Thanks, Doug. Good afternoon, everyone, and thanks for joining us today. Of course, the most significant development at our company since we talked with you in early March was last Thursday's highly disappointing and surprising vote by the FDA's Oncologic Drugs Advisory Committee or ODAC. This afternoon, we'll provide an update on the ODAC panel outcome and overview of our strategy going forward, including our clinical development program for other indications, and we'll provide a brief update on our EU commercialization. Graham will then review our first quarter financial results and provide an update on the availability and use of resources now and in the coming months. Let's start with the ODAC panel outcome. On May 2, 2013, the Oncologic Drugs Advisory Committee, ODAC, to the U.S. Food and Drug Administration voted that the benefits of treatment with Melblez Kit do not outweigh the risks. It's important to note that the ODAC committee met solely to review certain aspects of the Melblez Kit NDA with the Generation One filter. Equally important is to recall the Delcath NDA contained our Generation Two filter included as a technical change in the chemistry, manufacturing and control module of the NDA as a means to bring the enhanced safety of the Gen Two filter to U.S. patients sooner. As a reminder, our European product is being commercialized with the Gen Two filter. The FDA briefing documents released before the meeting stated that the clinical trial data would be necessary to consider the Generation Two filter for approval, indicating that FDA found our preclinical bridging studies were insufficient alone to approve the marketing of a device containing a new filter. In addition to collecting clinical safety data, the FDA stated in a briefing document that the impact of a filter change on the efficacy of this drug-device combination product is unknown and its efficacy must be established in a randomized clinical trial. Upon learning of the FDA's position regarding the Gen 2 filter in the briefing document, we asked the agency for an urgent meeting prior to the ODAC, which was granted. During this meeting, we discussed our belief that since the filters are downstream of the melphalan delivery to the liver, they do not impact efficacy. We are awaiting the FDA's decision on what additional clinical data will be required to approve Gen 2. Last Thursday, the ODAC panel was presented with the following preamble and associated question. Given the 5.4-month improvement in medium hepatic progression-free survival, the 3-month improvement in median overall progression-free survival and a trend suggesting a detrimental effect on overall survival, along with a 7% incidence of toxic death in the observed risks of serious cardiovascular, hepatic, gastrointestinal and bone marrow toxicities for patients with hepatic dominant metastatic ocular melanoma do the benefits of treatment with the Melblez Kit clinical trial version outweigh the risks. We learned of the FDA's preamble to the final version of the question to the ODAC less than 30 minutes before the ODAC was convened. Despite the preamble, we firmly believe we showed that in a study whose protocol was approved by the FDA, the Melblez Kit has demonstrated a clinically meaningful benefit in both hepatic progression-free survival and progression-free survival. To be specific, the company respectfully disagrees that the "negative trend" associated with the overall survival is a clinically relevant analysis since the overall survival data was confounded by the fact that a majority of the control arm crossed over to receive and benefit from the treatment. We also disagreed with the FDA characterization of the safety data during the conduct of the clinical trials on several important points, and we have communicated these points to the agency. For example, FDA's views related to patient's deaths due to treatment, effectiveness of this serious adverse assent mitigation measures that were instituted in the protocol. And FDA's attribution of patient-related deaths due to the filter used for points that we felt were mischaracterized by the agency in their briefing materials released on Tuesday, April 30. We believe the exploratory one-dimensional perspective associated with the FDA's presentation of these issues didn't provide a comprehensive perspective to the ODAC panel members as well as the public. Let me elaborate on our perspective. The FDA briefing document presented to the ODAC panelists noted that in the pooled safety database, which included both the Phase II and Phase III studies, 7% or 8 patients of the 122 patients, in whom the Melblez Kit treatment was utilized, died as a result of treatment-related adverse reaction. As we presented at ODAC, we did not agree that 3 of 8 patients were due to complications associated with the procedure as the treating physicians continue to be convinced that these patients died of disease progression. We also did not agree with how the FDA further characterized the toxicity profile of the Generation One system as unprecedented. In fact, it should be noted that the 7% treatment-related death during the clinical trial using the Gen One filter is comparable to the currently FDA-approved labeling for the use of inpatients of intravenous melphalan. This labeling has been in place for more