• Status: Withdrawn
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The multi-centric, open label, single arm and self controlled study is planned to assess the efficacy of orally administered Sigmart in subjects with recurrent angina after coronary revascularization. The primary objective of this study is to demonstrate that orally administered Sigmart can improve the major Exercise Tolerance Test (ETT) result in recurrent angina subjects.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Merck KGaA; Merck KGaA, Darmstadt, Germany
• Treatments: Nicorandil
