Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study investigates how Telitacicept treatment affects transitional regulatory B lymphocyte subsets and plasma blasts in patients diagnosed with systemic lupus erythematosus (SLE). It aims to measure changes in specific cytokines associated with immune response in SLE patients who are on a stable treatment regimen. Participants must meet established criteria for SLE and have a certain level of disease activity to qualify for the study.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. The diagnosis meets the 2019 EULAR/ACR classification criteria for SLE;
2. Age 18-70 years old;
3. To be on a stable SLE regimen, participants were required to receive standard treatment at least 1 month prior to treatment with a biologic (Telitacicept);
4. Lupus activity Index score (SELENA-SLEDAI) ≥ 8 at screening;
5. Positive anti-nuclear antibody or anti-DSDNA antibody;
6. Combined antiphospholipid syndrome should meet the diagnostic criteria: that is, meet one clinical criterion and one laboratory criterion.

Exclusion Criteria:

1. Active infections (such as shingles, HIV infection, active tuberculosis, etc.) during the screening period;
2. Central nervous system disease (including epilepsy, psychosis, organic encephalopathy syndrome, cerebrovascular accident, encephalitis, central nervous system vasculitis) caused by SLE or not caused by SLE in the last 2 months;
3. Have active hepatitis or a history of severe liver disease;
4. Patients with immune deficiency, uncontrolled severe infection, and active or recurrent digestive ulcer;
5. Pregnant women, breastfeeding women and men or women who have planned to have a baby in the last 12 months;
6. Allergic reaction: history of allergic reaction to human biological products;
7. Those who received live vaccine within the last month;
8. Participants who have participated in any clinical trial within 28 days prior to initial screening/or 5 times the half-life of the study compound (taking an older time);
9. B cell targeted therapy, such as rituximab or epazumab, within one year;
10. Use tumor necrosis factor inhibitors and interleukin-receptor blockers within one year;
11. Patients receiving intravenous gamma globulin (IVIG), prednisone ≥ 100 mg/d for more than 14 days within one month or undergoing plasmapheresis;
12. Psychopaths with depression or suicidal thoughts.
