Inclusion Criteria
- Screening FEV1 between 40% and 100% predicted value for age, gender and height, in patients capable of properly performing the test; - History of pulmonary exacerbation, defined as at least one (1) pulmonary exacerbation in the year prior to Screening which resulted in documented intravenous or Oral antibiotics; - Patients are eligible independently of their history of pulmonary Pseudomonas aeruginosa (PsA) infection and their PsA status at screening; - If taking Kalydeco® (ivacaftor), Orkambi® (ivacaftor/lumacaftor), Symdeko® (ivacaftor/tezacaftor) or other commercially available CFTR modulator products, patients must be taking it for a minimum of 3 months prior to screening if naïve to CFTR modulators and 1 month if switched from another CFTR modulator product and deemed to tolerate it; - No change in CF and allowed systemic chronic therapy for a minimum of 5 weeks prior to randomization, of which 2 weeks minimum are prior to screening; - Female patients of child bearing potential should be on highly effective contraceptive methods during the study; - Male patients with spouse or partner of child bearing potential, or pregnant, are eligible if they use an appropriate method of contraception.
Exclusion Criteria

Detailed Description
An International Phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of LAU-7b administered once-daily for 6 months for the treatment of CF. All patients will remain on their CF standard-of-care treatments over the trial duration. The goal for the treatment with LAU-7b in CF is to preserve lung function by reducing the persistent inflammation in the lung and to improve its capacity to defend against resistant bacteria such as Pseudomonas aeruginosa. The treatment regimen will consist of 6 consecutive "dosing cycles" of 21 days each, spaced by study drug-free periods of 7 days. A total of 136 eligible adult patients with CF will be randomized to receive 300 mg LAU-7b or placebo in a 1:1 ratio. The participation in the study will last about 7 months.
