Thank you, Kim, and good morning everyone. Joining me today is Jeffrey Church, Our Executive Vice President and Chief Financial Officer, who will provide a review of Celsion’s recent financial results in a few minutes. Also on the call for the question-and-answer portion is Dr. Nicholas Borys, our Chief Medical Officer. As always, it's a pleasure to speak with you.But it's hard to believe once again, I'm speaking with many of you who are confined to home is this COVID epidemic continues to impact our daily lives. I hope that all of you have remained safe and healthy and will continue to do so. We've had a great deal of exciting news during the first quarter in recent weeks from both of our lead programs, first and critically important, our ThermoDox Phase III OPTIMA Study for the treatment of newly diagnosed hepatocellular carcinoma or primary liver cancer reached the prescribed number of events in April for our second pre-planned in term efficacy analysis and I will discuss this more in a minute.Equally important however is the wave of ongoing positive news that we reported regarding the development of GEN-1, our immunotherapeutic currently being evaluated in the OVATION 2 study, a Phase I/II to trial in newly diagnosed advanced ovarian cancer patients. In addition to our steady drumbeat of positive clinical research dose, as I've outlined in my letter to shareholders last month, after seeing the extraordinary volatility and signals of economic retrenchment, we have smartly taken steps in the most shareholder-friendly ways to strengthen our financial position.Jeff will talk about this more, but our goal as you know is to further assure that our cash runway extends into the second quarter of 2021, during which we expect to report several key milestone events. I'd also like to report, as I have in the past and said many times Celsion's fundamentals continue to be strong. Our advanced clinical programs are directed to large patient populations with unmet medical needs, with poor prognosis. We have sufficient cash to see the Company through several important value-creating milestones, and execution of our clinical development programs, as I said before, have been with the utmost care and with a strategic focus, all supported with extraordinarily talented and loyal staff.So, it's appropriate then to recognize our employees and include our partners, the research physicians and their staffs and our consultants and professional members of the CROs who are engaged in our studies and other development projects. We recognize them for their grace under pressure during the current pandemic and to let them know that their dedication is very much appreciated, not only by this management team, by the medical community and the patients, who ultimately will benefit from our research programs.I'd like to start by discussing our Phase III OPTIMA Study of ThermoDox or HEAT sensitive liposomal formulation of doxorubicin for the treatment of primary liver cancer. We recently announced the study reached 158 events or deaths triggering our second preplanned interim efficacy analysis by the studies, independent Data Monitoring Committee or DMC. At the time of date of cutoff, we actually had 160 deaths that will be reviewed by the DMC. The meeting of the committee members has been scheduled. Data lock has been implemented. Data QC is being conducted and reports are being prepared. We expect to report the interim results following the DMC meeting early in July.Now, as I said before, we believe that, there's a very good potential for success at this analysis, but of course it's not a short, the Company remains blinded. I'd like to give you some insight into the support for our belief that the study is on track for success. Supporting our belief is our comparison of the threshold for success to the data from the data that OPTIMA Study was based on. The P-value and the hazard ratio for OPTIMA success and 158 events are 0.022 and 0.7 respectively. P-value for success is 0.022. The hazard ratio for success is 0.70 respectively.This compares favorably to the P-value and hazard ratio observed for the 285 patients in the prospective, I repeat, prospective subgroup from our earlier Phase 3 HEAT Study, upon which the OPTIMA Study protocol was based. This prospective subgroup from the HEAT Study demonstrated a two year overall survival advantage for patients treated with a single dose of ThermoDox, when compared to the studies controller and a remarkable median time to death of more than seven and a half years. Why do I say remarkable? At the time the HEAT Study was conducted, median time to death was expected to be only 36 months.The subgroup hypothesis and trial design were confirmed by the National Institutes of Health. At the institute's request, not ours, they asked us for the data to review independently, in their independent review of the HEAT studies, 432 patients with single lesions that's over 60% of the study population. They concluded that a thesis supporting the optimal trial is valid. Taking all of this into account throughout kind of summarize by saying the bar for success at this second analysis is lower than what we’ve seen in the prospective HEAT studies subgroup, a subgroup again, that was validated by the NIH using a different slice of the data.So, we look forward to receiving the DMC's recommendation on the potential for a positive outcome regardless, however, I believe the OPTIMA Study is ultimately well positioned for success, if a third and final analysis is necessary will be based on 197 patient deaths. At that point, the bar for success will be even lower. The P-value and the hazard ratio required at the final analysis, if it's necessary, are 0.043 and 0.75, respectively, which is far lower than the values observed in the prospective HEAT Study subgroup. If it's necessary, we anticipate this final analysis will occur in the first quarter of 2021.I will again remind you also that our confidence of any underlying hypothesis supporting the OPTIMA Study is not hours long. Thought leaders from the medical community and distinguished scientists have weighed in. Conclusions from peer reviewed manuscripts including published preclinical data supporting the OPTIMA Study, the public HEAT Study manuscript validating the subgroup results, and again, the NIH is published analysis in support of the HEAT studies hypothesis all pointing in the same direction.And we're further encouraged we look at the trends comparing the studies current combined