Brief Summary:
It is hypothesized that instillation of (T3) into the airspace will increase alveolar fluid clearance in patients with ARDS, resulting in reduced extravascular lung water (EVLW).

Condition or disease Intervention/treatment Phase
ARDS, Human Lung, Wet Thyroid Pulmonary Edema Lung Inflammation Drug: Liothyronine Sodium (T3) (modified formulation) Phase 1 Phase 2

Detailed Description:

Randomized, unblinded, intervention versus non-intervention trial

Purpose: To determine the safety and tolerability of T3 delivery into the lungs of ARDS patients, and to measure the effect of T3 on EVLW index in ARDS patients.

Liothyronine Sodium (T3), 5-10-25-50µg will be instilled via catheter through ETT into the airways in a total volume of 10 ml (T3+0.9% sodium chloride) over 4 days (96 hours) with progressive dosing.

68 participants [50 treatment + 18 controls] will be investigated over 18 months or until target enrollment is achieved. No research intervention will occur with control subjects. Control subjects will receive standard of care.

Arm Intervention/treatment
Experimental: Active treatment
Liothyronine Sodium (T3), 5-10-25-50µg instilled directly into the airways in a total volume of 10 ml (T3+0.9% sodium chloride). Progressive dosing every 24 hours for total 96 hours.
 Drug: Liothyronine Sodium (T3) (modified formulation)
Liothyronine Sodium (T3), 5-10-25-50µg instilled directly into the airways in a total volume of 10 ml (T3+0.9% sodium chloride). Progressive dosing every 24 hours for total 96 hours.
No Intervention: Control arm

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Extravascular Lung Water Index (EVLWI) [ Time Frame: baseline, 1 hour post T3 installation ]
    EVLWI is calculated as ml of extravascular lung water fluid reported by VolumeView system (Edwards Lifesciences) divided by patient's body weight in kg. EVLWI will be measured at baseline and 1 hour post T3 installation to calculate change in EVLWI. Lower EVLWI values indicate greater treatment efficacy.

  2. Change in Extravascular Lung Water Index (EVLWI) [ Time Frame: baseline, 12 hours post T3 installation ]
    EVLWI is calculated as ml of extravascular lung water fluid reported by VolumeView system (Edwards Lifesciences) divided by patient's body weight in kg. EVLWI will be measured at baseline and 12 hours post T3 installation to calculate change in EVLWI. Lower EVLWI values indicate greater treatment efficacy.

  3. Change in Extravascular Lung Water Index (EVLWI) [ Time Frame: baseline, 24 hours post T3 installation ]
    EVLWI is calculated as ml of extravascular lung water fluid reported by VolumeView system (Edwards Lifesciences) divided by patient's body weight in kg. EVLWI will be measured at baseline and 24 hours post T3 installation to calculate change in EVLWI. Lower EVLWI values indicate greater treatment efficacy.


Secondary Outcome Measures :
  1. Change in Arterial Oxygenation [ Time Frame: On clinically indicated ABGs (about 1 hour after admission), then 24 hours post T3 installation ]
    Arterial partial pressure of oxygen will be sampled by arterial catheter (reported as mmHg) upon admission and then 24 hours after the first dose of T3 to calculate change in arterial partial pressure of oxygen. Increased arterial partial pressure of oxygen indicates greater treatment efficacy.
