Thank you, Susan, and good afternoon, everyone. It's been an exciting and productive time since I joined the company earlier this year. And I'm pleased to say sales are off to a solid start and on track for all 3 of our trusted opioids-sparing products, which continue to make an important impact on patients' lives. This year, our priority is EXPAREL, which is we're all focused on today. I'll also touch briefly on PCRX-201.
Let's start with EXPAREL. Our goals are centered on preparing the organization and marketplace to fully realize its long-term potential. Let me walk you through the progress we've made in advancing 3 key drivers for 2024: First, advancing the launch of EXPAREL in 2 new lower extremity nerve block indications; second, progressing our awareness and educational activities around separate Medicare reimbursement and average selling price, or ASP, plus 6% in outpatient settings beginning in 2025 with the implementation of NOPAIN; and third, expanding patient access to EXPAREL through 340B pricing and new GPO partnerships such as Premier.
I'll start with lower extremity nerve block, where we're seeing positive market receptivity across all sites of care, delivering 4 days of opioid-sparing pain control with a single 10 ml EXPAREL dose is an attractive value proposition to the anesthesia and surgical community for knee, foot and ankle surgeries. Physicians are also reporting consistent results with some patients not taking any opioids following very painful lower extremity procedures. To remind you, we launched with a strong presence in the TKA segment.
We're also working to build relationships and advanced product uptake through education and training in other lower extremity procedures like ACL repair, foot and ankle procedures. We would expect a slower uptake in this segment of the market.
Turning now to the opportunity ahead with the upcoming changes in EXPAREL reimbursement for outpatient procedures. Separate CMS reimbursement of EXPAREL across all outpatient settings marks an important milestone. It will eliminate the cost barrier by fully reimbursing EXPAREL at ASP plus 6% beginning in January of 2025. Given the market steady migration away from hospital inpatient care, we see ample room for expanding EXPAREL utilization in outpatient settings. We've allocated resources to drive education and help health care systems implement EXPAREL as best practice standard of care for CMS patients.
There are roughly 6 million annual CMS procedures in the outpatient settings with a split of roughly 3.5 million procedures in the hospital outpatient settings and 2.5 million procedures performed at ambulatory surgical centers.
To maximize this important opportunity, we're enhancing our organization with new talent and capabilities to ensure operational excellence within critical functions such as marketing, strategic accounts, medical and market access. In parallel, we're advancing initiatives to drive awareness, education, action across key decision makers.
We're also paving the way for NOPAIN through our participation in 340B pricing and new GPO partnerships. Earlier this year, we announced a partnership with Premier whose significant network of hospitals and health care systems covers nearly 20% of EXPAREL relevant market procedures. Through these preferential pricing programs, we're helping health care systems afford the opportunity to be at the forefront of opioid-sparing pain management.
While still early days, we're pleased with the initial data we're seeing from our partnership with Premier. In the first 2 months of post-launch, EXPAREL volumes at Premier accounts are up with only a modest impact on net sales dollars. In short, this partnership is starting to do what we expect it to do. Importantly, we have 2 additional GPO partnerships in process.
As for ZILRETTA and iovera°, I'm pleased to say both products are performing according to plan with solid sales growth for the quarter. With respect to margins, while EXPAREL landed in our guided range, ZILRETTA and iovera° margins weighed on consolidated margins for the quarter. Charlie will share more details on margins shortly, but I want to emphasize that our primary focus is on driving top line growth. As we grow the top line, margins will in turn benefit.
Switching gears to our research and development pipeline. I'd like to share a few quick updates on PCRX-201. This novel intra-articular helper-dependent adenovirus gene therapy product candidate that codes for interleukin-1 receptor antagonist, or IL-1Ra for the treatment of osteoarthritis, OA, of the knee. Here, we believe PCRX-201 has the potential to become a leading disease-modifying agent by turning the patient's own cells into therapeutic production sites of IL-1Ra.
As background, IL-1 is a known inflammatory cytokine with inflammation tied to the reduction in catabolic processes in the joint that contribute to OA of the knee and progression. Last month, we presented encouraging preliminary results from a 72-patient Phase I study of PCRX-201 at the Osteoarthritis Research Society International, or OARSI, 2024, World Congress in Vienna. The data will also be featured as a noncore podium presentation at the Annual Meeting of the American Society of Cell and Gene Therapy this week in Baltimore.
This data showed that a single intra-articular injection of PCRX-201 demonstrated sustained clinical effect as assessed by patient-reported outcomes at all dose levels for at least 1 year post-injection. Importantly, PCRX-201 was shown to be well tolerated with a favorable safety profile. We now have data through 2 years, and we are preparing to submit those data for presentation at a medical meeting in the fall.
Of the 14 million Americans suffering from symptomatic OA of the knee, 2 million are under the age of 45. The duration of effect for currently available treatments is limited to 3 to 6 months. Based on our market research and feedback from our Scientific Advisory Board, improving pain and function while potentially modifying the disease for a year or more would be considered transformative by both physicians and patients.
Furthermore, a year or more of durability would be clinically and economically meaningful for patients and the health care system. These promising preliminary findings earned PCRX-201 the FDA's first ever Regenerative Medicine Advance Therapy, or RMAT, Designation for gene therapy product in osteoarthritis. Lastly, unlike other gene therapies, we believe PCRX-201 will be able to be manufactured at large scale for a favorable cost of goods sold.
Before I turn the call over to Charlie for a review of the financials, I'd like to highlight today's announcement of our plans to implement a $150 million stock repurchase plan. This stock repurchase plan underscores our confidence that we have in our growth outlook, and the belief that Pacira shares offer an attractive investment opportunity given the significant value ahead.
With that, I'll turn the call over to Charlie for his financial report.
