Thanks, Joe. This quarter, I’ve decided to start my detailed comments a little differently. As I have done historically, I will provide a summary of our CD34+ technology platform effectively the general reason to believe and then we’ll follow that with specifics on each product development program. But this time, I’m going to start with a simpler and more high level description of what we are doing and why it should be considered so relevant and attractive. As many of you are probably aware, most companies in the cell and gene therapy space are focused on treatments for cancers and/or rare diseases. While there is clearly a need for advances in these areas, it seems to have been overlooked that heart disease not only remains the leading cause of death in the U.S., but is in fact increasing. It goes without saying that the pharmacoeconomic burden of heart disease also remains large and growing. So one of the factors that makes Caladrius Biosciences different is that we are focused on developing therapies for the number one disease killer, cardiovascular disease. Also differentiating us from many autologous cell therapy companies working in any therapeutic category is the fact that we have late-stage clinical programs with a large database of human clinical data. In short, our therapies to date have been shown to be safe, effective, durable, economical as pharmacoeconomically justified. And finally, we are working on products with the goal of providing patients with a curative therapy rather than one that just manages symptoms over their lifespan. So with that said, now let me provide a summary of the basis for our CD34+ cell therapy platform. To repeat my comments from previous quarterly calls, our CD34+ cell technology has led to the development of therapeutic product candidates designed to address diseases and conditions caused by ischemia, a condition in which the supply of oxygenated blood to healthy tissue is restricted. Previously published animal and human studies have demonstrated that the administration of CD34+ cells induces angiogenesis of the microvasculature, that is that these cells prompt the development of new blood capillaries thereby contributing to the prevention of tissue death by facilitating blood flow to the area of ischemic insult. We believe that several conditions caused by underlying ischemic injury can be improved through the application of our CD34+ cell technology, including but not limited to critical limb ischemia, coronary microvascular dysfunction and refractory angina. And now to the specifics of our three CD34 development programs, beginning with our CD34+ cell therapy product nearest to commercialization, CLBS12 in Japan. Among others, our CD34+ cell technology has spawned the development of CLBS12, a product candidate for the treatment of critical limb ischemia, which is currently in an ongoing registration eligible clinical study in Japan. CLI is a severe obstruction of the arteries that significantly reduces blood flow to the lower extremities, principally the feet and legs and represents the end stage of peripheral arterial disease. CLI patients often experience severe rest pain, limited mobility, non-healing skin ulcers, and if not successfully treated, eventual amputation. Please note that it is a well documented, but not well known fact, the CLI patients have a higher mortality rate than patients with most cancers. As a reminder, CLBS12 was previously awarded a SAKIGAKE designation from the Japan Ministry of Health, Labor and Welfare for the treatment of CLI. Importantly, the SAKIGAKE designation is akin to an RMAT designation in the United States and affords the recipient prioritized regulatory consultation, a dedicated review system to support the development and review process as well as reduced review time of six months for the CLBS12 registration application once filed. Additionally, CLBS12 is eligible for early conditional approval and possibly full approval based on the compelling nature of the complete dataset from a ongoing prospective randomized controlled open-label multicenter study in CLI patients in Japan. The ongoing study comprises subjects divided into two cohorts, a 30-subject group with traditional arteriosclerotic CLI and a six-subject group with Buerger’s disease, a specific type of CLI often associated or exacerbated by heavy smoking. Those subjects who are randomized to treatment are dosed with CLBS12 through intramuscular injection in addition to receiving standard of care pharmacotherapy. Subjects randomized to the control arm only receive standard of care with drugs approved in Japan, including antiplatelet agents, anticoagulants and vasodilators. The choice of which is made by the investigators according to the protocol. The study allows for the rescue of subjects in the control arm by indicating the crossover to treatment if their CLI is deemed to be progressing. The primary objective of the study is to show that CLBS12 can prevent the serious consequences of CLI by reverting the patients to a CLI-free condition through improved blood flow in the affected limb. CLI-free status is defined as two consecutive monthly visits in which rest pain is absent and previous non-healing skin ulcers are completely healed as determined by independent adjudication committee. As previously reported, and as you can review in our corporate presentation on our company website, the responses observed to date in the fully enrolled Buerger’s disease cohort are very positive and consistent with the beneficial therapeutic effect and safety profile as reported by previously published clinical trials in Japan and the U.S. In Buerger’s disease, where amputation and often death are likely outcomes and where no available pharmacotherapies prevent amputation, we are thus far observing a 50% remission rate with two patients still in follow-up. It is worth emphasizing that the natural history of Buerger’s disease patients is continued disease