That's great. Thank you, Jim. Good morning everyone. So this was a fantastic quarter for Alkermes and it caps off a remarkably productive 6-month period, with significant progress made across the company, including the close of the EDT merger, the launch of Bydureon in EU and the approval of Bydureon by the FDA, positive date on ALKS-9070 and the start of our clinical program and encouraging data on ALKS-4061 and the accelerated start of that phase II study in major depressive disorder.
Alkermes now has the elements in place to become a major biotechnology company. It's not by accident; it's the result of putting in place an amalgam of people, technologies, manufacturing capabilities, commercial products, financial resources, and scientific expertise. All of these elements enabled to 2 majors growth drivers for calendar 2012.
First, we have a powerful financial engine in place and we set clear financial targets that we're managing the business to meet. Second, we have an increasingly valuable late-stage pipeline, and a R&D strategy that's focused on return on investment. And I'll cover these in turn.
The financial engine is driven by these 5 key commercial products. Risperdal Consta, Invega Sustenna, and Ampyra, Vivitrol and Bydureon. Each of these products is a singular product in its class, on patent for a long time, and in a way, these products have hardwired growth potential into our P&L for the next several years.
So let's start with Bydureon. As I'm sure you know by now, we and our partners at Amylin announced last Friday that Bydureon was approved by the FDA, making it the first and only once weekly, GOP1 approved by it in the US. Congratulations to our colleagues at Amylin and to the many Alkermes employees who worked so hard on Bydureon for so many years. So now Bydureon joins our expanding list of commercial products available to patients in the U.S. and around the world.
In the US, Amylin will be responsible for the sales and marketing of Bydureon. We're encouraged by their commitment and focus on successful execution. Amylin will utilize the commercial force of 650 diabetes sales specialists, many of whom have previous market experience with both Byetta and Symlin. Outside the U.S., Amylin intends to seek a commercial partner, and we understand that those discussions are underway in earnest.
Bydureon is a game changer in the treatment of Type 2 diabetes, and we're very proud of our role in its development. We expect it to be a meaningful contributor to our growth and margin expansion since we have no costs associated with the product, just pure royalties on net sales. Amylin announced the price for Bydureon on their conference call last week of approximately $323 per month, which is a slight premium to Byetta, and a discount to high-dose Victoza. We think that's smart at this price point. For the only once weekly diabetes medication, it provides continuous glycemic control. This will be attractive to physician, patients, and importantly payers.
Turning to the atypical franchise. On a combined basis, Risperdal Consta, and Invega Sustenna sales are growing at a double-digit rate. Recall that Risperdal Consta is approved in more than 90 countries with the majority of its sales coming from outside the U.S. At the E.U. launch of Invega Sustenna or Xeplion is just now beginning. So we believe we are at the beginning of a protracted period of expansion for this franchise.
For Ampyra, at the beginning of January, our partners at Acorda announced strong, unaudited net sales for the fourth quarter, as the U.S. launch continues to gain momentum. Outside the U.S., Biogen has now launched a product in Germany, Australia, U.K., Norway, Denmark and Iceland. We expect an E.U. launch to roll out to additional countries as reimbursement discussions are finalized.
Acorda has also stated that they are advancing the development of potential new indications for Ampyra in M.S. and other CNS diseases. These potential new indications represent large markets with significant unmet medical need. And it is exciting to see the extent of the clinical research supporting the future potential of Ampyra.
On the Vivitrol front, this quarter marked our 10th consecutive quarter of growth, as we continue to roll out the opioid-dependence indication. Looking over the longer term, you have heard us talk about and we continue to be interested in the opportunities for Vivitrol in States and in the Criminal Justice system.
This is the part of the market that we think Vivitrol has the ability to essentially dominate as the only once-monthly, non-addictive opiate receptor antagonist that prevents relapse to opioid dependence.
These 5 commercial products, each with intrinsic growth, will drive our financial performance. They are complemented by the late-stage pipeline. Before I provide an update on some of the late-stage candidates themselves, let me discuss briefly our targeted ROI-driven R&D strategy.
