Trial Outcomes & Findings for Ext. Long-term Safety Study in CF Patients: Single Arm TIP (NCT NCT01775137)

NCT ID: NCT01775137

Last Updated: 2015-11-06

Results Overview

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.

Measure
Tobramycin Inhalation Powder
Participants inhaled four capsules of tobramycin inhalation powder (28 mg) twice daily (bid) via the T326 inhaler device, for 28 days (treatment phase in each cycle). Each treatment phase therefore consisted of 112 mg tobramycin (4 capsules of 28 mg each) with the total daily dose of 224 mg tobramycin (112 mg bid).The treatment phase was followed by 28 days of no study treatment (off treatment in each cycle). These 56 days represented 1 cycle of therapy.

PRIMARY outcome

Timeframe: Baseline (start of study treatment in core study) to Day 673 (end of the extension study)

Population: The analysis was performed in extension safety population, defined as all the participants who entered the extension study and received at least one dose of study drug within the extension.

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.

Population: Extension safety population, defined as all the participants who entered the extension study and received at least one dose of study drug within the extension and had FEV1% values at both baseline and the post baseline time points. The 'n' signifies those participants evaluable for this measure at specified time points for each group, respectively.

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).

Population: The analysis was performed in extension safety population, who had microbiological data at specified time points. The 'n' signifies those participants evaluable for this measure at specified time points for each group, respectively.

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. If no P. aeruginosa was isolated for a visit, log10 colony forming units (CFU) was imputed with log10 (19) for all biotypes. Absolute change was calculated by using the formula = (Value at actual time point - start of extension value).

Measure
Core
n=45 participants at risk
Eligible participants were assigned to four capsules of TIP at 28 mg dosage strength, inhaled b.i.d. in the morning and in the evening via the T-326 inhaler, for 28 days (on treatment), followed by 28 days of no study treatment (off treatment). Each treatment therefore consisted of 112 mg tobramycin (4 capsules of 28 mg each) with the total daily dose = 224 mg tobramycin (112 mg b.i.d.). These 56 days represented 1 cycle of therapy during core study.
Extension
n=45 participants at risk
Participants inhaled four capsules of tobramycin inhalation powder (28 mg) bid via the T-326 inhaler device, for 28 days (treatment phase in each cycle). Each treatment phase therefore consisted of 112 mg tobramycin (4 capsules of 28 mg each) with the total daily dose of 224 mg tobramycin (112 mg bid). The treatment phase was followed by 28 days of no study treatment (off treatment in each cycle). These 56 days represented 1 cycle of therapy.
Overall
n=45 participants at risk
All participants who inhaled tobramycin inhalation powder during both core and extension study.
