About this study
Official title: Vitaccess Real MG Registry: A Prospective International Observational Patient Registry in Myasthenia Gravis Linking Clinical and Patient-reported Data.
Vitaccess Real MG (VRMG) is a patient registry designed to capture longitudinal observational data on myasthenia gravis (MG), its treatment, and impact on symptoms, daily activities, and quality of life (QoL). The duration of the registry is 10 years from launch, and approximately 600 patients will be recruited in the US and Europe with no defined upper limit. The registry will link relevant patient- and healthcare professional (HCP)-reported data with clinical data from medical records.
Patients will be recruited at clinical sites in all participating countries. In the US only, patients can additionally be recruited via community neurologists or direct-to-patient recruitment.
Read the detailed description
Traditional site recruitment (all countries):
Adult patients who are being treated for MG at one of the participating clinics or centers in one of the participating countries (currently the US and UK) at the time of enrolment and who meet the inclusion and exclusion criteria will be identified and approached by their clinical team and invited to participate in the registry.
Patient-reported data will be collected via the VRMG Registry platform, a digital data capture platform accessible via any web-enabled platform (e.g., phone, tablet, laptop, computer). Custom survey and patient-reported outcomes data will be collected at baseline and at regular intervals thereafter for a follow-up period of up to 10 years. The data collected will capture the impact of MG on daily living, fatigue, and health-related quality of life.
Site research teams will complete and update an eCRF (every six months ± one months) for each patient, including data from the patient's EMR. eCRFs that are completed within one months prior to or following each six-month mark will be considered within the same assessment window for analytics purposes so that patients will not be required to visit the clinical site for the purposes of the registry outside of their regular clinical visits.
Community neurologist recruitment (US only):
Community neurologists who are treating MG patients who would be eligible for participation in the registry will be able to register their interest for involvement and provide details of their credentials via an informational website. Approved community neurologists will identify and approach potential participants, who will participate in the registry as normal. Clinical data will be captured from participants' electronic medical records via an EMR aggregator.
Direct-to-patient recruitment (US only):
A cohort of US-based participants in the MyRealWorld MG study - a longitudinal observational study in MG that Vitaccess has run since 2019 - have provided consent to be contacted by Vitaccess about future research. Vitaccess will contact this patient cohort directly via email to introduce them to the registry; patients can access the registry's informational website to get further information. Clinical data will be captured from participants' electronic medical records via an EMR aggregator.
Patient-reported and eCRF data will be linked via a unique ID and PIN assigned to each participant at enrolment.

Clinical summary

Questions about this trial
What is this clinical trial studying?
An observational study of Myasthenia Gravis, run by Vitaccess Ltd at 8 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 29 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mark JW Larkin, PhD (+44 1865818983, mark.larkin@vitaccess.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Vitaccess Real MG Registry (time frame: 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2025; AzTrials last refreshed its copy on 27 Oct 2026.
