How to Join CMT Clinical Trials and Patient Registries

To join Charcot-Marie-Tooth (CMT) disease clinical trials, the most effective first step is to sign up for an official patient contact registry. Registries are secure databases that connect patients with researchers. By sharing your medical profile in these registries, you will be directly notified when an active clinical trial or research study opens that matches your specific type of CMT. The three primary organizations you should register with via their official websites are the Inherited Neuropathies Consortium (INC), the CMT Association (CMTA), and the Hereditary Neuropathy Foundation (HNF).

Understanding Patient Registries

A patient registry is a secure collection of health information from people who have a specific disease. Participation in a patient registry is an essential foundational step that allows researchers to contact you for future research opportunities ^[1]. This is different from directly enrolling in a clinical trial, which is an active study testing a specific experimental treatment ^[2].

Because CMT is a rare disease with many different genetic subtypes, finding enough eligible patients for a study is often one of the biggest challenges for researchers. Patient registries serve as critical infrastructure, creating a ready group of patients who can be quickly recruited into new studies ^[3]. Registries also collect patient-reported outcomes—information about how you feel and function in your daily life—which gives researchers a long-term perspective on the daily burden of the disease ^[4].

The Three Main CMT Registries

To maximize your chances of finding a trial, it is highly recommended to join the major CMT registries. They are patient-led and work together to support the CMT community ^[1]. You can find sign-up information on each organization’s official website:

• Inherited Neuropathies Consortium (INC) Registry: The INC is an international group of clinical researchers dedicated to CMT. Joining their registry places you in a cohort of patients who are available for recruitment into upcoming clinical studies ^[5].
• CMTA Patients as Partners in Research: Maintained by the CMT Association (CMTA), this registry (previously known as CMTA-STAR) informs patients about ongoing studies and helps connect the community directly with scientific research ^[2].
• Global Registry for Inherited Neuropathies (GRIN): Run by the Hereditary Neuropathy Foundation (HNF), GRIN collects long-term data on patients and plays a major role in matching individuals with appropriate clinical trials ^[4].

Types of Research Studies

When you join a registry, you may be contacted for two main types of research:

1. Natural History Studies (Observational)

In these studies, researchers observe you over time without giving you any new treatment. Natural history studies are essential for defining biomarkers (biological signs of the disease) and determining how to measure the disease’s progression ^[3]. Having these measurable outcomes is an absolutely necessary foundation before interventional trials can be successfully designed and launched ^[6].

2. Interventional Clinical Trials

These are studies where you participate directly in testing the safety and effectiveness of a new therapy. This includes Phase I trials (testing safety and dosage in a small group), as well as Phase II and Phase III trials (testing effectiveness and monitoring side effects in larger groups) ^[7]. Participation may require travel to specific research centers, though travel expenses are sometimes covered by the study sponsors.

How to Prepare for Enrollment

While you wait for trial matches through the registries, there are practical steps you can take:

• Confirm Your Genetic Diagnosis: Because interventional trials are often targeted at specific gene mutations (like CMT1A or CMTX), having a confirmed genetic test result is usually required to participate. If you do not have a confirmed diagnosis, ask your neurologist about genetic testing or a referral to a genetic counselor.
• Keep Your Records Updated: Have a copy of your genetic test results and your most recent clinical notes from your neurologist ready to upload to the registries.
• Consult Your Care Team: Before committing to any trial, discuss the potential risks, benefits, and specific inclusion/exclusion criteria with your primary neurologist.
• Search Actively on ClinicalTrials.gov: You do not have to wait for an email to find opportunities ^[1]. While ClinicalTrials.gov can be overwhelming to navigate, you can start by searching “Charcot-Marie-Tooth” and applying the “Recruiting” filter to find active studies. Advocacy organizations like the CMTA and HNF also curate user-friendly lists of active trials on their websites.
