who are nil by mouth for any reason (eg, elective surgery or medical procedure, TPN
feeding, gastrointestinal disturbance etc) may also be included in the study provided
they are haemodynamically stable (see Inclusion Criterion 4) and the 6 hour period of
blood pressure and pulse monitoring in the study does not interfere with any planned
medical or surgical intervention.

- Evidence of a personally signed and dated informed consent document indicating that
the subject has been informed of all pertinent aspects of the study.

- Subjects who are willing and able to comply with scheduled visits, treatment plan and

Characteristics (SmPC).

- Other severe acute or chronic medical or psychiatric condition that may increase the
risk associated with study participation or investigational product administration or
may interfere with the interpretation of study results and, in the judgment of the
investigator, would make the subject inappropriate for entry into this study.

ritonavir) within the previous 1 month of screening.
