Clinical trials

Many patients with Crohn's disease (CD) develop fibrotic narrowing (strictures) in their bowel, causing obstructive symptoms such as abdominal pain, cramping, or vomiting after meals. Because of these symptoms, patients often require bowel resection surgery. The objective of this clinical trial is to evaluate the efficacy, safety, and dose-response relationship of ontunisertib in participants with CD and symptomatic strictures, and contribute to the validation of novel endpoints to assess potential treatment benefit in patients with fibrostenosing Crohn's disease (FSCD). The participants will be in the trial for a duration of up to 60 weeks, consisting of a 6-week screening period (with 2 screening visits), a 52-week treatment period, and a 2-week follow-up period. The visit frequency in the treatment period will be every 6 to 8 weeks.

This is an open, two-part study in healthy male volunteers, aged 30-65 years. This trial aims to understand how the human body absorbs, distributes, metabolizes and eliminates ontunisertib after a single oral dose of radiolabelled test medicine (\[14C\]ontunisertib) and determine the routes and rates of elimination of the test medicine.
