Eiger BioPharmaceuticals Announces Outlook and Planned 2022 Catalysts and Milestones

PALO ALTO, Calif., Jan. 6, 2022 /PRNewswire/ -- Eiger BioPharmaceuticals, Inc. (NASDAQ:EIGR), a commercial-stage biopharmaceutical company focused on the development of innovative therapies to treat and cure Hepatitis Delta Virus (HDV) and other serious diseases, today provided the company's outlook across multiple pipeline programs and operations, including planned 2022 catalysts and milestones.

"This is a pivotal year for Eiger as we plan for topline data from the landmark D-LIVR study by year end.  D-LIVR is the largest trial conducted in HDV and if positive will support regulatory filings for Lonafarnib-based regimens," said David Cory, President and CEO of Eiger.  "HDV is a large unmet medical need with over 12 million people suffering from this devastating disease around the globe.  Our second registration enabling clinical trial in HDV, LIMT-2, a Phase 3 study of Peginterferon Lambda, is now enrolling and dosing.  Lonafarnib and Peginterferon Lambda are well positioned to become foundational therapies to treat and cure HDV."
