Thank you, James, and good afternoon, everyone. I will begin by providing a high-level summary of what we are doing at Lisata and why we believe our development programs are an increasingly relevant and attractive investment opportunity today. Before that though, I'd like to reiterate our motivation to translate our expertise and unique scientific approach into clinical trials, which could lead to treatments for patients most in need. Lisata's pipeline is built on a portfolio of proprietary and patented technology that is grounded in strong scientific rationale to identify and treat patients most likely to respond to our targeted therapies. We appreciate the critical importance of generating meaningful clinical data to validate our platform technologies and create shareholder value, and our entire team is focused on accomplishing this quickly, cost effectively, yet rigorously. With that, I will now provide a summary and status update for each of Lisata's clinical development programs, kicking off with our lead product candidate, LSPA-1, for the treatment of advanced solid tumors in combination with other anticancer agents. Despite advances in cancer therapy today, many solid tumors remain difficult to treat, many solid tumors, including pancreatic cancer, gastric cancer and other solid tumors are surrounded by dense fibrotic tissue known as stroma that limits the efficacy of current chemotherapies for the treatment of a variety of advanced solid tumors. Many tumors also exhibit an immunosuppressive tumor microenvironment, or TME, which suppresses a patient's immune system's ability to fight the cancer and therefore, can limit effectiveness of current therapies. These factors negatively impact the ability of many cytotoxic agents and immunotherapies to effectively treat these cancers. To address the tumor stroma role as a primary impediment to effective treatment, Lisata's approach is to activate the CN rule or CendR natural transport system that normally brings nutrients into a tissue under emergency situations such as an injury. Tumors hijack this system to promote their growth. Lisata's lead candidate, LSPA-1, formerly known as CEND-1 is an investigational drug that actuates the CendR active transport mechanism while also having the potential to modify the tumor microenvironment and make it less immunosuppressive. LSPA-1 targets the tumor vasculature by AFINiTY for Alpha-B beta 3 and beta 5 integrins that are selectively expressed in tumor vasculature but not healthy tissue. LSPA-1 is a specific cyclic internalizing RGD peptide that once bound to these integrins is cleaved by proteases expressed in tumors to release a peptide fragment called CendR fragment, which then binds to a second receptor called Neuropilin-1 to activate a novel uptake pathway that allows anticancer drugs to more selectively penetrate solid tumors. The ability of LSPA-1 to modify the tumor microenvironment to enhance delivery and efficacy of co-administered drugs, has been demonstrated in a range of preclinical solid tumor models. These results come internally from Lisata and from collaborators and research groups around the world and have been the subject of over 200 scientific publications. Along with our collaborators, we have amassed significant nonclinical data demonstrating enhanced delivery of a range of emerging anticancer therapies including immunotherapies and RNA-based therapeutics. Clinically, LSPA-1 has demonstrated favorable safety, tolerability and activity in clinical trials to enhance delivery of standard of care chemotherapy for pancreatic cancer. We are exploring the potential of LSPA-1 to enable a variety of treatment modalities to treat a range of solid tumors more effectively. Currently, LSPA-1 is the subject of a Phase Ib/IIa and IIb clinical studies being conducted globally in various solid tumors. These include metastatic pancreatic ductal adenocarcinoma, colorectal cancer and appendiceal cancers in combination with a variety of anticancer regimens. Additionally, the evaluation of LSPA-1 administered in combination with corresponding standards of care in advanced solid tumors in a Phase II placebo-controlled basket trial is planned to initiate in the first half of 2023. As Dave Mazzo mentioned earlier, the FDA provided us with guidance on the requirements for a pathway to registration in the U.S. for LSPA-1 in metastatic pancreatic adenocarcinoma or as we refer to it as mPDAC. We have subsequently shared this feedback with our global partners and are now finalizing development programs and individual study protocol modification to address FDA's recommendation. Turning now to LSPA-12 or HONEDRA in Japan, our product candidate for the treatment of critical limb disease -- excuse me, critical limb ischemia, or CLI, and Buerger's Disease. HONEDRA was awarded a SAKIGAKE designation from the Japanese regulatory authorities for the treatment of CLI and Buerger's Disease, which is an orphaned size subset of CLI. The SAKIGAKE designation is akin to a regenerative medicine advanced therapy designation or an RMAT designation in the United