Other Events.

On March 23, 2020, Eiger BioPharmaceuticals, Inc. (the “Company”) announced that it has completed submission to the U.S. Food and Drug Administration (the “FDA”) of a New Drug Application (an “NDA”) for lonafarnib for the treatment of Progeria and Progeroid Laminopathies. The FDA previously granted Breakthrough Therapy Designation and Rare Pediatric Disease Designation to lonafarnib, which enables eligibility for Priority Review, if relevant criteria are met. The Company expects to hear from the FDA regarding submission acceptance and Priority Review within 60 days of submission of the NDA.

Lonafarnib, an oral farnesyltransferase inhibitor, has demonstrated extended survival in children and young adults with Progeria, an ultra-rare and fatal disease that causes premature aging in children. Without treatment, children with Progeria die of heart disease at an average age of 14.5 years.
