Key inclusion criteria
Key

1. Phase 1: Healthy males or females aged 18 to 65 years at the time of informed consent.

Phase 1b: Males or females aged 18 to 65 years with confirmed diagnosis of CF documented in subject's medical record
2. Body weight between 40-100Kg and body mass index between 16-35 kg/m2
