Thank you, Mark and good afternoon to everyone. As Mark just said, this is a very busy and thrilling time for the clinical team here at Galena. On our last call in early March, I went through a detailed analysis of our process to adjudicate events in our PRESENT trial. And as we announced, we achieved our 70th qualifying disease-free survival or DFS event, shortly thereafter. PRESENT stands for the Prevention of Recurrence in Early Stage node-positive breast cancer with low to intermediate HER-2 Expression with NeuVax Treatment. And for your reference, I have again included slide six which depicts our PRESENT study schema and the relevant trial definitions on slide seven. Meeting the 70th qualifying DFS event triggers the pre-planned safety and futility interim analysis and we're currently cleaning the data and preparing an extensive data package for the IDMC review. The analysis is not required by the regulatory agencies, but is performed as a corporate directive to evaluate the futility of the trial midway through our required number of events. The committee will perform the futility analysis and will continue their ongoing safety evaluation of NeuVax for all patients enrolled in the trial. Given the tremendous amount of data and the level of detail required for the IDMC to make their evaluation, we anticipate the committee will provide its recommendation on the interim analysis at the end of second quarter and I have laid out this process on slide eight. To reiterate, the interim analysis is not an efficacy analysis. While the IDMC will have information on each patient's treatment assignment in order to perform the futility analysis, it is very important to note that the study will remain completely blinded to Galena, the investigators, the study staff, patients and all outside parties involved in conducting the trial. As part of preparing the interim analysis and with the support of our recently expanded clinical team, we have been looking at the number of performance metrics from the trial around the 70 events documented to date. It is important to note that the occurrence of the 70th event and its timing was in line with what had been projected previously based on the background rate of events and pre-specified potential benefit of the drug. And while the trial is blinded and we do not have any indication regarding the results for either group, we can look at the overall progress of the trial, as well as the characteristics of those patients who have recurred and those patients who have not. Without knowing the split between the NeuVax and control arms, analysis of the geographical regions and demographics of the patients does not reveal any outlying concern at this time. In addition, the aggregate DFS event rate appears to be tracking with our projections, giving us more confidence that 141st event remains on track to occur in 2018. Since this milestone is two years away, there is still uncertainty around that projection. While our analysis has just begun and more work remains, we're pleased with the overall status of the trial to date. Please now turn to slide nine for the planned study schema for our VADIS trial which stands for Vaccine in women with the DCIS of the breast. While we're hopeful that our phase two trial in women with ductal carcinoma in situ or DCIS, would have initiated last month, the trial preparation remained ongoing at four clinical trial sites, led by the University of Texas and the Anderson Cancer Center Chemo Prevention Consortium. The other three sites are Memorial at Sloan-Kettering Cancer Center, Dana Farber Cancer Institute and Columbia University Medical Center. We're working closely with National Cancer Institute and MD Anderson and expect that trial to initiate this quarter. According to the American Cancer Society, DCIS is the most common type of non-invasive breast cancer, with about 60,000 new cases diagnosed in the U.S. each year. With the phase two VADIS trial, the primary endpoint for the trial is immunogenic, immunologic, evaluating NeuVax in specific cytotoxic T-cells. Importantly, this trial will determine whether long-lasting immunity is induced and evaluate the use of NeuVax in very early stages of breast cancer. Moving now to slide 10, I have included the graphic depiction of all our NeuVax clinical trials. In addition to trials in breast cancer, we also have a phase two trial planned in gastric cancer. As disclosed earlier this year, in collaboration with Dr. Reddy's Laboratories, we presented observational data in patients in India that provided information on the expected screen failure rate in the phase two study and indicated an acceptable potential for enrollment rate. We expect Dr. Reddy's will initiate the trial in the fourth quarter of this year. Please now turn to slide 11, where I have listed the current status of our second immunotherapy program with two assets, GALE-301 or E-39 and the attenuated version of the peptide GALE-302 or E-39 prime. Both assets are peptide vaccines derived from folate binding protein and are targeting the prevention of recurrence in breast, ovarian and endometrial cancers. Last month we presented data from the booster phase of our GALE-301 phase 1-2a clinical trial at the American Association for Cancer Research or AACR, annual meeting. In this trial, patients were randomized to determine an optimal boosting strategy and to see if there was an observable difference between boosting patients with GALE-301 versus GALE-302. The results demonstrated that both boosters were effective, with no measurable difference between them. Importantly, a percentage of patients who received two boosters inoculations and remained disease-free showed a statistically significant improvement in the drug treatment arm versus the control arm regardless of which boosters was used. We're continuing to monitor data from the trial as we evaluate the best path forward for the compounds. Of note, we will be presenting our primary two-year DFS analysis from this trial at the upcoming American Society of Clinical Oncology meeting in June. Switching now to our final asset, GALE-401 on slide 12, over the last few months, we have done a thorough review of the data from our trials, as well as in-depth analysis on the treatment landscape for myeloproliferative neoplasms or MPNs. Breaking out only Essential Thrombocythemia or ET patients, we have laid out the treatment landscape on this slide. Currently, there are two primary treatment options available - [indiscernible] and immediate-release version of Anegrelide. Unfortunately, both come with a safety profile that can lead to premature discontinuation of the drug in a significant number of patients. As you can see in the bottom right box on this slide, there are no attractive therapies for those patients who have failed the current standard of care treatments. Given that GALE-401 is a controlled-release version of Anegrelide, we're evaluating several development paths, including one that could address this unmet medical need. We will be presenting combined safety data from our GALE-401 phase two pilot study and a multiple phase one clinical trials in healthy volunteers. This poster will be presented at the European Hematology Association meeting in June and we'll have a focus on Anegrelide IR in tolerant patients. We will continue to analyze our data and we plan to meet with FDA later this year to discuss the development of the asset. With that, I would now like to hand the call over to John Burns to discuss our financials. Please turn to slide 13.
