This will be a multicenter, randomized, controlled, double-blind, Phase ii clinical trial.
eighty pancreatic insufficient (Pi) subjects with CF, [GreaterThanorequalTo] 10 years of age will be enrolled to
participate in this study.
each subject will come to clinic for up to 5 study visits (see Figure 1). Screening: Visit 1
(Screening, Day -28 up to -60), Visit 2 (Baseline, Day 0), Visit 3 (Week 4, Day 28) and Visit 4
(Week 16, Day 112). Following the screening visit, there will be a four to eight-week open-label
screening/run-in period in which subjects will be instructed to discontinue their current CF
multivitamin and any additional vitamin supplementation and take a control multivitamin
without antioxidant enrichment (containing standard amounts of vitamins a, B, D, e, K).
at Visit 2 (Baseline), subjects will be randomized to receive either aquaDeKs-2 or to
continue on the control multivitamin once daily for an additional 16 weeks. Safety and
tolerability will be monitored. a fasting blood draw for vitamin and nutrient levels and
systemic markers of inflammation and oxidative stress, anthropometric measures, and
pulmonary function will be obtained at Visits 2 (Baseline), 3 and 4. induced sputum and
urine specimens will be collected at Visits 2 and 4 to measure markers of airway
inflammation and oxidative stress. Subjects will be contacted by phone 2 weeks after
Visit 4 to assess safety. if a subject had a clinically significant abnormal lab result or ongoing
treatment-related ae at Visit 4, the subject will be asked to return for a follow-up
visit two weeks after Visit 4 instead of the call.

Subjects will be on study for up to 26 weeks:
Screening/Run-in: 4-8 weeks
Treatment: 16 weeks
Follow-up: 2 weeks
