Thanks, Brian. Good afternoon, everyone. Our second quarter 2012 performance was highlighted by acceleration on our core OmniPod business, which grew by nearly 30% year-over-year. The investments we made in sales and marketing over the past six months have begun to provide a return more quickly than we originally anticipated.
Since January 1st, we have added approximately 20 members to our commercial team, including a new inside sales capability which launched on May 1st. These new investments coupled with the completion of the infrastructure -- integration of the Neighborhood Diabetes acquisition have resulted in a high powered commercial team driving increased patients demand.
In the second quarter, referrals swelled by more than 20% year-over-year, the highest rate of increase in a quarterly period since 2009. While internally we are all eagerly anticipating the approval of the next generation OmniPod, our external message about the benefits of the current OmniPod continues to resonate to patients and healthcare professionals that there is no reason to wait.
Patients are starting the therapy on the current OmniPod System and immediately enjoying the features such as no tubing, a discreet watertight design and automatic cannula insertion. Customers clearly continue to appreciate that the OmniPod System gives them the freedom to do what they want, when they want, without the hassles of conventional style pumping.
With demand accelerating in the OmniPod business, our operations team has kept pace by increasing production volumes, improving quality and driving cost efficiencies. We manufactured more than 1.4 million OmniPods in the second quarter, a record level of production. This has allowed us to build our inventory levels, which will help facilitate the transition from the current OmniPod production line to the next generation OmniPod line.
Importantly, we have not sacrificed quality as we have increased production quantity. We're very proud to say that the quality of the OmniPod has never been better. The number of calls received has dropped for nine consecutive months with an overall decline by nearly half since last October. These production and process refinement efforts have also resulted in a financial benefit, as the cost per pod dropped below $14, helping to improve our overall gross margins by approximately 130 basis points.
The operation teams also continues to make excellent progress in preparing for the launch of the next generation OmniPod. Our manufacturing capacity continues to increase for lines one and two, and we've commenced work on our third line. We remain on track to have the capacity produce between 750,000 and 1 million new pods per month by the end of the year.
You'll recall on our last conference call we discussed that supply chain readiness was an area of focus for us. I am pleased to report that while there is some work left to do, we have made significant progress across the entire supply and network to ensure that we are ready to go upon the approval with the next generation OmniPod.
Let me now update you on the regulatory approval process for the next generation pod. While not yet approved, we have continued to make positive strides with the Food and Drug Administration towards that goal. Over the past couple of months, we have been in regular contact with the agency and noted in June that the remaining list of questions have been winnowed down to approximately five; we responded to those questions 10 days later.
A few weeks ago, the agency provided us with two final comments that they believe need to be resolved before the review of our 510(k) submission could be successfully completed. One relates to a labeling change and the second concerns some of the human factors data that we have provided with our most recent response.
As part of their comment, the agency requested additional human factor testing to be completed. In particular, the agency noted that there were areas of potential user error in our original human factor testing where the patient incorrectly entered data such as a Basal rate, blood glucose value or the setting of the PDM clock. Although these areas were infrequent, the agency requested that we revisit certain aspects of the PDM user interface, our user manual and our training procedures to identify ways for us to help further reduce the likelihood of these use errors.
Our internal team along with our human factors consultants and the FDA have since held a series of meetings where we identified minor product modifications which should reduce the potential occurrence of these errors. We believe the changes are relatively minimal such as including confirmation screens, PDM user interface to allow the user to validate the data they have entered is correct.
We submitted these proposed updates to the product as well as to protocol where the additional human factor testing to the FDA and are currently awaiting their feedback. We expect to submit an updated response to the FDA approximately four to six weeks from the proceed of their feedback.
But we can't convert our patient base to the next generation product until we receive 510(k) clearance from the Food and Drug Administration. We are using this additional time to ensure that every group within the organization is ready for our patient conversion. We are looking at this as an opportunity to further derisk the transition and ensure a successful launch across our commercial manufacturing and support teams. We remain confident that once approved, we will be able to execute the transition in an expeditious manner.
