Summary

The objective of this study is to investigate the efficacy and safety of Pletaal (Cilostazol) in comparison with placebo for 4 weeks in vasospastic angina patients who have an insufficient response to Amlodipine (Calcium channel blocker).

Clinical Details

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Therapeutic Exploratory Study to Evaluate the Efficacy and Safety of Pletaal“(Cilostazol) in Subjects With Vasospastic Angina (STELLA)

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Percent change of the chest pain frequency

Secondary outcome: The chest pain frequency, the pain intensity, nitroglycerin consumption of the final a week after IP dosing from a week before IP dosing

Detailed description: A Multicenter, Randomized, Double-Blind, Placebo-controlled, Parallel group, Therapeutic exploratory Study. The subject who has at least an episode of chest pain weekly despite Amlodipine 5mg once a day (qd) taking during 2 weeks will have treatment of Pletaal (Cilostazol) or Placebo for 4 weeks. Pletaal (Cilostazol) is taken 100mg oral tablets two times a day (bid) during 2 weeks after dosing of Pletaal (Cilostazol) 50mg oral tablets bid during 2 weeks. Placebo of Pletaal (Cilostazol) is used as the control medication.
