Single Dose Pharmacokinetics of Oral Dextran Sulfate (UA001) and Intravenous Dextran Sulfate in Healthy Volunteers

This study has been completed.

Sponsored by:	National Institute of Allergy and Infectious Diseases (NIAID)
Information provided by:	National Institute of Allergy and Infectious Diseases (NIAID)
ClinicalTrials.gov Identifier:	NCT00000690

Purpose

To evaluate how the drug dextran sulfate (DS) is absorbed by the stomach and intestines when taken by mouth. To evaluate its effect on blood coagulation.

DS has been reported to have anti-HIV activity. However, it is not known how much of the drug is absorbed into the bloodstream and can be used by the body when DS is taken by mouth.

Detailed Description:

DS has been reported to have anti-HIV activity. However, it is not known how much of the drug is absorbed into the bloodstream and can be used by the body when DS is taken by mouth.

On 2nd day of hospitalization, each volunteer receives an oral dose of DS. Over the next 24 hours, 15 blood samples are obtained (from 15 separate needle sticks). On 4th day, each volunteer is given an injection of DS into vein. 18 blood samples are obtained. Blood is withdrawn before the infusion, at the end of the infusion, and 30 and 60 minutes after the infusion. All urine is collected.
