Good afternoon. And thank you for joining us for our first quarter financial results and corporate update call. The first month of this most unusual and challenging year have been a productive time for Capricor. I am pleased to report that we have made significant progress in the midst of the coronavirus pandemic. And, as many of you know, we are not on the sidelines in the fight against this deadly virus. We are working to develop potential treatments and vaccines against COVID-19. Our lean product candidates CAP-1002 is currently being used to treat patients who have COVID-19, under the US FDA compassionate use pathway. I will discuss our efforts against COVID-19 in a few moments. On the call today, I'm going to spend a few minutes discussing CAP-1002 for the treatment of Duchenne Muscular Dystrophy, which are the major focus of this update will be on CAP-1002 as a potential treatment for COVID-19 patients. The rapid progress of our exosome program, which includes our vaccine initiatives, and finally, our objectives for 2020. So first let me update you on some of the company's recent highlights. Yesterday was a momentous day for Capricor, as we released our 12 months data from the HOPE-2 clinical trial. The data was resoundingly positive with P values below the 0.05 level, and multiple measures of upper limb, cardiac and respiratory function, and we believe, it supports accelerated approval. Dr. Craig MacDonald, hosted a call with me to discuss the data and its importance to the DMD community. We plan on presenting this data to the FDA this summer with the goal of accelerating the pathway to approval of CAP-1002 for DMD. I will present highlights and a bit more color on our HOPE-2 data later in this presentation. Regarding our COVID-19 program, on April 29, we announced positive results in six critically ill patients with COVID-19 who were treated with CAP-1002. All of whom are currently alive, and four of whom have been discharged. In fact, one of the patients was recently interviewed on television, ABC7 in Los Angeles on Tuesday, May 12. And they attribute the cells he received to saving his life. A peer reviewed publication in the journal titled Basic Research and Cardiology was published on May 12, which highlights this study, when compared to a natural history group survival in those patients treated with CAP-1002 was markedly increased. Based on the positive data from the compassionate use series, we filed an expanded access IND with the FDA. We now have approval to treat up to 20 more COVID-19 patients with CAP-1002. However, we also submitted a revised protocol this week to add 20 more patients on placebo, so that we can move quickly into a randomized placebo controlled trial. I will elaborate a bit more on COVID-19 and CAP-1002 later in this presentation as well. In the second part of our two pronged approach to COVID-19, we are harnessing our engineered exosome platform to build vaccines for COVID. To that end, on March 26, we conducted a webcast with Dr. Stephen Gould, Professor of Biological Chemistry at Johns Hopkins University, during this time he explained why exosomes are uniquely suited as a platform for vaccine development, whether for infectious disease or oncology, he presented further Capricor's strategic plan to expand and capitalize on the vaccine and therapeutic opportunities of our exosome technology platforms as well. Working with Dr. Gould gives us the ability to develop a novel engineer exosomes pipeline with access to premier academic data and preclinical studies. Now, as you can see, we have had a busy start to this year, and we’ll continue to build on our various programs throughout 2020. But for now, let me give you some additional color on our program. Let's turn now to what is on everybody's mind and what is impacting almost everything we do, which is the coronavirus commonly called COVID-19. This virus is causing so much sickness, death and economic and financial destruction to the United States and the world. We have never seen anything that has had such a tremendous impact on our daily lives, and which has so drastically disrupted the way we live and work. We at Capricor have taken this pandemic by the hand. As I mentioned a moment ago, we were taking a two pronged approach to COVID-19. On the one hand, we are using CAP-1002 our self therapy product, which as you know, is a late stage clinical development for Duchenne Muscular Dystrophy to treat the cytokine storm, which occurs in a later stage of the illness. On the other hand, we are developing our exosomes to be used as a vaccine platform to potentially prevent COVID-19. Using CAP-1002 to treat COVID is a case of serendipity favoring the prepared mind. Over 100 papers have been published on the bioactivity of the CDCs the main components of CAP-1002 and we have shown that CDCs released exosomes as well as anti-inflammatory