Brief Summary:
The objective of this study was to verify the superiority of ASP015K alone or in combination with disease-modifying antirheumatic drugs (DMARDs) over placebo in terms of efficacy in participants with rheumatoid arthritis (RA) who had an inadequate response to DMARDs

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Drug: Peficitinib Drug: Placebo Biological: Etanercept Phase 3

Detailed Description:

This was a multi-center, randomized, placebo-controlled, double-blind, parallel-group, confirmatory study to evaluate the efficacy and safety of ASP015K alone or in combination with DMARDs in participants with RA who had an inadequate response to DMARDs.

Etanercept was also administered as the reference drug in an open-label manner. The study drug was orally administered once daily (QD) after breakfast for 52 weeks. Etanercept was administered subcutaneously QD for 52 weeks. At Week 12, participants in the placebo group were switched to ASP015K.

The dose of ASP015K to be started at Week 12 for the placebo group was determined randomly at baseline in advance and switched in a blinded manner.

Participants in ASP015K group or placebo groups who had completed the study were eligible for participation in an open-label extension study (015K-CL-RAJ2).

  67. Number of Participants With Adverse Events During the First 12 Weeks [ Time Frame: Week 0 to Week 12 ]
    Treatment-emergent adverse events (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 System Organ Class (SOC) and Preferred Term (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 National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) grade: grade 3 = severe or medically significant, grade 4 = life threatening, grade 5 = death related to AE.

    Treatment-emergent adverse events (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.
