Thanks Joe. I’ll begin my brief business review with a repeat of the news we released this morning announcing the appointment of Ms. Cynthia Schwalm, Former President and CEO of Ipsen North America as the newest member of our Board of Directors. Cynthia brings extensive experience in leading and managing biopharmaceutical companies during transformative years of growth and we are delighted to have her join our Board. We believe she will offer a fresh perspective on making important contributions to our strategic and operational plan, particularly with respect to the commercialization of our products. We look forward to our guidance as we continue to advance our clinical programs through late-stage development and toward registration and eventual launch. Let me now turn to a discussion of advances in our development programs beginning with those based on our CD34 positive cell therapy platform. To those who have listened to my previous calls, I apologize for the redundancy of some of my remarks. But for the growing list of newcomers joining our calls, it is vital that we provide the rationale behind our platforms. Heart attack, congestive heart failure, angina, critical limb ischemia and stroke are often caused by an acute or chronic deficit in the supply of oxygenated blood. This deficit is typically due to disease in the large and small blood vessels or capillaries that serve the target tissues. Historically, the clinical focus of treatment has been on strategies to address the problems in large vessels leading to the use of clotbusting drug, angioplasty and stents to treat heart attack and percutaneous and surgical revascularization for chronic ischemic conditions. Yet to-date, no therapy has been designed specifically to address the defects in the small blood vessels which contribute to the overall impairment of patients with acute and chronic ischemia. We have long being known that one of the body’s responses to coronary disease is the recruitment of CD34 positive cells to ischemic tissues. These cells which reside naturally in the bone marrow are preprogrammed to repair damage to the small blood vessels or microcirculation in all tissues. CD34 positive cells have been shown to induce angiogenesis where the development of new blood vessels, thereby contributing to the preventing tissue death by facilitating blood flow. At Caladrius we are now advancing three proprietary CD34 positive cell therapy development programs, namely, CLBS12 as a treatment for critical limb ischemia, CLBS14-CMD for the treatment of coronary microvascular dysfunction and CLBS14-RfA for the treatment of refractory angina. Let's start with CLBS12, our proprietary CD-34 technology specifically formulated for intramuscular administration for the treatment of lower extremity ischemia. As I've explained previously, critical limb ischemia is a severe obstruction of the arteries that significantly reduces blood flow to the extremities, principally the feet and legs and represents the end stage of peripheral arterial disease. CLI patients often experienced severe rest pain, limited mobility, non-healing skin ulcers, and if not successfully treated, eventual amputation. No-option CLI means that pharmacotherapy is no longer working, angioplasty, stenting and bypass surgery have failed or not possible and that amputation of limb or limbs maybe the only remaining treatment for these patients. CLBS12 is currently in Phase 2 clinical evaluation in Japan and has received SAKIGAKE designation from the Japan Ministry of Health Labor and Welfare in the treatment of CLI. For those unfamiliar with the nomenclature, SAKIGAKE designation is similar to breakthrough or RMAT designation as awarded by the FDA in United States and promotes research and development in Japan, driving early practical applications for innovative pharmaceutical products, medical devices and regenerative medicines. The CLBS12 as a designated therapy under this system Caladrius enjoys prioritized regulatory consultation at dedicated review system to support the development and review process as well as reduced review time from the typical 12 month down to 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 data generated in our ongoing 35 subject prospective, randomized, controlled open-label, multi-center study in no-option CLI patients in Japan. The study comprises the 35 subjects divided into two cohorts. A 30 subject group with traditional arteriosclerotic CLI and a five subject group with the Buerger's disease a type of CLI often associated with heavy smoking. Those subjects who are randomized for treatment are dosed with CLBS12 through intramuscular injection in addition to receiving standard-of-care pharmacotherapy. Subjects randomized to the control arm received standard-of-care with drugs approved in Japan including anti-platelet agents, anticoagulants, and vasodilators. The choice of which is made by the investigators according to the program. The study allows for the rescue of subject to the control arm by indicating the crossover to treatment if their CLI is deemed to be progressing. The primary objective of this study is to show that CLBS12 can prevent the serious consequences of no-option 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. CLI-free status is a highly clinical -- highly clinically relevant endpoint and encompasses a broader spectrum of improvement in the time to amputation or amputation free survival which are the historical endpoints for CLI studies. Our confidence in this approach to CLI is supported by the substantial clinical data from four prior trials in CLI and claudication conducted in the US and Japan which showed CD34 cell therapy was not only safe but also improved CLI-free status and amputation free survival in those trials. Trial completion remains on target. And in fact, I am pleased to announce that the Buerger’s disease cohort is fully enrolled. We remain confident in our expectations to report top-line data from the complete study in the early part of 2020. As the cost, we project it will require less than $7 million of additional expense to complete this study. Since these costs are part of our current operating budget projections, this study can be considered fully funded to completion. As I have indicated on past call, our strategy is to partner CLBS12 for commercialization in Japan. And to that end, our conversations continue with prospective partners, and we continue to expect to consummate a deal in concert with the completion of the study. Finally, our progress in Japan combined with a high degree of interest and enthusiasm from US and European CLI experts has prompted us to consider the initiation of CLBS12 development