Thank you, Carlo, and good morning, everyone. Last week, we announced our agreement to sell Seres VOWST assets of commercial rights to Nestle Health Science in exchange for substantial immediate and future financial consideration. We held a call at that time to review the agreement and the deal terms and to provide a high-level view of our planned corporate strategy to advance our live biotherapeutics drug candidates, which are consortia bacterial strains cultivated from clonal master cell banks and rationally design and optimize target disease-relevant pathways. Today's call will focus on our SER-155 program, and the clinical data we look forward to obtaining next month and more broadly, our strategy moving forward. Later in the call, we will provide a review of our second quarter financial results. I'll begin with a recap of the VOWST asset sale and how this helps to support advancement of our pipeline. We expect the transaction to close in the next 90 days. As we discussed last week, the VOWST asset sale provides Seres with a meaningful capital infusion. Upon deal close, pending stockholder approval, we will receive $155 million in cash, which includes an upfront payment, a prepaid milestone payment and an equity investment, net of operational obligations we pay Nestle at close. The capital provided will strengthen our balance sheet, enable us to retire our existing debt facility and certain other operational liabilities and, most importantly, support the development of our pipeline of wholly owned live biotherapeutics that build upon our previous successes and represent the next generation of our drug technology. We are proud to have developed VOWST as the first ever FDA-approved oral live microbiome therapy. VOWST has transformed the lives of thousands of patients with recurrent infections. Preventing devastating recurrences of infections for individuals who have limited FDA-approved therapeutic options. In developing VOWST, we created numerous capabilities including entirely new manufacturing methods, and we collaborated with the FDA to secure regulatory approval for a product in an entirely new class of oral biotherapeutics. Looking ahead, we believe that the capabilities, know-how and core intellectual property that we have developed over the last decade and our underlying technology platforms position Seres to continue to successfully advance new biotherapeutics and to address significant unmet medical needs and additional medically vulnerable patient populations. We believe that there are near-term opportunities to apply our drug technology to prevent serious bacterial infections and related conditions such as bloodstream infections and febrile neutropenia in high-risk patients, such as allo-HSCT patients. In the longer term, we plan to leverage our acquired capabilities and other diseases and conditions. More specifically, we believe we can develop our biotherapeutics to prevent infection in multiple medically vulnerable patient groups and we could address also GI immune-related diseases such as inflammatory bowel disease. In summary, we believe the VOWST asset sale will enable Seres to create meaningful new biotherapeutics for diseases that are not able to be effectively addressed with conventional approaches thereby creating value for patients and other stakeholders. The transaction enables us to transform Seres into a number and more streamlined organization, deploying our financial and human capital to advance in pipeline assets through discovery and clinical development, core competencies of Seres. We will be well positioned to build upon our extensive technical capabilities and to advance the development of potentially transformative new treatments for many serious diseases. Our lead program, SER-155 is being evaluated in an ongoing Phase Ib study, and we are looking forward to obtaining important clinical data next month in the placebo-controlled cohort 2. We anticipate this readout will extend the positive results observed in Cohort 1 and further highlight the potential for our novel therapeutic approach, expanding our prior clinical successes. Seres is also developing another proprietary live biotherapeutic composition, SER-147 to improve clinical outcomes in patients with metabolic disease, including those with chronic liver disease and those at high risk of bacterial infections. Matt will discuss this program shortly. I'll now pass to Lisa to discuss SER-155 in more detail.
