Eiger BioPharmaceuticals Announces First COVID-19 Patients Dosed with Peginterferon Lambda
Approximately 120 patients will be randomized 1:1 to a single subcutaneous dose of Lambda or normal saline placebo to evaluate the efficacy of Lambda in reducing the duration of viral shedding of SARS-CoV-2 virus and in reducing duration of symptoms and hospitalization in patients with mild COVID-19. Patients will be followed for 28 days.
Lambda interferon plays a key role in the targeted innate immune response against viral pathogens that infect the respiratory tract. Upon infection of airway epithelial cells, type III IFNs, like lambda interferon, are produced first and act as the initial line of defense to limit virus spread at the epithelial barrier without triggering inflammation. The study will investigate the hypothesis that Lambda may be most effective in patients who have confirmed infection with mild symptoms in order to reduce duration and severity of COVID-19.
"SARS-CoV-2 induces very weak expression of interferons in infected cells," said
About Peginterferon Lambda (Lambda)
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. Lambda targets type III IFN receptors which are distinct from the type I IFN receptors targeted by IFN alfa. Binding leads to activation of JAK-STAT signaling pathway and upregulation of numerous IFN-stimulated genes (ISGs). IFN lambda receptors are largely restricted to cells and tissues of epithelial origin, including respiratory epithelial cells.
IFN lambdas are critical for maintaining a balanced antiviral response in the respiratory tract. They are induced at lower viral burden before type I IFNs to limit the initial infection by inducing viral resistance to cells and helping them deal with the virus load. IFN lambda lacks the strong pro-inflammatory effects of type I IFNs and are tissue-protective and anti-inflammatory. Administration of IFN lambda has been shown to suppress viral replication while stopping the 'cytokine storm' from developing.

Eiger is a late-stage biopharmaceutical company focused on the development and commercialization of first-in-class, well-characterized drugs for serious rare and ultra-rare diseases for patients with high unmet medical needs, for which no approved therapies exist.
Eiger has completed an NDA and MAA submission for lonafarnib for the treatment of Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) and Progeroid Laminopathies. Eiger has also established a global Managed Access Program, expected to span greater than 40 countries, to ensure all children and young adults with Progeria and Progeroid Laminopathies have access to treatment.
The company's lead program is in Phase 3, developing lonafarnib, a first-in-class oral prenylation inhibitor for the treatment of Hepatitis Delta Virus (HDV) infection. The company is also advancing peginterferon lambda, a first-in-class interferon, toward registration for the treatment of HDV.
