COVID-19
Conditions
Brief summary
The aim of this study is to evaluate the efficacy and safety of MTX-loaded nanoparticles in three different doses to treat severe COVID-19 patients.
Detailed description
Patients with acute lung injury caused by COVID-19 disease are experiencing an inflammatory reaction that can be harmful and worsen the severity of the clinical condition. Thus, the use of MTX-loaded nanoparticules in patients with acute lung injury secondary to COVID-19 aims to decrease the exacerbated inflammatory reaction leading to a decrease in cell damage caused by this inflammatory process in patients. The study will be divided in 3 phases: Phase A (n=4): IV administration of 20 mg of MTX-loaded nanoparticles. Four doses of Investigational Product (IP) will be administered, once per week. If patients show clinical improvement after 2nd or 3rd administration, the next phase will start. Phase B (n=12): IV administration of 30 mg of MTX-loaded nanoparticles. Four doses of Investigational Product (IP) will be administered, once per week. If patients show clinical improvement after 2nd or 3rd administration, the next phase will start. Fase C (n=26): IV administration of 40 mg of MTX-loaded nanoparticules. Four doses of Investigational Product (IP) will be administered, once per week.
Interventions
Phase A: Subjects will be dosed 20 mg of MTX IV, once per week (total of 4 doses).
