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

Patients with cystic fibrosis (CF) suffer from chronic infections of the lower respiratory tract that can be caused by one or multiple bacteria, including Pseudomonas aeruginosa, which has been particularly problematic to eradicate and been implicated as the major cause of morbidity and mortality in CF patients. Aerosol delivery of antibiotics directly to the lung increases the local concentrations of antibiotic at the site of infection resulting in improved antimicrobial effects compared to systemic administration. Bacterial resistance to current aerosol antibiotic treatments indicate a need for improved therapies to treat CF patients with pulmonary infections caused by multi-drug resistant Pseudomonas aeruginosa and other bacteria. High concentrations of MP-376 delivered directly to the lung are projected to have antimicrobial effects on even the most resistant organisms.

Primary Outcome Measures:
  • Safety [ Time Frame: 168 and 336 days ]

    Assessment of adverse events and safety from Baseline through Final Visit

    Extension portion of Study: Descriptive statistics for all patients receiving at least one dose of MP-376 in the extension phase of the study will be summarized for the safety, microbiology, and disease-related endpoints. No formal hypothesis tests are planned.

  • Efficacy [ Time Frame: 28 Days ]
    Percent change in percent predicted FEV1 from Baseline to Day 28

Secondary Outcome Measures:
  • Changes in respiratory and other domains of CFQ-R from Baseline to Day 28 [ Time Frame: 28 days ]
  • Evaluate changes in FEV1 and FVC from Baseline to Day 28 [ Time Frame: 28 days ]
  • Changes in bacterial load and susceptability patterns of isolated organisms from Baseline to Day 28 [ Time Frame: 28 days ]

Enrollment: 267

Arms Assigned Interventions
Experimental: Aeroquin
Aeroquin, Inhaled Levofloxacin (MP-376)
Drug: MP-376 (Levofloxacin Solution for Inhalation)
MP-376 (Aeroquin, Levofloxacin solution for Inhalation) 240 mg administered BID for 28-days treatment followed by 28 days off treatment
Other Name: (Aeroquin, Levofloxacin solution for Inhalation)
Active Comparator: TIS
Tobramycin Inhalation solution (TIS) [TOBI® Novartis Pharmaceuticals]
Drug: TIS (Tobramycin Inhalation Solution)
Tobramycin Inhalation Solution administered BID over 3 consecutive cycles of 28-days treatment followed by 28 days off treatment
Other Name: TOBI

Detailed Description:

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™).
