Condition(s) targeted: Pharmacokinetics of Mirabegron and Tolterodine; Healthy

Intervention: tolterodine (Drug); mirabegron (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Astellas Pharma Inc

Official(s) and/or principal investigator(s):
Medical Director, Study Chair, Affiliation: Astellas Pharma Inc

Summary

To assess the effect of multiple doses of mirabegron to postmenopausal adult female subjects on the pharmacokinetics (PK) of tolterodine and its metabolites. In addition, the safety of these products will be assessed.

Clinical Details

Official title: Post-Marketing Study of Mirabegron - A Pharmacokinetic Study to Assess Drug-Drug Interaction Between Mirabegron and Tolterodine -

Study design: Endpoint Classification: Pharmacokinetics Study, Intervention Model: Single Group Assignment, Masking: Open Label

Primary outcome:

Plasma concentration of unchanged mirabegron

Plasma concentration of unchanged tolterodine

Secondary outcome:

Plasma concentration of tolterodine metabolites (5-hydroxymethyl tolterodine; 5-HMT)

Safety assessed by the incidence of adverse events, vital signs, clinical labo-tests, and 12-lead ECG
