Post-Approval Studies (PAS)

The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Date Current Protocol Accepted 08/21/2018
Study Name MANAGE-HF
General Study Protocol Parameters
Study Design Prospective Cohort Study
Data Source New Data Collection
Comparison Group Device Subjects Serve as Own Control
Analysis Type Analytical
Study Population Transit. Adolescent B (as adults) : 18-21 yrs, Adult: >21
Detailed Study Protocol Parameters
Study Design Description 1. To evaluate and optimize HeartLogic Heart Failure Diagnostics clinical integration and the alert management process (Phase I).

2. To evaluate Heart Logic in regards to patient outcomes of death and heart failure hospitalizations (Phase II).

Study Population Description Test Device: Phases I and II: ICD and CRT-D devices with HeartLogic turned ON

Control Device: Phase II: ICD and CRT-D devices with HeartLogic alerts turned OFF

Sample Size Between 1700 and 2700 subjects will be enrolled in the study:

Phase I: Up to 200 subjects

Up to 200 subjects are required in Phase I to build critical knowledge regarding the clinical integration of HeartLogic and the alert management process.

Phase II: 1500-2500 subjects

The sample size required for Phase II of MANAGE-HF is event-driven.

Between 1500 and 2500 subjects will be enrolled in the trial to accrue the necessary number of endpoint events to sufficiently power the primary endpoint. A total of 864 endpoints events from randomized subjects in Phase II are required to sufficiently power the primary endpoint, based on the following assumptions:

¿ Expected control group incidence of annual heart failure

hospitalization and death = 20%

¿ One-sided Alpha = 5%

¿ Power = 90%

¿ Hazard Ratio = 0.8

¿ Estimated enrollment period = 24 months

¿ Expected Follow-up period = minimum of 24 months for last patient enrolled

Final sample size will be determined during the study using a sample size re-estimation interim analysis.
