Primary Outcome Measures:
  • Change from baseline in Clinical Pulmonary Infection Score (CPIS) during the planned 10-day treatment period. [ Time Frame: 10 day treatment period. ] [ Designated as safety issue: No ]
    Daily CPIS will be determined by one blinded, central reviewer in order to minimize inter-observer variability.

Secondary Outcome Measures:
  • Composite endpoint of mortality and ventilator-free days [ Time Frame: Day 1- Day 28 ] [ Designated as safety issue: No ]
    The hierarchical composite endpoint of mortality and ventilator-free days.

  • Number of days free of mechanical ventilation from Day 1 through Day 28 [ Time Frame: Day 1 - Day 28 ] [ Designated as safety issue: No ]
  • Number of ICU days from Day 1 through Day 28 [ Time Frame: Day 1 - Day 28 ] [ Designated as safety issue: No ]
  • Microbiological response rates in patients positive for multi-drug resistant Gram-negative bacteria [ Time Frame: Day 14 ] [ Designated as safety issue: No ]
    Microbiological response rates at Day 14 in patients whose pre-study treatment bronchoalveolar lavage (BAL) was positive for multi-drug resistant Gram-negative bacteria

  • Mortality from Day 1 through Day 28 [ Time Frame: Day 1 - Day 28 ] [ Designated as safety issue: No ]
  • Clinical relapse rate [ Time Frame: Day 11 - Day 28 ] [ Designated as safety issue: No ]
    Clinical relapse rates (defined as a new episode of pneumonia requiring reinstitution of IV antibiotics) from Day 11 through Day 28

Detailed Description:

The primary purpose of this study is to demonstrate the safety and efficacy of the amikacin fosfomycin inhalation system (AFIS). AFIS consists of amikacin solution and fosfomycin solution, delivered by aerosol to the lungs via the PARI Investigational eFlow Inline System (eFlow Inline System). All patients will receive a standardized course of intravenous (IV) antibiotics for a minimum of 7 days. Patients will be randomized to receive 10 days of treatment with either AFIS or placebo, in addition to the IV therapy. The primary efficacy endpoint is defined as the change from baseline in the Clinical Pulmonary Infection Score (CPIS) during the randomized course of study drug.


Ages Eligible for Study:   18 Years to 80 Years

Inclusion Criteria:

  • Males and non-pregnant, non-lactating females, ≥ 18 years and ≤ 80 years of age
  • Intubated and mechanically ventilated
  • Diagnosis of pneumonia, defined as presence of a new or progressive infiltrate(s) on chest radiograph (within 24 hours of the start of IV antibiotics for this episode of pneumonia), as determined by the treating physician
  • Signs of infection (within 24 hours prior to screening):

    1. Fever (> 38ºC or > 100.4ºF); or
    2. Leukopenia (< 4,000 WBC/mm3) or leukocytosis (≥ 12,000 WBC/mm3)
  • Impaired oxygenation (within 24 hours prior to screening):

    a. PaO2/FiO2 ≤ 300 mmHg

  • Acute Physiology and Chronic Health Evaluation (APACHE) II score > 10 on the day of ICU admission
  • Presence, or high suspicion, of Gram-negative organism(s) by either Gram stain or culture of respiratory secretions from a sample obtained within the previous 7 days (enrollment can occur before culture results are available)

Exclusion Criteria:

  • History of hypersensitivity to amikacin, other aminoglycosides, fosfomycin, imipenem, meropenem, or colistin
  • Received systemic antibiotic therapy for this episode of Gram-negative pneumonia for greater than 72 hours at the time of randomization
  • PaO2/FiO2 ≤ 100 mmHg and diffuse infiltrates on Chest X-ray
  • Refractory septic shock (severe sepsis plus unstable hypotension, in spite of adequate fluid resuscitation and vasopressors)
  • Any of the following conditions that interfere with the assessment or interpretation of the diagnosis or response to therapy:

    1. chest trauma with ongoing loss of stability of the thoracic cage following a fracture of the sternum, ribs, or both;
    2. increased amounts of fluid in the lung cavities requiring chest tube drainage;
    3. lung cancer within the last 2 years;
    4. lung abscess(s);
    5. anatomical bronchial obstruction;
    6. suspected atypical pneumonia;
    7. chemical pneumonitis (e.g., inhalation injury);
    8. cystic fibrosis
