Thank you, Jeff. Good morning everyone. We have a lot to discuss today, so I’ll get right to it. Before doing so, I want to remind you, I’m joined today by Jeff Church, from whom you’ve just heard, our CFO and Senior Vice President. Dr. Nick Borys and Anwer, who normally would be with us for this call, are not today. They are attending on a business, but they will be on future calls, I can promise you that. So welcome once again to our quarterly earnings call, and to the new Celsion, the company that all at once, with the acquisition of EGEN, this marvelous science-based company in Huntsville, Alabama, all at once is a fully integrated development company with R&D capability from feasibility through NDA, with platform technologies in chemotherapy, immunotherapy and RNA therapy and clinical trials in Phase III, Phase II and Phase I, in some of cancers globally most important forms, we are extraordinarily well positioned. Celsion now has multiple opportunities to create value for our shareholders, and represents a development company. I’m sure that you will agree by the unique proportion. On the development front, as our recent news fore points up, we’re having an extremely productive year thus far, and one that I suspect will continue to demonstrate significant progress, not only with ThermoDox for primary liver and recurrent chest wall breast cancers, but also with our equally important immunotherapy and RNA platforms. If I can take the liberty now to quote one of our great presidents, “To Those, Whom Much Is Given, Much Is Expected” then I’d add, particularly this morning, with our EGEN acquisition, you should expect much from Celsion. So here is a shortlist. And it reminds the shortlist that what we will be reporting over the next 12 months. From our first immunotherapy candidate EGEN-001, which I’m going to refer to as GEN-1. By the end of the year, we’ll be reporting translational data from our Phase Ib study of platinum-resistant ovarian cancer patients, demonstrating the expression of IL-12, and the activation of an associated potent multi-mechanistic anti-cancer immune response. Whilst from the same study will be available early next year. We’re also fully expect to report regulatory support from our planned Phase II study in first-line ovarian patients in the first quarter of next year. In a second indication for EGEN-001, one that could very well become a priority for the company, we will be reporting substantial pre-clinical data in support of our planned IND submission for the GBM glioblastoma ovarian cancer indication. Again, we fully expect that the data will be followed by FDA agreement for a Phase I study in post-resection GBM patients. For this, we are targeting the second quarter of 2015. From our second product candidate, a PPC, that’s a polyethylenimine nanoparticle that has the unique capability for delivering Messenger RNA, as well as other long and double chain nucleotide sequences. From this second product candidate, we plan to report data from a non-human primate study. The study is designed to collaborate in the second species, data which reliably demonstrates highly priced and clinically very relevant Messenger RNA lung expression. Lung expression of RNA is a characteristic uniquely associated with our proprietary PPC delivery technology, making it a very attractive delivery platform. And from our ThermoDox studies, you should expect ongoing data from the DIGNITY study, which if it continues to show overwhelmingly positive tumor response results, we will approach FDA to discuss next steps. And if you recall from prior written agreements, we know that FDA will accept local tumor control as the registrational endpoint in this unfortunate highly refractory end-stage population. And of course we will provide regular DMC updates from our Phase III OPTIMA study in primary liver cancer, a study that is currently recruiting patients. Now for those of you who are new to our company, I’d like to spend a few minutes in our strategic asset acquisition purchase, the deal which by anyone’s definition is incredibly investor friendly. I’d ask Jeff to discuss the deal terms in a little bit more detail when he covers the financials. In June, we announced and completed our acquisition of EGEN, a privately-held company whose primary focus is the development of nucleic acid-based therapeutics for the treatment of cancer among other therapeutic areas. This transformation will then establish Celsion, as I have said, as a fully integrated oncology company. It provides us with programs and the leading edge of cancer research and with R&D talent and competences end-to-end, from drug discovery through to commercialization. With this deal, we have improved the depth of our technology and research base, and have created a new trajectory for Celsion in three distinct ways. First, we now have multiple technology platforms, three to be exact, from which to generate future growth. They include of course, our proprietary heat sensitive liposomal platform, exclusively we licensed – with exclusive licensee from Duke University, LTSL platform is the technology underpinning our ThermoDox product. TheraPlas is the second platform. TheraPlas is a synthetic non-viral nanoparticle for the delivery of double stranded DNA pharmacologic immunotherapy products, and for single or double stranded therapeutic RNA. And third, TheraSilence, a liposomal nanoparticle for the delivery of siRNA and miRNA or microRNA. Secondly, we now go to the pipeline that includes a robust pre-clinical development program in earlier stage research that represent potential leading edge technology to treat difficult disease targets. And third, we have multiple product candidates at the clinical level, which I will now review. Let’s start with ThermoDox. Our Phase III OPTIMA study is designed to evaluate ThermoDox in combination with