          -  Each subject will be given a serum pregnancy test as part of the pre-study screening

          -  Adequate blood and urine samples should be obtained within 28 days before beginning of
             the first period and at the end of the trial for clinical laboratory measurements.

          -  Clinical laboratory measurements will include the following:

               -  Hematology: hemoglobin, hematocrit, red blood cell count, platelets, and white
