NCT02776774
There is considerable interest in using in-wound antibiotics (IWA) to prevent infection after spine surgery. An adequate evaluation of IWA is lacking and prior studies are limited by confounding and bias. This prospective study will enroll spine surgeons across the country to complete a survey about their knowledge, attitudes, and practices for using in-wound antibiotics.
NCT00476996
This study will evaluate the efficacy and safety of ocrelizumab, compared with placebo, in patients with active rheumatoid arthritis who have an inadequate response to at least one anti-TNF-alpha therapy. Patients will be randomized to receive placebo, 200mg of intravenous ocrelizumab, or 500mg of i.v. ocrelizumab on days 1 and 15. A repeat course of i.v. treatment will be administered at weeks 24 and 26. All patients will receive stable doses of either concomitant methotrexate (7.5-25mg/week) or leflunomide (10-20mg po daily) and may receive additional DMARDs. The treatment period is planned for 48 weeks (until primary analysis) and then participants will enter the open label phase until the drug is commercialized. Target sample size is 1000.
