Long COVID, Post Acute Sequelae

Brief summary

The project is described as a Phase 1 Clinical Safety Study intended to provide preliminary assessments of the safety, tolerability, and secondarily to be vigilant for signals of amelioration of symptoms associated with Post-Acute Sequelae of SARS-CoV-2 infection

Detailed description

The proposed study is a randomized single-center, double-blinded, placebo controlled standard of care plus study. Each participant will continue to receive standard of care treatment for their current diagnosis and be afforded the opportunity to add any additional care as needed that may include care for behavioral health concerns. In the proposed study, safety of a single administration of expanded autologous lines at a total dose exposure of 150 million cells (ATCell™) will be assessed. Each ATCell™ cell batch will be derived from ex vivo expanded stromal vascular fraction (SVF) of a participant's own adipose tissue. SVF is collected by liposuction and expanded. Briefly, ATCell suspended in Lactated Ringer's with 5% dextrose solution, or a placebo of Lactated Ringers 5% dextrose solution will be administered once to each participant. Safety will be evaluated through clinical assessments and laboratory test results comparing treatment cohort participant's baseline assessments and laboratory test results. Following completion of follow up period as defined in the schedule of events, the study will be unblinded, the results reviewed by the Institutional Review Board (IRB) and Human Research Protection Program (HRPP). Once safety has been reviewed by IRB/ HRPP, the study will be unblinded and participants that received the placebo treatment will be offered the opportunity to crossover and receive 150 million cell ATCell™ autologous treatment with the same monitoring and clinical support afforded to the first treatment cohort.

Interventions

PROCEDUREAdipose 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.

BIOLOGICALATCell

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.

Intervention model description

The proposed study is a randomized single-center, double-blinded, placebo controlled standard of care plus study. Once safety has been certified by IRB/ HRPP, the study will be unblinded and participants that received the placebo treatment will be offered the opportunity to crossover and receive 150 million cell ATCell™ autologous treatment with the same monitoring and clinical support afforded to the first treatment cohort

Design outcomes

Primary

MeasureTime frameDescription
Assessment of the Incidence of Serious Adverse Events (SAEs)Upon completion of final post treatment clinical visit of all participantsObserved 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)One week post administrationCompleted 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.
