Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 4 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I/II Open-label Study to Evaluate The Safety and Efficacy of Abatacept in Subjects With Chronic Urticaria Who Have Had an Inadequate Response to Anti-histamine Therapy.

Arm Intervention/treatment
Experimental: Abatacept
4 doses of abatacept administered intravenously at baseline, 2 weeks, 4 weeks, and 8 weeks.
Drug: abatacept (Orencia ®)
4 doses of abatacept administered intravenously at baseline, 2 weeks, 4 week, and 8 weeks.
Other Name: orencia

Primary Outcome Measures :
  1. Number of Participants With Adverse Events [ Time Frame: baseline, 3 month and 6 months ]
    Participants were monitored for adverse events (AEs) at each visit. Cumulative AEs were tracked including specific AE, severity, and relationship on source documentation. Special attention was given to infusion-related events and hypersensitivity reactions. Assessment of Complete Blood Count (CBC) and Metabolic profile were also tracked.

Secondary Outcome Measures :
  1. Number of Participants With Clinically Detectable Improvement [ Time Frame: at each visit and at 3 months ]
    Evaluations will occur at each visit after the first infusion. At 3 months, response will be recorded and patients with improvement will be eligible to move into the steroid and/or antihistamine tapering portion of the study. Improvement was determined by a reduction in the number of hives.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Chronic active urticaria defined as symptoms > 50% of days or 3 days/week for more than 12 weeks

  • One of the following 3 conditions:

    • Previous or ongoing requirement for corticosteroids for symptom control OR
    • Prior steroid treatment with steroid discontinuation due to unacceptable morbidity
    • Previous or current use (without symptom control or with unacceptable morbidity: e.g., hypertension from cyclosporine, hemolysis from dapsone) of immunomodulatory treatment for urticaria (e.g., hydroxychloroquine, methotrexate, sulfasalazine, dapsone, cyclosporine, intravenous immunoglobulin (IVIg), mycophenolate, azathioprine, etc)
  • High baseline score for pruritis (at least 2 on a 3 point scale)
  • No underlying etiology clearly defined for urticaria
  • Patients should exhibit evidence of underlying autoimmunity of at least one of the following:

    • elevated erythrocyte sedimentation rate (ESR), C-Reactive Protein (CRP), anti-nuclear antibody (ANA)
    • extractable nuclear antigens
    • Thyroid antibodies
    • other autoantibodies (e.g., intrinsic factor, parietal cell, ovarian), *elevated complement levels
    • clinical characteristics suggestive of systemic autoimmune disease but without satisfying criteria for another diagnosis (e.g., arthralgias, myalgias, arthritis, low grade fever, significant fatigue associated with outbreaks)
    • family history of autoimmune disease including thyroid autoimmunity
    • a biopsy showing perivascular lymphocytic or mixed cellular infiltrate without vasculitis
  • Concomitant use of hydroxychloroquine, methotrexate, or sulfasalazine will be permitted if dose stable for at least 8 weeks
  • Concomitant use of steroids (≤ 15 mg/d Prednisone or equivalent) will be permitted if stable for 4 weeks and patient agrees to continue dose for the first 90 days
  • Negative pregnancy test (for women of child-bearing age)
  • Men and women of reproductive potential must agree to use an acceptable birth control during treatment and for 3 months after treatment
  • No planned elective surgical procedures for at least 6 months from day#1

Exclusion Criteria:

  • Current use of other immunosuppressive medications (cyclosporine, tacrolimus, sirolimus, IVIg, cyclophosphamide, mycophenolate mofetil, azathioprine). Any such medication will be discontinued for at least 4 weeks before study drug start.
  • Concomitant treatment with corticosteroids (≤ 15 mg/d), hydroxychloroquine, methotrexate, and sulfasalazine will be permitted if doses are stable at least 8 weeks

  • Pregnancy or lactation and all women must be willing to practice contraception through the study duration and for 3 months after discontinuing abatacept treatment.

    • Sexually active women of childbearing potential must use an effective method of birth control during the course of the study, in a manner such that risk of failure is minimized.
    • Prior to study enrollment, women of childbearing potential (WOCBP) will be advised of the importance of avoiding pregnancy during trial participation and the potential risk factors for an unintentional pregnancy.
    • In addition, men enrolled on this study will be informed of the risks to any sexual partner of childbearing potential and counseled to practice an effective method of birth control.
    • All WOCBP must have a negative urine pregnancy test within 7 days prior to first receiving the investigational product.
    • If the pregnancy test is positive, the subject will be excluded from the study.
    • In addition, all WOCBP will be instructed to contact the Investigator immediately if they suspect they might be pregnant (e.g., missed or late menstrual period) at any time during study participation and the Investigator will notify Bristol Myers Squibb (BMS) within 24 hours of becoming aware of a confirmed pregnancy in a subject participating in the study.

  • Inability to comply with study and follow-up procedures
