Mirum Pharmaceuticals, Inc.
A pharmaceutical company focused on rare diseases, it markets three FDA-approved medicines: Livmarli for the severe itching of certain inherited liver conditions, Ctexli for cerebrotendinous xanthomatosis, and Cholbam for bile acid disorders. It was founded in 2018 by a team that revived its lead drug after pharmaceutical giant Shire set it aside, and its name comes from Latin, meaning "wonder" or "marvel."

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: +6.55M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
