Neal Walker
Analyst · Leerink. Your line is open
Thank you, Kamil. Hello, everyone, and thanks for joining us today. I will start with an update of our clinical development programs and other business highlights, then I will hand it off to Brett Fair, our Head of Commercial, who’ll then briefly address our pre-commercial planning activities after which Frank Ruffo, our CFO will review our financial results and 2017 guidance. After our prepared remarks, we’ll open up the line to take your questions. Chris Powala, our Chief Operating Officer; and Dr. Stuart Shanler, our Chief Scientific Officer will also be available during the question-and-answer portion of the call. 2016 was a transformative year for Aclaris. During the year, we made significant progress on all of our programs, enabling us to enter 2017 with a solid foundation and continued momentum as we head towards the goal of becoming a fully integrated biotechnology company. Let me recap several of the key milestones from 2016 starting with each of our three clinical programs. First, at the start of 2016, we initiated the Phase 3 clinical program for A-101 40% Topical Solution for the treatment of SKs. As a reminder, A-101 is being positioned to the cash-paid minimally invasive procedure that will be performed in the physicians’ office. The Phase 3 clinical program consisted of two randomized, double-blind, vehicle-controlled trials known as SEBK-301 and SEBK-302 and an open-label safety study known as SEBK-303. Patients in 301 and 302 received up to two treatments of A-101 40% during the course of the trial. The three trials enrolled a total of almost 1,100 patients across 44 centers in the U.S. In November, we reported positive top line results from both Phase 3 trials. A-101 achieves statistically significant and clinically meaningful results on all primary and secondary endpoints. A-101 40% was also well tolerated. There were no treatment-related serious adverse events in the rates of hypopigmentation, hyperpigmentation, and scarring classified as greater than mild were less than 1% in all groups. Last month, we submitted a new drug application, or NDA to the FDA for seborrheic keratosis. We have planned for a 12-month review and are hopeful that we will receive approval in the U.S. in early 2018. In addition, we plan to file in the European Union in the second-half of 2017. Moving on to common warts. As a reminder, WART-201 was a randomized, double-blind, vehicle-controlled Phase 2 clinical trial designed to evaluate the safety and dose response of two concentrations of A-101 Topical Solution, 40% and 45%, compared with vehicle in patients with common warts. 98 patients were enrolled and patients received treatment once a week for eight weeks. In August, we reported the top line results of the WART-201 trial, in which A-101 45% achieves statistically significant and clinically meaningful results on all primary and secondary endpoints. A-101 45% was also well-tolerated. The local skin reactions were similar to placebo and most frequently reported local skin reactions across the treatment groups was mild erythema. In addition, we also followed the patients for three months post the last treatment to assess durability. In the 45% group, only one wart recurred, demonstrating a durable response with this treatment. Given the safety and efficacy demonstrated in this Phase 2 trial and following an FDA guidance telecon, we intend to develop A-101 45% solution for common warts and plan to initiate Phase 2b trials later this year. In the Phase 2b program, we intend to have the patients apply the drug and will position the product as a prescription meant for at home use. This brings us now to our Janus Kinase or JAK inhibitor portfolio with which we are targeting multiple dermatologic diseases, including alopecia areata, vitiligo and androgenetic alopecia. Late last year, we submitted an investigational new drug application, or IND and began a Phase 1 human pharmacokinetic/pharmacodynamic trial for ATI-50001, the oral formulation of our JAK 1/3 inhibitor. We expect data from this trial in the coming weeks and are planning to initiate a Phase 2 dose ranging trial in patients with the most severe forms of alopecia areata, alopecia totalis, and universalis in the second-half of this year. For ATI-50002, a topical formulation of a JAK 1/3 inhibitor, we plan to initiate a Phase 2 dose ranging trial in patients with the patchy form of alopecia areata in the second-half of this year as well. In addition to advancing our JAK inhibitor program for the treatment of alopecia areata, as we reported on our last call, we have initiated preclinical development of additional JAK inhibitors, which we’re developing for topical use, both in vitiligo and androgenetic alopecia. We also plan to initiate a clinical trial with the topical JAK inhibitor in vitiligo in the second part of this year. As a reminder, in addition to our portfolio of JAK inhibitors, our intellectual property portfolio includes method of use IP directed towards the use of JAK inhibitors in a variety of hair loss disorders. We have initiated U.S. patent directed to methods of treating alopecia areata, androgenetic alopecia, and other hair loss disorders by administering ruxolitinib, and a recently issued patent in Japan directed to pharmaceutical compositions comprising ruxolitinib, baricitinib, or other JAK inhibitors for use in treating alopecia areata, androgenetic alopecia, and other hair loss disorders. We look forward to keeping you updated on additional progress during the course of the year. Now, I would like to turn the call over to Brett Fair, our Head of Commercial to discuss the pre- commercial activities of the past year. Brett?
