Adalimumab Added to Methotrexate andIntra-Articular Glucocorticoid Increases Remission Rates At One Year In Early,DMARD-Naïve Patients with Rheumatoid Arthritis - An Investigator-Initiated Randomized, Controlled, Double-Blinded Study Hørslev-Petersen K, et al: Presented at ACR 2011; Poster #394
Adalimumab + Methotrexate & Intra-articular Glucocorticoid in DMARD-naïve, Early RA • Objective: To assess the efficacy and safety of adding adalimumab (ADA) to methotrexate (MTX) and intra-articular glucocorticoid • Subjects: 180 DMARD-naïve RA patients, disease duration < 6 months • Methodology: • Subjects were randomized to MTX 7.5 mg weekly + ADA 40 mg every other week or MTX + placebo • All patients had triamcinolone injections into swollen joints at weeks 0, 4, 8, and 12, then every third month up to 12 months • If DAS28 > 3.2 at 3 months, sulfasalazine & hydroxychloroquine were added • Assessments: DAS28 (CRP), SDAI and ACR/EULAR remission criteria • Primary outcome: Frequency of DAS28 (CRP) < 3.2 Adapted from Hørslev-Petersen K, et al: Presented at ACR 2011; Poster #394

Adalimumab + Methotrexate & Intra-articularGlucocorticoid in DMARD-naïve, Early RA: Conclusions • In DMARD-naïve patients with early RA, excellent disease control was achieved by a targeted step-up strategy using methotrexate and intra-articular glucocorticoid injections • Addition of adalimumab to methotrexate and intra-articular glucocorticoid improved the remission rates considerably • The treatments were well tolerated Adapted from Hørslev-Petersen K, et al: Presented at ACR 2011; Poster #394
Adalimumab + Methotrexate & Intra-articular Glucocorticoid in DMARD-naïve, Early RA Commentary from International Literature Search in Rheumatology’s Canadian Editorial Panel • This study used methotrexate doses of 20 mg per week, which reflects current practice in Canada; the use of intra-articular injections also applies to rheumatology standard-of-care in Canada • This study is, therefore, very applicable in our context • The only issue is availability of biologics in very early disease, but this study helps to corroborate the need for early treatment with biologics in RA Commentary on Hørslev-Petersen K, et al: Presented at ACR 2011; Poster #394

Phase II Study of Secukinumab in Rheumatoid Arthritis: Conclusions • The primary efficacy endpoint was not achieved in this trial • ACR20 responders at Week 16 experienced maintenance or improvement of efficacy through week 52 with highest efficacy in patients who remained on secukinumab 150 mg throughout the trial • DAS28 and HAQ scores improved through week 52 in responders who remained on secukinumab 150 mg • Patients on secukinumab who were non-responders at week 18 did not gain much additional efficacy benefit through week 52 after dose escalation • Infection was the most frequently reported adverse event, with nasopharyngitis and pharyngitis reported most commonly • The rate of adverse events, including infections, was not dose dependent Adapted from Genovese MC, et al: Presented at ACR 2011; Poster #401
Phase II Study of Secukinumab in Rheumatoid Arthritis Commentary from International Literature Search in Rheumatology’s Canadian Editorial Panel • The success of biologic agents for the treatment of RA over the past 10 years has generated ongoing research to find drugs that target new pathways • A Phase 2 study previously reported that targeting IL-17 with secukinumab did not achieve its primary endpoint at week 16 • This paper reports further data up to 1 year from that study and shows that although the group that did respond maintained their response, those who were non-responders did not improve with dose escalation • As reported elsewhere at this meeting, there are positive data treating spondyloarthropathies with this agent, particularly ankylosing spondylitis, but it remains to be seen whether targeting IL-17 will turn out to be a useful addition to treat RA Commentary on Genovese MC, et al: Presented at ACR 2011; Poster #401

Subcutaneous vs. Intravenous Abatacept in RA: Long-term Results Commentary from International Literature Search in Rheumatology’s Canadian Editorial Panel • In this trial, patients with relatively longstanding RA (8 years) did well on either i.v. or s.c. abatacept, with similar retention, efficacy and safety in both groups • It remains to be seen whether patients who are currently receiving i.v .abatacept monthly will be interested in switching to weekly s.c. dosing, but this study does provide reassurance that, for those who wish to make the switch, the medication is effective Commentary on Genovese MC, et al: Presented at ACR 2011; Poster #402
