3. Patients who can tolerate a hemodialysis treatment with blood flow rates of 300 ml per minute.
4. Female volunteers who are not documented to be surgically sterile must be willing to abstain from sexual intercourse during the study or be willing to use intrauterine devices or 2 forms of barrier contraception for at least 7 days prior to the initial dose of study medication and continuing through the completion of the study.
