Rajiv Malik
President and Executive Director at Viatris
Thank you, Michael, and good morning. I'm excited by our strong results this quarter that reflect on focus business execution on all fronts. We manage the base business, maximize new launches, delivered on our pipeline and continue to execute our integration and TSA exits all while advancing our reshaping initiatives.
Let me start with an update on transactions with Biocon Biologics. We are progressing with all regulatory approvals and importantly have clearance from the U.S. antitrust perspective. The remaining regulatory approvals are expected in the coming months. Biocon is also on track with securing its financial commitments. With this positive momentum, we are well-positioned to close this transaction in the second half of '22.
Now moving to our quarterly segment results which begin on Slide 7 of our earnings slides posted on our website. As I walk you through the performance in each of our segments and product categories, I will be making certain comparisons on an operational basis versus our plan that supported our guidance, we communicated back in late February. Our developed market segment continues to be a strong and resilient commercial business built on a foundation of a very diversified portfolio of brand generics and complex products, which has allowed us to improve the predictability and sustainability in what continues to be a dynamic and challenging environment. In North America, we continue to demonstrate our focus and dedication to patients through [Technical Issues] based on the strength of our proven development capabilities. Our interchangeable biosimilar Semglee is off to a great start as the total prescription share approaches 10% which is in line with our expectations. Generic Restasis is another example of a first-to-market complex product and is also off to a strong stock.
Moving to our generic Symbicort named Breyna, we are very excited to receive FDA's final approval in March. This milestone furthers our track record of successful for us [Phonetic] in developing complex generic medicines to help increase patient access. It is a trial scheduled for May 19th in the West Virginia federal court, and we continue to have the opportunity to launch this product in 2022 as upcoming proceedings develop. Other key products like Yupelri and Wixela performed in line with our expectations, while showing year-over-year double-digit volume growth. Our European business is also off to a solid start and remains on track to grow mid single-digit for the full-year '22. Italy, France, Spain, and Portugal performed strongly to further enhance our retail channel leadership in these countries. We also saw stronger than expected performance across brands such as Creon, Lipitor, Dymista, Lyrica, and ibuprofen.
Our thrombosis portfolio continues to grow in line with our expectations. Hulio our biosimilar to Humira, which adds roughly 20% plus market share of the biosimilar market is another key contributor to our German and France businesses. Our recently launched generic Revlimid is the first in CDs of key launches planned for Europe this year.
Our emerging market segment showed a strong quarterly performance. Our ARV franchise performed slightly better versus our expectations this quarter. Key geographies such as South Korea, Southeast Asia, and Turkey drove higher volumes, while Brazil realize better pricing. Lipitor and Lyrica led to strong growth in this segment and helped the brand category perform better than expectations.
Moving to Jan [Phonetic], the headwinds on account of annual government NHI price reductions in Japan, are being partially offset by strong year-over-year volume growth of our authorized generics and brands like celecoxib, Amitiza, and Effexor. In addition, we saw strength in Creon and EpiPen in Australia versus last year. On biosimilars, we are pleased that Hulio has achieved more than 50% market share in Japan however, we continue to believe that there is plenty of room for the overall Humira biosimilars market to grow as it only stands at 10% today.
Lastly, an update on Greater China. Our strong and brought Marshall infrastructure has helped us to deliver a strong performance despite COVID and COVID-related lockdowns our retail channel performance especially Viagra was slightly impacted by COVID which was more than offset by better than expected performance of the hospital channel primarily led by Lipitor. Our manufacturing operations in China continue to perform well and at this time, we do not foresee any potential disruption to our China supply chain. Given our solid start to the year and a strong customer service performance across all segments delivered by our global supply chain, we remain confident to deliver on our full year expectations across all segments on an operational basis.
Switching now to our pipeline. For your benefit we have included current snapshots in our earnings materials, beginning on Slide 13. There are a few noteworthy pipeline updates. Our Eylea biosimilar review is progressing well and we can confirm that we have no outstanding science issues. We are currently waiting for the facility approval by FDA. As a reminder, this program is a part of Biocon transaction. Our biosimilar to BOTOX filing for USA, FDA will be delayed. We remain committed to the successful development of this complex biosimilar with Revance and to the earliest possible launch in the United States. Our clinical trial for GA once-monthly has a number of patients who are located in Ukraine and are being impacted by ongoing situation there. As a result, we are pushing back or FDA filing by one quarter it is now scheduled for the first quarter of '23. We recently received FDA approval of our Levothyroxine Oral Solution named [Indecipherable] and are looking forward to launching later this year. Also, we received a GDUFA goal date of October '22 for our potentially first to file generic Pentasa. Lastly, we believe that we achieved first to file status Abilify Maintena further enriching our first to market opportunities of complex injectables which now include Paliperidone 3-month, Octreotide LAR, ferric carboxymaltose, iron sucrose and semaglutide.
And finally, an update on integration as you can see on Slide 17, we remain on track to realize $500 million of COGS synergies over the next two years resulting in at least $1 billion cumulative COGS synergies since becoming Viatris. Our objective throughout this year is to complete our TSA exits from Pfizer, making Viatris self-allign [Phonetic] in terms of systems and processes and positioning the company to further accelerate the optimization of our infrastructure. Before I conclude, I would like to thank our colleagues for their hard work to deliver yet another excellent quarter and lay a solid foundation for the year. With that, let me now turn the call over to Sanjeev.
