Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Male or female adults ≥ 18 years of age at the time of the first dose of study drug;
• Written informed consent obtained from the patient; or patient's legal representative;
• Meet at least 4 of the 11 revised ACR classification criteria for SLE (see Appendix A) (ACR,1999);
• Have positive ANA test at ≥ 1:80 serum dilution in the past or at screening;
• Have at least one system with a score of A or two systems with a score of B on the BILAG index at screening, or have a SELENA-SLEDAI score ≥ 6;
• Sexually active women, unless surgically sterile (including tubal ligation) or at least 2 years post-menopausal, must use an effective method of avoiding pregnancy (including oral, injectable, transdermal, or implanted contraceptives, intrauterine device, diaphragm with spermicide, cervical cap, abstinence, sterile sexual partner) in addition to the use of condoms (male or female condoms with spermicide) from screening through the end of the study. Cessation of birth control after this point should be discussed with a responsible physician. Sexually active men, unless surgically sterile, must likewise practice two effective methods of birth control (condom with spermicide or abstinence) and must use such precautions from Study Day 0 through the end of the study.
• Ability to complete the study period, including follow-up period through Study Day 350; and
• Willing to forego other forms of experimental treatment during study.

Exclusion Criteria:

• Have received MEDI-545 within 120 days prior to screening or have either detectable levels of MEDI-545 or anti-MEDI-545 antibodies (positive at > 1:10 serum dilution) in serum at screening;
• History of allergy or reaction to any component of the study drug formulation;
• Have received prednisone > 20 mg/day (or an equivalent dose of another oral corticosteroid)within 14 days before randomization/entry;
• Have received the following dosages of medications within 28 days before randomization/entry: hydroxychloroquine > 600 mg/day, mycophenolate mofetil > 3 g/day,methotrexate > 25 mg/week, azathioprine > 3 mg/kg/day, or any dose of cyclophosphamide, cyclosporine, or thalidomide;
• Have received leflunomide >20 mg/day in the 6 months prior to Study Day 0;
• Have received fluctuating doses of antimalarials, mycophenolate mofetil, methotrexate,leflunomide, or azathioprine within 28 days before randomization/entry or fluctuating doses of NSAIDs or oral corticosteroids within 14 days before randomization/entry;

  • ALT > 2 × ULN,unless caused by SLE, as determined by the investigator,

  • Platelet count "Platelet count < 50,000/ μL (< 50 × 109/L)"
• History of any disease, evidence of any current disease (other than SLE), any finding upon physical examination, or any laboratory abnormality that, in the opinion of the investigator or medical monitor, may compromise the safety of the patient in the study or confound the analysis of the study; or

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
The safety and tolerability of MEDI-545 will be assessed primarily by summarizing AEs and by assessing changes in viral cultures and titers.	Through Study Day 350.

Secondary Outcome Measures

Outcome Measure	Time Frame
The secondary endpoints of this study are the PK and IM of multiple IV doses of MEDI-545. PK parameters, such as peak concentration.	Study day 350.
