Aridis Pharmaceuticals

Aridis Pharmaceuticals, Inc. is a late-stage biopharmaceutical company established in 2003, focusing on the development of novel anti-infective therapies. The company was co-founded by Vu L. Truong, Ph.D., and Eric J. Patzer, Ph.D. Dr. Truong, who serves as the CEO, brings over two decades of experience in biopharmaceutical drug development from roles at companies like Aviron and MedImmune, with a long-standing focus on developing human monoclonal antibodies (mAbs) for life-threatening infections. His work has been instrumental in creating Aridis' core technologies. Dr. Patzer, the Chairman of the Board, has a background that includes leadership positions at Genentech and Aviron, notably as the project leader for the FluMist™ intranasal influenza vaccine.

Aridis targets infectious diseases with significant unmet medical needs, particularly hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and infections affecting cystic fibrosis patients. The company's business model centers on discovering and advancing a pipeline of drug candidates, with revenue generation anticipated from partnerships, licensing agreements, and eventual product commercialization. A key component of its strategy involves utilizing proprietary technology platforms, such as MabIgX®, which facilitates the rapid identification of rare and potent antibodies from patients who have successfully recovered from an infection. This approach aims to create therapies that can be used as adjunctive treatments to the standard-of-care antibiotics.

The company's pipeline features several fully human monoclonal antibody candidates. The lead product, AR-301, is a mAb targeting the alpha-toxin produced by Staphylococcus aureus (S. aureus) and is in late-stage clinical development as a treatment for VAP. Another significant candidate is AR-320 (suvratoxumab), a Phase 3-ready mAb in-licensed from AstraZeneca, designed for the prevention of S. aureus pneumonia. The pipeline also includes AR-501, an inhaled formulation of gallium citrate for chronic lung infections in cystic fibrosis patients, and preclinical programs like AR-401 for infections caused by Acinetobacter baumannii. Recently, the company executed an asset acquisition agreement for AR-501 with an undisclosed partner, securing payments and future royalties.
