Thanks, Hannah. Good afternoon, and thank you everyone who has joined us today for our third quarter 2022 earnings call. I am proud to announce what many have been waiting to hear. We recently filed our IND application for mural liver ELAP with the FDA. We are pioneering a new class of medicine and believe that this is the first IND to be submitted to the FDA for a bioengineered organ, putting us one step closer to realizing our goal of saving and improving patients' lives and eliminating the organ transplant waiting list. We will wait for the FDA's feedback and plan to initiate a phase one clinical trial shortly after receiving their clearance. I'm incredibly proud of our entire team for achieving this important milestone. Before I provide additional updates on our three programs in development, I'd like to quickly remind everyone about our technology platform and a few key points of differentiation. So very quickly, MuralMatrix bioengineers organ for human transplant utilizing our proprietary two-step decelerization and resellerization technology platform, which is applicable to all organs. Our initial focus is on bioengineering livers and kidneys, which account for nearly 95% of the organ transplant waiting list. We own all of the core IP around perfusion decelerization and recelerization technology, which has an important point of differentiation versus alternative technologies, such as gene editing, which fall under the umbrella of xenotransplantation. Xenotransplantation is characterized by the presence of living animal cells in the product. These living animal cells have been the source of some key challenges facing xenotransplantation, notably pig virus transmission and organ rejection. We believe that our bioengineered organs will not be regulated as xenotransplantation because a decelerization step is designed to remove the living animal cells from the organ. We have also demonstrated the required viral inactivation steps to reduce the risk of any pig virus transmission. The second step, resellerization, repopulates the decelerized matrix with human cells, and therefore, we believe our bioengineered organs will possess a rejection profile similar to human-to-human organ transplants. Finally, it is easy to visualize the operational efficiencies, such as supply chain and cost of goods, that our technology enables. Hopefully, that gives everyone a good refresher of our technology and a few key points of differentiation. Now I'll provide status update on our three programs in development, Mural Liver ELAP, Mural Liver, and Mural Kidney. As I mentioned at the beginning of the call, we recently achieved a major milestone and filed our IND application for Mural Liver ELAP. We plan to initiate a phase one clinical trial shortly after receiving IND clearance from the FDA. I would like to extend personal gratitude to John Berry, Mason McKensky, Peggy Norris, Joel Britton, and Chris Fecteau and the members of their teams for achieving this important milestone. I know how hard they've all worked to accomplish this goal. Thank you all and congratulations. Mural liver ELAP is our external liver assist product that we developed to treat patients suffering from acute liver failure or ALF. The liver is the only organ in the body that can regenerate itself and mural liver ELAP is designed to help in that process. Think of mural liver ELAP as liver dialysis, where a patient's blood is circulated through one of our bioengineered livers that can reside bedside in a chamber connected to a continuous renal replacement therapy system, or CRRT. Over the course of treatment, the patient's blood is continuously filtered and returned to the patient. through the closed-loop circuit so the native liver can be offloaded to provide critical time to receive a life-saving liver transplant or allow their native liver to hopefully recover itself back to health. The CRRT system that will be utilized in our clinical trial have been designed with software updates to accommodate our bioengineered livers and to facilitate liver dialysis. The current generation of these systems is available in most ICUs. and are designed to deliver continuous renal replacement therapy and therapeutic plasma exchange. Our modified CRRT systems were created specifically for our study, and if this study is ultimately successful and Mural Liver ELAP gains approval, the existing installed base of CRRT systems can receive similar software updates to accommodate Mural Liver ELAP and enable the delivery of liver dialysis. Our liver support, our dialysis, has some important differences versus kidney dialysis that I want to highlight. First, liver dialysis is an acute therapy performed once in the ICU, where kidney dialysis is a chronic therapy performed indefinitely in an outpatient center or at home. Again, this is because the liver is the only organ capable of regenerating itself. To perform a mural liver ELAP procedure, one of our bioengineered livers will be delivered to the ICU from our fully integrated manufacturing facility, encased in a disposable chamber and connected to a CRRT device situated near the patient's bedside. We currently envision utilizing one bioengineered liver per treatment. If successful, at a minimum, this would serve as a bridge to transplant, and at a maximum, This could serve as a bridge to recovery where it would not only benefit the treated patient, it could also free up livers for others in need of transplant because today over 50% of ALF patients either die or receive a liver transplant. The impact of mural liver ELAP on the health system could be substantial as 50,000 people in the U.S. die every year from all types of liver failure. And in a typical year, only about 9,000 liver transplants are performed due to the lack of supply. Specific to the addressable market for mural liver ELAP, approximately 80,000 people are hospitalized each year due to a combination of ALF, acute on chronic liver failure, and alcoholic hepatitis. We expect that the initial addressable market for our mural liver ELAP product candidate will be the ALF population, which represents up to 5,000 of the 80,000 hospitalizations I just referenced. While expansion studies would likely be required to address the additional patient population, I want to make sure that people appreciate the potential total addressable market that we can envision for mural liver ELAP. Today, there is no gold standard therapy for ALF, and supportive and symptomatic management are the cornerstones of current treatment. Acetaminophen overdose is the most common cause of ALF in the United States, and there is an