Thank you, Ben, and good afternoon everyone. As we highlight in our press release, the second quarter include a many important strategic accomplishments for Inovio. Today the results further showcase the value and versatility for the company’s technology in both cancer immunotherapy and infectious disease. In this call, I am going to go over four topics with you today. First, I’ll discuss the positive Phase III clinical trial progress for VGX-3100 for cervical dysplasia. Second, I’ll highlight the expansion of our anal dysplasia indication for the lead product VGX-3100 increasing the overall product value. Third, I’ll provide an update on our immunooncology pipeline, and something I'm sure most of you being extremely excited about, I’ll update you on our GBM Phase I/II, INO-5401 study for which we dosed our first patient in July. And lastly, I’ll update you on significant data and advancements in our infectious disease programs. You've heard me state our goal for HPV treatment before. We want to own it from pre-cancer via cells to cancers with our partner MedImmune. HPV infection is the most frequent sexually transmitted disease and represents a significant commercial opportunity for VGX-3100 and MEDI0457. For our Phase III cervical dysplasia trial, I'm very pleased to report that enrollment remains on track for REVEAL 1. We have already opened 70 sites across 16 countries as of the end of June and we anticipate opening approximately 90 sites globally by the end of August. As a reminder, REVEAL 1 which is the primary portion of our Phase III study for treating women with high grade cervical dysplasia is scheduled to enroll 198 patients by very early part of next year. We will then immediately begin enrolling for REVEAL 2, the confirmatory study of the Phase III trial, where we were also involved 198 patients. While REVEAL 1 and 2 have different start times they will close at the same time. That’s because REVEAL 1 has a study follow-up through week 88, while REVEAL 2 has follow-up through week 40. Taken together, we expect all data from both studies to be available in 2020. Second point on today's call is that in our last quarter we opened our third indication in our go to own HPV treatments. So we now have ongoing late stage trial for cervical dysplasia and mid stage trials for vulvar dysplasia and anal dysplasia all caused by the HPV virus infection. Treating this broad range of indications is important because we are expanding the potential commercial value of our lead product VGX-3100. More specifically, we are very confident in VIN and AIN trials because of our cervical dysplasia Phase II data already show clearance of cervical lesions and elimination of HPV virus. So HPV virus clearance was something truly exciting and valuable as no other company has been able to demonstrate this previously. We now look forward to demonstrating this efficacy again in Phase III trials for cervical dysplasia and bringing VGX-3100 to the market. Just to touch further on the new indication of anal dysplasia, this HPV cause diseases is the precursor to anal cancer which is estimated to cost more than 1,100 deaths in the United States in this year alone. Just like VIN, we expect to obtain orphan drug indications for AIN which would increase the overall value of VGX-3100. Approximately half of men and women who have this disease also have HIV infection. So we have already initiated our compact 24 patient open label Phase II efficacy trial in HIV negative patients and have already dosed our first patients and the recruitment is rapidly ongoing. Yesterday, we announced that we have partnered with NCI-funded AIDS Malignancy Consortium or AMC to evaluate VGX-3100 for the treatment of anal dysplasia in HIV positive patients. AMC will conduct and pay for the trial. The requirement for this multi-side open label Phase II trial is already ongoing and will enroll approximately 75 patients. I’ll state here again that anal dysplasia represents a great commercial addition for VGX-3100, a game changing solution to a truly unmet medical need. We expect both of these anal dysplasia Phase II study and our vulvar Phase II trial to have an early efficacy data available in 2019. With these efficacy data at hand, we plan to obtain orphan drug status for VGX-3100 for anal and vulvar conditions truly thereafter. Let me state again our overall goal here. Inovio will become the go-to immunotherapy solution provider for all major HPV related conditions and specifically precancers caused by HPV, while working with our partner MedImmune for HPV related cancers. That’s covering both ends of the HPV diseases field. Moving to our immunooncology, I want to first speak about MEDI0457. As many of you are aware, MedImmune is evaluating MEDI0457 in combination with durvalumab as approved PD-L1 checkpoint inhibitor in patients with recurrent metastatic HPV-associated head and neck cancers in a clinical trial. In terms of an early indicator of things to come, let's review the data that was presented at SITC last year. In a Phase I model therapy study of MEDI0457 in 22 HPV positive patients with head and neck cancer, MEDI0457 generated robust antigen-specific CD8 killer T-cell responses in most treated patients. In particular of interest, one patient in that trial did develop a progressive disease at 11 months into the study and subsequently received a PD-1 checkpoint inhibitor. What’s truly exciting is that one patient has sustained a complete response or cure or remission in layman's language after only four doses of a checkpoint inhibitor treatment and continues on anti PD-1 therapy with no evidence of cancer 24 months after the initiation of a PD-1 inhibitor and counting. While no one gets too excited by one patient data even as impressive as this one. We must also remind ourselves that the anti PD-1 therapies alone have shown overall response rate of about 15%. So we expect to have additional efficacy data in the future from this Phase I patient group to shed an additional light into this data. And of course, we're all waiting for the Phase II data from the durva combination study MedImmune is currently conducting. Furthermore, MedImmune is expanding the testing 457 durva combination therapy to other cancers associated with HPV infection in a separate Phase II clinical study. MedImmune has recently posted on the clinicaltrials.gov its plan to test this combination therapy in a separate open label Phase II study in patients with multiple recurrent metastatic HPV-associated cancers, including cervical, anal, penile, vulvar, and vaginal cancers. This trial, which has been sponsored and conducted by the MD Anderson Cancer Center, is very important. What does this mean for Inovio? Such expansion of cancer targets is great for Inovio since this will bring about additional milestone payments to us in the near future and a greater royalty payment once the product is on the market. While we would not be providing any updates