Abstract

To determine the safety of an antisense oligodeoxynucleotide to intercellular adhesion molecule-1 (ICAM-1) (ISIS 2302), administered in an intensive 4 week regimen with dose escalation; and to provide preliminary evidence for efficacy in rheumatoid arthritis (RA). Patients with active RA were enrolled in a 6 month, double blind, placebo controlled, dual center, dose escalation (0.5, 1, and 2 mg/kg) study. Subjects received a total of 13 intravenous ISIS 2302 infusions, given on alternate days for 2 weeks and then 3 times a week for another 2 weeks. Doses of corticosteroids (< or = 10 mg/day) and disease modifying antirheumatic drugs (stable > or = 3 months) remained constant throughout the study. The primary efficacy endpoint was the Day 26 Paulus index, with secondary evaluations at Months 2-6. A total of 43 patients were enrolled with 11, 10, 3, and 19 patients receiving placebo or 0.5, 1, or 2 mg/kg of ISIS 2302, respectively. There were no differences between groups after randomization and the mean baseline swollen joint count was 22.5. Pharmacokinetic studies revealed a T(1/2) of 63 min and first-order kinetics with slight dose dependency, suggesting a saturable clearance process, although no accumulation was noted with re...Continue Reading
