Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Absolute Change From Baseline in Percent-predicted Forced Expiratory Volume in One Second (ppFEV1) at Week 48 | The FEV1 is the volume of air forcibly exhaled in one second and is measured using forced expiratory air spirometry. Change in ppFEV1 at Week 48 was defined as the average between the change from baseline at Week 40 and that at Week 48. Baseline for ppFEV1 was defined as an average of ppFEV1 at Screening (Weeks -4 to -1) and Baseline (Day 1) visits. | From Baseline to Week 48 | |
Secondary | 48-week Rate of Pulmonary Exacerbations | Pulmonary exacerbations were assessed using expanded Fuchs criteria. The expanded Fuchs exacerbation is defined as the presence of at least 4 of 12 Fuchs' signs and symptoms requiring treatment with any form of antibiotic treatment (inhaled, oral, or intravenous). Fuchs' signs and symptoms included increased cough; change in sputum volume, color, or consistency; new or increased hemoptysis; increased dyspnea during moderate or mild exertion, or at rest; sinus pain or tenderness; change in sinus discharge; malaise, fatigue, or lethargy; anorexia or weight loss; temperature above 38 degrees Celsius; change in findings on chest examination; relative 10% decrease in ppFEV1, and chest radiography results consistent with pulmonary infection. The 48-week rate was calculated as: 48-week rate = total number of events /treatment duration by week*48. | Week 48 | |
Secondary | Change From Baseline in the Cystic Fibrosis Questionnaire - Revised (CFQ-R) Respiratory Domain at Week 48 | The teen/adult CFQ-R was used for this study. It was developed specifically for participants with cystic fibrosis. It is a disease-specific instrument designed to measure impact on overall health, daily life, perceived well-being, and symptoms. The respiratory domain assessed respiratory symptoms like coughing, congestion, wheezing etc. Scaling of each item is done via 4-point Likert scales. Scores for each item are summed up to generate a domain score. Scores ranges from 0 to 100, with higher scores indicating better health and lower scores indicating worse health. | Baseline (Day 1) and Week 48 | |
Secondary | Change From Baseline in Body Mass Index (BMI) at Week 48 | Malnutrition is common in participants with cystic fibrosis. The BMI is an important clinical measure of nutritional status. | Baseline (Day 1) and Week 48 | |
Secondary | Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (SAEs) | An adverse event (AE) is any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. A TEAE is defined as an AE that occurs or worsens in the period extending from first dose of study drug to 4 weeks after last dose of study drug. An SAE is an untoward medical occurrence or effect associated with the use of a study drug at any dose, regardless of whether it is considered to be related to the study drug, which results in one of the following: death; inpatient hospitalization or prolongation of existing hospitalization; life threatening adverse event; persistent or significant disability or incapacity or substantial disruption of the ability to conduct normal life functions; any other medically important event; or a pregnancy resulting in spontaneous abortion, stillbirth, neonatal death, or congenital anomaly. | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) | |
Secondary | Number of Participants With TEAEs by Severity and Relationship to Study Drugs | The relationship of TEAEs to the study drugs were assessed as: probable related, possibly related, unlikely related, and unrelated. The severity of TEAEs were graded using the Common Terminology Criteria for Adverse Events, Version 3.0 as: Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal). | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) | |
Secondary | Number of Participants With SAEs by Severity and Relationship to Study Drugs | The relationship of SAEs to the study drugs were assessed as: probable related, possibly related, unlikely related, and unrelated. The severity of SAEs were graded using the Common Terminology Criteria for Adverse Events, Version 3.0 as: Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal). | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) | |
Secondary | Number of Participants With Abnormal Vital Signs Reported as TEAEs | Vital signs included systolic and diastolic blood pressure, pulse rate, pulse oximetry, and body temperature. Participants with abnormal vital signs who required clinical intervention or further investigation (beyond ordering a repeat [confirmatory] test) unless they are associated with an already reported clinical event are reported. | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) | |
Secondary | Number of Participants With Abnormal Clinical Laboratory Parameters Reported as TEAEs | Clinical laboratory tests included haematology, biochemistry, and urinalysis. Participants with abnormal laboratory parameters who required clinical intervention or further investigation (beyond ordering a repeat [confirmatory] test) unless they are associated with an already reported clinical event are reported. | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) | |
Secondary | Number of Participants With Abnormal Electrocardiogram Reported as TEAEs | Participants with abnormal electrocardiogram who required clinical intervention or further investigation (beyond ordering a repeat [confirmatory] test) unless they are associated with an already reported clinical event are reported. | From study drug administration to 4-week post treatment follow-up visit (approximately 52 weeks) |
