"We are very pleased to conduct our first study with lonafarnib combined with ritonavir in HDV infected patients," said Heiner Wedemeyer, MD, Research Group Leader in the Department of Gastroenterology, Hepatology and Endocrinology at Hannover Medical School. "Many drugs are dose escalated or titrated to allow patients to acclimate to therapy and optimize treatment. The LOWR HDV - 4 protocol design enables us to investigate the efficacy and tolerability of lonafarnib in combination with ritonavir in HDV infected patients with an option to dose escalate or titrate at pre-specified times during the 24 week dosing period."
"Hepatitis delta causes the most aggressive form of human viral hepatitis, with fast progression to cirrhosis and other life-threatening complications, and is a major health burden all over the world," said Eduardo Martins, MD, DPhil, Senior Vice President of Liver and Infectious Diseases Drug Development at Eiger BioPharmaceuticals. "LOWR HDV – 4 is designed to help elucidate the antiviral potential of lonafarnib in combination with ritonavir in a longer duration study with the optionality of dose escalation, and we eagerly await results."
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 60 HDV-infected patients across international academic centers and is in Phase 2 development for HDV. Lonafarnib has been granted Orphan Drug Designation by the US FDA and European Medicines Agency (EMA), and Fast Track Designation by US FDA. Lonafarnib is not approved for any indication, and is licensed from Merck Sharp & Dohme Corp. (known as MSD outside of the United States and Canada).
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 5-6% 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 Mongolia, China, Russia, Central Asia, Pakistan, Turkey, Africa, and South America, with an HDV prevalence as high as 60% being reported in HBV-infected patients in Mongolia and Pakistan.
