Eiger Initiates Rolling Submission of New Drug Application (NDA) with FDA for Lonafarnib for Treatment of Progeria and Progeroid Laminopathies
Lonafarnib has been granted Orphan Drug Designation for Progeria and Progeroid Laminopathies by the FDA and EMA and Breakthrough Therapy Designation and Rare Pediatric Disease Designation by the FDA. The FDA agreed that the Lonafarnib submission could be a rolling NDA, allowing completed portions of an NDA to be submitted and reviewed by the FDA on an ongoing basis. Eiger plans to complete the NDA rolling submission in first quarter of 2020.
"Our discussions with
Progeria, also known as Hutchinson‐Gilford Progeria Syndrome (HGPS), is a rare and fatal genetic condition of accelerated aging in children. Progeria is caused by a point mutation in the LMNA gene, which encodes the lamin A protein, yielding the farnesylated aberrant protein, progerin. Lamin A protein is part of the structural scaffolding that holds the nucleus together. Children with Progeria die of the same heart disease that affects millions of normally aging adults (arteriosclerosis), but at an average age of 14.5 years. Disease manifestations include severe failure to thrive, scleroderma‐like skin, global lipodystrophy, alopecia, joint contractures, skeletal dysplasia, global accelerated atherosclerosis with cardiovascular decline, and debilitating strokes. It is estimated that 400 children worldwide have Progeria.
About Progeroid Laminopathies
Progeroid Laminopathies are genetic conditions of accelerated aging caused by a constellation of mutations in the lamin A and/or Zmpste24 genes yielding farnesylated proteins that are distinct from progerin. While non‐progerin producing, these genetic mutations result in disease manifestations with phenotypes that have overlap with, but are distinct from, Progeria. Collectively, worldwide prevalence of Progeroid Laminopathies is likely greater than Progeria.
Lonafarnib is a well‐characterized, late‐stage, orally active inhibitor of farnesyltransferase, an enzyme involved in modification of proteins through a process called prenylation. Progerin is a farnesylated aberrant protein that researchers believe cannot be cleaved, resulting in tight association with the nuclear envelope, which leads to changes in nuclear envelope morphology and subsequent cellular damage.
Lonafarnib blocks the farnesylation of progerin and has been dosed in over 80 children with Progeria at

Eiger is a late stage biopharmaceutical company focused on the development and commercialization of a pipeline of first-in-class, well-characterized drugs for serious rare and ultra-rare diseases for patients with high unmet medical needs and for which no approved therapies exist.
The company's lead program is in Phase 3, developing lonafarnib, a first-in-class prenylation inhibitor for the treatment of Hepatitis Delta Virus (HDV) infection. The company is rapidly advancing peginterferon lambda, a first-in-class interferon, toward registration for the treatment of HDV. Eiger has initiated a rolling NDA submission for lonafarnib to treat Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) and Progeroid Laminopathies with plans to complete NDA submission followed by an MAA submission in the first quarter of 2020.
