Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team to understand any specific requirements.

What data supports the effectiveness of the treatment Stem Cell Therapy for Long COVID Syndrome?

Research shows that mesenchymal stem cell therapy has been studied for severe COVID-19 patients, with follow-up results indicating potential benefits. Additionally, adipose-derived mesenchymal stem cells have been evaluated for improving symptoms in post-COVID-19 syndrome, suggesting possible effectiveness for long COVID.12345

Is stem cell therapy safe for humans?

Research on stem cell therapy, particularly using mesenchymal stem cells (MSCs), shows it is generally safe for humans. Studies on COVID-19 patients found no serious side effects, with only minor issues like temporary fever or facial flushing in some cases.14678

How is stem cell treatment different for Long COVID?

Stem cell treatment for Long COVID is unique because it uses mesenchymal stem cells (MSCs) to repair damaged tissues and modulate the immune system, which is different from other treatments that may not address tissue repair or immune regulation. This approach is particularly promising for conditions like Long COVID, where persistent symptoms may result from immune dysregulation and tissue damage.1491011

What is the purpose of this trial?

The purpose of this research study is to test the safety and benefit of a human cord blood derived stem cell infusion as a treatment for individuals with post COVID-19 neurological problems. Participants in the study will have 6 clinic visits over a 12 to 14 mo. period with each visit lasting 2 to 6 hours. Participants will receive 1 stem cell infusion at study visit #3. Participants will have a brain PET and MRI scan at the baseline and 6mo. post-infusion visits. Follow-up safety assessments will be conducted at 6mo. and 1yr. after the stem cell infusion.

Eligibility Criteria

This trial is for adults aged 18-55 who have had COVID-19 and are now experiencing long-term neurological symptoms like anxiety, depression, pain, sleep issues, or 'brain fog'. They must be able to consent and communicate in English or Spanish. People with severe psychiatric conditions, recent infections, kidney/liver disease, cancer, immunosuppression including HIV+, substance dependencies that affect participation, significant lung disease requiring oxygen supplementation or medication use cannot join. Also excluded are pregnant women not using birth control and those unable to undergo required tests.

Inclusion Criteria

I had COVID-19 and now have lasting nerve or brain problems.
My health has been significantly affected by Covid-19.
I've had symptoms like anxiety, pain, sleep issues, or 'brain fog' for 6 months after COVID-19.

Treatment Details

Interventions

  • Stem Cell
Trial Overview The study is testing the safety and effectiveness of a stem cell infusion derived from human cord blood as a treatment for post-COVID-19 neurological symptoms. Participants will visit the clinic six times over about a year for monitoring which includes brain scans (PET and MRI) before treatment and six months after receiving one stem cell infusion.
Participant Groups
4Treatment groups
Experimental Treatment
Group I: 8x10^6 Cells/kg Dose GroupExperimental Treatment1 Intervention
The next cohort of 3 subjects will receive one stem cell infusion of 8x10\^6 Cells/kg. If no infusion related AE/SAE are found, the next cohort will receive the next highest stem cell dose.
Group II: 6x10^6 Cells/kg Dose GroupExperimental Treatment1 Intervention
The next cohort of 3 subjects will receive one stem cell infusion of 6x10\^6 Cells/kg. If no infusion related AE/SAE are found, the next cohort will receive the next highest stem cell dose.
Group III: 4x10^6 Cells/kg Dose GroupExperimental Treatment1 Intervention
This is a adaptive Baysian dose escalation study. The first 3 subjects will receive one stem cell infusion of 4x10\^6 Cells/kg. If no infusion related AE/SAE are found, the next cohort will receive the next highest stem cell dose.
Group IV: 10x10^6 Cells/kg Dose GroupExperimental Treatment1 Intervention
The last cohort of 3 subjects will receive one infusion of 10x10\^6 Cells/kg.