progression leading to likely amputation, so our data are extraordinary. We are very encouraged by these early results and believe that they suggest a positive outcome for the overall trial, recognizing however that the final conclusion of the trial will be dependent on all data from all subjects. We expect to report data from the completed study in late-2020 or very early in 2021. Regarding commercialization, our strategy remains to license or partner CLBS12 in Japan. And to that end, our conversations continue with prospective partners and we continue to seek to consummate a deal in concert with the completion of the study if not before. As I highlighted on our second quarter call, the European Medicines Agency recently granted the advanced therapy medicinal product classification to CLBS12 for the treatment of CLI. Advanced therapy medicinal products are defined as medical treatments that are based on genes or cells and are intended as long-term or permanent therapeutic solutions to acute or chronic human diseases at a genetic cellular or tissue level. This regulatory achievement sets the stage for us to work closely with European regulators to define the most expeditious development and regulatory plan for registration of CLBS12 in EU. And finally, we recently received notice that FDA did not award CLBS12 in RMAT designation. However, the agency did indicate that we should consider reapplying in the future once more clinical data is available to support the application. Turning now to our CD34 product candidate as a treatment for coronary microvascular dysfunction. Like all our CD34+ cell therapy development candidates, CLBS16 uses a proprietary and patented formulation of CD34+ cells, specifically designed for an injection at or near the site of ischemic insult, which in the case of CMD, is an infusion into the coronary artery. CLBS16 is currently being studied in the ESCaPE-CMD trial, a 20 patient proof-of-concept clinical trial evaluating CLBS16 as a treatment for coronary microvascular dysfunction, a plaque with heart disease involving damage to the inner lining of the tiny arterial blood vessels in the heart with no discernible large vessel blockages. Despite the absence of large vessel disease, CMD patients have an equally poor prognosis related to major adverse cardiac events and depth as do patients who have identifiable large vessel blockages. But because obvious large artery blockages aren’t seen, CMD is often underdiagnosed, misdiagnosed or untreated. It should also be noted that CMD is more frequently encountered in females making this an important emerging women’s health care issue. CLBS16 is designed to address the symptoms and physiology of CMD by employing the CD34+ cell innate ability to increase microcirculation. Similar to the results of our CLI study in Japan, the initial data observed in the ESCaPE-CMD open-label study comprising those subjects who have reached the six months follow-up visit are extremely encouraging. We’ve previously released the results from about one-third of the patients and indicated that we are observing a highly statistically significant improvement in coronary flow reserve, a direct measure of cardiac muscle perfusion along with a corresponding improvement in clinical symptoms. In the near future, we will augment those results with the results of the six-month follow-up on 17 of the 20 patients as they will be presented by Dr. Noel Bairey Merz, Director of the Barbra Streisand Women’s Heart Center at the Cedars-Sinai Smidt Heart Institute in Los Angeles. During the American Heart Association’s 2019 Scientific Sessions on November 16, 2019. The results of the ESCaPE-CMD trial are not only important for defining the next development step for CLBS16, but they provide the first direct quantitative evidence in humans corroborating the mechanism of action of CD34+ cells, something which is supportive of all of our programs, especially CLBS14. We are looking forward to reporting top line data from the full compliment of patients at the end of 2019 or in early 2020. Assuming that the full dataset corroborates the previously reported results, we are planning to advance the program to its next clinical development step as expeditiously as possible. And now moving to our CD34+ cell therapy product candidate in the U.S. CLBS14. CLBS14 is being developed to address no option refractory disabling angina by stimulating the growth of new microvasculature in an oxygen-deprived heart in those patients who have had large vessel disease treated with all available therapies, but still have debilitating angina, likely due to a microvasculature deficiency. Our confidence in this program is based on a series of published Phase 1, Phase 2, Phase 3 study results that indicate a consistency of therapeutic effect of CD34+ cells to increase exercise tolerance, improve heart function, and decrease long-term mortality associated with the condition. As previously reported, we finalize the protocol design for confirmatory Phase 3 trial to support the registration of CLBS14 for NORDA in the U.S. However, due to the projected study costs, we have decided to defer initiation of the Phase 3 study in the U.S. at this time. We will proceed with the study once we have acquired sufficient capital to give us confidence that we will be able to fund the study to completion. And among the possible sources of capital that are being investigated are non-dilutive grants and/or partnerships, both of which are being pursued vigorously. So in closing, once again Caladrius continued to make notable progress against our operating plan and we are pleased to have accomplished the goals we established for the past quarter. Our experienced and expert team remains committed to the efficient and effective advancement of our programs as we work to bring innovative treatment options to patients in need and to restore human health. And with that overview, operator, we’re ready to take questions.