States. SAKIGAKE designation affords the recipient prioritized regulatory consultation, a dedicated review system to the development and review reverification operable registration Commission as well as reduced review time of registration locations filed. Additionally, under Japan's Regenerative Medicine legislation, products such as HONEDRA are eligible for early conditional approval and possibly full approval in Japan based on the assessment of the data from the trial or trials designed in direct collaboration with the Japanese Pharmaceuticals and Medical Devices Agency, or PMDA. Note that conditional approval of a regenerative medicine product only requires the demonstration of a trend toward therapeutic effect, together with acceptable safety. Further, the SAKIGAKE designation is a highly sought regulatory classification in Japan, and we hope that this coupled with positively trending data from our trial will make HONEDRA an attractive product for partnering to a Japanese pharmaceutical company. Data from the follow-up of all patients treated in the company's registration eligible study of HONEDRA in Japan for the treatment of CLI and Buerger's Disease are consistent with our expectations of therapeutic effect and safety based on previously published clinical trials data generated in Japan and the United States. These data have been compiled and are the subject of discussions with the PMDA as part of the Japanese regulatory pre-consolidation process and in preparation for the formal consultation meetings, which preceded the Japanese new drug application. If successful in the pre-consultation process Lisata expects formal clinical consultation to occur by midyear 2023. Concomitantly, the company continues its efforts to secure a Japanese partner to complete the remaining steps to produce registration in Japan. Moving on to XOWNA or LSPA-16 for the treatment of coronary microvascular dysfunction, or CMD. Coronary microvascular dysfunction is a disease that continues to be under-diagnosed and potentially afflicts millions annually, a vast majority of whom are female with no current treatment options. In May of 2020, Caladrius announced the full data results from the Phase IIa ESCaPE-CMD trial, showing a highly statistically significant improvement in coronary flow reserve correlating with symptom relief for patients with CMD after a single intracoronary injection of XOWNA. Subsequently, the company initiated a rigorous Phase II clinical trial known as the FREEDOM trial, which, to our knowledge, is the first controlled regenerative medicine trial in CMD in the United States. The FREEDOM trial was a double-blind, randomized, placebo-controlled trial designed to corroborate the results of the ESCaPE-CMD trial while assessing the efficacy and safety of delivering autologous CD34 cells our XOWNA product to subjects with CMD and without obstructive coronary artery disease. Unfortunately, and as previously reported, the COVID-19 pandemic in the United States at both a direct and indirect impact on FREEDOM, which made enrollment much slower than originally predicted and challenging to accelerate. As a result, the company suspended trial enrollment and conducted an interim analysis of the data. Following this analysis and along with key opinion leaders input, the company has determined that execution of a redesigned FREEDOM-like trial would be the appropriate next step, but the cost of such a trial would be prohibitively expensive to undergo without a strategic partner. Thus, XOWNA development will only be continued as a strategic partner that can contribute the necessary capital for future development is identified and secured. Lastly, LSPA-201 for the treatment of diabetic kidney disease, or DKD. The company initiated a Phase Ib open-label, proof-of-concept trial evaluating LSPA 201, a CD34 positive regenerative cell therapy investigational product for intrarenal artery administration in patients with diabetic kidney disease. This development program focuses on patients that exhibit rapidly progressing Stage IIIb or IV disease. The scientific rationale for the program is based on the association of progressive kidney disease with attrition of the microcirculation of the kidney. Preclinical studies in kidney disease and injury models have demonstrated that protection or replenishment of the microcirculation results in improved kidney function. Our proof-of-concept protocol provided for a staggered sequentially dosed cohort of 6 patients overseen by an independent data safety monitoring board with the objective of determining the tolerance of intrarenal cell therapy injection in diabetic kidney disease patients as well as the ability of LSPA-201 to regenerate kidney function. A key readout of data will occur at the 6-month follow-up visit for all patients. The first patient was treated in the study of LSPA-201 in April 2022, and followed by completion of enrollment of all 6 subjects in July 2022. We continue to anticipate top line data from all subjects by the first quarter of 2023. With that, I will now turn the call back to Dave.
