Rajiv Malik
President at Viatris
Thank you, Michael and good morning everyone. We had another strong quarter and are very pleased with the positive momentum across our entire business driven by strong commercial performance supported by excellent customer service levels, continued scientific execution of our diversified pipeline including a historic first approval of an interchangeable biosimilar to insulin glargine.
This was achieved while we continue to successfully integrate, restructure, and navigate the COVID-19 pandemic. Our performance would not be possible without the dedication of our global workforce and I would like to thank them for their continued commitment.
Over the next several slides, I will walk you through the performance in each of our segments and product categories. I will be making certain comparisons to the combined LOE adjusted second quarter 2020 results on a constant currency basis as well as comparisons versus our expectations as included in our initial guidance.
Beginning on Slide 6, each of our segments and product categories delivered a strong performance. When excluding the impact of Japan's Lyrica and Celebrex LOEs as seen on the bottom left-hand side of the slide, net sales were up 4% this quarter as compared to the combined LOE adjusted quarter two 2020 results. Our brand business grew by 3% year-over-year and performed better than our expectations.
We are pleased to report that our global biosimilar grew by 40% this quarter while our overall complex generics and biosimilars category declined by 8% year-over-year mainly due to anticipated competition on certain products in our complex generics portfolio. Our global generics business grew by 8% year-over-year and performed better than our expectations.
We delivered $224 million for new launches in the second quarter and as we look ahead, we remain on track to meet our $690 million target in 2021. We believe that the diversity of our portfolio and commercial reach positions us well to balance the impact of any changes in the market and eliminates our reliance on any one product or geography. Accordingly, we expect our base business to continue to perform strongly.
Turning to Slide 7, our developed markets segment grew by 2% year-over-year. This was primarily driven by brands like Yupelri, Dymista, and Creon. Our Thrombosis portfolio also performed better than expected, which continues to highlight our ability to effectively manage and grow established brands and expand our presence in the hospital segment. Our biosimilars performed strongly with 47% growth this quarter, which helped offset the negative impact of the previously anticipated competition to Wixela and Xulane.
Our generics portfolio also performed better than our expectations primarily driven by our U.S. injectables portfolio as well as favorable COVID-related buying patterns in Europe. Having said that, we see our biosimilars portfolio driving continued growth while offsetting anticipated competition in our complex generics space.
Moving to the next slide, our emerging markets segment delivered 12% year-over-year growth and performed better than our expectations. Brands like Viagra and Lyrica drove strong performance as certain countries started recovering from COVID. Our better than expected results of our generics business was helped by certain COVID-related products.
The next slide shows that our JANZ segment grew 6% year-over-year and performed in line with our expectations. Our brand portfolio of products like Lyrica and EpiPen primarily contributed to the strong performance of Japan. We continue to be pleased with the growth of our generics business in JANZ especially the contribution from our expanded authorized genetics offering including authorized generics to Lyrica and Celebrex. It should be noted that approximately half of the overall generics growth is due to the termination of our collaboration with Pfizer from the prior year.
The next slide is our last segment slide and shows that our Greater China business once again delivered a strong performance, which was better than our expectations. Our retail channel showed double-digit growth and our hospital channel performed better than our expectations while managing the impact of VBP and URP. The 3% year-over-year decline was driven by anticipated VBP implementation of Celebrex and Zoloft. As we look at the rest of the year, we anticipate the full year to be better than our original expectations although we see that second half being softer than the first because of the implementation of URP.
Now turning to Slide 12, which highlights our proven track record of introducing several first to market complex products. Breaking down barriers goes beyond best-in-class science and right from day one, our cross-functional team of R&D, regulatory, legal, medical, and policy experts work diligently and collaboratively with regulators, partners, and other stakeholders to seek and create pathways to clear hurdles that enables access. It can take on an average seven to nine years from development to regulatory approval given the highly complex nature of these molecules.
Getting to the finish line requires tremendous perseverance, tenacity, and an unwavering commitment to patients. The success stories of receiving the first approval for our COPAXONE 40 milligram, ADVAIR, NEULASTA, HERCEPTIN, SYMBICORT and most recently, the first interchangeable biosimilar through the LANTUS give us great confidence that we are well positioned to deliver on our pipeline. We intend to leverage our deep scientific capabilities to further expand access to the complex products for patients.
I will now walk you through some key pipeline updates, starting on Slide 30. As it relates to our biosimilars key pipeline, I would like to take a moment to echo Michael's remarks and applaud the efforts of so many Viatris colleagues who played a huge role in achieving this historic FDA approval of the first interchangeable biosimilar, Semglee. We look forward to launch this exciting opportunity before the end of the year.
Moving to Aspart, a pre-approval inspection from FDA of Biocon's manufacturing facility in Malaysia is now scheduled for the end of this quarter. Scientifically, we believe we are on track to achieve interchangeability for Aspart which should further expand our portfolio of interchangeable insulins. We remain on schedule for a submission in quarter four of this year for Eylea. Our program for BOTOX is progressing well and we have a meeting scheduled with the FDA in September of this year to align on our path forward.
Moving to biosimilar to Avastin, while we have no open scientific questions with FDA, our U.S. approval has been impacted by the delay in a pre-approval inspection due to COVID travel restrictions. The same product has been approved by TGA, MHRA and several other regulators. As you will see on the next slide, we continue to make steady progress on our complex products program and have some important upcoming milestones. We submitted our 505(b)(2) application to FDA for our Levothyroxine Oral Solution in June as planned.
For our Meloxicam, we expect an IND submission with Phase 2b study planned for quarter four this year. We are excited with the progress of our new low dose formulation of Xulane and we plan to initiate our clinical dosing for our Phase 3 program in September. We also continue to make comprehensive progress on our complex injectable pipeline. We are happy to report that we are first to file on paliperidone once three months product equivalent to INVEGA TRINZA on the 546 milligram and 829 milligram strengths. The remaining strength of 410 milligram and 273 milligram have already been submitted and are pending acceptance from FDA.
Before I conclude, I would like to touch upon our integration and restructuring activities. Since closing the transaction almost nine months ago, our teams have been hard at work to ensure no business disruptions. We remain on track to realize $500 million of cost synergies this year and confident in our overall plans to achieve at least $1 billion of cost synergies by 2023. Let me now turn the call over to Sanjeev. Thank you.
