Parabilis Medicines, Inc. (PBLS) has started a dose-ranging cohort for its drug candidate zolucatetide in patients with familial adenomatous polyposis (FAP) as part of an ongoing Phase 1/2 clinical study. The decision follows early observations showing a reduction in duodenal polyp burden in two FAP patients, along with a favorable safety profile observed so far.

The trial expansion marks progress toward establishing a registrational dose for FAP, a disease currently lacking approved systemic therapies. Despite the clinical update, shares of Parabilis Medicines fell 7.25% to $26.85 during today's trading.

Investors will be watching for further updates from the company's clinical pipeline. Additional data across FAP and desmoid tumor cohorts are expected in the first quarter of 2027, alongside plans for a Phase 3 study in desmoid tumors.