than 20 years. The adverse event-related deaths for IV administration of melphalan were 10% prior to the institution of GlaxoSmithKline's clinical trial protocol amendments which lowered this rate to 3%, following the institution of the amendment. This is not unlike the circumstances in our clinical trial. During the course of the clinical trial, we instituted numerous protocol amendments after a patient death. And after implementing these protocol amendments, there were no more deaths associated with the issues addressed by the amendments indicating that the protocol amendments were effective in increasing the safety of the procedure. However, despite the company providing this important data to FDA and ODAC repeatedly, the FDA and ODAC panel did not acknowledge the improvement in safety profile after the Delcath protocol amendments were instituted. A second point for your reference is that FDA has slated -- has stated that the most -- that the post-market safety profile of the Melblez Kit treatment might equal the safety profile observed in clinical testing and that specified training cannot be expected to improve the risk benefit profile beyond that observed in a clinical trial. On this point, we strongly disagree with FDA. In reality, since the institution of protocol amendments in our trials and incorporation of these learnings into our global training program, which include 72 patients treated in our trial as well as a total of 47 commercial patients in Europe and EAP compassionate use in the U.S. There have been no further deaths due to hepatic or gastrointestinal toxicities. Regarding FDA's concern with patient deaths due to hematologic toxicities, it should be noted that prophylactic use of bone marrow growth factor stimulants was rarely used during the conduct of Phase II and current Phase III clinical trial. However, in practice today, these are required. Again, FDA and ODAC panel did not consider the improvement in the safety profile after these measures were instituted, which was surprising and disappointing. In addition to the learnings resulting in protocol amendments and a proposed risk evaluation and mitigation strategies or REMS program, we are further addressing the safety issues related platelet reduction and bone marrow suppression that we saw in our earlier clinical studies through the development of the Gen 2 filter and our subsequent inclusion of it in the NDA. The combination of protocol amendments, proposed REMS and Gen 2 filter, we believe, significantly reduces the side effect profile and have had a big impact on reducing the death rate as is being demonstrated by our European experience. We strongly disagree that the negative trend and overall survival presented by the FDA is clinically irrelevant. We believe that the reason the control arm of the study did very well is because of the majority of patients in it were provided the Melblez treatment. It must be emphasized that because of the crossover of the trial design approved by the FDA, there is no statistically conclusive evidence that can be determined from the overall survival data one way or the other. In summary, we are certainly committed to continuing our interaction with the FDA and doing everything possible to communicate and clarify our strong efficacy data set, the positive impact of our REMS program and the specific patient need for Melblez. While we work with the FDA on review of our application, we continue to move forward with our U.S. expanded access program or EAP. Its focus is to provide eligible patients with access on a compassionate use basis while our NDA is under review by the FDA. As a reminder, our EAP program includes the updated protocol, REMS program and use of the Gen 2 filter. Under the EAP, physicians at select U.S. cancer centers that participate in our clinical trials can use the Melblez Kit in expanded access and compassionate use cases after they obtain Institutional Review Board or IRB approval. These hospitals will provide a base of experienced procedure team trained in the use of the Melblez Kit. Since initiating the EAP in January of this year, 2 patients have been treated with the Melblez in the U.S. under expanded access with one of those patients receiving a second treatment and 5 more patients are scheduled to begin treatment. Before we continue with our corporate update, I'd like to thank the patients, their families and the investigators for their participation in our clinical trials to date. We appreciate your ongoing support, which is critical to our goal of developing Melblez as a new therapeutic option. In addition, I'd like to thank the physician experts who spoke at last week's ODAC to underscore the unmet need in treating patients with unresectable metastatic ocular melanoma in the liver and their passionate belief in the benefits to patients from the Melblez therapy. We appreciate their perspectives and commitment to evaluating new treatment options for this very rare and rapidly fatal disease that remains an essentially untreatable condition with no available standard of care. And importantly, I'd like to acknowledge the hard work of our clinical and regulatory teams in preparing for this ODAC meeting. So now, let me update you on recent progress on other fronts. In April, we announced expanded efforts to increase our efficiencies