A Low Interventional Study to Monitor Activity Using Wearable Sensors in Duchenne Muscular Dystrophy

October 14, 2021 updated by: Pfizer

A SINGLE-SITE, PROSPECTIVE, NATURAL HISTORY LOW INTERVENTIONAL STUDY TO ESTABLISH NORMATIVE DATA OF REAL-WORLD ACTIVITY MEASURES USING WEARABLE SENSORS IN AMBULATORY BOYS WITH DUCHENNE MUSCULAR DYSTROPHY (DMD)

The purpose of this low interventional study is to collect data on everyday movement in boys with Duchenne muscular dystrophy (DMD) using wearable activity sensors. The activity sensors could provide useful information beyond what is currently collected by functional (movement, strength) assessments in clinic. This information can help with the understanding of the impact of DMD, and perhaps with how possible treatments can affect this impact.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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.

Ages Eligible for Study

4 years to 12 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Non-Probability Sample

Study Population

Ambulatory boys with Duchenne muscular dystrophy who receive care at Nationwide Children's Hospital

Description

Inclusion Criteria:

  • Diagnosis of Duchenne muscular dystrophy confirmed by medical history and genetic testing
  • Body weight between 15 and 50 kg
  • Receipt of glucocorticoids for 6 months and a stable daily dose for at least 3 months prior to study entry
  • Ability to rise from floor within seven (7) seconds and ability to walk

Exclusion Criteria:

  • Current exposure to systemic immunosuppressant agents other than glucocorticoids.
  • Prior exposure to any gene therapy agent, including exon-skipping and missense agents.
  • Exposure to other investigational drugs within 30 days or 5 half-lives, whichever is longer.
  • Any injury which may impact functional testing per investigator's judgement. Previous injuries must be fully healed prior to consenting. Prior lower limb fractures must be fully healed and at least 3 months from injury date at screening.
  • Any planned surgeries which may impact physical activity and performance.
  • Presence or history of musculoskeletal or neurological disease in addition to DMD.
  • Any known allergies or skin reactions to stainless steel, versaflex, and silicon that may cause possible discomfort by wearable sensors.
  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, cancer, autoimmune or allergic disease that may interfere with the study conduct as per investigator's judgment, excluding untreated, asymptomatic, seasonal allergies at time of screening.
  • Investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or participants who are Pfizer employees, including their family members, directly involved in the conduct of the study.

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.

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
Time Frame
Mean change from baseline and variability of activity measures
Time Frame: baseline, 3, 6, 9, and 12 months
baseline, 3, 6, 9, and 12 months

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
Time Frame
Mean change from baseline in functional assessment scores obtained in the clinic
Time Frame: baseline, 3, 6, 9, and 12 months
baseline, 3, 6, 9, and 12 months
Comparison of mean changes from baseline and correlation coefficient between activity monitoring data and functional data obtained in clinic
Time Frame: baseline, 3, 6, 9, and 12 months
baseline, 3, 6, 9, and 12 months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
