Official Title
Two Phases Clinical Trial to Evaluate Safety and Efficacy of Methotrexate Associated to LDL Like Nanoparticles (LDE-MTX) in the Treatment of Patients With Mild Coronavirus-19 (COVID-19) Disease.
Brief Summary

The investigators propose a prospective, randomized, double-blind, placebo-controlled study, conducted in two phases. The purpose of the study is to evaluate the safety and efficacy of methotrexate in a cholesterol-rich non-protein nanoparticle (MTX -LDE) in adults diagnosed with mild Coronavirus-19(COVID-19) disease. A total of 100 patients will be randomized to receive MTX-LDE or placebo each 7 days, up to 3 times, during in hospital treatment.

Detailed Description

The objective of the study is to evaluate the safety and efficacy of (MTX -LDE) in patients
with mild Coronavirus-19 (COVID-19) disease.

In phase 1, firstly 3 patients with moderate COVID-19 disease will receive MTX-LDE IV 15mg
each 7 days, up to 3 times, during hospitalization. After that, 9 patients with moderate
COVID-19 disease will receive MTX-LDE IV 30mg each 7 days, up to 3 times, during
hospitalization. Follow-up assessments will occur daily following randomization during in
hospital treatment and 2 weeks after discharge for evaluation of the occurrence of adverse
events.The purpose of this phase will be evaluate safety and pharmacokinetics.

If no objection by data and safety monitoring board (DSMB), will be authorized to start the
second phase.

In phase 2, 88 patients with moderate COVID-19 disease will be randomized to receive MTX-LDE
IV 30mg or placebo-LDE IV each 7 days, up to 3 times, during hospitalization. Follow-up
assessments will occur daily following randomization during in hospital treatment and 2 weeks
after discharge for evaluation of the occurrence of any trial endpoints or other adverse
events.The primary endpoint of this phase will be reduction in duration of hospitalization
stay between groups.

Patients will undergo clinical and laboratory safety evaluations daily. An algorithm for drug
suspension based on clinical and laboratory finding will be followed.
