17. All subjects and/or parents/legal representative must have an understanding that pomalidomide could have a potential teratogenic risk. Female children of childbearing potential, defined as females who have achieved menarche and/or breast development in Tanner Stage 2 or greater and have not undergone a hysterectomy or bilateral oophorectomy and FCBP, defined as a sexually mature woman who has not undergone a hysterectomy or bilateral oophorectomy and has not been naturally postmenopausal for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months) must agree and meet the following conditions below:
-Medically supervised pregnancy tests with a sensitivity of at least 25 mIU/mL must be conducted in FCCBP/FCBP, including those who commit to true abstinence*.
Two pregnancy tests must be conducted prior to starting pomalidomide. The first pregnancy test must be performed 10 to 14 days prior to the start of pomalidomide and the second pregnancy test must be performed within 24 hours prior to starting pomalidomide. The subject may not receive pomalidomide until the Investigator has verified that the results of these pregnancy tests performed on Cycle 1, Day 1 are negative. Female children of childbearing potential/females of childbearing potential with regular or no menstrual cycles must agree to have pregnancy tests weekly for the first 28 days study participation, every 28 days while on study, at study treatment discontinuation visit, and at Day 28 following pomalidomide discontinuation. If menstrual cycles are irregular, the pregnancy testing must occur weekly for the first 28 days of study participation and then every 14 days while on study, at study treatment d
