旨在评估早期类风湿性关节炎(RA)患者皮下注射阿巴西普加甲氨蝶呤(MTX)和阿巴西普单药治疗 12 个月时的临床缓解情况,以及快速撤除所有 RA 治疗后缓解情况的维持情况。在评估极早期类风湿性关节炎治疗 3b 期试验中,早期活动性 RA 患者被随机分为双盲、每周皮下注射阿巴西普 125 mg 加 MTX、阿巴西普 125 mg 单药治疗或 MTX,疗程为 12 个月。第 12 个月时疾病活动度较低(疾病活动评分 (DAS)28(C 反应蛋白 (CRP))<3.2)的患者进入了所有 RA 治疗的 12 个月停药期。共同主要终点是阿巴西普联合 MTX 与 MTX 在第 12 个月以及第 12 个月和第 18 个月时 DAS28 (CRP) <2.6 的患者比例。患者有 RA 症状 <2  年,DAS28 (CRP) ≥3.2,抗瓜氨酸肽-2 抗体阳性,95.2% 为类风湿因子阳性。对于阿巴西普联合 MTX 与 MTX 相比,12 个月时 DAS28 (CRP) <2.6 的比例分别为 60.9% 和 45.2% (p=0.010),停药后,12 个月和 18 个月时分别为 14.8% 和 7.8% (p=0.045)。阿巴西普单药治疗的 DAS28 (CRP) <2.6 的比例为 42.5%(第 12 个月)和 12.4%(第 12 个月和第 18 个月)。两个阿巴西普组的安全性与单独使用 MTX 相当。与单独使用 MTX 相比,阿巴西普联合 MTX 在早期 RA 中表现出强大的疗效,并具有良好的安全性。停止所有 RA 治疗后获得持续缓解表明阿巴西普的机制对自身免疫过程有影响。 NCT01142726。
To evaluate clinical remission with subcutaneous abatacept plus methotrexate (MTX) and abatacept monotherapy at 12 months in patients with early rheumatoid arthritis (RA), and maintenance of remission following the rapid withdrawal of all RA treatment. In the Assessing Very Early Rheumatoid arthritis Treatment phase 3b trial, patients with early active RA were randomised to double-blind, weekly, subcutaneous abatacept 125 mg plus MTX, abatacept 125 mg monotherapy, or MTX for 12 months. Patients with low disease activity (Disease Activity Score (DAS)28 (C reactive protein (CRP)) <3.2) at month 12 entered a 12-month period of withdrawal of all RA therapy. The coprimary endpoints were the proportion of patients with DAS28 (CRP) <2.6 at month 12 and both months 12 and 18, for abatacept plus MTX versus MTX. Patients had <2 years of RA symptoms, DAS28 (CRP) ≥3.2, anticitrullinated peptide-2 antibody positivity and 95.2% were rheumatoid factor positive. For abatacept plus MTX versus MTX, DAS28 (CRP) <2.6 was achieved in 60.9% versus 45.2% (p=0.010) at 12 months, and following treatment withdrawal, in 14.8% versus 7.8% (p=0.045) at both 12 and 18 months. DAS28 (CRP) <2.6 was achieved for abatacept monotherapy in 42.5% (month 12) and 12.4% (both months 12 and 18). Both abatacept arms had a safety profile comparable with MTX alone. Abatacept plus MTX demonstrated robust efficacy compared with MTX alone in early RA, with a good safety profile. The achievement of sustained remission following withdrawal of all RA therapy suggests an effect of abatacept's mechanism on autoimmune processes. NCT01142726.
