2.7.4. Assessments (Date 14, Date 21).
ECTOPIC PREGNANCIES
A blood pregnancy test will be performed on the last day of study drug administration (V3). If serum hCG levels are below 20 IU/L, that is, biochemical pregnancy is not confirmed, the study will be terminated. In participants, who achieved biochemical pregnancy, transvaginal ultrasonography for confirmation of the fetal sac will be performed 1 week after completion of the protocol treatment (V4). When the fetal sac cannot be confirmed, another blood pregnancy test and ultrasound examination to confirm the fetal sac will be performed 1 week later (V5). If serum hCG levels at this time are higher than that at 2 weeks after ET (V3), even though the fetal sac is not confirmed, the patient should be followed up for suspected ectopic pregnancies.
