Thanks, Rob. I will divide my commentary on our first quarter results into three parts. First, I will describe the current operational status of Merck Research Laboratories, focusing in particular on clinical research and our interactions with regulatory agencies. Second, I will highlight some of the important results that we achieved during the first quarter and will outline some of what we hope to achieve as the year progresses. Finally, I will comment specifically on the actions that we hope and what we have taken to help address the COVID-19 pandemic. So let me begin with our operational status. As an early point, our global clinical operations team recognized the importance of the SARS-CoV-2 infections that were reported in Wuhan, China, and made advanced preparations to manage what became the COVID-19 pandemic. These preparations included prepositioning clinical supplies, strengthening our clinical supplies network, putting in place processes to enable virtual monitoring and over time developing processes for home deliveries, investigational agents, including in some cases, developing alternative infusion sites. Operating virtually the clinical operations team, including data management and our quality organization has been able to maintain our overall clinical trial schedule. We have in some cases reduced enrollment in certain jurisdictions. But we have not halted enrollment and are continuing to launch new clinical trials across most jurisdictions. As examples, our team processed 36 database logs in the month of March, and enrolled more than 700 new patients across our Europe, Middle East, Africa sites. These numbers provide substantial reassurance that our clinical programs are moving forward. Indeed, although I cannot predict what the course of the pandemic will be in the future, for now, our 2020 MRL objectives are not in jeopardy. This progress is owed entirely to the extraordinary work of teams across our organizations spanning five continents, and a very broad set of government regulatory agencies with whom we interact. Turning now to important research accomplishments. As noted previously, the first quarter began with FDA approval of KEYTRUDA as monotherapy for the treatment of certain patients with high risk, non-muscle invasive bladder cancer, our 23rd KEYTRUDA indication and we continue to generate important data related to the ability of KEYTRUDA to improve cancer therapy. An interim analysis of the pivotal Phase 3 KEYNOTE-355 studies demonstrated that KEYTRUDA in combination with standard chemotherapy improved progression-free survival versus chemotherapy alone in the first-line treatment of patients with metastatic triple-negative breast cancer, whose tumors expressed PD-L1 with a combined proportion score of greater than or equal to 10. This result complements the data from our KEYNOTE-522 study in which a combination of KEYTRUDA plus chemotherapy provided as neoadjuvant treatment versus chemotherapy alone improves the pathologic complete response rate in patients undergoing surgery for triple-negative breast cancer. We expect to describe these results in detail at an upcoming medical meeting. We also announced the results of our KEYNOTE-204 study which demonstrated that KEYTRUDA monotherapy improved progression-free survival in adult patients with relapsed or refractory classical Hodgkin lymphoma, as compared with brentuximab vedotin. These data strongly support our current indication in classical Hodgkin lymphoma. And the study will continue to permit evaluation of the dual primary overall survival endpoint. Also during the quarter, we announced the results of our KEYNOTE-177 trial, a Phase 3 study in which monotherapy with KEYTRUDA improved progression-free survival, as compared to standard chemotherapy in the first-line treatment of patients with unresectable or metastatic colorectal cancer, whose tumors had demonstrated deficiency in mismatch DNA repair or evidence of DNA microsatellite instability, the so called MSI high phenotype. The study will continue as is customary to permit evaluation of an overall survival endpoint once the data are mature. Most will recall that in 2017 we gained the very first approval of a tumor agnostic PD-1 directed therapy indication with the identification completed in collaboration with colleagues at Johns Hopkins University of MSI high status as a biomarker for tumor responsiveness. At the end of the first quarter, we also received priority review from the FDA for what we regard as a second potential tumor agnostic indication, the use of KEYTRUDA in certain patients whose tumors have a high mutational burden that is greater than equal to 10 mutations per megabase of DNA, irrespective of tumor type. We look forward to presenting all of these data at upcoming scientific meetings and in peer reviewed journals. As I've indicated, we are also engaged in discussions with regulatory agencies regarding these data. Finally, we announced last week that based on discussions with the FDA, we have responded to their prior Complete Response Letter and have resubmitted our application for approval of the use of KEYTRUDA in a 400 milligram every six weeks dosage form across all indications in adults, based both upon modeling information and new data that have emerged from our KEYNOTE-555 study, which will be discussed in part at the American Association for Cancer Research Meeting later today. We've also seen important progress in our partnership with AstraZeneca of Lynparza our leading PARP inhibitor. Just last week, we announced new results from a key secondary endpoint of our PROfound trial, which shows statistically significant improvement in overall survival in men with metastatic castration-resistant prostate cancer, whose tumors have mutations in the BRCA1, BRCA2 genes or the ATM gene, all of which are important for homologous recombination related DNA repair, following treatment of Lynparza as compared with abiraterone or enzalutamide therapy. The result provides yet another example of the benefit of Lynparza therapy in patients whose tumors have defined DNA repair mutations. I’ll remind you that we presented primary data from the PROfound studies at the European Society for Medical Oncology Meeting in October of 2019. We expect the details of the PROfound study, though not those just announced, will be published in the top tier medical journal in the very near future, perhaps this week. I should also note with respect to Lynparza that our PAOLA-1 study, a Phase 3 trial examining the combination of Lynparza plus bevacizumab versus bevacizumab alone in the first-line maintenance treatment of women with advanced overall -- ovarian cancer is under review by the FDA for the PDUFA date in the second quarter. I cannot complete our survey of important results in tumor therapy without mentioning the approval two weeks ago of Koselugo known generically as selumetinib which is the first selected therapy approved for patients with neurofibromatosis type 1 who are suffering from symptomatic, inoperable plexiform neurofibromis. The approval of Koselugo is part of our longstanding collaboration with colleagues at AstraZeneca, who first identified this important next signal transduction inhibitor. Beyond oncology, we