Brief Summary

Phase I, open-label study in 15 healthy adult subjects receive 6 mg of auranofin orally once every 24 hours for 7days. Blood samples will be taken for 17 weeks following the last dose of auranofin for determination of terminal phase pharmacokinetic parameters. Stool samples will also be obtained for the measurement of gold.

Detailed Description

Auranofin is a gold-containing chemical salt, granted as an orphan drug status for use in the treatment of amebiasis. Amebiasis is a parasitic infection caused by the protozoon Entamoeba histolytica. It affects about ten percent of the world's population, being especially common in areas with poor health infrastructure. This is a Phase I open label, multiple dose study to evaluate the pharmacokinetics of Auranofin following oral dose administration for 7 days to healthy subjects. 15 healthy male and female volunteers age 18-45 years, inclusive enrolled in one site. The study duration is 48 weeks and up to 23 weeks of subject participation. The primary objective characterizes the pharmacokinetics of gold, given as auranofin, during and after 7 days of once daily oral dose administration. The secondary objective monitor the safety of Auranofin during and after 7 days of oral administration.

Occasional social smoking is acceptable. You must not change your use of tobacco from your first visit and through completion of the last visit of the study. -Treatment with an investigational drug within 30 days prior to study drug administration. -Prior exposure to gold-containing products. -Use of any prescription or nonprescription drugs, vitamins, or dietary or herbal supplements within 14 days prior to study drug administration. As exceptions, acetaminophen may be used at doses of </=1 g/day until 24 hours prior to study drug administration. -Blood donation of >/= 1 pint (473 mL) within 30 days prior to study drug administration. -Plasma and platelet donation within 14 days prior to study drug administration. -Screening liver function tests (alanine aminotransferase [ALT] or aspartate aminotransferase [AST]) greater than upper limit of normal (ULN). -Evidence of hepatitis B, hepatitis C or human immunodeficiency virus (HIV) infection upon serological testing at the Screening Visit. -Evidence of active infection or febrile illness (e.g., bronchopulmonary, urinary or gastrointestinal) within 7 days prior to study drug administration. -History of allergy to auranofin or any of the excipients in the capsules. (excipients per the package insert of auranofin are listed in Section 6.1) -Any other condition that, in the opinion of the investigator, poses a risk to the safety of the individual or the valid conduct of the study.
