This study is a randomized prospective, single-center feasibility study of the use and benefits of NeuRx DPS in patients undergoing tracheostomy for failure to wean.

Study Overview

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

15 patients undergoing tracheostomy for failure to wean will be randomized into one of 3 cohorts (5 in each cohort): Cohort A: tracheostomy with no intervention; Cohort B: tracheostomy with DPS implantation and immediate stimulation and monitoring and Cohort C: tracheostomy with DPS implantation with monitoring followed with stimulation on day 5.

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.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patient is intubated, on mechanical ventilation, undergoing tracheostomy, and expected to undergo mechanical ventilation for at least 5 days
  • Signed written informed consent has been obtained prior to performing any study related procedure(s)
  • Subject is at least 18 years of age
  • Negative pregnancy test if the patient is a female of child-bearing potential. (Females of child-bearing potential exclude women who are post-hysterectomy or post-menopausal.)

Exclusion Criteria:

  • Diaphragm malformation which makes electrode insertion impossible
  • Presence of an implantable cardioverter-defibrillator
  • Severe chronic obstructive pulmonary disease (COPD)
  • Subject is pregnant or breastfeeding
  • Diagnosis of neuromuscular disease or high level spinal cord injury prior to tracheostomy
  • Terminal patients expected to die during their stay in the hospital
  • Participation in other clinical studies that could interfere with the results in the ongoing study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Tracheostomy, no DPS
5 patients undergoing tracheostomy for failure to wean will receive no additional intervention.
Experimental: Trachesotomy with immediate DPS stimulation and monitoring
5 patients undergoing tracheostomy for failure to wean will have DPS implanted concurrently and receive immediate stimulation and monitoring.
Device: NeuRx Diaphragm Pacing System (DPS)
4 electrodes are implanted into the diaphragm, 2 on each side, during the tracheostomy procedure. The electrodes are connected to the NeuRx external stimulator which will be used to stimulate and monitor diaphragm activity.
Active Comparator: Trachesotomy with DPS monitoring, stimulation on day 5
5 patients undergoing tracheostomy for failure to wean will have DPS implanted concurrently and receive immediate monitoring followed by stimulation on day 5 post-procedure.
Device: NeuRx Diaphragm Pacing System (DPS)
4 electrodes are implanted into the diaphragm, 2 on each side, during the tracheostomy procedure. The electrodes are connected to the NeuRx external stimulator which will be used to stimulate and monitor diaphragm activity.

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
Device and procedure safety
Time Frame: Through study completion, an average of 6 years
Device or procedure-related adverse events from time of implant until removal of electrodes prior to discharge from the hospital or 30 days, whichever occurs first
Through study completion, an average of 6 years
Monitoring
Time Frame: Through study completion, an average of 6 years
Detection of rhythmic diaphragm burst activity for identifying the level of diaphragm dysfunction
Through study completion, an average of 6 years
Stimulation
Time Frame: Through study completion, an average of 6 years
Increase in magnitude of diaphragm burst activity with stimulation
Through study completion, an average of 6 years

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
Effects of diaphragm stimulation
Time Frame: Through study completion, an average of 6 years
Effects of diaphragm stimulation on ventilator parameters (plateau pressure, compliance, tidal volumes), oxygenation, weaning time, extubation failure, and length of stay
Through study completion, an average of 6 years

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.
Outcome Measure
Measure Description
Time Frame
Electrode removal
Time Frame: Through study completion, an average of 6 years
(3) Safe and complete removal of electrodes prior to discharge from the hospital or thirty (30) days, whichever occurs first
Through study completion, an average of 6 years
