About Peginterferon Lambda (Lambda)
Lambda is a well-characterized, first in class, type III interferon (IFN) that stimulates immune responses that are critical for the development of host protection during viral infections.  Lambda targets type III IFN receptors which are distinct from the type I IFN receptors targeted by IFN alfa.  Lambda type III receptors are highly expressed on hepatocytes with limited expression on hematopoietic and central nervous system cells, which may reduce off-target effects and improve tolerability of Lambda. 

Lambda is Phase 3 ready in development as a treatment for HDV.  Eiger has received Orphan Designation by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA), and Fast Track and Breakthrough Designation by FDA for Lambda in HDV.  Lambda is not yet approved for any indication.  Eiger licensed worldwide rights to Lambda from Bristol-Myers Squibb

About Lonafarnib
Lonafarnib is a well-characterized, late-stage, oral inhibitor of farnesyl transferase, an enzyme involved in modification of proteins through a process called prenylation, a vital process in the life cycle of HDV.  Blocking prenylation of the large delta hepatitis antigen (LDHAg) reduces HDV replication. 

Lonafarnib has been dosed in over 150 HDV-infected patients across international academic centers and is in Phase 3 global, pivotal trial (D-LIVR Study).  Lonafarnib has been granted Orphan Drug designation by the U.S. FDA and European Medicines Agency (EMA), Fast Track and Breakthrough designation by U.S. FDA and PRIME designation by the EMA.  Lonafarnib is not approved for any indication.  Eiger licensed worldwide rights to Lonafarnib from Merck Sharp & Dohme Corp. (known as MSD outside of the United States and Canada).

About Eiger
Eiger is a late-stage biopharmaceutical company focused on the development and commercialization of first-in-class, well-characterized drugs for serious rare and ultra-rare diseases for patients with high unmet medical needs. 

Eiger's lead clinical programs target Hepatitis Delta Virus (HDV) infection, the most serious form of human viral hepatitis.  Eiger is developing two complementary treatments for HDV.  Lonafarnib is a first-in-class, oral prenylation inhibitor in a global Phase 3 trial.  Peginterferon lambda is a first-in-class, well-tolerated type III interferon entering Phase 3.

Eiger has filed an NDA and MAA for lonafarnib for the treatment of Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) and Progeroid Laminopathies.  FDA PDUFA date is November 20, 2020
