ASLAN announces the completion of enrolment in second cohort and the opening of new sites in US and Australia in ASLAN004 atopic dermatitis study

On September 21, 2020, ASLAN Pharmaceuticals Limited (the Company) issued a press release announcing that clinical sites in the United States (US) and Australia are now open and ready to enroll patients into its multiple ascending dose (MAD) study testing the first-in-class therapeutic antibody ASLAN004 in moderate to severe atopic dermatitis (AD) patients. Patients will now be recruited from four sites in Australia and three sites in the US, alongside two existing sites in Singapore.

The Company recently restarted recruitment into the second cohort of the randomized, double blind, placebo-controlled study in Singapore following the lifting of government restrictions in response to COVID-19. All eight patients have now been fully recruited into the cohort and the Company plans to initiate recruitment into the third cohort following approval by the Data Monitoring Committee. A further eight patients will be recruited in Singapore, the US and Australia. The Company expects to report interim, unblinded data from all three dose cohorts in 4Q 2020.

ASLAN004 is a first-in-class monoclonal antibody that binds to the IL-13 receptor α1 subunit (IL-13Rα1), blocking signaling of two pro-inflammatory cytokines, IL-4 and IL-13, which are central to triggering symptoms of AD, such as redness and itching of the skin.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
