We are a clinical stage biopharmaceutical company applying our pioneering DARPin® product candidates to treat serious diseases, with a current focus on infectious disease, oncology and ophthalmology. Our DARPin platform, which is designed using ankyrin repeat proteins, allows us to build product candidates with multiple mechanisms of action to address complex biological problems, while potentially offering patients products with higher efficacy and fewer adverse events. We believe that DARPin therapeutics represent a novel class of drugs with broad therapeutic applications that may overcome many of the limitations of conventional protein and antibody-based therapeutics. Our DARPin product candidates have been extensively tested in preclinical studies and clinical trials, including in approximately 2,000 patients in ophthalmology, infectious disease (SARS-CoV-2) and oncology, and have been observed to be highly active, present differentiated product profiles and be generally well-tolerated.

Our in-house DARPin programs are initially focused on infectious diseases, where we see potential in our first COVID-19 antiviral therapeutic product candidates in partnership with Novartis, and on our oncology program, where we see potential in the utility and flexibility of our DARPin molecules to offer differentiated cancer treatments.