cytokines, those that attenuate inflammation in a variety of disease models of profound inflammation, including sepsis, thrombo related stock shock, [indiscernible] disease and other autoimmune diseases. We decided to use CAP-1002 in COVID, because the pathogenesis of the disease is a viral phase in which the virus attacks the body, and causes symptoms which are ever emerging, as we all hear daily in the popular press. In some people, the virus leaves and the person recovers without the color. However, there is a subset of people in which the terror created by the virus over stimulates the immune system and the person develops a cytokine storm or post inflammatory responses. Paradoxically, our own immune systems can do more harm than good in these situations, and trigger a whole host of inflammatory responses. Based on such strong preclinical and clinical data, we decided to offer CAP-1002 to patients with critical COVID related ARDS acute respiratory distress syndrome for a compassionate use protocol. To remind you, a series of six critically ill patients were treated with 150 million cells, the same dose that we are using in DMD. Two of the patients received two doses one week after the first dose. As of today, we currently have a 100% survival rate and four patients have been discharged from the hospital. Two of them remain in the ICU, but are clinically stable. Now, as I mentioned a few moments ago, earlier this week, along with our colleagues at Cedars-Sinai Medical Center, we published a paper in the journal Basic Research in Cardiology, which was peer reviewed, detailing the patient's trajectories following the cell treatments. In order to evaluate whether those treated with CAP-1002 had a different outcome to those that were untreated. The data from the six were compared to a group of 34 patients from the same hospital, who did not receive CAP-1002. The treated patients did much better as the untreated patients had a mortality rate of 18% versus our 100% survival to date. Additionally, in this series of patients, and as noted in the publication, laboratory biomarkers correlated with poor outcomes were measured in all patients prior to cell delivery. Following infusion, several patients showed improvements in these biomarkers such as ferritin, absolute lymphocyte counts, and C reactive protein was maybe important in recovery from the cytokine storm. No adverse first release events related to the administration of CAP-1002 were observed. We were so encouraged by this preliminary clinical data that we submitted an IND with the FDA for expanded access to treat up to 20 additional COVID-19 patients, which has been approved. We expect to begin enrolling patients into this program soon. We also submitted a revised protocol this week to add 20 placebo patients and move immediately into the randomized placebo controlled portion of the trial to treat patients with severe to critical disease. This is of course subject to approval by the FDA. Based on the global concerns surrounding COVID-19, we hope to find at least part of this program with non-diluted funding for which we are now applying. Now please stay tuned for updates on this very important program. As we all know, if the cells continue to look promising, they could offer hope for hundreds of thousands if not millions, of people. Now let me turn your attention to Duchenne Muscular Dystrophy. As I mentioned, yesterday was a momentous day for Capricor. Based on the strength and value of the data from our HOPE-2 trial. We are getting calls from around the world from parents anxious to get CAP-1002 for their children with DMD. The data was perhaps the best ever seen in DMD studies with multiple areas of functional improvement in treated versus the placebo patients. To our knowledge, improvements in multiple areas of muscle function, including cardiac muscle, such as seen in HOPE-2 have never been reported before. The only other positive data which has shown such profound effects are steroids and remember, steroids may negatively impact cardiac function, not improve it. We are energized by the data and are laser focused on our goal to bring CAP-1002 to patients with Duchenne Muscular Dystrophy. Let me also remind you that all of our patients were steroids treated. So the effect of cells was on top of all standard of care medicines, including any of the exosomes skipping drugs for which they qualified. We already know DMD as the genetic disorder that causes muscle degeneration due to the lack of dystrophin, which is a protein in the muscle fiber membrain. The lack of discipline causes muscle damage, and makes them unable to function properly and also produces inflammation, which is responsible for the muscle deterioration of skeletal and cardiac muscle. But DMD ultimately leads to an untimely demise, unfortunately at an average age of 27 with up to 40% of