FORTITUDE-HCM

A Global Phase 2b Study of Ninerafaxstat in Non-Obstructive HCM (nHCM)

ABOUT FORTITUDE-HCM

FORTITUDE-HCM is a global clinical study evaluating whether ninerafaxstat, a new investigational drug, can help adults with symptomatic non-obstructive hypertrophic cardiomyopathy (nHCM) feel and function better in daily life.

In this study, participants will receive either ninerafaxstat or a placebo. A placebo looks like the study drug but has no active ingredients. Comparing the two helps researchers learn if ninerafaxstat can improve heart-related symptoms and quality of life.

To understand how well ninerafaxstat works, the study will measure things like:

  • Your cardiac symptoms and how these affect your everyday activities
  • Your ability to exercise (using a treadmill or bicycle up to your personal best)
  • The structure and function of your heart using a heart ultrasound (echocardiogram)
  • The amount of ninerafaxstat in your blood


These measurements help researchers learn whether the study drug makes a meaningful difference for people living with nHCM.

Who can join the study?

(Abbreviated Participation Criteria)

You may be able to take part if you:
  • Are 18 years or older
  • Have been diagnosed with hypertrophic cardiomyopathy (HCM)
  • Have a diagnosis of non-obstructive HCM (nHCM) confirmed by a heart ultrasound (echocardiogram)
  • Have symptoms related to your HCM


Additional requirements apply. Check full eligibility at ClinicalTrials.gov (NCT07023614).

WHAT IS FORTITUDE-HCM?

Clinical Trial Overview

FORTITUDE-HCM is a Phase 2b clinical trial studying whether ninerafaxstat, a new investigational drug, can improve symptoms, exercise capacity, and overall quality of life in adults with symptomatic nHCM.

In this study, participants are randomly assigned to take either ninerafaxstat or a placebo. Your chance of receiving either ninerafaxstat or placebo will be 1 in 2 (i.e. 50%). This helps ensure the study results are fair and unbiased.

Clinical Trial Duration

Participation in the study will last approximately 20 weeks. This includes screening, 12 weeks of treatment, and follow-up visits for all trial participants.

Clinical Trial Drug

If you qualify and join the study, you will receive ninerafaxstat (200 mg twice daily) or a placebo. You will continue your usual standard-of-care treatment during the study.

Clinical Trial Locations

FORTITUDE-HCM is enrolling participants at sites across the United States. View All Sites on ClinicalTrials.gov (NCT07023614).

ABOUT nHCM

Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thicker than normal, making it harder for the heart to pump blood effectively.

In non-obstructive HCM, or nHCM, the heart muscle is thickened but does not block blood flow out of the heart. Even without a blockage, the heart may not fill or relax the way it should.

People with nHCM may have symptoms such as:

  • Shortness of breath
  • Chest pain (angina)
  • Tiredness
  • Dizziness
  • A racing or irregular heartbeat (palpitations)

 

Symptoms vary and often get worse with physical activity. There are currently no approved treatments specifically for nHCM.
