Inclusion criteria
- {"criterion_text":"- Phase 1: Participants are eligible to participate in the dose-escalation part of the trial if they are healthy, between 18 and 55 years of age, and have a Body Mass Index (BMI) of ≥ 18.5 and ≤ 29.9 kg/m2"}
- {"criterion_text":"- Phase 2a: Adult CF/PCD/NCFB patients with chronic airway infection are eligible to participate in the PoC part of the trial if their underlying CF/PCD/NCFB disease is stable and they are able to spontaneously expectorate >1 g sputum with a bacterial density of at least 5 log10 colony-forming units (CFU) per g"}
Exclusion criteria
- {"criterion_text":"- Phase 1: Participants are not eligible to participate in the dose-escalation part of the trial if they have recently participated in another clinical trial or have donated blood; are pregnant or lactating; have a medical condition or a history of drug hypersensitivity; are using concomitant medication."}
- {"criterion_text":"- Phase 2a: CF/PCD/NCFB patients are not eligible to participate in the PoC part of the trial if their forced expiratory volume (FEV1) is below 30% of predicted or their oxygen saturation is below 90% determined by pulse oximetry; if they have recently participated in another clinical trial or have donated blood; are pregnant or lactating; have a medical condition other than their underlying CF/PCD/NCFB disease which in the opinion of the investigator precludes participation in the trial; have a history of drug hypersensitivity."}
