Thanks, Joe. Allow me to begin with an update on our landmark U.S. Phase II study of CLBS03 as a treatment for recent Onset Type 1 Diabetes. CLBS03 is a personalized autologous cell therapy consisting of each patient's own regulatory T-cells or T-Rex, which have been expanded in number and functionally enhanced by a proprietary method developed through a collaboration with Dr. Jeffrey Bluestone and renowned researchers at UCSF and for which Caladrius has the exclusive rights to an international portfolio of issued and pending patents. In March of 2016, we initiated The Sanford Project T-Rex Study, which is the first ever prospective randomized, placebo-controlled, double-blind Phase II clinical trial to evaluate the safety and efficacy of T-regulatory cell therapy as represented by CLBS03 in adolescence with recent Onset Type 1 Diabetes. This trial is being conducted in partnership with Sanford Research. Sanford Research is a non-profit research organization that is part of Sanford Health and supports an emerging translational research center focused on finding a cure for Type 1 diabetes. The study is designed to include 111 subjects treated at approximately 15 U.S. based sites. Patients are being randomized to placebo or one of two active arms receiving either 2.5 million or 20 million of their own expanded T-regulatory cells per kilogram of body weight. To address a frequently asked question, we note that the choice of these doses was influenced by the available evidence from previously reported Phase I open-label studies as well as the advice of our Scientific Advisory Board and feedback from FDA. Last fall we successfully completed the 19 patient first cohort and an interim safety review by the independents Data Safety Monitoring Board. Based on these initial observations of safety, we have lowered the age inclusion criteria from 12 years to eight years of age. Enrollment in the second cohort is ongoing and we recently announced the addition of four clinical sites bringing the total of open-sites to 12 including the Joslin Diabetes Center. The study uses standard endpoints for diabetes study including C-peptide measurement and accepted measure of the preservation of beta cell function, insulin use, severe hypoglycemic episodes, and hemoglobin A1c levels. This landmark study is novel and that it also includes extensive immune profiling of CLBS03. To that end, we were pleased that the Juvenile Diabetes Research Foundation recently granted Benaroya Research Institute at Virginia Mason in Seattle, Washington a $620,000 grant to support scientist that BRI and their investigation of the impact of CLBS03 therapy on the immune system of treated patients to better understand the therapies mechanism of action. This grant Benaroya directly offsets costs that Caladrius would have occurred as part of the T-Rex Study. The study also has a pre-specified interim analysis to evaluate early evidence of therapeutic effect. We expect to reach the corresponding enrollment milestone in the coming months with topline data from the interim analysis available on late 2017 or 2018. Data from the 12 months follow-up of all subjects are expected in late 2018 to early 2019. As Joe previously mentioned in conjunction with our private placement from September of 2016, enrollment of the 70 subject will trigger an additional infusion of capital, which is expected around mid-year. We are particularly pleased to have the T-Rex Study supported by a grant of up to $12.2 million from the California Institute for Regenerative Medicine. In addition, Sanford Research made a $5 million equity investment in Caladrius in September of 2016 based on this program and they are providing operating support for the trial at two Sanford clinical sites. As we have previously noted, CLBS03 as a treatment for Type 1 diabetes has received several important 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 to receive this distinction. Our program is supported by published early clinical work conducted by respected leaders in the area of T-regulatory cell science that demonstrated T-regulatory cell therapy to be well tolerated, durable and preserving of beta cell function in children as published in clinical immunology. Supportive two-year follow-up data from this prior study were published in November of 2016 in the peer-reviewed journal of Translational Medicine. Data in conclusions from the latter are informative and will be carefully considered as we contemplate next steps in our development program. We continue to be excited about the potential of T-Rex as a therapeutic platform that has applicability in a number of other immune modulated diseases that represent the multi-billion dollar combined market opportunity worldwide. With the closing of the Hitachi transaction, we can now plan to advance some of the most promising of these opportunities. Among them – and among the new indications being contemplated as a target for our T-cell therapy is neuromyelitis optica or NMO, a rare disease of the central nervous system that affects the optic nerve and the spinal cord. We currently are actively pursuing external sources of funding to apply a pilot study in NMO with groups that support an innovative research to accelerate solutions for the specific or other general orphan diseases. Additionally, Professor Jeff Bluestone at UCSF, the originator