Expediting Myasthenia Gravis (MG) Diagnostic Evaluation: A Novel, Proof-of-Concept for Undiagnosed, Symptomatic Patients That Uses Social Media Targeting and Self-Assessment

March 20, 2025 updated by: Ananda Vishnu Pandurangadu, MD, ZS Associates
This is a fully remote, site-less, prospective, observational study enrolling adults in the United States (excluding U.S. territories) with undiagnosed neuromuscular symptoms. The main study objective is to evaluate the feasibility of a social media recruitment campaign tied to a participant reported symptom survey and self-administered physical assessment tool to influence undiagnosed participants to seek care for suspected Myasthenia Gravis (MG).

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants with undiagnosed neuromuscular symptoms will be targeted via social media paid advertisements to recruit them to our study landing page (weblink: https://bit.ly/unearthrootcause). Two assessment tools were developed by the study team: the Impact of Daily Living (IDL) Survey and the MG Exercise Assessment. Both tools were designed using supporting literature, accepted guidelines, and a rigorous review via a panel of practicing neurologist key opinion leaders experienced in treating MG patients.

Adult participants who don't have specific diagnosed neurologic conditions will first be screened for eligibility based on the results of the IDL survey which will query participants on the presence or absence of habits/symptoms characteristic of MG. Those who qualify will complete the MG Exercise Assessment in which participants are provided video instructions to perform a series of 10 physical tests to examine if specific muscle groups undergo inducible fatigue. The results of the MG Exercise Assessment are reviewed by a neurologist to determine if participants would benefit further from an in-person neurologist evaluation for MG by a provider. Each participant is provided with a report of the neurologist's evaluation. Participants will be followed for 1 year through bimonthly communications to determine if and when they followed up with a clinician and if they received a confirmed diagnosis of myasthenia gravis.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Participants with undiagnosed neuromuscular symptoms
Behavioral: Social media recruitment
Social media users exposed to a variety of paid social media advertisements as a recruitment tool for study enrollment
Behavioral: Follow-up
Patients triaged based on their assessed risk of MG are asked to complete recommended follow-up with a clinician to determine presence of myasthenia gravis
Behavioral: Self-Assessment
Eligible participants are asked to complete self-administered physical tests to assess inducible fatigue of specific muscle groups

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Social media recruitment feasibility
Time Frame: Enrollment period (4-6weeks)
Measure the engagement and feasibility metrics of the social media campaign
Enrollment period (4-6weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
MG Exercise Assessment Tool validity
Time Frame: 1 year from time of enrollment
Estimate preliminary measures of validity for the MG Exercise Assessment Tool

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
