Criteria

Inclusion Criteria:

  • Are male or female adults who are:

    • With Child-Pugh Hepatic Dysfunction Stage A or B, or
    • With Moderate Renal Disease or
    • Healthy subjects matched to those who are enrolled in this study
  • Subjects who are considered to have only clinically non-significant conditions, as judged by the Principal Investigator and based on physical examination, laboratory profiles, medical history and ECG.
  • Female subjects who are not surgically sterile (i.e., having had a hysterectomy, bilateral oophorectomy or tubal ligation) or who are not at least 2 years naturally postmenopausal must agree to use an acceptable form of contraception.
  • Provide voluntary consent in writing to participate in this study.

Exclusion Criteria:

  • Subjects with known or suspected ileus, severe ulcerative colitis, gastrointestinal obstruction, gastric retention, bowel perforation, toxic colitis, or megacolon.
  • Subjects with impaired consciousness that predisposes them to pulmonary aspiration.
  • Subjects who, in the opinion of the Principal Investigator, have uncontrolled clinically significant pre-existing electrolyte disturbances, based on the Screening visit laboratory results.
  • Subjects with present or prior NYHA Functional Classification grade III or IV congestive heart failure.
  • Subjects who are pregnant or lactating, or intending to become pregnant during the study.
  • Subjects of childbearing potential who refuse a pregnancy test.
  • Subjects who have participated in an investigational clinical, surgical, drug, or device study within the past 30 days.
  • Subjects with a history of allergic or adverse response to any BLI-800 component.
  • Subjects who donated more than one pint of blood within 30 days prior to the study.
  • Subjects who donated plasma within 7 days prior to the study.
  • Subjects who had an abnormal diet or substantial changes in eating habits within 30 days prior to the start of the study.
  • Subjects who have had a bowel cleansing procedure within the past month or who have taken a laxative within the 5 days (120 hours) prior to dosing or who require a laxative every day.
  • Subjects who, in the opinion of the Investigator, should not be included in the study for any reason, including inability to follow study procedures.
