Overview

The purpose of this study is to determine the superiority of the effectiveness of Henagliflozin 10 milligram (mg) daily versus blank control in participants with type II diabetes (T2DM) and symptomatic heart failure (HF) in improving the overall Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Summary Score (CSS).

Eligibility

Inclusion Criteria:
