About this trial

This is an interventional treatment trial for Cystic Fibrosis focused on measuring subjects with cystic fibrosis and pseudomonas aeruginosa colonization in the upper airways

Eligibility Criteria

8 Years - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • subject has a confirmed diagnosis of cystic fibrosis
  • detection of P. aeruginosa in nasal lavage (culture) with chronic P.a. colonization of the lung (from day -28)
  • informed consent of the patients or parents
  • subject is older than 7 years
  • subject is able to comply with the inhalation procedures and nasal lavage procedures scheduled in the protocol
  • women of childbearing potential are only included into the study, if they are using an effective method of birth control during the protocol

Exclusion Criteria:

  • subject has a critical condition defined as: FEV1 < 30% and / or SaO2 < 93% without O2-substitution; need of O2-substitution
  • subject had an ENT surgery within 3 months prior to study
  • subject shows signs of nasal bleeding
  • subject has an ear drum perforation
  • subject had an acute rhinosinusitis or a pulmonary exacerbation at study entry with need of additional systemic antibiotic therapy against pseudomonas aerug.
  • subject is unlikely to comply with the procedures scheduled in the protocol
  • subject has a known allergic reaction to the medication
  • subject is pregnant or breastfeeding
  • subject participates in another clinical trial within 30 days prior to study entry or 30 days after end of the study.
  • systemic (oral or intravenous) antibiotic treatment against P.a. 14 days prior to the inclusion and during the study
  • if serum level of tobramycin is above 2 mg/l one hour after inhalation, subject has to withdraw the participation in the study.
  • progressed renal insufficiency
  • severe damage of the N. acusticus
  • dizziness (potential damage of. N. vestibularis)
