The Klein Law Firm announces the commencement of an investigation of Roche Holding AG (OTCMKTS: RHHBY) concerning possible violations of federal securities laws.

On June 5, 2017, news reports stated that a new study showed that adding Roche Holding’s breast cancer drug Perjeta to its older treatment Herceptin only had a slight benefit while more than doubling the one-year treatment cost; and that the combination of Perjeta with Herceptin had higher rates of certain side effects than Herceptin alone. When this information was released, shares of Roche Holding fell in value.
