Thanks, Andre’a, and thanks for everyone for joining us for our second quarter earnings call. Just to help remind some of the new folks on the call today, Abeona is developing rare disease gene therapies and plasma protein treatments for patients with rare diseases. We previously reported we have a focus in diseases that affect the central nervous system, particularly lysosomal storage diseases such as Sanfilippo syndromes and Batten disease. These programs were initially licensed at Nationwide Children's, Hospital which has a long history in AAV, particularly gene therapy and a history of other successful biotechnology gene therapy company. And our Batten disease program also comes out of the University of Nebraska Medical Center. Both of these use very similar strategy, using adeno-associated virus that’s delivered by intravenous injections that treats the whole body of the disease, just to refresh. We’re working on these lysosomal storage diseases. The lysosome is essentially the garbage factory of the cell. It’s responsible for chewing up a lot of the different sugars and proteins to make metabolize for the cell, children that are born with these inherited autosomal recessive genetic disorders have a deficit in the enzymes and specific sugar metabolism pathways and unfortunately can’t break down these sugars. So our therapeutic strategy is to give these AAV – the genetically modified AAV viruses to basically replace the enzyme that’s been deficient so that these sugars can then be broken down. Pre-clinical data in these programs have demonstrated complete correction of the survival deficits. Keeping in mind that 70% of these children are not – do not reach the age of 18 particularly in Sanfilippo syndrome and there are no approved therapies on the market currently. So when we looked at the original pre-clinical data that demonstrated complete correction of the survival deficits, normalization of the muscular and cognitive functions, we’re very excited by the process. I think as the market has shown in the past two or three years, there’s been a broad level of excitement around the promise of these AAV gene therapies and hope that they offer potential treatments and therapies for more people affected with these rare diseases. In support of our clinical development programs, it's important to note that we have with our partnering hospital a Natural History study that was conducted. I'll focus just for a few minutes on why we think that this is important to bring up on an earnings call. As we have two clinical programs now for Sanfilippo syndromes type A and type B, also known as mucopolysaccharidosis disease type III, this Natural History study was conducted in 25 patients to 1 year of follow up evaluations. The Natural History study – and the manuscript has been submitted and it’s currently under review. This will evaluate the outcome measures for the clinical trial for both ABO-102 and 101, our clinical programs. It’s an important part of the clinical development plan as we hope to enroll 15 to 33 patients globally with three sites in the United States, Spain and Australia in an effort to accelerate the global access to these obviously much needed therapies for these kids. As a reminder, there are no proof therapies for treatment for Sanfilippo syndrome. And as importantly recent failures in some other enzyme replacement trials have really demonstrated that without that sufficient efficacies there are fewer treatment options for patients with these rare diseases. So now there is an additional focus on the promise of AAV gene therapies in what they may be able to offer. Beyond having the Natural History study [indiscernible] validate a lot of the outcome assessments by the instruments needed to evaluate whether these gene therapy treatments are potentially going to provide benefit. We measured; the hospital measured the early stages of biopotency as well as cognitive learning functions, muscular functions through the Natural History study. As far as some of the recent operating highlights, we have announced – we did announce on May 17 that we did treat the first patients in the Phase 1/2 trial for ABO-102, single treatment gene therapy for patients at Nationwide Children's Hospital and then later announced that we did receive in May the IND allowance for ABO-101 for MPS IIIB also at Nationwide Children's Hospital. And we’re very pleased to announce on August 2 an early but initial update on subjects enrolled in this trial, at the time we had enrolled 2 subjects and through 30 days of follow-up appointments that treatments have been well tolerated with no safety concerns identified. And we did see some early encouraging signs of biopotency with reductions in urinary and CSF GAG, specifically heparan sulfate. So heparan sulfate, you’re going to hear this throughout our talks throughout the next two years and do some other programs that are out there. It is a focus on how you assess early biopotency, which is a measurement of GAG, so GAG central glycosaminoglycans specifically in MPS IIIA and IIIB, the sugar that’s involved with the heparan sulfate, for example MPS VII which is [indiscernible] sulfate. So when you look around in this space and you see people trying to report measurements of biopotency, it’s really a reduction in urinary heparan sulfate for us and so we saw some of that as well as potential disease-modifying effects in the liver and spleen. So we also announced