timeline for disease progression. PFS and the patient death rates, both of which are tracking in line almost too perfectly with the prospective HEAT Study subgroup, I’ve been asked, has the COVID virus pandemic affected our OPTIMA Study? I'll point out that our plans for the DMC meeting in July includes the impact of COVID-19 which accounted for a few extra weeks to ensure that all of the data input is clean and current before presenting to DMC.We discussed this during the last conference call. We took a few extra weeks just to make sure that all the monitoring, the appropriate monitoring was complete largely due to the some of the restrictions from for our monitors being able to visit the hospitals in some of the areas of the world where restrictions were -- monitory restrictions were in place. Otherwise, other than this very short delay for the DMC meeting, the coronavirus has virtually had no impact on the conduct of the study or patient follow-up despite many of the clinical trial sites being in China and other countries where the virus has had an impact.I want to go on to GEN-1. While we prepare for the TMC review, we continue advanced the development of our immunotherapy candidate GEN-1, now we evaluated as I said in the OVATION 2 Study, a randomized Phase I/II trial and newly diagnosed advanced stage ovarian cancer patients. In this study, GEN-1 is being combined with a standard of care, neoadjuvant chemotherapy compared to the control arm of neoadjuvant chemotherapy alone. There is a Phase I portion as we've talked about. It's a running at 100 milligrams per meter squared, 30% higher than the dose that concluded the first Phase I study of GEN-1.This Phase I study included 12 patients, 6 on the treatment arm, 6 on the control arm, those 6 patients have been treated and enrolled and have been evaluated. We are now looking forward to Phase II and enrolling up to 118 additional patients in the Phase II program for a total of 130 patients in this trial. As for background for those of you who are new to Celsion, GEN-1 is engineered using our proprietary TheraPlas platform technology. TheraPlas, as the name implies is a non-viral nanoparticle gene delivery system that provides a means to transfect cells with plasmids coded for proteins of therapeutic value.GEN-1 incorporates the gene sequence for interleukin 12 or IL-12. It is administered local regionally into a body cavity such as a peritoneal for ovarian cancer treatment. Following administration, cell transfection has accomplished among millions and millions of cells resulting in persistent, durable, local secretion of up to a week, secretion of up to a week of the IL-12 protein. IL-12 is well known as one of the master switches of the body's immune system, recruits the immune system, the entirety of the immune system and has proven to be an effective means to fight malignancies.The beauty of this technology and I said it over and over again is that, the durability of the response of a week recruiting the immune system and the ability of GEN-1 to be repeatedly administered in our Phase II Study will be administered in 17 weekly cycles, goal of which is to ensure that the immune system is sufficiently active to treat cancer cells that may have escaped either surgery or neoadjuvant chemotherapy.Initial results suggest that, this mechanism is having an effect. I'll talk about that more. As I mentioned at the beginning of the call, we've had a steady stream of encouraging news regarding GEN-1 during the quarter. In February, the DSMB declared a 100 milligram per meter dose to be safe and recommended continued follow-up is required per protocol to ensure that, the maximum 17 doses are safe, particularly following interval debulking surgery, which is part of the treatment protocol for these patients.Final and next evaluation of the 100 milligram per meter dose will be in approximately two weeks. We fully expect a recommendation from the DSMB to continue Phase II at 100 milligrams per meter squared, partly due to a very positive safety profile of our GEN-1 therapy. In March, and another news-related to GEN-1 in ovarian cancer was granted Orphan Drug status by the European Medicines Agency. You may know this is quite an accomplishment, so it's not just granted, it requires both a sponsor to supply incidents data from a variety of sources as well as some demonstration of efficacy of our drug in early phase trials.The value of this designation is manifold. It provides for 10 years of market exclusivity following approval. It provides us with EMA’s protocol assistance. It gives us access to a centralized procedure. This is very important following immediate -- allowing for immediate marketing authorization in all of the member states of the EU. It would become eligible for a reduction of regulatory and marketing authorization fees. I want to note also that the GEN-1 previously received orphan designation from the FDA, providing among other things a 7-year regulatory exclusivity from the time of approval, all very -- both very positive for GEN-1.In mid-March, we reported that pulling Phase I data from our prior OVATION-1 study with a 12 patients treated OVATION-2, the Phase I portion of OVATION-2. The Company now is highly encouraging dose dependent tumor response and surgical scores, surgical scores being a predictor of an improvement in overall survival. In late-March, highly encouraging PFS progression free survival findings were reported comparing OVATION-1 patients versus a statistically validated synthetic control arm. The synthetic control arm is provided to us by Medidata. Many of you may know that name. They're a world leader in clinical data management.This is a cutting edge approach that's being developed by Medidata to a clinical trial strategy. The goal of which is to provide a replacement for some or all of the control arm patients in a clinical trial. While the hazard ratio that we saw when we compare our patients to the synthetic control arm in this Phase I study in a 15 patients, the hazard ratio was 0.53 almost a doubling, over a doubling of I'm sorry, of median time to progression while when we compared our patients treated with GEN-1 for the synthetic control arm. As I said before, this is quite remarkable, but it doesn't stand alone. It's supportive with impressive published by translational and clinical data from our prior Phase I experiences.So, we weren't surprised or surprised by the magnitude. We weren't surprised that PFS improved, largely due to the