Detailed Description

STUDY DESIGN An open-label, prospective phase III study to compare the efficacy and safety of administering evolocumab versus treatment with LDLapheresis in patients with familial hypercholesterolemia and high cardiovascular risk.

STUDY POPULATION The chosen population is constituted by patients belonging to the LDL-apheresis program of the General University Hospital Gregorio Marañón with the diagnosis of familial hypercholesterolemia and a history of cardiovascular disease.

Number of patients expected to participate in the study according to the base of patients treated with LDL-apheresis: 10.

STUDY DESIGN:

Non-controlled intervention study to evaluate the different therapies in the treatment of hypercholesterolemia, in which each patient will be self-controlled. The variables will be analyzed during different phases

  1. LDL-apheresis phase: Retrospectively during the previous year, pre- and postapheresis variables will be collected from the following lipid parameters: total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, atherogenicity index, Lipoprotein A, apo-A, apo- B; inflammatory parameters: PCR, ferritin, fibrinogen, leukocytes and polymorphonuclear and immunological parameters: immunoglobulins and complement.
  2. Evolocumab phase: LDL-apheresis will be suspended for three months and Evolocumab administered: 140 mg / 15 days subcutaneously. The same parameters indicated in the previous section will be measured every two weeks.
  3. Combined phase: During the following three months evolocumab will continue to be administered biweekly and the LDL-apheresis procedure will be spaced from biweekly to monthly, the same analytical parameters being measured again every two weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures
