• In a preliminary review of blinded data from the ongoing TREK-DX study, 45% (10/22) of patients achieved at least a 90% reduction in their EASI score (EASI-90) after 16 weeks. 56% (5/9) of patients with prior inadequate response to dupilumab achieved EASI-90 and 56% (5/9) of patients achieved a vIGA score of 0 or 1 (clear or almost clear skin) after 16 weeks. Topline, unblinded data from the full dataset expected at the end of 2024.
• Phase 2 proof-of-concept trial of farudodstat in alopecia areata (the FAST-AA study) has recruited close to 75% of patients; topline data readout expected in Q3 2024. Positive opinion received from European Patent Office on new patent application of farudodstat with potential to extend protection until at least 2043.

SAN MATEO, Calif. and SINGAPORE, April 12, 2024 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals (Nasdaq: ASLN), a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided an update on recent corporate activities.

“2023 marked a significant year for ASLAN, most notably because of the announcement of positive topline results from the TREK-AD Phase 2b study of eblasakimab in patients with moderate-to-severe atopic dermatitis (AD), and also a number of other advancements across our clinical pipeline. We initiated the FAST-AA clinical study of farudodstat in alopecia areata, and generated compelling translational data on eblasakimab that demonstrated the differentiated effects of targeting IL-13R versus IL-4R in the treatment of AD and supports the potential of eblasakimab as a biologic therapy for COPD,” said Dr Carl Firth, CEO, ASLAN Pharmaceuticals. “The blinded data we recently disclosed from the ongoing TREK-DX study of eblasakimab in dupilumab-experienced AD patients supports the potential of eblasakimab to treat AD patients that do not achieve an optimal response to dupilumab, a significant and underserved population with limited safe and long-term alternative treatment options. We look forward to the topline readout of the full, unblinded dataset from TREK-DX and the topline interim data from the FAST-AA study later this year.”

Fourth quarter 2023 and recent business highlights

Q4 and recent clinical developments

• In October 2023, positive topline data from TREK-AD Phase 2b study of eblasakimab in moderate-to-severe AD presented in late-breaker oral presentation. New data from the Phase 2b TREK-AD study of eblasakimab for the treatment of moderate-to-severe AD was presented in a late-breaking oral presentation at the 32nd Annual European Congress of Dermatology and Venereology.
• In October 2023, hosted a key opinion leader (KOL) event on the changes in the clinical trial and treatment landscape in AD. ASLAN co-hosted an investor event with a leading Clinical Research Organization and KOLs, Jonathan Silverberg, MD PhD MPH (The George Washington University School of Medicine and Health Sciences), and April W. Armstrong, MD MPH (UCLA). In new analyses of more severe patients (baseline EASI 18 or higher) from the TREK-AD study presented at the event, 55.6% of patients treated with 600mg eblasakimab once every 4 weeks saw at least a 75% reduction in their EASI score (EASI-75) versus 15.4% of patients on placebo, and 30.6% of patients achieved a validated Investigator Global Assessment (vIGA) score of 0 or 1 (clear or almost clear skin) versus 8.0% on placebo. A replay is available here.
• In November 2023, data presented in an indication beyond AD for eblasakimab for the first time. At the Dermatology Drug Development Summit, ASLAN demonstrated the potential utility of eblasakimab in an indication beyond AD via a human translational model of chronic obstructive pulmonary disease (COPD). The data showed that eblasakimab was effective in reducing IL-4 and IL-13 driven airway hyperresponsiveness.
• In December 2023, blinded safety data from the ongoing Phase 2a FAST-AA study of farudodstat in alopecia areata (AA) was disclosed. The data showed no liver or other major safety concerns to date in patients enrolled, supporting farudodstat’s improved safety profile compared to the first-generation of approved dihydroorotate dehydrogenase (DHODH) inhibitors. Farudodstat, a highly selective, oral DHODH inhibitor, has the potential to be a first-in-class treatment for AA. The FAST-AA study has now recruited close to 75% of patients and topline interim data from the study is expected to be available in Q3 2024.
• In February 2024, received a favorable opinion from the European Patent Office (EPO) on composition of matter patent application for farudodstat. The EPO is acting as the International Examiner on a polymorph patent application for farudodstat, which, if granted in the national stages, will extend effective patent protection for farudodstat until at least 2043.
• In March 2024, announced positive translational data from a head-to-head study of eblasakimab versus dupilumab in a human tissue model of COPD. In the study, eblasakimab performed better than dupilumab in improving airway function and enhancing bronchodilation at the same concentrations, providing further support for the potential of eblasakimab as a biologic therapy for COPD. The data has been submitted for presentation at an upcoming scientific conference.
• In March 2024, announced preliminary blinded data from the TREK-DX study. In a review of data from 22 patients treated in the TREK-DX study, 45% (10/22) of patients saw at least a 90% reduction in their EASI score (EASI-90) and 50% (11/22) of patients achieved a vIGA score of 0 or 1 after 16 weeks. Of the 9 patients who previously had an inadequate response to dupilumab, 5 patients (56%) achieved EASI-90 and 5 patients (56%) a vIGA score of 0 or 1. TREK-DX is the first and only randomized, double-blind, placebo-controlled study to be conducted in a dupilumab-experienced AD patient population. Topline unblinded data from the full dataset is expected at the end of 2024.
  

Corporate updates

• In December 2023, ASLAN amended the terms of its loan agreement with K2 HealthVentures. In order to substantially reduce the total payments due to K2 HealthVentures during 2024 and extend the date from which the Company is required to make monthly repayments to January 2025, ASLAN made a prepayment of $12.0 million which was applied to the outstanding principal under the loan agreement. $13.0 million of principal now remains outstanding under the loan agreement. The prepayment allowed the Company to reduce total cash burn for 2024.
• In March 2024, in line with evaluating the potential use of eblasakimab as a therapy to treat COPD, ASLAN appointed respiratory experts Dr Ramaswamy Krishnan, MS MPhil PhD, Associate Professor in Emergency Medicine, Harvard Medical School, and Dr Reynold Panettieri, Jr, MD, Vice Chancellor, Translational Medicine and Science, Rutgers University to ASLAN’s Scientific Advisory Board.
• In March 2024, ASLAN completed a $5.0 million registered direct offering for the purchase and sale of 5,000,000 of the Company’s American Depositary Shares (“ADSs”), each ADS representing twenty-five (25) ordinary shares, at an offering price of $1.00 per ADS. In addition, in a concurrent private placement, the Company issued unregistered warrants to purchase up to 5,000,000 ADSs with an exercise price of $1.00 per ADS.
  

Anticipated upcoming milestones

• Presentation of positive translational data from a head-to-head study of eblasakimab versus dupilumab in a human tissue model of COPD at an upcoming scientific congress in Q2 2024
