About this study

Official title: Lipid Management in Renal Transplant Recipients: a Pilot Study Evaluating the Use of a Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK-9) Inhibitor Evolocumab.

Cardiovascular disease is the leading cause of mortality after renal transplantation, accounting for more than 30% of deaths. Elevated lipid levels (hyperlipidemia) are a frequent finding following transplantation and the immunosuppressive medications play a central role in the development or worsening of hyperlipidemia. In the general population, the correlation between elevated serum cholesterol and increased risk of cardiovascular disease is well established and the reduction in serum LDL cholesterol has proved to significantly reduce both morbidity and mortality.

Statin based drugs are the standard of care in the management of hyperlipidemia. Commonly used statin-based drugs include atorvastatin (Lipitor), fluvastatin (Lescol, Lescol XL), lovastatin (Mevacor, Altoprev), pravastatin (Pravachol), rosuvastatin (Crestor), simvastatin (Zocor), and pitavastatin (Livalo). These drugs have been proven to lower lipid levels as well as cardiovascular risk. However, statin-based drugs also cause a variety of side effects. While the most commonly encountered side effects are toxicity to the liver and muscles, a few others have also been known to cause increased excretion of protein in the urine and kidney failure. These side effects are also more common in a renal transplant recipient due to the simultaneous administration of drugs that prevent rejection. Therefore, there is an emergent need for newer drugs which are both efficient and safe especially in this population PCSK-9 inhibitors (Proprotein Convertase Subtilisin Kinase-9 inhibitors) are a new class of drugs that are highly efficient in lowering lipid levels in the general population. However, an exclusive trial involving kidney transplant recipients is yet to be done. Through this study, we would like to evaluate the safety and tolerability of Evolocumab (trade name: Repatha) which is a PCSK-9 inhibitor developed by Amgen, Inc in renal transplant recipients. The study would involve a total of 120 patients across 3 different hospitals in Boston, Massachusetts.

Read the detailed description

Cardiovascular disease is the leading cause of death in renal transplant recipients (RTR). 44% of RTR have LDL-C greater than 100mg/dL, six months after transplant. The correlation between the increase in serum LDL level and the increased risk of atherosclerotic cardiovascular disease (ASCVD) is well established. A reduction in LDL level is associated with a decreased risk of mortality and morbidity in patients with ASCVD. Statins have been the long-standing drug of choice in treating dyslipidemia. A single prospective randomized trial known as the ALERT trial compared the benefits of statins to placebo in transplant recipients. The original study consisted of 2000 RTR and an extension of this study evaluated 1652 patients and demonstrated a 21% reduction in major cardiac events (p=0.036) and a 29% reduction in cardiac death or definite non-fatal myocardial infarction (p=0.014). Even though statins decrease the probability of cardiovascular events there was no difference in graft survival or mortality benefit in RTR. Another concerning factor for the use of statins is the tolerability of these drugs. Statins have been associated with hepatotoxicity and myotoxicity, the incidence of which is higher in RTR. This effect is dose-related and may be precipitated by the administration of agents that inhibit cytochrome p450 isoenzymes such as Tacrolimus and Cyclosporine which are the most commonly used immunosuppressants. Another statin based drug (Fluvastatin) has been associated with proteinuria and renal failure. Hence there is a need to explore novel treatment options in the management of dyslipidemia, particularly in RTR. PCSK-9 inhibitors (Proprotein Convertase Subtilisin Kinase-9 inhibitors) have shown to decrease LDL levels by 60% in patients on statin therapy. However, these drugs have been studied sparingly in patients with Chronic Kidney Disease (CKD) and have not yet been analyzed in RTR.

The study will involve 120 patients across 3 different hospitals. Two different but equivalent drug dosing strategies are available. A 420mg monthly subcutaneous injection using an on-body infusor (Repatha Pushtronex system) or a 140mg subcutaneous injection once every two weeks using a prefilled auto-injector (Repatha SureClick). The choice of dosing strategy will be based on patient preference. This study will be conducted over one year.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change in LDL Cholesterol From Baseline to 12 Months

    The primary efficacy measure is the percent change in LDL cholesterol from baseline to 12 months. The 12-month LDL value is defined as the measurement closest to 12 months within a prespecified window of Months 11 to 13 following treatment initiation. LDL cholesterol is measured in mg/dL.

    Measured: Baseline to 12 months (Month 0 to Month 12; assessment window Months 11-13)

Secondary outcomes (1)
  1. Absolute Change in LDL Cholesterol From Baseline to 12 Months

    Absolute change in LDL cholesterol from baseline to 12 months. The 12-month LDL value is defined as the measurement closest to 12 months within a prespecified window of Months 11 to 13 following treatment initiation. LDL cholesterol is measured in mg/dL.

    Measured: Baseline to 12 months (Month 0 to Month 12; assessment window Months 11-13)

Yes. Results are posted in the registry (first posted 16 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change in LDL Cholesterol From Baseline to 12 Months (time frame: Baseline to 12 months (Month 0 to Month 12; assessment window Months 11-13)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04608474, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2026; AzTrials last refreshed its copy on 6 Nov 2026.
