Thank you, Joe. Let's start with the progress we've made with our landmark Phase 2 study of CLBS03 as a potential treatment for type 1 diabetes. We were delighted to complete enrollment of the Sanford Project T-Rex study, a perspective randomized placebo control double-blind Phase 2 clinical trial of 110 patients to evaluate the safety and efficacy of a single administration of CLBS03 as a treatment for recent onset type 1 diabetes. The trial was studying two doses of CLBS03 and the key endpoints are the standard medical and regulatory endpoints for T1D trial and include preservation of C-Peptide which is an accepted measure for pancreatic beta cell function, as well as insulin use, severe hypoglycemic episodes and glucose and hemoglobin A1C levels. The study is 80% powered to detect the 0.2 picomole per milliliter difference in AUC means C-Peptide between the active and placebo arms at 12 month post-treatment. Earlier this month we reported the outcome of the predetermined interim analysis of the T-Rex study which was triggered by 50% of the targeted total number of patients in the trial completing six months of follow-up. The interim analysis was conducted by independent statisticians and found that CLBS03 continues to be well-tolerated. The analysis also led to the conclusion that the study was non-futile as determined by predefined futility criteria for therapeutic effect meaning that a positive outcome for therapeutic effect at the end of the trial remains a statistical possibility. Of course, we have long expected that the analysis of the complete data set at the end of the trial will be necessary to fully understand the impact of CLBS03 on patients and to provide insight into the appropriate parameters to be studied in future trials. As a reminder, CLBS03 is a personalized autologous cell therapy consisting of each patient's own regulatory T cells or T-Reg which have been expanded in number and functionally enhanced by proprietary methodology. Caladrius has exclusive rights to an international portfolio of issued and pending patents for this technology as applied to type 1 diabetes, as well as other indications. The T-Rex study exemplifies our strategy to advance our pipeline programs with collaborative support such as grants, partnerships or licensing. Our partner Sanford Research continues to cover the operational cost at their two clinical sites in addition to having made $5 million in total equity investment in Caladrius since September 2016. We also obtained key grants to offset the cost of the T-Rex study. The California Institute for Regenerative Medicine has committed up to $12.2 million to support the study. In addition, the Juvenile Diabetes Research Foundation granted Benaroya Research Institute at Virginia, Mason and Seattle another organization working with us on the T-Rex study, a $620,000 grant to support Benaroya scientists and their collaborators in their analysis of the impact of CLBS03 on the immune system of treated participants to better understand the therapies mechanism of action. This grant to Benaroya directly offsets costs that we would otherwise have incurred as part of the T-Rex study. We expect the Benaroya data to contribute to understanding the clinical results of the participants and to provide insight into various subsets of patients. In addition to grant support, our CLBS03 program has several key international regulatory designations including FDA orphan drug status, EU, advanced therapeutic medicinal product classification, and FDA fast-track designation the latter representing the first type 1 diabetes program to ever receive fast-track distinction. These regulatory designations are key as they provide certain exclusivity benefits, tax credits for certain research, a waiver of the new drug application user fee and priority review of regulatory submissions for approval. We look forward to completing 12 month follow-up into reporting the topline data on all 110 patients in the T-Rex trial in early 2019. We expect the results will provide a bolus of data that will inform us our next steps in the development of what we hope to become an important new tool in the treatment of children with recent onset type 1 diabetes. Moving forward we expect to have less than $3 million of external spending obligations to complete all activities associated with the T-Rex trial. Turning now to our CD34 technology. Heart attack, congestive heart failure, critical limb ischemia and stroke are often caused by an acute or chronic deficit in the supply of oxygenated blood. The decrease in blood supply is due to disease in the large and small blood vessels that serve the target tissues. There's been a tremendous focus on strategies to address the problems in large vessels leading to the use of clotbusting drugs, angioplasty and stent to treat heart attack and percutaneous and surgical revascularization for chronic ischemic condition. Yet to date, no therapy has been designed to address the defect in the small blood vessels which contributes to the overall impairment of patient