We are a clinical-stage biopharmaceutical company developing treatments for rare, chronic, and serious infectious diseases with high unmet needs. Our initial product candidate is epetraborole, a once-daily oral treatment for patients with chronic non-tuberculous mycobacterial, or NTM, lung disease. Epetraborole has broad spectrum antimycobacterial activity through inhibition of an essential and universal step in bacterial protein synthesis. Its novel mechanism of action is enabled by boron chemistry, our core technology approach. We plan to conduct a Phase 2/3 pivotal clinical trial in treatment-refractory Mycobacterium avium complex, or MAC, lung disease, which is the most common type of NTM lung disease. Interim data from our completed Phase 1b dose-ranging study of epetraborole administered orally for 28 days in healthy volunteers in Australia and data from our two nonclinical chronic toxicology studies (six-month rats and nine-month non-human primates) have informed our selection of a 500 mg once-daily dose for our Phase 2/3 pivotal clinical trial in treatment-refractory MAC lung disease patients. We believe our Phase 2/3 pivotal clinical trial design, which is under review by the U.S. Food and Drug Administration, or FDA, has the potential to be sufficient for regulatory approval in the United States
