ASLAN Pharmaceuticals Reports Third Quarter 2023 Financial Results and Provides Corporate Update

• Positive topline data reported in July from TREK-AD, a Phase 2b study of eblasakimab in moderate-to-severe atopic dermatitis, met the primary endpoint across three dosing arms; the study established eblasakimab’s potential to deliver a monthly dosing regimen from initiation with a competitive efficacy profile.
• Preparations underway for the advancement of eblasakimab into Phase 3 clinical development in 2024.
• Topline interim data from the FAST-AA (FArudodstat STudy in Alopecia Areata) Phase 2a study of farudodstat expected in the first quarter of 2024.
• $40.8 million in cash and cash equivalents as of September 30, 2023; expected runway into the second half of 2024.

SAN MATEO, Calif. and SINGAPORE, Oct. 27, 2023 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals Pte Ltd (Nasdaq: ASLN), a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients, today announced financial results for the third quarter ended September 30, 2023, and provided an update on recent corporate activities.

“At the start of the third quarter, we presented positive topline Phase 2b data from the TREK-AD study showing eblasakimab has the potential to deliver a monthly dosing regimen from initiation of treatment with a competitive efficacy profile. In our recent survey of US physicians, this attribute was considered to be one of the most important in a new therapy for atopic dermatitis (AD) and a compelling advantage to differentiate eblasakimab within the current AD treatment landscape by seventy percent of those surveyed,” said Dr Carl Firth, CEO, ASLAN Pharmaceuticals.

“Additionally, data from the TREK-AD study was accepted as a late-breaker oral presentation at the European Academy of Dermatology and Venereology congress in October. We presented a new analysis demonstrating eblasakimab was equally effective in AD patients whose disease was scored as severe, while placebo effects were markedly reduced, leading to a widening in placebo-adjusted efficacy. The correlation of high placebo rates with lower disease severity has been observed in other recent AD studies and highlights the sensitivity of the placebo response to disease severity. As discussed in a recent webinar we hosted with key opinion leaders in dermatology, the absolute efficacy of a drug could be a more reliable measure, and more relevant in the real world, than placebo-adjusted efficacy where there are differences in baseline disease severity. These analyses and others still ongoing, together with the findings from our patient and physician surveys, support our planning of a Phase 3 study of eblasakimab, which we would expect to initiate in 2024 alongside a global commercial partner,” Dr Firth added.

Third quarter 2023 and recent business highlights

Q3 and recent clinical developments

• In July, ASLAN published a perspective article in Annals of Allergy, Asthma and Immunology, in collaboration with Emma Guttmann-Yassky MD, PhD, titled “Targeting type 2 immune activation beyond atopic dermatitis”. The article discusses the potential of a therapeutic like eblasakimab to treat a range of Type 2 driven comorbidities beyond AD. The open access article can be read here.
• In July, ASLAN presented five abstracts showcasing findings related to eblasakimab as posters and oral presentations at the 25^th World Congress of Dermatology which took place in Singapore. The posters can be accessed in the “Publications” section of ASLAN’s website.
• In July, ASLAN announced positive topline data from the Phase 2b dose-ranging TREK-AD study of eblasakimab that met the primary endpoint across three dose arms. Eblasakimab demonstrated the potential for once-monthly dosing from initiation with a competitive efficacy profile in moderate-to-severe AD.
• In October, ASLAN presented a late-breaker abstract showcasing new data from the TREK-AD study of eblasakimab at the 32^nd EADV Congress, in Berlin, Germany. New data from a post-hoc analysis of patients with severe disease (defined as those with a baseline Eczema Area and Severity Index (EASI) score of at least 21), representing 63% of the intent-to-treat patients, show monthly dosing with 600 mg eblasakimab for 16 weeks led to a 74.5% reduction in EASI score (versus 38.0% on placebo, p<0.0001) and EASI-75 of 53.6% (versus 12.9% on placebo, p=0.0009), representing a marked widening in placebo-adjusted efficacy while the response to eblasakimab treatment was maintained. Three additional abstracts on eblasakimab and farudodstat were presented at the congress. The posters can be accessed in the “Publications” section of ASLAN’s website.
• In October, in collaboration with Dermatology Times, ASLAN published a virtual KOL video series featuring Dr Peter Lio, MD, FAAD showcasing insights from a survey commissioned by ASLAN on US patients’ satisfaction with current AD treatments and physician prescribing habits. The video series can be accessed here.
• In October, ASLAN co-hosted a panel discussion with a leading Clinical Research Organization entitled, “The Changing Face of Atopic Dermatitis: How the Clinical Trial and Treatment Landscape has Changed in the Seven Years Following Dupilumab’s Introduction” that featured Key Opinion Leaders, Jonathan Silverberg, MD, PhD, MPH (The George Washington University School of Medicine and Healthy Sciences) and April W. Armstrong, MD, MPH (UCLA). ASLAN presented further post-hoc analyses from the TREK-AD study, as well as insights from a recently completed survey of AD patients and US physicians’ attitudes to prescribing treatments for AD. A replay of the event is available here.

Anticipated upcoming milestones

• Presentation of preliminary results on eblasakimab in a human translational model of chronic obstructive pulmonary disorder (COPD) at the 7^th Annual Dermatology Drug Development Summit for Inflammatory Skin Diseases on 2 November.
• Topline interim data from the FAST-AA study of farudodstat is expected in the first quarter of 2024.
• A Phase 1 trial of eblasakimab in Japan is expected to be initiated by ASLAN’s partner, Zenyaku Kogyo Co,. in the first half of 2024.
• ASLAN is conducting continued analyses of the TREK-AD study and plans to submit data on biomarkers and patient reported outcomes for publication at a future scientific congress.
• An end-of-Phase 2 meeting with the US Food and Drug Administration is expected and subsequent initiation of the Phase 3 clinical program for eblasakimab is expected to occur in 2024.

Third quarter 2023 financial highlights

• As of September 30, 2023, the Company had cash and cash equivalents of $40.8 million.
• Cash used in operations for the third quarter of 2023 was $13.7 million compared to $9.1 million in the same period in 2022. Net cash outflow was $1.7M following receipt of $12.0 million in July from Zenyaku Kogyo Co. as an upfront strategic license payment.
• Research and development expenses were $7.2 million in the third quarter of 2023 compared to $8.0 million in the third quarter of 2022. The decrease was due to lower clinical development and manufacturing costs for the eblasakimab studies following the TREK-AD topline data readout.
• General and administrative expenses were $3.2 million in the third quarter of 2023 compared to $2.3 million in the third quarter of 2022.