standardized radiofrequency ablation or sRFA in hepatocellular carcinoma or HCC, sRFA for HCC. The study will enroll approximately 550 patients globally and up to 100 sites in North America, Europe, China and Asia Pacific. It is a two-arm, double-blinded randomized study comparing ThermoDox in combination with standardized RFA or sRFA, which will be standardized across a minimum of 45 minutes across all investigators in the study versus standardized RFA alone. The primary endpoint is overall survival. The study is pilot to show a 33% improvement in OS, and I want you to keep 33% in mind, we’re going to refer back to that in a minute. The statistical plan calls for two interim efficacy analysis by an independent data monitoring committee. The office spend is de minimis for these two lines. The support for OPTIMA is significant and comes from; one, an exhaustive retrospective analysis of the previous Phase III HEAT study; two, it’s based on convincing post-hoc OS data; and three, it’s further reinforced with prospective confirmatory pre-clinical data in computational models. Post-hoc findings and hypothesis supporting OPTIMA do not represent our view alone. The data were shared along with our RFA learnings, in particular, with HCC research community during major international medical conferences. In the final analysis, we have received full support, and I would say, share a great deal of optimism for the OPTIMA study with virtually all of the most important names in HCC research worldwide. I think with some modestly, I’d like to say that, we now know more about the use of RFA to treat the intermediate stage lesions in HCC than just about any company on the planet. What we’ve learned from the study is this. For tumors greater than three centimeters, RFA device limitations have to be considered. To be effective, and that is to fully destroy the tumor and create a clean margin multiple overlapping ablations creating longer dual times are required. When we say dual time, that is the achievement time greater than 45 minutes, also improves the heat radiant to a larger volume and allows for increased local ThermoDox profusion, and ultimately a high tissue concentration of doxorubicin. Longer times plus increased dox ensure a better outcome. The findings are convincing. The most recent clinical evidence supports this thesis. It comes from our June 30 quarterly Overall Survival sweep of the HEAT study patients. In this subgroup of 285 patients, who received standardized RFA treatment, 285 represents 41% of the total study, we noted an 57% improvement in OS in the ThermoDox plus sRFA arm versus standardized RFA alone, 57% improvement. I want you to reflect back in my earlier comment regarding the primary endpoint of Overall Survival that we’re planning for the OPTIMA study. In that case, we were looking for 33% improvement. So the evidence in our post-hoc analysis suggests that we should be able to meet that target quite easily, quite handily. So 57% improvement versus sRFA alone, that’s over two years improvement in survival. That’s pretty astounding. Two years. A bullet for wedding and graduation. If you recall, Nexavar or sorafenib was approved on just 11 weeks OS benefit. And while there should be caution since this is a retrospective analysis, these findings are nonetheless striking in that they have one remain constant over each of the six quarterly dead sweeps. They demonstrate impressive confidence with a p-value of 0.037. The magnitude effect is unequivocal. This is not a borderline improvement. Well wobble in the data could have an impact. These data are further supported by multivariate Cox Regression Analyses, which do not discount in anyway sRFA plus ThermoDox, the leading factor for the OS benefit. The goal of OPTIMA is to support registration in key liver markets worldwide. To that end, we’re working with multiple agencies, hopeful regulatory agencies to advance our global registration strategy. In addition to the U.S. FDA clearance that we received in the first quarter of this year, we have a received approval to commence the study in sites in Taiwan, Hong Kong, South Korea, Malaysia and Canada. And we have also submitted an application for accelerated approval to the China FDA, Food and Drug Administration. The CFDA has reviewed the HEAT study data, with Dr. Borys and myself, including the subgroup of patients treated in China and it’s committed to working with us to initiate the OPTIMA study in China as quickly as possible. In Europe, we are taking advantage of the Harmonization Process, which allows for a central and parallel approval of the key countries including Germany, France, Italy and Spain. In addition, we plan to meet with the EMA later this year to discuss our ThermoDox MAA or marketing approval filing strategy. Beyond HCC, we are evaluating ThermoDox in the Phase II DIGNITY study. A ThermoDox plus hyperthermia in recurrent chest wall breast cancer. As you know, we continue to report very impressive results in this, difficult to treat, refractory population, so patients post-hysterectomy, who have failed at least two lines of chemotherapy and have failed radiation before enrolling in our trial. In July, we reported updated interim findings demonstrating that a local response rate of greater than 50% has been observed in the first patients with refractory disease, notably with three complete responses. I’d also point out that these findings are consistent and have been consistent with the objective responses that we’ve seen in two previous Phase I studies accounting for some 27 patients. Additionally, we are supporting a broad range studies using HIFU to provide ThermoDox activation in multiple indications. The most advanced program is now recruiting patients in a Phase II liver met study in Britain, followed closely by a breast cancer study, which we hope to initiate in