Jon Wolleben's questions to Mirum Pharmaceuticals Inc (MIRM) leadership • Q2 2025
Question
Jon Wolleben of Citizens JMP asked for evidence that pruritus in PSC is driven by excess bile acids and inquired about any sales inflection for the bile acid portfolio (CTX) since gaining the ability to promote it.
Answer
Chief Medical Officer Joanne Quan explained that while bile acids play a role, the core issue in PSC is cholestasis, and serum bile acid levels are likely less important than in other indications. COO & President Peter Radovich stated that for the bile acid portfolio, he expects a "gradual steady build" in sales rather than a sharp inflection due to laborious patient finding.
