• The TRials with EblasaKimab in Atopic Dermatitis (TREK-AD) study has enrolled the final patient
• Topline results expected in early July 2023

SAN MATEO, Calif. and SINGAPORE, Feb. 24, 2023 (GLOBE NEWSWIRE) -- ASLAN Pharmaceuticals (“ASLAN”, Nasdaq: ASLN), a clinical-stage, immunology-focused biopharmaceutical company developing innovative treatments to transform the lives of patients, today announced that it has enrolled the final patient in TREK-AD, a Phase 2b dose-ranging clinical study of eblasakimab in adults with moderate-to-severe atopic dermatitis (AD). ASLAN expects to report topline data from this study in early July 2023.

The randomized, double-blind, placebo-controlled, dose-ranging clinical study, TREK-AD, was initiated in early 2022 to evaluate the efficacy and safety of eblasakimab in biologic naïve AD patients during a 16-week treatment period and a 12-week safety follow-up period. The study has enrolled patients from more than 80 sites across North America, Europe and Asia Pacific. The primary efficacy endpoint is the percentage change in Eczema Area Severity Index (EASI) score from baseline to week 16. Secondary efficacy endpoints include the proportion of patients achieving validated Investigator Global Assessment (vIGA) score of 0 (clear) or 1 (almost clear), proportion of patients with a 75% or greater reduction in EASI (EASI-75), proportion of patients achieving EASI-50 (50% or greater reduction) and EASI-90 (90% or greater reduction), and changes in peak pruritus scores.        

“We are pleased to have enrolled the final patient in the TREK-AD study and look forward to sharing topline results from this important study in early July 2023. The findings will provide greater clarity on eblasakimab’s differentiation and, combined with data from the ongoing TREK-DX study, will support its potential as a biologic of first-choice for AD patients,” said Dr Alex Kaoukhov, CMO, ASLAN Pharmaceuticals. “We are grateful to all patients, physicians, and trial investigators involved in the study. Their involvement is testament to the need that exists for new therapies to treat AD.”

About eblasakimab

Eblasakimab is a potential first-in-class monoclonal antibody targeting the IL-13 receptor subunit of the Type 2 receptor, a key pathway driving several allergic inflammatory diseases. Eblasakimab’s unique mechanism of action enables specific blockade of the Type 2 receptor and has the potential to improve upon current biologics used to treat allergic disease. By blocking the Type 2 receptor, eblasakimab prevents signaling through both interleukin 4 (IL-4) and interleukin 13 (IL-13) – the key drivers of inflammation in atopic dermatitis (AD). Positive results from a Phase 1b multiple-ascending-dose study established proof-of-concept for eblasakimab and supported its potential as a novel, differentiated treatment for AD. ASLAN is currently conducting TREK-AD, a Phase 2b trial to evaluate eblasakimab in biologic naïve moderate-to-severe AD patients, with topline readout expected in early July 2023. ASLAN is also investigating eblasakimab in dupilumab experienced, moderate-to-severe AD patients in the Phase 2 trial TREK-DX, with data expected in the first quarter of 2024.

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. Eblasakimab is being investigated in the global Phase 2b TREK-AD trial of moderate-to-severe AD patients and the Phase 2 TREK-DX trial in dupilumab-experienced AD patients. ASLAN is also developing farudodstat, a potent next-generation oral inhibitor of the enzyme DHODH, and plans to initiate a Phase 2 trial in an autoimmune skin disease in the first half of 2023. ASLAN has teams in San Mateo, California, and in Singapore.
