LEO Pharma and JW Pharmaceutical Corporation announced that LEO Pharma has filed an Investigational New Drug Application (IND) to the US Food and Drug Administration (FDA) for a pharmacokinetics study in the US. The filing is based on the two companies’ ongoing collaboration on the development of JW1601/LP0190, an oral treatment for atopic dermatitis for which JW Pharmaceutical out-licensed their investigatory drug to LEO Pharma in August 2018. JW Pharmaceutical has since January this year conducted phase 1 clinical trial consisting of a single dose and repeated dose studies in healthy adults. Recently the single dose phase for Koreans was successfully completed with acceptable safety and tolerability observed up to the highest dose, 5th cohort. Based on this trial LEO Pharma has now filed a protocol for a pharmacokinetics study in US – a small clinical trial with healthy volunteers to further evaluate the pharmacokinetics of JW016/LP0190.
