Mirum’s liver infection drug lowers virus levels in late-stage study
The drug was well tolerated, and 56% of patients on the lower dose and 45% on the higher dose improved at 24 weeks, Mirum said.
On Monday, Mirum Pharmaceuticals announced its experimental drug Brelovitug met the primary goal of a late-stage study, successfully reducing hepatitis D virus levels in patients.
Brelovitug targets chronic hepatitis delta, a liver infection affecting about 230,000 people in the US and Europe who are already infected with hepatitis B, a condition causing severe symptoms and potential liver damage.
At 24 weeks, 56% of patients given 300 milligrams of Brelovitug and 45% given 900 milligrams showed reduced virus levels and normal liver enzyme levels, compared with 0% in the delayed-treatment group.
RBC Capital Markets analyst Lisa Walter said Brelovitug has "a better benefit/risk profile," positioning it as best-in-class versus Gilead's Hepcludex, while Mirum reported the treatment was well tolerated across all dose groups.
Mirum expects Brelovitug to generate peak sales of at least $1 billion and plans to submit a marketing application to the FDA in the first half of 2027 following full study results presentation.
