COLLIGO-HCM: A Multinational Observational Study of the Real-World Effectiveness of Mavacamten Among Patients With Symptomatic Obstructive Hypertrophic Cardiomyopathy (oHCM)

Active, not recruiting
Conditions
Hypertrophic Cardiomyopathy (HCM)
Interventions
Drug: Approved Hypertrophic Cardiomyopathy drug treatments
Registration Number
NCT06372457
Lead Sponsor
Bristol-Myers Squibb
Brief Summary

COLLIGO-HCM is a global observational study that will conduct observational research of hypertrophic cardiomyopathy (HCM) treatment in real-world clinical practice.

Detailed Description

The mavaCamten ObservationaL evIdence Global cOnsortium in hypertrophic cardiomyopathy (COLLIGO-HCM) is a global observational research initiative aiming to describe the real-world outcomes of treatments for obstructive hypertrophic cardiomyopathy (HCM), including mavacamten.

This retrospective study uses data from existing medical records and electronic registries from HCM centers around the world.

Inclusion Criteria
  • Source Cohort

    • Have at least one recorded encounter with a Hypertrophic Cardiomyopathy (HCM) diagnosis during or after 2018 (the first is defined as the index) and aged ≥18 years on the index date.

    • Disease-specific patient history documented in the medical record.
