Study to Evaluate the Effect of Solifenacin and Mirabegron on the Tamsulosin Hydrochloride (HCl) Concentrations in Blood in Healthy Male Subjects
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the effect of solifenacin and mirabegron on the concentrations of tamsulosin HCl after combined dosing. This study will also evaluate the safety and tolerability of the combined administration of solifenacin, mirabegron and tamsulosin HCl.

Detailed Description
This study is comprised of two study sequences with 2 investigational periods in each sequence. There will be a wash-out period between each investigational period. Patients will be admitted to the clinic until discharged after each investigational period.

Eligibility Criteria
Criteria
Inclusion Criteria:

Subject and their female spouse/partners who are of childbearing potential must be using a highly effective form of contraception consisting of 2 forms of birth control (one of which must be a barrier method) starting at screening and continue throughout the clinical study period and for 90 days after the final study drug administration.
-
Subject must not donate sperm starting at screening and throughout the clinical study period and for 90 days after the final study drug administration.
-
Subject agrees not to participate in another interventional study while participation in the present clinical study, defined as signing the informed consent form until completion of the last clinical study visit.
Exclusion Criteria:
-
Subject has a known or suspected hypersensitivity to solifenacin succinate, mirabegron, tamsulosin HCl or any components of the formulations used including sulfa allergies.
-
Subject has any of the liver function tests (aspartate aminotransferase [AST], alanine aminotransferase [ALT], alkaline phosphatase, gamma-glutamyl transferase and/or total bilirubin [TBL]) above 1.5 of the upper limit of normal (ULN). In such a case the assessment may be repeated once [day-1].
