The majority of subjects were female (50/64 subjects, 78.1%). Overall, the mean (SD) RA duration was 9.2 (6.26) years. A total of 65.6% of subjects received 1 prior biologic with inadequate response and 34.4% of subjects received 2 prior biologics. The majority of prior biologics was anti-TNF (67.2%, 43/64 subjects). The mean (SD) dose of MTX was 9.4 (2.86) mg/week. |
/ | 投与期では66例が無作為化された。無作為化後,66例のうち2例は,投与前に中止した。64例(プラセボ群33例,E6011投与群31例)が少なくとも1回の治験薬(E6011 400 mg又はプラセボ)の投与を受け,このうち55例(プラセボ群29例,E6011 400 mg群26例)が規定された投与期(0週から12週)を終了し,9例が投与期(0週から12週)中に中止した。投与例(64例)のすべての被験者はFAS及び安全性解析集団に採用された。投与期を終了した55例の被験者は,12週の時点で再割り付けされ(E6011 200 mg又は400 mgを投与),継続投与期に移行した(プラセボ/200 mg群15例,プラセボ/400 mg群14例,400/200 mg群14例,400/400 mg群12例)。再割り付けされた55例のうち,48例が規定された投与期(12週から24週)を終了し,7例が投与期(12週から24週)中に中止した。47例が投与期を終了し,継続投与期に移行した。このうち,21例が継続投与期を終了し,26例が継続投与期中に中止した。継続投与期に移行した47例のすべての被験者はFAS及び安全性解析集団に採用された。 | In the Treatmemnt Phase, a total of 66 subjects were randomized into the study. After randomization, 2 of 66 subjects discontinued the study before starting study drug treatment. A total of 64 subjects (33 in the placebo group and 31 in the E6011 group) received at least 1 dose of study drug (E6011 400 mg or placebo). Of the 64 subjects, 55 subjects (29 in the placebo group, 26 in the 400 mg group) completed the planned treatment regimen and 9 discontinued study treatment prematurely during the Core Treatment Phase (Weeks 0-12). All of the treated subjects (64 subjects) were included in the FAS and Safety Analysis Set. Fifty-five subjects were re-randomized at Week 12 and treated with E6011 200 mg or 400 mg (15 subjects for placebo/200 mg, 14 subjects for placebo/400 mg, 14 subjects for 400/200 mg, 12 subjects for 400/400 mg). Of the 55 subjects re-randomized, 48 completed the planned treatment regimen and 7 discontinued study treatment prematurely between Week 12 and Week 24. In the Extension Phase, a total of 47 subjects completed the Treatment Phase and were rolled over in the Extension Phase. Of the 47 subjects, 21 subjects completed the Extension Phase and 26 subjects discontinued study treatment prematurely during the Extension Phase. All of the subjects who were rolled over in the Extension Phase (47 subjects) were included in the FAS and the Safety Analysis Set. |

During the Core Treatment Phase, the incidence of TEAEs was 57.6% (19/33 subjects) in the placebo group and 45.2% (14/31 subjects) in the E6011 group. The incidence of treatment-related TEAEs was 27.3% (9/33 subjects) in the placebo group and 25.8% (8/31 subjects) in the E6011 group. TEAEs that occurred in at least 2 subjects in the E6011 group were stomatitis, injection site erythema, nasopharyngitis, and blood creatine phosphokinase increased. Among those TEAEs, stomatitis (0% in the placebo group, 6.5% in the E6011 group), injection site erythema (0% in the placebo group, 6.5% in the E6011 group), blood creatine phosphokinase increased (0% in the placebo group, 6.5% in the E6011 group) occurred more frequently in the E6011 group than the placebo group. During the Entire Treatment Phase, the incidence of TEAEs was 80.0% (12/15 subjects) in the placebo/200 mg group, 92.9% (13/14 subjects) in the placebo/400 mg group, 92.9% (13/14 subjects) in the 400/200 mg group and 75.0% (9/12 subjects) in the 400/400 mg group. The incidence of treatment-related TEAEs was 46.7% (7/15 subjects) in the placebo/200 mg group, 42.9% (6/14 subjects) in the placebo/400 mg group, 42.9% (6/14 subjects) in the 400/200 mg group, and 33.3% (4/12 subjects) in the 400/400 mg group. TEAEs that occurred in at least 2 subjects in the 400/200 mg group or 400/400 mg group were injection site erythema and nasopharyngitis. Two of 14 subjects (14.3%) experienced injection site erythema in the 400/200 mg group while no subjects experienced it in the 400/400 mg group. The incidence of nasopharyngitis was similar between the 400/200 mg group and 400/400 mg group (28.6% in the 400/200 mg group, 33.3% in the 400/400 mg group). In the Extension Phase, TEAEs that occurred in at least 10% of subjects in the overall population were nasopharyngitis (51.1%, 24/47 subjects), and gastroenteritis, rash, back pain, anaemia, and hepatic function abnormal (10.6% each, 5/47 subjects). |
/ | 12週後のACR20反応率は,プラセボ群が27.3%(9/33例),E6011投与群が22.6%(7/31例)であった。E6011投与群のACR20反応率のプラセボ群との差では,統計学的な有意差は認められなかった(P=0.621,ロジスティック回帰分析)。 | ACR20 response rate at Week 12 was 27.3% (9/33 subjects) in the placebo group and 22.6% (7/31 subjects) in the E6011 group.

/ | 生物学的製剤による治療で効果不十分な日本人関節リウマチ患者を対象にE6011 400 mgを投与した結果,12週後のACR20反応率はプラセボ群に比べ,十分な有効性が示されなかった。また,E6011を200 mgから400 mgの用量で102週まで2週ごとに皮下投与したところ,全般的に安全で忍容性が良好であった。 | E6011 400 mg did not show clear efficacy in ACR20 response rate at Week 12 compared with placebo in Japanese RA subjects with inadequately responding to biologics. E6011 was well tolerated with no notable safety concerns at doses of 200 to 400 mg when administered subcutaneously every 2 weeks for up to 102 weeks. |
