Brief Summary:
This is a randomized phase II placebo controlled clinical trial. Active arm: Allogeneic Wharton's jelly derived MSCs (WJ-MSCs). Both groups will receive standard of care treatment for COVID (e.g. dexamethasone)

Condition or disease Intervention/treatment Phase
Covid19 Biological: Allogeneic Wharton's jelly-MSCs (WJ-MSC) Other: Placebo Phase 2

Detailed Description:

Allogeneic Wharton's jelly-MSCs (WJ-MSC) will be provided by NextCell Pharma under the commercial name of ProTrans®. ProTrans® will be administered at a fixed dose of 100 million cells per patient in a single infusion at bedside.

Placebo: Sodium chloride buffer supplemented with 5% HSA and 10% DMSO same volume and mode of administration as treatment group (NextCell Pharma).

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Allogeneic Wharton's jelly-MSCs (WJ-MSC)
Intravenous administration, 1 dose, for 20 minutes
 Biological: Allogeneic Wharton's jelly-MSCs (WJ-MSC)

The product is provided cryopreserved by NextCell Pharma. The cells are frozen in cryobags at a concentration of 2 × 107 cells/ml in 5% Human Serum Albumin (HSA) and 10% dimethylsulfoxide (DMSO). One cryobag contains one dose. The bags are frozen in a controlled rate freezer and directly transferred to -190 ºC for storage until the time of infusion.

Cryobags are thawed at bedside and diluted in 100 ml of saline prior to administration. Cells will be delivered at a rate of 5 million cells per minute over a total of 20 minutes.

Other Name: Protrans
Placebo Comparator: Placebo
Intravenous administration, 1 dose, for 20 minutes
 Other: Placebo
