Item 8.01 Other Events.

On January 19, 2016, GlaxoSmithKline (“GSK”) informed Five Prime Therapeutics, Inc. (“FivePrime”) that the U.S. Attorney’s Office had arrested and charged certain individuals, including two former GSK employees, with theft of trade secrets from GSK, which theft included information related to FP-1039, FivePrime’s FGF ligand trap product candidate, which is partnered with GSK. On January 20, 2016, the U.S. Attorney’s Office issued a press release announcing indictments of these individuals. GSK informed FivePrime that the former GSK employees that were arrested and charged no longer have any access to GSK’s systems and their employment with GSK has terminated. FivePrime is investigating this matter to obtain additional information regarding this matter and its impact on FP-1039 and FivePrime.
