Also, while 20% improvement in symptoms is the least expensive level acceptable to a clinician to indicate efficacy, an individual patient may consider a different level of improvement acceptable to continue that therapy. 256, and with 4.5?years of golimumab, overall intent-to-treat Assessment in SpondyloArthritis international Society criteria for 20% improvement (ASAS20) and ASAS40 response rates were 66.0% (235/356) and 57.0% (203/356), respectively; Bath AS Disease Activity Index 50% improvement response was 55.9% (199/356). Observed response rates among the 255 (72%) patients who continued golimumab through week 252 were consistent, albeit somewhat higher. Among patients who increased golimumab from 50 to 100?mg, 60.6% (20/33) Rabbit Polyclonal to TBX18 and 44.7% (17/38) achieved ASAS20/ASAS40 responses, respectively, following 2 consecutive doses of golimumab 100?mg. Golimumab security through week 268 was comparable to that through week 24 regardless of dose. Conclusions Clinical improvements observed in patients treated with golimumab through week 24 were sustained through week 256 (5?years). Long-term golimumab security is consistent with that of other established tumour-necrosis-factor-antagonists. Trial registration number ClinicalTrials.gov: “type”:”clinical-trial”,”attrs”:”text”:”NCT00265083″,”term_id”:”NCT00265083″NCT00265083. Golimumab, a human monoclonal antibody to tumour necrosis factor (TNF)- that is administered subcutaneously every 4?weeks, is approved for treating active ankylosing spondylitis (AS). We previously reported results of the double-blind, randomised, placebo-controlled, Phase 3 GO-RAISE study, in which golimumab was evaluated in patients with active AS, through week 241 and week 1042 and now statement findings through the completion of the 5-12 months GO-RAISE trial. Patients and methods Details of GO-RAISE patient eligibility criteria and study design have been reported1 and are summarised in the online supplement. Details of Gboxin analyses specific to this 5-12 months statement are also provided in the online product.3C12 Results Patient disposition/characteristics and concomitant medications Among the 356 randomised patients, 355 received study treatment (physique 1). Baseline individual and disease characteristics,1 as well as individual disposition through week 241 and week 104,2 have been reported. Open in a separate window Physique?1 Patient disposition through week 268. At week 16, 41 of 78 (52.6%) and 25 of Gboxin 137 (18.2%) patients in Groups 1 and 2, respectively, had 20% improvement in total back pain and morning stiffness and entered early escape. Among the 355 treated patients, 101 (28.5%) discontinued study agent through week 252 (figure 1). Among patients who discontinued study agent due to adverse events (AEs), being lost to follow-up, or due to other reasons, 51% achieved an Assessment in SpondyloArthritis international Society criteria for 20% improvement (ASAS20) response at the visit preceding discontinuation, versus 15% of patients who discontinued due to unsatisfactory therapeutic effect. The proportion of patients using non-steroidal anti-inflammatory drugs declined from baseline to week 268 from 90% to 74% while that using disease-modifying antirheumatic drugs was relatively stable (32% to 36%) during the study. Efficacy Assessment in SpondyloArthritis international Society (ASAS) responses Results of intent-to-treat (ITT) analyses indicated that 220/356 (61.8%) and 166/356 (46.6%) patients achieved ASAS20 response and/or 40% improvement (ASAS40) improvement, respectively, at week 24. At week 256, 235/356 (66.0%; 95% CI 61.1% to 70.9%) and 203/356 (57.0%; 95% CI 51.9% to 62.1%) patients achieved ASAS20 and/or ASAS40 response, respectively (physique 2A, B). ASAS partial remission (value 2 in each ASAS domain name) was achieved by 121/356 (34.0%; 95% CI 29.1% to 38.9%) patients treated with golimumab at week 256 (figure 2C). Response rates were consistent, albeit somewhat higher, when assessed using observed data among patients who did not discontinue study participation by week 24 (observe online supplementary physique S1ACC). Open in a separate window Physique?2 The proportions of patients in ASAS20 response (A), ASAS40 response (B), and/or ASAS partial remission (C) through week 256 based on intent-to-treat analyses. The placebo-controlled study period ended at week 24, but study participants and investigators remained blinded to the golimumab dose (50 mg or 100?mg) through week 100. During the long-term extension, which started with the week-104 golimumab injection, the investigator could increase or decrease the golimumab dose. ASAS20/40, 20%/40% improvement in the Assessment of SpondyloArthritis international Society (ASAS) criteria. Based on observed data, 54 patients escalated the golimumab dose from 50?mg to 100?mg during the trial. While 21 (38.9%) Gboxin and 16 (29.6%) of these patients, respectively, achieved an ASAS20 or ASAS40 response before dose escalation, 33 and 38 patients, respectively, had not. Among these latter patients, 60.6% (20/33) achieved ASAS20 and 44.7% (17/38) achieved ASAS40 responses following 2 consecutive doses of golimumab 100?mg. Additional clinical findings are reported in the online supplement. Health-related quality of life (HRQoL) Mean changes from baseline in the physical component summary and mental component summary scores of the 36-item Short Form health survey indicated improvements in patients HRQoL were sustained with up to 5?years of golimumab treatment (see online supplementary table S1). When assessed using ITT analyses, 93/356 (26.1%; 95% CI 21.5% to 30.7%) and 180/356 (50.6%; 95% CI 45.4% to 55.8%) had achieved 36-item Short Gboxin Form health survey physical component summary and mental component summary scores 50, respectively, at week 256 (see online supplementary table S1).
