About this trial

This is an open, prospective, dose-escalation clinical study to evaluate the safety and efficacy of Senl-T7 in patients with relapsed or refractory CD7+ acute T lymphoblastic leukemia or T lymphoblastic lymphoma.Meanwhile, PK/PD indexes of Senl-T7 were collected.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Diagnosis of relapsed/refractory T-cell lymphoblastic leukemia or T-cell lymphoblastic lymphoma: Induction therapy failed to achieve a complete remission of minor residual negative; Recurrence: after complete remission, any tumor load in the peripheral blood or bone marrow was 5%, or slightly residual positive, or new extramedullary lesions occurred;

CD7 expression in tumor cells was detected by flow cytometry;

Life expectancy greater than 12 weeks;

KPS or Lansky score≥60;

Disqualifiers

Any of the following cardiac criteria: Atrial fibrillation/flutter; Myocardial infarction within the last 12 months; Prolonged QT syndrome or secondary prolonged QT, per investigator discretion. Cardiac echocardiography with LVSF (left ventricular shortening fraction)<30% or LVEF(left ventricular ejection fraction)<50%; or clinically significant pericardial effusion. Cardiac dysfunction NYHA(New York Heart Association) III or IV (Confirmation of absence of these conditions on echocardiogram within 12 months of treatment);

Has an active GvHD;

Has a history of severe pulmonary function damaging;

With other tumors which is/are in advanced malignant and has/have systemic metastasis;

Trial outcomes

Primary outcomes

1

Safety: Incidence and severity of adverse events

To evaluate the possible adverse events occurred within first one month after CD7 CAR-T infusion, including the incidence and severity of symptoms such as cytokine release syndrome and neurotoxicity

Time frame
First 1 month post CAR-T cells infusion
2

Remission Rate

To obsere the efficacy of CAR-T cells after infusion, complete remission (CR), complete remission with incomplete recovery of blood cells (CRi), minimal tumor residual positive(MRD+) or negative (MRD-) CR/CRi, disease recurrence or progression (PD) will be used for evaluation.

Time frame
3 months post CAR-T cells infusion
