Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to explore the clinical and immunological efficacy of belimumab plus low dose IL-2 in systemic lupus erythematosus.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Given that belimumab and low dose interleukin-2 (IL-2) have been widespreadly applied in the treatment of systemic lupus erythematosus (SLE), this study designed a randomised, single center, prospective study to investigate the effects and safety of combined utilization of belimumab and low dose IL-2. SLE patients were allocated in each group randomly (n=10) and regularly administered belimumab (10mg/kg) with or without IL-2 (1 million IU). Then, we evaluated the improvement of clinical and laboratory indexes and monitored the changes of immune cell subsets and cytokines.

belimumab plus low dose IL-2

10mg/kg belimumab was intravenously injected to patients with systemic lupus erythematosus every month for 24 weeks.

Interleukine-2 was first added to the original treatment for systemic lupus erythematosus with 1 million IU qod for 12 weeks, injected subcutaneously at the outer side of upper arm, abdomen and thigh, then the same dose of IL-2 was injected once a week for 12 weeks subcutaneously.

Group Type EXPERIMENTAL

Belimumab

Intervention Type DRUG

Belimumab was intravenously administrated at a dose of 10mg/kg once a month for at least 24 weeks.

Interleukin-2

Intervention Type DRUG

Low lose interleukine-2 at a dose of 1 million IU was injected once every other day for 12 weeks, then the same dose of IL2 was injected once a week at the second stage for 12 weeks.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

\- 1. Male or female \>18 years of age at screening visits 2. Patients meet the American-European Consensus Group 2002 classification criteria 3. The patient must be informed in writing of the consent to participate in the trial and the patient is expected to be able to comply with the requirements of the study follow-up plan and other protocols.

4\. Dosing of antimalarials, prednisone or equivalent, cholinergic stimulants, and topical cyclosporine required to be stable for at least 4 weeks before screening and during study; maximum doses allowed:

* Hydroxychloroquine, 400 mg/day;
* Prednisone, 10 mg/day

Exclusion Criteria

* 1\. Any subject meeting any of the following criteria should be excluded: 1. Laboratory abnormality: • Hb≤9 g/dl • Neutrophil 10 mg/d) within 1 month.

2\. Serious complications: including heart failure (≥ New York Heart Association (NYHA) class III), renal insufficiency (creatinine clearance ≤ 30 ml/min), liver dysfunction (serum Alanine transaminase (ALT) or aspartate aminotransferase (AST) greater than three times the upper limit of normal, or total bilirubin greater than Normal upper limit) 3. Known allergies, hyperreactivity or intolerance of tofacitinib or its excipients.

4\. Have a serious infection needing hospitalization (including but not limited to hepatitis, pneumonia, bacteremia, pyelonephritis, Epstein-Barr virus (EBV), tuberculosis infection), or use intravenous antibiotics to treat infection in 2 months before the enrollment.

5\. Infection with HIV (HIV antibody positive serology) or hepatitis C (Hep C antibody positive serology). If seropositive, it is recommended to consult a doctor who has expertise in treating HIV or hepatitis C virus infection.

6\. Any known history of malignancy in the past 5 years (except for nonmelanoma skin cancer, non-melanoma skin cancer or cervical tumor without recurrence within 3 months after surgical cure prior to the first study preparation).

7\. Uncontrolled mental or emotional disorders, including a history of drug and alcohol abuse over the past 3 years, may hinder the successful completion of the study.

8\. Pregnant, lactating women (WCBP) are reluctant to use medically approved contraceptives during treatment and 12 months after treatment.
