Thanks, Joe. Let me begin by providing an update on our development programs based on our CD34 positive cell therapy platform. Our CD34 positive 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 positive cells induces angiogenesis of the microvasculature or the development of new blood capillaries thereby contributing to the prevention of tissue death by facilitating blood flow to the area of ischemic infill [ph]. We believe that a number of conditions caused by underlying ischemic injury can be improved through the application of our CD34 positive cell technology, including but not limited to critical limb ischemia, coronary microvascular dysfunction, and refractory angina. Our CD34 positive cell technology has spawned the development of CLBS12, our product candidate for critical limb ischemia. CLI is a severe obstruction of the arteries that significantly reduces blood flow to the lower extremities, principally the [indiscernible] 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. No-option CLI means that pharmacotherapy is no longer working, angioplasty, stenting and bypass-surgery have failed or are not possible, and that amputation of a limb or limbs may be the only remaining treatment for these patients. CLBS12 is currently in a Phase 2 clinical study in Japan and has received SAKIGAKE Designation from the Japan Ministry of Health Labor & Welfare for the treatment of CLI. As a reminder, the SAKIGAKE Designation System promotes research and development in Japan driving early practical application for innovative pharmaceutical products, medical devices and regenerative medicine. As a SAKIGAKE designated therapy, CLBS12 is expected to benefit from prioritized regulatory consultation, a dedicated review system to support the development and review process, as well as reduced review time from the typical 12 months down to 6 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 data from our ongoing prospective randomized-controlled open-label multi-center study in no-option CLI patients in Japan. The ongoing study comprises 35 patients divided into two cohorts; a 30-subject group with traditional arteriosclerotic CLI, and a 5-subject group with Burges [ph] disease, a type of CLI often associated with 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 anti-platelet agents, anti-coagulants 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 no-option CLI by reverting the patients to CLI-free condition through improved blood flow in the affected limb. CLI-life 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 an independent adjudication committee. The initial response is observed in the small number of subjects who have reached an endpoint in this open-label study, are consistent with a positive therapeutic effect and safety profile as reported by previously published clinical trials in Japan and in the United States. We are very encouraged by these early results and remain cautiously optimistic recognizing however, that the final outcome of the trial will be dependent on all data from all subjects. As we have previously announced, we expect to record pipeline data from the complete study in the first half of 2020. As to costs, we projected it will require now less than $6 million of additional expense to finish the study. Since these costs are part of our current operating budget projections this study can be considered fully funded to completion. Regarding commercialization, our strategy remains to license CLBS12 for sale in Japan. 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. Finally, previously published work including a study in the United States that showed an improvement in amputation-free survival, and our progress in Japan combined with a high degree of interest and enthusiasm from U.S. and European CLI experts has prompted us to consider the initiation of our CLBS12 developments in the United States and Europe prior to the completion of the study in Japan, depending of course upon the identification of the corresponding capital necessary to fund such a study. Moving onto CLBS14-CMD, our CD34 positive cell therapy program for the treatment of coronary microvascular dysfunction. Like all our CD34 positive cell therapy development candidates, CLBS14-CMD uses a proprietary and patented formulation of CD34 positive cells specifically designed for an injection at/or near the site of ischemic infill [ph] which in the case of CMD is an infusion into the coronary artery. CLBS14-CMD is currently being studied in the escape CMD trial, a 20-patient proof-of-concept Phase 2 clinical trial evaluating CLBS14-CMD as the treatment for coronary microvascular dysfunction, a plaque-less [ph] heart disease involving damage to the interlining of the tiny arterial blood vessels in the heart with no discernible large vessel blockages. CLBS14-CMD is designed to address the symptoms and physiology of coronary microvascular dysfunction by employing the CD34 positive cells innate ability to increase microcirculation. As we have previously communicated, most of the costs of this trial are covered by a grant from the NIH, and as such, this study should