If rial participants do not have a negative test result for LSIL, HSIL or malignancy in the past 12 months, PAP smear/tests in accordance with the Bethesda classification will be performed during screening. In circumstances where the results of the PAP smear are pending at the time of randomization, eligible trial participants may be randomized. In the case of ASCUS result (previous or from screening), test should be repeated in first possible term.\n- Women must have a negative pregnancy test before randomization and may not be lactating or planning to become pregnant during the study period up to Long Term Follow Up Visit 5\n- Agreement of female trial participant of childbearing potential to use highly effective methods of contraception according CTGA vr. 1.2 07Mar2024 (method that can achieve a failure rate of <1% per year when used consistently and correctly e.g. combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation, progestin intrauterine device, all oral contraceptives, transdermal hormonal contraceptives with exception of spermicides, or diaphragms, intravaginal contraception) or to abstain from heterosexual intercourse from screening up to Long Term Follow Up Visit 5.