We also remain confident regardless of the time of the actual approval that we will be at or near operating cash breakeven by the end of the year. We are committed to making sure that the first impressions in new OmniPod are extremely positive. If the feedback from the American Diabetes Association meeting is any indicator, it certainly will be. At the ADA conference in Philadelphia this past June, we unveiled the OmniPod in our booth and to a series of informational events geared towards key opinion leaders.
We continue to showcase the next generation OmniPod this past week at the American Association of Diabetes Educators Conference in Indianapolis. The reaction to the size and weight difference as well as the user intubation enhancement geared towards improving the overall customer experience has been excellent. We're confident that the new OmniPod, once approved, coupled with our newly strengthen commercial team will position us for continued rapid top line growth in 2013 and beyond.
Our international partnerships continued to be a significant contributor to our future growth expectations. Ypsomed continues to add patients and takes share of the insulin pump markets across this territory including the Netherlands, Germany and the UK. Just recently they're launching OmniPod into the Austria market and have plans for additional markets to come on line in the coming quarters.
We have been working closely with Ypsomed on the rollout of a next generation OmniPod across Europe. With the summer holiday season nearing its end, we anticipate that they will begin to accelerate the transition to next generation OmniPod in the fall with all patients converted by the end of the year.
In Canada, GSK also continues to make good progress driving OmniPod adoption across the country. With the pending approval of the OmniPod here in the U.S., we recently filed the next generation OmniPod for approval with Health Canada and anticipate an approval there some time in the first half 2013.
Turning to Neighborhood Diabetes, June marked the one-year anniversary of our acquisition of this business. I'm more convinced than ever that the opportunity that exists with Neighborhood Diabetes high touch service model. The infrastructure has been integrated and as mentioned earlier, we're now experiencing benefits of the combined team in helping to drive OmniPod growth.
Over the past several quarters I've talked about what differentiates Neighborhood Diabetes is their high-touch service model, where we play key role in training encouraging and supporting patient therapy adherence. This model has been proven case studies to reducing number of hospitalizations for patients serviced by Neighborhood Diabetes versus those who are not.
In a managed care environment that is becoming more and more outcome driven, our message is resonating with payers. They are more willing to work with us as a provider of choice, several plans have provided us access to their customer list as the diabetes management preferred supplier.
Recent strategic account wins are opening new geographies for Neighborhood Diabetes in places such as the Southeastern U.S. and in Texas. We are working closely with these payers to obtain customer list and just start placing calls to those patients offering our services in the coming months.
While we are convinced that this strategy of focusing on these managed care relationships positions Neighborhood Diabetes well for higher levels of long-term growth, delays in receiving customer list from these plans did impact second quarter revenues. We are continuing to work closely with the clients to iron out the executional complexities and expect to seeing return to higher levels of growth and Neighborhood Diabetes in the back half of the year.
In addition the pipeline remains strong, with several other strategic accounts hopefully coming on board in the second half of 2012. While all of us at Insulet are focused on the next generation OmniPod and the smooth transition upon approval, we are also moving forward with several other initiatives.
Last quarter we announced the signing of the global agreement with LifeScan, Inc., a subsidiary of J&J. As part of this agreement, we're integrating LifeScan's One-Touch's blood glucose monitoring technology into our handheld personal diabetes manager.
The combined LifeScan-Insulet team has made tremendous progress on this combined device, and we believe that we remain on track to make this produce available in the market in 2013.
Recently we have had several conversations with DexCom and expect to soon commence the work required to develop an integrated handheld using their fourth generation sensor and our next generation OmniPod.
In addition, we now expect that this integrated device will leverage our new partnership with LifeScan as well as integrating the [indiscernible] blood glucose meter and [indiscernible] device. Although our primary mission is focused on making the lives of people with diabetes easier, we also continue to explore several non-insulin drug delivering opportunities, which leverage the OmniPod.
Our goal in these types of engagements just to leverage our existing technology with the limited customization for the delivery of this specific drug. To date we've seen favorable results on this projects. We are hopeful that we will see couple of these relationships move towards commercial opportunities over the coming quarters.
With that I'll turn the call over to Brian to provide additional details about the second quarter results and our expectations for the remainder of 2012.
