ASSESSING EMERALD AND MC10 BIOSTAMP nPOINT BIOSENSORS FOR RETT SYNDROME

November 12, 2024 updated by: Rett Syndrome Research Trust

Assessing Emerald and MC10 nPoint Biosensors for Rett Syndrome

This is a pilot study of the Emerald device in Rett syndrome patients diagnosed with a confirmed MECP2 mutation. MC10 BioStamp nPoint patches will also be assessed with the goal to develop Rett-specific breathing algorithms

Study Overview

Status

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

The study consists of two sequential cohorts with a total of approximately 20 patients enrolled. Patients in each cohort may participate for up to 4 weeks. Each participant will have up to 2 Emerald devices installed in their home for monitoring sleep, breathing and movement, and will use between 3 and 9 nPoint patches for determining proper patch placement for detecting breathing signals.

The study will consist of a Screening visit, an Observation period, and a Follow-up phone call. The Screening Period will be one day in clinic, the Observation period will be up to 4 weeks at home and the Follow up phone call will be performed at the completion of the Observation Period.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Probability Sample

Study Population

Female patients with Diagnosis of typical Rett Syndrome according to the revised Clinical Diagnostic Criteria and presence of a disease-causing MECP2 genetic mutation.

Description

Inclusion Criteria:

  1. Prior to the conduct of any study-specific procedures, the parent/caregiver/LAR must provide written informed consent. If the caregiver attending the clinic visits is not the parent or LAR, written consent must be obtained from the parent or LAR for the caregiver's participation in the study.
  2. Diagnosis of typical Rett Syndrome according to the revised Clinical Diagnostic Criteria1 and presence of a disease causing MECP2 genetic mutation.
  3. The patient's parent/caregiver/LAR must be able to understand the nature of the study and to allow for the completion of study assessments. The same parent/caregiver/LAR must be capable of providing reliable information about the patient's condition.
  4. Live within approximately 50 to 60 miles of MIT.
  5. Primary language English.
  6. Approximately 4 people or less living in the home. This does not include visiting caregivers.
  7. Must have home access to Wi-Fi.

Exclusion Criteria:

  1. Inability of patient to sleep alone in their own room.
  2. Pets in the home, or caregivers unwilling to keep pets out of the bedroom monitored by Emerald during the Observation Period.
  3. Plans to take a prolonged vacation or to otherwise be out of the home during the Observation Period.
  4. Participation in another device study that could interfere with this study.
  5. Active implantable devices such as pacemakers or defibrillators.
  6. Known allergies or hypersensitivities to adhesives.
  7. Patients with any condition that, in the opinion of the principal investigator, might interfere with the conduct of the study, confound interpretation of the study results, endanger their own well-being, or who may otherwise not be suitable for 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.
Cohort 1
will enroll approximately 5 patients with pronounced respiratory dysfunction. Patients may be enrolled with tremors and or seizures. All patients will be observed via Emerald to capture sleep staging, movement and breathing for up to approximately 4 weeks. Caregivers will keep a daily questionnaire diary of the patient's anxiety, sleep and seizures. MC10 nPoint data will be captured for at least two 24-hour periods in each of the 4 weeks to assess patch placements for breathing detection. Ongoing assessment of MC10 nPoint data may lead to the use of more or less sensors, changes in duration of sensor data collection, or placement as Cohort 1 progresses.Preliminary results from Cohort 1 will determine if Emerald will continue to be evaluated and will inform on MC10 nPoint optimizations for Cohort 2. If preliminary results indicate Emerald is not an effective device, then Emerald will be discontinued
Device: Emerald
The Emerald is a wireless sensor that can track the motion, breathing, and sleep of subjects without touching or requiring any interaction with the subjects, allowing them to go about their normal lives. The physical device is roughly a 30 x 35 x 5 cm box that contains directional antennas and a motherboard to process these signals. In typical operation, the device is mounted onto a wall within a clinic or home setting using peel-away (reversible) mount strips.
Other Names:
  • MC 10
Cohort 2
will enroll approximately 15 patients. Patients with pronounced respiratory dysfunction, tremors, seizures, and/or other expanded features of Rett syndrome deemed appropriate may be enrolled. If Emerald is continued, all patients are observed via Emerald to capture sleep staging, movement and breathing up to for approximately 4 weeks. Caregivers will keep a daily questionnaire diary of the patient's anxiety, sleep and seizures. Ongoing assessment of MC10 nPoint data may lead to the use of more or less sensors, changes in duration of sensor data collection, or placement as Cohort 2 progresses.

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.

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.
