Abstract

Inclisiran is the first silencing–RNA therapy used to reduce LDL–C. It is also recommended in patients with statin intolerance. We describe a case series of three no–responder patients to inclisiran.

64–year–old man with medical history of type II diabetes mellitus, obesity, hypertension, chronic kidney disease (eGFR 38 ml/min/1.73 m^2), dyslipidemia and statin intolerance. In 2022 the coronary angiography showed diffuse atherosclerosis without significant stenosis. His LDL–c was 115 mg/dl. Rosuvatatin 10 mg was prescribed however it was withdrawn due myalgia. Inclisiran and ezetimibe were prescribed, however one, three and four months later his LDL–C was 96 mg/dl, 114 mg/dl, and 115 mg/dl respectively (Fig 1). Due to the lack of effect, lovastatin 20 mg was added after the third dose of inclisiran, reaching LDL–C levels of 100 mg/dl one month after the initiation of lovastatin. Inclisiran was withdraw (as well as statin due to myalgia) and evolocumab 140 mg was administrated three months later the last dose of inclisiran. Ten days after evolocumab, LDL value was 66 mg/dl. 60–year–old man with hypertension, obesity, and dyslipidemia (LDL 152 mg/dl) with a moderate cardiovascular risk (target LDL–C <70 mg/dl). Patient refused statin therapy because he was scared about myalgia. In October 2021 (first Italian patient out of clinical trial) inclisiran was administrated. However, LDL–C did not change one month after the first and the second dose (147 mg/dl and 134 mg/dl…

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
