- Female subject who is pregnant, lactating or planning pregnancy during the course of the study and for 3 months from the date of last dose.
- Female subjects of child bearing potential, unless willing to use two forms of contraception, one of which must be a barrier contraception (e.g. Female condom of occlusive cap (diaphragm or cervical vault/caps) with spermicide) during the study and for 3 months from the date of last dose (however a male condom should not be used in conjunction with the female condom).
- Male subjects whose partner is of child bearing potential, unless willing to use an appropriate barrier method of contraception (condom and spermicide) in addition to having their female partner use another form of barrier contraception (e.g. occlusive cap (diaphragm or cervical vault/caps) with spermicide) during the study and for 3 months from date of last dose (however a male condom should not be used in conjunction with a female condom).
- Received an Investigational Medicinal Product within the 90 days before the screening visit (Visit 1).
- In the opinion of the investigator, is not considered to be suitable for the study.
- Poor compliance as observed during screening period.
- Any other significant disease or disorder which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, influence the result of the study, or the subject's ability to participate in the study.
- Any abnormalities identified during the physical examination at Visit 1 that in the opinion of the investigator would prevent the subject from safe participation in the study.
- Unwilling to abstain from donation of blood during the study.
- Previously randomised into this study.
