Invega Betters Seroquel, but to What Advantage?

Where do I even start? I guess I should start by pointing to one of the articles on this new trial data release. So, big shocker...in a trial of 400 patients with acute exacerbations of their schizophrenia symptoms who were willing to submit to hospitalization for at least 10 days, Invega showed better efficacy scores on the PANSS than did Seroquel *yawn*. Anyone care to guess what percentage of the US population meets those criteria? An even better question is what percentage of Seroquel's patient population is at risk? It's got to be at least 2 maybe 3 patients. Why even bother with this study? OK, and I'm reaching here, perhaps Janssen is considering a re-launch with a focus on more severe patients representing a new willingness to cannibalize its own Risperdal share and perhaps steal some share from the perennial metabolic whipping boy Zyprexa. At least now JNJ will have something to tout on their conference call.

One point I failed to mention in my last post on Invega is mentioned in the article. With regards to the slow uptake it notes "Invega sales got off to a slow start earlier this year partly because managed-care plans didn't give the drug as favorable a position on their preferred-drug lists as J&J, New Brunswick, N.J., would have liked." There's little doubt that this is true. JNJ was trying to suggest Invega was at price parity with Risperdal when in fact a one-day supply was about twice the cost. MCO's saw through it and either didn't add them to formularies or placed them on a different tier than JNJ had forecasted. Someone with more knowledge than me around managed care formularies should comment here to further elaborate.
