Randomized Controlled Trial of Lipid Apheresis in Patients With Elevated Lipoprotein(a) (ELAILa)

Charité University Medicine Berlin

Status: Withdrawn

Conditions: Hyperlipoproteinemia(a); Progressive Cardiovascular Disease

Treatments: Procedure: Lipid apheresis; Other: Standard care

Study type: Interventional

Funder types: Other

Identifiers

ELAILa-01

Details and patient eligibility

About

Lipoprotein(a) [Lp(a)] is an independent risk factor for cardiovascular disease. Non-medical treatment measures (e.g. dietary therapy or weight loss) can hardly influence Lp(a) plasma concentrations. Drug therapy has only limited influence, e.g. treatment with niacin. Statins are usually without effect. Lipid apheresis is the only treatment known to lower elevated Lp(a) levels in a relevant way. In patients with pronounced elevation of Lp(a) and normal LDL cholesterol levels, who suffer from progressive cardiovascular disease, the treatment with lipid apheresis seems to be a last-resort treatment option. The current trial will evaluate the effectiveness of lipid apheresis on cardioavascular endpoints.

Lipoprotein(a) [Lp(a)] is an independent risk factor for cardiovascular disease. Non-medical treatment measures (e.g. dietary therapy or weight loss) can hardly influence Lp(a) plasma concentrations. Drug therapy has only limited influence, e.g. treatment with niacin. Statins are usually without effect. Lipid apheresis is the only treatment known to lower elevated Lp(a) levels in a relevant way. In patients with pronounced elevation of Lp(a) and normal LDL cholesterol levels, who suffer from progressive cardiovascular disease, the treatment with lipid apheresis seems to be a last-resort treatment option. The current trial will evaluate the effectiveness of lipid apheresis on cardioavascular endpoints. The trial is a randomized multicenter trial in Germany. Patients will be randomized to the apheresis group or to the control group. All patients will receive maximal risk minimizing therapies. The apheresis group will receive in addition weekly lipid apheresis. The principal outcome parameter is a composite endpoint of non-fatal myocardial infarction, interventional therapeutic procedure (PCI, stenting), coronary bypass surgery (CABG), non-fatal ischemic cerebrovascular accident, hospitalization due to acute coronary syndrome (ACS), critical limb ischemia, peripheral arterial revascularization procedure; amputation, death from cardiovascular cause.
