Cystic Fibrosis | Device: RELiZORB (immobilized lipase) cartridge Other: Impact Peptide 1.5 | Not Applicable |
Study Entry (Day -14): Baseline blood samples collected for plasma and erythrocyte concentrations of docosahexaenoic acid (DHA) and eicosapentaenoic (EPA). Baseline characteristics collected included BMI and cystic fibrosis related diabetes.
Observation Period (Day -14 to Day -8): Subjects followed their usual enteral nutrition regimen with pancreatic enzyme replacement therapy (PERT).
Run-in Period (Day -7 to Day -1): Subjects used Peptamen 1.5 enteral formula at their normal volume of administration from 500 mL to 1,000 mL per feeding with usual PERT regimen.
Treatment Period (Day 0 to Day 90): Subjects used Impact Peptide 1.5 up to a maximum volume of 1,000 mL per feeding with RELiZORB for the 90 day treatment period. Blood screening measurements were repeated at start of treatment period (Day 0), Day 30, Day 60 and Day 90. PERT use with enteral feedings was prohibited. Safety and tolerability were assessed with GI symptom diaries and systematic assessments of adverse events and unanticipated adverse device effects.

- Change From Baseline of Erythrocyte Omega-3 Index % (DHA+EPA) [ Time Frame: Day 0 to Day 90 ]Change from baseline Day 0 to Day 90 of erythrocyte tissue composition % of the omega-3 index
- Unanticipated Adverse Device Effects (UADE) [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days with additional 30 days of follow up. ]A UADE is analogous to a serious adverse event (SAE), defined as an AE, occurring at any exposure to the therapeutic agent, that results in any of the following outcomes: death, life-threatening AE, inpatient hospitalization or prolonged existing hospitalization, a persistent or significant disability or incapacity or a congenital anomaly/birth defect.
- Changes in Plasma Concentration Total DHA+EPA [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days ]Changes in plasma concentration total DHA+EPA from baseline (Day 0 to Day 90).
- Erythrocyte Composition (%) of DHA [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days ]Changes over time in erythrocyte composition (%) for total DHA in ITT population (n=39)
- Erythrocyte Composition (%) of EPA [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days ]Changes over time in erythrocyte composition (%) for EPA in ITT population
- Erythrocyte Composition (%) Ratio of n6/n3 Fatty Acids [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days ]Change from baseline to Day 90 in n6/n3 ratio in erythrocytes
- Plasma Composition (%) Ratio of n6/n3 Fatty Acids. [ Time Frame: RELiZORB Treatment Period (Day 0-Day 90): 90 days ]Change over time in n6/n3 ratio in plasma in the ITT population
- GI Symptoms [ Time Frame: Observation, Baseline and RELiZORB Treatment periods (Day -14 to Day 90): 104 days with additional 30 days of follow up. ]GI symptoms recorded in GI diaries by subject and/or caregiver.
