The disease caused by the new coronavirus, SARS-CoV-2, called COVID-19, it has considered a worldwide pandemia by the WHO. Suddently, it produces a lot of patients severe ill, in a little geographic area, that could surpase the resourses of the any health system in the world. There is no documentation of an effective alternative for the treatment of the severe ill patients, that can reduce the mortality or the adverse events suffered by these people. It is has suggested the usefulness of the Mesenchymal Stem cells (MSC) for the management of these patients, thanks to their direct and indirect antiviral capacity, and its potency as immunomodulator, that could ameliorate the lung disease and the severity of COVID-19.
Objetive:
Evaluate the effect of MSC derived from human umbilical cord compared with placebo, over the
clinical progresion and mortality of hospitalized COVID-19 patients.
Metodology:
Fase II, controled clinical trial, double blinded, compared with placebo, with paralel
groups, and one to one asignation. It will be included patients between 18 and 79 years old,
hositalized in general room (respiratory isolation area) with confirmed COVID-19 diagnosis.
It will be excluded those who have indication for management in Intensive Care Unit, have any
condition that seriusly affect their survival, pregnant whomen or breast feeding, those who
have an advanced hearth failure, HIV infected, those who have a bacterial or fungal
uncontroled infection, those who require permanent immunosupresive therapy or have had an
organ trasplant, those who have no possibility to sign the informed consent format or are
involved in another clinical trial with drugs or interventions.
It will vinculate 30 patients randomly assigned, by centralized electronic assignation
sequence, for the experimental group who will received 1*10^6 cells/Kg extracted from human
umbilical cord or to placebo group.
The primary result it will be a composed point of time to the occurrence of the clinical
detriment or the death (the first that occurs) and the secondary result will be the
components of each primary point, the clinical recovery, the time to the time to the
discharge from the hospital, and the clinical follow-up, including respiratory function, and
markers of inflammation, haematological and kidney, in addition of the safety markers.
It will be done a comparison of the incidence rates, by ratio of incidence rates and their
respective confidence interval. It will be construct Kaplan-Meier curves that will compared
by the statics of logaritmic rank (log-rank test).
It will be developed a multivariate analysis, with the Cox proportional risks methodology,
estimating the Hazard Ratio epidemiologic.
