In this study effectiveness and safety of a new drug FP-1201-lyo (recombinant human interferon beta-1a) is compared to placebo. Investigation is conducted with patients who have acute respiratory distress syndrome (ARDS). The new drug is expected to reduce the time which a patient need to be on the ventilator and improve patient's chances of survival. Currently there are no approved drugs for treating moderate or severe ARDS patients.
This is a Phase III clinical study to investigate the efficacy and safety of FP-1201-lyo (recombinant human interferon \[IFN\] beta-1a) compared to placebo in patients diagnosed with moderate or severe acute respiratory distress syndrome (ARDS). Primary objective is to demonstrate the efficacy of FP-1201-lyo in improving the clinical course and outcome based on survival and need for mechanical ventilation. Currently there are no approved drugs for treating moderate or severe ARDS patients. FP-1201-lyo is a lyophilised powder form of recombinant human IFN beta-1a reconstituted in water for injection and is administered intravenously. Recombinant human IFN beta-1a is an approved treatment for patients for other indication and its safety profile in such patients is well characterised.

Composite Endpoint (VFDsurv; All-cause Mortality and Number of Days Free of Mechanical Ventilation) at Day 28
VFDsurv is a composite measure of all-cause mortality and the number of days free of mechanical ventilation (VFDsurv) within 28 days among survivors. Ventilator-free days (VFDs) correspond to those days when unassisted breathing (UAB) was possible for a complete calendar day. UAB was defined as: spontaneously breathing with face mask, nasal prong oxygen or room air, T-piece breathing, tracheostomy mask breathing, CPAP less than or equal to 5 cmH2O without pressure support or intermittent mandatory ventilation assistance, use of CPAP or BIPAP solely for sleep apnoea management. A patient was reported as ventilator-free after 2 consecutive calendar days of unassisted breathing (a VFD value of 0 is assigned to patients who die without initiating UAB or who require more than 28 days of mechanical ventilation. All patients who die before Day28 are assigned a VFDsurv value of -1).
Time frame: Day 28
Efficacy Endpoint: All-cause Mortality
Fatalities, mortality all-causes from randomisation up to Day 28
Time frame: At Day 28
Efficacy Endpoint: Mortality in ICU
All-cause mortality for subjects who died in Intensive Care Units up to Day 28.
Time frame: Up to Day 28
Efficacy Endpoint: Mortality in Hospital
This is the number of subjects who died in hospital (i.e. outside of Intensive Care Units) up to Day 28.
Time frame: Up to Day 28
Other Secondary Efficacy Endpoints: Days Free of Organ Failure
The total number of days free of organ failure by Sequential Organ Failure Assessment (SOFA) methodology. Overall, the median number of days free of organ failure was 0 days in both the treatment groups.

Time frame: Day 28 or last day in intensive care unit [ICU] if patient has left the ICU earlier than Day 28
Other Secondary Efficacy Endpoints: Days Free of Renal Support
Days without renal support (any renal support was documented). Overall, the median number of days free of renal support was 28 days in the active group and 27 days in the placebo group.
Time frame: Day 28
Other Secondary Efficacy Endpoints: Days Free of Vasoactive Support
Days without vasoactive support. The vasoactive support included catecholamine and non-catecholamine vasopressors, inotropes and vasodilating agents. Overall, the median number of days free of vasoactive support was 20 days in the active group and 21 days in the placebo group.
Time frame: Day 28
Other Secondary Efficacy Endpoint: Days Free of Mechanical Ventilation
The total number of days free of mechanical ventilation has been derived from the Patient Status report recorded on each day during the 28-day period. Patients who died during this period have been assigned a value of zero. This variable differs from the calculated "Ventilation Free Days (VFD) endpoint, which contribute to the VDFsurv primary efficacy endpoint as it require additional conditions of unassisted breathing (UAB) to be met.
Time frame: Day 28
Other Secondary Efficacy Endpoints: Number of ICU-free Days
Number of Intensive Care Unit free days up to Day 28, i.e. the patient is no longer receiving care in ICU. Patients who die during this period have been assigned a value of zero for the number of ICU care free days.
Time frame: Day 28
Other Secondary Efficacy Endpoints: Number of Days in Hospital
Hospitalisation days (including the stay at Intensive Care Units). Patients who died during this period have been assigned a value of 28 for the number of days in ICU or in hospital.
Time frame: Day 28
Evaluation of Safety: Adverse Events and Deaths
Adverse events (AE) up to Day 28. Per protocol, AEs occurring after Day 28 if the investigator considered a causal relationship with the study drug as well as all deaths up to Day 360 were reported. Treatment-emergent AEs (TEAEs) were defined as AEs that begins or worsens in intensity after at least one dose of study drug has been administered. Serious AEs (SAEs) were defined as any untoward medical occurrence that at any dose resulted in death; was life-threatening (immediate risk of death); required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was an important medical event.
Time frame: AEs up to Day 28, only related after Day 28 and deaths up to Day 360
Efficacy Endpoint: Presence of Neutralising Antibodies to IFN Beta-1a
The immunological response to FP-1201-lyo was assessed by monitoring presence of anti-drug binding antibodies (BAbs) and neutralising antibodies (NAbs) to IFN beta-1a on pre-dose Day 1 and at Day 28, the last day in ICU or early termination (if earlier). The BAbs were determined first, and if present, the NAbs were also determined. Presence of BAbs and NAbs were summarised categorically, using positive/negative classification.
Time frame: Baseline and Day 28 (or last day in intensive care unit [ICU] or at withdrawal, if earlier)
Efficacy Endpoint: Evaluation of Pharmacodynamic (PD) Using Myxovirus Resistance Protein A (MxA) Biomarker
Evaluation of MxA biomarker change from baseline to D14 between treatments arms over time.
Time frame: From baseline to Day 14
Long-term Efficacy Endpoint: Change in Quality of Life From Baseline to Day 180
Quality of Life was assessed through EQ-5D-3L (EuroQol 5-Dimensions 3-Levels questionnaire). An EQ Visual Analogue Scale (VAS) total score (ranging from 0-100) was measured (0= Worst imaginable health state, 100= Best imaginable health state). The EQ-5D-3L VAS scores are numerically summarised as change from pre-dose (Day 1) to long term follow-up (Day 180 visit).
Time frame: Change from baseline to Day 180
Long-term Efficacy Endpoints Relating to Respiratory Functioning (FEV1)
Measuring FEV1 (forced expiratory volume in 1 second) assessed pulmonary function (airway obstruction, bronchoconstriction or bronchodilation). FEV1 is the volume exhaled during the first second of a forced expiratory manoeuvre, starting from the level of total lung capacity.
Time frame: Day 180
Long-term Efficacy Endpoints Relating to Neurological Functioning (6MWT)
The 6-minute walk test (6MWT) measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes. According to the ERS/ATS technical standard to which the 6MWT was done, the walk test is done twice and the best result is used. It is an evaluation of the global and integrated responses of all systems involved during exercise, including the pulmonary and cardiovascular systems, systemic circulation, peripheral circulation, blood and neuromuscular units and muscle metabolism. The self-paced 6MWT assesses the sub- maximal level of functional capacity and will better reflect the functional exercise level for daily activities. ANOVA parameters estimates (LS Means and 90 % conf.interval) for the overall treatment difference was analysed.
Time frame: Day 180
