Thank you, Phil and good morning everyone. I will dedicate most of my prepared remarks to BL-8040, our unique oncology platform, including some exciting milestones in the coming months, and our recent disclosed entry with this platform into the new-norm quality space. To begin, we are very excited to partner with Merck in the field of cancer immunotherapy. This collaboration allows us not only to enter the exciting field of immuno-oncology through a partnership with a pioneer and leading player, but also to evaluate the potential of our lead drug candidate, BL-8040 in the difficult to treat pancreatic cancer population. Our agreement with Merck, fixed to evaluate the combination of our BL-8040 CXCR4 antagonist with Merck Anti-PD1 immunotherapy KEYTRUDA in a Phase 2 study of the challenging metastatic pancreatic cancer patient population. The planned Phase 2 study, which is jointly designed will be an open label multi-centered single arm trial, designed to evaluate the clinical response, safety and tolerability of the combination of BL-8040 and KEYTRUDA, as well as multiple pharmacodynamic parameters, including the ability to improve infiltration of T-cells into the tumor. We are hopeful that this study will show that the combination of BL-8040 with KEYTRUDA has the potential to expand the benefit of immunotherapy to cancer types that are currently resistant to immuno-oncology treatment, such as pancreatic cancer. Our BL-8040 has been shown in several clinical and pre-clinical trials to be very robust mobilizer of immune cells, and to be effective at inducing direct tumor cell space [ph]. Recent findings also suggest that CXCR4 antagonists such as BL-8040 may be effective in inducing the integration of antitumor T-cells into the tumor micro-environment. Therefore, when combined with KEYTRUDA, we can enable the activation of antitumoral immune T-cells. BL-8040 has the potential to enable T-cells to better reach tumor cells in the fight against pancreatic cancer. Building on this, we continue to evaluate BL-8040’s potential for additional collaboration programs in immuno-oncology, further expanding upon our unique oncology platform. As previously noted, CXCR4 antagonist has been identified as potentially synergistic with immune checkpoint inhibitors. As such, we believe BL-8040’s best in class position make it a great candidate for such collaboration. Turning to BL-8040’s other indications, I will begin with our most advanced program, our ongoing Phase 2 clinical study of BL-8040 for the treatment, relapse or refractory AML, where we remain on track to reporting top line results of the full study by the end of this month. Recent data for the escalating stake of this study presented at the Annual ASH Conference in December of 2015 continue to show highly encouraging results. BL-8040 is a single agent and in combination with cytarabine, was found in one cycle of treatment to be safe and well tolerated as all those have tested, as to and including the highest dose level of 1.5 mg/kg, with no major adverse event. The data showed BL-8040’s strong antileukemic activity, as reflected in the clinical response rate of 38%, consistent demonstration of robust mobilization of cancer cells from the bone marrow, and significant induction of cancer cell death. Following only two days of monotherapy, BL-8040 triggered an average of 44 mobilization of immature AML progenitor cells from the bone marrow to the peripheral blood, thereby making these cells more sensitive to the cytarabine, and improving its efficacy. BL-8040 also showed the direct and significant cytotoxic effects on the immature leukemic progenitor cells in the bone marrow following the two days of monotherapy. Finally, BL-8040 induced leukemic progenitor cells store [ph] differentiation as evidenced by a 58% medium decrease in the number of bone marrow leukemic progenitor cells, along with a threefold increase in differentiated granular size in the bone marrow biopsy conducted on day three of the treatment cycle prior to the cytaribine treatment, as compared to the biopsy performed at baseline. Even the top line results expected later this month confirm the data seen from the dose escalation stage of the trial. We plan to schedule meetings with the regulatory agents in order to decide on our next steps for this indication. Building on this, we are on track in developing BL-8040 for a number of other oncology and immunological indication. This includes our second AML treatment plan. This will examine BL-8040 as part of the second stage treatment, known as consolidation therapy to improve outcome for AML patients who have achieved remissions after the standard initial treatment regimen, known as induction therapy. The consolidation therapy is aimed to eliminating the minimal residual disease left in the bone marrow after induction therapy that can lead to a relapse. In August, we began a large Phase 2b trial, initiating our Phase 2b study in consolidation AML. This is a double blind placebo-controlled study in up to 194 patients. Approximately, 40% of AML patients who achieved first complete remission ends up relapsing within one year, despite the current standard consolidation therapy. And this relapsation has a very poor prognosis, despite further therapy. We are hopeful that our BL-8040 platform will help reduce or eliminate the minimal residual disease due to its dual mechanism of action. Based on positive results from our ongoing Phase 2 relapsed refractory AML clinical study, which showed substantial mobilization of AML cancer cells from the bone marrow to the peripheral blood, as well as induction of apoptosis of AML cells, we believe BL-8040 will be