Summary

This trial aims to study the safety and effectiveness of genistein in patients with a condition called Transthyretin (TTR) Amyloidosis. The focus is on how genistein

Who is the study for?
This trial is for patients with Transthyretin (TTR) Amyloidosis, specifically affecting the heart. Participants should be able to provide consent and follow the study's procedures, including blood tests, echocardiography, and a walking test. Detailed inclusion and exclusion criteria are not provided.
What is being tested?
The trial is testing genistein's safety and effectiveness in TTR Amyloidosis patients. It involves taking increasing doses of genistein orally over 12 weeks followed by a six-week washout period. The study will measure changes in inflammation markers, cardiac function, and exercise capacity.
What are the potential side effects?
Potential side effects of genistein are not detailed here but may include typical drug-related reactions such as gastrointestinal discomfort or allergic responses. Close monitoring through blood tests aims to ensure patient safety.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Genistein Treatment and WashoutExperimental Treatment1 Intervention
The Investigators plan to recruit 40 heart failure participants, including 20 participants with heart failure with reduced ejection fraction (LVEF\<40%) and 20 participants with transthyretin amyloid (ATTR) cardiomyopathy. After an initial telephone call to screen participants, the Investigators will invite qualified people for informed consent and a baseline fasting blood draw. Participants will receive escalating doses of genistein after their baseline fasting blood and stool sample collections. At baseline and again at 3 months, the Investigators will also perform transthoracic echocardiography and a 6-minute walk test.
