Trial Outcomes & Findings for RECHARGE Sub-Study to the Implantable Systems Performance Registry (ISPR) (NCT NCT00998660)

NCT ID: NCT00998660

Last Updated: 2015-03-06

Results Overview

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 outcome

Timeframe: 3 months

Population: The 93 implanted subjects accumulated 283.6 subject-months of follow-up through the 3-month visit. There were no reported user-related battery depletion adverse events that required an intervention by a health care professional and/or HCP designee.

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.