a promising addition to consolidation therapy for AML patients. A third indication for our BL-8040 platform is for the mobilization of stem cell from the bone marrow to the peripheral blood circulation, where they can be harvested for a transplant, supporting bone marrow transplantation and the treatment of hematological indication. In March we reported positive safety and efficacy results from a Phase 1 study, in this indication with the full study finding presented at the EHA conference in June. The study showed that BL-8040 was safe and well-tolerated at a dose of up to 1 mg/kg and induced dramatic mobilization of hematopoietic stem and progenitor cells at all doses tested. The cells collected from the healthy volunteers were also assessed for viability and quality in vitro and in vivo. Importantly, we show that collection of CD34 plus cells was accompanied by mobilization and collection of colony-forming cells as well as T, B and NK cells. These recovered cells were of exceptional quality, and showed excellent engraftment in radiated mice, followed by a rapid reconstitution of normal hematopoiesis. As discussed previously, this data supports the use of BL-8040 as a single-agent, single-injection, one-day regimen for the collection of stem cells. This is a major improvement over currently available procedures, which are lengthier and require multiple administration and multiple time-consuming apheresis sessions. Moreover, we see an improvement in composition of the collective cells, suggesting the potential of the better quality graft that may improve stem cell transplantation outcome. Following a productive meeting with the FDA in October, we announced the filing of regulatory submission required to commence a Phase 2 trial for the use of BL-8040 in stem cell mobilization in December. We are looking forward to starting the Phase 2 study in the next few weeks. Our fourth BL-8040 indication is for a combination treatment, with a standard-of-care immunosuppressants for the two bone marrow failure condition, hMDS and aplastic anemia. One type of treatment for this bone marrow failure condition consists of immunosuppressive therapies. However, a large fraction of patients do not respond to this therapy. Preclinical data suggest this BL-8040 promote stem cell proliferation and differentiation, thereby allowing recovery of hematopoiesis. In November 2015, we announced the start of the Phase 1, 2 trial for this indication, in up to 25 patients, in collaboration with MD Anderson. Treatment for these two bone marrow failure conditions represents a significant unmet medical need, and we hope that BL-8040 as part of a novel treatment regimen will significantly improve bone marrow cellularity and peripheral blood count. We continue to expect partial results from this study by the end of 2016. Finally, we continue on our plan for an additional Phase 2 study in AML patients with FLT3-ITD-mutation. AML patients with a FLT3-ITD-mutation exhibit full response and high relapse rate to chemotherapy, and only transient response rate to FLT3 inhibitors. Preclinical data showed that by inhibiting the CXCR4 receptor, BL-8040 enhanced the effects of FLT3 inhibition in killing FLT3 mutation leukemic cells. The study is aimed to improving the response of FLT3-ITD-mutated AML patients through treatment with a FLT3 inhibitor. We plan to commence this trial, in collaboration with MD Anderson in the second half of 2016. We are focused on moving forward with our aggressive clinical development strategy for BL-8040. The multiple indications provide us with an ability to pursue several high potential unmet medical needs, while reducing the overall development risk for our in novel platform. Further, our entry into immuno-oncology through our collaboration with Merck, not only validates our technology platform, but also extends upon our market opportunities to support and guide us in the expensive development program for BL-8040 across multiple indications, as well as in the development and commercialization affords for additional future oncology projects. We have recently established an Oncology Scientific Advisory Board, consisting of globally recognized clinicians and transitional scientist in oncology. With the knowledge and experience of this impressive group of key opinion leaders, we look forward to realizing the potential of this promising oncology platform, and to reaching several meaningful development milestones during 2016. During 2015, we continue to invest significant effort in our new strategic collaboration with Novartis for the core development of novel clinical stage therapeutics originating from Israel. We continue to jointly screen and evaluate promising therapeutic candidates to be developed under the collaboration, and will provide timely updates on the therapeutic candidates when selected. We also continue to evaluate other potential collaboration arrangement to maximize the value of our current pipeline access, as well as talking to potential partners in order to monetize our non-core program. Before I turn the call back to Phil for the financial overview, I would like to welcome Dr. Merril Gersten, who is joining our Senior Management team. Yesterday we announced Merril's appointment as our new Chief Scientific Officer. Merril brings with her many years of leadership in both academia and the pharma industry in the U.S., and we view her relocation to Israel to join our company as a huge vote of confidence in our pipeline and capabilities. I am confident that she will bring great value to BioLine, and we are all looking forward to begin working with her. And with that, let me now turn back the call to Phil.
