(The following press release from Roche Holding AG was received by e-mail. The sender verified the statement.) Roche provides update on the first two of six phase III studies of bitopertin in schizophrenia • Two phase III studies evaluating bitopertin for persistent, predominant negative symptoms of schizophrenia did not meet their primary endpoints; third study is ongoing • Three phase III studies evaluating bitopertin for sub-optimally controlled symptoms of schizophrenia are ongoing Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that two phase III studies of its investigational medicine bitopertin (RG1678) in adults with persistent, predominant negative symptoms of schizophrenia failed to meet their primary endpoints, based on the negative symptoms factor score of the positive and negative symptom scale (PANSS). Negative symptoms include social withdrawal and lack of motivation. In the studies, adding bitopertin to antipsychotic therapy did not significantly reduce negative symptoms at 24 weeks compared to placebo. Bitopertin was generally well tolerated and its overall safety profile was similar to that seen in the previously reported phase II trial (NN20372). A third phase III study evaluating bitopertin for persistent, predominant negative symptoms of schizophrenia is ongoing. In addition, three phase III studies investigating bitopertin for sub-optimally controlled symptoms of schizophrenia are in progress. Sub-optimally controlled symptoms, such as hallucinations and delusions, are symptoms that do not resolve despite treatment with an antipsychotic. “These results are disappointing for people with negative symptoms because more effective treatments are needed for these debilitating effects of schizophrenia,” said Sandra Horning, M.D., Chief Medical Officer and Head of Global Product Development at Roche. “We will await data from the remaining bitopertin studies in schizophrenia before deciding on next steps.” more With best regards, Roche Group Media Relations Roche Group Media Relations Grenzacherstrasse 124 4070 Basel, Switzerland Phone: +41 61 688 88 88 Fax: +41 61 688 27 75 mailto:email@example.com www.roche.com Confidentiality Note: This message is intended only for the use of the named recipient(s) and may contain confidential and/or privileged information.
