ABSTRACT. Objective. To compare the effects on back pain of teriparatide versus alendronate, we analyzed the reporting of back pain in a head to head comparator trial and a followup study. Methods. In the comparator trial, women were randomized to receive either daily self-injected teriparatide 40 µg plus an oral placebo (n = 73), or daily oral alendronate 10 mg plus self-injected placebo (n = 73). Treatment was for a median 14 months. After completion of the comparator trial, 72% of these patients enrolled in a nontreatment followup study. Adverse events were recorded at each comparator trial visit and followup study visit, and the incidence of new or worsening back pain in each group was compared. Results. During the comparator trial, compared with women randomized to alendronate 10 mg, women randomized to teriparatide 40 µg had reduced risk for any back pain (relative risk 0.27, 95% CI 0.09-0.82) and moderate or severe back pain (relative risk 0.19, 95% CI 0.04-0.86). The differences in the reporting of back pain between the teriparatide treated women and the alendronate treated women were sustained during an interval including the comparator trial plus 18 additional months. During an interval including the comparator trial plus 30 additional months, teriparatide treated patients had numerically fewer occurrences of back pain and moderate or severe back pain. Conclusion. Compared with women randomized to alendronate 10 mg, women randomized to teriparatide 40 µg had reduced risk of back pain during the trial and 2.5 years of followup. (J Rheumatol 2005;32:1556-62

Costimulatory blockade in patients with rheumatoid arthritis: A pilot, dose-finding, double-blind, placebo-controlled clinical trial evaluating CTLA-4Ig and LEA29Y eighty-five days after the first infusion

SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Maintenance of remission following 2 years of standard treatment then dose reduction with abatacept in patients with early rheumatoid arthritis and poor prognosis.

OBJECTIVES: To evaluate maintenance of response while reducing intravenous abatacept dose from ~10 mg/kg to ~5 mg/kg in patients with early rheumatoid arthritis (RA) who achieved disease activity score (DAS)28 (erythrocyte sedimentation rate, ESR) <2.6. METHODS: This 1-year, multinational, randomised, double-blind substudy evaluated the efficacy and safety of ~10 mg/kg and ~5 mg/kg abatacept in patients with early RA with poor prognosis who had reached DAS28 (ESR) <2.6 at year 2 of the AGREE study. The primary outcome was time to disease relapse (defined as additional disease-modifying antirheumatic drugs, ≥2 courses high-dose steroids, return to open-label abatacept ~10 mg/kg, or DAS28 (C reactive protein) ≥3.2 at two consecutive visits). RESULTS: 108 patients were randomised (~10 mg/kg, n=58; ~5 mg/kg, n=50). Three and five patients, respectively, discontinued, and four per group returned to open-label abatacept. Relapse over time and the proportion of patients relapsing were similar in both groups (31% (~10 mg/kg) vs 34% (~5 mg/kg); HR: 0.87 (95% CI 0.45 to 1.69)). Mean steady-state trough serum concentration for the ~10 mg/kg group was 20.3-24.1 µg/mL, compared with 8.8-12.0 µg/mL for the ~5 mg/kg group. CONCLUSIONS: This exploratory study suggests that abatacept dose reduction may be an option in patients with poor prognosis early RA who achieve DAS28 (ESR) <2.6 after ≥1 year on abatacept (~10 mg/kg).
