Thank you, Chris. Hello, everybody, and welcome to today's call. We had a strong start to the year, reporting first quarter total revenue of about $11.4 billion, an increase of 60%. Total revenues when excluding Vaxzevria for the quarter grew at 50%. Core EPS was $1.89, an increase of 20% over the prior year's quarter, benefiting from phasing and operational expenses, which our CFO, Aradhana will cover in more detail in a moment. Importantly, we delivered broad-based performance across our diverse disease area. Oncology grew 25%. CVRM increased 18%, R&I increased 4% and rare disease increased 7% on a pro forma basis. Our new consolidated vaccine and immune therapies area, V&I, delivered total revenue of $1.8 billion. This is the first quarter we have reported sales from this new disease area, which includes our COVID-19 vaccine, Vaxzevria and our long-acting antibody, Evusheld as well as Synagis and FluMist and soon, hopefully, nirsevimab. Iskra Reic, Executive Vice President of V&I, who is responsible for leading all V&I disease area activities is joining us for Q&A. We again saw robust news flow in the quarter, including EU approval in lupus for Saphnelo, U.S. approval in gMG for Ultomiris and U.S. Priority Reviews for both on Enhertu in HER2-mutant lung cancer and the combination of Imfinzi and tremelimumab in advanced liver cancer. Last but not least, we are particularly excited with the news from just 2 days ago with the fifth FDA breakthrough designation for Enhertu. This time in HER2-low breast cancer and based upon the data from our DESTINY-Breast04, which we look forward to sharing at the ASCO very soon. We have today reconfirmed our 2022 guidance with total revenue growth expected to increase at the high teens' percentage and core EPS growth to increase at mid to high 20s percentage. Please turn to Slide 6. Performance in the quarter was driven by growth across our diversified disease areas and geographies. Our business mix continues to evolve. And in a quarter, oncology comprised 32% of our total revenues. Biopharma, which includes CVRM, R&I and V&I, makes us approximately half of our revenues. Importantly, with the addition of Alexion, rare disease now makes up approximately 15% of revenues. The U.S., Europe, Emerging Markets and the Established Rest of World total revenues all saw strong growth in the period. And as you can see, the majority of revenues came from the U.S. in the quarter, followed by Emerging Markets. Our diversification in both these areas and geography reinforces our durable growth profile even in the face of industry-wide pressures, including pricing and reimbursement dynamics in developed markets and ongoing effects of the COVID-19 pandemic. Please move to Slide 7. With '22 off to a strong start, we are confident in both the near and long-term outlook for AstraZeneca. Looking ahead, we still have a number of key pivotal readouts that will not only reinforce our industry-leading science but also provide new growth opportunities. Notably coming up, we anticipate the Farxiga DELIVER trial readout in HFpEF and Ultomiris in the CHAMPION trial for NMOSD in the first half of this year. Looking beyond 2025, we are well positioned to continue to deliver industry-leading growth due to our robust lifecycle management, our innovative late-stage pipeline, but also complemented with our strategic business development efforts and importantly, a very durable exclusivity profile across the portfolio of commercialized products. We have multiple earlier stage opportunities to unlock significant potential post 2025 with the best-in-class top 2 antibody drug conjugate with Dato-DXd and our next-generation PARP1 selective programs in oncology as well as eplontersen, our novel TTR silencer in bioharma, and exciting new C5 and Factor D approaches in rare disease. With that, I'll now hand over to Aradhana Sarin, our CFO, who will walk you through our financial performance. Please advance to Slide 8.
