             (ECG) and laboratory investigations must be clinically acceptable or within laboratory
             reference ranges for the relevant laboratory tests, unless the investigator considers

                  post-menopausal women, the value of the serum pregnancy test may be slightly
                  increased. This test will be repeated to confirm the results. If there is no
                  increase indicative of pregnancy, the female will be included in the study.

               -  Of childbearing potential, the following conditions are to be met:

          -  Negative pregnancy test If this test is positive, the subject will be excluded from
             the study. In the rare circumstance that a pregnancy is discovered after the subject

             must agree to use an accepted method of contraception, and agree to continue with the
             same method throughout the study An example of a reliable method of contraception is a
             non-hormonal intrauterine device. In this study the concomitant use of hormonal
             contraceptives is NOT allowed. Other methods, if considered by the investigator as

             participate in the study.

        Exclusion Criteria:

          -  Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional
             or intellectual problems likely to limit the validity of consent to participate in the
