Descriptive Information
Brief Title  ICMJE Poractant Alfa - Curosurf and SARS-COV-19 ARDS (Covid-19)
Official Title  ICMJE Multicenter, Open-label, Randomised Trial to Assess the Efficacy and Tolerability of Poractant Alfa(Porcine Surfactant, Curosurf®) in Hospitalized Patients With SARS-COV-19 Acute Respiratory Distress Syndrome (ARDS)
Brief Summary The purpose of this Phase II -Proof of Concept study is to evaluate the efficacy and safety of poractant alfa (Curosurf®), administered by endotracheal (ET) instillation in adult hospitalized patients with SARS-COV-19 acute respiratory distress syndrome (ARDS)
Detailed Description

This is a multicentre, open-label, randomized phase II proof of concept study. The efficacy and safety of poractant alfa will be evaluated in terms of ventilatory free days during the 21 days after randomization, in adult patients with ARDS due to SARS-COV-19 infection.

Each patient randomized to the study treatment will receive three administrations of Curosurf ® with a 24 hours dosing interval.

The assessment collection will last until day 28 when the evaluation will occur at the ICU, or by phone call if the patient has been discharged before.

Seventy patients will be randomized in the study with a ratio 3:2 (i.e. 42 patients in the poractant alfa arm and 28 in the control arm).

The control arm population is treated as per Standard of Care (SoC).

This study will be conducted in UK, US and Italy.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
Seventy patients will be randomized in the study with a ratio 3:2 (i.e. 42 patients in the poractant alfa arm and 28 in the control arm).
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Acute Respiratory Distress Syndrome
Intervention  ICMJE Drug: CUROSURF® (poractant alfa)

Three administrations with a 24 hours dosing interval.

Each ET administration 1, 2, and 3 will consist of poractant alfa bolus:

30mg /kg (Lean Body Weight-LBW) = 0.375ml /kg LBW. Dilution with normal saline up to 2ml /kg LBW

Study Arms  ICMJE
  • No Intervention: Control cohort

    Approximately 28 patients will be included in this main control cohort.

    The above-mentioned control cohort population will continue receiving the SoC

  • Experimental: Poractant alfa treated cohort
    42 patients will be treated with CUROSURF® (poractant alfa).
    Intervention: Drug: CUROSURF® (poractant alfa)
