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: 1. To define the association between PCSK 9 concentrations and immune-related phenotype. 2. To define the association between Lp(a) concentrations, oxidized phospholipids (OxPL), ApoB, biocellular markers of inflammation, tissue factor and immunothrombosis.

Eligibility Criteria

Inclusion Criteria

  • Subjects ≥18 years of age signing of informed consent;
  • A history of clinical ASCVD, which is defined as: acute coronary syndrome, or a history of MI, stable or unstable angina, coronary or other arterial revascularization, stroke, transient ischemic attack (TIA), or peripheral arterial disease presumed to be of atherosclerotic origin;
  • Clinical diagnosis of type 2 diabetes according to ADA/ CDA guidelines;
  • Subject on stable dose of maximally-tolerated statin therapy for ≥4 weeks prior to screening and LDL-c ≥70mg/dL. For subjects whose maximally tolerated dose of statin is no type or dose (i.e. determined to be statin intolerant by primary investigator), background lipid-lowering therapy is not required;
  • Fasting triglycerides ≤400mg/dL (4.52mmol/L) by central laboratory at screening;
  • Willing and able to comply with scheduled visits, treatment plan, laboratory tests and other trial procedures;
  • Abnormal urinary Albumin Creatinine Ratio (ACR) as defined by an ACR ≥2;
  • Subject tolerates screening placebo injection.

Exclusion Criteria

  • Personal or family history of hereditary muscular disorders;
  • NYHA III or IV heart failure, or last know left ventricular ejection fraction (LVEF) 10%), newly diagnosed type 2 diabetes (within 6 months of randomization), or laboratory evidence of diabetes during screening (fasting serum glucose ≥126mg/dL [7.0mmol/L] or HbA1c ≥6.5% without prior diagnosis of diabetes;
  • Uncontrolled hypertension, defined as sitting systolic blood pressure (SBP) >160mmHg or diastolic BP (DBP) >100mmHg;
  • Subject who has taken a cholesterol easter transfer protein (CETP) inhibitor in the last 12 months prior to LDL-c screening, such as: anacetrapib, dalcetrapib or evacetrapib;
  • Treatment in the last 3 months prior to LDL-c screening with any of the following drugs: systemic cyclosporine, systemic steroids (e.g. IV, intramuscular [IM], or PO) (Note: hormone replacement therapy is permitted), vitamin A derivatives and retinol derivatives for the treatment of dermatologic conditions (e.g. Accutane); (Note: vitamin A in a multivitamin preparation is permitted). Topical retinol prescription and non-prescription derivatives or creams are permitted;
  • Uncontrolled hypothyroidism or hyperthyroidism as defined by thyroid stimulating hormone (TSH) 1.5 times the ULN, respectively, at screening. Potential subjects with TSH 3 times the ULN as determined by central laboratory analysis at screening;
  • Known active infection or major hematologic, renal metabolic, gastrointestinal or endocrine dysfunction in the judgment of the investigator;
  • Diagnosis of deep vein thrombosis or pulmonary embolism within 3 months prior to randomization;
  • Unreliability as a study participant based on the investigator's (or designee's) knowledge of the subject (e.g. alcohol or other drug abuse);
  • Currently enrolled in another investigational device or drug study, or less than 30 days since ending another investigational device or drug study(s), or receiving other investigational agent(s);
  • Female subject who has either (1) not used at least 1 highly effective method of contraception for at least 1 month prior to screening or (2) is not willing to use such a method during treatment and for an additional 15 weeks after the end of treatment, unless the subject is sterilized or postmenopausal;
  • Subject who is pregnant or breast feeding, or planning to become pregnant during treatment and/ or within 15 weeks after the end of treatment;
  • Use of PCSK9 inhibitor within 10 weeks from screening;
  • Subject who has any kind of disorder that, in the opinion of the investigator, may compromise the ability of the subject to give written informed consent and/or to comply with all required study procedures;
  • Malignancy except non-melanoma skin cancers, cervical or breast ductal carcinoma in situ within the last 5 years;
  • Subject who has known sensitivity to any of the products or components to be administered during dosing;
