Thanks, David. I'm delighted to be here after six years on the Board of Scholar Rock. As a physician scientist, I could not be more excited to have seen the concept of apitegromab, our highly innovative anti-myostatin antibody, go from bench to bedside with our remarkable SAPPHIRE data. SAPPHIRE showed that apitegromab has the potential to reverse the progression of SMA from a loss of motor function to a gain of motor function. Specifically, the study demonstrated a statistically significant improvement in Hammersmith whilst patients on placebo worsened. Importantly, patients treated with apitegromab had an approximately threefold higher chance of a three point or greater increase in Hammersmith versus those on placebo. Along with the very encouraging safety profile, the SAPPHIRE data suggests that apitegromab has great potential to provide clinically significant benefit to patients with SMA despite the use of background SMN target therapies. Additionally, at the Muscular Dystrophy Association Conference in Dallas in March, the detailed data from the SAPPHIRE trial were presented for the first time. These data demonstrated that treatment with apitegromab achieved clinically meaningful and consistent benefit in motor function across pre-specified SMA patient subgroups, including the type of SMN targeted therapy, age, age of initiation of SMN therapy and geography. Efficacy was also supported by additional analyses of outcome measures of motor functions, such as the Revised Upper Limb Module and the World Health Organization Motor Development Index. As David mentioned, our BLA was accepted under priority review by the FDA and the MA was validated by the EMA in Europe. Turning first to the FDA. We were gratified that our BLA for apitegromab was granted prior to review by the agency with a September 22nd PDUFA date. We feel the potential clinical benefits of apitegromab as demonstrated by a Phase 3 trial are underscored by the FDA's priority review designation. By definition, a priority review designation by the agency conveys the capacity of apitegromab to potentially impact unmet need in SMA by either being a treatment for a serious or life threatening condition or provide a significant improvement in safety or effectiveness over existing treatments. I'm excited that our team continues to work collaboratively with regulators and that we remain on track. With the success of SAPPHIRE, we're just beginning to tap into the broader potential of our truly innovative myostatin platform. There's much more we can do with the promise of apitegromab and our platform by delivering advances in severe neuromuscular diseases, including the muscular dystrophies, such as DMD and FSHD. Additionally, we're advancing SRK-439, a highly innovative and potent subcu anti-myostatin antibody to the clinic. Based on preclinical data, SRK-439 has the potential to inhibit myostatin and increase muscle mass and creates options for our pipeline. We remain on track to file the IND application for SRK-439 to support the first in human study in Q3. Now earlier, David mentioned the potential role Scholar Rock can play in addressing lean mass in cardiometabolic diseases. As we all appreciate, whilst GLP-1s offer quantitative benefits in terms of weight loss, much more needs to be done from a qualitative perspective regarding preserving lean mass. Notably, a quarter to a third of the weight loss with GLP-1s is due to the loss of muscle. Looking forward, it will be important to preserve muscle from the viewpoint of the associated metabolic benefits and a healthier approach to weight loss. Our EMBRA
