• Males and females 5 years of age and above (being able to gargle)

• CF patients having a FEV1 value between 50% and 130% of predicted value (according to Knudson formula)

• CF patients who have had one to several sputum or throat cough swabs or endolaryngeal suction cultures positive for PA within the last three years and for whom PA has been successfully eradicated.

• Sputum / throat cough swab/ endolaryngeal suction culture negative for PA and other gram-negative bacteria on study entry.

• Patients and/ or their legal representative who are willing and able to give informed consent/ assent to participate in the study after thorough information

• Subjects of child bearing potential and who are sexually active must meet the contraception requirements (i.e. oral or injectable contraceptives, intrauterine devices, double-barrier method, contraceptive patch, male partner sterilization or condoms).

Exclusion Criteria:

• Microbiologic or serologic evidence of chronic infection with PA. Definition of chronic PA infection: Three cultures (sputum or throat cough swabs or endolaryngeal suction) have been positive for PA for 6 consecutive months (at least 3 cultures have to be taken) or more, .

• Patients, who have positive sputum culture or throat cough swab or endolaryngeal suction culture for gram-negative bacteria, such as PA, S. maltophilia, B. cepacia, A. xylosoxidans (eradication before entry in study is possible), Patients, who have positive sputum culture or throat cough swab or endolaryngeal suction culture for atypical Mycobacteria and / or Aspergillus fumigates, associated with clinical symptoms that may necessitate specific treatment.

• History of allergy/hypersensitivity to hens' egg proteins (including medication allergy) that is deemed relevant to the trial by the investigator. "Relevance" in this context refers to any increased risk of hypersensitivity reaction to trial medication.

• Patient with a known relevant substance abuse, including alcohol or drug abuse.

• Start of a new concomitant or chronic medication for CF within 4 weeks before inclusion.

• Clinically relevant diseases or medical conditions other than CF or CF-related conditions that, in the opinion of the investigator, would compromise the safety of the patient or the quality of the data. This includes, but is not limited to, significant hematological, hepatic, renal, cardiovascular, and neurological diseases (diabetic patients may participate if their disease is under good control prior to inclusion).

• Participation in another study with an investigational drug within one month or 6 half-lives (whichever is greater) preceding the inclusion.

• The patient is an employee of the investigator or the institution with direct involvement in the trial or other trials under the direction of the investigator or their members.