with acute and chronic ischemia. One of the body's natural responses to such coronary disease is the recruitment of CD34 cells to ischemic tissues. CD34 cells are preprogrammed to repair damage to the small blood vessels or microcirculation in all tissues. CD34 cells have been shown to induce the development of new blood vessels preventing tissue death by improving blood flow. We are currently advancing two proprietary CD34 programs mainly CLBS12 as a treatment for critical limb ischemia and CLBS14 CMD for the treatment of coronary microvascular dysfunction. Recently, we were delighted to expand our CD34 cell therapy platform with the acquisition of a license from Shire of a late stage CD34 cell therapy program as a treatment for refractory angina CLBS14 RfA. Under the terms of the agreement with Shire, we acquired exclusive worldwide rights to all development information for the CD34 cell therapy program for the treatment of refractory angina in exchange for an undisclosed upfront consideration future milestones, and a royalty on product sales. The comprehensive dataset includes preclinical, as well as Phase 1, Phase 2 and Phase 3 clinical study data that CD34 cell therapy has a treatment for no option refractory angina along with the corresponding regulatory filings. We are especially pleased to have this late stage program as Dr. Douglas Losordo, our Chief Medical Officer while a full-time professor at Northwestern University designed and was the principal investigator for the Phase 1 and Phase 2 studies of this therapy which were conducted under the sponsorship of Baxter. When Baxter created the spin out Baxalta, the program went with it. Upon Baxalta's merger with Shire, the program became deprioritized as it was not core to Shire strategic direction and consequently it became available for our acquisition. Needless to say we are very excited to be moving forward with this promising and complementary late stage program given our intimate knowledge of the therapy. Importantly this program is supported by data from three randomized placebo-controlled trials including data from a partially completed Phase 3 study run under the [offices] of Baxter. It is important to note that Baxter's Phase 3 study was terminated prematurely not for any technical or safety reasons but as a strategic decision that preempted the creation of Baxalta and the eventual sale to Shire. Our recent publication in the European heart Journal combines the data from all three studies in a meta-analysis encompassing over 300 patient and revealed statistically positive improvements in mortality, exercise capacity and chest pain frequency critical elements in measuring treatment efficacy and angina. This program represents a potentially large commercial opportunity for Caladrius as refractory angina afflicts approximately 1 million people in the United States alone with 50,000 to 100,000 new diagnoses each year. We look forward to holding discussions with the FDA in the coming months to determine the most expeditious regulatory path to registration for the CD34 cell therapy program and to bringing this potentially restrictive therapy to patients in need. Let me now turn to CLBS12, our proprietary CD34 technology specifically formulated for intramuscular administration for the treatment of lower extremities ischemia. Critical limb ischemia is a severe obstruction of the arteries that significantly reduces blood flow to the extremities principally the feet and legs. CLI can lead to pain, skin ulcers and dermal sores and if not successfully addressed eventually amputation. No option CLI means that pharmacotherapy is no longer working and that amputation of a limb or limbs is the next step in treatment for these patients. We recently dosed the first patient and a 35 patient Phase 2 perspective randomized controlled open label multicenter study in no option CLI patients in Japan. Those randomized to treatment will be dosed with CLBS12 to intramuscular injection in addition to receiving standard of care pharmacotherapy. Patients randomized to the control arm will receive standard of care pharmacotherapy with drugs approved in Japan including anti-platelet agents, anticoagulants and vasodilators the choice of which will be made by the investigators according to the protocol. The primary objective of this study is to show that CLBS12 can prevent the serious adverse consequences of no option CLI by extending the time of continuous CLI free status to improved blood flow to the afflicted limb. CLI free status is defined as two consecutive monthly visits without disease progression as determined by an independent adjudication committee. This is a highly clinically relevant endpoint and encompasses a broader spectrum of improvement than time to amputation or amputation free survival which are the historically used endpoints in these studies. The endpoint employed in our study has the added benefit of potentially allowing an endpoint to be reached for a given patient in a shorter time frame. This study be conducted following extensive consultation an agreement with the Japanese Pharmaceuticals and Medical Devices Agency or PMDA on a Phase 2 clinical protocol and CMC and quality strategies such that it should qualify CLBS12 for consideration of early conditional commercial approval in Japan for this indication under that country's new regenerative medicine laws. 