Interventions
Each patient will be randomised in a (1:1) ratio to receive either 2 x 170 mg/day T100/ Pari eFlow® or 2 x 300 mg/day TOBI®/PARI LC® PLUS.

Inclusion criteria
Inclusion criteria: 1. Signed by patient (or appropriate legal representative) the written informed consent including data protection agreement after the nature of the study has been fully explained prior to any screening procedure 2. Patient is a male or female and at least 4 years of age at the time of screening 3. Patient's diagnosis of cystic fibrosis (CF) was confirmed by one or more specific clinical features consistent with CF and elevated chloride concentration in the sweat is greater than 60 mEq/l (by quantitative pilocarpine iontophoresis test - QPIT) 4. Presence of disease associated CF transmembrane conductance regulator (CFTR) mutations in both alleles 5. Patient has adequate pulmonary function at screening defined as: 5.1. Forced expiratory volume in one second (FEV1) between at least 25% and less or equal to 85% of normal predicted values for age, sex and height based on Knudson criteria and peripheral artery haemoglobin oxygen saturation (SaO2) of at least 88% at rest measured by pulse oximetry on room air 6. Patient has a positive culture for PA at screening (Visit 1) 6.1. Patient should have PA isolated from sputum only if patient do not have a known history of positive PA culture within the last 2 months 7. Patient is clinically stable at screening (no change in FEV1 greater than 20% within one month prior to screening visit) 8. Patient is able to comply with all protocol requirements (e.g. able to produce sputum and perform pulmonary function tests) 9. Sexually active women of childbearing potential and sexually active men will use a highly effective method of contraception throughout the IMP treatment period 10. Females of childbearing potential have a negative serum pregnancy test (within 7 days before visit 2/randomisation)
Exclusion criteria

Administration of anti-pseudomonas aminoglycoside antibiotics are not allowed within 30 days before first administration of IMP. Macrolide are permitted, provided that they are taken as a maintenance therapy for at least 6 weeks before entering the trial.
