About this study
Official title: Clinical Study of Senl-T7 CAR T Cells in the Treatment of Relapsed and Refractory CD7+ Acute T Lymphoblastic Leukemia and T Lymphoblastic Lymphoma
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.
Read the detailed description
The CARs consist of an anti-CD7 single-chain variable fragment（scFv）, a portion of the human CD137（4-1BB） molecule, and the intracellular component of the human CD3ζ molecule. Prior to CAR-T cell infusion, the patients will be subjected to preconditioning treatment. After CAR-T cell infusion, the patients will be evaluated for adverse reactions and efficacy.

Patients will be treated with CD7 CAR-T cells
| Study group | Role | What they receive |
|---|---|---|
| CD-7 CART | Experimental | Patients will be treated with CD7 CAR-T cells Receives: Biological: Senl-T7 |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: First 1 month post CAR-T cells infusion
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.
Measured: 3 months post CAR-T cells infusion

Questions about this trial
What is this clinical trial studying?
A study testing Senl-T7 in people with T-cell Acute Lymphoblastic Leukemia/Lymphoma, run by Hebei Senlang Biotechnology Inc., Ltd. at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xian Zhang (008618611636172, xian_zhang@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety: Incidence and severity of adverse events (time frame: First 1 month post CAR-T cells infusion). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
