Thank you, Sandy. Good afternoon, everyone. We remain confident in our ability to execute a successful launch for EXONDYS 51, as evidenced by the strength of the second quarter earnings and our updated net revenue guidance for the first full-year of launch. Our assumptions of the market size have not changed since launch. The team has done a good job ensuring physicians understand the importance of identifying and starting their patients on EXONDYS 51. This has resulted in increased market penetration, a continued flow of start forms and new patients adds every week. We expect this trend to continue as prescribers around the country identify additional patients through genetic testing and search their medical records in the clinic. Patient demographics have remained fairly consistent throughout the launch. The mix of patients on commercial and Medicaid plans remained approximately 60-40. We do not expect drastic changes in the mix of patients going forward. The average age of patients currently on therapy has held steady between 14 and 15 years of age, which indicates both ambulatory and non-ambulatory patients are obtaining access to EXONDYS 51. However, we have seen a large percentage increase in start forms from the first quarter of the year for the zero to four and five to nine age groups, respectively, followed by the 10 to 14 age group, which could predict the average age of patients on therapy trending down over time. From a compliance and persistence perspective, we have previously reported that approximately 40% to 50% of patients opted to have ports placed prior to their first infusion. Based on discussion with physicians, we expect this trend to continue. Although port placements initially slowdown the time to first infusion, we believe this leads to a better experience for the patient and better long-term compliance. Although we are still relatively early in the launch, we are seeing high compliance rates and minimal discontinuations at this point in time. From a managed care standpoint, reauthorizations are a standard part of the reimbursement process and we have not observed that major impact on persistence rates to-date. We believe our operational preparedness has supported this successful launch. Since approval, we’ve had over 4,500 healthcare provider interactions and over 280 institutional in services for outpatient clinics. While 100% of Tier 1 centers and 96% of Tier 2 centers have submitted start forms, we continue to see an increase in the number of new prescribers from our Tier 3 sites. At the end of the second quarter, more than 150 physicians have submitted the start form for EXONDYS 51. We believe that the increase in market penetration will contribute to the overall success of the U.S. launch. From a national account perspective, we had discussions with plans that represent greater than 260 million commercial and Medicaid covered lives. 77% of these accounts have requested additional medical discussions, and we continue to make progress with payers across the country. We believe payers have a much better understanding of the disease. The number of patients eligible for treatment under their plan and the patients who would most likely benefit from EXONDYS 51. We have previously highlighted that educating physicians, healthcare providers and DMD families about the importance of genetic testing would be critical for a successful launch. As discussed briefly before, we are continuing to see an increased rate of genetic testing and an urgency in many accounts to identify and test any patient who does not have one. As a result of this genetic testing, a greater number of physicians now know which patients have mutations that are amenable to skipping Exon 51. The deco Duchenne partnership with PPMD and Emory continues to see an increase in genetic testing, with more than 650 total applications submitted from approximately 250 providers since the beginning of the program. Our combined websites of sarepta.com, duchenne.com and exondys51.com have generated over 38,000 visits since launch. Duchenne.com, our unbranded disease education website for patients has generated over 18,000 visits in which greater than 1,300 Exon dilution tool searches were performed since December 2016. We have also had hundreds of genetic mutation worksheets downloaded as well. All of these efforts have led to newly diagnosed patients nationwide. We feel our educational efforts will continue to lead the way and increase genetic testing diagnosis and treatment, which will support the launch for the remainder of the year. We also believe these efforts will support enrollment in our – in all of our ongoing and future clinical trials. One of our goals is to maximize the number of patients who can access EXONDYS 51 globally. And as Doug mentioned earlier, the settlement of our patent litigation with BioMarin has given us freedom to operate for our Exon skipping compounds. Our managed access program launched today initially in select countries within Europe, North America and South America for certain patients, where EXONDYS 51 is not currently approved. We plan to expand the program to include more countries over the next few months. We continue to build out our European footprint. As previously reported, we have hired our GM of Europe and now have started interviewing country managers for select country clusters throughout Europe. And we’ve also secured our country manager in Canada. We’re in the process of selecting our Latin America GM and distribution partners, and have already selected partners in Israel, Saudi Arabia, Kuwait, Dubai and other countries in the Middle East. We will begin to launch access programs in these territories over the next few months. To recap, the commercial team has been focused and successful at continuing to obtain Exon 51 eligible start forms, supporting broad access for patients, retaining patients on therapy, increasing genetic testing and diagnosis through education, and building a global infrastructure to bring EXONDYS 51 to additional countries leveraging the U.S. FDA approval. To conclude, this is an exciting time for us at Sarepta. We have made progress on multiple fronts, have additional visibility into the launch of EXONDYS 51 and most importantly look forward to serving DMD patients around the world. And with that, I’ll turn the call back over to Ed for closing remarks.