on August 4 that we had received the European regulatory approval from the AEMPS for a Phase 1/2 trial to be conducted at Cruces Hospital in Bilbao, Spain. This is opening our second clinical site for ABO-102. Again, as a reminder, for the global development plan, our thoughts have been to try and enroll six to nine patients in the US and then in Spain and also in Australia in an effort to again try to accumulate 15 to 30 patients worth of data in an effort to go directly to commercialization. And we believe that with some of the early signs in biopotency that we’re seeing as well as the Natural History study and the data that’s provided us, we are on a good path to see potential signs in the next six to 12 months and look forward to reporting that data. On August 9, we announced a collaboration with EB Research Partnership and EB Medical Research Foundation and Stanford University for the development of treatments for recessive dystrophic epidermolysis bullosa, although it’s known as RDEB. Clinical results for the lead program, EB-101, were recently presented at the opening Plenary Session of the Society for Investigative Dermatology in May 2016, and Investigators at Stanford are currently recruiting patients for a Phase 2 clinical trial of EB-101 in adolescents age 13 and older to determine the effect of type VII collagen gene corrective grafts on wound healing efficacy. So in one of the – as a gene therapy and rare disease company, obviously have been looking around in this space for programs that we feel fits within our warehouse. We thought that epidermolysis bullosa or EB which is also known as butterfly skin, there are probably one of the worst diseases that I personally have seen, these children, when they have a injury to the skin and an injury being something as simple as bumping up against a sharp edged results in skin blistering and falling off. So again, the skin in the largest organ in the body and when having a lot of your skin fall off is clearly a devastating disorder. So epidermolysis bullosa is a devastating genetic skin disorder that impacts children and again these are skin blisters and erosions all over the body. RDEB is the most chronic or most severe form of this chronic skin blistering disease and they have these open and painful wounds that sometimes stay open for years. They have joint contractures, esophageal strictures, their joints will start to fuse or to fingers and toes bringing abrasions and certainly a shortened life span. Patients with RDEB lack a functional type VII collagen owing to mutations in the COL7A1 gene that encodes for collagen VII or C7. C7 is the main component of anchoring fibrils that attach the skin basically to the underlying structure. These patients suffer intense pain with again fewer or no effective treatments to reduce the severity of the symptoms. Along with the life-threatening infectious complications associated with this disorder, there are many individuals who will develop an aggressive form of squamous cell carcinoma. Our lead product, EB-101 has been shown in a Phase 1 trial to have significant benefits for the four patients in which we’re originally reported. So to talk just a moment, again, we thought that this was a very excellent gene therapy that we thought made a lot of sense for us to bring in, again as a rare disease company. The fact that it’s a late-stage clinical program is certainly very attractive to us, but really it came back to our core mission around trying to help patients with rate disease, trying to be champions of developing gene therapy programs where there are no approved treatments. So Phase 1 data around this was very compelling. Again, the risk for kids, each kid received six skin grafts at three months [indiscernible] showed a significant amount of wound healing as defined by 75% healing over baseline. And again, just to recall, sometimes these are wounds that these kids have lived with as an open wound for years. And when we talk about wounds, we’re not talking about a small scratch. We're talking about something that could be the size of your palm on a child’s back or forearm or shoulder that has been open and has been bandaged for again potentially years. The benefits were maintained through six months, again with about 70% showing significant healing in skin biopsy that came from the graft they had showed robust collagen expression [indiscernible] normal in appearance. So this is very good and the grafts of course were very well tolerated. And so now we're moving to a Phase 2 trial at the end of 2016 and into 2017 with Stanford University. As a comparable, this is certainly similar to other programs that have recently been improved, again showing a gene corrected stem cell, it’s the word we’re looking forward to having move forward into Phase 2 trials. One of the reasons again these kids have – with wounds that have been open for years, these costs can be upwards of $100,000 or more in bandages, so a horrible disease that we are happy to have helping and other gene therapy for. So as we look to the second half of 2016, and again having three clinical stage programs in MPS IIIA, IIIB and epidermolysis bullosa, we believe that the company is well positioned as a leader in the gene therapy space and to provide more benefits for our patients and our shareholders with these gene therapies. With that, I will turn it over to Jeff Davis to talk a bit about our quarterly financials.
