SAT0270 5 Year Safety, Efficacy, and Radiographic Data in Patients with Active Psoriatic Arthritis Treated with Golimumab: Long-Term Extension Results of the Randomized, Placebo-Controlled Study Go-Reveal

Objectives Safety, efficacy, & radiographic progression in GLM-treated pts from long-term extension of GO-REVEAL is presented. Methods 405 PsA pts (≥3 SJ, ≥3 TJ counts) were rand to SC PBO (Grp1, n=113), GLM50mg (Grp2, n=146), or GLM100mg (Grp3, n=146) q4wks thru wk20. Concomitant MTX at baseline (BL) was allowed but not required. At wk16, pts with Results Of 405 pts rand, 335 cont’d in the study at wk104, & 279 pts (69%) cont’d GLM thru wk252. 29% of Grp2 pts dose escalated to GLM100mg; 25% of Grp3 pts decreased dose from 100mg to 50mg. BL characteristics of pts who cont’d in the study at wk104 & efficacy at wk256 are provided(Table). ACRP changes from BL in SHS scores were minimal&numerically less in pts tx with GLM & MTXvs GLM alone. 88%, & 21% GLM-tx pts experienced AE & SAE, resp. 12% of pts d/c GLM due to AE, & 5% & 4% pts experienced malignancy (incl NMSC),& serious infection, resp. Antibodies to GLM were detected in 6% of pts. Conclusions Pt attrition thru 5yrs of GLM tx was low. GLM tx resulted in long-term maintenance of clinically meaningful responses in arthritic & skin components of PsA, improved physical function, & arrest of radiographic progression. No apparent differences between long-term safety&efficacy of 2 GLM doses administered q4wks were observed, however, interpretation of the data is limited due to tx changes allowed across rand grps.
