Abstract: OBJECTIVES: To evaluate the effectiveness and safety of transdermal fentanyl (TDF) for the treatment of pain associated with rheumatoid arthritis (RA) or osteoarthritis of the knee or hip (OA), which was not adequately controlled by non-opioid analgesics and/or weak opioids. METHODS: The study design incorporated a 1-week run-in period when current analgesic medications were optimised, a 28-day treatment period and a 1-week taper-off period. Patients with RA (n = 104) and OA (n = 159) started treatment with TDF 25 microg/h. Patches were replaced every 72 h, with the option to up-titrate until adequate pain control was achieved. Metoclopramide was taken during the first treatment week and as needed thereafter. RESULTS: 203 patients completed the treatment phase, 90 entered the taper-off phase. 25 microg/h was the most frequently used maximum dose (51%). Pain control was increased from 4% to 29% of patients during run-in. The number of patients reaching adequate pain control in the first treatment week was increased to 75%, and increased further to 88% on day 28 and to 80% at endpoint. From baseline (screening) to endpoint, there were significant reductions in pain (p < 0.001) on the Wisconsin Brief Pain Inventory, and significant improvements in quality of life (Short-Form-36: physical p < 0.001; mental health p < 0.05). Eighty per cent of the patients (n = 134) assessed the treatment favourably; nausea and vomiting were the most common adverse events, mainly occurring at treatment initiation. Efficacy of metoclopramide appeared limited. TDF could be initiated in patients pre-treated with non-opioid analgesics or weak opioids and tapered off without major complications. CONCLUSIONS: TDF significantly improved pain control and quality of life, and was well tolerated in patients with RA or knee/hip OA who continued to experience pain on their current analgesic treatment. Treatment could be discontinued without issues. Nausea and vomiting was usually mild during treatment initiation. Patients' well being could be further accommodated by optimising prophylactic treatment.

Abstract: This study evaluated transdermal fentanyl (TDF) for the treatment of pain from rheumatoid arthritis (RA) which was not adequately controlled by nonopioid analgesics and/or weak opioids. Following 1 week of optimization of current analgesic medication, patients (n = 104) started 28-day treatment with 25 microg/h of TDF, with the option to up-titrate until adequate pain control was achieved. Metoclopramide was taken during the 1st week and as needed thereafter. Eighty-four patients completed the treatment phase, and 42 entered the 1-week tapering-off phase. The most frequently used maximum dose was 25 microg/h. The number of patients with pain control increased, particularly in the 1st week of treatment (33% to 77%), to 88% on day 28. From baseline to endpoint, there were reductions in pain (P < 0.001), including in "pain right now" at 24 h, and in degree of pain (mean reduction from "severe" to "moderate"), improvements in function (majority of items in the Health Assessment Questionnaire) (P < 0.001), and in quality of life (Short Form 36 physical P < 0.001, mental P < 0.05). Treatment was assessed favorably: > or = 78% would recommend it. Transdermal fentanyl should be considered in treatment programs for patients with RA.

Abstract: OBJECTIVE: To compare the clinical efficacy and safety of leflunomide and methotrexate for the treatment of rheumatoid arthritis (RA). METHODS: In this multicentre, double-blind trial, 999 subjects with active RA were randomized to leflunomide (n = 501; loading dose 100 mg/day for 3 days, maintenance dose 20 mg/day) or methotrexate (n = 498; 10-15 mg/week) for 52 weeks. After 1 yr the subjects could choose to stay for a second year of double-blind treatment. The primary end-points were tender and swollen joint counts and overall physician and patient assessments. Analyses were of the intent-to-treat group. RESULTS: After 1 yr, the mean changes in the leflunomide and methotrexate groups, respectively, were -8.3 and -9.7 for tender joint count; -6.8 and -9.0 for swollen joint count; -0.9 and -1.2 for physician global assessment; -0.9 and -1.2 for patient global assessment; -14.4 and -28.2 for erythrocyte sedimentation rate. Improvements seen with methotrexate were significantly greater than those with leflunomide. No further improvement occurred after the second year of treatment and the distinction between the two treatments in terms of tender joint count and patient global assessment was lost. During the first year of treatment, a small and equivalent degree of radiographically assessed disease progression was seen with both drugs. After 2 yr, disease progression was significantly less with methotrexate. The most common treatment-related adverse events in both groups were diarrhoea, nausea, alopecia, rash, headache, and elevated plasma liver enzyme levels. Over 2 yr, 21 subjects receiving methotrexate were withdrawn due to elevated plasma liver enzymes vs eight subjects taking leflunomide. Two drug-related deaths from pulmonary causes were recorded with methotrexate vs no drug-related deaths among the subjects receiving leflunomide. CONCLUSIONS: Both leflunomide and methotrexate are efficacious for prolonged treatment of RA. At the doses used, some clinical benefit of methotrexate over leflunomide was observed in the first year of treatment. This benefit must be weighed against the potential toxicity of this drug when used without folate supplementation.

Abstract: OBJECTIVES: Everolimus, a proliferation signal inhibitor with disease-modifying properties, may be useful in treating rheumatoid arthritis (RA). This proof-of-concept study assessed efficacy and safety of everolimus in combination with methotrexate (MTX) in patients with refractory RA. METHODS: A multi-centre, randomised, double-blind, placebo-controlled trial was performed in 121 patients with active RA receiving MTX. Patients were randomised to receive everolimus (6 mg/day) or placebo. The primary endpoint was the American College of Rheumatology criteria for a 20% improvement in measures of disease activity (ACR20) at 12 weeks. RESULTS: There was a rapid onset of action and at 12 weeks the ACR20 response rate was significantly higher in the everolimus group (36.1%) than in the placebo group (16.7%; p = 0.022). Improvements from baseline in tender and swollen joint counts, patient's assessment of pain, and patient's and physician's global assessment of disease activity were significantly greater after treatment with everolimus. The most common adverse events (AEs) in the everolimus group were gastrointestinal (52.5% vs 31.7% in the placebo group), skin (29.5% vs 8.3%), and nervous system disorders (21.3% vs 10.0%); AEs leading to treatment discontinuation were reported for 16.4% and 10.0% of patients, respectively. Changes in haematological parameters, liver function tests, and lipid levels occurred more frequently with everolimus compared to placebo, but were mild and reversible. CONCLUSIONS: The study indicates that everolimus plus MTX provides clinical benefit with an acceptable safety and tolerability profile. It may offer a new treatment option in RA patients with inadequate response to MTX.
