Long COVID | Procedure: Adipose Tissue Harvest Biological: ATCell | Phase 1 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 20 participants |

---|---|
Experimental: ATCell Treatment Group
A single administration of expanded autologous lines at a total dose exposure of 150 million cells ("ATCell™") will be administered to this group.
|
Procedure: Adipose Tissue Harvest
Local Anesthesia will be administered. A Stab wound will be created at the harvest site through which a 3.0 or 2.5 mm cannula will be inserted to suction fat using the "syringe" (i.e. manual) technique. A total of 100 cc of lipoaspirate will be collected by manual draw of the adipose tissue into syringes.
Other Name: Liposuction Biological: ATCell Infusion of the study medication at the rate of 575 mL/HR (500ml of LRD5 plus 75ml of ATCell suspended in LRD5) and continue until all received trial medication has been delivered.
Other Name: Autologous Adipose Derived Mesenchymal Stem Cells |
Placebo Comparator: Placebo
a single administration of Placebo (Sham Treatment) IV infusion of Ringers Lactate with 5% Dextrose will be administered to this group.

- Assessment of the Incidence of Serious Adverse Events (SAEs) [ Time Frame: Upon completion of final post treatment clinical visit of all participants ]Observed Adverse Events (AE's) in the placebo control group will be compared to observed AE in the experimental treatment, if any, in order to assess safety of the experimental treatment.
- Assessment of change in Health Status using the 36 item Short Form Health Survey (SF-36) [ Time Frame: One week post administration ]Completed by Participant as a part of physician visits at baseline, and once per week following treatment. Scores of completed SF-36 will be numerically determined and compared to baseline. Changes against baseline will be represented numerically (positive or negative).The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.
- Assessment of change in Health Status using the 36 item Short Form Health Survey (SF-36) [ Time Frame: Two weeks post administration ]Completed by Participant as a part of physician visits at baseline, and once per week following treatment. Scores of completed SF-36 will be numerically determined and compared to baseline. Changes against baseline will be represented numerically (positive or negative).The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.

Changes against baseline will be represented numerically (positive or negative).The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.
- Assessment of change in Health Status using the 36 item Short Form Health Survey (SF-36) [ Time Frame: Four weeks post administration ]Completed by Participant as a part of physician visits at baseline, and once per week following treatment. Scores of completed SF-36 will be numerically determined and compared to baseline. Changes against baseline will be represented numerically (positive or negative).The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.
