Eli Lilly
In a surprise move, the Food and Drug Administration issued a non-approvable letter for the injection because of questions about the "excessive sedation events" seen in patients taking the drug. Rather than issue an approvable letter or a narrow label for the drug, the FDA ignored the advice of a somewhat positive advisory panel that had voted in favor of approval.
The rejection of Zyprexa LAI is unfortunate for Lilly. It would have had a very strong competitive advantage versus other atypical antipsychotic drugs because of its superior every-four-week dosing. This long-acting treatment matters because schizophrenics often don't follow recommended dosing, and with it, it's relatively easy to see if a patient is sticking with his or her therapy.
There are already several long-lasting versions of the less desirable typical antipsychotics on the market. Johnson & Johnson's
Other drugmakers, like Vanda Pharmaceuticals
Zyprexa LAI could have easily become a blockbuster therapy for Eli Lilly because of the huge need to improve many schizophrenics' compliance with therapy. The consolation prize for Lilly investors is that the FDA non-approvable letter won't affect sales of its Zyprexa tablets that are taken daily. But Zyprexa sales may come under pressure in the second half of the year as Johnson & Johnson's Risperdal starts to face generic competition.
