To assess long-term efficacy & safety of golimumab (GLM) in active PsA.
PsA pts with >=3 swollen and >=3 tender joints and psoriasis were randomized to SC PBO or GLM (50 or 100 mg) q4wks. At wk 16, pts with inadequate arthritis response entered early escape (EE). All pts received GLM from wk 24. Investigators could dose-escalate pts receiving GLM 50 mg to 100 mg based on clinical judgement after all pts reached wk 52. The results for pts who remained on the same dose of GLM 50 to 100 mg are described. Analyses were based on observed data.
405 pts with active PsA were randomized (113 PBO, 146 GLM 50 mg, 146 GLM 100 mg). GLM was significantly better than PBO in improving signs and symptoms of PsA at wk 24, and GLM efficacy was maintained through wk 52.Through wk 104, pts continuing on the same dose of GLM 50 or 100 mg maintained high levels of response. GLM 50 mg pts who switched to 100 mg in EE or via dose escalation also achieved clinically meaningful responses (Table). 8.6% (34/394) of GLM-treated pts experienced SAEs through wk 104. Injection site reactions occurred in 8.9% (35/394) of pts. There was 1 case of histoplasmosis in a pt (GLM 100 mg) that was successfully treated. Malignancies reported through wk 104 include basal cell skin (1 pt), colon (1 pt), and small cell lung cancer (1 pt) in pts receiving GLM 50 mg, and basal cell skin (3 pts), prostate (1 pt), and small cell lung cancer (1 pt; fatal) in pts receiving GLM 100 mg. An additional pt died due to a climbing accident (GLM 50 mg).
Table. Summary of efficacy in GO-REVEAL through wk 104
Pts with active PsA treated with GLM 50 and 100mg SC q4 wks maintained high levels of improvement through wk 104. GLM was generally well-tolerated, with a safety profile similar to that observed for other anti-TNF agents.
