Rationale: Immune checkpoint inhibitors (ICIs) are often highly effective anti-cancer therapies but predispose patients receiving this treatment to cardiovascular disease and thrombotic events. One of the mechanisms by which ICIs increase cardiovascular risk is by stimulation of inflammation and atherosclerosis. Statins (e.g., atorvastatin) are frequently prescribed and effective anti-atherogenic agents, which could provide protective effects on the cardiovascular system in this patient population whilst and after receiving ICI, minimizing cardiovascular sequelae. The objective of this study is to study if addition of atorvastatin prevents accelerated progression of atherosclerosis during ICI therapy. In addition, the investigators would like to study the effects of atorvastatin during ICI therapy on endothelial function, epicardial fat volume, and hemostatic and inflammatory parameters. The main study endpoint is the difference in percentage growth of total atherosclerotic plaque volume in the descending thoracic segment of the aorta between intervention and control group, expressed in indexed percentage growth /year. Secondary endpoints are differences in non-calcified and calcified plaque volume in the thoracic arteries and coronary arteries, epicardial fat volume, endothelial function, and quality of life. Exploratory endpoints include effect on hemostatic and inflammation markers, lipid levels, progression free survival, event free survival, and overall survival. Trial design Placebo controlled prospective randomised controlled trial. Trial population Melanoma patients who are scheduled to receive ICI therapy (nivolumab, pembrolizumab, or a combination of anti-PD1/ipilimumab; (neo)adjuvant, irresectable or metastasized melanoma) according to standard-of-care who are also eligible to initiate statin therapy. The intervention group receives atorvastatin 20mg daily together with ICI therapy. The control group receives placebo together with ICI therapy. Both groups will undergo two coronary and thoracic CT-scans. In addition, blood withdrawal will take place fourthly during the study. Furthermore, endothelial function will be assessed by means of the EndoPAT device at baseline and after one year of follow-up. Ethical considerations relating to the clinical trial including the expected benefit to the individual subject or group of patients represented by the trial subjects as well as the nature and extent of burden and risks: Patients in the intervention group will receive atorvastatin, of which safety and tolerability will be carefully monitored. Coronary atherosclerosis will be assessed via two coronary CT-scans, yielding a total limited extra radiation exposure of 4-10mSv. Blood withdrawal will be combined with regular blood withdrawal time points for standard care or will be withdrawn from the intravenous catheter for ICI administration. Vascular endothelial dysfunction will be assessed via Endothelial Peripheral Arterial Tonometry (EndoPAT) by recording finger arterial pulsatile volume change. This non-invasive method forms a minimal extra burden for participating patients. The investigators hypothesize that atorvastatin prevents accelerated progression of atherosclerosis and ameliorates ICI-induced vascular endothelial dysfunction.
