Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to evaluate the urodynamic variables of male subjects with LUTS and BOO treated with the co-administration of 6 mg solifenacin succinate and TOCAS, and 9 mg solifenacin succinate and tamsulosin OCAS versus placebo.;Secondary Objective: To evaluate the tolerability and safety of the co-administration of 2 doses of solifenacin succinate and tamsulosin OCAS in male subjects with LUTS and BOO. To compare the efficacy of the co-administration of 2 doses of solifenacin succinate and tamsulosin OCAS versus placebo in signs and symptoms of BPH in male subjects with LUTS and BOO ;Primary end point(s): The primary variables are urodynamic variables: - Change from baseline to end of treatment in detrusor pressure (Pdet) at maximum flow rate (Qmax) (PdetQmax) - Change from baseline to end of treatment in maximum flow rate (Qmax)
