Eiger Announces Peginterferon Lambda - Lonafarnib Combination End of Treatment Results from Phase 2 LIFT HDV Study in Late Breaker Session at The Digital International Liver Congress™ 2020
PALO ALTO, Calif., Aug. 31, 2020 /PRNewswire/ -- Eiger BioPharmaceuticals, Inc (Nasdaq:EIGR), focused on the development and commercialization of targeted, first-in-class therapies for serious rare and ultra-rare diseases, today announced results from a late-breaker poster presentation at The Digital International Liver Congress™ 2020 of end of treatment results of the Phase 2 LIFT Lambda – Lonafarnib combination study in patients infected with hepatitis delta virus (HDV). The LIFT (Lambda InterFeron combo-Therapy) study is being conducted within the National Institutes of Health (NIH) at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Lambda is a first-in-class type III interferon in clinical development for HDV, the most severe form of human viral hepatitis.
"We have previously presented promising results from multiple studies at NIDDK that Lonafarnib reduces HDV RNA viral load in patients infected with HDV," said Christopher Koh, MD, Principal Investigator at the NIDDK. "Lambda and Lonafarnib combination Week 24 end of treatment results from the ongoing LIFT study represent a potential foundational combination treatment for HDV. We will present Week 48 end of follow-up results from the LIFT study in the future."
LIFT is a Phase 2a 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. Primary efficacy endpoint is > 2 log decline in HDV RNA at end of treatment. 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).
At Week 24 end of treatment, 25 of 26 patients (96%) achieved the Primary Endpoint of > 2 log decline in HDV RNA, 58% of patients were either Below Limit of Quantitation or Undetectable, and median HDV RNA decline was 3.2 log IU/mL (CI: 2.50-3.93, p<0.0001). Combination therapy with Lambda and Lonafarnib in chronic HDV patients appears to be well tolerated for up to 6 months in most patients. LIFT end of treatment results support continued exploration of this therapeutic combination in HDV.
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 Peginterferon Lambda (Lambda)
Eiger licensed worldwide rights to Lambda from Bristol-Myers Squibb. Eiger is developing Lambda as a monotherapy and in combination with Lonafarnib boosted with ritonavir. Lambda is an investigational agent and not yet approved for any indication. Eiger has received Orphan Designation by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA), and Fast Track and Breakthrough Therapy Designation by FDA for Lambda in HDV.
Lonafarnib has been dosed in over 120 HDV-infected patients across international academic centers and is in Phase 3 with a single, international, pivotal trial (D-LIVR Study). Lonafarnib has been granted Orphan Drug designation by the U.S. FDA and European Medicines Agency (EMA), Fast Track and Breakthrough Therapy Designation by the U.S. FDA and PRIME designation by the EMA. 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 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 lonafarnib for the treatment of Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) and Progeroid Laminopathies. FDA PDUFA date is November 20, 2020.
