Re-evaluation of Optimal Re-synchronisation Therapy in Patients With Chronic Heart Failure (RESET-CRT)

Re-evaluation of Optimal Re-synchronisation Therapy in Patients With Chronic Heart Failure - An Investigator-initiated, Event-driven, Prospective, Parallel-group, Randomised, Open, Blinded Outcome Assessment (PROBE), Multi-centre Trial Without Investigational Medical Products (Proof of Strategy Trial)

The objective of the study is to demonstrate that in patients with chronic heart failure who receive optimal medical treatment for this condition and have indication for Cardiac Resynchronisation Therapy, the implantation of a pacemaker (index group) is not inferior to defibrillator (control group) with respect to all-cause mortality.

Study Overview

• Status: Terminated
• Conditions: Chronic Heart Failure
• Intervention / Treatment: Procedure: CRT-P implantation; Procedure: CRT-D implantation

Detailed Description

Heart failure is a leading cause of death, hospitalisation, impaired quality of life and health expenditure. Symptoms and survival can be significantly improved by implantation of a device for Cardiac Resynchronisation Therapy (CRT). CRT devices are available as biventricular pacemakers (CRT-P) or as significantly more complex and cost-intensive biventricular defibrillators (CRT-D).

In patients who have previously experienced a life-threatening arrhythmia, the choice of the CRT-D (and not the CRT-P) is imperative but these are a small minority of patients. For the vast majority of patients receiving CRT therapy, there is currently considerable uncertainty as to whether the defibrillator function is needed and whether its benefits outweigh its risks. The defibrillator function may protect patients from sudden cardiac death. On the other hand, device-associated complications such as device infections appear to be increased; furthermore the defibrillator comes along with specific adverse events, particularly inappropriate shocks. These shocks are common and not only traumatic to patients (potentially leading to post-traumatic stress syndrome, anxiety disorders and depression), they also are negatively associated with overall survival.

The objective of the trial is to demonstrate that in patients with chronic heart failure who receive optimal medical treatment for this condition and have indication for CRT, the implantation of a CRT-P (index group) is not inferior to CRT-D (control group) with respect to all-cause mortality. Patients with an indication for CRT will be randomised to CRT-P or CRT-D.

RESET-CRT is an event-driven trial with a planned number of randomised and treated patients of at least n=1,356 (maximum of 2,004) and of 361 primary endpoints within an estimated median follow-up period of about 29 to 40 months.

No investigational medical product is defined to be used within RESET-CRT since only the therapeutic strategy (CRT-D versus CRT-P) is a pre-defined study treatment and allocated by random group (Proof of Strategy Trial). The devices to be implanted will be decided by the treating physician on the basis of the situation of the individual study patient and in line with local policies in routine clinical care.

Duration of study period:

Enrolment of 1,356 patients is expected to be completed within 52 months after inclusion of the first patient, i.e., by 31 December 2022. With an overall annual event rate between 9.0% and 12.5%, 361 primary endpoints will have occurred within 9 to 20 months of randomisation of the last patient (between 30 September 2023 and 31 August 2024). Under these circumstances, the total study duration will be between 62 and 73 months.

The Steering Committee of the study might prolong the recruitment period, for instance by 12 months, in the event of an unexpected slower recruitment rate or an overall event rate < 9.0% for the primary endpoint.

For individual patients, the expected median follow-up time is between 29 and 40 months, with a minimum between 9 and 20 months and a maximum between 61 and 72 months. Follow-up may be prolonged by 12 months in the event of a prolonged recruitment period.
