Study Endpoints
Primary Endpoints
Number of Study Participants Who Tolerated a Single Daily Oral ST-246 Dose as Determined by Safety Parameter Changes According to the DAIDS (Division of Acquired Immunodeficiency Syndrome) Adverse Events (AE) Grading Table.
Days 1 to 14; then 24, 48, 72, 96 and 120 hours and 4 weeks after final dose

Subjects were administered a single, daily oral dose of ST-246 (400 or 600 mg)and changes in safety parameteres were monitored. Safety parameters included adverse events, vital signs, physical examinations, laboratory tests (hematology, blood chemistry, and urinalysis) and electrocardiograms. The DAIDS AE grading table is a list of common terms and severity (intensity) of parameters used to describe adverse events occurring in NIAID-sponsored clinical studies/trials.
