Eiger BioPharmaceuticals Announces Abstracts and Presentations of Lonafarnib Data in Hepatitis Delta at the European Association for the Study of the Liver (EASL) Meeting
LOWR HDV – 2 is a dose finding study to identify optimal combination regimens of lonafarnib (LNF) and ritonavir (RTV) ± PEG-IFN-α, with efficacy and tolerability for longer term dosing to enable HDV RNA clearance. In this study, approximately 40 HDV infected patients have been enrolled to date into 9 groups of different doses of LNF in combination with RTV for dosing durations of 12 or 24 weeks. LNF doses range from 150 mg qd to 25 mg bid. Quantitative serum HDV RNA viral loads, biochemical parameters, and lonafarnib drug levels were measured. As of

About Sarasar® (lonafarnib)
Lonafarnib is a well-characterized, late-stage, orally active inhibitor of farnesyl transferase, an enzyme involved in modification of proteins through a process called prenylation. HDV uses this host cell process inside liver cells to complete a key step in its life cycle. Lonafarnib inhibits the prenylation step of HDV replication inside liver cells and blocks the virus life cycle at the stage of assembly. Since prenylation is carried out by a host enzyme, this compound may present a higher barrier to development of viral resistance mutations to therapy. Lonafarnib has been dosed in over 100 HDV-infected patients across international academic centers and is in Phase 2 development for HDV. Lonafarnib has been granted Orphan Drug Designation by the
About Hepatitis Delta Virus (HDV)
Hepatitis Delta (or Hepatitis D) is caused by infection with HDV and is considered to be one of the most severe forms of viral hepatitis in humans. Hepatitis D occurs only as a co-infection in individuals harboring Hepatitis B Virus (HBV). Hepatitis D leads to more severe liver disease than HBV alone and is associated with accelerated liver fibrosis, liver cancer, and liver failure. Hepatitis D is a disease with a significant impact on global health, which may affect up to approximately 15-20 million people worldwide. The prevalence of HDV varies among different parts of the world. Globally, HDV infection is reported to be present in approximately 4.3% to 5.7% of chronic Hepatitis B carriers. The prevalence of HDV in patients infected with chronic HBV is even higher in certain regions, including certain parts of
