Immediate Release Versus Slow Release Carvedilol in Heart Failure

Phase 4
Conditions
Heart Failure With Reduced Ejection Fraction
Interventions
Drug: CarVeDilol-SR (Slow Release)
Registration Number
NCT03209180
Lead Sponsor
Seoul National University Bundang Hospital
Brief Summary

Assessment of clinical effect and treatment quality of immediate release carvedilol (IR) versus slow release carvedilol (SR) in patients with HFrEF

Detailed Description

The SLOW-HF trial is a phase 4, randomized, open label, multicenter study to evaluate the therapeutic efficacy of carvedilol-SR compared to carvedilol-IR in patients with heart failure with reduced ejection fraction. Patients with stable HFrEF will be randomly assigned (1:1) to carvedilol SR group (160 patients) and carvedilol IR group (160 patients).

After randomization, patients will be followed for 6 months. The primary endpoint is the change in NT-proBNP level from baseline to the study end. The secondary endpoints include the frequency of NT-proBNP increment \>10% from baseline, composite of all-cause mortality and readmission, mortality rate, readmission rate, changes in blood pressure, quality of life, and drug compliance.

  16. Malignant disease including lymphoma and leukemia within 5 years

  17. Patients who were prescribed other medication for any clinical trials pre-analytical within 28 days

  18. Patients who are predicted to have prolonged hospital days due to other medical problems other than chronic heart failure (for example, femur neck fracture)

  19. Patients who are considered as inappropriate to participate in the clinical trial by testers
