入选标准
- •1. Subject (or subject’s legally appointed and authorized representative) will sign and date an informed consent form (ICF), and, when appropriate, an assent form.
- •2. Willing and able to comply with scheduled visits, treatment plan, study restrictions, laboratory tests, contraceptive guidelines, and other study procedures.
- •3. Subjects will be aged 18 years or older for Parts 1 and 2, and aged 12 years or older for Part 4, on the date of informed consent and, when appropriate, date of assent.
- •4. Body weight =35 kg.
- •5. Sweat chloride value =60 mmol/L from test results obtained during screening. If the value cannot be determined from the screening test, a sweat chloride value documented in the subject’s medical record may be used to establish eligibility. (It is acceptable to use a sweat chloride value that was obtained before previous treatment with IVA, LUM/IVA, or an investigational CFTR modulator).
- •6. Subjects must have an eligible CFTR genotype as noted below. If the screening CFTR genotype result is not received before randomization (Parts 1 and 4) or before Day -28 (Part 2), a previous CFTR genotype laboratory report may be used to establish eligibility. Note: Subjects who have been randomized and whose screening genotype does not confirm study eligibility must be discontinued from the study (Section 9.5).
- •-Part 1 and Part 4: Heterozygous for F508del with a second CFTR allele carrying an MF mutation that is not likely to respond to TEZ and/or IVA therapy (Appendix A)
- •-Part 2: Homozygous for F508del
- •7. Parts 1, 2, and 4 subjects must have an FEV1 =40% and =90% of predicted normal for age, sex, and height (equations of the Global Lung Function Initiative [GLI]) at the Screening Visit. Spirometry measurements must meet American Thoracic Society/European Respiratory Society criteria for acceptability and repeatability.
- •8. Stable CF disease as judged by the investigator.
- •9. Willing to remain on a stable CF medication regimen through the planned end of treatment or, if applicable, the Safety Follow-up Visit.
- •Are the trial subjects under 18? yes
- •Number of subjects for this age range: 30
- •F.1.2 Adults (18-64 years) yes
- •F.1.2.1 Number of subjects for this age range 168
- •F.1.3 Elderly (>=65 years) no
- •F.1.3.1 Number of subjects for this age range
排除标准
- •1. History of any comorbidity that might confound the results of the study or pose an additional risk in administering study drug to the subject.
- •2. History of cirrhosis with portal hypertension.
- •3. Risk factors for Torsade de Pointes, including but not limited to, history of any of the following: familial long QT syndrome, chronic hypokalemia, heart failure, left ventricular hypertrophy, chronic bradycardia, myocardial infarction, cardiomyopathy, history of arrhythmia , obesity, acute neurologic events (subarachnoid hemorrhage, intracranial hemorrhage, cerebrovascular accident, or intracranial trauma), or autonomic neuropathy.
- •4. History of hemolysis.
- •5. G6PD deficiency, defined as G6PD activity less than the lower limit of normal (LLN) or 70% of the mean of the LLN and the ULN.
- •6. Any of the following abnormal laboratory values at screening:
- •-Hemoglobin <10 g/dL
- •-Total bilirubin =2 × ULN
- •-Aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), or alkaline phosphatase (ALP) =3 × ULN
- •-Abnormal renal function defined as glomerular filtration rate =50 mL/min/1.73 m2 for subjects =18 years of age and =45 mL/min/1.73 m2 for subjects aged 12 to 17 years
- •7. An acute upper or lower respiratory infection, pulmonary exacerbation, or changes in therapy (including antibiotics) for pulmonary disease within 28 days before the first dose of study drug (Day 1 for Parts 1 and 4, Day -28 for Part 2).
- •8. Lung infection with organisms associated with a more rapid decline in pulmonary status. For subjects who have had a history of a positive culture in the past, the investigator will apply the following criteria to establish whether the subject is free of infection with such organisms:
- •-The subject has had 2 respiratory tract cultures negative for these organisms within the past 12 months, with no subsequent positive cultures.
- •-These 2 respiratory tract cultures were separated by at least 3 months, and 1 of them was obtained within the past 6 months.
- •9. An acute illness not related to CF (e.g., gastroenteritis) within 14 days before the first dose of study drug (Day 1 for Parts 1 and 4, Day -28 for Part 2).
- •10. A standard digital ECG demonstrating QTc >450 msec at screening.
- •11. History of solid organ or hematological transplantation.
- •12. History or evidence of cataract or lens opacity determined to be clinically significant by the ophthalmologist or optometrist based on the ophthalmologic examination during the Screening Period.
- •13. History of alcohol or drug abuse in the past year, including but not limited to, cannabis, cocaine, and opiates, as deemed by the investigator.
- •14. Ongoing or prior participation in an investigational drug study with the exception of the following:
- •-Ongoing or prior participation in an investigational study of TEZ/IVA, IVA, LUM/IVA, or other CFTR modulator. For Parts 1 and 4, a washout period of 28 days must elapse before Day 1. Subjects participating in Study 661-110 may have the Part 1 or Part 4 Screening Period extended by 4 weeks (Section 8.1.1.3). For Part 2, a washout period before Day -28 is not required, and subjects participating in Study 661-110 will transition directly from their prior treatment to the TEZ/IVA Run-in Period providing that they meet eligibility criteria. For all parts, subjects participating in Study 661-110 may have their screening assessments performed while continuing to participate in Study 661-110.
- •-For prospective subjects
