Analyst · Stephen Willey from Stifel. Your line is now open
Thank you, Sara and good morning everyone. As Will mentioned, 2020 was a year of remarkable achievement for Insmed underscored by advancements across our pipeline. Let me now address our progress and next steps for each of our programs. First TPIP is a novel dry powder formulation of Treprostinil Palmitil, which is a product of Treprostinil. We believe TPIP represents an opportunity to harness the full potential of the prostanoid pathway. Let me start by drawing your attention to the top line data we shared just last week from our Phase 1 single and multiple ascending close dose trials in healthy volunteers. TPIP was generally safe and well-tolerated and showed substantially lower [indiscernible] and longer half-life and currently available inhaled treprostinil therapy. These findings support the continued development of TPIP with once daily dosing in-patients with PAH. For an in-depth review of these results, I encourage you to visit our website for the detailed press release and conference call webcast. Regarding next steps, we remain on track to advance to the next stage of clinical development, which will follow two paths in parallel. First, we will gather information on the impact of TPIP on pulmonary vascular resistance, or PDR, and over a 24-hour period in a handful of patients with PAH or Group 1 in an open label study. As planned, we anticipate sharing top line patient data from this study in the second half of this year. The second path will investigate the effects of TPIP on PVR and six-minute walk distance in patients with PAH over a 16-week treatment period. We plan to initiate this trial in the fourth quarter. In addition to those two studies in PAH, we're planning to initiate a separate study for Group 3 PH-ILD patients, in addition to our work, exploring a development pathway for TPIP and idiopathic pulmonary fibrosis, or IPF. We plan to use an up-titration dosing schedule to the maximum individually tolerated dose, exceeding 600 microgram once daily. Let's now turn to Brensocatib, a novel oral reversible inhibitor of dipeptidyl peptidase 1 or DPP1. We view Brensocatib as the cornerstone of our efforts to build a program around the DPP1 one pathway with enormous potential across a range of therapeutic areas. We saw several key achievements over the course of 2020, including the publication of our final results from our Phase 2 WILLOW study in the New England Journal of Medicine in September. As Will mentioned, we were also pleased to report that Brensocatib was granted breakthrough therapy designation by the FDA, as well as priority medicines or prime designation by the EMA for NCFBE. Underscoring the strengths of our Phase 2 WILLOW data, we were pleased to announce late last year, the initiation of Phase 3 ASPEN Study of Brensocatib in patients with bronchiectasis. As you may recall, the ASPEN Study is designed to confirm the positive results we saw in our Phase 2 WILLOW study and as such ASPEN retains many key elements of WILLOW. For a detailed overview of the trial design, I encourage you to review our R&D Day presentation, which remains available on our website. We look forward to sharing updates with you as the trial progresses. In parallel, STOP-COVID-19, an investigator initiated study of friends of captive in approximately 400 hospitalized patients with COVID-19 is now fully enrolled. As a reminder, this study is being conducted under the direction of Professor James Chalmers at the University of Dundee and across a number of hospitals in Scotland. Recall, that Professor Chalmers was also the principal investigator of our Phase 2 WILLOW Study. It is our expectation that Professor Chalmers will share data from the STOP-COVID-19 study early in the second quarter of this year, and we hope it will provide further validation of the DPP1 inhibition pathway, as well as important data regarding neutrophil functioning that could provide future clinical utility. At ASPEN and STOP-COVID-19 advance, we're working to extend our focus for Brensocatib to additional potential indications as we continue to build our program based on the DPP1 pathway. Beyond bronchiectasis we remain on track to initiate in mid-2021, a Phase 2 pharmacokinetics, pharmacodynamics multiple dose study to explore the appropriate Brensocatib dosing for cystic fibrosis patients. At the same time, we continue to advance our research efforts to support expansion to other neutrophil mediated indications across a range of therapeutic areas. I would like to take a moment to touch upon another exciting development opportunity for Brensocatib. In January, the publication cancer cell highlighted the role of Brensocatib in inhibiting lung metastasis of breast cancer in a mouse model. Cancer cell is internationally regarded as one of the top cancer research and oncology journals, and publishes articles on all aspects of cancer cell biology. The paper builds upon earliest suggestion that neutrophil extracellular traps or NETs may be important in cancer metastasis. Next, a highly damaging web structures started with DNA and proteases that trap microbes, but are also involved in autoimmune disease and cancer. Activated neutrophils can release NETs into their surroundings. Previous preclinical studies have shown that Cathepsin C in NETs play an important role in metastasis. Brensocatib directly inhibits Cathepsin C or DPP1 and interferes with NET production. In this cancer cell paper, they also showed that the administration of our drug Brensocatib was able to suppress lung metastasis in a mouse model. We believe this represents an exciting potential opportunity for Brensocatib in oncology, which is just one area where we think our compound can have potential clinical benefits. We are encouraged by this early result that suggests validation of the importance of the DPP1 pathway, and we will continue to advance our research efforts for Brensocatib in oncology. Let's now move on to our post-marketing frontline clinical trial program for ARIKAYCE. This program is designed to both support the full approval of ARIKAYCE in the U.S. as well as potential expansion into the larger frontline opportunity in MAC lung disease in the U.S., Europe, and Japan. These efforts support our overarching goal of shifting the treatment paradigm for patients suffering from NTM lung disease. The program involves two separate, but interrelated clinical trials ARISE and ENCORE. Earlier this year, we were excited to announce that the ARISE and ENCORE trials were initiated and began dosing patients in December of 2020. As a reminder, a more detailed look into the study schematics and designs can be found in the investor presentation available on our website. As sites open worldwide, we expect to provide an update on this program later this year. In summary, we made important advancements across our clinical programs in 2020. We remain excited and optimistic about the potential underlying our pipeline and look forward to sharing developments with you in the future. Let me now turn the call over to Roger to discuss some key operational updates. Roger?
