This is a single-center, open-label, single-sequence, crossover, drug-drug interaction study in healthy subjects.~Primary Objectives:~Safety~- To evaluate the safety of a single dose of INX-08189 (50 mg) alone and combined with verapamil HCL ER (240 mg) after subjects receive verapamil HCL ER QD for 6 days~Pharmacokinetic~- To evaluate the effect of multiple doses of verapamil HCL ER (240 mg) on the pharmacokinetic (PK) profile of INX-08189 and the metabolite INX-08032, and the effect of a single dose of INX-08189 on the PK profile of verapamil and the metabolite norverapamil
The purpose of this study is to evaluate the potential for a pharmacokinetic (PK) drug-drug interaction between INX-08189 and extended release verapamil hydrochloride (verapamil HCL ER).
