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

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.

Description

Inclusion Criteria:

  • Age 18-85 years.

  • Confirmed diagnosis of HCM:

    1. Left ventricular wall thickness ≥15 mm at any site on echocardiography or cardiac magnetic resonance.
    2. Left ventricular wall thickness ≥13 mm in individuals testing positive for a pathogenic variant or in genetically affected family members.
    3. Ventricular wall thickening caused by other cardiovascular diseases or systemic or metabolic disorders has been excluded.
  • Symptomatic nHCM patients meeting all of the following conditions:

    1. Left ventricular outflow tract gradient (LVOTG) <30 mmHg at rest and/or with provocation.
    2. Presence of any one of the following symptoms: fatigue (weakness), dyspnea, chest pain, palpitations, or syncope.
    3. New York Heart Association (NYHA) functional class II or III.
  • Left ventricular ejection fraction (LVEF) ≥60% as assessed by transthoracic echocardiography.

  • Signed and dated written informed consent, and willingness to return for clinical follow-up.

Exclusion Criteria:

  • LVOTG ≥30 mmHg at rest and/or with provocation.
  • LVEF <50% on transthoracic echocardiography.
  • Symptomatic hypotension or systolic blood pressure (SBP) <100 mmHg.
  • Severe renal impairment, estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m², or currently receiving blood purification therapy.
  • Planned implantable cardioverter-defibrillator (ICD) implantation or cardiac resynchronization therapy (CRT) within 3 months.
  • Women who are pregnant or planning to become pregnant during the trial.
  • Currently participating in another investigational device or drug trial.
  • Any other clinical condition with an expected survival of less than 2 years.
