A Prospective Registry Study to Assess Real-world Patient Characteristics, Treatment Patterns, and Longitudinal Outcomes in Patients Receiving Mavacamten and Other Treatments for Symptomatic Obstructive Hypertrophic Cardiomyopathy (Obstructive-HCM)

Recruiting
Conditions
Obstructive Hypertrophic Cardiomyopathy
Interventions
Drug: Non-mavacamten symptomatic oHCM therapy
Registration Number
NCT05489705
Lead Sponsor
Bristol-Myers Squibb
Brief Summary

This registry evaluates patient characteristics, real-world treatment patterns, and short- and long-term outcomes in a population of patients in the United States and Europe with symptomatic obstructive hypertrophic cardiomyopathy (HCM) who are receiving mavacamten, receiving other treatment for obstructive HCM, or not receiving treatment for obstructive HCM due to intolerance or failure of prior treatment.

United States Sub-Study: The purpose of this study is to evaluate the safety of mavacamten in patients with symptomatic obstructive HCM in the real-world setting.

Europe Sub-Study: The purpose of this study is to evaluate the effectiveness and safety of mavacamten in patients with symptomatic obstructive HCM in the real-world setting.

Primary Outcome Measures
NameTimeMethod
Change in resting left ventricular outflow tract (LVOT) gradient from baselineUp to 18 months

European Participants only

Incidence rate of new or worsening heart failure due to systolic dysfunction among participants with symptomatic obstructive HCM during periods of exposure to mavacamten and other oHCM treatmentUp to 5 Years

Systolic dysfunction defined as symptomatic Left Ventricular Ejection Fraction (LVEF) \< 50%. United States participants only.

Secondary Outcome Measures
NameTimeMethod
New or worsening heart failure due to systolic dysfunctionBaseline and up to 18 months

Symptomatic left ventricular ejection fraction (LVEF) \<50%. European Participants only

Proportion of participants with a resting or provoked peak left ventricular outflow tract (LVOT) gradient below 50 mmHGBaseline and up to 18 months

European participants only

Evaluation of patient reported outcome measure: Kansas City Cardiomyopathy Questionnaire 23 (KCCQ-23)Baseline, and up to 5 Years

The KCCQ-23 is a disease-specific health status instrument composed of 23 items that quantifies the domains of physical limitations, symptoms, self-efficacy, social limitation and quality of life from heart failure. Scores range from 0-100, in which higher scores reflect better health status. United States participants only

Evaluation of patient reported outcome measure: EuroQol Five Dimensions Questionnaire (5-level) (EQ-5D-5L): Health Utility IndexBaseline, and up to 5 Years

The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L health utility index and EQ Visual Analog Scale (VAS). EQ-5D-5L health utility index is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participants select an answer for each of the 5 dimensions that best matches his/her health "today". Responses are used to generate a weighted summary index, which ranges from 0 to 1.00. A higher score indicates better health and positive changes from baseline indicate improvement of health. United States participants only

Evaluation of patient reported outcome measure: EQ-5D-5L: VASBaseline, and up to 5 Years

The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and VAS.

The VAS self-rating records the participant's own assessment of his or her overall health status at the time of completion, on a vertical line VAS with scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine). A higher score indicates better health and positive changes from baseline indicate improvement of health status. United States participants only

Occurrence of arrhythmiaBaseline, and up to 18 months (European participants), or 5 Years (United States participants)

Incidence rates of participants with arrhythmia (new onset)

Occurrence of non-fatal acute Myocardial Infarction (MI)Up to 5 Years

United States participants only

Occurrence of all-cause mortalityBaseline, and up to 18 months (European participants), or 5 Years (United States participants)
Evaluation of biomarkers of response: Cardiac troponinBaseline, and up to 5 Years

Change From Baseline in Serum Concentration of Cardiac Troponins. United States participants only

Proportion of participants with a resting or provoked peak left ventricular outflow tract (LVOT) gradient below 30 mmHGBaseline and up to 18 months

European participants only

Occurrence of Major Adverse Cardiovascular Events (MACE)Up to 5 Years

A composite endpoint consisting of non-fatal acute Myocardial Infarction (MI), stroke, hospitalization due to Heart Failure (HF) and Cardiovascular (CV) mortality. United States participants only.

Occurrence of StrokeUp to 5 Years

United States participants only

Occurrence of hospitalization due to heart failureBaseline, and up to 18 months (European participants), or 5 Years (United States participants)
Occurrence of cardiovascular mortalityUp to 5 Years

United States participants only

Evaluation of functional responses: New York Heart Association (NYHA) function classBaseline, and up to 18 months (European participants), or 5 Years (United States participants)

Percentage of Participants Whose NYHA Class Changes

Evaluation of functional responses: Left Ventricular Outflow Tract (LVOT) gradientBaseline, and up to 18 months (European participants), or 5 Years (United States participants)

Mean Change From Baseline in LVOT Gradients At Rest and Provoked

Evaluation of functional responses: LVEFBaseline, and up to 18 months (European participants), or 5 Years (United States participants)

Mean Change from Baseline in LVEF

Evaluation of biomarkers of response: NT-proBNPBaseline, and up to 5 Years

Change From Baseline in Serum concentration of NT-proBNP. United States participants only
