"Based on what Aimmune has accomplished, the board and management are grateful for the tremendous contributions Stephen has made. We respect his very personal decision and appreciate the fact that his deep and sustained commitment allows us to spearhead a fulsome search for the right next CEO of Aimmune, an individual with significant commercial and strategic experience, to build upon what Stephen and the team have delivered to date. We have never been more excited about Aimmune's potential, and will work deliberately to identify and land our next leader while the team led by Stephen maintains focus on our 2017 and 2018 objectives," added Mark McDade, Chairman of the Board.Recent Corporate Highlights Announced Phase 2 Clinical Collaboration with Regeneron/Sanofi. In October, Aimmune announced a clinical collaboration with Regeneron and its strategic alliance collaborator Sanofi to study AR101 treatment with adjunctive dupilumab in peanut-allergic patients in a Phase 2 clinical trial. Regeneron will sponsor the trial, with Aimmune to provide clinical supply of AR101 and food challenge materials. The clinical collaboration will include the formation of an Aimmune-Regeneron/Sanofi Joint Development Committee. The planned Phase 2 clinical trial is expected to begin in 2018 with a proposed primary endpoint of tolerating a certain dose of peanut protein in a double-blind, placebo-controlled food challenge (DBPCFC) that will include doses matching and exceeding those being tested in current AR101 studies. The study also includes a proposed exploration of sustained unresponsiveness after discontinuation of therapy in another DBPCFC. Sustained unresponsiveness is achieved when, after a break in treatment, peanut-allergic patients are able to tolerate a defined amount of peanut protein with no more than mild allergic symptoms. Published ARC001 Phase 2 Results in Peer-Reviewed Journal. In October, Aimmune announced the publication of results from its Phase 2 ARC001 trial of AR101 in The Journal of Allergy and Clinical Immunology: In Practice 1. This was the first peer-reviewed publication of efficacy and safety of an industry-sponsored food allergy trial. The ARC001 study demonstrated that approximately six months of AR101 treatment significantly raised the level of tolerance of peanut protein, compared to placebo. The observed differences in response rate between AR101 and placebo groups on the Intent-to-Treat (ITT) analysis were 60 percent for the 300-mg endpoint (95% CI 34-87%) and 62 percent for the 600-mg endpoint (95% CI 37-87%). The lower bound of the 95% confidence interval on the ARC001 ITT analysis greatly exceeded the minimally clinically meaningful difference of 15 percent agreed to with the Food and Drug Administration (FDA) for the Phase 3 PALISADE study primary endpoint. Consistent with the known mechanisms of oral immunotherapy, transient allergic symptoms occurred in nearly all AR101 subjects, with 96 percent of those symptoms being mild, not dose-limiting, and not requiring medical intervention. No adverse events were graded as severe. Gastrointestinal symptoms were the most common treatment-related adverse events in both the AR101 and the placebo subjects.
Announced Publication of Clinical Data Demonstrating the Potential of AR101 to Reduce Peanut-Specific T H 2 Cells. In August, Aimmune announced that AR101 was featured in a publication by Benaroya Research Institute in the August 2 issue of Science Translational Medicine 2 focused on the discovery of an immune cell subset — T H2A cells - that appears to be involved in the pathogenesis of allergies. These allergen-specific T cells are present in people with allergies but nearly entirely absent from people without allergies.In a small pilot experiment, AR101 treatment was associated with a statistically significant reduction of T H2A cells in blood samples from a subset of peanut-allergic patients from Aimmune's ARC001 trial. Specifically, patients receiving AR101 experienced statistically significant reductions in T H2A cells, whereas there was no reduction in T H2A cells in patients receiving placebo. These T H2A cell reductions appeared to be associated with clinical response. Upcoming Milestones Completion of PALISADE Around Year-End 2017; Top-Line Data in First Quarter 2018. Aimmune expects that the last double-blind, placebo-controlled food challenge (DBPCFC) in its Phase 3 PALISADE trial of AR101 will be conducted in December 2017 and that top-line data will be available in the first quarter of 2018. There are two statistical analysis plans: one is designed to support a Biologics License Application (BLA) with the U.S. Food and Drug Administration (FDA), and the other to support a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA). The primary endpoint for the BLA is the proportion of subjects ages 4-17 who tolerate a single highest dose of at least 600 mg in the exit DBPCFC after six months of maintenance therapy. As part of the statistical analysis plan's requirements for success as agreed with the FDA, the study must demonstrate at least a 15 percent superiority margin of the AR101 arm over the placebo arm; the study is powered greater than 90 percent to detect this difference. Tolerating single highest doses of at least 300 mg and 1,000 mg are secondary endpoints for the BLA. The primary endpoint for the MAA is the proportion of subjects ages 4-17 who tolerate a single highest dose of at least 1,000 mg. There is no requirement to demonstrate a 15 percent margin of superiority for the MAA. Tolerating single highest doses of at least 300 mg and 600 mg are secondary endpoints for the MAA.
Third Quarter Financial ResultsFor the quarter and nine months ended September 30, 2017, net loss was $31.8 million and $90.2 million, respectively, compared to net loss of $22.1 million and $55.7 million for the comparable periods of 2016. On a per share basis, net loss for the quarter and nine months ended September 30, 2017, was $0.63 and $1.79, respectively, compared to net loss per share of $0.53 and $1.33 for the comparable periods of 2016. The weighted average shares outstanding for each of the quarter and nine months ended September 30, 2017 were 50.5 million and 50.3 million shares, respectively, compared to 42.0 million and 41.8 million shares for the comparable periods in 2016. Research and development expenses for the quarter and nine months ended September 30, 2017, were $21.1 million and $60.7 million, respectively, compared to $15.9 million and $37.7 million for the comparable periods in 2016. The increase was primarily due to the development of AR101, including progression of the PALISADE trial, enrollment of patients in the open-label follow-on study of PALISADE (ARC004) and the real-life RAMSES trial, and contract manufacturing costs. General and administrative expenses for the quarter and nine months ended September 30, 2017, were $11.2 million and $31.0 million, respectively, compared to $6.4 million and $18.5 million for the comparable periods in 2016. The increase was primarily due to additional employee-related costs, including stock-based compensation expense, and external professional services as Aimmune continues to build the infrastructure to support the development and potential commercialization of AR101. Cash, cash equivalents, and investments totaled $212.0 million at September 30, 2017, compared to $282.5 million at December 31, 2016. The decrease primarily reflects cash used in operations.
