/ | 投与期において,被験者の多くは女性(150/190例,78.9%)であり,年齢の中央値は56.0歳(範囲:31~74歳)であった。関節リウマチ(RA)の罹患期間の平均値(標準偏差)は7.1(6.85)年であった。約20%の被験者が生物学的製剤の投与を受けていた。このうち,抗TNF製剤の投与歴のある被験者は,43例中27例であった。 | In the Treatment Phase, the majority of subjects were female (150/190 subjects, 78.9%). Median age was 56.0 (range: 31 to 74) years. Overall, the mean (SD) RA duration was 7.1 (6.85) years. Approximately 20% of subjects received prior biologics. Of these, the majority was anti-TNF (27/43 subjects). |
/ | 投与期では194例が無作為化された。無作為化後,194例のうち4例は,投与前に本試験の登録基準を満たさなかったため中止した。190例(プラセボ群54例,100 mg群28例,200 mg群54例,400/200 mg群54例)が少なくとも1回の治験薬の投与を受け,このうち169例(プラセボ群47例,100 mg群26例,200 mg群50例,400/200 mg群46例)が規定された投与期を終了し,21例が投与期中に中止した。投与例(190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169例の被験者は継続投与期に移行した。169例のうち,124例が規定された継続投与期を終了し,45例が継続投与期中に中止した。継続投与期に移行した169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 Treatment Phase, a total of 194 subjects were randomized into the study. After randomization, 4 of 194 subjects discontinued the study before starting study drug treatment due to failing to meet entry criteria. A total of 190 subjects (54 in the placebo group, 28 in the 100 mg group, 54 in the 200 mg group, 54 in the 400/200 mg group) received at least 1 dose of study drug. Of the 190 subjects, 169 subjects (47 in the placebo group, 26 in the 100 mg group, 50 in the 200 mg group, 46 in the 400/200 mg group) completed the planned treatment regimen and 21 discontinued study treatment prematurely during the Treatment Phase. All of the treated subjects (190 subjects) were included in the FAS and Safety Analysis Set. A total of 169 subjects completed the Treatment Phase and entered the Extension Phase. Of the 169 subjects, 124 subjects completed the Extension Phase and 45 subjects discontinued study treatment prematurely during the Extension Phase. All of the subjects who entered the Extension Phase (169 subjects) were included in the FAS and the Safety Analysis Set. |
/ | 投与期において,E6011投与群の有害事象及び副作用の発現率はプラセボ群と比べて高かった(有害事象:プラセボ群63.0%[34/54例],E6011投与群73.5%[100/136例],副作用:プラセボ群22.2%[12/54例],E6011投与群39.7%[54/136例])。用量に依存して有害事象の発現率は高くなったが(プラセボ群63.0%,100 mg群67.9%,200 mg群70.4%,400/200 mg群79.6%),副作用ではその傾向はみられなかった(プラセボ群22.2%,100 mg群46.4%,200 mg群33.3%,400/200 mg群42.6%)。E6011投与群のうち,いずれかの用量群で発現率が5%以上であった有害事象は上咽頭炎,上気道感染,口内炎,気管支炎,背部痛,咽頭炎及び齲歯であった。これらの有害事象のうち,口内炎(プラセボ群1.9%,E6011投与群5.1%),気管支炎(プラセボ群1.9%,E6011投与群4.4%),背部痛(プラセボ群1.9%,E6011投与群4.4%)及び齲歯(プラセボ群0%,E6011投与群2.2%)はE6011群の発現率がプラセボ群と比べて2倍以上高かった。死亡例はみられなかった。E6011投与群において複数の被験者に発現した重篤な有害事象はみられなかった。 継続投与期において,全体169例のうち2例を除くすべての被験者に有害事象がみられた。副作用の発現率は4投与群で同様であった(プラセボ群55.3%[26/47例],100 mg群57.7%[15/26例],200 mg群58.0%[29/50例],400/200 mg群54.3%[25/46例])。全体(169例)で発現率が5%以上であった有害事象は上咽頭炎(59.8%),上気道感染(10.7%),気管支炎,咽頭炎,口内炎及び背部痛(各8.9%),挫傷(7.7%),インフルエンザ(7.1%),胃腸炎(6.5%),悪心及び貧血(各5.9%),帯状疱疹,過角化,注射部位反応,口腔咽頭痛及び鉄欠乏性貧血(各5.3%)であった。 |
In the Treatment Phase, TEAEs and treatment-related TEAEs occurred more frequently in the total E6011 group than the placebo group (TEAEs: 63.0% [34/54 subjects] in the placebo group and 73.5% [100/136 subjects] in the total E6011 group, treatment-related TEAEs: 22.2% [12/54 subjects] in the placebo group and 39.7% [54/136 subjects] in the total E6011 group). A dose response was found in the incidence of TEAEs (63.0% in the placebo group, 67.9% in the 100 mg group, 70.4% in the 200 mg group, 79.6% in the 400/200 mg group), while no apparent dose response was found in the incidence of treatment-related TEAEs (22.2% in the placebo group, 46.4% in the 100 mg group, 33.3% in the 200 mg group, 42.6% in the 400/200 mg group). TEAEs that occurred in >=5% of subjects in any E6011 group were nasopharyngitis, upper respiratory tract infection, stomatitis, bronchitis, back pain, pharyngitis, and dental caries. Among those TEAEs, stomatitis (1.9% in the placebo group, 5.1% in the total E6011 group), bronchitis (1.9% and 4.4%, respectively), back pain (1.9% and 4.4%, respectively), and dental caries (0% and 2.2%, respectively) occurred at twice or more the rate of placebo in the total E6011 group. No deaths were reported. No SAEs occurred in more than 1 subject in the total E6011 group. In the Extension Phase, all but 2 of the 169 subjects in the overall population experienced any TEAE during the study. The incidence of treatment-related TEAEs was similar across the 4 treatment groups (55.3% [26/47 subjects] in the placebo group, 57.7% [15/26 subjects] in the 100 mg group, 58.0% [29/50 subjects] in the 200 mg group, and 54.3% [25/46 subjects] in the 400/200 mg group). TEAEs that occurred in >=5% of the overall population (N=169) were nasopharyngitis (59.8%), upper respiratory tract infection (10.7%), bronchitis, pharyngitis, stomatitis, and back pain (8.9% each), contusion (7.7%), influenza (7.1%), gastroenteritis (6.5%), nausea and anaemia (5.9% each), and herpes zoster, hyperkeratosis, injection site reaction, oropharyngeal pain, and iron deficiency anaemia (5.3% each). |

ACR20 response rate at Week 12 was higher in the 200 mg group and 400/200 mg group than the placebo group; however, a statistically significant difference from placebo was not found (P=0.188 for the 200 mg group, P=0.188 for the 400/200 mg group; a logistic regression model with Hochberg method). |

/ | メトトレキサート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を投与した結果,12週後のACR20反応率は,統計学的に有意な改善は認められなかったが,24週後のACR20反応率は200 mg群及び400/200 mg群で有意な改善が認められた。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。 | In Japanese RA subjects with inadequately responding to MTX, E6011 did not show statistically significant improvement in ACR20 response rate at Week 12 compared with placebo; however, a significant improvement was observed at Week 24 for E6011 200 mg and 400/200 mg. 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. |
