The purpose of this research study is to test the pharmacokinetics, safety, and tolerability of an intravenous infusion of a drug called Ganite (gallium nitrate) in patients with cystic fibrosis. We want to see this drug is safe and tolerable and to see if high levels of the drug are found in the sputum.
This is a two center pharmacokinetic and safety dosing study of IV gallium nitrate (Ganite®) in cystic fibrosis (CF) patients. Eighteen subjects are planned. Each subject will be administered a single 5-day infusion of study medication (one of 2 doses). No placebo is used. Each subject will receive 5 days of continuous infusion of the experimental treatment. There will be two dosing cohorts (cohort 1: 100 mg/m2/day and cohort 2: 200 mg/m2/day). Cohort 2 will begin enrollment only after Data Safety Monitoring Committee (DSMC) safety review and approval of cohort 1 data. Study visits occur at baseline (day 1), day 3 (visit 2), day 6 (visit 3), day 8 (visit 4), day 14 (visit 5) and day 28 (visit 6).
Screening data will be reviewed to determine subject eligibility. Subjects who meet all inclusion criteria and none of the exclusion criteria will be entered into the study.
The following treatment regimens will be used:
• Experimental treatment continuous infusion of gallium nitrate at the following doses cohort 1: 100 mg/m2/day and cohort 2: 200 mg/m2/day All subjects who receive at least one dose of study medication will be considered evaluable for safety and efficacy analyses. Incidence of adverse events will be monitored during the trial.
Primary endpoints will be assessment of pharmacokinetic and safety/tolerability data.
Secondary efficacy assessments will be based on changes in lung function and sputum P. aeruginosa density in sputum.
Total duration of subject participation will be five weeks. Total duration of the study is expected to be 20 months.

There are many challenges to providing end-of-life care (EOLC) to people with cystic fibrosis (CF).
The purpose of this study was to evaluate hearing impairment in pediatric patients with cystic fibrosis (CF).
Staphylococcus aureus (S. aureus) may be related to more rapid progression of cystic fibrosis (CF) lung disease.
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.
Stable gallium atoms that have the same atomic number as the element gallium, but differ in atomic weight. Ga-71 is a stable gallium isotope.
