Study summary

CD34+ stem cell selection in children, adolescents and young adults receiving partially matched family donor or matched unrelated adult donor allogeneic bone marrow or peripheral blood stem cell transplant will be safe and well tolerated and be associated with a low incidence of serious (Grade III/IV) acute and chronic graft versus host disease (GVHD).

Read the detailed description

The selection of CD34+ cells is associated with the simultaneous depletion of T cells that are responsible for severe acute and chronic graft versus host disease (GVHD). Successful engraftment is reported in adult patients with malignant and non-malignant disease who received CD34+ selected stem cells from HLA-matched or mismatched mobilized peripheral blood (PBSC) or bone marrow.

Study Design:

Selected patients defined in the eligibility criteria will enrolled on this study. Patients will receive one of either full intensity or reduced intensity regimen based on the patient's disease status, organ function and performance and determined by the PI and will have peripheral blood undergo CD34 selection.

Inclusion criteria

  • Adequate renal function defined as:Serum creatinine \<1.5 x normal, or or radioisotope >60 ml/min/m2 or an equivalent GFR as determined by the institutional normal range.

  • Infection: Patients with documented uncontrolled infection at the time of study entry are not eligible.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

What researchers measure

Primary outcomes

  1. The safety CD34+ stem cell selection

    serious adverse events will be monitored post transplant to determine if there is an increase vs. historical data related to the CD34+ selection

    Time frame: 100 days

Secondary outcomes

  1. Immune reconstitution (T, B, DC) following CD34+ selection

    immune subsets will be drawn post transplant to determine the rate of reconstitution post CD34+ transplant to determine if this process increases or decreases the reconstitution time.

    Time frame: 3 years
