Announcement ofthe temporary pause in the recruitment of new patients into ASLAN004 study due to COVID-19

On April 13, 2020, ASLAN Pharmaceuticals Limited issued a press release announcing that recruitment of new patients into its randomised, double-blind, placebo-controlled multiple ascending dose (MAD) study of ASLAN004 in moderate to severe atopic dermatitis has been paused in light of recently imposed government restrictions in Singapore to contain the spread of the coronavirus disease (COVID-19). ASLAN does not currently expect these measures to materially affect the projected timelines for the readout of interim, unblinded data later this year.

ASLAN intends to resume screening as soon as government restrictions are lifted and is taking steps to open sites in Australia to accelerate recruitment. The study remains on track to report interim, unblinded data from all 3 dose cohorts in MAD study in 3Q 2020.

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