Survival Study of the Recombinant Human Neuregulin-1β in Subjects With Chronic Heart Failure.

Phase 3

Recruiting

• Conditions: Chronic Heart Failure
• Interventions: Drug: Placebo; Drug: rhNRG-1

• Registration Number: NCT03388593
• Lead Sponsor: Zensun Sci. & Tech. Co., Ltd.

Brief Summary

The purpose of this study is to evaluate efficacy of rhNRG-1 in reducing the death rate of heart failure subjects with baseline NT-proBNP level between 600 pg/ml and 1700 pg/mL and NYHA class II to III.

Detailed Description

The mortality of chronic heart failure patients remains high, in spite of current treatment. RhNRG-1(recombinant human neuregulin-1)directly work on the cardiomyocyte and restored the normal structure and function of it. Both the preclinical trials, phase II clinical trials and already completed phase III clinical trails have confirmed that rhNRG-1 effectively enhance the heart function, reverse the remodeling of left ventricular, and reduce all-cause mortality in heart failure animals and humans. More importantly, rhNRG-1 can significantly reduce the mortality of heart failure subjects with baseline NT-proBNP level ≤1600 fmol/mL and NYHA class II to III. In this phase III study, the investigators will further confirm the efficacy of rhNRG-1 in reducing the death rate of heart failure subjects with baseline NT-proBNP level between 600 pg/ml and 1700 pg/mL and NYHA class II to III.

• 5. Diagnosed as chronic systolic heart failure (history, symptoms, signs), and in stable condition in the last one month.
• 6. Receiving standard therapy for chronic heart failure, reach target dose or max tolerable dose for one month, or has not changed the dose for one month before randomization.
• 7. Capable of signing the informed consent form.

Exclusion Criteria

• 1. New chronic heart failure patients, or patients receiving standard therapy on chronic heart failure for less than 3 months.
• 2. NYHA functional class I OR IV.
• 3. NT-proBNP < 600 pg/ml OR NT-proBNP>1700 pg/ml (by Roche assay Kit in central lab).

• 7. Unstable angina.
• 8. Patients with acute pulmonary edema or acute hemodynamic disorder.
• 9. Chronic heart failure patients with acute hemodynamic disorder or acute decompensation in the last 1 month (symptoms and signs suggest worsening chronic heart failure and may require intravenous drug therapy).
• 10. Patients with right heart failure caused by pulmonary disease.

• 25. Evidence (physical examination, chest X-ray (CXR), ECHO or other tests) shows some active malignancy or adenoidal hypertrophy or neoplasm that has an effect on heart function or the endocrine system, e.g., pheochromocytoma or hyperthyroidism (Thyroid nodules with normal thyroid function do not need to be excluded).
• 26. As judged by the investigator that the subject cannot complete the study or adhere to the study requirements (due to the management reasons or others).

rhNRG-1	rhNRG-1	rhNRG-1 in addition to standard therapy

Primary Outcome Measures

Name	Time	Method
All-cause mortality	1 year	Including deaths from cardiovascular and non-cardiovascular causes, Log-Rank test was used for comparison between groups, and Kaplan-Meier survival curves were plotted; COX proportional hazard model was used to estimate the HR and its 95% confidence interval.

Secondary Outcome Measures

Name	Time	Method
New York Heart Association (NYHA) functional classification	1 year	For the NYHA cardiac functional grading after administration, summarize the number and percentage of subjects by different study visit period, compare the efficacy differences among test groups and control groups. In addition, calculate the changes of NYHA cardiac functional grade from baseline of the subjects. The intragroup changes will be analyzed by signed-rank sum test, intergroup comparison will be conducted by Wilcoxon test.
Change of NT-proBNP level at the 25th week and 52th week	1 year	The paired t test or signed rank sum test was used to compare the changes before and after treatment in each group, and the comparison between groups was performed by analysis of variance or Wilcoxon rank sum test.
Percentage of all-cause re-hospitalization	1 year	The Kaplan-Meier curve was used to describe the cumulative incidence rate of the first re-hospitalization, and the differences between the two groups were compared using Log-Rank.
Percentage of Participants with re-hospitalization caused by worsening heart failure	1 year	The Kaplan-Meier curve was used to describe the cumulative incidence rate of the first re-hospitalization, and the differences between the two groups were compared using Log-Rank.
Mortality caused by cardiovascular events	1 year	Log-Rank test was used for comparison between groups, and Kaplan-Meier survival curves were plotted; COX proportional hazard model was used to estimate the HR and its 95% confidence interval.
All-cause mortality of female subjects	1 year	Log-Rank test was used for comparison between groups, and Kaplan-Meier survival curves were plotted; COX proportional hazard model was used to estimate the HR and its 95% confidence interval.
All-cause mortality of male subjects	1 year	Log-Rank test was used for comparison between groups, and Kaplan-Meier survival curves were plotted; COX proportional hazard model was used to estimate the HR and its 95% confidence interval.
