Adult moderate to serve SLE
Brief summary
The goal of this clinical trial is to test ATHENA CAR-T injection in adults with moderate to severe Systemic Lupus Erythematosus. The main question it aims to answer is: • To evaluate the safety and tolerability of ATHENA CAR-T. After screening, participants will be subjected to lymphodepletion regimen. After recovery, participants will be injected with ATHENA CAR-T injection and followed up to 24 months.
Detailed description
This study is a single center, one-arm, open label, phase I study aimed at evaluate the safety and effectiveness of ATHENA CAR-T treating moderate to severe SLE patients. A traditional 3+3 design is used with two doses. DLT is monitored. Safety and effectiveness are followed up until 24 months post infusion of ATHENA CAR-T. Besides safety monitoring, efficacy is evaluated via SLEDAI-2000, BILAG-2004, PGA.
Interventions
Phase 1 dose escalation (3+3): dose 1 and dose 2.
Intravenous injection of fludarabine.
Intravenous injection of cyclophosphamide.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dose Limiting Toxicity | 0~28 day after treatment | Dose Limiting Toxicity (DLT) is defined as AEs related to ATHENA CART from infusion till 28 days post infusion. |
| Frequency of AEs, SAEs, lab abnormalities, AESIs | 0 day to 24 months after treatment | Monitor grade and frequency of Adverse Events (AEs), Severe Adverse Events (SAEs), abnormal laboratory findings and Adverse Events of Special Interest (AESI). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy: Patients BILAG-2004 change compared with baseline | 0 to 16 weeks after treatment | Compare patients' BILAG-2004 (British Isles Lupus Assessment Group index 2004) value at baseline and week 4,8,12,16. Each organ system is graded from A to E, A indicate high disease activity while grade E indicate no disease activity now and then. A is assigned 9 points and E is assigned 0 points. |
| Efficacy: Percent of patients' PGA not worsen | 0 to 16 weeks after treatment | Measure percentage of patients whose PGA (Physician Global Assessment) is not worsen (increase LT 0.3 compare to baseline) at week 4,8,12,16. PGA is ranged 0 to 3, score 0 means no disease activity while score 3 means strong disease activity. |
| Percent of patients responded by BILAG-2004 | 0 to 16 weeks after treatment | Measure percentage of patients who responded by BILAG-2004 (no new A grade or NMT 1 new B grade) at week 4,8,12,16. |
| Efficacy: Immunologic parameters | 0 day to 24 months after treatment | Evaluate the change of immunological parameters. Including of concentration of IgG, IgA, IgM, C3, C4, unit g/L. |
| Efficacy: Immunologic parameters (cont) | 0 day to 24 months after treatment | Evaluate the change of immunological parameters. Including concentration of anti-dsDNA antibody, unit IU/ml. |
| Efficacy: Percent of patients achieved SRI-4 | 0 to 16 weeks after treatment | Measure percentage of patients who achieved SRI-4 (Systemic Lupus Erythematosus Responder Index-4) at week 4,8,12,16. SRI-4 response is achieved if SLEDAI-2000 score is lowered NLT 4pt compared to baseline, BILAG-2004 has no new A grade or NMT 1 new B grade, and PGA is not worsen (increase LT 0.3 compare to baseline). |
| Efficacy: Patients SLEDAI-2000 change compared with baseline | 0 to 16 weeks after treatment | Compare patients' SLEDAI-2000 (Systemic Lupus Erythematosus Disease Activity Index 2000) value at baseline and week 4,8,12,16. SLEDAI-2000 is an index of range 0 to 105. Higher score indicates stronger disease activity, a score NLT 15 means strong SLE activity. |
Other
| Measure | Time frame | Description |
|---|---|---|
| PD characteristics (cont) | 0 day to 24 months after treatment | Evaluate change of serum cytokine level, including but not limited to TNF-alpha and IFN-gamma, unit pg/ml, before and after infusion of ATHENA CAR-T. |
| PD characteristics | 0 day to 24 months after treatment | Evaluate change of CD19+ cell number, unit CD19 cell/l, before and after infusion of ATHENA CAR-T. |
| PK characteristics (cont) | 0 day to 24 months after treatment | Evaluate main PK parameters of ATHENA CAR-T, including Tmax, unit day. |
| PK characteristics | 0 day to 24 months after treatment | Evaluate main PK parameters of ATHENA CAR-T, including Cmax, unit CAR+ T cell/l. |
