Treatment With Human Umbilical Cord-derived Mesenchymal Stem Cells for Severe Corona Virus Disease 2019 (COVID-19)

18 agosto 2020 aggiornato da: Fu-Sheng Wang, Beijing 302 Hospital

A Phase II, Multicenter, Randomized, Double-blind, Placebo-controlled Trial to Evaluate the Efficacy and Safety of Human Umbilical Cord-derived Mesenchymal Stem Cells in the Treatment of Severe COVID-19 Patients

COVID-19 caused clusters of severe respiratory illness and was associated with 2% mortality. No specific anti-viral treatment exists. The mainstay of clinical management is largely symptomatic treatment, with organ support in intensive care for seriously ill patients. Cellular therapy, using mesenchymal stem cells has been shown to reduce nonproductive inflammation and affect tissue regeneration and is being evaluated in patients with ARDS. This clinical trial is to inspect the safety and efficiency of mesenchymal stem cells (MSCs) therapy for severe COVID-19.

Descrizione dettagliata

The Corona Virus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection has unprecedentedly spread in the worldwide and been declared as a pandemic by the world health organization. COVID-19 is characterized by sustained cytokines production and hyper-inflammation, can cause clusters of severe respiratory illness with a fatality rate around 2-5%. There are currently no prophylactic vaccine and no specific antiviral treatment agents available recommended for COVID-19. Therefore, it is urgent to find a safe and effective therapeutic approach to COVID-19.

During the last decade, the promising features of mesenchymal stem cells (MSCs), including their regenerative properties and ability to differentiate into diverse cell lineages, have generated great interest among researchers whose work has offered intriguing perspectives on cell-based therapies for various diseases. These findings seem to highlight that the beneficial effect of MSC-based treatment could be principally due by the immunomodulation and regenerative potential of these cells. MSCs could significantly reduce the pathological changes of lung and inhibit the cell-mediated immune inflammatory response induced by influenza virus in animal model . MSCs has been shown to reduce nonproductive inflammation and affect tissue regeneration and is being evaluated in patients with ARDS. Our phase I preliminary data of parallel assignment study(NCT04252118) showed that three doses of MSCs was safe in patients with COVID-19. Randomized control trial is needed to assess efficacy and safety.

The investigators will do a prospective, double-blind, multicentre, randomised trial to assess treatment with three intravenous doses of MSCs compared with placebo. 90 severe COVID-19 patients will be recruited in China. 60 patients will receive i.v. transfusion 3 times of MSCs (4.0*10E7 cells per time) and the standard of care as the treated group. In addition, the 30 patients will receive placebo and standard of care as control group.

Change in lesion proportion (%) of full lung volume from baseline to day 10, day28 and 90, change in consolidation/ ground-glass lesion proportion (%) of full lung volume from baseline to day 10, 28 and 90, time to clinical improvement in 28 days, mMRC (Modified Medical Research Council) dyspnea scale, 6-minute walk test, maximum vital capacity (VCmax), Diffusing Capacity (DLCO), oxygen saturation, oxygenation index, duration of oxygen therapy, side effects, immunological characteristics (immune cells, inflammatory factors, etc.) will be evaluated during the 90 days follow up.