them related to heart failure. The HOPE-2 trial treated DMD participants who were mainly non-agilent, these are boys and young men older than 10 years of age. Boys with DMD lose their ability walk between the ages of 12 and 15. Patients are living longer with DMD due to steroid therapy, and by the age of 18, 70% of patients with DMD have depressed heart function. We presented the top line data from the 12 months final data set from HOPE-2 yesterday. We were very pleased with the data which we believe may offer real hope to the patients with advanced stages of DMD. The data is the first of its kind as I said, because it is the first opportunity to treat skeletal and cardiac muscle dysfunction that comes from DMD. And it's harder to those later stage patients for which no current therapies exist. The data was very strong with multiple measures of cardiac and upper limb function achieving P values, that suggests very little of the data could be due to chance. Furthermore, these patients are not typically eligible for the current gene therapy trials and there are a lot of misgivings that gene therapy may not work well in the highly fibrotic tissue that occurs in the older boys. Now there are a few things that I would like to put in to context. Originally HOPE-2 with power to detect a one point difference in the performance of the upper limb commonly called the PUL 1.2 mid-level, which is essentially the use of the arm. But in discussions with the FDA, they have now recommended that we use the full PUL and the newer, better calibrated version of the test the 2.0 as a primary efficacy endpoint to support registration. So although we perform the analysis using the PUL 1.2 version, we also perform the analysis using the PUL 2.0 and consider this the most important findings of this study. And to that end, you can see we have a P value of 0.05 in the full PUL. In the full PUL, which is what most clinical trials monitor achieve. Now we also came very close to significance in the PUL 1.2 mid-levels with all of the data included. We also showed very strong P values in measures of global cardiac function, never before seen in DMD, but the ejection fraction and volumes improving over the one year trial period. Taken together this data set is very strong and suggest treatment with CAP-1002 clinical outcomes in DMD. Now, I gave you a preview of the data that I was planning to present now, which I find very compelling. And I'm sure you will too. You see we noticed that every parameter that there was one treated patients with an outlier commonly a non-responder. He is included in every analysis that we have presented, but I wanted to understand more about him and why he might not have responded to the treatment. What we found was that he did not respond to steroids either. He was non-ambulant before the age of 10, which is extremely uncommon in the era of steroids. And he had several other health issues that might have prevented him from responding. Dr. MacDonald told us yesterday that it is not uncommon that there is a 60% non-responder rate. So the fact that we had one is not surprising, and in fact, suggests that the data has a very, very strong balance and a strong treatment effects. So let's see what happens when we remove them from the data analysis. Shown here, the mid PUL 1.2, the originally stated primary efficacy endpoint for the fully enrolled study. The P value is 0.08, which is very good for an orphan disease and can stand on its own merits. But look what happens when our non-responder shows up we have a highly significant P value, which suggests a strong treatment effect and hence efficacy. We consider this to be very important data to present to the FDA. Similarly, look at the full PUL 2.0. The endpoint suggested by the FDA to support approval. Even with a non-responder included we achieved what wouldn't be considered statistical significance at P equals 0.05. But look again at what happens when we pull it out of the analysis and unequivocal sign of efficacy with a P value of 0.004. Again, we will take the status of the FDA in support of our requests for approval. Now, our goal is to convince the FDA that this therapeutic needs to be approved with a confirmatory study to follow and we plan on starting that discussion this summer. We respect the FDA process and welcome the opportunity to share our exciting data on the PUL 2.0 and other data with the FDA. Now last but not least, let's turn our attention to an update on our exosome technology. Our first mission is to develop vaccines using the exosome as the platform. Obviously, we chose COVID-19 as our first target, based on its current place in global health risks, and the need for medication. As we announced earlier this year, we have retained Dr. Stephen Gould of Johns Hopkins University and his laboratory to assist us in developing our engineered exosome platform. We