Further study details as provided by Eli Lilly and Company:

Primary Outcome Measures:
  • To determine if the efficacy of oral dose of olanzapine is greater than oral dose of risperidone in acute schizophrenia by comparing changes in agitation from baseline to 3 days post-first oral dose

Secondary Outcome Measures:
  • To assess the efficacy of olanzapine compared with risperidone, in reduction of scores from baseline to 3 days as measured by the BPRS-T, PANSS-P, ACES, CGI-I and CGI-S.
  • To assess the efficacy of olanzapine compared with risperidone, in reduction of scores from baseline to 6 weeks of acute treatment in the BPRS-T
  • To assess the efficacy of olanzapine compared with risperidone, in reduction of scores from baseline to 6 weeks of acute treatment in the PANSS
  • To compare the change in severity of akathasia in schizophrenic patients between olanzapine and risperidone as measured by the BAS within the 6-week treatment period
  • To compare the change of severity of extrapyramidal symptoms within the 6 week treatment with olanzapine and risperidone, as measured by the SAS
