Profile
Builds its business around LINZESS, a prescription treatment for IBS-C and CIC, and a partner-led commercialization model. Develops apraglutide for adults with short bowel syndrome and intestinal failure.
Commercializes LINZESS, its in-house-discovered linaclotide product for adults with IBS-C and CIC. AbbVie leads commercialization in the United States, while AstraZeneca covers China and Astellas covers Japan.
Develops apraglutide, a long-acting synthetic GLP-2 analogue, for adults with short bowel syndrome and intestinal failure. Access to the program is limited to clinical trials as the STARS program continues.
Operates as a single human-therapeutics segment with one mature commercial franchise and a rare-disease pipeline expansion. The model depends on the LINZESS collaboration's shared sales and cost structure and on confirmatory clinical and regulatory progress for apraglutide.

Ownership
Institutions and insiders are filed separately and overlap, so together they can pass the whole company. No split is drawn from them.
Shares outstanding 164.61M · Float —
Float — provider float is below the insider stake.
A Form 4 total here can count shares the filer formally disclaims — an award voted by proxy, for instance — which the holder's own Schedule 13D/G excludes, so where the two disagree the schedule's smaller figure is used.
The provider's float is smaller than the insider stake it should exclude, so it is not shown.
