Amphastar Stock Down on CRL for Asthma Drug in the U.S.

Amphastar Pharmaceuticals, Inc. AMPH announced that its subsidiary, Armstrong Pharmaceuticals, Inc., has received a Complete Response Letter (CRL) from the FDA for a New Drug Application for its over-the-counter (OTC) bronchodilator product, Primatene Mist (epinephrine inhalation aerosol). The company’s shares lost 9.1% following the news.

Amphastar’s one-month share price movement shows that the stock has underperformed the Zacks classified Medical – Generic Drugs industry. Specifically, the company gained 0.5%, while the industry improved 1.5%.



The CRL has requisitioned changes in the candidate’s label as well as packaging. The FDA also necessitated another Human Factor validation study to measure consumers' ability to use the product without consultation with a doctor or a pharmacist.

In 2013, the company filed an NDA for Primatene Mist and received a Prescription Drug User Fee Act date in May 2014. However, in May 2014, the company received a CRL from the FDA, asking for additional non-clinical information, label revisions and follow-up studies to assess consumers’ ability to use the device correctly to support its approval in the OTC setting. The company met with the FDA in Oct 2014 to discuss preliminary data results and to clarify the requirements for further studies. The company received advice regarding its ongoing studies from the FDA in Jan 2016, and completed the human factor studies accordingly. Thereafter, Amphastar submitted the amended NDA on Jun 28, 2016 and received a target response date of Dec 28, 2016.

The company now plans to work with the FDA during the post-action phase to address the regulatory agency’s concerns by mid 2017.

Note that Primatene Mist offers a new inhalation delivery system, which no longer consists of chlorofluorocarbons (CFCs). This comes as part of an international environmental treaty aimed at phasing out CFCs from various products.
