About this trial

The objective of this study is to assess the safety and efficacy of anti-CD7 CAR T-cells in patients with refractory or relapsed T-lineage acute lymphoblastic leukemia (T-ALL).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Minimum level of pulmonary reserve defined as Grade ≤ 1 dyspnoea and oxygen saturation (SpO2) of > 95% on room air

Left ventricular systolic function (LVSF) ≥ 28% confirmed by echocardiogram, or left ventricular ejection fraction (LVEF) ≥ 45% confirmed by echocardiogram within 3 months of screening

Karnofsky (age ≥ 16 years) or Lansky (age < 16 years) performance status ≥ 50 at screening

Normal Age-adjusted eGFR Creatinine Clearance within 3 months of screening

Disqualifiers

Failure to meet any of the inclusion criteria

Patients who test positive on urine pregnancy testing and are pregnant or are lactating

Concomitant genetic syndromes associated with bone marrow failure states, such as Fanconi anaemia, Kostmann syndrome, Schwachman syndrome, or any other bone marrow failure syndrome with the exception of Down syndrome

Prior malignancy, except carcinoma in situ of the skin or cervix treated with curative intent and no evidence of active disease

Trial outcomes

Primary outcomes

1

Proportion of participant who are flow cytometry minimal residual disease (MRD) negativity at 1 month after Anti-CD7 PEBL CAR T-cell infusion.

MRD levels will be determined by flow cytometry. The target sensitivity of flow MRD is \<0.01% when available.

Time frame
30 days

Secondary outcomes

1

Proportion of participant who are minimal residual disease (MRD) negative with molecular base assay at the end of 1 month after Anti-CD7 PEBL CAR T-cell infusion.

MRD levels will be determined by molecular based MRD by Ig/TCR. PCR and oncogene fusion transcript (OFT).

Time frame
30 days
2

Proportion of patient who shows CAR T-cell persistence by immunophenotyping using flow cytometry in bone marrow, peripheral blood and CSF samples at multiple study time points following CAR T cell infusion

Flow cytometry will be performed on bone marrow, peripheral blood and CSF samples at multiple study time points following CAR T cell infusion

Time frame
1 month to 5 years
