Enavogliflozin for the Management of Patients With Amyloid CardiomyopaThy

Официальное название

Enavogliflozin for the Management of Patients With Amyloid CardiomyopaThy - A Randomized, Double-Blind, Placebo-Controlled, Crossover, Multicenter Trial

Обзор

This study aims to evaluate the safety and effectiveness of Enavogliflozin 0.3 mg, an SGLT2 inhibitor, in patients with amyloid cardiomyopathy. Participants will take both the study drug and a placebo in two separate periods, with a wash-out period in between. The goal is to determine whether Enavogliflozin is safe and effective for treating amyloid cardiomyopathy.

Подробное описание

Patients with a confirmed diagnosis of cardiac amyloidosis and symptomatic heart failure (NYHA class II-III) will be recruited.

Participants will be randomized to receive either the study drug or placebo and will undergo baseline and 12-week assessments, including the Kansas City Cardiomyopathy Questionnaire (KCCQ), 6-minute walk test, and cardiopulmonary exercise testing. Following a 4-week washout period, participants will cross over to the alternate treatment arm (study drug or placebo) and repeat the same assessments at baseline and 12 weeks.

The primary endpoint will be the change in KCCQ Clinical Summary Score (KCCQ-CSS).

Вмешательства

• Препарат Enavogliflozin 0.3mg
  Participants will receive Enavogliflozin 0.3 mg orally once daily for 12 weeks. The drug is administered in tablet form and is taken during the first or second treatment period of a crossover design.
• Препарат Placebo
  Participants will receive placebo orally once daily for 12 weeks. The drug is administered in tablet form and is taken during the first or second treatment period of a crossover design.

Первичные конечные точки

• Change in KCCQ-CSS from baseline to Week 12 [Срок оценки: Baseline and Week 12]

Вторичные конечные точки (6)

• Change in 6-Minute Walk Distance [Срок оценки: Baseline and Week 12]
• Change in log-transformed NT-proBNP levels [Срок оценки: Baseline and Week 12]
• Change in Body Weight [Срок оценки: Baseline and Week 12]
• Change in Body Fat Percentage [Срок оценки: Baseline and Week 12]
• Change in Extracellular Water Ratio [Срок оценки: Baseline and Week 12]
• Incidence of Worsening Heart Failure Events or Death [Срок оценки: From baseline to Week 12 during each treatment period (excluding the 4-week washout period)]

Критерии участия

Критерии включения

• Adults aged 19 years or older
• Diagnosed with amyloid cardiomyopathy confirmed by cardiac biopsy or non-invasive imaging
• Presence of heart failure symptoms corresponding to NYHA functional class II-III