did not have internal capabilities to conduct the primary research necessary for determining a viable vaccine product candidate. But we have a lot of expertise in terms of product development, and early stage manufacturing of cell based biologics. Bringing Dr. Gould in as an executive consultant and collaborating with his labs to develop exosomes was the best way to move this program forward quickly. Briefly on Dr. Gould's background, in case you missed it. He is a professor of biological chemistry at Johns Hopkins University, where he directs the research laboratory dedicated to understanding the biology of exosome, especially in the context of human disease, while also serving as the Director of Johns Hopkins University graduate program in biological chemistry. Dr. Gould is Co-Founder and acting President of the American Society for exosomes and micro vesicles. On March 26, we held a webcast hosted by Dr. Gould that was informative, interesting and educational for all who are on the webcast. The replay is still available on our corporate website. I hope you can find time to listen to Dr. Gould's presentation. I believe you will find it worthwhile. I will provide you with some of the key points that Dr. Gould made on the webcast that clearly showed the advantages of our exosome technology and why we believe that it is uniquely suited for the development of vaccines and treatments. First, as we've been talking about for a while, exosomes are small secreted single membrane particles. They're approximately 30 to 150 nanometers in size, and highly enriched in selected proteins, lipids, nucleic acids and glycoconjugates released by all cells are abundant and bio fluids. Exosomes have the potential to be excellent delivery vehicle. Normally, concentration falls dramatically over distance. However, concentrations honor in exosomes remain constant, allowing enhanced signaling from a single molecule, multi-dimensional signaling and biochemical pathways. Exosomes accumulated sites of vascular leakiness, which of course includes sites of inflammation, tumors and infections. This is an advantage for exosomes since the vascular permeability and is limited in most tissues. Vascular permeability is very high, as I said, infection wounds decisive inflammation, as I said a moment ago. Now most vaccines are comprised of purified recombinant proteins, live attenuated agents, kill pathogens or antigens and coding DNA. Well, these other approaches are effective against many viruses, immunization with recombinant proteins and DNA often yield relatively weak protection against infection, while immunization with killed virus or live attenuated strains poses health risks for both vaccinated individuals and those who produce the vaccine. Utilizing our exosome technology provides the opportunity to develop vaccines against newly emerging infectious disease such as COVID-19 without risk of infection. We are developing two vaccine platforms in our collaboration with Dr. Gould. One is a tripartite exosome among mRNA vaccines, its formulation is designed to elicit a protective, long lasting immune response to SARS-CoV-2 by targeting all four structural proteins of this virus. This vaccine includes portions of the spine approaching the F protein, which we've heard so much about, but also the N protein which is the primary target of protective immune responses in COVID-19 patients. The M or membrane protein and the E or envelope protein. Furthermore, Capricor mRNA expressed these antigens and forms that are designed to induce a balanced humeral and cellular response that has the potential for long lasting protection against SARS-CoV-2. The other is called an exosomal antigen vaccines, which is vesicle based nucleic acid free formulations, turn all structural proteins against SARS-CoV-2. These are often referred to as VLP virus like particles. These extracellular vesicles have the size range of exosomes and are produced by the same process pioneered by Capricor in this study of cardiosphere-derived cells currently used to treat COVID-19 patients. And [indiscernible] the native composition of SARS-CoV-2 virus particles that is non-infectious and virus free and can be produced at scale by industry standard techniques. We already have exciting cell based data on these two candidates and expect to be an animal studies very soon. While there are many vaccines in development, we believe that the combination of the exosomes, the four proteins, and Dr. Gould's 20 years in the field could offer a unique opportunity for the potential novel vaccine. I tell my team regularly, David slew Goliath. For this reason, we are exceedingly bullish about our vaccine program. In addition, everything we are doing in developing vaccines may be potentially applied a platform technology for other indications. I will now turn our call over to AJ Bergmann, our CFO.
