Trial Outcomes & Findings for Attain Stability™ Quad Clinical Study (NCT NCT03099655)

NCT ID: NCT03099655

Last Updated: 2020-01-09

Results Overview

Subjects free of Model 4798 lead-related complications at 6 months post-implant -Model 4798 lead will be considered safe if the probability of subjects free from Attain Stability Quad lead-related complications at 6-months post implant is greater than 87% (i.e. the one-sided 97.5% lower confidence bound must be greater than 87%). Complications were defined in the protocol as, "An adverse event that includes the following is considered a complication: Results in death, Involves any termination of significant device function, or Requires an invasive intervention". Relationship of complication to the Attain Stability Quad lead was determined by an independent Clinical Events Committee.

PRIMARY outcome

Population: Subjects with an attempted Attain Stability Quad Lead Model implant, results come from PMA-S Clinical Report Version 3, 28MAR2019.

PRIMARY outcome

Timeframe: 6 months post-implant

Population: Subjects with an attempted Attain Stability Quad Lead Model implant, results come from PMA-S Clinical Report Version 3, 28MAR2019.

The Model 4798 LV lead has sixteen (16) programmable pacing vectors. The endpoint for the primary efficacy objective is whether or not there is at least one Model 4798 LV lead pacing vector with pacing capture voltage thresholds less than or equal to 2.5V. -Model 4798 lead will be considered effective if the proportion of subjects with at least one Model 4798 LV lead pacing vector with pacing capture voltage thresholds less than or equal to 2.5V at 0.5 ms pulse width (with absence of Phrenic Nerve Stimulation at 5.0 V) at 6 months post-implant is greater than 80%.

PRIMARY outcome

Timeframe: 6 months post-implant

Population: All subjects who are successfully implanted with a Model 4798 lead and with valid pacing data collected 6 months post-implant follow-up visit.

The co-primary efficacy endpoint is whether or not a second Model 4798 lead configuration has a pacing capture threshold less than or equal to 4V, excluding the pacing vector that is already counted to the primary efficacy. -Model 4798 lead will be considered effective if the proportion of subjects with at least one additional Model 4798 LV lead pacing vector with pacing capture voltage thresholds less than or equal to 4.0 V at 0.5 ms pulse width (with absence of Phrenic Nerve Stimulation at 5.0 V) at 6 months post-implant is greater than 80%.
