EXPLORER-HCM: Mavacamten improves exercise capacity and functional class in patients with obstructive hypertrophic cardiomyopathy (HCM)

Watch Dr Martin Maron and Dr Iacopo Olivotto as they discuss key findings from the phase 3 EXPLORER-HCM trial which looks at the treatment effect of first-in-class cardiac myosin inhibitor, mavacamten, in patients with symptomatic obstructive HCM.

Topic

EXPLORER-HCM is a multicenter, phase 3, randomized, double-blind, placebo-controlled trial to investigate the safety and efficacy of the first targeted pharmacological therapy designed specifically to address the primary underlying pathophysiological basis of obstructive hypertrophic cardiomyopathy.

This 30-minute journal club explored the insights and impact of how the results of this pivotal trial supports a role for disease-specific therapy for obstructive HCM which treats the cause instead of just managing symptoms. The results of the global, phase 3 EXPLORER-HCM trial were presented at the European Society of Cardiology (ESC) Congress 2020 and simultaneously published in The Lancet.

Target audience

This educational activity is designed for cardiologists, cardiac surgeons, general physicians, cardiac nurses, and any other healthcare professional with an interest in HCM patients or cardiology.

Learning objectives

  • Discuss the current strengths and limitations of current medical and invasive septal reduction therapies for obstructive HCM and apply that information to a patient case
  • Recall the efficacy and safety data of the myosin inhibitor reported in the EXPLORER-HCM trial for adults with symptomatic obstructive HCM
  • Describe how myosin inhibitors were used in the treatment of obstructive HCM in the EXPLORER-HCM trial

Introduction to Heart Education USA’s first Journal Club

Listen to Dr Martin Maron open up Heart Education USA’s first journal club and the key objectives of the webinar.

EXPLORER-HCM: Mavacamten improves exercise capacity and functional class in patients with obstructive hypertrophic cardiomyopathy (HCM)

Watch Dr Iacopo Olivotto discuss the treatment of obstructive HCM in the EXPLORER-HCM trial.

Mavacatmen: mode of action and EXPLORER-HCM trial

In this video, Dr Olivotto talks about the mode of action of mavacamten in patients with symptomatic obstructive HCM and the key findings from the EXPLORER-HCM trial.

Q&A

Listen to Dr Maron and Dr Olivotto discuss questions submitted directly live from the audience. Featured questions include:

  • Does mavacamten have an impact on myocardial relaxation priorities?
  • Is there role for this drug in heart failure for preserved ejection fraction which extends beyond HCM?
  • Is there an effect with mavacamten on myocardial fibrosis?
  • Is there any evidence that mavacamten has an impact on sudden death risk in HCM?
