Cholesterol Lowering With EVOLocumab to Prevent Cardiac Allograft Vasculopathy in De-novo Heart Transplant Recipients (EVOLVD)

EVOLVD: Cholesterol Lowering With EVOLocumab to Prevent Cardiac Allograft Vasculopathy in De-novo Heart Transplant Recipients

The main goal of this study is to evaluate the effect of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor evolocumab on cardiac allograft vasculopathy in de novo heart transplant recipients.

Secondary objectives are to assess the impact of treatment on: i) cholesterol levels, ii) renal function, iii) inflammation, iv) quality of life, v) cardiac function as assessed by biomarkers and echocardiography, vi) the number of rejections, and (vii) safety and tolerability. As an exploratory outcome, the investigators will asses the effect of treatment on clinical events (death, myocardial infarction, cerebral stroke, cancer, end stage renal disease).

Study Overview

• Status: Completed
• Conditions: Cardiac Allograft Vasculopathy
• Intervention / Treatment: Drug: Evolocumab; Drug: Placebo

Detailed Description

Cardiac allograft vasculopathy is an important cause of morbidity and mortality in heart transplant recipients. Previous data show that, although clinical coronary artery disease often manifests years after heart transplantation, there are substantial changes in the coronary artery intima thickness over the first year after transplantation, suggesting that the adverse process starts shortly after transplantation. Moreover, the investigator's previous data have suggested that, whereas early intervention can prevent the long-term progression of cardiac allograft vasculopathy, the same intervention is less effective when administered late after heart transplantation. Thus, there seems to be a window of opportunity for preventive measures against cardiac allograft vasculopathy in de-novo transplant recipients.

The strong association between cholesterol levels and coronary heart disease in the general population, the high cholesterol levels in heart transplant recipients, the high prevalence of vasculopathy in the cardiac allograft, and the association between cholesterol levels and cardiac allograft vasculopathy together provide a strong rationale for aggressive cholesterol lowering in heart transplant recipients. Statins improve outcomes in heart transplant recipients, but their limited effect on post-transplant cholesterol levels, adverse effects, and drug interactions contribute to their not providing sufficient prophylaxis against post-transplant atherosclerotic disease.

Evolocumab is a well-tested drug with a favourable safety profile. It effectively reduces cholesterol levels on top of statin therapy in patients with coronary heart disease. The investigators hypothesise that evolocumab on top of statin therapy will significantly lower low density lipoprotein (LDL) levels in de novo heart transplant recipients. The investigators assume that this reduction in cholesterol levels will manifest as a reduced burden of cardiac allograft vasculopathy as measured by intracoronary ultrasound. Ultimately, the investigators believe that a reduced burden of vasculopathy will translate to reduced morbidity and long-term mortality in heart transplant recipients. The EVOLVD trial is a randomised, placebo-controlled, double-blind study designed to test the hypothesis that treatment with evolocumab can ameliorate cardiac allograft vasculopathy in heart transplant recipients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Evolocumab; Evolocumab (Repatha®) will be administered subcutaneously once monthly in the abdomen, thigh, or upper arm for the duration of the treatment period (one year). The 420 mg evolocumab/placebo will be administered by giving 3 injections consecutively within 30 minutes using the single-use prefilled autoinjector.	Drug: Evolocumab; 420 mg evolocumab will be administered subcutaneously by giving 3 injections consecutively within 30 minutes using the single-use prefilled autoinjector.; Other Names: Repatha
Placebo Comparator: Placebo; The placebo is presented in an identical prefilled autoinjector. It is supplied as a sterile, single-use, preservative-free solution for subcutaneous injection in a disposable, spring-based prefilled autoinjector. The prefilled autoinjector contains a 1.0 mL deliverable volume of 1.1% (w/v) sodium carboxymethylcellulose, 250 mM proline, 10 mM acetate, and 0.01% (w/v) polysorbate 80, pH 5.0.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximal intimal thickness	The maximal intimal thickness will be measured by coronary intravascular ultrasound at 12 months after randomization. The maximal intima thickness is defined as the largest distance (in mm) from the intimal leading edge to the external elastic membrane.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cardiac allograft vasculopathy	Incidence of cardiac allograft vasculopathy, defined as mean a maximal intimal thickness ≥0.5 mm over the entire matched segment, will be measured by intravascular ultrasound 12 months after randomization.	12 months
Total atheroma volume	The total atheroma volume will be measured by intravascular ultrasound.	12 months
The index of microvascular resistance	The index of microcirculatory resistance will be obtained at the time of routine coronary angiography after heart transplantation at baseline (4-10 weeks) and at the end of treatment 12 months after randomization.	12 months
Low-density lipoprotein (LDL) cholesterol	Blood lipids must be assessed after end-of treatment only, to avoid what will effectively amount to study drug allocation unblinding. To avoid bias, the investigators will be blinded to the lipid analyses.	12 months
Estimated glomerular filtration rate (eGFR)	The glomerular filtration rate (in in ml/min/1.73 m2) will be estimated by the MDRD formula: 175 x (SCr)-1.154 x (age)-0.203 x 0.742 [if female] x 1.212 [if black], where SCr is serum creatinine in mg/dl, and age is measured in years.	12 months

The 3-level version of EQ-5D (EQ-5D-3L) questionnaire	The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems.	12 months
The Beck Depression Inventory (BDI)	The BDI is a 21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression.	12 months
N-terminal pro-B-type natriuretic peptide (NT-proBNP)	NT-proBNP values will be used for endpoint analyses.	12 months
Cardiac troponin T (TnT)	Troponin T-values will be used for endpoint analyses.	12 months
Number of rejections	Number of all rejections will be recorded through the duration of the study.	12 months
Number of adverse events (AE)	The standard time period for collecting and recording AE and SAEs will begin at the start of study treatment and will continue for 30 day after end-of treatment (at which time approximately 30 days will have passed since the last study drug injection.	12 months
Number of major clinical adverse events	The number of major clinical adverse events, defined as death, myocardial infarction, percutaneous coronary intervention/coronary bypass surgery, cerebral stroke, cancer, end stage renal disease (exploratory endpoint).	12 months
