Thank you, Jeff. Good morning, everyone and thank you for joining today’s call. With me are Dr. Nicholas Borys, Celsion’s Chief Medical Officer and Jeffrey Church, our Chief Financial Officer from whom you have just heard. As always, we are very pleased to have the opportunity to update you on our progress and to answer your questions. Now, let me start this call by reminding you that our 2018 Annual Shareholder Meeting will be held on Tuesday of next week at the Westin Hotel in Princeton, New Jersey, I would like to encourage all shareholders of record to consider joining us for the meeting if you can. If you have pleasure to see you, because as always, it’s great to meet with you in person whenever possible and we are on a great deal. Since we just held our year end call a little over a month ago, today’s conference call will be relatively brief and perhaps redundant in a few closes, but there is much worth repeating. So, let me start this call, where we ended our call in March and to remind you, I made four key points for investors to consider as Celsion entered this year 2018. Number one, we have an operationally tight focus with both conserves cash and more importantly ensures the timely events when of our two very promising clinical trials, the OPTIMA study, our pivotal Phase 3 trial of ThermoDox, a newly diagnosed primary liver cancer reminds you that’s the largest unmet medical need remaining in oncology today in the OVATION II study, a Phase 1/2 trial of our gene mediated immunotherapy GEN-1 in newly diagnosed advanced ovarian cancer patients. And number two, Celsion started the year with a strong balance sheet over 20 months worth of cash and runway sufficient to achieve a number of very important development objectives, including full enrollment and rate of the data from the first interim analysis of the OPTIMA study and the initiation of OVATION II in top line results from the first cohort of up to 12 patients and that will be 6 in the treatment arm and 6 in the control arm in the study by the end of the year. The third point to consider, if you are thinking about Celsion is our trials continue to advance. Investors should have expectation in steady news flow of key developments over the course of 2018 and into 2019. And now before we will be pursuing non-dilutive means to add to our financial resources, including the sale of net operating losses or NOLs, which could add two to three quarters worth of operating run-rate taking the company well into 2020, the point at which the results from our Phase 3 OPTIMA study should be well behind us. Now, Jeff will speak to this in more detail later in the call. We are very pleased with 2018 and operationally tight focus ensuring timely achievement of clinical development goals and efficient cash utilization, a strong balance sheet providing runway to critical inflation points, including full enrollment of the Phase 3 study in the first interim efficacy analysis, a commitment to steady news flow of key developments and a financing strategy that focuses on shareholder value. That’s our client. Now, I would like to review our technology in the clinical studies beginning with our lead investigation on drug, ThermoDox. ThermoDox, as you know, as the name implies is a heat sensitive liposomal formulation of doxorubicin, being evaluated in combination with radiofrequency ablation, administered for a minimum of 45 minutes in a patient population with tumors greater than 3 centimeters less than 7 centimeters, in a Phase 3 study called the OPTIMA study. Now, this is a global trial being conducted in 14 countries across 17 time zones in all markets for hepatocellular carcinoma, primary liver cancer or HCC as we will call it is a significant product. The 550 patient study is quality to the type of 33% improvement in overall survival. The thesis for our protocol is based on our understanding of the application of RFA for 3 centimeter and greater lesions and the survival impact on RFA is just correctly up to minimum of 45 minutes when combined with ThermoDox. A 285-patient subgroup that represents 42% of the intent to treat population from the prior HEAT study, a group that was followed for over 2.5 years. Median time to death in the treatment arm was never reached after 80 months, that’s more than 6.5 years median survival and over 2 years better than the control group. Our investigators are excited about the results that concluded that the single dose of ThermoDox with properly administered RFA has the potential to be cured. We have been presenting this narrative at multiple medical conferences over the last number of years. In addition to our survival observations, the thesis for combining ThermoDox with RFA standardized for a minimum of 45 minutes has been tested in preclinical and computational models. Our conclusion of combining ThermoDox with properly administered RFA has the potential for greater than 2 year survival benefit is not Celsion’s alone. It has been validated by the medical research community in multiple publications and journals. Manuscripts supporting the basis for the OPTIMA study cover virtually every respect of our analyses and have been published in peer reviewed journals, including our clinical cancer research in 2017 plus 1 in 2015 in the Journal of Hyperthermia in 2010. These analysis support the premise that the longer the HEAT target lesion and surrounding tissue was heated, the greater the doxorubicin concentration, bidding to rehypothesize and more effective tumor treatment and potential for significant