Study Arms (2)

Low-dose IL-2

EXPERIMENTAL

After a 4-week screening period, patients received IL-2 at a dose of 1 million IU subcutaneously every other day. After the initiation of the therapy, patients could continue with concurrent medication but were prohibited from changing or adding immunosuppression therapy during the course of the study with a 12-week observational followed up.

Drug: Low-dose IL-2

placebo

PLACEBO COMPARATOR

After a 4-week screening period, patients received placebo subcutaneously every other day. After the initiation of the therapy, patients could continue with concurrent medication but were prohibited from changing or adding immunosuppression therapy during the course of the study with a 12-week observational followed up.

Drug: Placebo

Interventions

After a 4-week screening period, patients received IL-2 at a dose of 1 million IU subcutaneously every other day. After the initiation of the therapy, patients could continue with concurrent medication but were prohibited from changing or adding immunosuppression therapy during the course of the study with a 12-week observational followed up.

Low-dose IL-2

After a 4-week screening period, patients received placebo subcutaneously every other day.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female 18-70 years of age at time of screening.
  • Diagnosis of Behçet's Disease (according to the 1989 ICBD) for ≥3 months before screening.
  • Active oral ulcer at time of screening.
  • Patients on corticosteroids (≤1 mg/kg/d prednisone or equivalent), DMARDs (e.g. methotrexate, hydroxychloroquine, azathioprine, MMF, leflunomide, ciclosporin etc.), must have been on a stable dose for 4 weeks prior to receiving the first infusion of study medication and expected to remain on this dose throughout the study. If the registered doctor plans to quit using current DMARDs or glucocorticoids, the washout period needs to be followed before patients join the groups. Each drug needs to meet the following washout period
  • glucocorticoids - 2 weeks
  • DMARDs (including mmethotrexate, hydroxychloroquine, azathioprine, MMF, leflunomide, and ciclosporin ) - 4 weeks
  • IVIg or cyclophosphamide - 2 months
  • Rituximab - 6 months
  • other bDMARDs(e.g. Infliximab, Adalimumab, Enanercept etc.) - 12 weeks
  • Given their written informed consent to participate in the trial and expected to be able to adhere to the study visit schedule and other protocol requirements.

You may not qualify if:

  • BD-related active major organ involvement requiring immunosuppressive therapy, e.g., pulmonary (e.g., pulmonary artery aneurysm), vascular (e.g., thrombophlebitis, recurrent malignant aneurysms), gastrointestinal (e.g., gastrointestinal ulcers), and central nervous system (e.g., meningoencephalitis).
  • High-dose glucocorticoid (\>1mg/kg/d) usage within 1 month.
  • Severe comorbidities: including Heart failure (≥ grade III NYHA); Renal insufficiency (creatinine clearance ≤30 ml/min); Hepatic insufficiency (serum ALT or AST \>3 times the ULN, or total bilirubin \>ULN for the central laboratory conducting the test).
  • Other severe, progressive or uncontrolled hematologic, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, or cerebral disease (including demyelinating diseases such as multiple sclerosis).
  • Known allergies, hypersensitivity, or intolerance to IL-2 or its excipients.
  • History of severe allergic reaction to monoclonal antibodies or to murine, chimeric, or human proteins or their excipients.
  • Had a severe infection (including, but not limited to hepatitis, pneumonia, sepsis, or pyelonephritis); had been hospitalized for an infection; or had been treated with IV antibiotics for an infection, within 2 months prior to the first administration of study agent.
  • Chest radiograph within 3 months prior to the first administration of study agent that showed an abnormality suggestive of a malignancy or current active infection, including TB.
  • Infected with HIV (positive serology for HIV antibody) or hepatitis C (positive serology for Hep C antibody). If seropositive, consultation with a physician with expertise in the treatment of HIV or hepatitis C virus infection was recommended.
  • Infected with hepatitis B virus. For patients who were not eligible for this study due to hepatitis B virus test results, consultation with a physician with expertise in the treatment of hepatitis B virus infection was recommended.
  • Had any known malignancy or has a history of malignancy within the previous 5 years (with the exception of a nonmelanoma skin cancer that had been treated with no evidence of recurrence for ≥3 months before the first study agent administration or cervical neoplasia with surgical cure).
  • Had uncontrolled psychiatric or emotional disorder, including a history of drug and alcohol abuse within the past 3 years that might prevent the successful completion of the study.
  • Received, or was expected to receive, any live virus or bacterial vaccination within 3 months before the first administration of study agent, during the study, or within 4 months after the last administration of study agent. Had a BCG vaccination within 12 months of screening.
  • Pregnancy, lactation or women of child-bearing potential (WCBP) unwilling to use medically approved contraception whilst receiving treatment and for 12 months after treatment has finished.
  • Men whose partners are of child-bearing potential but who are unwilling to use appropriate medically approved contraception whilst receiving treatment and for 12 months after treatment has finished.
