January 16, 2015 updated by: CardioMEMS

A Multi-Center, Non-Randomized, Prospective Trial to Evaluate the Safety and Feasibility of Wireless, Intermittent Monitoring of Right Heart Pressures in Adult Heart Failure Subjects

The purpose of the trial is to evaluate the wireless monitoring of pulmonary artery pressure using the CardioMEMS HF Pressure Measurement System in adult subjects with NYHA Class III Heart Failure.

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.

Detailed Description

The trial is designed to demonstrate that the CardioMEMS Sensor can be positioned in the right or left pulmonary artery, and that Sensor pressure measurements correlate to standardized methods of intra-cardiac pressure measurements post-sensor implant and at the 60 day visit. Safety will be monitored by the occurrence of adverse events throughout the trial.

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.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
The primary objective is to evaluate the wireless monitoring of pulmonary artery pressure using the CardioMEMS HF Pressure Measurement System in adult subjects with Class III Heart Failure.
Time Frame: after implant of the sensor and at 60 day visit
The trial will demonstrate that the CardioMEMS Sensor can be positioned in the right or left pulmonary artery, and the Sensor pulmonary artery pressure measurements correlate to standardized methods of intra-cardiac pressure measurements immediately after deployment of the sensor and at the 60 day follow-up visit. Safety is assessed by monitoring the occurrence of adverse events.
after implant of the sensor and at 60 day visit

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
To demonstrate the capability of the CardioMEMS HF System to obtain the pressure measurement from the Sensor and transmit the pulmonary artery pressure data to a secure database.
Time Frame: after deployment of the sensor and at 60 days
after deployment of the sensor and at 60 days

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.