improvement in overall survival. In April, this past April, the Independent Data Monitoring Committee or DMC met for schedule unblended review of the data from the study was reviewed among other things, includes ensuring each sites compliance with the specified minimum RFA heating time. The DMC unanimously recommended that the OPTIMA study continued according to its protocol to its data readout. Recommendation that was based on their assessment of safety and data integrity of the first 75% of patients randomized in the trial through early February. In addition and very importantly, we learned that the blinded progression-free survival in the intent to treat population for this study was so far consistent with the PFS in the subgroup population that showed benefit in the HEAT study and we can see that again. We learned that the blinded progression-free survival in the intent to treat population in the OPTIMA study is so far consistent with the PSS in the subgroup patient population that showed benefit in the HEAT study. I want to emphasize the study is blinded and remains blind and no definitive conclusion can be drawn to point at ThermoDox’s performance specifically. We nevertheless view this finding as encouraging and continue to believe that ThermoDox with properly administered RFA will be found in the acceptance in treating HCC. Now, I want to repeat some comments from the last call, last March call for those who are new to Celsion. In 2016, at the request of Director of Interventional Oncology, we provided the National Institutes of Health with 3 terabytes of HEAT study data from which they conducted an independent analysis of the intent to treat population of 437 single lesion patients from the HEAT study, now that’s in a different population and then I just discussed where we saw an improvement in overall survival in the treatment arm equal to greater than 80 months, median time to death greater than 80 months. So this population, single lesion patients all patients with single lesions in the study were evaluated. While the study looked too virtually identical with evaluation of study two virtually identical cohorts, it’s RFA with ThermoDox and RFA alone, NIH concluded was that when combined with ThermoDox, longer RFA heating times resulted in a statistically significant improvement in overall survival. This is not true of RFA alone. These findings were presented at the RSNA conference in December 2016, that’s the Radiological Society of North America Conference, one of the largest medical conferences conducted annually in the world. More recently in February of 2018, an abstract discussing the company’s Phase 3 HEAT study, evaluating ThermoDox in combination with RFA was 1 of 6 selected for presentation by the HEAT study manuscript by leading author Dr. Won Young Tak and is part of the luxury of the Presidential selection of the Korean Liver Cancer Association’s 12th Annual Scientific Meeting in Seoul, South Korea. So when you look at all of this, the NIH’s interest on investigators in the HEAT study interest in bringing the HEAT study data and the results are showing an improvement in overall survival to their colleagues at multiple medical conferences, Dr. Tak’s presentation. If you look at all of this, you can’t help but conclude as I said before, this is one rare time, where clearly the medical community gets it before Wall Street does. I will also note that the 14 regulatory authorities from across the globe in all major HCC markets, including Europe, North America and Asia that reviewed and approved the OPTIMA study protocol. Our regulatory strategy is based on these interactions. We have designed the OPTIMA study to enroll sufficient number of patients from each country to support registration filings and market launch in the U.S., Canada, Europe, China, South Korea, Taiwan, the Philippines, Thailand, Malaysia and Vietnam. In the U.S., ThermoDox has received fast-track designation and provides for among other things priority review. ThermoDox has also been granted orphan drug designation for primary liver cancer both in United States and Europe, which extends market exclusivity for 7 and 10 years respectively in these major revenue markets. Additionally, the CFDA, that’s the China Food and Drug Administration informed Celsion, that’s Dr. Borys and me, so if the ongoing Phase 3 OPTIMA study is successful, the trial could serve as a basis data from the trial, can serve as a basis for direct regulatory filing in China without the need to file for prior approval in the U.S. or Europe, which is currently required for many foreign company applications. While this departure from conduction would allow Celsion to accelerate its financial and regulatory filing in China and if approved, but provide for significantly earlier launch in China than originally anticipated. China represents of course perhaps the most significant market opportunity for ThermoDox globally is approximately 50% of deal with 850,000 newly diagnosed HCC patients originating in China each year. Now, with regard to the trial itself on the execution side, we have engaged internationally recognized world class contract research organizations and data management teams to ensure Good Clinical Practice, ICH compliance, protocol adherence and high quality data analytics. We also have a proven and highly reliable supply chain with 3 redundant contract manufacturing organizations were registered and capable of producing ThermoDox in all regions of the world supporting high gross margins regardless of