On February 2, 2017, TheStreet published an article entitled “Side Effect Kills Cancer Patient in Stemline Therapeutics Drug Trial, the Company Raises Money.”  TheStreet reported that investors who bought into a $45 million Stemline Therapeutics stock offering on January 19, 2017 were not told that one day prior to the financing, a cancer patient in a clinical trial died from a severe side effect, a type of low blood pressure, tied to the Company’s SL-401 drug.

This news drove the price of Stemline shares down over 42% on February 2, 2017.

“A cancer patient’s death occurring from Stemline SL-401 related side effects is a tragic event and is a fact reasonable investors would want to know about,” said Hagens Berman partner Reed Kathrein.
