Aficamten and Patient-Reported Outcomes in Real-World nHCM (CAMPHOR-HCM)

September 23, 2026 updated by: Second Affiliated Hospital, Zhejiang University, School of Medicine

Comprehensive Aficamten Management and Patient-reported Health Outcomes in Real-world nHCM

This multicenter, prospective, observational, real-world clinical study aims to evaluate the efficacy and safety of Aficamten in patients with symptomatic non-obstructive hypertrophic cardiomyopathy (nHCM) by prospectively observing changes in symptoms, biomarkers, imaging findings, and adverse reactions, etc. It will also record the dosing regimens at which individual patients achieve steady state, and explore the treatment patterns of Aficamten in Chinese patients with symptomatic nHCM.

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.

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

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
Time Frame
Percentage change from baseline in NT-proBNP and/or absolute change from baseline in KCCQ-CSS
Time Frame: From enrollment to the end of treatment at 24 months
From enrollment to the end of treatment at 24 months

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.
Outcome Measure
Time Frame
Absolute change from baseline in NT-proBNP
Time Frame: From enrollment to the end of treatment at 24 months

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
