Treatment of Refractory/Relapsed Non-Hodgkin Lymphoma With CD19-TriCART Cell Therapy

Phase 1

• Conditions: Non-hodgkin Lymphoma,B Cell
• Interventions: Biological: CD19-TriCAR-T

• Registration Number: NCT03720496
• Lead Sponsor: Timmune Biotech Inc.

Brief Summary

This is a single arm, open-label, phase Ⅰ study, to determine the safety and efficacy of CD19-TriCAR-T, an autologous tri-functional anti- CD19 chimeric antigen receptor (CAR)-positive T cell therapy, in Refractory/ Relapsed CD19 Positive Non-Hodgkin Lymphoma (NHL).

Detailed Description

The tri-functional anti-CD19 chimeric antigen receptor contains an anti-CD19 scFv, a PD-L1 blocker, and a cytokine complex, enabling the CD19-TriCAR-T to simultaneously targeting the CD19 positive NHL cells，blocking the inhibitory PD-L1 signal and stimulating T/NK cell activation and expansion.

• Sex: All
• Target Recruitment: 6

Inclusion Criteria

1. All subjects must personally sign and date the consent form before initiating any study specific procedures or activities;

2. All subjects must be able to comply with all the scheduled procedures in the study;

3. Histologically or cytologically confirmed CD19 positive non-Hodgkin lymphoma;

4. At least one measurable lesion per revised IWG Response Criteria;

5. Aged 18 to 69 years;

6. Expected survival ≥12 weeks;

7. Eastern cooperative oncology group (ECOG) performance status of ≤2;

8. Systematic usage of immunosuppressive drug or corticosteroid must have been stopped for more than 4 weeks;

9. All other treatment induced adverse events must have been resolved to

   ≤grade 1;

10. Laboratory tests must fulfill the following criteria: ANC ≥ 1000/uL, HGB >70g/L, Platelet count ≥ 50,000/uL, Creatinine clearance ≤1.5 ULN, Serum ALT/AST ≤2.5 ULN, Total bilirubin ≤1.5 ULN (except in subjects with Gilbert's syndrome);

Exclusion Criteria

1. Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring IV antimicrobials for management. Simple UTI and uncomplicated bacterial pharyngitis are permitted if responding to active treatment;
2. Patients with symptomatic central nervous system metastasis, intracranial metastasis, and cancer cells found in cerebrospinal fluid are not recommended to participate in this study. Symptom free or post-treatment stable disease or disappearance of lesions should not be excluded. The specific selection is ultimately determined by the investigator;
3. Lactating women;
4. Active infection with hepatitis B (HBsAG positive) or hepatitis C virus (anti-HCV positive);
5. Known history of infection with HIV;
6. Subjects need systematic usage of corticosteroid;
7. Subjects need systematic usage of immunosuppressive drug;
8. Planed operation, history of other related disease, or any other related laboratory tests restrict patients for the study;
9. Other reasons the investigator think the patient may not be suitable for the study.
