Trial of Aeroquin Versus Tobramycin Inhalation Solution (TIS) in Cystic Fibrosis (CF) Patients

This study will assess the comparative safety of MP-376 (Aeroquin) and Tobramycin Inhalation solution (TIS) \[TOBI® Novartis Pharmaceuticals\] over three consecutive cycles of 28-days treatment followed by 28-days off in stable CF patients with chronic P. aeruginosa lung infection. Efficacy data for MP-376 and TIS at the end of the first 28-day treatment period will also be compared, as well as explored over multiple treatment cycles. Study patients participating in Mpex 209 will be given the option to participate in a six-month open label extension phase of the Mpex 209 protocol. The open label extension will allow enrolled patients to receive three additional courses of MP-376 (levofloxacin inhalation solution, Aeroquin™). Study with completed results acquired from Horizon in 2024.
