a) Surgical sterilization (e.g. bilateral tubal ligation, hysterectomy).
b) Hormonal contraception (implantable, patch, oral, injectable).
c) Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/cream/suppository.
d) Continuous abstinence.
Periodic abstinence (e.g. calendar, ovulation, symptom-thermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. Reliable contraception should be maintained throughout the study and for 30 days after study drug discontinuation.

•Andere aandoeningen die de resultaten van de studie kunnen verstoren in de ogen van de onderzoeker.
•Zwangere vrouwen of vrouwen die borstvoeding geven.
•Geen adequate conceptie. Onder adequate anticonceptie wordt verstaan:
a) Post-menopausal: > 12 maanden spontane amenorrhoe of > 6 maanden amenorrhoe met een serum FSH < 40 mIU / mL.
b) Chirurgische sterilisatie (e.g. bilaterale tuba ligatie, hysterectomy).
b) Hormonale contraception (implantable, patch, oral, injectable).
c) Barrier methode: condoom.
d) Volledige abstinentie.
