About KL-00119:  KL-00119 is an alginate-based oral trans-mucosal film.  KL-00119 is the first oral trans-mucosal migraine product and is designed to be a significant improvement to all available acute migraine treatments available to patients today, particularly in patients suffering from migraine-induced nausea and vomiting.   KL-00119 is also particularly suited for the treatment of migraine in pediatric populations.   KL-00119 is a unique molecular dispersion of the active antimigraine drug sumatriptan.  The KL-00119 film presents sumatriptan to the oral mucosal surface in a unique way to allow rapid, consistent absorption with the lowest possible burden on the patient.  The base film-forming alginate and the sumatriptan-containing films have been the subject of comprehensive intellectual property protection, thus ensuring prolonged market exclusivity.  The uniqueness and promise of the KL-00119 has been confirmed by the project being awarded the exclusive European Commission Horizon 2020 Innovation Grant in 2018 (Grant Number 8296159).
