Thanks Joe. Allow me to start our business review with the progress we've made with our CD34 technology. 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. The decrease in blood supply is typically due to disease in the large and small blood vessels that serve the target tissues. There has been an historic focus on strategies to address the problems in large vessels leading to the use of clotbusting drugs, 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. 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 also been shown to induce the development of new blood vessels, thereby preventing tissue death by improving blood flow. We are currently advancing two proprietary CD34 clinical programs namely CLBS12 as a treatment for critical limb ischemia and CLBS14-CMD for the treatment of coronary microvascular dysfunction. Additionally, as we have announced during the quarter, we were delighted to expand our CD34 cell therapy platform with the recent acquisition of a late-stage CD34 cell therapy program as a treatment for refractory angina. To begin advancing this program we are pleased to report that we have reactivated the associated investigation of new drug application with the FDA for the treatment of chronic myocardial ischemia targeting refractory angina. As we disclosed at the time of the transaction, under the terms of the agreement with Shire, we acquired exclusive worldwide rights to the data set and regulatory filings for the CD34 cell therapy program for the treatment of refractory angina in exchange for an undisclosed modest 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 data of CD34 cell therapy as 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. Doug Losordo, our Chief Medical Officer designed and was the principal investigator for the Phase 1 and Phase 2 studies of this therapy which were conducted with the support from Baxter. When Baxter created the spin out Baxalta the program went with it and upon Baxalta's acquisition by Shire the program became deprioritized as it was not core to Shire's orphan and rare disease focus. We are very excited to have secured this promising late stage program given our intimate knowledge of the therapy and because it is complementary to our existing CD34 pipeline. Importantly, this program is supported by data from three randomized placebo-controlled trials. A recent publication in the European Heart Journal combines the data in a pooled analysis from all three studies encompassing over 300 patients and revealed statistically significant improvements in mortality, exercise capacity and chest pain frequency. It is noteworthy that all the data included in the pooled analysis was from studies in which the therapy, dose, and means of administration were identical. The program which we have denoted as CLBS14-RfA represents a large potential 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 annually. With the IND for the program now open in our name, we look forward to discussing with the FDA the most expeditious regulatory path to registration and eventually to bringing this potentially restorative 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 extremity 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 to 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. As I have previously discussed, the ongoing clinical study of CLBS12 and CLI was designed and is being executed according to consultation with the Japanese PMDA on the Phase 2 clinical program and CMC strategy such that it will qualify CLBS12 for consideration of early conditional commercial approval in Japan for this indication under that country's new regenerative medicines laws should the ongoing study yield a successful outcome. In addition, we recently received SAKIGAKE designation from the Japan Ministry of Health, Labor and Welfare for CLBS12 in the treatment of CLI. SAKIGAKE designation is similar to breakthrough therapy designation as awarded by the FDA in the United States. We see this as a significant positive contribution to the development of CLBS12 in that the SAKIGAKE designation system promotes research and development in Japan driving early practical application for innovative pharmaceutical products, medical devices and regenerative medicines. As a designated therapy under the system, CLBS12 will have prioritize consultation, dedicated review system to support the development and review process, as well as a reduced review time from the normal 12 months down to six months. As previously announced, we dosed our first patient in the 35-patient pivotal Phase 2 prospective, randomized, controlled, open label, multicenter study in no-option CLI patients in Japan. Those randomized treatments will be dosed with CLBS12 through intramuscular injection in addition to receiving standard of care pharmacotherapy. Patients randomized to the control arm will receive standard of care with drugs approved in Japan including antiplatelet 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 reverting the patients to a CLI free condition through improved blood flow in the afflicted limb. CLI free status is defined as two consecutive monthly visits in which rest pain is absent and previously non-healing skin ulcers are completely healed as determined by an independent adjudication committee. CLI free is a highly clinically relevant endpoint and encompasses a broader spectrum of improvement in time to amputation or amputation free survival which are the historically used endpoints for CLI studies. Also because this is an open label study, we will be able to monitor patients and evaluate progress in real-time. 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 was not only safe, but also improved CLI free status and amputation free survival in those trials. We expect to incur less than $7 million of additional expense to complete this study and we continue to seek to out license this product for commercialization in Japan and with favorable clinical outcomes to advance this development into the United States. Moving on to our CD34 platform as a treatment for coronary microvascular dysfunction, CLBS14 uses a proprietary and patented formulation of CD34 cells. This treatment is administered via cell infusion into a coronary artery and is designed specifically to enhance the potency of these cells for repair and regeneration of cardiovascular tissues. CMD is a plaque-less heart disease involving damage to the inner lining of the tiny arterial blood vessels in the heart and CLBS14-CMD is designed to reduce the serious adverse consequences caused by damage to the inner walls of the heart's blood vessels through the innate ability of CD34 cells to repair small blood vessels and increase microcirculation. The Phase 2 clinical study of CLBS14 for the treatment of CMD has enrolled its first patient and we expect to announce the treatment of the first patient in the coming week. As we have previously communicated, the majority of the costs associated with this trial are covered by a grant from the National Institutes of Health. Finally, turning to our landmark Phase 2 study of CLBS03 as a potential treatment for type I diabetes. In March we reported results from the prescribed interim analysis in the Sanford Project T-Rex study. As you know, this is 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 I diabetes. The prespecified analysis was triggered by the completion of six months follow-up 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. This means that a positive outcome for therapeutic effect at the end of the study remained a statistical possibility and we have long expected that the analysis of the complete dataset at the end of the study will be necessary to fully understand the impact of CLBS03 on patients. 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 our proprietary method. 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 costs at their two clinical sites in addition to having made $5 million in total equity investments Caladrius since September 2016. As we have also discussed the T Rex study enjoys substantial grant support from other organizations including the California Institute for Regenerative Medicine and the Juvenile Diabetes Research Foundation. 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 which represents the first type 1 diabetes program ever to 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 approval submissions. We look forward to completing the 12-month follow-up on all 110 patients and to reporting topline data in early 2019. We expect the trial will provide a bolus of data that will inform our next steps in the development of what we hope could become an important new tool in the treatment of children with recent onset type 1 diabetes. Moving forward, as Joe mentioned we expect to have less than $3 million of external spending obligations to reach the 12-month readout of data. So in closing, we are encouraged with the progress we have made this quarter which remains focused and supportive of our mission. We look forward to continued momentum in the coming months and we expect to achieve the following milestones: treatment of the first patient in the 20-patient Phase 2 clinical trial of CLBS14-CMD; advance the ongoing enrollment of our Phase 2 clinical trial of CLBS12 for CLI in Japan; gain clarity on the development plan and regulatory path forward for CLBS14-RfA, our new CD34 program for the treatment of refractory angina; complete the-12 month follow-up on all 110 patients in the Phase 2 T-Rex study; pursue additional grants for our CD34 and CLBS03 platforms in multiple indications; and pursue licensing opportunities for CLI in Japan and for other pipeline programs globally. Caladrius continues to advance its clinical programs according to plan and we are pleased that we have accomplished the goals that we had established for the past quarter. We remain committed to judiciously applying our physical resources to support these programs under the leadership of a dedicated and passionate team, one that is focused on realizing the potential of exciting and promising technologies that address large unmet market needs in autoimmune and cardiovascular diseases. And with that overview operator, we're ready to take questions.
