Hypertrophic Cardiomyopathy (HCM)CAMPHOR-HCMNCT07846176
Aficamten and Patient-Reported Outcomes in Real-World nHCM
An observational study of Hypertrophic Cardiomyopathy (HCM), run by Second Affiliated Hospital, Zhejiang University, School of Medicine.
Trial summary
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. Read more about this study

About this study
Official title: 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
- Hypertrophic Cardiomyopathy (HCM)
- Being tested
- receiving aficamten
- Keywords
- non obstructive hypertrophic cardiomyopathy, aficamten
- Medical subject headings
- Cardiomyopathy, Hypertrophic
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
receiving aficamtenDrug
Aficamten will be administered at a specified dose according to each patient's tolerability, as assessed by echocardiography.
| Study group | Role | What they receive |
|---|---|---|
| Aficamten group | Patients with non-obstructive hypertrophic cardiomyopathy (nHCM) receiving aficamten therapy Receives: Drug: receiving aficamten |