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 United States and Japan which show CD34 cell therapy is not only safe but also improved CLI free status and amputation free survival. Over the next three years, we expect to invest approximately 9 million to support this program. We continue to seek to out license this product for commercialization in Japan and with favorable outcomes to advance its clinical development in the United States. Review this CLBS12 study in Japan is a potentially rapid entry point to the market and the basis to explore the broader applicability of CD34 therapy which could offer a significant opportunities across multiple underserved cardiovascular indications. Moving on to our CD34 program as a treatment for CMD. CLBS14 uses a proprietary and patented formulation of CD34 cells. This treatment is administered via infusion into a coronary artery and is designed specifically to enhance the potency of the cells for repair and regeneration of cardiovascular tissue. We expect soon to initiate a Phase 2 clinical trial of CLBS14 for the treatment of coronary microvascular dysfunction or CMD which is a plaque with heart disease involving damage to the inner lining of the tiny arterial blood vessels in the heart. CLBS14 CMD is designed to reduce the serious adverse consequences caused by damage to the inner walls of the heart's blood vessels through CD34 cell innate ability to increase microcirculation. The Phase 2 study is a plant interventional open label exploratory trial of infused CLBS14 in approximately 20 patients with CMD. The primary endpoint will be safety and the evaluation of adverse events including serious adverse events as measured by laboratory investigations, physical exams and major adverse cardiac events. Other efficacy endpoints that we plan to assess are change from baseline to six months in coronary flow reserve, endothelial dependent microvascular function, peripheral arterial tonometry measurements, time to angina, total exercise time to ST depression and activity recorded by Fitbit devices during the one-week period. We will also evaluate the change from baseline to three and six months in angina frequency, nitroglycerin use and health-related quality of life. All the defined end points are commonly accepted clinical and regulatory endpoints for study of this type. As previously announced, the study will be conducted with an approximately $2 million SBIR grant from The National Heart Lung and Blood Institute of the National Institutes of Health, which will cover the majority of study costs. This grant underscores acknowledgment by the NIH of the urgent need to develop effective an innovative therapies to treat CMD and support our strategy to advance our clinical pipeline and generate more opportunities within our product portfolio through the use of such nondilutive funding. We are very excited to be advancing our CD34 cell therapy as a medical treatment across these three important cardiovascular indications. Dr. Losordo is a leader in the field giving Caladrius extensive and likely unique experience and expertise with CD34 cell therapy in cardiovascular disease. We look forward to updating you on our progress with these very promise programs in the future. In closing, we continue to be encouraged by the notable progress we’ve made to-date and in the future expect to report clinical data and development program advancement that we believe will provide near and long-term value. Moving forward over the next 12 months, we expect to initiate the 20 patient Phase 2 clinical study of CLBS14 to treat CMD, advance the ongoing enrollment of our Phase 2 clinical trial of CLBS12 for CLI in Japan, gain clarity on the regulatory path forward with our new CD34 program for the treatment of chronic myocardial ischemia targeting refractory angina, complete the 12-month follow-up on all 110 patients in the Phase 2 T-Rex study, pursue additional grants to support application of our technology platform in multiple indications, and pursue licensing opportunities for CLI in Japan and for other pipeline programs globally. Caladrius entered 2018 in a stronger position than ever to advance our strategy and achieve multiple milestones. We have a robust clinical development pipeline advancing with what we believe to be our exciting and promising technologies that address unmet medical needs in autoimmune and cardiovascular disease. We have a strong balance sheet to support these programs and importantly we have an experience, dedicated and passionate team to advance these programs efficiently and effectively as we work to bring innovative treatment option to patients in need. And with that overview operator, we're ready to entertain questions.
