ATI-502

→ Zymeworks used a poison pill maneuver a couple weeks ago as the counterpunch to a $773 million takeover bid by All Blue Falcons , and new CEO Kenneth Galbraith isn’t done piecing the staff together either. Paul Moore will end his 14-year association with MacroGenics , where he was VP, cell biology, and immunology, and step up to the plate as CSO of Zymeworks on July 18. Tony Polverino , the chief scientist who preceded Moore, didn’t escape the sweeping changes that were enacted by Galbraith in January, when half the C-suite and 25% of the staff overall received pink slips.

Positive Preliminary Topline Data for ATI-450, an Investigational Oral MK2 Inhibitor, in Moderate to Severe Rheumatoid Arthritis Announced in January 2021 ATI-450 Data Support New Oral Approach for the Potential Treatment of Immuno-inflammatory Diseases, such as Rheumatoid Arthritis Public Offering of $103.5M in January 2021 Strengthens Balance Sheet WAYNE, Pa., Feb. 25, 2021 (GLOBE NEWSWIRE) -- Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a clinical-stage biopharmaceutical company focused on developing novel drug candidates for immuno-inflammatory diseases, today announced its financial results for the fourth quarter and full year of 2020 and provided a corporate update. “As we reflect on 2020, we are proud of how we have progressed our immuno-inflammatory development programs,” said Dr. Neal Walker, President & CEO of Aclaris. “We are very excited about the platform potential of ATI-450, an oral MK2 inhibitor which we have shown to inhibit TNFα, IL1β, and IL6. Given its novel mechanism, there are several immuno-inflammatory indications that ATI-450 may potentially address. We are also excited about the potential of our pipeline which is internally generated from KINect®, our proprietary drug discovery platform, for various immuno-inflammatory indications. We look forward to building on this momentum in 2021.” Research and Development Highlights: The global COVID-19 pandemic continues to rapidly evolve and has caused and may continue to cause Aclaris to experience disruptions that could impact the timing of its research and development and regulatory activities listed below. ATI-450 , an investigational oral small molecule MK2 inhibitor compound: ATI-450-RA-201 : A Phase 2a, multicenter, randomized, investigator and patient-blind, sponsor-unblinded, parallel group, placebo-controlled clinical trial to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of ATI-450 in subjects with moderate to severe rheumatoid arthritis. Positive preliminary topline data announced in January 2021. In this trial, ATI-450 demonstrated durable clinical activity, as defined by a marked and sustained reduction in DAS28-CRP and improvement of ACR20/50/70 responses over 12 weeks. This clinical activity was further supported by pharmacodynamic analyses showing a marked and durable inhibition of TNFα, IL1β, IL6, and IL8 in ex vivo stimulated samples as well as an endogenous inflammation biomarker analysis which also demonstrated a marked and sustained inhibition of median concentrations of hsCRP, TNFα, IL6, IL8, and MIP1β in the treatment arm over the 12 week period. ATI-450 was generally well tolerated. The most common adverse events (AE) (each reported in 2 subjects) were urinary tract infection (UTI), elevated lipids and ventricular extrasystoles, all of which were determined to be unrelated to treatment except for one UTI. There was one non-treatment-related serious adverse event (COVID-19) reported in the four-week safety follow-up phase of the trial in a subject who was no longer receiving treatment. Aclaris intends to progress ATI-450 into a Phase 2b trial in moderate to severe rheumatoid arthritis in the second half of 2021. Aclaris is currently evaluating additional potential indications driven by TNFα, IL1β and IL6 as part of its planned expansion of its Phase 2 immuno-inflammatory clinical development programs. ATI-450-PKPD-102 : A Phase 1, placebo-controlled, randomized, observer-blind clinical trial to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ATI-450 at 80 mg and 120mg twice daily in health subjects. Positive preliminary topline data announced in January 2021. Pharmacodynamic analysis demonstrated incremental cytokine suppression at these higher doses. ATI-450 was generally well tolerated. The most common AEs (reported by 2 or more subjects who received ATI-450) were headache, dizziness, nausea, parasthesia and, in the post-dosing safety follow-up phase of the trial, dry skin. These AEs were all mild in severity. A final analysis of this trial is underway. ATI-450-CAPS-201 : A Phase 2a, multicenter, open-label, single-arm clinical trial to investigate the safety, tolerability, efficacy and pharmacodynamics of ATI-450 for the maintenance of remission in subjects with cryopyrin-associated periodic syndrome (CAPS) previously managed with anti-IL1 therapy. Due to the COVID-19 pandemic, subject enrollment in this trial was paused. As a result of the ongoing pandemic and given the positive preliminary topline data from the ATI-450-RA-201 trial, Aclaris has decided to focus its efforts and resources on other immuno-inflammatory diseases. , an investigational oral small molecule MK2 inhibitor compound: ATI-1777 , an investigational topical “soft” Janus Kinase (JAK) 1/3 inhibitor compound: ATI-1777-AD-201 : An ongoing Phase 2a, multicenter, randomized, double-blind, vehicle-controlled, parallel-group clinical trial to investigate the efficacy, safety, tolerability and pharmacokinetics of ATI-1777 in subjects with moderate to severe atopic dermatitis. The primary endpoint is the percentage change from baseline in the Eczema Area and Severity Index (EASI) score at week 4. Data from this trial are expected mid-year 2021. , an investigational topical “soft” Janus Kinase (JAK) 1/3 inhibitor compound: ATI-2138 , an investigational oral ITK/TXK/JAK3 (ITJ) inhibitor compound: Aclaris is developing ATI-2138 as a potential treatment for T-cell mediated diseases such as psoriasis and/or inflammatory bowel disease and expects to submit an Investigational New Drug Application for ATI-2138 in the second half of 2021. , an investigational oral ITK/TXK/JAK3 (ITJ) inhibitor compound: Financial Highlights: Liquidity and Capital Resources As of December 31, 2020, Aclaris had aggregate cash, cash equivalents, restricted cash and marketable securities of $54.1 million compared to $75.0 million as of December 31, 2019. The changes in cash and cash equivalents and marketable securities during the year included: Net cash used in operating activities was $38.6 million resulting from net loss of $51.0 million and changes in operating assets and liabilities of $2.4 million, partially offset by non-cash adjustments of $14.7 million. Net borrowings of $10.9 million pursuant to a Loan and Security Agreement. Net proceeds of $7.7 million from the sale of 2.1 million shares of common stock under an equity line of credit agreement. In January 2021, Aclaris closed a public offering in which it sold approximately 6.3 million shares of common stock. Proceeds from the offering were $103.5 million, net of underwriting discounts, commissions and offering expenses. Aclaris anticipates that its cash, cash equivalents and marketable securities as of December 31, 2020 in combination with the proceeds from the January 2021 public offering will be sufficient to fund its operations through the end of 2023, without giving effect to any potential business development transactions or financing activities. Financial Results Fourth Quarter 2020 Net loss was $13.2 million for the fourth quarter of 2020 compared to $18.6 million for the fourth quarter of 2019.