mechanism of action that we are seeing in the translational data and all other clinical outcomes from our Phase I experiences. So, we're very excited about these data. I hope you hear that in my voice and we believe that they want strong consideration for strategies to accelerate the clinical development program for GEN-1 and newly diagnosed with ovarian cancer, advanced ovarian cancer patients by the FDA and we’ve discussed for a strategies with them in the past. We are not submitting a brief based on these data -- we have submitted a brief based on this data to the FDA outlining the results and our point of view. I'm encouraged and I'm expecting to post you on the agency's response in the next 30 to 60 days.All in all, we're building the foundation for what we believe to be a lucrative asset worldwide should GEN -1 development work, continuous plan and show the efficacy that is being noted in early work. Well, I do need to point out, as I suggested in an earlier call, there is a modest delay and I'd say modest. During our year end call in March, I pointed out that we did not anticipate any significant impact on our GEN-1 program due to the COVID issue. And as I pointed out, that delays, if any, would not amount to more than a few months. Well, after assessing the evolving situation over the past six weeks or so, we've decided to delay the Phase II portion of the OVATION 2 Study by approximately 3 to 5 months.This delay is due to a decision made by the Company largely made by me out of an abundance of caution. It's because we assure the quality of our investigational product to ensure that the product meets our finished product, meets our specifications and our quality requirements. We have always mandated that's true for ThermoDox as well as GEN-1, we've always mandated that our formulation scientists be present in the manufacturing facility during the manufacturing runs of our product. But with this COVID-19-related travel restrictions and with some strict limitations on visitors to their manufacturing facilities by our contract manufacturing organizations, we were unable to have these technical resources onsite in the factories at this time.So, I've decided to postpone manufacturing until we can be present, that delay may be up to September. It's incumbent upon us to make sure that, we have investigational product available to treat our patients. So, we have decided again out of abundance of caution not to initiate Phase II until manufacturing has resumed in the next few months. As I said, this is cautionary and frankly, it's just good practice in the overall scheme, this few months are not material success for our program. But a -- production of GEN-1 would be material to the success. So, it caused an enormous delay.Meanwhile, we're looking for ways to accelerate patient enrollment. So, this few months delay may have only a minimal impact if any on study completion. So to be precise, our guidance now is that, the Phase II portion of OVATION 2 will commence in the fourth quarter, early in the fourth quarter, where we had previously announced guidance that the second, the Phase II portion will commence in the second half of 2020.I also want to elaborate on what was included in our press release. The return of the $630,000 SBA loan made to us under the payroll protection program of the CARES Act. We believe our loan application was more than justified and consistent with our understanding of the intent of Congress and the administration very clear to us. But after some consideration and consultation with counsel, it become increasingly clear to me that, the guidance for loan qualification continues to evolve as late as yesterday. I think we've gotten some recent guidance not only from the SBA but also from the SEC.So rather than subject, the Company to decision uncertainty after the fact is decided to return the funds, then the deadline provided by the U.S. Treasury Department that occurred yesterday. Now to compensate, we've taken steps to offset this modest financial impact through some payroll adjustments and temporary reductions, and we're taking other actions to improve cash flow. My colleague here, Mr. Church for example has renegotiated the deferral -- negotiated deferral of a principal payment under our Horizon Venture Loan that once the documents are signed here may more than offset, more than offset the $630,000 that we've returned to the government.Our goal is always, as I've repeated many times just ensure that we have cash runway through the many major milestones that, we expect to achieve before the end of the quarter, second quarter of 2021. And we will -- I commit to you do everything in our power to ensure that that happens. So I'll conclude with a few points here on what I've been saying for some time now your company's fundamentals are sound. And as each day turns we grow stronger, our immediate meetings with various regulatory agencies which have been regular have resulted in no significant issues and in fact have been quite encouraging, as show in our recent orphan drug designation for GEN-1 from EMA.Our manufacturing strategy can be characterized as solid. Our focus on redundancy during this pandemic has served us well, as I pointed out in our last year end discussion. Our product costs, our cost of goods is enviable with the promise of high gross margins, no matter the market or the region. You know for example that ThermoDox addresses HCC, a malady that's highly concentrated in China in Southeast Asia, poor countries, frankly, where low cost of goods, assures us good gross margins, but more importantly, the ability to provide this life saving potentially lifesaving drug to HCC patients worldwide.As Jeff will point out, our spending and cash management have been tight and focused in each of our two investigational products. I'll conclude with this point I've said it over again. Each of our two investigational products, have blockbuster market potential by anyone's standard or measure. The OPTIMA Study is on the cost of generating important and potentially transformational results. We have every confidence in our trials, our investigators and our collaborators, our product technologies, and most importantly, our employees. Despite the COVID-19 turmoil, Celsion looks forward with laser focus to the balance of 2020. A year that we have every reason to believe will be transformational for patients, the medical community and our investors.Now these comments, I'd like to turn the call over to Jeff. Jeff?
