- Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, unless they are using effective methods of contraception throughout
the study and for 8 weeks after study drug discontinuation; highly effective
contraception methods include: total abstinence when this is in line with the
preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar,
ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable
methods of contraception; female sterilization (have had surgical bilateral
oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before
taking study treatment; in case of oophorectomy alone, only when the reproductive
status of the woman has been confirmed by follow up hormone level assessment; male
sterilization (at least 6 months prior to screening); for female patients on the

device (IUD) or intrauterine system (IUS) c. barrier methods of contraception: condom
or occlusive cap (diaphragm or cervical/vault caps) with spermicidal
foam/gel/film/cream/vaginal suppository; in case of use of oral contraception, women
should have been stable on the same pill before taking study treatment; note: oral
contraceptives are allowed but should be used in conjunction with a barrier method of
contraception; women are considered post-menopausal and not of child bearing potential
if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate
clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had
surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at
least six weeks ago; in the case of oophorectomy alone, only when the reproductive
status of the woman has been confirmed by follow up hormone level assessment is she
considered not of child bearing potential
- Sexually active males unless they use a condom during intercourse while taking the
drug and for 21 days after stopping treatment and should not father a child in this
period; a condom is required to be used also by vasectomized men in order to prevent
delivery of the drug via seminal fluid
- Patients unwilling or unable to comply with the protocol
- Patient is currently receiving warfarin or other coumarin-derived anticoagulant for
treatment, prophylaxis or otherwise; therapy with heparin, low molecular weight
heparin (LMWH) or fondaparinux is allowed
