Trial Outcomes & Findings for Ingenio Device Algorithm Study (NCT NCT01441583)

NCT ID: NCT01441583

Last Updated: 2024-03-21

Results Overview

Accuracy was evaluated by the proportion of tests resulting in an RAAT commanded threshold with \|Manual unipolar threshold - commanded threshold\| ≤ 0.5V. Subjects were allowed to contribute multiple paired datasets for this endpoint analysis, one set each from the 1-month and 3-month visits. Paired datasets from the 1-month and 3-month visits were pooled for purposes of endpoint analysis. A paired dataset consisted of the manual unipolar threshold and the commanded threshold obtained at a visit.

Participant Flow

Subjects were recruited from the general patient population indicated for a dual chamber pacemaker or cardiac resynchronization therapy pacemaker implantation at 15 study centers. First enrollment date was in October 2011 and the last subject was enrolled in March 2012.

Of 139 subjects, 132 were implanted with a study device. Of those subjects who were not implanted with a study device 4 signed informed consent, met eligibility criteria and had anesthesia administered in preparation for the surgical procedure but did not receive a study device (classified as 'Attempt') and 3 signed the informed consent, met eligibility criteria but did not undergo an implant (classified as an 'Intent').

PRIMARY outcome

Timeframe: 3 months post implant

Population: Arms/Groups are only applicable for the outcome measure 'Secondary Outcome: RYTHMIQ - Median Relative Reduction of RV Pacing Percent (RVPP) for RYTHMIQ Programmed to ON vs. RYTHMIQ Programmed to OFF'. This outcome measure was analyzed only for the combined population. Analysis performed on subjects with paired datasets, each consisting of a commanded RAAT threshold and manual unipolar threshold collected at the 1- and 3-month visits.

Accuracy was evaluated by the proportion of tests resulting in an RAAT commanded threshold with \|Manual unipolar threshold - commanded threshold\| ≤ 0.5V. Subjects were allowed to contribute multiple paired datasets for this endpoint analysis, one set each from the 1-month and 3-month visits. Paired datasets from the 1-month and 3-month visits were pooled for purposes of endpoint analysis. A paired dataset consisted of the manual unipolar threshold and the commanded threshold obtained at a visit.

Arms/Groups are only applicable for the outcome measure 'Secondary Outcome: RYTHMIQ - Median Relative Reduction of RV Pacing Percent (RVPP) for RYTHMIQ Programmed to ON vs. RYTHMIQ Programmed to OFF'. This outcome measure was analyzed only for the combined population and both pacemakers and CRT-P devices were pooled for the analysis. The analysis assesses the system-related complication (SRC) -free rate (excluding LV related events for CRT-P subjects) for subjects implanted or attempted to be implanted with a study device through the first 90 days following the implant procedure.

Arms/Groups are only applicable for the outcome measure 'Secondary Outcome: RYTHMIQ - Median Relative Reduction of RV Pacing Percent (RVPP) for RYTHMIQ Programmed to ON vs. RYTHMIQ Programmed to OFF'. This outcome measure was analyzed only for the combined population (pacemaker and CRT-P). Accuracy was evaluated by the proportion of tests resulting in an RAAT ambulatory threshold with \|ambulatory threshold - commanded threshold\| ≤ 1.0V. Subjects were allowed to contribute multiple paired datasets for this endpoint analysis, one set each from the 1-month and 3-month visits. Paired datasets from the 1-month and 3-month visits were pooled for purposes of endpoint analysis. A paired dataset consisted consisted of the ambulatory threshold obtained within 7 days prior to the visit and the commanded threshold obtained at the visit.

Arms/Groups are only applicable for the outcome measure 'Secondary Outcome: RYTHMIQ - Median Relative Reduction of RV Pacing Percent (RVPP) for RYTHMIQ Programmed to ON vs. RYTHMIQ Programmed to OFF'. This outcome measure was analyzed only for the combined population (pacemaker and CRT-P). Accuracy was evaluated by the proportion of tests with an appropriate commanded RAAT test outcome. An appropriate RAAT outcome consists of either a device-determined threshold or a code indicating that a threshold could not be determined and representing a condition that is beyond the control of the RAAT feature and could occur as well in manual threshold test, such as atrial fibrillation.

Population: Pacemaker subjects with RYTHMIQ information available for both randomization periods.

Chronic success is assessed by a median relative reduction of RV pacing percent (RVPP) for RYTHMIQ On at Pre-Discharge, Off at 1-Month vs. RYTHMIQ On at Pre-Discharge, Off at 1-Month. All patients received both RYTHMIQ programmed to ON and programmed to OFF in two consecutive periods, where the patient's programming allocation was randomized for the first period. Then a crossover to the alternate setting occurred for the second period once the end of the first period was reached.

Population: Pooled subjects with a sufficient pacing output voltage to capture the right atrium at the 1-month and the 3-month follow-up visits.

This outcome measure was analyzed only for the combined population (Pacemaker and CRT-P). The sufficient pacing output voltage that is able to capture the right atrium was evaluated by the proportion of Right Atrial Automatic Threshold (RAAT) tests with \[RAAToutput ≥ (max(BP,UP) + δ )\] where BP refers to the manual bipolar threshold, UP refers to the manual unipolar threshold, and δ refers to the safety margin of 0.5V. Subjects were allowed to contribute multiple paired datasets for this endpoint analysis, one set each from the 1-month and 3-month visits. Paired datasets from the 1-month and 3-month visits were pooled for purposes of endpoint analysis. A paired dataset consisted of the commanded threshold and the maximum manual threshold (i.e. the maximum of the manual unipolar and manual bipolar thresholds) obtained at a visit.

The study's primary endpoints were designed to assess adverse events for all participants under one category of Cardiac Implantable Electronic Devices (CIED) safety as a unified group. Reporting thus reflects the collective safety profile of CIED interventions as planned and analyzed. This approach was consistent with the study's protocol and objectives, which did not include arm/group-specific AE analysis as a key outcome.

n=136 participants at risk
The study's primary endpoints were designed to assess adverse events for all participants under one category of Cardiac Implantable Electronic Devices (CIED) safety as a unified group. Reporting thus reflects the collective safety profile of CIED interventions as planned and analyzed. This approach was consistent with the study's protocol and objectives, which did not include arm/group-specific AE analysis as a key outcome.
