Heart Failure Research

With heart failure, the heart becomes incapable of pumping enough blood to meet the needs of the entire body. This condition affects millions of Americans and can limit how much ordinary physical activity people can perform. Despite long-term trends, recent data shows that the rate of heart failure is on the rise for many Americans. Clinical research is needed to address this growing concern. 

Jacksonville Center for Clinical Research is conducting a research study for volunteers to evaluate an investigational medication for people with Heart Failure and a reduced ejection fraction. 

 You may be eligible to participate if you: 

  • Are 18+ years old 
  • Have symptoms of heart failure 
    • Shortness of breath 
    • Fatigue 
    • Chest pain 
  • Have an Ejection Fraction (LVEF) less than 50% 
  • Have been on stable ACE inhibitor, ARB medication, or Entresto for at least 1 month 

There are additional criteria to meet to qualify for this study. Volunteers who qualify for our study will receive study-related medication and medical exams at no cost, along with a stipend for time and travel. No health insurance is required to participate.

Heart Failure Clinical Research

Heart failure is a serious medical condition where the heart cannot effectively deliver enough oxygenated blood to the organs. It affects millions of Americans and may have debilitating symptoms including edema, shortness of breath, systemic inflammation, and reduced quality of life. Even with the best available treatment, there is still a risk of serious complications. Reducing the amount of systemic inflammation may increase health outcomes for people with heart failure. We are conducting a research study for people with heart failure that will evaluate the effectiveness of an investigational drug on cardiovascular health outcomes.

You may be eligible if you:

  • Are 18 or older
  • Have heart failure
  • Have a preserved or mildly reduced ejection fraction (LVEF >40%) documented by echocardiography within the past 12 months

There are additional criteria to meet to qualify for this study. Volunteers who qualify for our study will receive study-related medication and study-related medical exams at no cost and a stipend for time and travel. No health insurance is required to participate.

Obesity needs a solution

Obesity is a chronic and complex disease associated with many serious health issues. Currently, there are over 600 million adults living with obesity.

Lifestyle changes are recommended as a first option for weight management, including diet changes, increased exercise, and behavioral therapy. However, these recommendations are not always successful, and people still struggle with weight management, even after making changes in their lifestyle.

That’s why we’re researching new ways to support weight management.

Thanks to people, like you, who have volunteered to make a difference and participate in clinical trials, there are now over 20,000 modern medicines that doctors can prescribe today. With your participation, we can help fight obesity.

Who can take part in this clinical trial?
• 18-74 years of age
• BMI of 30 or more
• Do not have diabetes
