Analyst · Stifel. Your lines are open
Thank you, Steve. Good afternoon, and thanks to all of you who have joined today's call. With me today are Bob Brown, our Chief Scientific Officer and SVP of Research; and Jack Green, our Chief Financial Officer. The second quarter of 2016 was an exciting period for Dicerna as we formally rolled out our GalXC technology platform as a fully optimized and enabled drug discovery engine. By that, I mean that our efforts over the last few years have created the capability to fully silence disease-associated genes in the liver using a single subcutaneous injection delivered once monthly or even less frequently, and that we can do this reproducibly and consistently across any liver expressed gene across multiple therapeutic areas. During our Investor Day in June, we illustrated these capabilities with examples of GalXC molecules silencing 12 different disease-associated genes, including six demonstrations in non-human primates. These demonstrations include inhibitors of disease targets that will populate our pipeline going forward, and others that we expect offer significant partnering opportunities to Dicerna. The GalXC platform supports our long-term strategy to retain a full or substantial ownership stake and invest internally for indications with focused patient populations, such as certain rare diseases, and we see such indications representing opportunities that carry high probabilities of success, have easily identifiable patient populations, and a limited number of centers of excellence to facilitate reaching these patients. For more complex diseases with multiple gene dysfunctions and larger patient populations, we plan to pursue partnerships that can provide the enhanced scale, resources, and commercial infrastructure required to maximize these prospects. We continue to engage in such discussions and believe that the data we have generated to-date and that which we shared at our Investor Day strongly positions Dicerna to attract interest, not just from any potential partner, but the right strategic partner. Also during the second quarter, we dosed the first patient in our Phase 1 interventional study of DCR-PH1, our lipid nanoparticle formulated IV-administered compound for the treatment of the rare metabolic disease, primary hyperoxaluria type 1 or PH1. During the quarter we also continued to enroll PH1 patients in our PHYOS study, which is gathering important information about PH1 that we feel will provide valuable insights as we map out a long-term development path for this rate genetic disease and key area of unmet medical need. Toward that end, we have selected our subcutaneously-dosed GalXC clinical candidate for PH1, and expect to file an IND or CGA in late-2017. Dicerna expects to launch GalXC-based development programs for three candidates in 2016, and be able to launch three additional programs annually, utilizing our current capacity. The first of these 2016 programs is our GalXC candidate for PH1, and the launch is already underway as I just mentioned. The second and third 2016 launches are for a PSCK9 inhibitor in cardiovascular disease, and for an undisclosed rare disease program. The progress we have made with the GalXC technology has enabled us to broadly examine disease-associated targets across multiple therapeutic areas, including notable chronic liver diseases like NASH. Our ability to generate GalXC inhibitors in rodents very rapidly, often just 30 days, has greatly facilitated our ability to validate potential disease targets. In total, to-date we have qualified 29 disease-associated genes where we believe an RNAi based inhibitor could provide substantial patient benefit. These targets span the therapeutic areas of rare diseases, chronic liver diseases, cardiovascular diseases, and liver infectious diseases. The common thread among these targets is the expression of disease-associated genes in the liver. We are truly excited about the possibilities ahead of us with the GalXC platform. In our view, the well of opportunity to deliver innovative RNAi therapies to the liver is deep, not only for Dicerna, but also for the broader biopharmaceutical industry as well. We view the RNAi market opportunity supporting multiple entrants and multiple winners. RNAi provides the potential to develop therapies with monthly or less frequent dosing, which we believe can significantly impact patient compliance and health outcomes, and therefore the healthcare system more broadly. We are confident in the technology, and believe that choosing the right programs to invest in and bring forward will be key for Dicerna in executing on our strategy. Moving to our work in oncology, our clinical stage DCR-MYC program is in a Phase 1 study in a Hepatocellular Carcinoma or HCC, and in a focused Phase 1 expansion cohort at maximum tolerated dose, and pancreatic neuroendocrine tumors or PNET, where we have observed two clinically significant responses during dose escalation. We expect to release data on both indications before the end of 2016 and we expect that these data will inform a go or no-go decision on this program. As you can see, we have laid out an extensive pipeline growth strategy for the coming years and we remain extremely confident in our freedom to operate in the space and in our ability to execute on this strategy. I'd now like to turn the call over to Bob Brown, our Chief Scientific Officer, for some comments on the progress we have made in advancing our GalXC platform to this existing stage. Bob?
