Pulmonary Infection Covid-19 | Drug: T3 solution for injection Drug: Placebo | Phase 2 |
It seems that thyroid hormone is critical in the response to body injury and is now considered as potential pharmaceutical intervention to limit acute tissue injury. TH (via its regulation of stress induced p38 MAPK activation) exerts antiapoptotic action and protects tissue from injury, with additional favorable effects on immune system and on viral load in infected tissue. This may be a novel and more effective treatment for critically ill viral infected patients.
ThyRepair is the first study which is underway and investigates the safety and efficacy of high dose T3 treatment in patients with acute myocardial infarction undergoing primary angioplasty. The preliminary reports show that this treatment is safe and the efficacy on tissue repair is promising. This therapeutic modality could also be tested in the acute setting of sepsis in which thyroid hormone is involved in the pathophysiology of multi-organ dysfunction. The safety and efficacy of T3 on heamodynamics in sepsis has been previously demonstrated in a small trial.
The present study is phase II, parallel, prospective, randomized, double-blind, placebo controlled trial which aims to investigate the potential effect of T3 intravenous use in the recovery of critically ill patients admitted in ICU due to COVID19 infection.

Experimental: T3 solution for injection
T3 Solution for injection 10 μg/ml, each vial contains 150μg of liothyronine in a total volume of 15ml. The dose administered will be 0.8g/kg i.v. bolus starting within 60min after respiratory support and will be followed by an infusion of 0.113g. kg-1.h-1 i.v. for 48 hours (therapeutic dose). After the first 48h, a maintenance dose will be administered corresponding to 50% of the therapeutic dose (0.057g. kg-1.h-1 i.v.). Drug administration will stop after successful weaning or end of followup (maximum 30 days).
|
Drug: T3 solution for injection
For example, for a patient of 77Kg of weight, a dose of 6ml (60 μg) will be administered as a bolus intravenously over 2-3 min within 60 min of respiratory support initiation. Then, the patient for the next 24 hours will receive 21ml of the product (total of 210 μg of T3) that will be diluted in NaCl 0.9% and administered with a pump at a steady flow rate of 10.4 ml/h for a total duration of 48 hours. From day 3 till successful weaning or end of follow-up, the patient will receive 50% of this dose, 10.5 ml of the product (total of 105 μg of T3) that will be diluted in NaCl 0.9% and administered with a pump at a steady flow rate of 5.2 ml/h. |
Placebo Comparator: Placebo
Composition identical apart from the active substance. Same dosage.

Drug: Placebo
Same as with T3 solution for injection. |
- Assessment of weaning from cardiorespiratory support [ Time Frame: 30 days ]The primary objective of the study is to determine whether the administration of intravenous triiodothyronine in ICU patients diagnosed with pulmonary infection due to COVID-19 facilitates weaning from cardiorespiratory support compared to placebo. Successful weaning is defined as no requirement for ventilatory support after extubation (mechanical support) or support from ECMO for 48 hours. The primary objective will be measured as percentage of patients successfully weaned after 30 days of follow-up.

- Assessment of hemodynamic status [ Time Frame: 30 days ]Hemodynamic status will be assessed by continuous blood pressure measurements (mean BP in mmHg)
- Assessment of hemodynamic status [ Time Frame: 30 days ]Hemodynamic status will be assessed by the number of participants with use of inotropic and vasoactive drugs
- Assessment of pulmonary function [ Time Frame: 30 days ]Pulmonary function will be assessed by arterial measurement of blood gases (arterial partial pressure of oxygen in mmHg)
