Thanks, Steve. It's an exciting time in Invivyd. Recently, we announced that we've nominated our proprietary combination, anti SARS-COV2 receptor binding domain or RBM studies for clinical development, which we are calling NVD 200. We look forward to describing the properties of these antibodies further, as we advanced towards clinical development. But of now one number of that combination is indeed a reengineered version of Adintrevimab our former lead molecule. This reengineering is an important subtlety, as our ability to evolve in Adintrevimab to rescue its activity against Omicron and its sub lineages with relatively few amino acid changes, supports our founding hypothesis, that there are indeed sites on the SARS-COV2 RBD that one can target with a monoclonal or multiple monoclonal and exert broad neutralization before through emerging variants of concern, as well as backwards to prior SARS-COV2 variants, and even more divergent for beta viruses such as SARS-COV2. As David mentioned, our plan is to utilize our integrated discovery platform against the threat of ongoing SARS-COV2 viral evolution, with ongoing novel antibody discovery and engineering, as well as to develop a best in class suite of early stage candidate antibodies that anticipate potential emerging variants. Our vision, which we look forward to engaging with global health authorities on in the coming weeks or months, is that a steady stream of viable antibody therapies for patients in the face of anticipated viral variation. To that end, we are pleased to announce today that we have multiple candidates in late stage discovery on track for plans preclinical activities in the first half of 2023. Each of the two components within our lead MBD to on this combination, as well as our other candidates represent unique molecules that have been shown in vitro to target distinct, amino recessive binding site on SARS-COV2 therapy. In addition, all have shown in vitro varying and sometimes subtle, or perhaps important differences in neutralizing potency across sub lineages, inaccessible strains. Put simply, they appear to be different, and to interact with the RBD in different ways that embrace the swarm of SARS-COV2 variants we currently see, our view is that those differences may turn out to be important and unpredictable ways going forward. In both development candidates, along with what we hope will be additional broadly, academic studies represent our anticipated growing and unique toolkit for addressing will be to continue to evolve each of these antibodies, rather like a hidden treasure map, which was re-engineered into [indiscernible] is a potential backbone for continuous, rapid engineering and evolution demands. In conclusion, our strategy, which follows uniquely from our integrated discovery platform is not to rely on a single molecule targeting a single epitope that may experience escape. Our strategy instead, is to continuously discover and engineer antibodies with sufficient initialization breadth and potency, such that patients in need have access to continuous, high quality protection even in the face of rapid viral evolution. We believe our integrated discovery platform offers a unique competitive advantage in this effort and the potential to provide a distinct benefit to patients in need, caregivers, and global health authorities searching for durable solutions to the ongoing burden imposed by COVID-19.
