Outcomes

Primary Outcome Measures

Number of Adverse Events
Safety as measured by number of adverse events, defined as any untoward medical occurrence in a subject who has been administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

Secondary Outcome Measures

Seattle Angina Questionnaire
The Seattle Angina Questionnaire is a quality-of-life measure for patients with coronary artery disease. The SAQ is a self-report instrument with 19 items that yields five subscale scores: physical limitation, angina stability, angina frequency, treatment satisfaction, and disease perception. The possible range of scores for each of the five subscales is 0 to 100, with higher scores indicating better quality of life. There is no summary score generated.

5. Study Description

Brief Summary
Experimental models have linked lipid lowering therapies with systemic inflammation; however, relatively little is known about this network in clinical populations and specifically how it changes with PCSK9 inhibition. The eligible subjects will have 6 visits in 13 to 16 weeks and will have Repatha/placebo 140mg subcutaneous every 4 weeks for 3 times since randomization visit, blood tests will be done in each visit to evaluate the effects of evolocumab upon biocellular markers potentially altered by PCSK9 inhibition in a population of type 2 diabetes patients with microvascular dysfunction. Primary Aims: Determine the ACUTE and SHORT-TERM effects of PCSK9 inhibition with evolocumab on biocellular markers of inflammation, immune mediated thrombosis and rheology. The data from this trial will be used to support a clinical trial to assess the role of PCSK9 inhibition in type 2 diabetes patients with cardiac microvascular dysfunction. Secondary Aims: To define the association between PCSK 9 concentrations and immune-related phenotype. To define the association between Lp(a) concentrations, oxidized phospholipids (OxPL), ApoB, biocellular markers of inflammation, tissue factor and immunothrombosis.
Detailed Description
Multi-center, double-blind, randomized, placebo-controlled, parallel group Phase IV study with two treatment arms: evolocumab SC 420 mg/dL QM or matching placebo. The population will include 40 participants with documented Atherosclerotic Vascular Disease (CAD, Stroke, PAD) and type 2 diabetes who receive treatment with maximal tolerated statin therapy and stable doses of anti-hyperglycemic therapy. Subjects will be followed for 12 weeks during the treatment phase, maintaining the double-blind throughout. Assessments of ACUTE and SHORT-TERM effects of PCSK9 inhibition with evolocumab on biocellular markers of endothelial function will be measured at baseline, Week 2, and Week 12. Safety assessments will be undertaken at each study visit.
