study of ssp-004184 (fbs0701) in healthy adults and elderly subjects and in subjects with impaired renal function

Conditions: Impaired Renal Function

Summary: shire is developing ssp-004184 (fbs0701), a novel iron chelator , for the treatment of chronic iron overload in patients with transfusion-dependent hereditary and acquired anemias. the primary purpose of the study is to assess the pharmacokinetics of ssp-004184 (fbs0701) following a single 75mg/kg dose of ssp-004184 (fbs0701) in healthy adults and elderly subjects and in adult subjects with mild, moderate, severe, and end stage renal disease (esrd) degrees of impaired renal function. the results of this study will characterize the pharmacokinetics, safety, and tolerability of ssp-004184 (fbs0701) in adult subjects with various degrees of renal impairment, and these data will be compared to healthy adult and elderly subjects.

the upper limit of normal (uln). subjects with renal impairment * current or recurrent disease, other than impaired renal function that could affect, the action, absorption or disposition of the investigational product, or clinical or laboratory assessments. * concurrent chronic or acute illness or unstable medical condition (other than those associated with their renal disease) that may deteriorate and thus confound the results of safety assessments, increase risk to the subject or lead to difficulty complying with the protocol. * a potassium concentration \>6.2 mmol/l at the screening visit. * subjects with a renal transplant. * history of nephrotic syndrome (defined as plasma albumin \ 3 g/day), or other metabolic endocrine disease known to be associated with alterations in plasma lipid levels (uncontrolled hypothyroidism defined as tsh 1.5 times greater than the upper reference range value). * subjects on peritoneal dialysis. * uncontrolled systolic or diastolic blood pressure as defined by the investigator. * liver enzymes (alt, ast, ggt) more than 2 fold above uln at the screening visit or on day -2. * uncontrolled diabetes mellitus as determined by the investigator. * congestive heart failure classified new york heart association (nyha) class iii or iv. * any major illness that would in the opinion of the investigator put study subject at risk or interfere with study conduct. all subjects * acute illness, as judged by the investigator, within 2 weeks of the first dose of investigational product. * known or suspected intolerance or hypersensitivity to the investigational products, closely related compounds, or any of the stated ingredients. * subject has a history of thyroid disorder that has not been stabilized on thyroid medication or treatment within 3 months of the screening visit. * history of alcohol or other substance abuse within the last year. * a positive screen for alcohol or drugs of abuse at the screening visit or on day -2. * male subjects who consume more than 3 units of alcohol per day. female subjects who consume more than 2 units of alcohol per day. one alcohol unit=1 beer (12 oz/355 ml) = 1 wine

of any other medication (including over-the-counter, herbal or homeopathic preparations) that could affect (improve or worsen) the condition being studied, or could affect the action, absorption, or disposition of the investigational product(s), or clinical or laboratory assessment. (current use is defined as use within 14 days of dosing). subjects must be on a stable dose of allowed medications for 14 days prior to dosing. * use of tobacco in any form (eg, smoking or chewing) or other nicotine-containing products in any form (eg, gum, patch) within 30 days prior to the first dose of investigational product. * routine consumption of more than 2 units of caffeine per day or subjects who experience caffeine withdrawal headaches or have a history of caffeine withdrawal headaches.
