Are the trial subjects under 18? yes
Number of subjects for this age range: 140
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 710
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range
1.New development of a comorbidity during the parent study that might post an additional risk in administering study drug to the subject. This includes, but is not limited to, the following:
- Hepatic cirrhosis with portal hypertension, moderate hepatic impairment, or severe hepatic impairment, that might pose an additional risk in administering study drug to the subject.
- Solid organ or hematological transplantation.
- Any other comorbidity that, in the opinion of the investigator, might post an additional risk in administering study drug to the subject.
2.Pregnant or breast-feeding females. All female subjects must have a negative pregnancy test at the Day 1 Visit before receiving the first dose of study drug.
3.History of drug intolerance in a parent study that would pose an additional risk to the subject in the opinion of the investigator. (e.g., subjects with a history of allergy or hypersensitivity to the study drug.)
4.Current participation in an investigational drug trial (other than a parent study). Participation in a noninterventional study (including observational studies, registry studies, and studies requiring blood collections without administration of study drug) and screening for another Vertex study is permitted.
5.The subject or a close relative of the subject is the investigator or a subinvestigator, research assistant, pharmacist, study coordinator, or other staff directly involved with the conduct of the study at that site.
However, an adult (aged 18 years or older) who is a relative of a study staff member may be enrolled in the study provided that
- the adult lives independently of and does not reside with the study staff member, and
- the adult participates in the study at a site other than the site at which the family member is employed.