of the technology behind CLBS03 in collaboration with Dr. Flavio Vincenti at UCSF is currently evaluating autologous T-Rex as a treatment for sub-clinical rejection following kidney transplant in a study sponsored by the National Institute of Allergy and Infectious Diseases, as well as a study evaluating autologous T-Rex as a treatment for dermal lupus. Caladrius hold intellectual property rights for both of these indications and we look forward to the completion and data readout from these studies as those data will inform our decision to pursue further development in these and/or related indications. Turning now to our CD34 technology. CD34 plus cells have been shown to induce the development of new blood vessels restoring tissue function and improving blood flow. CD34 cells have been investigated in clinical studies encompassing over 700 patients with over 400 receiving CD34 cell therapy exposure. As such there is a myriad of preclinical and human clinical data that supports the assumption that CD34 cell therapy could provide a beneficial therapeutic effect in many cardiovascular and peripheral arterial disease indications. As previously reported, we plan to pursue our CD34 technology as a treatment for critical limb ischemia or CLI, which is a severe obstruction of the arteries that markedly reduces blood flow to the extremities principally the feet and legs. CLI can lead to pain, skin ulcers and sores, and if not successfully addressed even amputation. Our therapy for CLI, CLBS12 is based on previous study of autologous CD34 cell therapy for no option CLI patients in both Japan and the U.S. From those previous studies, researchers found that CD34 cell injection was safe, lead to improvement in CLI free status and improved amputation free survival. We have designed a development program for CLBS12 in Japan based on that country's new regenerative medicine law. Under their newly defined process, we worked with and reached an agreement with the Japanese regulators on a Phase II clinical development plan that is successful should qualify CLBS12 for early conditional commercial approval in Japan for the treatment of CLI. The agreed trial is a 35 patients Phase II prospective, randomized, controlled open-label multicenter study in patients with no options CLI to be conducted in Japan. Those patients randomized to treatment will be dosed with autologous, CGSF mobilized peripheral blood derived CD34 plus cells through interim muscular injection in addition to standard of care. Patients randomized to the control arm will receive standard of care pharmacotherapy alone. The study is expected to cost between $7 million and $8 million over approximately three years with an initial investment of approximately $2.5 million in the first 12 months. We expect to initiate the study in late 2017 or early 2018. With favorable outcomes, we plan to license this application in Japan and continue to engage in discussions with potential partners. Based on the substantial clinical data from four prior trials in critical limb ischemia and claudication, we believe that CD34 cell therapy is not only safe, but can help improve quality of life and potentially treat patients with the serious and life-threatening condition, which we hope to demonstrate through this pivotal study. Beyond CLI, we plan to explore the broader aspects of our CD34 platform therapy, which has the potential to be effective in the treatment of other cardiovascular diseases. We have submitted a Small Business Innovative Research grant application to the NIH for our CD34 cell technology to treat coronary microvascular dysfunction, a heart disease that results in reduced blood flow to the heart muscle resulting in pain and dysfunction. We expect the decision on this funding in the coming months and with this award, our goal will be to initiate a 20 patient Phase II proof-of-concept study before the end of this calendar year. We also continue to explore other sources of collaborative support, such as partnerships or licensing to contribute to any developments at programs for our CD34 technology. In closing, we are newly focused, relatively well funded and poised for progress as a pure-play cell therapy development company with two technology platforms on which to build. We have exciting times ahead and look forward to sharing with you our achievements, which are expected to include enrolling the 70 patients in the Phase II T-Rex Study triggering a capital infusion, reporting topline data in late 2017 or early 2018 from the interim analysis of the Phase II T-Rex Study assessing the early therapeutic effect of CLBS03, initiating the 35 patient Phase II trial in Japan for CLBS12 and no option critical limb ischemia, securing additional grants for our CLBS03 and CD34 platforms and the multiple indications and securing licensing partners with CLI in Japan and for other pipeline programs globally. We are truly focused on executing our clinical program and advancing them rapidly, effectively and efficiently through to important development milestones while continuing to demonstrate a prudent use of our capital. We are confident that Caladrius is transformation to a pure development company will create both near and longer-term value for shareholders and we look forward to updating you on our progress. And now, operator, we're ready to take questions.
