Thank you Wa’el. I will begin with a brief review of our Alzheimer's disease program and the top line results we recently presented from our Clear Mind Study. Based on the growing body of preclinical and clinical data from various sources, we believe Lomecel-B may prevent the clinical progression of Alzheimer's disease by reducing disease related brain inflammation. Neuronal cell death caused by earlier and substantial neuro-inflammation is a significant contributor to the pathogenesis of Alzheimer's disease. In preclinical models of Alzheimer's disease, MSCs with characteristics similar to Lomecel-B has been shown to cause the blood brain barrier, potentially with anti-inflammatory effect, improving endothelial function and promoting neurogenesis, the process of neuron formation in the brain. Our Phase 2A trial of Lomecel-B for mild Alzheimer disease called the Clear Mind Trial completed enrollment in November of 2022. Clear Mind is a 48 patient forearm parallel design, randomized clinical trial of Lomecel-B designed to evaluate the safety of single and multiple infusions of two different dose levels of Lomecel-B compared to placebo in patients with mild Alzheimer disease. The primary endpoint is safety as measured by the occurrence of serious adverse events within the first 30 days after administration of Lomecel-B. Secondary and exploratory endpoints include measures of cognitive function, fluid, and radiological biomarkers relevant to inflammation and the failure of vascular systems. In a previously completed Phase 1 study, we demonstrated a preliminary safety of Lomecel-B patients with mild to moderate Alzheimer disease. Results from Clear Mind show that the primary endpoint of safety was met based on statistical and medical assessment. There was one serious adverse event reported on each Lomecel-B treatment group and none on placebo. Each SAE was reviewed and assessed by the data and Safety Monitoring Board with no safety issues raised. The study of safety data were consistent with established safety profile with no incidents of hypersensitivities, no cases of Alzheimer related emerging abnormalities, no clinically asymptomatic micro hemorrhages as relevant by relief -- revealed by the magnetic MRI, and no notable changes in laboratory evaluations and electrocardiogram. In the secondary endpoint of change from baseline to week 39 in CAD, which is the Composite Alzheimer Disease score, positive results were demonstrated at the pre-specified statistical level of P less than 0.12 [ph]. Statistically significant improvement in weeks 39 in CAD was observed for Lomecel-B at dose level of 25 million with statistical significant 0.091 versus placebo and the pro- Lomecel-B group consists of 25 million dose once, 25 million dose four, 100 million cells four doses with statistical significance 0.099. In terms of specific components of the CAD score compositing point evaluated at P level of 0.052 tails Lomecel-B dosed 25 million once demonstrated statistical significant slowing of disease progression in left hippocampal volume with statistical significance 0:15 [ph] related to placebo. ADCS ADL score, which stands for Alzheimer Disease Cooperative Study activity of daily living and left hippocampal volume at week 39 was statistically significant for Lomecel-B treatment group relative to placebo with P value 0.047 and 0.38 respectively. Other doses demonstrated numerical slowing and prevention of disease worsening relative to placebo in composite score, that’s cognitive score, cognition and function scale, and activity daily living scale measured by the caregiver and left hippocampal volume at week 39. We believe this results provide important validation of both the safety and therapeutic potential of Lomecel-B in the treatment of Alzheimer's disease and provide a robust support for additional clinical trials and other indications. As Wa’el mentioned, we expect the full dataset from this trial in the coming weeks. Now for an update on our HLHS program. For those who might not know, HLHS is a rare congenital and devastating birth defect in which the left ventricle of the heart is either severely underdeveloped or missing. The condition affect approximately a thousand babies per year in the United States. Babies born with this condition have severely diminished systemic blood flow, which requires children to undergo a complex three stage heart reconstruction surgery process over the course of the first five years of their life. While these children can now live into adulthood with surgical intervention, only 50% to 60% of affected individuals survive to adolescence due to right ventricle failure, which is often unable to handle the increased load required to support systemic circulation. Furthermore, even those children, the successful surgical intervention are at an elevated risk of short-term mortality, delayed development and long-term complications including organ failure. As such, there is an important unmet medical need to improve right ventricle function in these patients to improve both short-term and long-term patient outcome. As Wa’el mentioned, we are presenting the latest long-term survival from our ELPIS I study, a Phase 1 study of Lomecel-B in children with HLHS at the scientific session of the American Heart Association, which begins tomorrow. 10 patients participated in ELPIS I trial during which Lomecel-B was injected concurrent with Stage II surgery, also known as a Glenn procedure. In the dataset we are presenting, 10 patients have been monitored for up to five years after treatment. Earlier long-term follow-up data from this trial was announced previously showing that 100% of the 10 patients who participated in ELPIS I trial survived and remain heart transplant free for up to five years of age as compared with the historical clinical trial results showing that children with HLHS who undergo the Glenn procedure typically have had 15% to 20% mortality by five years of age. The ELPIS I data are highly encouraging and reinforce our enthusiasm for Lomecel-B as a potential treatment to transform care for patients with HLHS. Our ELPIS II trial is designed to assess the potential of Lomecel-B to improve right ventricular function and long-term outcomes. The trial is a 38 patient controlled Phase 2 clinical trial evaluating the safety and efficacy of Lomecel-B as an adjunct therapeutic to standard of care HLHS surgery. The primary outcome measure is the change in the right ventricular ejection fraction from baseline to 12 months. The trial is funded by a grant from the National Institute of Health, NATIONAL HEART, Lung and Blood Institute. As we announced this week, our ELPIS II trial has exceeded its enrollment threshold of 50%. We also announced the activation of our eighth clinical site location, one more than the seven originally planned. Completion of ELPIS II is our priority program and our focus is on completed enrollment in this trial in 2024. I will conclude with a brief update of our Aging-Related Frailty program. Aging-Related Frailty is an age associated decline across multiple physiological system leading to the inability to cope with stressors. It is characterized by mobility impairment, weakness, fatigue, weight loss, slowness, and low activity, and puts individual at high risk for poor clinical outcome such as infections, falls, fractures, hospitalization, and even death. At Longeveron we've been evaluating the effect Lomecel-B may have on health and function of elderly frail patients, particularly on the physical and immune system function. With clinical development strategy in Aging-Related frailty in focus on Japan, a country with one of the oldest population in the world. Our Phase 2 clinical trial evaluating Lomecel-B in patients with Aging-Related Frailty in Japan, the Phase 2 trial is a three arm parallel design, randomized, evenly split one to one to one of placebo, as well as two different Lomecel-B infusions. Enrollment is continued and the trial is expected to enroll 45 patients by the end of 2024. The primary endpoint is to evaluate safety with an overarching goal of providing support for an eventual limited approval under the Japan Act of the Safety and Regenerative Medicine or ASRM, which recognizes the tremendous potential -- therapeutic potential of cell therapy. With that, I'd now like to turn the call over to Lisa Locklear, our CFO to discuss our financial results for the third quarter of 2023. Lisa.
