Lilly's pomaglumetad methionil fails to meet clinical endpoint

12 July 2012

US drug major Eli Lilly (NYSE: LLY) announced today negative clinical trial results from study H8Y-MC-HBBM (HBBM) investigating pomaglumetad methionil, also known as mGlu2/3, for the treatment of patients suffering an acute exacerbation of schizophrenia.

In study HBBM, pomaglumetad methionil did not separate from placebo in the primary efficacy endpoint in either the overall or predefined genetic subpopulation (based on the Positive and Negative Syndrome Scale, PANSS) at the two doses investigated (40mg and 80mg BID). The active control, risperidone, did separate from placebo in both populations. Pomaglumetad methionil was generally well tolerated in this study, with no new safety findings compared to previous trials. Data will be shared at a later date at an appropriate scientific venue.

HBBM was intended to be the first of two clinical trials to support registration of the compound for monotherapy in acute schizophrenia. The second registration clinical trial, H8Y-MC-HBBN (HBBN), is ongoing.
