Eiger BioPharmaceuticals Announces First Patient Enrolled in LIMT-2: A Phase 3 Study of Peginterferon Lambda in Patients with Chronic Hepatitis Delta Virus (HDV) Infection
Eiger BioPharmaceuticals (Nasdaq:EIGR) has announced the enrollment of the first patient in its Phase 3 LIMT-2 study, examining Peginterferon Lambda for treating chronic Hepatitis Delta Virus (HDV). The study aims to enroll 150 patients across 50 sites in 13 countries, comparing a treatment group to a no-treatment group followed by treatment. The primary goal is to assess the Durable Virologic Response (DVR) at 24 weeks post-treatment. Eiger is pursuing regulatory approval, with Peginterferon Lambda already receiving Orphan Designation and Fast Track status from the FDA.

PALO ALTO, Calif., Dec. 21, 2021 /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 rare diseases, today announced that the first patient has been enrolled in LIMT-2, a Phase 3 study of 48-week treatment with Peginterferon Lambda in patients with chronic hepatitis delta virus (HDV) infection. LIMT-2 will include 50 sites across 13 countries and a target enrollment of 150 patients.
"LIMT-2 is a single pivotal study to support approval of Peginterferon Lambda for the treatment of HDV," said David Cory, President and CEO of Eiger. "We believe that a well tolerated interferon will be preferred by physicians and HDV patients, leading to better compliance and improved outcomes. We now have two promising investigational treatments in Phase 3 for HDV, Lonafarnib and Peginterferon Lambda, which we expect will become foundational therapies to treat and cure HDV."
"There are now multiple late-stage, promising investigational treatments in development for HDV, each with a different mechanism of action and formulation for different routes of administration," said Pietro Lampertico, MD, PhD, LIMT-2 Principal Investigator, Professor of Gastroenterology, Director of the Gastroenterology and Hepatology Division, and Head of the "A. M. e A. Migliavacca" Center for Liver Disease at the Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico, University of Milan, Italy. "It's an exciting time for both patients and physicians as we look toward the potential of multiple approved treatment options for the greater than 12 million HDV patients around the globe suffering from this severe disease."
About Phase 3 LIMT-2 Study
LIMT-2 is a randomized, open-label, parallel-arm study that will randomize patients with chronic HDV infection to one of two treatment groups, applying a 2:1 allocation ratio: Peginterferon Lambda 180 mcg QW for 48 weeks with 24 weeks follow-up (Arm 1, n=100), or no treatment for 12 weeks followed by Peginterferon Lambda treatment for 48 weeks with 24 weeks of follow-up (Arm 2, n=50). All patients will receive tenofovir or entecavir throughout the study duration.
The primary analysis will compare the proportion of patients with a Durable Virologic Response (DVR), defined as HDV RNA below the limit of quantitation (BLQ) at 24-weeks post-treatment in the Peginterferon Lambda treatment group (Arm 1) to the proportion of patients with HDV RNA BLQ after 12 weeks of no treatment in the comparator group (Arm 2). This post-treatment DVR endpoint is most meaningful for both regulatory agencies and physicians as it demonstrates durability of response to treatment and potential for an HDV cure. Approximately 150 patients will be enrolled in 13 countries across 50 investigator sites.
About Peginterferon Lambda
Peginterferon 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. Peginterferon Lambda targets type III IFN receptors which are distinct from the type I IFN receptors targeted by IFN alfa, resulting in activation of the same Jak-STAT signal transduction cascade. Lambda type III receptors are highly expressed on hepatocytes with limited expression on hematopoietic and central nervous system cells, which may reduce off-target effects and improve tolerability of Peginterferon Lambda.
In Phase 2, Peginterferon Lambda was dosed once weekly in HDV infected patients for 48 weeks with 24-week follow-up.
Eiger licensed worldwide rights to Peginterferon Lambda from Bristol-Myers Squibb. Eiger is developing Peginterferon 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 Peginterferon Lambda in HDV.
About Hepatitis Delta Virus (HDV)
HDV is the most severe form of human viral hepatitis. HDV occurs only as a co-infection in individuals infected with hepatitis B virus (HBV). HDV leads to more severe liver disease than HBV alone and is associated with accelerated liver fibrosis, liver cancer, and liver failure. It is estimated that
HDV is a disease with a significant impact on global health, which may affect greater than 12 million people worldwide. Globally, HDV infection is reported to be present in approximately
