---|---|
Active Comparator: 5 day of infusion of gallium nitrate
Gallium nitrate will be infused continuously over 5 days at 200 mg/m2/day. Study drug will be administered via a peripheral IV catheter, a peripherally inserted central catheter (PICC) line, midline catheter, or a chronic indwelling vascular access device () using an ambulatory infusion pump infused over 24 hours for 5 sequential days.
|
Drug: Gallium nitrate
Study subjects will receive an infusion of either placebo or gallium nitrate.
Other Name: Ga, GaN3O9 |
Placebo Comparator: 5 day of infusion of normal saline
Placebo with be dispensed as 1,000 milliliters of 0.9% sodium chloride to match the reconstitution volume of the IV Ga
|
Drug: Normal Saline
Study subjects will receive an infusion of either placebo (normal saline) or gallium nitrate.
Other Name: Sodium Chloride, NS |
- Number of Participants With 5% or Greater Relative Change in FEV1 (Liters) From Baseline to Day 28 [ Time Frame: Baseline to Day 28 ]Difference between treatment groups in the proportion of subjects with 5% or greater relative change in FEV1 (liters) from baseline to Day 28.
- Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Day 1 to Day 56 ]Incidence is defined as the number and percentage of participants with at least one event over the 56 day follow-up period.
- Rate of Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Day 1 to Day 56 ]Rate is defined as the number of events per participant follow-up week.
- Relative Change in FEV1 (Liters) From Baseline to Day 56 [ Time Frame: Day 1 to Day 56 ]Difference between treatment groups in the relative change in FEV1 (liters) from Baseline to Day 56
- Absolute Change in P. Aeruginosa Sputum Density (log10 (CFU)) From Baseline to Day 56 [ Time Frame: Day 1 to Day 56 ]Difference between treatment groups in the absolute change in P. aeruginosa sputum density (log10 (CFU)) from Baseline to Day 56 based on quantitative cultures.
- Absolute Change in Respiratory Symptoms, as Measured by the CF Respiratory Symptoms Diary-Chronic Respiratory Infection Symptom Severity Score (CFRSD-CRISS), From Baseline to Day 56 [ Time Frame: Day 1 to Day 56 ]Difference between treatment groups in the absolute change in respiratory symptoms, as measured by the the CF Respiratory Symptoms Diary-Chronic Respiratory Infection Symptom Severity Score (CFRSD-CRISS), from Baseline to Day 56. The Cystic Fibrosis Respiratory Symptoms Daily Diary asks a participant to state the extent of their 8 respiratory symptoms : difficulty breathing, feverishness, tiredness, chills or sweats, coughing, coughing up mucus, tightness in the chest and wheezing. Each respiratory symptom is assigned a score from 0-4 based on the response, with zero corresponding to the absence of the symptom and four corresponding to symptom being present 'a great deal' or 'extremely'. A summed score (range from 0-24) is calculated for each participant and converted to a final score with a range of 0 to 100, where the lowest scores indicate improvement of symptoms.
