| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To evaluate the long-term safety and tolerability of TEZ/IVA in subjects with CF aged 6 years and older, who are homozygous or heterozygous for F508del |
|
| E.2.2 | Secondary objectives of the trial |
| To evaluate the long-term efficacy of TEZ/IVA in subjects with CF aged 6 years and older, who are homozygous or heterozygous for F508del |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Subject’s legally appointed and authorized representative will sign and date an informed consent form (ICF) and the subject will sign an assent form (if applicable).
2. Willing and able to comply with scheduled visits, treatment plan, study restrictions, laboratory tests, contraceptive guidelines, and other study procedures.
3. Completed the Week 24 Visit in Study 113 Part B or the Week 8 Visit in Study 115.
Added guidance:
- Subjects who had study drug interruptions, but completed study visits up to the last scheduled visit of the Treatment Period of the parent study, are eligible.
- Subjects who had a study drug interruption at the last scheduled visit of Study 113 Part B or Study 115, subjects who required study drug interruption that was to be continued or initiated at Day 1 in Study 116, or subjects who resumed study drug in the parent study after a study drug interruption due to elevated transaminases, but who did not complete at least 4 weeks of rechallenge with study drug (due to the timing of the rechallenge versus
the time remaining in the parent study), must meet eligibility criteria and receive approval from the Vertex medical monitor.
Note: Subjects who permanently discontinue study drug treatment during the parent study,
including at the last visit of the Treatment Period, are not eligible.
4. Did not withdraw consent from the parent study.
5. Subjects must have a genotype listed in Appendix 1: CFTR Mutations. Note: Additional mutations may be evaluated and updates to the list of eligible mutations will be communicated to investigative sites through a memorandum. If TEZ/IVA receives marketing authorization for additional mutations in any country/region for patients ≥12 years old, a memorandum will be sent to investigative sites in that country/region and the newly approved mutations will also be eligible.
6. Willing to remain on a stable CF medication regimen through the Safety Follow-up Visit. |
|
| E.4 | Principal exclusion criteria |
1. History of any comorbidity 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. For example, history of cirrhosis with portal hypertension, and/or history of risk factors for Torsade de Pointes (e.g., familial long QT syndrome, hypokalemia, heart failure, left ventricular hypertrophy, bradycardia, myocardial infarction, cardiomyopathy, history of arrhythmia [ventricular and atrial fibrillation], obesity, acute neurologic events [subarachnoid hemorrhage, intracranial hemorrhage, cerebrovascular accident, and intracranial trauma], and autonomic neuropathy).
2. Pregnant and nursing females. Females of childbearing potential must have a negative 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 outlined in Section 11.4.8 of the final Protocol V1.0.
4. History of drug intolerance in the parent study that would pose an additional risk to the subject in the opinion of the investigator, and which should be discussed with the Vertex medical monitor. Examples of subjects who may not be eligible for the study 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 parent study or other qualified Vertex study that required permanent study drug discontinuation
- 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 a previous study as deemed by the investigator.
6. Ongoing participation in another study with investigational drug. Ongoing participation in a non-interventional study (including observational studies) is permitted. During the Treatment Period, subjects may screen for another Vertex-sponsored study of CFTR modulators,
excluding studies of IVA monotherapy and lumacaftor in combination with IVA. If a subject chooses to enroll in the other Vertex-sponsored study, they will be terminated from Study 116 and will not be allowed to re-enroll in Study 116. |