also be considered fully funded through completion. The early results observed in the escape CMD open-label study from the small number of subjects who have reached to 6 month at follow-up visit support our expectations of a positive therapeutic effect and acceptable safety profile for CLBS14-CMD in this indication. And while the final outcome of the trial will be dependent on the 6 months data from all subjects, these early observations of increased coronary flow reserve with a corresponding decreased angina systems in treated patients are encouraging. Top line data from the completed study are expected to be available by the end of 2019 or early 2020. And now turning to our most clinically advanced CD34 positive cell therapy program, CLBS14-NORDA. CLBS14-NORDA is believed to address no-option refractory disabling angina by stimulating the growth of new microvasculature in an oxygen-deprived heart. Our enthusiasm for this program is based on a series of published Phase 1, 2 and 3 study results that indicate a consistency of therapeutic effect with CD34 positive cells to increase exercised tolerance, improve heart function and decrease long-term mortality associated with the condition. Since acquiring the rights to the data and regulatory filings for CLBS14-NORDA for the treatment of refractory angina, we have successfully reactivated the IND with the FDA with Caladrius as the sponsor and received regenerative medicine advanced therapy, i.e. RMAT designation from the FDA. The RMAT designation affords us the opportunity to work with FDA to advance more rapidly and efficiently the development of this therapeutic candidate in an indication that currently has high morbidity and no effective treatment options. We are in the process with FDA of finalizing the protocol design of a single Phase 3 trial for the registration of CLBS14-NORDA, and are targeting the initiation of that trial in the full 2019. Lastly, I'll simply reiterate our recent announcement regarding the top line results of our landmark Phase 2a study of CLBS03. CLBS03 has been development for several years as a possible treatment for Type 1 Diabetes and is based upon our proprietary T-Regulatory cell platform technology for immuno-modulation. CLBS03 was granted fast-track in orphan drug designations from the FDA for this proposed indication, and was granted Advanced Therapeutic Medicinal Product Classification from the European Medicines Agency. This program is based on the use of T-Regulatory cells or T-Rex to treat diseases caused by imbalances in an individual immune system. This novel approach seeks to restore immune balance by enhancing T-Rex number and function. And when T-Rex function properly, only harmful foreign materials are attacked by effector T-cells. In autoimmune disease, however, it is thought that deficient T-Rex activity and numbers permit the effector T-cells to attack the body's own beneficial cells, and in the case of Type 1 Diabetes, the beta cells in the pancreas are attacked thereby reducing or eliminating overtime the patient's ability to produce insulin. In 2016 we commenced patient enrollment in the first of two cohorts in the Sanford Project T-Rex Study, a Phase 2a prospective randomized placebo-controlled double-blind clinical trial to evaluate the safety and efficacy of CLBS03 in adolescents with recent onset Type 1 Diabetes, i.e. the T-Rex Study. On February 13, 2019, we announced top line results indicating that the therapy was well tolerated but that the studies primary endpoint of preservation of C-peptide at the group level had not yet been achieved. We anticipate that overtime a comprehensive analysis of all data from the trial including individual patient level data will be conducted culminating with the results of the 2-year follow-up data for all subjects. Any decisions regarding the next steps in development of CLBS03 are naturally dependent on those results. As we await the completion of the comprehensive analysis of study data, we again express our sincere gratitude to the patients, families and investigators involved in the T-Rex Study for their participation and commitment. So in closing, we are very pleased with the corporate and development achievements we made throughout 2018. We believe these accomplishments form the foundation from which we expect to attain a number of key milestones in 2019 and beyond. These milestones include the initiation of a Phase 3 clinical trial for CLBS14-NORDA in the United States upon finalization of a protocol design with FDA. Completion of enrollment of our Phase 2 clinical trial of CLBS12 for CLI in Japan and announcement of top line data results. And completion of enrollment in the escape CMD Phase 2 clinical study of CLBS14-CMD in the United States and announcement of top line data results. Caladrius entered 2019 on strong operational and financial footing, and we expect to build on the momentum throughout the balance of the year. Our experienced, dedicated and passionate 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 restore human health. And with that overview, operator, we are ready to take questions.
