Thanks, Reshma. Today, I will review our continued strong performance and outlook in CF as well as potential near-term commercial launches in new disease areas with exa-cel and VX-548. Starting with CF, where we continue to bring our transformative medicines to many more patients globally. Last month, we raised our estimate for the number of patients with cystic fibrosis in the U.S., Europe, Australia, and Canada to 88,000 up from our previous estimate of 83,000. The growth in the CF population can be attributed to more patients coming forward to receive treatment, better data capture in patient registries, and perhaps most importantly, people with CF are living longer due to improvements in patient care and the availability of truly effective therapies. For a baby born with CF in 2021, the Cystic Fibrosis Foundation predicts the median age of survival is now 65 years. In the U.S., our focus remains on maintaining the very high persistence and compliance rates we have seen with our therapies and extending the benefits into younger age groups. Outside the U.S., uptake of KAFTRIO/TRIKAFTA in countries with recent reimbursement agreements continues to drive growth, as has the rollout of KAFTRIO in children ages six to 11 years in countries where this indication has recently received reimbursed access such as France and Spain. There are still more than 20,000 CF patients who could benefit from, but are not on CFTR modulator treatment. These patients fall primarily into two categories. One, patients in countries where we are early on the launch curve, and two, younger patients for whom we continue to pursue additional label and reimbursement extensions, such as the recent U.S. approval of ORKAMBI for ages one to two years and recent regulatory submissions for KALYDECO in children ages one to four months, and for TRIKAFTA in ages two to five years, which has received Priority Review and a PDUFA date of April 28 in the U.S. We are confident that we will reach the vast majority of these patients over time, which will continue to drive revenue growth in the near and long-term. We also see exciting growth potential for our vanzacaftor triple combo given the anticipated clinical profile, more convenient once daily dosing, and the potential to offer a new option for patients who have discontinued prior CFTR modulator therapy. Finally, in CF, as Reshma mentioned, our CFTR mRNA program VX-522 is being developed for the more than 5,000 CF patients worldwide who currently do not have any therapies that treat the underlying cause of their disease. I will now detail our commercial readiness efforts and the market opportunity for two potential product launches outside of CF, exa-cel and VX-548. Exa-cel holds curative potential for patients with sickle cell disease and transfusion-dependent beta thalassemia, and we are making significant progress with launch preparation activities. Our initial launch of exa-cel will focus on the approximately 32,000 individuals in the U.S. and Europe for whom these diseases are most severe, presenting a significant clinical, humanistic and economic burden. The estimated 25,000 severe sickle cell disease patients have multiple hospitalizations annually for vaso-occlusive crisis, while the estimated 7,000 TDT patients undergo near monthly transfusions. There is also a considerable financial burden both for these patients and to the healthcare system. In the U.S. economic models project the lifetime treatment costs for severe sickle cell disease patients to be between $4 million and $6 million. Recent market research indicates that physicians have a strong preference and interest in gene editing over other potentially curative approaches. And that patients with sickle cell disease are increasingly optimistic about the potential role for curative therapies in the treatment of their disease. In addition, payors view the emerging clinical data for exa-cel as highly impactful, most notably the reductions in vaso-occlusive crisis and hospitalizations. Importantly for our specialty commercial model, these 32,000 severe patients are concentrated geographically and we believe can be served effectively with a network of approximately 50 authorized treatment centers or ATCs in the U.S. and approximately 25 in Europe. We have established the needed supply chain and manufacturing infrastructure to support the launch, including validated chain of identity and chain of custody systems, global shipping infrastructure, and the needed manufacturing capacity to support uptake following approval. And finally, we continue to work with key commercial and government payors and policy makers in the U.S. and Europe to ensure they understand the significant burden of these diseases and that broad patient access and reimbursement are in place if and when exa-cel is approved. To date, we have engaged with all U.S. state Medicaid agencies, some 150 unique U.S. commercial payors, as well as multiple health technology assessment bodies in Europe, including NICE and GBA, to share important information about exa-cel and our commitment to working collaboratively to provide access to this therapy. Shifting now to VX-548, which we believe has the potential to play an important role across the pain spectrum, including acute pain and chronic pain conditions. I’ll focus my comments on acute pain, which is a near-term commercial opportunity. There are four aspects critical to framing the acute pain opportunity for Vertex. One, there is a significant unmet need due to the limitations and drawbacks of currently available treatments. Two, the market is large today, even with 90% generic prescribing. Three, prescribing is concentrated in the hospital setting and thus addressable with a specialty commercial infrastructure. And four, there is broad stakeholder recognition of the need for new therapies, which also helps provide a clear path to future patient access and reimbursement. Firstly, millions in the U.S. suffer from acute pain each year, yet it is often difficult to manage effectively given the limitations of existing therapies. The current standards of care are NSAIDs and acetaminophen at one end of the spectrum, which are non-addicting, but offer limited pain relief and can pose GI and liver toxicity concerns. And at the other end of the spectrum are opioids, which provide effective pain relief, but have many undesirable side effects, including nausea and somnolence and have significant abuse potential. Many large hospital systems and all 50 states have adopted restrictions for the use of opioids. This leaves a vast gap in the treatment landscape for a medicine like VX-548 with strong efficacy, a desirable benefit risk profile, and without abuse potential given it is peripherally acting. Second, the acute pain market is very large valued in the U.S. at $4 billion, despite 90% of prescriptions being generic. Third, this highly concentrated market can be served with a specialty commercial model. Of the 1.5 billion treatment days for acute pain annually, some two-thirds or 1 billion are driven by hospital prescribing, following inpatient or outpatient procedures such as surgeries or emergency room visits. Furthermore, these hospital-driven prescriptions are concentrated among approximately 1,700 hospitals that aggregate to roughly 220 integrated delivery networks. Thus, we believe we can reach a large proportion of this market with a specialty sales and marketing infrastructure and have begun to hire for key positions. Fourth, and finally, given the wide stakeholder recognition of the limitations of current treatments and the unmet need, we see both high demand and a clear path to access and reimbursement for a medicine with a profile like VX-548. A key example of the path to reimbursement and access is the recently passed NOPAIN or Non-Opioids Prevent Addiction in the Nation Act signed into law last December. Through the NOPAIN Act, Congress has directed CMS to make a separate add-on payment to hospitals in the outpatient and ambulatory surgery center setting for non-opioids for the treatment of pain. We believe this new law is an important sign of the growing movement to remove barriers for hospitals, providers and patients to utilize non-opioid treatment options. In closing, we are excited about the opportunity to extend the benefits of our CF medicines to more patients around the globe and the near-term potential to commercialize transformative treatments for patients with sickle cell disease, beta thalassemia and acute pain. I will now turn the call to Charlie to review the financials.
