Eiger BioPharmaceuticals Announces Positive Phase 2 LIMT Study End of Treatment Data with Pegylated Interferon Lambda Monotherapy in Hepatitis Delta Virus (HDV) Infection
At Week 48, patients in the 180 μg Lambda treated group experienced a -2.4 log10 mean decline in HDV-RNA, with 6 of 10 (60%) experiencing ≥2 log10 decline, 4 of 10 (40%) patients were HDV-RNA negative at end of treatment. At Week 48, patients in the 120 μg Lambda treated group experienced a -1.5 log10 mean decline in HDV RNA, with 6 of 14 (42.9%) experiencing ≥2 log10 decline, 2 of 14 (14.3%) patients were HDV-RNA negative at end of treatment. The most common adverse events included mild to moderate flu-like symptoms and elevated transaminase levels.
"Lambda interferon demonstrated better tolerability in HDV-infected patients who were previously treated with Alfa interferon," said LIMT HDV Study Co-Lead Investigators,
"Lambda is the second proprietary product in the Eiger pipeline for development as a monotherapy or combination therapy in HDV," said
The company plans to share additional details from the Lambda LIMT study at the following AASLD 2018 events in

About Pegylated Interferon Lambda (Lambda)
Lambda is a well-characterized, late-stage, 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. These type III receptors are highly expressed on hepatocytes with limited expression on hematopoietic and central nervous system cells, which reduce off-target effects and improve tolerability of Lambda. Although Lambda does not use the IFN alfa receptor, signaling through either the IFN Lambda or IFN alfa receptor complexes results in the activation of the same Jak-STAT signal transduction cascade.

About LIMT (Lambda Monotherapy) Study
LIMT HDV is a 1:1 randomized, open-label study of Lambda 120 or 180 μg subcutaneous injections administered weekly for 48 weeks in 33 patients with chronic HDV. End of treatment will be followed by a treatment-free 24-week observation period. The primary objective of the Phase 2 study is to evaluate the safety, tolerability, and efficacy of treatment with two dose levels of Lambda monotherapy in patients with chronic HDV infection. All patients are administered an anti-hepatitis B virus nucleos(t)ide analog throughout the study. LIMT HDV is an international study with sites in
About LIFT (Lambda Combo Therapy) Study
LIFT (Lambda InterFeron combo-Therapy) is an open-label, Phase 2 study evaluating Lambda + LNF + RTV in approximately 26 HDV-infected patients. Patients will be dosed for 24 weeks + undergo follow up for 24 weeks. Primary endpoint will be ≥ 2 log decline in HDV RNA at end of treatment. Secondary endpoints will include histology (> 2 point improvement in histological activity index and no progression in fibrosis) at end of treatment. LIFT is being conducted within the
About Hepatitis Delta Virus (HDV)
Hepatitis Delta is caused by infection with HDV and is considered to be one of the most severe forms of viral hepatitis in humans. Hepatitis delta occurs only as a co-infection in individuals harboring Hepatitis B Virus (HBV). Hepatitis delta leads to more severe liver disease than HBV alone and is associated with accelerated liver fibrosis, liver cancer, and liver failure. Hepatitis delta 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
Eiger is a clinical-stage biopharmaceutical company focused on the accelerated development and commercialization of targeted therapies for rare and ultra-rare diseases. We innovate by developing well-characterized drugs acting on newly identified or novel targets in rare diseases. Our mission is to systematically reduce the time and cost of the drug development process to more rapidly deliver important medicines to patients. Lonafarnib is our lead compound advancing into Phase 3 with a single, pivotal trial to treat HDV to initiate by the end of the year. Lonafarnib is also advancing toward an NDA for the treatment of Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) in 2019.