also advanced important programs in other therapeutic areas. Earlier in the quarter, we had the opportunity to present the results of our Phase 3 VICTORIA study performed in collaboration with colleagues at Bayer which demonstrated that vericiguat, an investigational soluble guanylate cyclase agonist provided benefit as judged by composite endpoints including heart failure hospitalization or cardiovascular death as compared with placebo, when given as add on therapy to well treated patients with established heart failure with reduced ejection fraction who had suffered a worsening event. This represents the first study of its kind in the population at very high risk for further cardiac complications. The data were published in the New England Journal of Medicine and presented virtually at The American College of Cardiology Meeting just last month. Also during the quarter we announced that in our Phase 3 program, gefapixant, our investigational P2X3 antagonist reduced the 24 hour cough frequency in patients with longstanding chronic cough. Details of these results will also be published and presented in the not too distant future. Finally, in the metabolic disease area, we have just announced results for the Phase 3 VERTIS CV cardiovascular outcomes trial. In this study conducted jointly by Merck and Pfizer, compared administration of STEGLATRO an oral sodium-glucose cotransporter 2 or SGLT2 inhibitor versus placebo in the treatment of patients with type 2 diabetes and established atherosclerotic vascular disease, and achieved its primary endpoint of non-inferiority for major adverse cardiovascular events. These events were defined as time to the first event of CV death non-fatal myocardial infarction or non-fatal stroke. The key secondary endpoints of superiority for STEGLATRO versus placebo for time to the composite of CV death or hospitalization for heart failure, CV death alone and the composite of renal death, dialysis/transplant or doubling of serum creatinine from baseline were not met. While not a pre-specified hypothesis for statistical testing, a reduction in hospitalization for heart failure was observed with STEGLATRO. The safety profile of STEGLATRO was consistent with that reported in previous studies. Detailed results of VERTIS CV are scheduled to be presented on June 16th at the virtual American Diabetes Association’s 80th Scientific Session. I will now describe activities during the past quarter directed at developing treatments that could have an impact on the course of the COVID-19 pandemic. As a leading vaccine manufacturer for more than 100 years, it is no surprise that we have embarked upon a broad-based development program for SARS-CoV-2 vaccine. Let me put these results in the proper context. Vaccine development is extraordinarily difficult and customarily requires many years of investigation. As others have noted during the past quarter century, despite enormous efforts, there have been only seven vaccines directed against previously unaddressed human pathogens that earned registration. Four of these seven were developed by Merck Research Laboratories. And so we have relevant experience in this area. ERVEBO, our most recent vaccine, which has been demonstrated to provide protection from -- with the Zaire strain of Ebola virus, was developed rapidly and under emergency use authorization to help address outbreaks in West Africa. Nevertheless, there required a multiyear development program and involved building a factory that we're proud to say can produce 1 million doses of vaccine per year. The development and registration of ERVEBO required the efforts of hundreds of our employees as well as an extraordinary commitment from the World Health Organization and then from healthcare workers in Guinea, Sierra Leone, the Democratic Republic of the Congo and many other jurisdictions. With the COVID-19 pandemic, however, we are tasked with creating a completely new vaccine in 1/10th the time that we devoted to ERVEBO, and we must plan to manufacturer this vaccine at 1,000 times the scale. We approached this challenge with enthusiasm but also with humility. We know from long experience that creating safe and effective vaccines typically requires decades of efforts and investment. We're mindful of the imperative to act with speed indeed with urgency. Based on the progress that we have made, I will say that I am optimistic that a vaccine capable of inducing a potent neutralizing immune response to SARS-CoV-2 can be invented. But it's also critical to develop a comprehensive understanding of this particular coronavirus which will allow us to design, develop and ultimately to manufacture vaccine that can be deployed globally. With this in mind, we have first supported efforts to characterize effective immune responses to SARS-CoV-2 infection. As we announced yesterday, we have partnered with scientists at the Institute for Systems Biology, Swedish hospital, and the Providence health system, all in Seattle, with Stanford University and numerous others to collect cells in sera over multiple time points from patients diagnosed with COVID-19. Data derived from these analyses will be made available to researchers worldwide, and will position us to cipher correlates of immunity to this coronavirus. With respect to the vaccines themselves, we have been thoughtful in selecting proven platforms that we’ve used to generate vaccines with desirable qualities in the past. Of course, in light of my prior comments regarding the difficulty of developing successful vaccines, I cannot guarantee to you that any of these approaches will prove effective in the near-term. However, you should have no doubt that scientists in our own laboratories and those of our collaborators are committed to this process. We've also worked to identify internal resources that can support the manufacture of these potential new vaccines at an appropriate scale. And we are in discussions with contract manufacturers who could assist in what would surely rank as the most challenging vaccine production initiative ever undertaken. Beyond our search for vaccines, we are also engaged in studying potential antiviral drugs that could be deployed more rapidly. Here too we have evaluated compounds in our own laboratories, and have identified programs at other laboratories that could prove beneficial. Time does not permit me to describe these programs in detail. Instead, I would like to mention that the global community of biopharmaceutical companies has been very open to collaboration to address this challenge. Within MRL, we are trying to help as many of our colleagues as we possibly can, both through the active consortium led by the National Institutes of Health and also through interactions with many companies large and small, that have contacted us for advice and assistance with their own programs. I will close by emphasizing that at Merck our mission is to translate breakthrough research into medicines and vaccines that improve and extend life. This mission has never seemed more vital than it does today. I wish to express my gratitude to all of my colleagues here at Merck for working tirelessly in pursuit of a means to ameliorate the COVID-19 pandemic. I'll now return the call back to Peter.
