Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

The observational study will include adult patients with symptomatic obstructive hypertrophic cardiomyopathy (oHCM) who are enrolled in the Bristol Myers Squibb (BMS)-sponsored CAMZYOS Patient Support Program and who have initiated mavacamten as part of routine clinical care in Canada.

Description

Inclusion Criteria:

  • Patients who have initiated mavacamten, as part of routine clinical care, through the Bristol Myers Squibb CAMZYOS Patient Support Program for the treatment of symptomatic obstructive hypertrophic cardiomyopathy (oHCM)
  • Adult patient (≥18 years of age or as defined per local province/territory) at Index Date (first prescribed dose of mavacamten).
  • Patient has been diagnosed with symptomatic oHCM of New York Heart Association (NYHA) class II to III at the time of mavacamten initiation.

Exclusion Criteria:

  • In the 6 weeks prior to baseline (i.e., Index Date; date of first prescribed dose of mavacamten), patient has received any cardiac myosin inhibitor (including mavacamten) for oHCM or any other medical condition as part of a clinical trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in New York Heart Association (NYHA) functional class following mavacamten treatment initiation
Time Frame: Up to 1.5 years
  • Proportion of patients in each New York Heart Association (NYHA) functional class following mavacamten treatment initiation
  • Proportion of patients with a reduction of ≥1 New York Heart Association (NYHA) functional class following mavacamten treatment initiation
Up to 1.5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
