Eiger Announces Results of Investigator Sponsored Study in Outpatients with Mild and Uncomplicated COVID-19
The primary endpoint was duration of viral shedding, determined by time to first of two consecutive negative tests for SARS-CoV-2 by qRT-PCR. The secondary endpoint was reducing duration of symptoms and hospitalization in patients with mild COVID-19. A total of 120 patients were randomized 1:1 to a single subcutaneous dose of Lambda or normal saline placebo. Patients were followed for 28 days.
No difference was demonstrated in duration of SARS-CoV-2 viral shedding and time to symptom resolution when compared with placebo. Median time to cessation of viral shedding in both groups was 7 days. Lambda was well-tolerated with few adverse events, which included elevated transaminases which self-resolved.
The study was co-led by
"We now know that untreated patients with mild COVID-19 clear virus quickly. Published reports have demonstrated evidence of a therapeutic benefit of interferons in hospitalized patients with more advanced COVID-19 disease," said
"Lambda is in late stage development for the treatment of Hepatitis Delta Virus (HDV), the most severe form of human viral hepatitis, and HDV is our lead clinical program," 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.
This study is one of six international, investigator sponsored studies evaluating Lambda in COVID-19. Other sites include patients with more advanced COVID-19 at

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.
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 ready to enter 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
