Thank you, Dr. Frost, and good afternoon, everyone. Let me start first with a discussion of our recently announced exclusive worldwide license and collaboration agreement with Merck, as mentioned by Dr. Frost. Securing a partner has been our strategy to advance the development of MDX-2201, our Epstein-Barr virus, multivalent nanoparticle vaccine. And EBV infects up to 95% of the global adult population during their life time and is associated with about 1% of all cancer cases worldwide. It also is the leading cause of infectious mononucleosis and recently has been implicated in the development of multiple sclerosis. Despite the prevalence of this virus and its role in causing life-threatening diseases, there are currently no FDA-approved vaccines or treatments for EBV. Our vaccine leverages ModeX innovative biologics platform to target 4 major EBV proteins. This multi-targeted approach improves upon previous efforts and holds potential to provide a complete protection against this infection. Under the terms of the agreement, OPKO received an upfront payment of $50 million and is eligible to receive up to an additional $872.5 million upon the achievement of prespecified development and commercial milestones. In addition, upon the commercial launch of MDX-2201, we're eligible to receive up to double-digit royalties on global sales. ModeX and Merck will jointly advance MDX-2201 up to the filing of an investigational new drug application, after which Merck will be responsible for all clinical and regulatory activities as well as product commercialization. Expenses incurred by OPKO for this program prior to full uptaking the responsibility by Merck will be reimbursed to OPKO as well prior to the IND. We are excited about this collaboration as MDX-2201 not only addresses an important unmet medical need. But as Dr. Frost said, it validates our approach of multi-targeting both in vaccines and with multi-specific antibodies, which is what ModeX does. Along with Merck, we're relying on advancing this vaccine with the goal of benefiting patients globally. In other parts of the pharmaceutical business, ModeX continues to make progress with other proprietary platforms. During the quarter, including MSTAR and STEALTH, these technologies have advanced. We've been following these multi-specific technologies to provide flexibility to go beyond 3 targets and up to a total of 6. We believe MSTAR is a plug-and-play platform that provides a competitive advantage over all the other multi-specific technologies with 28 patents filed to date. As we progress our therapeutic candidates, we will evaluate which targets we keep in-house and which we seek to partner in order to maximize the value of our pipeline. For example, we have a partnership with the NIH to provide funding for our Phase I trispecific candidate to both prevent and treat HIV. In addition, we're working on next-generation candidates targeting HIV, including and 1 petrospecific candidates with increasing potency. We believe there is a significant medical need as there are no vaccines or antibodies that can provide long-acting protection to prevent and treat infection and current HIV therapies despite their great progress still have limitations, including drug toxicity due to lifelong treatment and drug resistance that can impact efficacy of viral suppression. In addition to these efforts, we have worked on a COVID multi-specific antibody program to address the ongoing post-pandemic need to address the continuous appearance of variance of concern around the world even today. It is unclear what the evolution of the pandemic will be but we do believe that the pandemic will -- the virus will remain in the human population and will require a set of therapies to, in particular, help patients at risk because of existing conditions or suppressed immune systems. So we have a particular interest in exploring antibody candidates that can treat those patients at risk and can prevent maybe the development of COVID in these vulnerable populations. The advantage of our technology platform is that it is modular, which allows for rational selection of antibodies to optimize potency against current and future strains and prevent the emergence of viral resistance. Our SARS-CoV-2 multi-specific antibodies are currently in late preclinical testing and the development is partially funded by DARPA. In oncology, we have also multi-specific multifunctional antibodies, focused primarily on hard-to-treat solid tumors, but also for the treatment of leukemia and lymphoma. We believe the value proposition of multi-specific T cell engager antibodies has potential to demonstrate clinical efficacy for solid tumors and B-cell malignancies that the current standard of care does not sustain the remission in a large number of patients. Oncology programs are in the preclinical stage with a goal of entering the clinic in 2024. Let me refer you to our new website for more information and updates on publications and portfolio evolution, reachable at both as opko.com or modex.com. Let me turn now to RAYALDEE. We continue to achieve certain milestones with our international partners. In Germany, RAYALDEE was granted pricing approval, which triggered a milestone payment of $7 million from our . We're eligible to receive up to an additional $10 million in regulatory milestones and up to $207 million in milestone payments tied to launch pricing and sales of RAYALDEE plus tier double-digit royalties. In addition, we received a $2.5 million milestone payment related to Nicoya's submission of RAYALDEE's IND application to the Center for Drug Evaluation of China. We're eligible to receive up to an additional $150 million in payments upon the achievement of certain development, regulatory and sales-based milestones as well as a tiered double low-digit royalty on net sales by Nicoya in China. Now our program in Alzheimer's disease based primarily on the use of molecules that can mobilize plaques is currently exploring potential strategic partnerships with larger companies given the renewed interest that is now clearly present, including with the news today of the Eli Lilly results that affecting the protein deposits in plaques is actually potentially very effective. And our approach could be complementary to those of the antibodies used today or to be used in the near future in the patient population. So these programs are of high interest now because they do provide synergy potentially with existing and emerging therapies for Alzheimer's disease. Now I'd like to turn to our Diagnostics segment and discuss BioReference Health, which is the new name for what was previously called BioReference Laboratories. Our focus post-COVID remains on reducing costs and returning this division to profitability. We're expanding our reach initiative into 2023, which, to date, has been effective to improve efficiencies, enhance productivity and reduce costs. For example, we're starting to realize the economic benefits of shifting out of 13 less productive patient centers to 11 new more productive ones, which are more strategically located. In addition, we have increased our sales force primarily on the specialty diagnostics and health systems vertical and are also entering the pharmaceutical market in which we have not been present in the past. Our higher-value specialty testing segments continues to grow as we enhance our portfolio through innovation. These segments include oncology, women's health, urology and special ventures. For example, our GenPath women's health division was one of the first commercial laboratories to offer CINtec PLUS cytology. This is the only approved dual stain, triage test for patients who have a high-risk HPV results, high risk for the development of cancer. The dual stain biomarker test allows health care providers to more accurately and quickly assess the risk for cervical precancer and guide their management. As I mentioned, a key growth driver for BioReference is to offer new tests like this one from Roche to enhance its innovative portfolio and to provide valuable information for health care providers and their patients. In urology, our expanded commercial team is focusing on marketing and selling our proprietary 4Kscore test which is a blood test to evaluate a patient's likelihood of aggressive prostate cancer and help direct management of these patients. The urology team is also driving new accounts. And more importantly, the recent American Urology Association guidelines have validated the fact that consideration for the use of a 4K score or like tests is actually warranted in terms of the clinical guidelines they now provide to the urologists. And so we're going to expand our access for this test to other clinical services, hospital services and others as we are expanding our reach to those clinical services, hospital services as well as urgent care centers where we want to offer a complete menu of services. As we implement our strategy, we're getting closer to our goal of returning BioReference to profitable growth in a post pandemic environment, hopefully, over the next 3 quarters, which is what we're working towards. I will now turn the call over to our CFO, Adam Logal, to discuss our first quarter financial results. Adam?
