Eiger BioPharmaceuticals Announces Results from Multiple Presentations at the European Association for the Study of the Liver (EASL) International Liver Congress™ 2022

PALO ALTO, Calif., June 27, 2022 /PRNewswire/ -- Eiger BioPharmaceuticals, Inc. (Nasdaq: EIGR), a commercial-stage biopharmaceutical company focused on the development of innovative therapies to treat and cure hepatitis delta virus (HDV) and other serious diseases, today announced data presented at the European Association for the Study of the Liver (EASL) International Liver Congress™ 2022 that took place June 22-26 in London, United Kingdom.

"We are pleased that EASL recognized our HDV platform with multiple presentations this year highlighting both the lonafarnib and peginterferon lambda programs," said David Cory, President and CEO, Eiger. "Our Phase 3 D-LIVR study will produce the single largest cohort of patient data from a well-controlled global study of HDV. We look forward to continued collaboration with investigators and key opinion leaders to mine this deep data set, providing additional insights, with a goal of improving outcomes for the global HDV patient population. In parallel, we are preparing for topline results from the landmark D-LIVR study by end of year."

Abstract #3442: Clinical Features Predictive of Cirrhosis in a Large Cohort of Patients with Chronic Hepatitis Delta Infection - Insights from the D-LIVR Trial; Etzion, O., Asselah, T., Lampertico, P. et al. 
Conclusions:  In the on-going Phase 3 D-LIVR study, the largest cohort to date of patients with chronic HDV, alarmingly high rates of cirrhosis were seen among patients with compensated liver disease at a relatively young mean age. Over 40% of cirrhotic patients were ≤ 45 years old. A high index of suspicion for cirrhosis should be maintained in this population, especially in older patients and in those showing subtle changes in markers of synthetic liver function and portal hypertension.

Abstract #2072: Mathematical Modeling of HDV RNA Kinetics Suggests High Peginterferon Lambda Efficacies in Blocking Viral Production and Infection: Insights from the LIMT-1 Study; Cardozo-Ojeda, E.F., Etzion, O. et al. 
Conclusions:  Previously reported end of study data of Phase 2 LIMT-1 trial of peginterferon lambda (Lambda) monotherapy showed that Lambda therapy had better antiviral activity and tolerability compared to historical data for peginterferon alfa and identified four main HDV RNA kinetic patterns under Lambda therapy. This study provides, for the first time, a dynamic description of HDV response under Lambda monotherapy. Lambda blocks viral production with high efficacy. HDV kinetics depend on Lambda efficacy, the baseline fraction of noninfected hepatocytes and their proliferation rates.

Abstract #1904: Lonafarnib Combination with Peginterferon Lambda Diminished Triphasic HDV Kinetic Pattern Seen Under Lambda Monotherapy: the LIFT-1 HDV Study; Duehren, S., Dahari, H., Heller, T. et al. 
Conclusions:  End of study data of Phase 2 LIFT-1 study of peginterferon lambda combined with lonafarnib was previously reported (AASLD 2020). The goal of the current study was to characterize HDV RNA, HBV DNA, HBsAg and ALT kinetics during and after combination therapy. Combination therapy was associated with better treatment success (≥ 2 log decline HDV RNA) compared to Lambda monotherapy. No null responders with Lambda + Lonafarnib. Reduction of the triphasic kinetic pattern suggests that the addition of Lonafarnib may decrease production/release of HDV RNA. Kinetic patterns observed in Lambda + Lonafarnib and Lambda monotherapy are associated with treatment response.

Eiger is a commercial-stage biopharmaceutical company focused on the development of innovative therapies to treat and cure hepatitis delta virus (HDV) and other serious diseases. The Eiger HDV platform includes two first-in-class therapies in Phase 3 that target critical host processes involved in viral replication. Eiger is also developing peginterferon lambda as a therapeutic for COVID-19 and reported positive results from TOGETHER, a Phase 3 investigator-initiated study.

All five Eiger rare disease programs have been granted FDA Breakthrough Therapy designation: lonafarnib and peginterferon lambda for HDV, Zokinvy for progeria, and avexitide for both congenital hyperinsulinism and post-bariatric hypoglycemia.