the Netherlands. Both of these programs are co-founded and co-funded in Europe by government grants. One grant of which is up to $10 million. Now I’d like to turn our attention to EGEN-001. EGEN-001 is our Phase II ready immunotherapy candidate for the treatment of ovarian and brain cancer. It is an IL-12 DNA plasmid encased in a PPC nanoparticle delivery system. The system promotes transaction of the plasmid into cells, which then use the cellular mechanism to enable persistent and durable local secretion of the IL-12 protein, the interleukin-12 protein, which lasts for several days or weeks depending upon the target. As many of you know, IL-12 is one of the most active cytokines for the induction of a potent anti-cancer immunity response. It acts through the induction of T-lymphocyte, a natural killer self-proliferation and has also shown an anti-angiogenic effect, and has demonstrated a potential in a variety of cancers as a recombinant protein and as a protein that’s manufactured ex vivo in fermentation plants [ph]. This ex vivo that’s outside of the body produced IL-12, and when used it locally systemically to treat cancers has poor pharmacokinetics and is associated with serious toxicities. Scientific evidence collected today have shown that EGEN-001’s potential to overcome these limitations by controlling the expression of IL-12 in vivo, we see very encouraging safety profile and similarly encouraging indications of efficacy. Phase I clinical studies have established the safe therapeutic dose, and have demonstrated strong disease control rates in a tough to treat platinum-resistant ovarian cancer population. 001 has been safely combined with first-line chemotherapies, carboplatin and docetaxel in platinum-sensitive ovarian cancer patients. While the end was small, we noted a positive disease control in OS rates in this population. We are currently completing a Phase Ib trial in platinum-resistant ovarian cancer patients, under direction of the GOG, that’s the Gynecologic Oncology Group. By year-end, we will be reporting translational data, demonstrating the expression of IL-12 and the activation of the associated potent multi-mechanistic anti-cancer immune response. In early next year, we should be able to assess an OS signal. The data today strongly support a rationale for advancing EGEN-001 into a Phase II combination trial with the goal of targeting first-line plus the standard of care or activation of immune response is frequently more effective for subjects whose immune system is healthier and less compromised by previous chemotherapy. We’re on track to meet with the FDA regarding our Phase II plan. We’re hoping to do so by year end, with FDA concurrence in the first quarter of next year, we could be treating patients in the second quarter. I’d also point out that applications for EGEN-001 extend beyond ovarian cancer. In parallel with our ovarian program, we are working on a second and perhaps the most exciting clinical research for the company and that is a development program in glioblastoma multiforme or GBM. As I have said, this could well become a priority for Celsion. As you know, a small well-designed study may provide for registrational opportunity or approval, we’ll see. Our pre-clinical studies have demonstrated that administration of EGEN-001 in the brain can lead to an IL-12 expression that lasts for at least one month. So we are fast moving towards an IND in this indication, supported by follow-on pre-clinical proof of concept safety and bio-distribution studies which are now in the last planning stages. Our goal is to submit an IND briefing book and protocol by year-end and plan for Phase I study in the first half of next year. The study design contemplates combining IL-12 immuno activation with the standard of care chemotherapy in post reception patients. OS of course would be an ideal endpoint, particularly in this population. You may also know that the EGEN-001 is a non-viral approach, which could accelerate or should accelerate, regulatory acceptance over our other approaches under development. Now I’d like to turn to EGEN-002, an RNA therapeutic based in our TheraSilence platform, which is at the concept stage. At this concept stage, setting the basis for partnering or collaboration. EGEN-002 is a combination of two unique molecular targets for cancer therapy and has the potential as a treatment candidate for lung cancer. The concept uses a two-pronged approach; a combination designed to inhibit tumor growth by anti-angiogenesis, and promote direct killing of the tumor with microRNA. We have demonstrated evidence of siRNA delivery and gene silencing into lung. And with this approach and look forward to advancing pre-clinical development of this program. Beyond our own clinical development efforts, we are also seeking to leverage the TheraPlas and TheraSilence platforms externally. You should know that we have a current joint development program focused on lung application of messenger RNA, the next milestone of which is to collaborate urine [ph] data in a non-human primate study. Some very exciting news could come from this project near-term. From our press releases, you know that we recently launched the commercialization of our reagent products based on these two validated platforms, that’s TheraSilence and TheraPlas, and believe we can generate most revenues from this business to help support our maturing oncology pipeline, but more importantly however, reagents sales to leading research and academic centers will serve to validate our proprietary non-viral vector delivery platform. So you can see we have a very active clinical development effort focused on three promising candidates, with the leading edge of cancer research, and we look forward to updating you on our progress. So now I’ll turn the call over to Jeff for a review of our financials. Jeff?
