Ext. Long-term Safety Study in CF Patients: Single Arm TIP

An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not related to study drug. A SAE was defined as an event which was fatal or life threatening, required or prolonged hospitalization, was significantly or permanently disabling or incapacitating, constituted a congenital anomaly or a birth defect, or encompassed any other clinically significant event that could jeopardize the participant or require medical or surgical intervention to prevent one of the aforementioned outcomes. Based on the severity, AEs were categorised into 3 types as mild, moderate and severe. Death was a fatal event leading to permanent cessations of all vital functions of the body.

FEV1 was defined as the volume of air expired in 1 second. FEV1 was assessed as a pulmonary function by using spirometry tests in accordance with American Thoracic Society/European Respiratory Society (ATS/ERS) criteria. FEV1% predicted is a normalized value of FEV1 calculated using the Knudsen equation, based upon participant's age, gender and height. Relative change in FEV1 % predicted from baseline to pre-dose day X = ((pre-dose day*FEV1% predicted - baseline FEV1% predicted) / baseline FEV1 % predicted) x 100.

Microbiological data was collected to understand the direct impact of the drug on the pathogens. Sputum samples were cultured for the presence of three Pseudomonas aeruginosa (P. aeruginosa) biotypes measured were mucoid, dry and small colony variant. Absolute change was determined using the formula = (Post-baseline value- baseline value). If no P. aeruginosa was isolated for a visit, log10 colony forming units (CFU) was imputed with log10 (19) for all biotypes.

MIC was defined as the lowest concentration of an antimicrobial agent required to inhibit the visible growth of a microorganism after overnight incubation. Tobramycin MIC 50 and MIC 90 values were defined as the lowest concentration of tobramycin required to inhibit 50% and 90%, respectively, of the P. aeruginosa strains tested (mucoid,dry and small colony variant biotypes).

The rate of anti-pseudomonal antibiotics use were determined from the collection of concomitant medication during the study.

The total number of days with usage of new anti-pseudomonal antibiotic were determined.

Time to first usage of anti-pseudomonal antibiotic was determined using Kaplan Meier estimate. Participants without an event were censored at the date of the last available post-baseline measurement.

The percentage of the participants hospitalized due to serious respiratory-related AEs were determined during the study.

The total number of hospitalization days due to serious respiratory-related adverse events was analyzed using Kaplan-Meier estimate.

The day of first hospitalization due to serious respiratory-related adverse events was analysed using Kaplan Meier estimate.

FEV1 was defined as the volume of air expired in 1 second. FEV1 was assessed as a pulmonary function by using spirometry tests in accordance with American Thoracic Society/European Respiratory Society (ATS/ERS) criteria. Relative change in FEV1 % predicted was calculated by using the formula = 100 *(30-min post-dose value - pre-dose value) / pre-dose value.
