| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary objective is to evaluate the safety, tolerability, and efficacy for galicaftor/navocaftor/ABBV 119 combination therapy in adult subjects with CF who are homozygous or heterozygous for the F508del mutation. |
|
| E.2.2 | Secondary objectives of the trial |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Confirmed clinical diagnosis of CF, and genotype homozygous for the F508del CFTR mutation for Cohort 1 and Cohort 3, heterozygous for F508del CFTR mutation and a minimal function mutation for Cohort 2 and Cohort 3. 2. ppFEV1 ≥ 40% and ≤ 90% of predicted normal for age, gender, and height (Global Lung Function Initiative [GLI] equations) at Screening. 3. No clinically significant laboratory values at Screening that would pose undue risk for the subject or interfere with safety assessments (per the investigator). 4. Absence of clinically significant abnormality detected on ECG regarding rate, rhythm, or conduction (e.g., QT interval corrected for heart rate using Fridericia's formula [QTcF] should be < 450 msec for males and < 460 msec for females). 5. Stable pulmonary status, i.e., no respiratory infections or exacerbations requiring a change in therapy (including antimicrobials) or causing an acute decline in ppFEV1 of >10% from usual ppFEV1 level within 4 weeks. 6. SwCl at screening visit must be ≥ 60 mmol/L for Cohort 1 and Cohort 2, and this criteria does not apply to Cohort 3. 7. No history of diseases aggravated or triggered by ultraviolet radiation and no history of abnormal reaction photosensitivity or photoallergy to sunlight, or artificial source of intense light, especially ultraviolet light. |
|
| E.4 | Principal exclusion criteria |
1. Cirrhosis with or without portal hypertension (e.g., splenomegaly, esophageal varices) or history of clinically significant liver disease. 3. History of malignancy within past 5 years (except for excised basal cell carcinoma of the skin with no recurrence, or treated carcinoma in situ of the cervix with no recurrence). 4. Recent (within the past 6 months) history of drug or alcohol abuse that might preclude adherence to the protocol, in the opinion of the investigator. 5. Smoking or vaping tobacco or cannabis products within 6 months before Screening. 6. History of solid organ or hematopoietic transplantation. 7. History of known sensitivity to any component of the study drug. 8. Need for supplemental oxygen while awake, or > 2 L/minute while sleeping. 10. Evidence of active SARS-CoV-2 infection. If a subject has signs/symptoms suggestive of SARS CoV-2 infection, they should undergo molecular (e.g., polymerase chain reaction [PCR]) testing to rule out SARS-CoV-2 infection. Subjects who do not meet SARS-CoV-2 infection eligibility criteria must be screen failed and may only rescreen after they meet the SARS-CoV-2 infection viral clearance criteria listed in the protocol. |
