A Safety and Pharmakokinetic Study of A4250 Alone or in Combination With A3384
March 6, 2024 updated by: Albireo
A Phase I, Double-Blind Single and Multiple Ascending Dose Study to Assess Safety and Pharmacokinetics of A4250 as Monotherapy, and in Combination With Colonic Release Cholestyramine (A3384) or Commercially Available Cholestyramine (Questran™) in Healthy Subjects
The primary objectives of the study are to evaluate the safety, tolerability and pharmacokinetics of A4250 after single or multiple oral doses in healthy subjects.
In addition, will evaluate A4250 in combination with cholestyramine.
