Safety and Effectiveness of Two Doses of ABT-874 as Compared to Placebo in Subjects With Multiple Sclerosis (MS)

2. januar 2013 opdateret af: AbbVie (prior sponsor, Abbott)

A 24-Week, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled, Dose Finding, Safety, Tolerability, and Efficacy Study of the Human Anti-IL-12 Antibody ABT-874 in Subjects With Multiple Sclerosis With a 24-Week Double-Blind, Active Extension Phase

The objective of the trial is to study the safety and effectiveness of ABT-874 administered weekly or every other week in patients with relapsing remitting and secondary progressive multiple sclerosis as compared to placebo. Effectiveness will be measured based on MRI scans done periodically throughout the study.

    • Disease associated with an increased risk of malignancy (such as familial polyposis).
  • History of major immunologic reaction (such as serum sickness or anaphylactoid reaction) to an Immunoglobulin G (IgG) containing agent (such as intravenous (IV) gamma globulin, a fusion protein, or monoclonal antibody)
  • Confounders of the assessment of neurologic response including other diseases that produce chronic neurologic manifestations (such as amyotrophic lateral sclerosis, Guillain-Barre syndrome, Lyme disease, myasthenia gravis, etc.)
  • Prior exposure to anti-IL-12 antibodies
  • Confounders of safety assessment, such as an unstable medical condition not related to MS (including those requiring an adjustment of treatment in the four weeks prior to Screening)
  • Exacerbation of asthma requiring hospitalization in the ten years prior to Screening (subjects with asthma not requiring hospitalization should be discussed with the medical monitor prior to Screening)
  • Pregnant or lactating females
  • The following exclusionary laboratory values at screening or baseline:

    • Hemoglobin (Hgb) <10 g/dL in females or <12 g/dL in males;
    • White blood cell (WBC) count <3 x 109/L;
    • Platelet count <100 x 109/L
    • Serum aspartate transaminase (AST) or alanine transaminase (ALT) x 3 upper limits of normal (ULN);
    • Serum total bilirubin >/= 3 mg/dL (>/= 51 x mol/L)
    • Serum creatinine >1.6 mg/dL (> 141 x mol/L)
  • Subject has a recent history of substance abuse or psychiatric illness that could preclude compliance with the protocol
  • In the eight weeks prior to study drug administration, the subject has received a transfusion of any blood product, or has had 500 mL or more of blood removed by repetitive or one-time blood donation, plasmapheresis, or plasma exchange, or has lost 550 mL or more blood because of hemorrhage; or
  • For any reason, subject is considered by the investigator to be an unsuitable candidate to receive ABT-874.
