ASLAN Pharmaceuticals signs agreement with CSL to develop novel therapy for asthma

SINGAPORE and MELBOURNE, Australia I May 13, 2014 I ASLAN Pharmaceuticals Pte Ltd today announced a global license agreement to develop CSL Limited's (ASX:CSL) anti-IL13 receptor monoclonal antibody, CSL334, currently in preclinical development for the treatment of asthma.

Under the agreement, ASLAN will fund and develop CSL334 through to clinical proof of concept in a development program conducted primarily in Asia, targeting patients suffering moderate persistent to severe allergic asthma whose disease is not adequately controlled by existing treatments. Upon achievement of clinical proof of concept, ASLAN will identify a global partner for phase 3 development and commercialisation.

"Many patients with moderate and severe asthma still do not have their disease adequately controlled by current therapies, and these patients represent around half of the total burden of asthma worldwide," said Dr Mark McHale, ASLAN's Chief Operating Officer. "Some major companies are now pursuing strategies to help these patients, many of whom live in fear of their next serious exacerbation. As one of the leaders in the biologics industry, CSL have developed a unique approach to controlling the pathways responsible for this disease."

"The IL-13 receptor signalling pathway plays a critical role in allergic airway disease, and CSL has had an interest in inhibiting this target since it was first identified at the Walter and Eliza Hall Institute of Medical Research in Australia. This led CSL scientists to discover and optimise the monoclonal antibody inhibitor known as CSL334," commented Andrew Nash, CSL's Senior Vice President, Research. "ASLAN's focus on efficiently designing and executing innovative clinical strategies, combined with its teams experience in asthma drug development, make it the ideal partner for moving this therapy forwards."

CSL will be entitled to share returns generated by ASLAN from partnering the project. Further financial details were not disclosed.
