What Mirum Pharmaceuticals, Inc. reported on August 5, 2026

The quarter ending June 30, 2026, against the same quarter a year earlier.

These are single quarters, not a trailing year — the figures elsewhere on this site cover twelve months and will be much larger. A seasonal business swings a long way between the two: ServiceNow earns $2.0B of free cash flow in its December quarter and $0.5B in its June one.

Compared against the same quarter a year earlier, not against an analyst forecast. A “beat” or “miss” needs a consensus estimate, which is licensed data we do not carry — and getting it wrong is worse than leaving it out.

What management said

“Mirum delivered another strong quarter, with continued commercial momentum supporting an increase to our full-year net product sales guidance and launch readiness for the upcoming potential approval of zilurgisertib,”

What Mirum Pharmaceuticals, Inc. does

Volixibat is an investigational oral, minimally absorbed agent designed to selectively inhibit the ileal bile acid transporter (IBAT). Volixibat may offer a novel approach in the treatment of adult cholestatic diseases by blocking the recycling of bile acids, through inhibition of IBAT, thereby reducing bile acids systemically and in the liver. Volixibat is currently being evaluated in Phase 2b studies for primary sclerosing cholangitis (PSC) (VISTAS study) and primary biliary cholangitis (PBC) (VANTAGE study). In 2026, Mirum shared that the Phase 2b VISTAS study of volixibat in PSC met its primary endpoint, with statistically significant and clinically meaningful reductions in pruritus observed in patients treated with volixibat. Volixibat’s safety profile in the study was generally consistent with the known effects of IBAT inhibition. Volixibat has been granted FDA Breakthrough Therapy designation for the treatment of cholestatic pruritus due to PSC. In 2024, Mirum announced positive interim results from the Phase 2b VANTAGE study of volixibat in PBC. No new safety signals were observed in the study. Volixibat has been granted FDA Breakthrough Therapy designation for the treatment of cholestatic pruritus due to PBC.
