Puma Biotechnology, Inc. is a development-stage pharmaceutical company that is primarily focused on acquiring and developing drug products. At all relevant times, Puma’s primary focus has been the development of the drug PB272 (“neratinib”). Neratinib was initially developed by the pharmaceutical companies Wyeth and Pfizer Inc. (“Pfizer”), and Puma acquired the rights to license the drug in 2011.

Complaint alleges that throughout the Class Period, Defendants made materially false and misleading statements regarding the Company’s business, operational and compliance policies. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that:  (i) the Company did not anticipate that the U.S. Food and Drug Administration’s (“FDA”) would ultimately approve neratinib for the treatment of breast cancer; (ii) as such, Puma had overstated the drug’s approval prospects and/or commercial viability; and (iii) as a result, Puma’s public statements were materially false and misleading at all relevant times.

On May 4, 2017, post-market, Puma disclosed the resignation of Dr. Robert Charnas, the Company’s Senior Vice President, Regulatory Affairs, citing “health reasons.”  Dr. Charnas’ resignation will be effective as of May 15, 2017, nine days before the FDA scheduled review of Puma’s breast cancer drug neratinib on May 24.  On this news, Puma’s share price fell $5.85, or 16.01%, to close at $30.70 on May 5, 2017.
