Confirmatory Phase II/III Study Assessing Efficacy, Immunogenicity and Safety of IC43 - Full Text View

Purpose

This is a confirmatory, randomized, placebo-controlled, multi-center, double-blinded phase II/III study. The study population consists of male or female ICU patients with a need for mechanical ventilation for more than 48 hours, aged between 18 and 80 years.

Arms	Assigned Interventions
Active Comparator: IC43 100 mcg IC43 100 mcg intramuscular injection, IC43 is a recombinant Pseudomonas aeruginosa fusion protein	Biological: IC43 100 mcg Other Name: Pseudomonas Aeruginosa

Detailed Description:

This is a confirmatory, randomized, placebo-controlled, multi-center, double-blinded phase II/III study. The study population consists of male or female ICU patients with a need for mechanical ventilation for more than 48 hours, aged between 18 and 80 years.

Eight-hundred patients will be enrolled at approximately 50 study centers. Informed consent (i.e., from the patient or from the patient's legally authorized representative) or waiver will be obtained according to regional requirements prior to any study related procedures. Patients will be randomized to receive either IC43 100 mcg or placebo and will receive the first vaccination on Day 0. The second vaccination will be applied on Day 7. In case ICU discharge occurs before Day 7, immunization will be done at the hospital ward.
