E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine if the [11C]PK11195 BPnd, as a measure of neuroinflammation, in schizophrenic patients is decreased after simvastatin treatment. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to compare [11C]PK11195 BPnd between schizophrenic patients and healthy controls and to correlate the [11C]PK11195 BPnd with the outcome measures of the core trial. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Control subjects > Age between 18 and 50 years.
Schizophrenic patients > Age between 18 and 50 years > A DSM-IV-R diagnosis of: 295.x (schizophrenia, schizophreniform disorder, or schizoaffective disorder) or 298.9 (psychosis NOS) > Onset of first psychosis no longer than 3 years ago; > Female patients of childbearing potential need to utilize a proper method of contraception (the pill, vaginal ring, hormonal patch, intrauterine device, cervical cape, condom, contraceptive injection, diaphragm) in case of sexual intercourse during the study. |

Schizophrenic patients > Fulfilment of criteria of statin prescription; according to the Dutch Heart Foundation (Hartstichting), statin treatment is indicated when the total cholesterol level is > 8 mmol/l (www.hartstichting.nl) > Presence of any of the contra-indications or warnings for the use of simvastatin as reported in the SPC > Chronic use of glucocorticosteroids (temporary use is permitted, if stopped at least 1 month before start of treatment trial) > Chronic use of non-steroidal anti-inflammatory drugs (temporary use is permitted, if stopped at least 1 month before start of treatment trial) > Current use of statins or other lipid-lowering drugs > Pregnancy or breast-feeding > Active liver, kidney or muscle disease as defined by alanine aminotransferase (ALAT), creatinine or creatine kinase (CK) levels more than two times the upper boundary of normal levels > Use of comedication that either inhibits or induces the live enzyme CYP3A4 which is responsible for the degradation of simvastatin. Inhibitors of CYP3A4 include itraconazole, ketoconazole, posaconazole, fluconazole, erythromycin, clarithromycin, telithromycin, HIV protease inhibitors, nefazodone, telaprevir, boceprevir, imatinib, ticagrelor, voriconazole; inducers of CYP3A4 include carbamazepine, efavirenz, nevirapin, etravirin (can be washed out before start of trial) > Use of comedication that may increase the risk for myalgia, rhabdomyolysis and myopathy, including colchicine, bosentan, fenobarbital, fenytoin, hypericum, rifabutin, rifampicin, fibrates (e.g. gemfibrozil), fusidic acid, carbamazepine (can be washed out before start of trial) > Use of non-steroidal anti-inflammatory drugs (NSAIDs) one week before the PET scan; > Alcohol or substance abuse in the past 3 months; > Participation in a scientific research study during the past year involving radiation. |
