Study Population
Patients with Secondary HPT and ESRD who previously qualified for Amgen AM 073 studies but were withdrawn due to kidney transplant.

Inclusion Criteria:

- Patients who withdrew from one of the qualifying studies (i.e. patient previously took part in an Amgen study investigating the drug AMG 073 and its effects on secondary hyperparathyroidism [HPT]; in particular parathyroid hormone [PTH], calcium and phosphorus levels in blood associated with kidney failure) due to kidney transplantation.
