E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the effects of paricalcitol capsules on progression or regression of Left Ventricular Hypertrophy (LVH) in subjects with Stage 3B/4 Chronic Kidney Disease (CKD) compared to placebo as assessed by comparing changes in LV Mass Index (LVMI) over 48 weeks measured by sequential cardiac magnetic resonance imaging (MRI) |
|
E.2.2 | Secondary objectives of the trial |
1.Echocardiographic assessment of diastolic function, will be assessed by evaluating changes in diastolic mitral annular relaxation velocity (E') and changes in additional measures of diastolic function (IVRT, E/E', DT). 2. Changes in biological and inflammatory markers that have been linked to CVD in CKD subjects. Specifically, the markers to be evaluated will include plasma T3, IL-6, troponin-T, BNP and hsCRP. |

E.3 | Principal inclusion criteria |
To be eligible for participation, subjects must meet all of the following criteria: 1. Subject has voluntarily signed and dated an informed consent form, approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC), after the nature of the study has been explained and the subject has had the opportunity to ask questions. The informed consent must be signed before any study-specific procedures are performed. 2. Male or female subjects between 18 and 75 years. 3. For entry into the Treatment Period the subject must satisfy the following criteria based on the Screening laboratory values:· Estimated GFR between 15-50 ml/min/1.73m2 by simplified 4-variable Modification of Diet Renal Disease (MDRD) formula (this includes a 10% variation in the upper limit of eGFR that will be allowed for the enrollment of subjects, this is to account for variability in the creatinine assay).· Serum iPTH value between 50-300 pg/ml.· Corrected serum calcium level 8.0-10.0 mg/dL (2.0-2.5 mmol/L).· Phosphorous level £ 5.2 mg/dL (1.68 mmol/L).· Serum albumin ³ 3.0 g/dL (30 g/L).· Negative serum pregnancy test for female subjects of childbearing potential. 4. For entry into the Treatment Period the subject must satisfy the following criteria based on the Screening echocardiogram:· For females, LV ejection fraction ³ 50% and septal wall thickness between 12-15 mm; and,· For males, LV ejection fraction ³ 50% and septal wall thickness between 13-16 mm. 5. In the opinion of the investigator, the subject must be receiving optimal medical management of left ventricular hypertrophy and CKD including appropriate use of RAAS inhibitors (ACEi, ARB, or aldosterone inhibitor) if indicated by the subject's medical condition. 6. If the subject is receiving RAAS inhibitors the dose must have been stable for at least three months prior to the Screening Period. However, subject may have switched to different brands but at equivalent doses as determined by the study physician during the three months prior to the Screening Period. 7. Subject must have a technically adequate baseline cardiac MRI. 8. If female, subject is not breast feeding or is not pregnant (verified by negative pregnancy test prior to the Treatment Period); or is not of childbearing potential, defined as postmenopausal for at least one year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy); or is of childbearing potential and practicing one of the following methods of birth control:· Double-barrier method (condoms, contraceptive sponge, diaphragm, vaginal ring with spermicidal jellies or creams, or intrauterine device [IUD])· Hormonal contraceptives (oral, parenteral, or transdermal) for at least three months prior to and during study drug administration· Maintains a monogamous relationship with a vasectomized partner· Total abstinence from sexual intercourse during the study (minimum one complete menstrual cycle prior to study start) |
