Efficacy and safety of golimumab in patients with ankylosing spondylitis: results of a randomized, double-blind, placebo-controlled, phase III trial.

Abstract: Objective To evaluate the efficacy and safety of golimumab in patients with ankylosing spondylitis (AS) in the GO-RAISE study. Methods Patients with active AS, a Bath AS Disease Activity Index (BASDAI) score > or =4, and a back pain score of > or =4 were randomly assigned in a 1.8:1.8:1 ratio to receive subcutaneous injections of golimumab (50 mg or 100 mg) or placebo every 4 weeks. The primary end point was the proportion of patients with at least 20% improvement in the ASsessment in AS (ASAS20) criteria at week 14. Results At randomization, 138, 140, and 78 patients were assigned to the 50-mg, 100-mg, and placebo groups, respectively. After 14 weeks, 59.4%, 60.0%, and 21.8% of patients, respectively, were ASAS20 responders (P or =1 adverse event, and 5.4% and 6.5% of patients, respectively, had > or =1 serious adverse event. Eight golimumab-treated patients and 1 placebo-treated patient had markedly abnormal liver enzyme values (> or =100% increase from baseline and a value >150 IU/liter), which were transient. Conclusion Golimumab was effective and well tolerated in a large cohort of patients with AS during a 24-week study period.

Robustly estimating the flow direction of information in complex physical systems.

Abstract: We propose a new measure (phase-slope index) to estimate the direction of information flux in multivariate time series. This measure (a) is insensitive to mixtures of independent sources, (b) gives meaningful results even if the phase spectrum is not linear, and (c) properly weights contributions from different frequencies. These properties are shown in extended simulations and contrasted to Granger causality which yields highly significant false detections for mixtures of independent sources. An application to electroencephalography data (eyes-closed condition) reveals a clear front-to-back information flow.
