E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects who meet all of the following inclusion criteria will be eligible.
1.Subject’s legally appointed and authorized representative (e.g., parent or legal guardian) will sign and date an ICF and the subject will sign and date an assent form (if applicable).
2.Subjects entering the Treatment Cohort must meet both of the following criteria:
•Completed 24 weeks of study drug treatment in Study 109 or completed 24 weeks of study drug treatment and the Week 26 Safety Follow up in Study 011B
-Subjects who had study drug interruptions, but completed study visits up to Week 24 of Study 109 or Week 26 of Study 011B are eligible (this is Day 1 of Study 110 for subjects at Study 110 active sites). Subjects who are not taking study drug at the end of the Treatment Period
•Elect to enroll in the Treatment Cohort
NOTE: Subjects who prematurely discontinued study drug treatment are not eligible for enrollment in the Treatment Cohort.
Subjects entering the Observational Cohort must meet 1 of the following criteria:
•Completed 24 weeks of study drug treatment in Study 109 or completed 24 weeks of study drug treatment and the Week 26 Safety Follow up in Study 011B
•Subjects who received at least 4 weeks of study drug and completed visits up to Week 24 of Study 109 or Week 26 of Study 011B (this is Day 1 of Study 110 for subjects at Study 110 active sites) but are not taking study drug at the end of the Treatment Period.
•Subjects who permanently discontinued study drug after receiving at least 4 weeks of study drug and remained in the study from the time of discontinuation of study drug treatment through the Week 24 Visit in Study 109 or the Week 26 Visit of Study 011B.
3.Subjects who are willing to remain on a stable CF medication regimen through the Safety Follow up Visit (Treatment Cohort only).
4.As deemed by the investigator, the subject’s legally appointed and authorized representative (e.g., parent or legal guardian) must be able to understand protocol requirements, restrictions, and instructions. The subject’s legally appointed and authorized representative should be able to ensure that the subject will comply with, and is likely to complete, the study as planned.
|
|
E.4 | Principal exclusion criteria |
Subjects who meet any of the following exclusion criteria will not be eligible.
1.History of any comorbidity or laboratory abnormality that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering study drug to the subject (e.g., cirrhosis with portal hypertension).
2.Pregnant and nursing females. Females of childbearing potential must have a negative urine pregnancy test at the Day 1 Visit before receiving the first dose of study drug.
3.Sexually active subjects of reproductive potential who are not willing to follow the contraception requirements.
4.History of drug intolerance in the prior study that would pose an additional risk to the subject in the opinion of investigator, and which should be discussed with the Vertex medical monitor. Examples of subjects who may not be eligible for the treatment cohort include (but are not limited to) the following:
•Subjects with a history of allergy or hypersensitivity to the study drug
•Liver function test (LFT) abnormality during study drug treatment in the previous study (Study 109 or Study 011B) for which a clear cause was not identified:
oAbnormal liver function defined as any 2 or more of the following:
a.≥3 × upper limit of normal (ULN) aspartate aminotransferase (AST)
b.≥3 × ULN alanine aminotransferase (ALT)
c.≥3 × ULN gamma glutamyl transpeptidase
d.≥3 × ULN alkaline phosphatase
oALT or AST >5 × ULN
oTotal bilirubin >2 × ULN
oOther LFT abnormalities that would pose an additional risk to the subject in the opinion of investigator or Vertex
•Other severe or life-threatening reactions to the study drug in the previous study
5.History of poor compliance with study drug and/or procedures in the previous study as deemed by the investigator.
6.Participation in an investigational drug trial (including studies investigating lumacaftor and/or ivacaftor). NOTE: participation in a noninterventional study (including observational studies, registry studies, and studies requiring blood collections without administration of study drug) is permitted. |