The idea is to do very little basic discovery work. We design molecules rationally, in order to solve a particular clinical or medical opportunity, characterize them rigorously pre-clinically, and then move quickly into cost effective studies in humans that can give us a clear proof-of-concept.
This approach allows us to assess the viability of new pipeline candidates early and devote our resources to advancing the most promising candidates quickly to registration of staged trials. This approach has been incredibly productive, and has yielded what we believe is an exciting CNS pipeline that we expect will generate meaningful new drugs, ones that become important new treatment options in their classes and also sources of significant revenue for Alkermes into the next decade and beyond.
Consistent with this approach, ALKS-9070 is a proprietary, injectable, long-acting, new chemical entity that metabolizes in the body into Aripiprazole, which is available commercially as Abilify. We knew exactly the type of molecule we needed to design in order to meet pre-specified clinical and commercial criteria. A phase III study of ALKS-9070 is underway in enrolling patients. This multi-center trial is designed to include 690 patients with schizophrenia, and will be enrolling throughout this year. Data from this study are expected in mid-calendar of 2013. We are very excited about the prospects for ALKS-9070.
Separate from the inherent features of Aripiprazole as an anti-psychotic, namely the efficacy and tolerability. We see 2 key differentiating features of 9070. The range of doses we can deliver, and the product presentation itself. Based on our human Phase I PK data, we believe we can offer 9070 dose strengths to cover the full range of oral Abilify doses, including the highest dose that is commonly used to treat schizophrenia.
This is an important attribute, as it will allow a clinician to easily transition a patient from any daily dose of oral Abilify to a corresponding monthly dose of ALKS-9070. In addition, we have learned through our experience with Consta and Sustenna that product presentation matters in the real world. We are designing ALKS-9070 to be a ready-to-use pre-filled syringe. This is a huge opportunity for us, one that leverages much of our experience, and we are very excited to be advancing this program.
ALKS-37 is a drug you will be hearing a lot more about in the coming year. ALKS-37 is our orally active, peripherally restricted opiate antagonist, for the treatment of opioid-induced constipation. 280 million prescriptions were written for opioid analgesics in the U.S. in 2010, which is an incredible number when you think that there are only about 300 million people in the entire country.
Most patients on opioid therapy will experience GI motility problems. We designed ALKS-37 to have precise opioid receptor selectivity, and to be orally available and metabolically robust, so they can be dosed once a day. Further, in addition to designing it not to cross the blood-brain barrier, we designed it to stay in the GI tract with low systemic exposure, with the goal of not only making it effective but very well tolerated.
We saw evidence of these features in the Phase II data we presented last year. And we expect to see these qualities reinforced in the clinical data in our ongoing Phase II-2b program, which includes more than 200 patients and is expected to read out in mid-calendar 2012. We then plan to move forward with 2 parallel Phase III study.
Another proprietary CNS candidate, ALKS-5461, is a sophisticated opioid-receptor modulator. Just a few weeks ago, we announced the positive results of a Phase I-b study of 32 patients, with major depressive disorder who failed standard therapy. 2 things about the data caught our attention.
First, the magnitude of the anti-depressant effect, and second, the rapid response the patients had to treatment with 5461. At day 7 of the study, ALKS-5461 was shown to significantly reduce depressive symptoms, as measured by the Hamilton Depression rating scale.
As you may know, SSRIs and other medications can take weeks to illicit a pharmacological response, so to see such a clear signal, in a small number of patients and achieve statistical seen evidence by day 7, you can see why we have moved very quickly to expand and elaborate these findings in a bigger Phase II study which is now underway.
We expect that data in-hand in the first half of calendar 2013. This is a large market with an estimated 6 million patients in the U.S. who don't adequately respond to their first course of treatment, who need a well-tolerated, non-addictive treatment with a new mechanism of action.
I'll end where I began. This was an excellent quarter, and the beginning of something very important. These 2 elements, a powerful financial engine coupled to an increasingly valuable and late-stage pipeline, create a really exciting company with all the elements in place to build what we think is going to be one of the next big biotechnology companies.
With that, I'll finish and turn the call back to Rebecca for questions.