in the United States and Europe the commencement of such a program being a function of the identification of the corresponding necessary capital. Moving on to CLBS14-CMD, our proprietary CD34 positive cell therapy for the treatment of coronary microvascular dysfunction. The two CLBS14 programs, CMD and RfA both employe CD34 positive cells isolated, harvested and concentrated in the same way as for CLBS12, but formulated for intracoronary or intramyocardial injection, respectively, specifically for repair and regeneration of cardiovascular tissue. CMD is a plaqueless heart disease involving damage to the inner lining of the tiny arterial blood vessels in the heart. CLBS14-CMD is designed to reduce this damage by exploiting the innate ability of CD34 positive cells to repair small blood vessels and increase microcirculation. ESCaPE-CMD, our Phase 2 clinical study of CLBS14 for the treatment of CMD is enrolling well, and according to plan. As we have previously communicated, most of the costs associated with this trial are covered by a grant from the NIH. And as such, this study should also be considered fully funded through completion. Now, let’s turn to our newest CD34 positive cell therapy program CLBS14-RfA. CLBS14-RfA is intended for the treatment of refractory angina and we’ve worked rapidly since acquiring the exclusive data license to this asset to reactivate the IND and to file for a secure RMAT designation. Regulatory milestones are key to the efficient advancement of the CLBS14-RfA program. We see the addition of CLBS14-RfA to our CD34 portfolio as a core component of our business strategy. The RMAT designation makes cellular therapies eligible for the same actions to expedite development and marketing application review that are available for small molecule drugs that receive breakthrough therapy designation including increased meeting opportunities, early interactions to discuss potential surrogate or intermediate endpoints and the potential to support accelerated approval. Our enthusiasm for this program is based on a series of published Phase 1, 2 and 3 data that include consistency of therapeutic effect with CD34 positive cells to increase exercise tolerance, improved heart functionality and decreased long-term mortality associated with the condition. After receiving the RMAT designation and by the way, we believe we are the only active cardiovascular development programs with such a designation, the next step in the process was to request and conduct a Type B meeting with the FDA. I’m pleased to announce that we recently completed this meeting, the goal of which was to obtain FDA guidance regarding the requirements for registration of this product under the terms of its RMAT designation. Our assessment of the meeting was that it was positive and collaborative and reinforced our expectation that FDA would demonstrate maximum flexibility afforded under the RMAT system regarding the main development steps necessary to bring this minimally manipulated autologous cell therapy product to registration. We will be working with FDA in the coming weeks to finalize our development plan and to formalize the merits of the meeting in any follow on discussion and we look forward to providing further details once these actions are completed. Lastly, let's turn to our landmark Phase 2 study of CLBS03 as the treatment of Type 1 diabetes. Our CLBS03 program using autologous ex-vivo expanded and activated polyclonal T regulatory cells has several key global regulatory designations including FDA Orphan Drug status, EU Advanced Therapeutic and Additional Product Classification and FDA Fast Track designation. As for the latter, we believe that CLBS03 is the first Type 1 diabetes program ever to receive Fast Track distinction. These regulatory designations are key as they provide various exclusivity benefits, tax credits for certain research, a waiver of the new drug application user fee and priority review of regulatory approval submission. As you know, in March, we reported results from the prescribed analysis of the Sanford Project: T‑Rex Study a prospective, randomized placebo-controlled double-blind Phase 2 clinical trial of 110 patients to evaluate the safety and efficacy of CLBS03 as a treatment for recent-onset Type 1 diabetes. The interim analysis was triggered by the completion of the nine months follow of 50% of the targeted total number of subjects in the trial. The analysis was conducted by independent statisticians and showed that CLBS03 continues to be well tolerated and led to the conclusion that the study was non-futile as determined by predefined criteria for therapeutic effect. We remain on track to complete the 12 month follow up on all 110 patients by year-end and to reporting top-line data in early 2019. We expect the trial will provide a tremendous amount of data which we will evaluate vigorously in order to define the next steps in the development of what we will hope will become an important new tool in the treatment of children with recent-onset Type 1 diabetes. We project only about $1 million of remaining expense to complete execution of this trial and since it is also part of our existing plan consider this fully funded to completion. So in closing, we are pleased to share our progress this quarter and to demonstrate continued execution against our stated objectives. Our financial position remains stable, our pipeline programs are progressing. And with the addition of the refractory angina program we have multiple mid and late-stage product candidates under evaluation. We look forward to continued momentum in the coming months and expect to achieve the following milestones: Working with FDA to finalize the development plan for registration for CLBS14-RfA for the treatment of refractory angina; continue enrollment of our Phase 2 clinical trial of CLBS12 for CLI in Japan; continue enrollment in ESCaPE-CMD Phase 2 clinical trial of CLBS14-CMD. And complete the 12 month follow up on all 110 patients in the Phase 2 T-Rex study and announce top-line results. As you can see despite the lack of recent news announcements Caladrius continues to make measurable progress advancing its development programs. Our enthusiasm for our pipeline is reinforced by the fact that we believe to the best of our knowledge that we are the only company with development programs have been awarded respectively the SAKIGAKE and RMAT designations and our dedicated and passionate team remains keenly focused on realizing the potential of these exciting and promising technologies that address large unmet medical need in cardiovascular and autoimmune diseases. And with that overview, operator, we’re ready to take questions.
