Our successful IPO on Euronext Brussels has significantly strengthened our financial position and we are well positioned to generate important data for our lead therapeutic antibody candidates. Our clinical stage programs, ARGX-110 and ARGX-111, are on track and we are pleased with the initial safety and biological activity data observed for ARGX-110 and our recent clinical development partnership with LLS. We were delighted to expand our successful collaboration with Shire for the second time and to have signed new collaborations with Bayer and Boehringer Ingelheim to leverage the power of our SIMPLE Antibody™ platform against multiple, complex targets across a range of indications. We remain focused on executing our well thought out strategy, which we believe will deliver significant value for all of our stakeholders.
