Brief summary

The objective of this study was to verify the efficacy of ASP015K versus placebo administrated in combination with methotrexate (MTX) over placebo in terms of efficacy in participants with rheumatoid arthritis (RA) who had an inadequate response to MTX

Detailed description

This study was a multi-center, randomized, placebo-controlled, double-blind, parallel-group, confirmatory study to evaluate the efficacy and safety of ASP015K (100 and 150 mg/day) administered in combination with MTX in participants with RA who had an inadequate response to MTX. Participants orally received ASP015K 100 mg, ASP015K 150 mg or placebo once daily (QD) in combination with MTX after breakfast for 52 weeks. At Week 12, inadequate responders in the placebo group, as determined by a \< 20% improvement from baseline (i.e., treatment initiation day) in tender or painful joint count (TJC) and swollen joint count (SJC), were switched to either ASP015K 100 mg or ASP015K 150 mg, and the dosage was maintained until the end of treatment (EOT). In addition, participants who received placebo at Week 28 were switched to either ASP015K 100 mg or ASP015K 150 mg, and the dosage was maintained until the EOT. The ASP015K dose that was started for placebo group participants at Week 12 or Week 28 was randomly chosen at baseline. The dose was switched under the blinded condition. Participants who completed this study were eligible for participation in the open-label extension study (015K-CL-RAJ2). Participants made a follow-up visit after the week 52 visit if they did not enroll into the extension study on the day of the week 52 visit.

Change From Baseline in mTSS at Week 28Baseline and week 28/ETmTSS was defined as the sum of joint erosion scores graded by assessing erosion severity in 44 joints (16 per hand and 6 per feet) and JSN scores graded by assessing narrowing of joint spaces in 42 joints (15 per hand and 6 per feet). Erosion score was scored from 0 (no erosion) to 5 (complete collapse of bone) and the score for erosion ranges from 0 to 160 in the hands and from 0 to 120 in the feet (the maximum erosion score for a joint in the foot is 10). JSN including subluxation, was scored from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation), with a maximum JSN score of 168. mTSS scores ranged from 0 (normal) to 448 (worst possible total score). Change from baseline was calculated as score at week 28 (ET) minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

Change From Baseline in mTSS at Week 52Baseline and week 52/ETmTSS was defined as the sum of joint erosion scores graded by assessing erosion severity in 44 joints (16 per hand and 6 per feet) and JSN scores graded by assessing narrowing of joint spaces in 42 joints (15 per hand and 6 per feet). Erosion score was scored from 0 (no erosion) to 5 (complete collapse of bone) and the score for erosion ranges from 0 to 160 in the hands and from 0 to 120 in the feet (the maximum erosion score for a joint in the foot is 10). JSN including subluxation, was scored from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation), with a maximum JSN score of 168. mTSS scores ranged from 0 (normal) to 448 (worst possible total score). Change from baseline was calculated as score at week 52 (ET) minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.
Change From Baseline in JSN Score at Week 28 and Week 52Baseline and weeks 28/ET and 52/ETJSN was defined as narrowing in joint space width over the course of the study. The JSN score summarizes the severity of JSN in 30 joints of the hands and 12 joints of the feet.

Outcome results

Primary

Change From Baseline in mTSS at Week 28

mTSS was defined as the sum of joint erosion scores graded by assessing erosion severity in 44 joints (16 per hand and 6 per feet) and JSN scores graded by assessing narrowing of joint spaces in 42 joints (15 per hand and 6 per feet). Erosion score was scored from 0 (no erosion) to 5 (complete collapse of bone) and the score for erosion ranges from 0 to 160 in the hands and from 0 to 120 in the feet (the maximum erosion score for a joint in the foot is 10). JSN including subluxation, was scored from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation), with a maximum JSN score of 168. mTSS scores ranged from 0 (normal) to 448 (worst possible total score). Change from baseline was calculated as score at week 28 (ET) minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

Change From Baseline in mTSS at Week 52

mTSS was defined as the sum of joint erosion scores graded by assessing erosion severity in 44 joints (16 per hand and 6 per feet) and JSN scores graded by assessing narrowing of joint spaces in 42 joints (15 per hand and 6 per feet). Erosion score was scored from 0 (no erosion) to 5 (complete collapse of bone) and the score for erosion ranges from 0 to 160 in the hands and from 0 to 120 in the feet (the maximum erosion score for a joint in the foot is 10). JSN including subluxation, was scored from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation), with a maximum JSN score of 168. mTSS scores ranged from 0 (normal) to 448 (worst possible total score). Change from baseline was calculated as score at week 52 (ET) minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

Change From Baseline in Percent Overall Work Impairment at Week 12

WPAI consisted of 6 questions (Q1=Employment status; Q2=Hours absent from work due to the rheumatoid arthritis; Q3=Hours absent from work due to other reasons; Q4=Hours actually worked; Q5=Impact of the rheumatoid arthritis on productivity while working; Q6=Impact of the rheumatoid arthritis on productivity while doing regular daily activities other than work). Higher WPAI scores indicated greater activity impairment. The scores were multiplied by 100 to express in percentages. Percent overall work impairment due to problem was calculated as Q2/(Q2+Q4)+\[(1-(Q2/(Q2+Q4))x(Q5/10)\]. Negative values indicate improvement from baseline.

Number of Participants With TEAEs From Week 12 to Week 28

TEAEs were defined as any AE that started or worsened in severity after initial dose of study drug or reference drug through week 52 or withdrawal. TEAEs were summarized using MedDRA (Version 11.1) by SOC and PT. Participants reporting more than 1 AE for a given MedDRA PT were counted only once for that term. Participants reporting more than 1 AE within a SOC were counted only once for the SOC total. Based on NCI-CTCAE, AEs were graded as grade 1=mild; grade 2=moderate: grade 3 = severe or medically significant, grade 4 = life threatening, grade 5 = death related to AE

Percentage of Participants Achieving Change From Baseline in mTSS <= 0.5 at Week 28 and Week 52

mTSS was defined as the sum of joint erosion scores graded by assessing erosion severity in 44 joints (16 per hand and 6 per feet) and JSN scores graded by assessing narrowing of joint spaces in 42 joints (15 per hand and 6 per feet). Erosion score was scored from 0 (no erosion) to 5 (complete collapse of bone) and the score for erosion ranges from 0 to 160 in the hands and from 0 to 120 in the feet (the maximum erosion score for a joint in the foot is 10). JSN including subluxation, was scored from 0 (normal) to 4 (complete loss of joint space, bony ankylosis, or luxation), with a maximum JSN score of 168. mTSS scores ranged from 0 (normal) to 448 (worst possible total score). An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.
