ASLAN Pharmaceuticals Presents New Data on Eblasakimab in Atopic Dermatitis and COPD Translational Models at the 7th Dermatology Drug Development Summit
SAN MATEO, Calif. and SINGAPORE, Nov. 03, 2023 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals (Nasdaq: ASLN), a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients, today announced new data was presented at the Dermatology Drug Development Summit (DDDS) that took place in Boston, MA, from October 31 to November 2, 2023. The datasets presented strengthen evidence for eblasakimab’s differentiated mechanism of action in atopic dermatitis (AD), and, for the first time, show application in a new indication, chronic obstructive pulmonary disease (COPD), which can be driven by Type 2 inflammation.
A head-to-head study between eblasakimab and dupilumab conducted in skin punch biopsies of AD patients showed differential expression of inflammatory cytokines secreted by the localized skin tissue, with eblasakimab treatment more efficiently reducing expression of Th2 cytokines IL-13, IL-4 and sCD40L, as well as IL-17F and chemokines CCL3 and CCL4, compared to dupilumab treatment. These preliminary results validate previously published data1 from AD patient peripheral blood mononuclear cells from ASLAN’s research collaboration with Dr Shawn Kwatra (Johns Hopkins Medicine) and Dr Madan Kwatra (Duke University). These data together demonstrate eblasakimab’s differentiated effects compared to dupilumab and highlight the potential advantages to targeting IL-13R with eblasakimab, which may lead to more efficient blockade of Type 2 signaling while also sparing the Type 1 receptor.
ASLAN also presented new data investigating the role of eblasakimab in COPD using an established ex vivo model of precision cut lung slices from human donors2. The model tested airway hyperresponsiveness (AHR) in the lung tissue using IL-4 and IL-13, the key Th2 cytokines involved in COPD disease pathology3. Eblasakimab significantly reduced IL-4 and IL-13-induced AHR by reducing airway constriction. Furthermore, IL-4 and IL-13 sensitized the airways to further constriction in response to methacholine, but this sensitization was blocked by eblasakimab treatment. To examine the effects on airway dilation, formoterol was used to induce bronchodilation. IL-4 and IL-13 pre-treatment significantly decreased dilation in response to formoterol within 5 minutes of treatment, but these effects were effectively reversed by eblasakimab, restoring the airway’s normal response. Hence, eblasakimab successfully blocked IL-4/IL-13 induced AHR in lung tissue and restored the normal response of airway constriction and dilation which are of clinical significance in COPD. Eblasakimab blocks both IL-4 and IL-13 through the Type 2 receptor, giving it the potential to be more effective in a broader range of indications compared to drugs that only target the IL-13 cytokine.
“COPD is the third most common cause of mortality globally4 and is a heterogeneous disease with a significant proportion of patients affected by Type 2-driven pathology that have a limited range of targeted treatment options. The data we have presented in the translational models are key to exploring the potential of eblasakimab in other indications beyond AD, and we believe that there is great potential for eblasakimab to provide an effective and differentiated treatment option for COPD, a market that is expected to be $30 billion by 20325,” said Dr Carl Firth, Chief Executive Officer at ASLAN Pharmaceuticals. “While eblasakimab has already demonstrated a monthly dosing regimen in AD without compromising on efficacy, there is a vast unexplored potential in other diseases driven by the common underlying biology of Type 2 inflammation.”
“The translational data we have presented provide evidence of eblasakimab’s unique mechanism of action and highlight its differentiation from drugs targeting the IL-4R,” said Dr Ferda Cevikbas, Head, Translational Science at ASLAN Pharmaceuticals. “We are grateful for the invitation to present these translational models at this industry conference and showcase eblasakimab’s potential to address Type 2-driven inflammation across AD and COPD.”
Studies in both translational models are ongoing and ALSAN plans to submit comprehensive data sets for publication to upcoming scientific meetings. The presentation from Drug Development Summit can be accessed via the ASLAN website here.
About ASLAN Pharmaceuticals
ASLAN Pharmaceuticals (Nasdaq: ASLN) is a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients. ASLAN is developing eblasakimab, a potential first-in-class antibody targeting the IL-13 receptor in moderate-to-severe atopic dermatitis (AD) with the potential to improve upon current biologics used to treat allergic disease, and has recently reported positive topline data from a Phase 2b dose ranging study in moderate-to-severe AD. ASLAN is also developing farudodstat, a potent oral inhibitor of the enzyme dihydroorotate dehydrogenase (DHODH) as a potential first-in-class treatment for alopecia areata (AA) in a Phase 2a proof-of-concept trial with an interim readout expected in 1Q 2024. ASLAN has teams in San Mateo, California, and in Singapore. For additional information please visit the website or follow ASLAN on LinkedIn.
