Josh Smiley: Thank you, Samantha. It is an exciting time at Zai Lab as we launched VYVGART, the first FcRn blocker approved for the treatment of generalized myasthenia gravis in China. There are over 170,000 patients in China living with gMG, many of whom continue to suffer from symptoms, such as decreased muscle strength and mobility despite receiving treatment. VYVGART is an important new treatment option for gMG and has the potential to significantly change the way patients are treated today. We've already made significant progress through our outreach efforts, having engaged around 75% of our top 200 hospitals since launch in September. And while we are still in very early stages of the launch of VYVGART, we are encouraged by the positive feedback from neurologists and patients.
