RECHARGE Sub-Study to the Implantable Systems Performance Registry (ISPR) (RECHARGE)

February 19, 2015 updated by: MedtronicNeuro
The purpose of this study is to assess the recharge feature of the Activa RC System in patients who are receiving Deep Brain Stimulation (DBS) for Parkinson's Disease (PD), Essential Tremor (ET), or dystonia.

Study Overview

Status

Status

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

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.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

7 years and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patient is enrolled in the Implantable Systems Performance Registry (ISPR) and will receive one Activa RC as their first implantable neurostimulator or as a replacement implantable neurostimulator for DBS.
  • Patient must meet the indications in the Activa RC labeling.
  • Patient (or patient's legally authorized representative) signs and dates the appropriate RECHARGE Informed Consent Form and/or Informed Assent Form and Authorization to Use and Disclose Health Information (HIPAA, US only).
  • Patient has a diagnosis of Parkinson's Disease, Essential Tremor, or dystonia that meets the approved indication for Activa RC in the applicable geography.
  • Patient with dystonia is 7 years of age or older (EU only).
  • Patient with either PD or ET is 18 years of age or older.
  • Patient (or caregiver) is able to use the patient programmer and correctly interpret the icons.
  • Patient (or caregiver) is able and willing to regularly monitor the status of the rechargeable battery and respond appropriately.
  • Patient (or caregiver) is able to locate the INS, position the recharge antenna for sufficient coupling, put on the recharge holster/belt, and monitor progress during the recharge session.
  • Patient (or caregiver) is able to perform recharging activities for sufficient duration and frequency to maintain therapy and to perform recharging activities on an ongoing basis.
  • Patient is willing and able to comply with protocol requirements.

Exclusion Criteria:

  • Patient has a contraindication identified in the Activa RC labeling.
  • Patient who is currently enrolled in or plans to enroll in any concurrent drug and/or device study that may confound the results of the RECHARGE study.
  • Patient has or will be implanted with a non-Medtronic Deep Brain Stimulation system component.

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
Identify the Rate of User-related Battery Depletion Adverse Events Per Subject-month Requiring Intervention by a Health Care Professional (HCP) and/or the HCP's Designee, Within the First 3 Months of the Activa RC System Being Turned ON.
Time Frame: 3 months
Subject-months of follow-up were defined as the time from device activation to the earlier of a subject's 3-month visit or until the subject exited from the study. Any user-related battery depletion adverse events requiring intervention by a health care professional (HCP) and/or the HCP's designee were collected. The event rate per 100 subject-months of follow-up is defined as the number of user-related battery depletion events divided by the total subject follow-up months through the 3-month visit, all multiplied by 100.

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.
