Clinical Trial Summary

Prospective, randomised, multicentre, open-label study to assess the non-inferiority of a personalised precision strategy for Sudden Cardiac Death (SCD) prevention in patients with non-ischemic dilated cardiomyopathy with Left Ventricular Ejection Fraction (LVEF) ≤35%

Description:

Prospective, randomised, multicentre, open-label study to assess the non-inferiority of a personalised precision strategy for SCD prevention in patients with non-ischemic dilated cardiomyopathy with LVEF≤35%

Randomization will be 1:1 and patients are allocated to either control strategy or intervention strategy.

In the control strategy group, patients will get an Implantable Cardioverter Defibrillator (ICD) implanted. Patients allocated to the intervention strategy will receive an ICD according to genetic and CMR results. ICD implantation criteria in patients allocated to the personalised strategy group will be the presence of either a Dilated Cardiomyopathy DCM-causing pathogenic or likely pathogenic genetic variants or Late Gadolinium Enhancement (LGE) in Cardiac Magnetic Resonance (CMR). Patients without DCM-associated genetic variants and without LGE on CMR will not receive standard treatment but an ICD will not be implanted on them.

Intervention

Other:
• Control Strategy
ICDs will be implanted in all patients according to current recommendations
• Personalized precision ICD implantation Strategy based in genetic findings and CMR results
Patients allocated to the intervention strategy will receive an ICD according to genetic and CMR results. ICD implantation criteria in patients allocated to the personalised strategy group will be the presence of either a DCM-causing pathogenic or likely pathogenic genetic variants or LGE in CMR. Patients without DCM-associated genetic variants and without LGE on CMR will not receive standard treatment but an ICD will not be implanted on them.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Composite end-point of all cause death, hospitalization due to device-related complications, and non-fatal major arrhythmic events.		4 years
Secondary	All-cause death		4 years
Secondary	SCD		4 years
Secondary	Hospitalisation for device-related complications		4 years
Secondary	Non-fatal major arrhythmic events		4 years
Secondary	cost-effectiveness	Incremental Cost-effectiveness ratio (ICER) of personalized ICD allocation strategy in non-ischemic DCM [ Time Frame: The time horizon of the evaluation will be limited to 4 years ]; The ICER of the personalized ICD allocation strategy compared with standard strategy is defined as the ratio between the variation in costs and the variation in effectiveness between both strategy groups. In the personalized strategy group, costs will include those related to personalization tests (CMR and genetic analysis) plus costs related to implanting and carrying an ICD (in the number of patients who eventually receive a device). In the control group, costs will include only the latter concept. Costs will be measured in Euros. The variation in effectiveness will be measured both in terms of life years gained, measured in years, and in terms of quality of life gained, measured in QALY. In the first case, ICER will be measured as Euros/year; in the second, it will be measured as Euros/QALY.	4 years
Secondary	Quality of life assessed by KCCQ, EQ-5D and HADS		4 years
