Brief Summary

A Clinical Study to Investigate the Safety, Efficacy, and Cellular Metabolism of CT1190B CAR-T Cell therapy, in Patients with Relapsed/Refractory B-Cell Non-Hodgkin Lymphoma.

Detailed Description

This is a single-arm, open-label, dose exploratory clinical study to evaluate the safety, efficacy, cellular pharmacokinetics, and pharmacodynamics of CT1190B cells in patients with B-NHL. It is planned to enroll 6-24 participants.

2. 18-75 years old;
3. Histologically or cytologically confirmed B-NHL;
4. Previously received at least 2 lines of systemic therapy;
5. Intolerance to last treatment, or have progressed on or after the last treatment and currently require therapy;
6. There are measurable target lesions;
7. Expected survival > 12 weeks;
8. Eastern Cooperative Oncology Group (ECOG) score 0-1;
9. Female participants of childbearing potential must have a negative pregnancy test at screening and prior to receiving preconditioning therapy and are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment and are absolutely prohibited from donating eggs for 1 year after receiving study treatment infusion during the study; male participants are willing to use a highly effective and reliable method of contraception for 1 year after receiving study treatment if they are sexually active with a female of childbearing potential. Sperm donation is absolutely prohibited for 1 year after receiving study treatment infusions during the study for all male participants.

Exclusion Criteria

1. Pregnant or lactating women;
2. Has HIV, syphilis infection, active hepatitis B virus infection (HBsAg positive and HBV-DNA above the detection limit), or active hepatitis C virus infection (HCV antibody and HCV-DNA positive);
3. Has any current uncontrolled active infection, including but not limited to participants with active tuberculosis (investigator 's judgment);
4. Participants' toxicities caused by previous treatment did not recover to Common Terminology Criteria for Adverse Events (CTCAE) ≤ Grade 1, except alopecia and other events that are judged tolerable by the investigator;
5. Has received treatment for the disease within 14 days before informed consent, including but not limited to cytotoxic therapy, monoclonal antibodies or ADCs, targeted therapy, radiotherapy, epigenetic therapy, or investigational agents, or invasive investigational medical devices within 14 days before informed consent.

9. Patients with any heart disease in the 6 months prior to screening;
10. Oxygen saturation < 92%,;
11. Presence of a second primary malignancy requiring treatment or not in complete remission within the past 2 years;
12. Major surgery within 2 weeks before informed consent or planned during the study period or within 4 weeks after giving study treatment (excluding local anesthesia such as cataract);
13. Participants are unable or unwilling to comply with the requirements of the study protocol or are otherwise unsuitable for participating in this clinical study in the investigator 's assessment;

Arm && Interventions

Group	Intervention	Description
CAR-T cells（ chimeric antigen receptor T cells）	CAR T cells	CT1190B cells infusion

Primary Outcome Measures

Name	Time	Method
Adverse Events (AE) after CT1190B infusion	12 months after CT1190B infusion	An assessment of severity grade will be made according to the National Cancer Institute Common Terminology Criteria
MTD and/or dose range	Up to 28 days after CAR-T cells infusion	Evaluate Dose limited toxicity and recommended dosage range after CT0991 infusion

Secondary Outcome Measures

Name	Time	Method
Overall response rate（ORR）	Evaluate at 4, 8, 12 weeks and 6,9,12month after CAR-T infusion	The proportion of patients with complete remission （CR） /partial response (PR) after CT1190B infusion.
Complete response rate (CRR)	12 months after CT1190B infusion	The proportion of patients with complete response(CR) after CT1190B infusion
Duration of remission(DOR)	12 months after CT1190B infusion	Participants achieving CR/PR will be included in the analysis set for DOR. DOR is defined as the time from the date of confirmed response until the date of disease relapse or death from any cause, whichever occurs first.
