Summary

his is a single-center, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effect of Henagliflozin (an SGLT2 inhibitor) on myocardial fibrosis burden in patients with non-obstructive hypertrophic cardiomyopathy (nHCM). The study will use 68 68 Ga/ 18 18 F-FAPI PET/CMR imaging to quantitatively assess changes in active fibroblast activity after 6 months of treatment. A total of 150 eligible adult patients with nHCM (FAPI-positive at baseline, NYHA class I-III) will be enrolled and randomized in a 1:1 ratio to either the Henagliflozin group (10 mg once daily) or the placebo group for a 6-month treatment period. The primary endpoint is the change in myocardial FAPI target-to-background ratio (ΔTBR) at 6 months. Secondary endpoints include changes in FAPI SUVmax, FAPI burden percentage (FAV%), cardiac structure and function parameters, 6-minute walk distance, NYHA classification, NT-proBNP levels, and quality-of-life scores. Exploratory analyses will assess clinical events over 12 months, such as heart failure hospitalization, atrial fibrillation, ventricular arrhythmias, and cardiovascular death. The study employs stratified block randomization based on baseline FAPI burden, central randomization and blinding via IWRS, independent core laboratory imaging evaluation, and an intention-to-treat analytical approach. It aims to provide early evidence for the anti-fibrotic effect of Henagliflozin in nHCM and to validate FAPI-PET/CMR as an imaging biomarker for fibrosis activity.

Conditions

  • HCM - Hypertrophic Cardiomyopathy

Interventions

DRUG

Henagliflozin (SGLT2 Inhibitor)

This intervention involves the oral administration of Henagliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, at a dose of 10 mg once daily for a period of 6 months. Henagliflozin is provided as a film-coated tablet identical in appearance to the matched placebo used in the control arm. The intervention is administered in a double-blind manner as an add-on to stable standard background therapy for non-obstructive hypertrophic cardiomyopathy. This study specifically investigates the potential anti-fibrotic effects of Henagliflozin on active myocardial fibrosis, as quantified by novel FAPI PET/CMR imaging, in a patient population without diabetes mellitus.

DRUG

Placebo

This intervention involves the oral administration of a matched placebo tablet once daily for a period of 6 months. The placebo is manufactured to be identical in appearance (size, shape, color, coating), packaging, and administration schedule to the active comparator, Henagliflozin 10 mg tablet. It contains no active pharmaceutical ingredient. The intervention is administered in a double-blind manner as an add-on to stable standard background therapy for non-obstructive hypertrophic cardiomyopathy, serving as the control to isolate and evaluate the specific pharmacological effects of the SGLT2 inhibitor.
