Pilot Study to Investigate the Creation of Physiological Rhythm by Closed Loop Stimulation in hEart Failure pAtients With chronoTropic incompEtence (BIO|CREATE)

May 23, 2019 updated by: Biotronik SE & Co. KG

BIO|CREATE Pilot Study

The study assesses the effect of Closed Loop Stimulation (CLS) on the ventilatory efficiency slope and estimates the patient responder rate to CLS in patients with severe chronotropic incompetence treated with a cardiac resynchronization therapy (CRT) device.

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

In patients with pharmacological refractory heart failure (HF), systolic dysfunction, and cardiac dyssynchrony, the cardiac resynchronization therapy (CRT) reduces the risk of death, and improves symptoms and quality of life.

A considerable portion (80%) of patients with a CRT indication has a chronotropic incompetence (CI). CI usually induces a stress intolerance which negatively affects the quality of life. In addition of being a marker of diminished exercise capacity, severe CI (sCI) may be an independent predictor of mortality.

The sensor-based rate adaption provided by the implanted CRT device delivers a possible therapeutic approach for the CI.

Usually, rate adaption is achieved by an accelerometer. The previous studies in terms of effectiveness of rate adaption in CRT patients with CI showed inconsistent results.

In addition to an accelerometer to deliver the rate adaption BIOTRONIK provides closed loop stimulation (CLS) as unique feature in a CRT device. CLS determines the appropriate heart rate based on intra-cardiac impedance measurements. These measurements reflect changes of the cardiac contraction dynamics in reaction to information coming from the autonomic nervous system. CLS takes the information on the contraction dynamics and translates it into an adequate heart rate adaptation, thus delivering physiologically appropriate therapy.

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.

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
