•3.Subject has primary glomerulonephritis or secondary nephritis in addition to diabetic nephropathy.
•4.Subject has had acute renal failure within 12 weeks of the Screening Phase defined by an acute rise in serum creatinine (of at least 0.5 mg/dL or 44 mmol/L) to more than 4 mg/dL (350 mmol/L).
•5.Subject has chronic gastrointestinal disease, which in the Investigator's opinion may cause significant GI malabsorption.
•6.Subject has secondary hypertension (i.e., renal artery stenosis, primary aldosteronism or pheochromocytoma). 7.Subject has poorly controlled hypertension (systolic blood pressure ³ 160 mmHg and or diastolic blood pressure ³ 100 mmHg).
•8.Subject has a history of kidney stones.
•9.Subject has a history of drug or alcohol abuse within 6 months prior to the Screening Phase.
•10.Subject has evidence of poor compliance with diet or medication that may interfere, in the Investigator's opinion, with adherence to the protocol.
•11.Subject has received any investigational drug within 30 days prior to study drug administration. 12.Subject is taking calcitonin, bisphosphonates, cinacalcet, glucocorticoids (except topical glucocorticoids), or other drugs that may affect calcium or bone metabolism, other than calcium containing phosphate binder or female subjects on stable (same dose and product for 3 months) estrogen and/or progestin therapy.
•13.For any reason, subject is considered by the Investigator to be an unsuitable candidate to receive paricalcitol capsules or is put at risk by study procedures.
•14.Subject is known to be HIV positive.
