Eiger Announces Positive Peginterferon Lambda - Lonafarnib Combination End of Study Results from Phase 2 LIFT HDV Study in Late-Breaker Session at The Liver Meeting Digital Experience™ 2020
PALO ALTO, Calif., Nov. 17, 2020 /PRNewswire/ -- Eiger BioPharmaceuticals, Inc. (Nasdaq:EIGR), focused on the development and commercialization of first-in-class therapies for serious rare and ultra-rare diseases, today announced a late-breaker oral presentation of Phase 2 LIFT (Lambda InterFeron combo-Therapy) results at The Liver Meeting Digital Experience™ 2020. Week 48 (24 weeks post-treatment) end of study results were presented. Peginterferon lambda (Lambda) is a first-in-class type III interferon in development for hepatitis delta virus (HDV) infection, the most severe form of human viral hepatitis.
The LIFT study was conducted within the National Institutes of Health (NIH) at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and was led by Christopher Koh, MD, Principal Investigator at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
LIFT is a Phase 2, open-label study of 26 adult patients with chronic HDV treated with Lambda 180 mcg once weekly in combination with Lonafarnib 50 mg boosted with ritonavir 100 mg twice daily for 24 weeks followed by 24 weeks of post-treatment follow-up. Primary efficacy endpoint was > 2 log decline in HDV RNA at Week 24 (end of treatment). Secondary endpoints included histology (> 2 point improvement in histological activity index or HAI) at Week 48 (end of follow-up). Liver biopsies were obtained in all 26 patients at baseline (pretreatment) and in 20 patients at Week 48 (24 weeks post-treatment, end of study). Median baseline evaluations included: ALT (64 IU/mL), AST (47 IU/mL), Ishak Fibrosis (3), modified HAI inflammation (9), HBV DNA (< 20 IU/mL) and log HDV RNA (4.74 IU/mL).
Twenty-two of 26 patients completed 24 weeks of treatment. At Week 24 (end of treatment), by per-protocol analysis, 17 of 22 patients (77%) achieved the primary endpoint of > 2 log decline in HDV RNA, 11 of 22 patients (50%) were either HDV RNA below limit of quantitation (BLOQ) or HDV RNA undetectable, and median HDV RNA decline was 3.2 log IU/mL (CI: 2.50-3.93, p<0.0001). At Week 48 (24 weeks post-treatment), 5 of 22 patients (23%) maintained HDV RNA BLOQ or were HDV RNA undetectable, 11 of 20 patients (55%) demonstrated improvement in Histology Activity Index (HAI), and 6 of 20 patients (30%) achieved the secondary endpoint of > 2 point improvement in HAI.
Adverse events were mostly mild to moderate and included GI-related side effects, weight loss, hyperbilirubinemia, and anemia. Per-protocol dose reductions occurred in 3 patients and discontinued in 4 patients, and were mostly due to known side effects related to peginterferon lambda.

About LIFT Study
About Hepatitis Delta Virus (HDV)
Hepatitis delta is a disease with a significant impact on global health, which may affect up to 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.
Eiger's lead clinical programs target Hepatitis Delta Virus (HDV) infection, the most serious form of human viral hepatitis. Eiger is developing two complementary treatments for HDV. Lonafarnib is a first-in-class, oral prenylation inhibitor in a global Phase 3 trial. Peginterferon lambda is a first-in-class, well-tolerated type III interferon entering Phase 3.
Eiger has filed an NDA and MAA for the treatment of Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) and Progeroid Laminopathies. FDA PDUFA date is November 20, 2020.