and reduce our operating cash use this year. Under the program, workforce restructuring actions were expanded, which were combined with earlier workforce reductions, have reduced the company's workforce by 21% this year. Included in the most recent restructuring was the elimination of 2 senior level positions in global sales and business development. As part of the expanded efficacy -- efficiency program, Jennifer Simpson, Ph.D., M.S.N., C.R.N.P. was promoted to the position of Global Head of Business Operations and now heads Global Sales Marketing Regulatory Quality, Clinical Development and Medical Affairs Activity. Dr. Simpson joined Delcath in March 2012 as Executive Vice President, Global Marketing, and has an extensive background in pharmaceutical development and oncology marketing including responsibility for global product development in the oncology sector. Meanwhile, business development efforts are now being led by myself and Graham Miao. To further increase efficiency, we have changed the address our headquarters to our upstate Queensboro, New York facility and are planning to move our New York City operations to a more cost-effective satellite office in New Jersey as soon as we can sublet the New York City facilities. In addition, as a result of last Thursday's ODAC development, we will be able to further reduce our cash utilization through reduced or eliminated consultant use as well as other actions which are under active consideration. Combined, the recent actions will significantly increase our organizational efficiencies, reduce expected cash burn in 2013, and Graham will provide the details in a few minutes on our financial expectations for the combined effects of these streamlining actions. Also during the first quarter, we continue a slow progress on implementing our commercial plan in Europe. To date, 9 of 16 leading European cancer centers in our training and large programs have been trained and activated to provide CHEMOSAT treatments with the most recent addition being the NKI or National Cancer Center in the Netherlands. These activated centers have treated 35 patients with a variety of cancers in the liver, a majority of which have been ocular and cutaneous melanoma liver metastasis, but have also included hepatocellular carcinoma or HCC, cholangiocarcinoma and liver metastasis from breast cancer, gastric cancer, colorectal cancer, neuroendocrine tumors and mucosal melanoma. A critical driver of utilization growth for CHEMOSAT in Europe, and ultimately revenue, will be the expansion of compelling reimbursement mechanisms for the procedure in each of the 7 markets we are targeting. Permanent compelling reimbursement in EU will take some time to secure and in the interim period, we are seeking payment through various avenues including new technology programs. For most countries, we will need the published Phase III trial manuscript reported by investigator initiated trial data before submitting our application. In the interim, we are working closely with experts and our partner hospitals on various interim mechanisms. Now I'd like to review our clinical development program and strategy going forward. During the quarter, the company held productive discussions with the FDA on designs for future clinical trials in new indications. As a result of these discussions and subject to agreement with the FDA, Delcath intends to initiate a pivotal trial in patients with hepatocellular carcinoma, which is known as HCC or primary liver cancer, and expects to enroll patients in this trial by the end of 2013. The primary endpoint for this open label study would be overall survival with no crossover allowed and this study will use the Gen 2 filter. We expect this study to enroll approximately 120 patients and anticipate this study would be about 2.5 to 3 years in length and cost roughly $14 million to $18 million. Cost for the study would be spread over the duration of the study with only about $2 million of the total cost being spent during the first year of the trial. More than 50% of the trial cost would be incurred in the last 12 months or so of the trial. Assuming we get the go-ahead to move forward with this study, the cost impact would be relatively light in 2013. The HCC opportunity clearly provides Delcath and our shareholders with an opportunity for a substantial return if we are successful with the trial versus the cost. HCC is the most common primary cancer of the liver with approximately 750,000 new cases diagnosed worldwide annually. Furthermore, we believe there are well over 100,000 global new cases annually that have an unmet need that would be suitable for CHEMOSAT treatment. Based on this opportunity and unmet medical need, we are making HCC our top clinical development priority because we believe it offers the best value creation pathway for the company. We are also seeking to build clinical experience by sponsoring investigator-initiated trials or IITs with leading EU opinion leaders that have approached us to support new clinical research. We believe these IITs will help grow clinical experience with CHEMOSAT at key centers and will support our effort to obtain compelling reimbursement for CHEMOSAT. With that, I'd like to turn the call over to Graham Miao for a review of our financial results and then we'll take questions. Graham?
