Recent data now shows that certain double-barrier methods have a failure rate below 1% [Trussell, 2003]. Specifically, these are a spermicide plus a mechanical barrier (e.g., spermicide plus a male condom or a female diaphragm). This provides validated confirmation of the failure rate of the double-barrier method. Thus this method now meets the stated criterion for acceptable contraception in the EMEA guidelines [CPMP/ICH/285/95, 2000]; or Condom and occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository; or An intrauterine device (IUD) or intrauterine system (IUS), inserted by a qualified physician, with published data showing that the highest expected failure rate is less than 1% per year; (not all IUDs meet this criterion) Acceptable IUDs: Tcu-380A (Paragard), TCU-380 Slimline (Gyne T Slimline), Tcu-220C, MULTILOAD-250 (MLCu-250) and 375, NOVA T and CUNOVAT (Novagard), Levonorgesterol (LNG-20) Intra-uterine System (Mirena/Levonova), and FlexiGard 330/CuFix PP330 (Gynefix). The device must be inserted at least 2 weeks prior to the Screen visit, and remain throughout the study and through the follow-up phase of the study or Any other methods with published data showing that the highest expected failure rate is less than 1% per year.
