Analyst · Ladenburg Thalmann. Your line is now open
Thank you, Doug and good afternoon everyone. I appreciate everyone taking the time to join us this afternoon. This was my first full quarter with pSivida, and with each passing month, I become more impressed with the team and the opportunities afforded by our proven and well-validated science. At the same time, I continue to believe that our technology is an undervalued asset despite having developed 3 of only 4 FDA-approved, sustained release treatments for back of the eye diseases. We are working very hard to change this situation and have made solid progress since we last talked in early November. Over the next several quarters, we have three overarching objectives for our company. First, we expect to complete European Union and U.S. FDA registration filings during 2017 for our Durasert 3-year uveitis product. Second, we expect to continue the recent progress of several programs using our unique Durasert sustained release technology. And third, we are striving to add at least one additional collaboration partnership with a drug manufacturer utilizing Durasert. Achieving these objectives in a cost-efficient manner is paramount to our team. One of my first acts as CEO was to pre-prioritize pSivida’s development program profile from one that was higher risk, longer term in its focus to one that is now moderate risk and achieves results near term. We have several significant data and regulatory milestones this year and I believe achieving these milestones should benefit our shareholders. Our Durasert 3-year treatment for posterior segment uveitis is our most advanced clinical program. Posterior segment uveitis impacts approximately 80,000 to 100,000 patients in the United States and another 80,000 to 100,000 patients in Europe. We have few options to treat this chronic inflammatory disease, which is the third leading cause of blindness. The Durasert uveitis second Phase 3 study met its enrollment target and the timing for the readout is planned by the end of second quarter. If you recall, the FDA required two Phase 3 studies for filing, and the first Phase 3 study met its primary efficacy p-value of less than 0.001 and yielded safety data that is consistent with the known effect of ocular corticosteroid use. We are very pleased with the primary efficacy and safety results at 6 months and the safety and durable efficacy results at 12 months. We remain optimistic the second Phase 3 study readout will be positive due to the robustness of the first Phase 3 trial data and the fact that trial designs are similar. As we discussed during the fiscal first quarter conference call, the European regulators required us to submit a pediatric protocol prior to the EU submission. We submitted the protocol. We received their comments and we expect to have final follow-up discussions during the next coming weeks. The end result is that we continue to expect to file the EU application during the second quarter of calendar 2017. In the U.S., we expect to file the NDA during the second half of calendar 2017. We have a number of Durasert technology product development opportunities, including our next generation Durasert bio-erodible, shorter duration treatment for posterior segment uveitis and for using collaborations with other drug manufacturers with their small molecules. We recently conducted market research for both our 3-year Durasert for uveitis and 6-month bio-erodible for uveitis. Physicians were very positive about Durasert’s proven ability to deliver a consistent daily micro-dose of a corticosteroid. The consistent daily micro-dose is believed to be one of the reasons behind the efficacy results we are seeing from the clinical studies. In addition, the physicians were impressed with the product’s ability to prevent recurrent flares that often lead to blindness. Further, our market research also covered physicians’ level of interest in the 6-month bio-erodible for uveitis. That feedback was also very positive for the need for such a shorter acting product. As a result, this research has enhanced our confidence and the market potential for Durasert 3-year uveitis once we receive approval. And in addition, it has also reinforced our prioritization of the 6-month Durasert bio-erodible for uveitis programs and we are conducting formulation testing now. Our objective is to begin preclinical safety and PK studies of this product in the second quarter of calendar 2017. We are also initiating efforts to form collaborations with other drug manufacturers for combining their small molecule drugs with this shorter duration form of Durasert to address patient needs in other indications. Another clinical program underway is the Durasert implant for severe osteoarthritis of the knee. As we have reported, the Hospital for Special Surgery in New York and pSivida announced the opening of an investigator-sponsored IND of Durasert to treat severe OA of the knee. The Durasert implant is designed to provide long-term pain relief for severe knee OA, which if affected could potentially result in the delay of knee replacement surgery. To-date, 5 patients have received the implant and the Hospital for Special Surgery expects to have the final patient implanted during the next month. While a safety and tolerability study changed from baseline in weekly mean of pain intensity scored at rest during activity and at night will be assessed weekly through 24 weeks. We are currently in discussion with HSS about the next steps for this program. Turning to our TKI program for wet AMD, the evaluation of additional TKIs are underway and we have identified multiple suitable TKI candidates for further formulation work. We have determined that pending the evaluation of TKI candidates, we intend to advance this program only through the development of a corporate partnership. Finally, there is our Tethadur preclinical program that applies proprietary technology to achieve the sustained release of large molecule, such as biologics, through a silica-based technology. Preclinical activities on this program are continuing and we are implementing a strategy to pursue partnerships to advance the program’s development. In addition to our ongoing programs, we have also taken steps during the past few weeks to expedite potential collaborations based on our proven Durasert technology with other drug candidates. Deb Jorn, who has joined pSivida in November, is heading up this effort, and she and the team are focused on establishing additional new collaborations and EU outlicensing partnership and preparing for the U.S. launch of our Durasert 3-year uveitis program. Once again, our objective is to enter into at least one new additional collaboration agreement prior to the end of the current calendar year. Before I turn the call over to Len, let me summarize why we are excited. First, on the regulatory front, we plan on submitting the EU marketing approval application for our Durasert 3-year treatment for posterior segment uveitis in the second quarter of the current calendar year. And in the U.S., we continue to expect to submit the NDA in the second half of the calendar year. Second, we will be announcing the results of our second Phase 3 clinical trials in posterior segment uveitis by the end of the first half of calendar 2017. Again, we feel very good about the prospects for a positive outcome of the study due to the positive results of the first Phase 3 study. Third, we are also looking forward to the implantation of the 6 patient for OA at HSS, the data evaluation and then working with HSS to determine the next steps. And lastly, Deb and her team continue to foster relationships with potential collaboration and outlicense partners. Our goal is to enter into at least one additional collaboration agreement with drug developers for our Durasert technology and an EU out-license for our 3-year uveitis product. We are also making very solid progress on both those fronts. I will now turn the call over to Len Ross for a brief review of our first quarter financials. Len?
