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

2 de enero de 2013 actualizado por: 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.

Descripción general del estudio

Descripción detallada

This study was done in subjects with relapsing remitting MS or secondary progressive MS with the objective of assessing the safety and efficacy of 200 mg of ABT-874 weekly or QOW versus placebo. There were 3 phases to the study, 24 week double blind followed by 24 weeks of an active extension, followed by 48 weeks of double blind active extension. The trial was discontinued by Abbott in Aug 2006.

    • 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.
