PREV-HAP
Brief Summary:
PREV-HAP study is part of a larger project entitled 'Host-targeted Approaches for the Prevention and the treatment of Hospital-Acquired Pneumonia' (HAP2), funded by the European Union's H2020 research and innovation programme under grant agreement N°847782. HAP2 aims to develop stratified host-directed drugs and biomarkers to enhance the prevention and the treatment of HAP and develop precision medicine in infectious diseases. Its ambition is to revolutionize the management of HAP: capitalising on the novel concept of critical-illness related immunosuppression altering the host-pathogens interactions, the aim is to propose a complete reappraisal of the physiopathology of HAP based on the concept of respiratory dysbiosis.
The main hypothesis of the PREV-HAP study is that human recombinant Interferon gamma 1b (rHuIFN-γ, Imukin) treatment can restore immunity in critically ill patients and prevent Hospital-Acquired Pneumonia.
The hypothesesis is that the in vivo investigations of the host-pathogens interactions can be used for the stratification of patients into high/low risk and responders/non-responders to host-targeted prevention of hospital-acquired infections.
The involvement of a state of critical-illness related immunosuppression in the susceptibility to hospital-acquired pneumonia is widely accepted, and an emerging trend is that the development of drugs for the treatment of this acquired immunosuppression will prevent infection and enhance outcomes of hospitalized patients.
It has been demonstrated that the productions of IFN-γ by immune cells are decreased in critically ill patients, and that these defects are associated with the susceptibility to HAP. rHuIFN-γ has neither been tested nor is recommended as adjunctive treatment of patients with HAP. Based on these specific factors identified in the host response, it is proposed in this study to use rHuIFN-γ as novel preventive approach for HAP.

Detailed Description:
200 adult patients hospitalized in intensive care units, under mechanical ventilation in three European countries will be included in the trial, and will be randomized in 2 arms :
Arm 1 (rHu-IFNγ):
• Recombinant Interferon gamma 1b (IMUKIN®, from Clinigen®): 100 µg/0,5ml subcutaneous injections from day 1 to day 9 (5 injections, i.e. 1 injection of 100 µg every 48h),
Arm 2 (Placebo):
• Recombinant Interferon gamma 1b placebo: 5 subcutaneous injections from day 1 to day 9 (i.e. 1 injection of 0,5ml every 48h).