the market. Now, I want to turn to GEN-1. As I discussed last month, GEN-1 developed on our TheraPlas technology platform is a gene-mediated immunotherapy, which recruits the body’s immune system to fight malignancy. GEN-1’s active agent is a DNA plasmid coded for the potent anticancer cytokine, IL-12, or interleukin-12. The IL-12 plasmid is incorporated into our proprietary synthetic nanoparticle delivery system called TheraPlas. When administered locally into a body cavity like the bladder or the peritoneum or even a cavity created by surgical removal of a tumor mass, these nanoparticles invade or transvect the surrounding cells and take over the metabolic machinery, turning each cell into a little biopharmacy for the local sustained production of interleukin-12. The first indication we are studying for GEN-1 is as you know is ovarian cancer. For patients newly diagnosed with this cancer, there is less than a 45% chance of surviving 5 years. One of the major reasons for this is that the diagnosis is made when the patients have advanced disease particularly in stages 3 and 4, when the cancer is spread throughout the pelvic region. In previous clinical trials in patient populations with recurrent disease, GEN-1 has been used both as a monotherapy and in combination with standard chemotherapy and is showing promising results. Most importantly, however, GEN-1 demonstrated clear signs of activity in clinical benefit in newly diagnosed ovarian cancer patients in our Phase 1b dosing escalation trial, the OVATION I study. The OVATION I study evaluated GEN-1 plus neoadjuvant chemotherapy followed by interval of debulking surgery in newly diagnosed advanced ovarian cancer patients. The goal of neoadjuvant chemotherapy is to improve surgical outcome by shrinking the tumor mass and drying up the accompanying fluids [indiscernible]. In the study, we added 8 weekly cycles of GEN-1 to this chemotherapy regimen then followed by surgery. Our findings from this study include the following and I would say in this population include very impressive findings. First, the GEN-1 plus neoadjuvant chemotherapy demonstrated no dose limiting toxicities and is safe up to the highest dose tested at 79 milligrams per meter square. The investigators in the oversight committee, that’s DSMB, did not find any significant toxicities associated with GEN-1. There are clear dose-dependent bioactivity and efficacy findings among the patients treated in the protocol. The clinical findings included a partial or complete response in 86% of patients. The surgeons were able to completely remove all visible tumor and outcome known as an R0 resection in 100% of patients treated with the highest dose. Distinct immunological changes in the tumor micro environment appear to be prone immune in 75% of patients, PFS importantly following this clinical result. PFS is projected to be over 21 months. Historically, PFS is in this patient population is approximately 12 months. Now, based on these findings in November 2017, we announced the submission of a Phase 1/2 clinical trial protocol to the FDA for the localized treatment of ovarian cancer. It’s an open label randomized study called the OVATION II study. We plan to treat the first 6 patients in the GEN-1 arm at 100 milligrams per meter square, that’s 30% – approximately 30% greater than the previous dose by the last dose that was treated, last cohort that was treated with the highest dose in the last study. So, the study will start with 100 milligrams per meter square, followed by a continuation of the selected dose in the Phase 2 portion in up to 130 patients. The entry criteria and treatment protocol are the same as the prior OVATION I study with one major addition. Following debulking surgery, patients will continue to receive up to 9 additional intraperitoneal doses of GEN-1, this will be a maintenance therapy. Our hypothesis is that continuous stimulation of the immune system after surgery may provide a further beneficial effect by delaying progression. Before we expect to initiate enrollment in this Phase 1 portion by June just a few weeks away and anticipate initiating Phase 2, the Phase 2 portion of the study in the first quarter of 2019. This will be an open label study we expect to report data periodically throughout 2019. Now, we are excited with the GEN-1’s potential as our PIs. As an example, in March 2018, Dr. Premal Thaker, the lead principal investigator for our GEN-1 development program presented – made a presentation entitled Ovarian Cancer: New Horizons and Treatments at an investor event in New York. Dr. Thaker’s presentation highlighted GEN-1 is a novel approach designed to deploy IL-12 without the toxicities associated with the recombinant form of the protein and outline results from the OVATION study. Our presentation noted immunological changes consistent with the ability of GEN-1 to increase peritoneal levels of IL-12 and its downstream anticancer cytokines with little changes in systemic circulation and no systemic toxicities. If you are interested, presentation can be found on our website. Now, before turning the call over to our CFO, I would like to say that I expect 2018 to be an important, if not transformational year. I think on our last call, I said this is our year. One way, our focused development efforts for ThermoDox in Gen-1 will make significant progress achieved with operational excellence and backed by responsible financial and capital management. Now, with that to discuss our financials, I will now turn the call over to Jeff. Jeff?
