A Two-Drug Combo Cleared Hepatitis D Virus in 46% of Patients After Treatment Ended

Scientists tested whether combining two drugs—bulevirtide and peginterferon alfa-2a—works better than either drug alone for chronic hepatitis D. Nearly half of patients who got the high-dose combination had no detectable virus six months after finishing treatment, compared to just 12% on bulevirtide alone.

What the trial was testing

The MYR 204 enrolled 175 patients with liver disease. The study was sponsored by Gilead Sciences and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

It was mid-stage testing (phase 2/3). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.

What the results showed

46% of patients on the combination had no detectable hepatitis D virus six months after treatment ended.

These findings — that had no detectable virus six months after stopping treatment — were published in the The New England journal of medicine and represent the headline result of the study.

Researchers tracked outcomes across 175 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with liver disease, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

This was a mid-stage study testing different combinations. Bulevirtide is FDA-approved for hepatitis D, but the combination approach tested here is not yet standard care. If you have hepatitis D, talk to your doctor about approved bulevirtide treatment and whether peginterferon might be an option for you.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
