dyslipidemia of obesity intervention in teens

Conditions: Dyslipidemia; Obesity

Summary: this trial of pitavastatin will determine efficacy and safety in this high risk population and provide evidence for clinicians to target this treatable risk factor to achieve an impact on early atherosclerosis, and potentially achieve primary prevention of adult cardiovascular disease.

randomized, double-blind, placebo-controlled clinical trial of pitavastatin for 2 years comparing the effect of study drug versus placebo on vascular measures in at least 354 adolescents with excess adiposity and cdo (defined as high non-hdl-c + high triglycerides (tg)/hdl-c ratio or low hdl-c). enrollment will take place over 36 months.

Eligibility criteria:
inclusion criteria: * boys and girls aged 10 to 19 years (with 2-year availability for study participation) * bmi ≥85th percentile (using centers for disease control (cdc) bmi charts) * fasting lipid profile x2 each with all of the following: * ldl-c \<160 mg/dl and ≥90 mg/dl, and * tg (triglycerides) \<500 mg/dl, and * tg/hdl-c ratio ≥2.5 or hdl-c \<45 mg/dl for boys or hdl-c \<50 mg/dl for girls, and * non-hdl-c ≥120 mg/dl * participant consent, or parental/guardian consent and participant assent exclusion criteria: * current use of lipid lowering medication, growth hormone, systemic corticosteroids, cyclosporine, protease inhibitors, erythromycin, rifampin, colchicine, warfarin, second generation psychotropic drugs, oral isotretinoin; stable doses of stimulant or antidepressant therapy and antihypertensive medications will be accepted * known allergy or hypersensitivity to statin * patients who have had bariatric surgery or plan to have bariatric surgery during the trial * female who is pregnant, plans to become pregnant or is sexually active without contraception * uncontrolled stage 2 hypertension (systolic or diastolic blood pressure ≥95th percentile for age, sex and height percentile + 12 mmhg or ≥140/90, whichever is lower for participants \<13 years of age; ≥140/90 for participants ≥13 years of age) confirmed after an appropriate evaluation * diabetes (type 1 or type 2) by american diabetes association criteria (fasting glucose ≥126 mg/dl, hba1c ≥6.5%, random glucose ≥200 mg/dl, or 2-hour oral glucose tolerance testing glucose ≥200 mg/dl) * use of insulin sensitizing therapy * known renal insufficiency (known chronic renal disease, estimated glomerular filtration rate (gfr) \<60 ml/min/1.73m2 at screening) * uncontrolled thyroid disease (tsh at screening \>1.5x upper limit of normal, clinical or other laboratory evidence of hypothyroidism, or thyroid hormone therapy that has not been stable for 6 weeks prior to screening) * proteinuria suggestive of renal disease (more than trace together with an elevated urine protein:creatinine ratio as per local lab) * syndromic patients or patients with neurocognitive delay precluding adherence with study drug * liver disease other than non-alcoholic fatty liver disease (nafld) either diagnosed or suggested by alanine aminotransferase (alt) ≥ 40 u/l, or severe nafld indicated by alt ≥ 200 u/l * unexplained persistent elevated creatine kinase (ck) level \>3x upper limit of normal * plans to leave the geographic area before completion of the anticipated 2 years of trial participation * any unstable medical or emotional condition or chronic disease that would preclude following the protocol or impact valid vascular measurement * admits to current smoking, current alcohol consumption
