Brief Summary

Stem cell therapy has emerged as a revolutionary treatment for diseases that were considered untreatable only a few years ago. Umbilical cord-derived mesenchymal stem cells (UCMSCs) have been shown to repair damaged liver, kidney, heart, pancreas, skin, cartilage, and cornea in animal models and several human trials. In addition to cellular replacement through regeneration, UCMSCs mediate through paracrine signaling pathways resulting in immune modulation. Clinical manifestations of coronavirus disease 2019 (COVID-19), are believed to arise from septic shock and cytokine storm that cause acute respiratory dysfunction and acute cardiac injury. There is presently no cure for the COVID-19 viral disease; however, multi-treatment strategies are being examined. During the past two months, four reports were published that suggest, mesenchymal stem cells (MSCs), owing to their powerful immunomodulatory ability, may prevent the cytokine storm and thus reduce the COVID-19 related morbidity. All studies reported that COVID-19 patients responded favorably to MSCs therapy. These reports, taken together with the previous successes of stem cell therapy in animal models, the investigators, a seven-institution consortium, propose to explore the efficacy of UCMSC treatment in COVID-19 patients at Jinnah hospital, Lahore. The investigators propose to administer UCMSCs in patients with acute pulmonary inflammation due to COVID-19 infection with moderate to severe symptoms. In the first cohort of 15 patients, UCMSCs will be administered with three intravenous infusions of 500,000 UCMSCs per Kg body weight each on days 1, 3, and 5. The second group of five patients serving as control will only receive standard treatment. During the 30-day post-infusion period, a battery of tests will be performed to evaluate the safety and efficacy of the UCMSCs treatment. In parallel, the investigators propose a comparative study to determine COVID-19 viral count by quantitative real-time PCR and through viral coat protein ELISA, developed in the investigator advisor lab (Dr. Tauseef Butt, Progenra Inc. Philadelphia, USA) with the ultimate objective to locally developing a rapid diagnostic assay.

Detailed Description

Isolation and characterization of human umbilical cord-derived mesenchymal stem cells (UCMSCs): Human umbilical cord tissues along with informed consent forms will be collected from hepatitis B, C, and COVID-19 virus-negative women with healthy pregnancies during the Cesarean Section surgery after completion of gestation period. The cord tissue will be transported in sterile 1x phosphate-buffered saline (PBS) containing 200 units/ml penicillin and 200 µg/ml streptomycin on ice. In the biosafety cabinet, the cord will be washed with 4-5 changes of sterile 1x PBS and placed in a Petri plate with 15 ml PBS. The cord will be gently scraped with a surgical blade to remove any dead cells. A 9 cm umbilical cord will be cut into three equal pieces and wash thoroughly to remove blood clots, umbilical cord arteries, and veins. Segments will be washed three times with PBS and minced. The minced pieces will be incubated in 17.5 ml of collagenase solution (201 U/ml collagenase type I in serum-free DMEM-HG) in a 50 ml conical tube for ~3.5 hours in an incubator at 5% CO2, 95% humidity at 37⁰C. After ~3.5 hours, the digested lysate will pass through a strainer and will be diluted three times with 1x PBS. Following centrifugation, the cells will be seeded into two 25 cm2 flasks and will be placed in an incubator at 5% CO2, 95% humidity at 37⁰C. The flasks will be fed with fresh media (DMEM-HG supplemented with 20% FBS and 1% antibiotic solution) every third day. At around day 18, cells will reach up to 85% confluency and will be transferred in two 75 cm2 flasks with media replaced at alternate days. UCMSCs at P3 will be characterized using different specific antibodies. Cells at P3 will be used for transplantation in patients. Fifteen (15) subjects will be treated with three intravenous infusions (IV) of 500,000 UCMSCs per Kg body weight delivered via peripheral intravenous infusion.
