Clinical Trials

Clinical trials are research studies that test new potential treatments for a disease. Talk to your doctor about possible clinical trials that could be helpful to you.

Glossary: HBV = Hepatitis B, CHB = Chronic hepatitis B, HDV = Hepatitis D, CHD = Chronic hepatitis D, ALT = Alanine aminotransferase, AST = Aspartate aminotransferase, EOT = End of Treatment, NTCP = Sodium/taurocholate cotransporting polypeptide, LNF-containing regimens = Lonafarnib-containing regimens


Phase 3 Study of the Efficacy and Safety of Lonafarnib / Ritonavir With and Without Pegylated Interferon-Alfa-2a (D-LIVR) - U.S. and International

Two LNF-containing regimens will be evaluated in the D-LIVR Phase 3 study: (1) LNF/RTV/PEG IFN-alfa-2a and (2) LNF/RTV. Each of these arms will have efficacy endpoints that measure clinical benefit with regard to viral suppression and ALT normalization. For each LNF-containing regimen, a composite endpoint of EOT (48 weeks) virologic response and ALT normalization will be used. Virologic response will be defined as a 2 log10 IU/mL reduction from baseline. Contact: John Ferraro 650-272-6138 or DLIVR@eigerbio.com and refer to identifier NCT03719313.

Phase 2 Study of Ezetimibe for Patients With Chronic Hepatitis D – Pakistan

Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry that include two hydrophobes and one hydrogen bond acceptor. Therapy with ezetimibe may lead to decline in HDV levels. The aim of the study is to evaluate the utility of ezetimibe in patients with CHD.
