EASL Congress 2026:
EIT Pharma presented new analysis from the lonafarnib development program at EASL Congress 2026. The D-LIVR study is the largest clinical trial ever conducted in chronic hepatitis D, enrolling more than 400 subjects across 21 countries. Lonafarnib is currently the only late-stage investigational therapy for CHD with an oral route of administration.

Presentations included:

Oral Presentation: Lonafarnib/ritonavir and peg-interferon alfa drive histological improvement and inflammation resolution in chronic hepatitis D: results of the multicenter phase 3 D-LIVR study; presented by Dr. Saeed Hamid, “Viral Hepatitis B/D – New Therapies” session, May 29.
Poster Presentation: Lonafarnib/ritonavir with or without peginterferon achieves rapid, durable responses in chronic hepatitis D: extended analyses from the phase 3 D-LIVR trial; “Viral Hepatitis B and D: New therapies, unapproved therapies or strategies” session, May 27.

“People living with chronic hepatitis D face a serious and progressive liver disease with limited treatment options,” said Dr. Kawas in the press announcement for the presentations. “These new analyses from D-LIVR deepen our understanding of lonafarnib-based regimens for CHD treatment. At EIT Pharma, our focus is advancing therapies where the unmet need is high, the science is rigorous, and the potential patient impact is meaningful.”

EIT Pharma Progress

Just over a year after restarting the lonafarnib program, EIT Pharma has defined a potential regulatory path forward, including engagement with the U.S. Food and Drug Administration, re-analysis of D-LIVR study data, and preparation for commercialization. Lonafarnib for CHD has previously received FDA Breakthrough Therapy designation, Fast Track designation, and Orphan Drug designation. EIT Pharma expects to provide additional data from the D-LIVR program to the medical community over the coming months.

“The renewed momentum behind lonafarnib is truly exciting,” said Jeffrey Glenn, M.D., Ph.D., professor of medicine, gastroenterology and hepatology, at Stanford University, scientific cofounder and advisor to EIT Pharma. “As the only oral option in late-stage development for chronic hepatitis D, this program represents a critical opportunity for patients with significant unmet medical needs. I’m excited to work with the experienced team at EIT to advance this potential breakthrough therapy …”

About Lonafarnib
Lonafarnib is an oral farnesyltransferase inhibitor. In chronic hepatitis D, it is thought to exert antiviral activity by inhibiting the prenylation-dependent assembly process required for the formation of new HDV virions. As the only late-stage investigational therapy for CHD with an oral route of administration, lonafarnib is being developed as a potentially accessible option for patients living with this chronic and serious liver disease. Lonafarnib is not FDA approved for the treatment of chronic hepatitis D.
