About this study
Official title: A Phase II Trial of CD34+ Enriched Transplants From HLA-Compatible Related or Unrelated Donors for Treatment of Patients With Myelodysplastic Syndrome
This study will evaluate whether processing blood stem cell transplants using an investigational device (the CliniMACS system) results in fewer complications for patients who undergo transplant to treat myelodysplastic syndrome (MDS).
The CliniMACS system will be used to remove immune T-cells from the transplant donor's blood. Immune T-cells contribute to graft versus host disease (GVHD) - a serious complication that can happen after transplant. GVHD occurs when a patient's immune system attacks the donor's cells. The study aims to reduce the number of the donor immune T-cells thereby preventing or reducing the severity of GVHD.

What is being measured
The primary outcome is the main question the study is designed to answer.
Overall survival (OS)
OS is defined as time from transplant to death due to any cause
Measured: 2 years
Secondary outcomes (5)
Disease-free survival (DFS)
DFS is defined as the time from transplant to relapse, progression, death due to any cause, whichever occurs first.
Measured: 2 years
Transplant-related mortality (TRM)
Incidence of TRM defined as mortality related to the transplant rather than the disease
Measured: 2 years
Acute graft vs. host disease (GVHD)
Incidence of acute GvHD as graded using the International Bone Marrow Transplant Registry Severity Index, which includes assessment of skin, liver, and gut, grading each's severity from 0 to 4 (higher numbers reflecting the more severe disease). The overall assessment is based on the involvement and severity of each of the areas. A = Stage 1 skin involvement, no liver or gut involvement; B = Stage 2 skin involvement, Stage 1 to 2 gut or liver involvement; C = Stage 3 skin, liver or gut involvement; D = Stage 4 skin, liver, or gut involvement.
Measured: 2 years
Chronic graft vs. host disease (GVHD)
Incidence of chronic GvHD as graded using the NIH scoring system, which includes assessment of skin, mouth, eyes, GI tract, liver, lungs, joint/fascia, and genital tract and grades the severity of affected organs from 0 to 3 (higher scores reflecting the more severe disease). The overall assessment is based on the number of organs/sites with clinically significant functional impairment (i.e., score 2-3). No GVHD = no organs/sites with significant functional impairment; Mild GVHD = involves two or fewer organs/sites with significant functional impairment; Moderate GVHD = involves three or more organs/sites with significant functional impairment -OR- involves one or zero organs/sites with NO significant functional impairment; Severe GVHD = Major disability caused by chronic GVHD.
Measured: 2 years
Proportion of patients receiving optimal vs. suboptimal CD34+/CD3+ PBSC doses
Proportion of patients receiving optimal CD34+ (>5 × 10^6/kg) and CD3+ (< 5 ×10^4/kg) cell doses versus the proportion recurring suboptimal doses (<3 × 10^6/kg) CD34+ cells; and the proportion of patients receiving CD3+ T-cell doses (>5 × 10^4/kg)
Measured: Day 0

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will evaluate whether processing blood stem cell transplants using an investigational device (the CliniMACS system) results in fewer complications for patients who undergo transplant to treat myelodysplastic syndrome (MDS).
The CliniMACS system will be used to remove immune T-cells from the transplant donor's blood. Immune T-cells contribute to graft versus host disease (GVHD) - a serious complication that can happen after transplant. GVHD occurs when a patient's immune system attacks the donor's cells. The study aims to reduce the number of the donor immune T-cells thereby preventing or reducing the severity of GVHD.

How can a doctor refer a patient or contact the research team?
Contact Guenther Koehne, M.D., Ph.D. ((786) 596-2000, GuentherK@baptisthealth.net), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (OS) (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05617625, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Oct 2026.