effective antidote available that is most effective if given within eight hours of overdose. Other common causes of ALF are mushroom overdose and viral hepatitis, and treatments often include a cocktail of therapies. As you can appreciate from these examples, Without a standard of care, there is significant potential for missing a therapeutic window or lack of a viable therapy. Importantly, mural liver ELAP can be used in combination with other therapies than an ALS patient may be prescribed. The current design of our phase one trial for mural liver ELAP envisions enrolling up to 15 ALS patients. These patients can be on treatment for up to three days and monitored for 21 days thereafter. Our plan is to enroll patients at up to six clinical sites, and we have a good sense of which institutions will likely participate in our Phase I clinical trial. Participating sites will become known after our IND is cleared by the FDA, at which time institutions can begin their internal IRB process. The manageable size of this trial and the fast follow-up leads us to believe that we could have Phase I data in hand within 9 to 12 months of commencing the trial. If successful, we foresee commencing phase two and phase three clinical trials, potentially a combined phase two, phase three trial soon thereafter. We are actively exploring various regulatory and marketing pathways that may be applicable to mural liver ELAP. We anticipate seeking an RMAT designation that would allow us to receive greater interactions with the FDA during development and a priority review designation upon BLA submission. We also anticipate seeking orphan drug designation that would grant us seven years of marketing exclusivity upon BLA approval. Our team will also be turning its attention to pre-commercial activities, such as pricing and reimbursement discussions, due to the potential short duration of these trials. As I wrap up my comments around mural liver ELAP, it's valuable to highlight that our pipeline has always been sequenced so that the development of future product candidates can benefit from the learnings of our prior product candidates. This sequential de-risking strategy started with our first two products that utilized perfusion decelerization to produce hernia repair, and advanced wound care products from porcine livers. Both products received 510K clearance from the FDA and have been safely implanted in thousands of patients and were outlicensed in 2019 so we could focus entirely on organ transplant. The significance of these two products today is that the clinical and regulatory learnings around perfusion decelerization helped us inform certain decisions relating to mural liver elapse. The reason that I leave you with this final thought is that while liver dialysis is an excellent commercial market opportunity on its own, the learning from Mural Liver eLab should also prove valuable towards informing some of the developmental aspects of our fully implantable bioengineered organs because Mural Liver eLab is now the first time we are utilizing perfusion decelerization plus resellerization. Moving on to our fully implantable bioengineered organs, Mural Kidney and Mural Liver. We remain on track to submit our pre-IND requests for both programs in 2023. And similar to Mural Liver eLab, we will have a better sense of timing regarding their paths to the clinic after we receive the FDA responses. As a reminder, we have already achieved very important proof of concepts in both of our fully implantable programs. We published the results of a study in 2021 done in collaboration with the Mayo Clinic announcing the successful implantation of our bioengineered livers into large animals. This study showed valuable proof of concept data for mural liver and also for our entire decelerization and resellerization platform technology. Our kidney team has also delivered exciting news regarding the development of our fully implantable bioengineered kidney. During our second earnings call, I shared that our kidney team successfully demonstrated early urine production and protein retention in our preclinical bench testing. We believe that this is the first time that a bioengineered kidney has produced urine, an important milestone in the development pathway. Fast forward to the third quarter, the same kidney team was selected as a finalist by KidneyX to participate in the Innovation Kidney Winner Showcase at ASN Kidney Week earlier this month. As many of you know, KidneyX is a partnership between the U.S. Department of Health and Human Services and the American Society of Nephrology with a mission to accelerate innovation in the treatment of kidney disease. This is the second time Mural Matrix has been a KidneyX finalist, so a great accomplishment for Mural Matrix. I'd like to specifically acknowledge Emily Beck and our scientific kidney team members for being recognized by such a prestigious organization. Moving away from our pipeline updates, I would like to conclude my portion of this call by sharing a couple of business updates related to strengthening of our IP portfolio and a strategic hire. On the intellectual property front, you may have seen that we recently issued a press release regarding the receipt of a new patent for methods of resellerizing a tissue or organ for improved transplantability. This new patent covers the revascularization of decellularized organs and tissues encompassing all types of organs, including kidneys, livers, lungs, and hearts. This is our 119th issued patent relating to our technology platform in the United States and major markets worldwide. We continue to believe that Mural Matrix possesses the core patents related to perfusion decellularization and recellularization. which is a desirable position for us to be in. On the hiring front, we announced the appointment of Dr. Jack Lake as our new medical director. Dr. Lake brings tremendous expertise and knowledge of liver and whole organ transplantation to our team, which we believe will prove invaluable on multiple fronts. Dr. Lake will be on site one day per week while remaining in his current roles at the University of Minnesota as professor of surgery and medicine the Chief of Hepatology and Executive Medical Director for Solid Organ Transplantation. Dr. Lake brings so many other relevant credentials to our organization that we highlighted in his hiring press release that I would like to encourage you to take a look at. We are delighted to have Jack on our team. I will now turn it over to Jim Douglas, our Financial Officer, to discuss our financial results in the third quarter of 2022. Thank you, Jeff.
