There is one clinical trial.
Currently, the growing epidemic of a new coronavirus infectious disease (Covid-19) is wreaking havoc worldwide, which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is a RNA virus that display high similarity in both genomic and proteomic profiling with SARS-CoV that first emerged in humans in 2003 in China. Therefore, preventing and controlling the pandemic occurrences are extremely urgent as a global top priority. Due to the lack of effective antiviral drugs, patients may be treated by only addressing their symptoms such as reducing fever. Clinical autopsies from SARS-CoV-infected patients demonstrated that there were major pathological changes in the lungs, immune organs, and small systemic blood vessels with vasculitis. However, the detection of SARS-CoV were primarily found in the lung and trachea/bronchus, but was undetectable in spleen, lymph nodes, bone marrow, heart and aorta, highlighting the overreaction of immune responses induced by viral infection were really harmful, resulting in the pathogenesis of lungs, immune organs, and small systemic blood vessels. To this respect, immune modulation strategy may be potentially beneficial to enhance anti-viral immunity and efficiently reduce the viral load, improve clinical outcomes, expedite the patient recovery, and decline the rate of mortality in patients after being infected with SARS-CoV-2. Tianhe Stem Cell Biotechnologies Inc. has developed a novel globally-patented Stem Cell Educator (SCE) technology designed to reverse the autoimmune response in Type 1 diabetes (T1D), Alopecia Areata (AA) and other autoimmune diseases. SCE therapy uses human multipotent cord blood stem cells (CB-SC) from human cord blood. Their properties distinguish CB-SC from other known stem cell types, including mesenchymal stem cells (MSC) and hematopoietic stem cells (HSC). Several clinical studies show that SCE therapy functions via CB-SC induction of immune tolerance in autoimmune T cells and restore immune balance and homeostasis in patients with T1D, AA and other inflammation-associated diseases. To correct the overreaction of overreaction of immune responses, the investigators plan to treat SARS-CoV-2 patients with Stem Cell Educator therapy.
Description: The feasibility will be evaluated by the number of Covid-19 patients who were unable to complete SCE Therapy.Measure: Determine the number of Covid-19 patients who were unable to complete SCE Therapy Time: 4 weeks
Description: Measurements of immune markers' changes will be preformed by flow cytometry such as activated T cells. Peripheral blood mononuclear cells (PBMC) will be collected at 1, 3, 6, 9, 12, 28 day post the SCE therapy.Measure: Examine the percentage of activated T cells after SCE therapy by flow cytometry Time: 4 weeks
Description: Measurements of immune marker's changes will be preformed by flow cytometry such as the percentage of Th17 cells. Peripheral blood mononuclear cells (PBMC) will be collected at 1, 3, 6, 9, 12, 28 day post the SCE therapy.Measure: Assess the percentage of Th17 cells after SCE therapy by flow cytometry Time: 4 weeks
Description: Patients will be monitored for their chest imaging every 3 - 5 days for 4 weeks after receiving SCE therapy.Measure: Chest imaging changes by computed tomography (CT) scan of the chest Time: 4 weeks
Description: To determine the viral load by real time RT-PCR, samples of blood, sputum, nose / throat swab will be collected from patients during the follow-up studies after receiving SCE therapy.Measure: Quantification of the SARS-CoV-2 viral load by real time RT-PCR Time: 4 weeks
