    General information about the trial
    Main objective of the trial
    The main objective of the study was to assess the safety of tobramycin inhalation powder (TIP) with respect to incidence of treatment emergent adverse events (AEs) over 12 treatment cycles (6 treatment cycles in the core study and 6 treatment cycles in the extension study).
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed. Rescue medications like anti-pseudomonal antibiotics, macrolides (anti-inflammatory regimen), bronchodilators, inhaled hypertonic saline, inhaled corticosteroids were allowed for pulmonary exacerbations as per the discretion of the investigator. If the subject’s condition/disease required the medications which potentially affected the systemic tobramycin levels, inhalation of study medication was continued only at the investigator’s discretion. The investigator provided follow-up medical care for all subjects who were prematurely withdrawn from the study, or referred them for appropriate ongoing care.

    Number of subjects with adverse events (AEs), serious adverse events (SAEs), AEs/SAEs leading to discontinuation of study drug and deaths over 12 treatment cycles [1]
    End point description
    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 subject 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. The analysis was performed in extension safety population, defined as all the subjects who entered the extension study and received at least one dose of study drug within the extension.

    Relative change from baseline in forced expiratory volume in one second (FEV1) percent predicted over 12 treatment cycles
    End point description
    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 subject’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. The analysis was performed in extension safety population, defined as all the subjects 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 subjects evaluable for this measure at specified time points for each group, respectively.

    Absolute change from baseline in Pseudomonas aeruginosa sputum density over 12 treatment cycles
    End point description
    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. The analysis was performed in extension safety population, who had P. aeruginosa sputum density values at both baseline and the given time point. The 'n' signifies those subjects evaluable for this measure at specified time points for each group, respectively.

    Absolute change from baseline in Pseudomonas aeruginosa density over 6 treatment cycles in extension study
    End point description
    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). The analysis was performed in extension safety population, who had P. aeruginosa sputum density values at both baseline and the given time point. The 'n' signifies those subjects evaluable for this measure at specified time points for each group, respectively.

    Reporting group description
    Subjects 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.
