continue to build an effective, close working relationship with our colleagues at Respirent – a team that has expertise and a deep working knowledge in developing, filing and manufacturing inhalation products and is committed to bringing affordable respiratory products to market."

As previously announced, Lannett entered into an exclusive U.S. distribution agreement for the therapeutically equivalent generic of ADVAIR DISKUS^® (Fluticasone Propionate – Salmeterol Xinafoate Powder Inhaler) of Respirent. Under the agreement, Lannett will commence U.S. distribution of the product after FDA approval and receive a portion of the net profits once it commences distribution of the product. The companies recently extended the term of the agreement to 12 years, which begins upon commencement of distribution. Other terms were not disclosed.
