About CorMedix
CorMedix Inc. is a biopharmaceutical company focused on developing and commercializing therapeutic
products for the prevention and treatment of infectious and inflammatory diseases. The Company is
focused on developing its lead product Neutrolin®, a novel, non-antibiotic antimicrobial solution designed
to prevent costly and dangerous bloodstream infections associated with the use of central venous
catheters for the U.S. market. The Company completed a Phase 3 clinical trial of Neutrolin in patients
undergoing chronic hemodialysis, which showed a 71% reduction in catheter-related bloodstream
infections (CRBSIs) relative to the heparin control arm (p=0.0006) with a good safety profile. Such
infections cost the U.S. healthcare system approximately $6 billion annually and contribute significantly
to increased morbidity and mortality. Neutrolin has FDA Fast Track status and is designated as a Qualified
Infectious Disease Product, which provides the potential for priority review of a marketing application by
FDA and allows for 5 additional years of QIDP market exclusivity in the event of U.S. approval. FDA has
granted rolling submission and review of portions of the new drug application (NDA) and CorMedix has
begun submission of the NDA. Neutrolin is already marketed as a CE Marked product in Europe and other
territories. In parallel, CorMedix is leveraging its taurolidine technology to develop a pipeline of
antimicrobial medical devices, with active programs in surgical sutures and meshes, and topical hydrogels.
The company is also working with top-tier researchers to develop taurolidine-based therapies for rare
pediatric cancers. For more information, visit: www.cormedix.com.