Research and development (R&D) expenses were $9.0 million for the quarter ended December 31, 2020 compared to $11.5 million for the prior year period. The quarter-over-quarter decrease of $2.6 million was primarily the result of expenses related to Aclaris’ legacy JAK inhibitors ATI-501 and ATI-502, including the substantial completion of Aclaris’ various Phase 2 clinical trials, and the substantial completion of two pivotal Phase 3 clinical trials of A-101 45% Topical Solution in 2019. General and administrative (G&A) expenses were $4.9 million for the quarter ended December 31, 2020 compared to $5.8 million for the prior year period. The quarter-over-quarter decrease of $0.9 million was primarily the result of lower non-cash stock-based compensation expense resulting from headcount reductions. Stock-based compensation expense was $1.6 million compared to $2.6 million in the prior year period. Full Year 2020 Net loss was $51.0 million for the year ended December 31, 2020 compared to $161.4 million for the year ended December 31, 2019.

R&D expenses in 2020 included non-cash stock-based compensation expense of $2.9 million compared to $5.1 million in the prior year period. G&A expenses were $20.5 million for the year ended December 31, 2020 compared to $27.8 million for the prior year period. The decrease of $7.3 million was primarily the result of lower personnel and non-cash stock-based compensation resulting from headcount reductions. G&A expenses in 2020 included non-cash stock-based compensation expense of $7.3 million compared to $10.3 million in the prior year period. For the year ended December 31, 2019, there was also a $18.5 million non-cash charge for the impairment of goodwill. About Aclaris Therapeutics, Inc.
