The investigation focuses on whether Puma and certain of its officers and/or directors violated federal securities laws. On November 14, 2016, news of an investigation of an open-label Phase 2 clinical trial (“CONTROL”) was revealed. The investigation concerned the incidence rate of severe diarrhea (grade 3) in early stage HER2+ breast cancer patients receiving Puma’s Neratinib drug (the “incidence rate”). Following this high incidence of approximately 40%, the CONTROL study investigated the incidence rate where the antidiarrheal prophylaxis Loperamide was dispensed. The investigation showed a high incidence rate stayed at about 27% and that the CONTROL study was then extended to include a group of patients who were administered Loperamide and the corticosteroid Budesonide. The incidence rate did drop, but was still at 12.9%. When this news was announced, shares of Puma fell in value.
