Title: A 2 Year Prospective, Multicentre, Open-label, Randomised, Controlled Study to Investigate the Effectiveness of Pamidronate in the Prevention of Bone Loss in de Novo Renal Transplant Patients (With a PTH > 150pg/ml) on a Ciclosporin A and Glucocorticoid Based Immunosuppressive Regimen.
Brief Summary: The purpose of the study was to evaluate the effect of Pamidronate on bone mineral density loss and fracture rates up to 2 years, in post renal-transplant subjects on a Ciclosporin A and glucocorticoid based immunosuppressive regimen.


Options:
A: Inclusion Criteria:

1. First or second kidney transplant recipients, aged 18-75 years, PTH \> 150 pg/ml
2. De novo patients scheduled to receive ciclosporin A and prednisolone based immunosuppression.

Exclusion Criteria:

1. Previous or current bone disease unrelated to end stage renal failure.
2. Patients with PTH \< 150pg/ml who may be at risk of adynamic bone disease.
3. Treatment at any time with a bisphosphonate.
4. d. Calcitonin treatment during the previous month.
5. Malignancy (current or history within last 5 years)
6. Pregnancy or lactation, or women of childbearing potential unwilling to use an effective form of contraception for the 12 month duration of the study.

Protocol-defined inclusion/exclusion criteria may apply.
B: The key inclusion criteria are:

1. Male or female adult de novo kidney, kidney-pancreas or kidney-islet, or kidney-liver transplant recipients
2. Functioning graft within 28 days after transplantation (creatinine having decreased to \<200 micromol/l without the need for dialysis)
3. Being on standard triple immunosuppression including a calcineurin antagonist (cyclosporine or tacrolimus), mycophenolate (MMF or MPA) and steroids, with or without induction treatment with basiliximab or anti-thymocyte globulin

Key exclusion criteria are:

1. Age \<18 years
2. Rising creatinine after initial drop \<200 micromol/l or creatinine \>200 micromol/l at baseline
3. Evidence of early acute rejection, either suspected clinically and/or proven by biopsy
4. Presence of severe osteoporosis as evidenced by a T score \<-4 at the hip, femoral neck or any of the 4 vertebrae L1 to L4
5. Evidence of severe hyper- or hypoparathyroidism (iPTH \>800 ng/l or \<10 ng/l)
6. Hypocalcemia (total calcium \<1.8 mmol/l) or hypercalcemia (total calcium \>2.7 mmol/l)
7. Steroid-free de novo immunosuppression scheme
C: Inclusion Criteria:

* Patients with a renal graft having been transplanted within the previous 8 years and being at least 3 months post transplantation, or, patients scheduled to undergo transplantation from a living organ donor within the upcoming 3 months
* Venous serum bicarbonate concentration \< 24 mmol/L at time of baseline determination
* Renal transplant function with a calculated glomerular filtration rate (GFR) greater or equal 30 ml/min according to the Cockcroft-Gault formula
* Immunosuppressive therapy including a calcineurin inhibitor (cyclosporine A or tacrolimus)
* Age 20 through 65 years of either sex
* Written informed consent for study participation

Exclusion Criteria:

* Acute rejection episode requiring specific therapy within 4 weeks before study inclusion
* Severe impairment in general health and/or physical handicaps (malignant neoplasia, catabolic state, acute systemic infection requiring therapy)
* Mental illness, psychiatric disorder
* Tetracycline intolerance
* Planned or "overt" pregnancy
D: Inclusion Criteria: Chronic Kidney Disease patients not receiving dialysis with: - An iPTH greater than 100 pg/mL \[10.6 pmol/L\] for subjects with stage 3 CKD or greater than or equal to 160 pg/mL \[17.0 pmol/L\] for subjects with stage 4 CKD; - A serum calcium greater than 9.0 mg/dL \[2.25 mmol/L\]; - An estimated GFR less than or equal to 59 mL/min and greater than or equal to 15 mL/min. Exclusion Criteria: - Have an unstable medical condition, defined as having been hospitalized within 30 days before day 1, or otherwise unstable in the judgment of the investigator. - Experienced a myocardial infarction (MI) within 3 months before day 1. - Likely to initiate dialysis (in the opinion of the investigator) or are scheduled to undergo renal transplantation within 28 weeks after day 1. - Received active vitamin D therapy (i.e., 1-hydroxylated metabolites of vitamin D) for less than 30 days before day 1 or required a change in active vitamin D brand or dose level within 30 days before day 1 (for patients prescribed active vitamin D).
