Decision Resources, Inc., one of the world's leading research and advisory firms focusing on pharmaceutical and healthcare issues, finds that Eli Lilly's Zyprexa will remain the gold standard for the treatment of schizophrenia through 2015. According to a new report entitled Schizophrenia: Turning Physician Insight into Projected Patient Share, Zyprexa is superior in efficacy to all other current therapies, particularly on measures that are most important to prescribers, such as impact on global symptoms and responder rate.

In spite of scoring* less favorable than the other drugs in terms of safety and lower than risperidone in terms of delivery features, Zyprexa is the gold standard. This overall advantage for a drug with significant safety concerns highlights the importance of efficacy to prescribers.

The report also finds that the most commercially important emerging antipsychotics (Janssen's Invega, Organon BioSciences' asenapine, and Wyeth/Solvay/Lundbeck's bifeprunox) score* lower than Zyprexa, indicating that Zyprexa will remain unsurpassed during Decision Resources' forecast period.

"Invega is a metabolite of risperidone and is likely to have efficacy similar to that of risperidone, which scored* slightly lower than Zyprexa overall," said Nitasha Manchanda, Ph.D., analyst at Decision Resources. "Asenapine also lacks the differentiation to replace Zyprexa as the gold standard because it does not make as significant an impact on global symptoms, and bifeprunox is significantly inferior to Zyprexa in all primary efficacy measures and is not capable of surpassing Zyprexa."
