Study Summary

This trial is studying a new way to give a haploidentical stem cell transplant (using donor cells that have been enriched with regulatory T cells) to people with relapsed or refractory acute myeloid leukemia or myelodysplastic syndrome.

Who is the study for?
Adults aged 18-65 with relapsed/refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndromes (MDS), who have a compatible family donor, can join this trial. Participants need good heart, lung, and kidney function and must not be pregnant or breastfeeding. They should agree to use contraception during the study.Check my eligibility
What is being tested?
The trial is testing an experimental stem cell transplant method using radiation, chemotherapy (Fludarabine, Thiotepa, Cyclophosphamide plus Mesna), and infusions of Treg-enriched donor cells along with unmodified haplo donor T cells and CD34+ Peripheral Blood Stem Cells in patients with AML/MDS.See study design
What are the potential side effects?
Potential side effects include reactions to the infusion of cells, organ damage from radiation or chemotherapy drugs like Fludarabine and Cyclophosphamide. There's also a risk of infection due to immune system suppression by treatments.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Could you elaborate on prior research involving Treg-enriched donor cells?

"Currently, there are 161 Phase 3 trials and a total of 900 active trials for Treg-enriched donor cell. These medical studies span across 28,633 different locations with the majority being located in Philadelphia, Pennsylvania."

Answered by AI

For what purposes is Treg-enriched donor cell typically utilized?

"Treg-enriched donor cell is a common intervention for multiple sclerosis, but it can also be effectively used to manage leukemia, myelocytic, acute and retinoblastoma cases as well as histiocytic lymphoma."

Answered by AI

Can I be considered as a potential participant in this research project?

"This medical trial is actively seeking 10 patients who have been diagnosed with Myelodysplastic Syndromes and are of legal age. Additionally, the patient must possess an Eastern Cooperative Oncology Group Performance Status score no higher than 2 (KarnofskyScore ≥60) and be ineligible for myeloablative HCT due to their advanced years; minors cannot participate in this study at present, though they may qualify for future paediatric trials."

Answered by AI

Do any positions remain available in this research program?

"Affirmative. According to information accessible on clinicaltrials.gov, this experiment is presently recruiting participants. It was initially published on December 1st 2021 and its most recent update occurred June 24th 2022. Recruitment campaigns are currently targeting 10 potential patients from a single site."

Answered by AI

How many participants are eligible for this investigation?

"Affirmative. The information hosted on clinicaltrials.gov verifies that this study is actively recruiting patients, which was first posted on December 1st 2021 and last amended June 24th 2022. Ten participants need to be recruited from a single medical centre."

Answered by AI

Is the Food and Drug Administration sanctioning Treg-enriched donor cell treatments?

"The safety of Treg-enriched donor cells is rated as a 1 on our team's scale due to the preliminary nature of this Phase 1 trial, which has yet to yield comprehensive results for either efficacy or safety."

Answered by AI

Is this clinical trial open to people over a certain age threshold?

"To be eligible for this clinical trial, individuals must between 18 and 65 years old. In contrast, there are 989 studies aiming to recruit participants under the age of 18 and 2982 targeting those over 65."
