Summary
This trial will test 4 doses of a drug (RSP-1502) to find the most effective and safe dose. Subjects will receive the drug or an active control & be monitored for safety & efficacy.
Who is the study for?
Adults over 18 with cystic fibrosis and chronic lung infection caused by P. aeruginosa, who haven't had significant respiratory symptoms or changes in their CF treatments for the past month. They must be able to avoid other inhaled antibiotics during the study and have a stable organ function as determined by tests. Women of childbearing age should use contraception, men should either be infertile or agree to use condoms.
What is being tested?
The trial is testing RSP-1502, an aerosolized drug combined with different doses of CaEDTA compared to Tobramycin inhalation solution. Participants will inhale their assigned treatment twice daily for two weeks while being monitored for safety and effectiveness. The best dose will be chosen based on tolerance levels observed across groups.
What are the potential side effects?
Potential side effects may include allergic reactions to components of RSP-1502, issues related to nephrotoxicity (kidney damage), neurotoxicity (nerve damage), or ototoxicity (hearing loss) due to medication ingredients similar to those found in some participants' excluded medications.