from MEDI on the enrollment and potential milestones associated with this trial at this time, we do anticipate the trial to begin in the third quarter and we'll provide an update after the study has officially begun enrollment. Shifting to our other immunooncolgy programs. We are very excited to have dosed our first patient as part of our Phase I/II trial in patients with newly diagnosed glioblastoma or GBM. This is an important step forward in Inovio’s plan to use the T-cell generating therapies in combination with PD-L1 inhibitors for GBM and other multiple cancers to improve overall efficacy. In pre-clinical studies combination of Inovio T-cell generating therapies along with checkpoint inhibitors have shown to strength tumors and improve overall survival of tumor bearing animals. In this GBM trial, our goal is to increase the overall survival of the patients facing a diseases were neither a standard-of-care clinical outcome have not changed in a clinically symptom way in a more than a decades. This efficacy trial design to evaluate Inovio’s INO-5401 T-cell activating immunotherapy in combination with Regeneron 2010, a PD-1 inhibitor developed by Regeneron pharmaceuticals. One of the primary efficacy endpoint is overall survival. We will also measure PFS or progression free survival. This initial enrollment rate is any indication which fact that enrollments go extremely well. We have six clinical sites already open and actively recruiting in the U.S. where we expect to open up to 25 sites. Overall, this open label trial renewal 50 newly diagnosed GBM patients. This strong enrollment rates should move our anticipated interim readout such as the six months PFS in this study to 2019. Moving now to the sister efficacy trial for INO-5401 in metastatic bladder cancer. This study is being run in combination with Genentech PD-L1 inhibitor atezolizumab and is very close to dosing the first set of patients. We have posted the Phase II study design on clinicaltrials.gov and we plan to open roughly 25 sites in the U.S. and Spain. The primary endpoint of this Phase II study will be ORR, T-cell immune responses and safety. The enrollment has begun and we should have interim efficacy Phase II readouts in 2019 as well. While speaking about our immunooncology programs, I have a couple of updates in INO-5150 our prostate cancer product candidate. We presented a poster ASCO this June, where we showed a clinically meaningful PSA stabilization post-dosing of INO-5150 in patients with no documented disease progression during the study, in particular of the 61 patients, 77% demonstrators strong T-cell immune responses. Looking ahead, additional analyses are underway to confirm the correlation between the immune responses and clinical benefit. Here I'm very happy to report that our prostate cancer study was recently accepted for presentation at a major oncology conference in the fall. We had an very successful in the past attracting valuable partnerships and collaborators with big pharma and biotech company and we remain an active outreach and discussions with the wide range of companies looking for combinations therapy agreements, or licensing opportunities with our pipeline for R&D product, especially for INO-5150 and INO-1800, both of which successfully completed Phase I trials. Both of these products address two of the largest therapeutic markets out there. We already touched on the potential impact of INO-5150 and prostate cancer in our hepatitis B therapy INO-1800 for which recent Phase I result shows it led to a generation of T-cell that recognized key HBV antigens and reacted by making antiviral cytokines such as Interferon gamma, a protein believed to be linked to clear – linked to clearance of HBV from the liver. We look forward to turning those active partnering discussions into valuable agreements in the future. Finally as we previously reported we are also in active collaboration with the Parker Institute to identify and began the first set of cancer combinations trials that complements our checkpoint combination strategy before year-end. Stay tuned for more updates later this year. Turning now quickly to our broad infectious disease platform. As you recall, early in the second quarter, we announced a $56 million partnership in funding with CEPI under, which Inovio will develop and CEPI will fully fund our vaccine candidates against Lassa fever and MERS through the end of Phase II. The ultimate goal of these development plan is to successfully complete Phase II trials and create a stockpile of these vaccines for future pandemic countermeasures and bring additional early revenues from the stockpile. I'm pleased to report that Inovio and CEPI are moving together with a sense of urgency on developing these products for which there excess no vaccine in both pre-clinical and clinical preparations, all with the goal to move into a later stage trials as rapidly as possible and we gain approval for mergers they use. Focusing specifically on our MERS vaccine with CEPI and other external funding, we are already moving in a raising speed. We recently reported positive Phase I MERS vaccine results from our U.S. trial funded by the U.S. military the results showed that the vaccine was well tolerated and about over 90% of treated patients achieved overall high levels of antibody responses and robust T-cell responses. The – IVI under Phase I/II MERS vaccine study should also start in the third quarter and Korea, leveraging the results from this study, we’re working to advance our MERS vaccine into a field Phase II testing in the Middle East in 2019 with full CEPI funding. Staying on our IV infectious disease team, we’re in the process of completing study visits for 160 persons Zika vaccine study in Puerto Rico and we were targeting a study completion and data report on this study in the fourth quarter. There's also been a significant progress on our HIV vaccine PENNVAX-GP which is designed to generate both antibody and T-cell responses and cover multiple HIV strengths globally. In May long-term data was presented that showed as global vaccine and development maintained strong and durable memory immune responses at month 12 but the trial of four, six months after the after the last dose in a Phase I clinical study. This is a significant data further supporting our earlier finding that PENNVAX generated the highest level of T-cell and antibody immune responses rates ever demonstrated in a clinical study by in HIV vaccine. We expect to reform more HIV vaccine data and trial initiations before the year-end. Overall we expect to publish several papers in 2018 from our Phase I data from our Ebola, HIV and MERS vaccine studies. In all of these studies we have consistently demonstrated over 90% of immune response rates across the trials while maintaining a favorable safety profile. I'm going to stop here to turn it over to Peter Kies our CFO, who will discuss our second quarter financials. Peter?
