Analyst · Morgan Stanley. Your line is open
Thank you, Blaine. Good morning, everyone. And thank you for joining us. We kicked off 2018 with the momentum, drive, and ambition, which are key characteristics of the team here. We're excited about our prospects for the year and our efforts throughout the first quarter are moving us closer to our goal of building a sustainable biopharmaceutical company. We remain optimistic that we will secure approval and launch our lead drug, Amikacin Liposome Inhalation Suspension, or ALIS for adult patients with treatment refractory nontuberculous mycobacteria, or NTM lung disease caused by mycobacterium avium complex, or MAC. ALIS has the potential to be the first ever approved inhaled therapy to treat this disease. We accomplished an important milestone in this process with the filing of our NDA with the U.S. Food and Drug Administration at the end of the first quarter. I'll dive further into the impact this will have on timing for a potential approval and launch shortly. I would like to take a moment to acknowledge the team for their efforts in accomplishing this goal on time with the highest quality. To remind you, the disease we're fighting is a rare and progressive pulmonary infection associated with irreversible lung damage and declining lung function. We estimate that as many as 30% of NTM MAC patients fail treatment when using the off label antibiotic regimen that is the current standard of care, and we are aiming to offer an important treatment to address these circumstances. The file with our NDA was based on the full six month data from our INS-212 study. Recall that this study evaluated ALIS plus guideline-based therapy, or GBT, versus GBT alone, with the primary endpoint of culture conversion by month six. We achieved that primary endpoint unequivocally with a p-value of less than 0.0001. Results show that the addition of ALIS to GBT led to culture conversion by a 20% margin over GBT alone or 29% of patients on ALIS plus GBT converting within six months of treatment. Our robust clinical program was designed to gather additional information on the potential long-term clinical advantages of ALIS. To remind you, patients who culture converted in 212, are continuing in the trial for an additional 12 months of treatment. Patients, who did not culture convert, have the option to enroll in our INS-312 study in which all patients receiving ALIS plus GBT. The solid top line results seen in the 212 study were corroborated by the additional positive data from these two studies that we shared earlier this year. First, the interim culture conversion data from the 312 study echoed what we saw in 212 with 28% of patients previously on GBT alone achieving culture conversion by month six in the study. This rate of conversion was similar to what we observed in 212 at month six demonstrating consistency, reinforcing our confidence in the strength of the clinical data set we used in our NDA submission. Second, we observe the benefit in 212 in patients on ALIS plus GBT from longer-term treatment beyond six months with 12% of prior nonconverters achieving culture conversion by month six in 312. These data further support the treatment of patients for at least a year results in more patients achieving culture conversion, which we believe is an important aspect of the value proposition of ALIS. As a reminder, current guidelines indicate that once the patient culture converts, they remain on therapy for an additional 12 months. We also know through market research that many patients remain on guideline-based therapy for much longer periods of time. In fact, the median time on GBT for patients entering into the 212 study was more than four years. Third, the 212 extension study has also showed durability of culture conversion is substantially higher for patients receiving ALIS plus GBT versus those patients treated with GBT alone. Durability of culture conversion is of particular importance as this is a focal point for full regulatory approval. The 212 interim data showed the durability of culture conversion three months off of all the treatment was substantially higher in the ALIS plus GBT arm at 61% compared to GBT alone at 0%. We believe an important aspect of the full approval of ALIS will be the FDA's examination of durability of culture conversion 3 months off all treatment. While these data were not included in our NDA submission, they are public and we are prepared to discuss these findings with FDA, if requested during the regulatory review process. And finally, we believe these studies demonstrate a consistent and acceptable safety profile across both studies, as we previously shared serious treatment emergent adverse events observed in INS-312 are similar to those in INS-212. The safety profile remains consistent with that scene with the use of other inhaled antibiotics. Let me remind you that both the INS-212 and INS-312 studies remain ongoing. We anticipate the INS-312 study to be completed with topline data available sometime in late 2018. Let me spend a few minutes on an exciting event for us coming up in a few weeks, the American Thoracic Society International Conference, or ATS taking place May 18 through May 23 in San Diego. Awareness of NTM continues to grow across the treating community of health care providers and ATS will provide another opportunity for us to further educate the treating community about our disease awareness efforts and our clinical results. First, we'll have an oral presentation outlining the results of our Phase III study of ALIS for the treatment of NTM MAC. These results will be discussed on Tuesday, May 22 by one of the principal investigators of the CONVERT study. Second, we will have poster presentation detailing results on the 6-minute walk test, patient reported health outcomes, open label study results and predictive identification of individuals at risk for NTM lung disease. We look forward to sharing these additional data with you and importantly, to unveil this data at a forum, which has increasingly focused on NTM and how to address the challenges associated with this disease. Third, there will be an oral presentation of an investigator-initiated open label trial of ALIS in M. abscessus lung disease. Finally, while at ATS, we will continue to interact with thought leaders to gather insights and further enhance our understanding of the disease and share learning’s from all of our work in the field today. These conversations continue to be important in building disease awareness and guiding us in our development of this important potential new treatment option. As I mentioned earlier, we've made great progress on the regulatory front for ALIS with the end of March U.S. NDA filing under Subpart H with the division of any infective products. We should know by the end of May or early June when to expect the PDUFA decision, but we anticipate a six month priority review by the agency. This should result in a PDUFA date at the end of the third quarter. As Roger will discuss in a moment, we are currently planning for a potential commercial launch at the start of the fourth quarter. We are also expecting and preparing for an advisory committee meeting prior to the PDUFA Gold date consistent with the FDA's practice of convening advisory committee meetings in connection with the agency's review of novel products in therapeutic areas with unmet need. We will continue to prepare for an AdCom and look forward to the dialogue. Let me spend a moment on the progress of our geographic expansion. In line with our focus on Japan, as the next priority market, efforts on this front have also advanced very well over the past few months. I just returned with the team from a fruitful trip to Japan, where we met with over a dozen key opinion leaders in connection with the Japanese Respiratory Society Meeting. This is part of our ongoing effort to further build awareness around the disease to support our geographic expansion strategy. We also gain further understanding of the local perspective on the treatment of NTM in Japan. The prevalence of refractory NTM lung disease is higher in Japan than elsewhere in the world with approximately 15,000 to 18,000 refractory NTM MAC patients receiving treatment more than are currently identified in the U.S. A process to advance the data package and filing strategy with the PMDA, including pursuit of orphan drug status is ongoing. We look forward to providing further updates on our progress in Japan throughout the year. Turning to Europe. Compassionate use programs in several European countries have given a number of patients access to ALIS. Following a successful U.S. approval, we intend to establish a named patient program in Europe to allow access to the drug, while this program will be limited, nonetheless these patients are fully reimbursed and our ability to treat them broadens our relationships with the treating community across Europe. As you can see, we're rapidly moving ahead with the preparation for the regulatory review process the build out of our precommercial organization and geographic expansion. These efforts will help to support potential U.S. approval, a successful U.S. launch later this year and the global expansion of our organization. The Insmed team is also working to advance a number of other programs in rare disorders with INS1007, our next area of focus. As we've noted previously, the program's initial focus in non-CF bronchiectasis has been a particular interest to the NTM and CF treating community due to the significant amount of overlap in these patients. Development activities for INS1007 continue to advance and we expect to accelerate these activities in the second half of this year. We look forward to sharing more details as these programs advance. Let me pause here and turn it over to Roger now for an update on our commercial activities followed by Paolo, who will cover our first quarter financials. Roger?
