Eiger BioPharmaceuticals, Inc. was a commercial-stage biopharmaceutical company focused on developing and commercializing targeted therapies for rare and ultra-rare diseases. Its portfolio included Zokinvy®, the first and only approved treatment for Hutchinson-Gilford Progeria Syndrome (Progeria) and progeroid laminopathies, and Ravicti®, approved for treating urea cycle disorders. In April 2024, Eiger BioPharmaceuticals and its direct U.S. subsidiaries filed for voluntary protection under Chapter 11 of the U.S. Bankruptcy Code to facilitate an asset sale. The company subsequently sold Zokinvy® and Ravicti® to Sentynl Therapeutics, Inc. Eiger is currently winding down its remaining operations.
Previously served as the central hub for corporate operations, strategic planning, R&D oversight, and administrative functions. Post-Chapter 11, its function is minimal, related to administering the bankruptcy process with a skeleton staff.
The former headquarters was situated in Silicon Valley, a key biotech hub. Specific architectural details of the leased office space are not widely publicized.
Prior to restructuring, Eiger likely fostered a mission-driven culture focused on rare diseases. Currently, the work environment is centered on managing the Chapter 11 process and wind-down activities, involving a very small team of remaining employees and restructuring professionals.
Historically, the Palo Alto location was significant for its proximity to innovation, talent, and capital within the biotech industry. Its current physical significance is greatly diminished due to the company's operational wind-down.
Historically, Eiger BioPharmaceuticals' global presence was characterized by its international clinical trials for rare disease therapies and the global commercialization of Zokinvy®. Following the Chapter 11 filing and the sale of its key commercial assets, its global operational activities have been significantly curtailed as the company proceeds with its wind-down plan.
