Building Your Care Team and Exploring Treatments

At a Glance

Managing Becker Muscular Dystrophy (BMD) requires a proactive, multidisciplinary care team led by a neuromuscular specialist. Regular monitoring of the heart, lungs, and metabolism is essential, alongside exploring therapies like physical therapy and emerging clinical trials.

Managing Becker Muscular Dystrophy (BMD) requires a shift from reactive care—treating symptoms as they appear—to a proactive, multidisciplinary approach [1]. Because BMD is a lifelong condition that affects multiple systems, having a team that understands its specific nuances is essential for maintaining independence and quality of life.

Your Multidisciplinary Care Team

A “best-practice” team for BMD includes several specialists who work together to monitor different aspects of the condition:

  • Neuromuscular Specialist (Neurologist): The lead doctor who manages the primary muscle symptoms and coordinates the rest of the team [1].
  • Cardiologist: Focuses on the heart. Since heart issues can happen even if your muscles are strong, regular heart check-ups are critical [2][3].
  • Genetic Counselor: Helps you understand your specific genetic test results and explains the implications for female relatives (like sisters or daughters) who may be carriers [4].
  • Pulmonologist: Monitors lung function and breathing strength, particularly as you get older or if walking ability changes [5].
  • Physical and Occupational Therapists (PT/OT): Help you stay mobile and independent while teaching you safe ways to exercise and protect your muscles from overexertion.
  • Endocrinologist: Monitors for metabolic issues like glucose intolerance, which is more common in adults with BMD [6].
  • Neuropsychologist: Evaluates and treats cognitive or behavioral concerns, such as ADHD or working memory issues, which are frequent in BMD [7][8].

Standard Monitoring Schedule for Adults

While your doctor will tailor this to you, a typical annual “maintenance” plan for an adult with BMD often includes:

  • Cardiology: Annual EKG and imaging (Echocardiogram or, ideally, Cardiac MRI) [2][9].
  • Pulmonology: Annual pulmonary function tests (PFTs) to check breathing strength [5]. Note: For fully ambulatory patients with a history of normal breathing baselines, doctors may space these tests out less frequently.
  • Metabolic: Annual blood tests for glucose and insulin levels [6].
  • Musculoskeletal: Regular check-ins with a PT to assess walking speed and functional strength [1].
  • For Female Carriers: If you are a female carrier of the BMD gene, you should undergo a cardiac screening (EKG and echocardiogram or MRI) starting in early adulthood, and continue monitoring every 3-5 years [2][10].

Treatments: Current and Emerging

Corticosteroids in BMD

Unlike in Duchenne (DMD), where corticosteroids (like prednisone) are the standard of care to slow muscle decline, their use in BMD is much less common [11][12]. Because BMD progresses more slowly, doctors must carefully weigh the benefits of steroids against their long-term side effects, such as weight gain and bone loss [11].

The Clinical Trial Landscape

There is a growing focus on treatments designed specifically for the BMD population:

  • Sevasemten (EDG-5506): This is an investigational drug that aims to protect muscles by reducing the stress placed on fast-twitch muscle fibers during contraction [13][14]. Early studies have shown it is well-tolerated and may reduce markers of muscle injury in the blood [13].
  • Vamorolone: While primarily used in DMD as a “dissociative steroid” with fewer side effects, it has shown promise in preclinical BMD research, though large-scale human trials specifically for BMD are still developing [11][15].
  • MRI as a Biomarker: Researchers are increasingly using muscle MRI (fat fraction) to track disease progression [16]. This allows scientists to see how much muscle tissue is being replaced by fat, providing a more precise way to measure if a new drug is working [16][17].

Staying informed about these developments allows you to have more meaningful conversations with your care team about participating in research or adjusting your management plan as new options become available.

Common questions in this guide

Which doctors should be on my Becker Muscular Dystrophy care team?
A comprehensive BMD care team is typically led by a neuromuscular specialist and includes a cardiologist, pulmonologist, genetic counselor, endocrinologist, neuropsychologist, and physical and occupational therapists. This ensures all aspects of the condition are monitored proactively.
How often do adults with BMD need heart checks?
Adults with BMD should have an annual cardiology evaluation, typically including an EKG and an echocardiogram or cardiac MRI. Since heart issues can occur even if muscles are strong, regular monitoring is critical for long-term health.
Are corticosteroids used to treat Becker Muscular Dystrophy?
Corticosteroids are used much less frequently in BMD compared to Duchenne muscular dystrophy. Because BMD progresses more slowly, doctors carefully weigh the potential benefits against long-term side effects like weight gain and bone loss.
What new treatments are in clinical trials for BMD?
Emerging treatments specifically designed for BMD include Sevasemten (EDG-5506), an investigational drug that aims to protect fast-twitch muscle fibers from stress during contraction. Researchers are also exploring the use of vamorolone in BMD.
Do female carriers of the BMD gene need medical monitoring?
Yes, female carriers of the Becker Muscular Dystrophy gene should have regular cardiac screenings. This usually starts in early adulthood and includes an EKG and echocardiogram or MRI every three to five years.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.How many patients with Becker Muscular Dystrophy (specifically, not just Duchenne) do you currently manage?
  2. 2.Do you recommend a Cardiac MRI for tracking heart scarring, or do you only use standard echocardiograms?
  3. 3.Given the risk of glucose intolerance in adult BMD, how often will we be testing my insulin and blood sugar levels?
  4. 4.What is your opinion on the use of corticosteroids for BMD, and how does your approach differ from treating Duchenne?
  5. 5.Are there any clinical trials specifically for BMD, like the sevasemten (EDG-5506) study, that I might be eligible for?
