Title: RA – Diagnosis, Manifestations, & Outcomes Poster II: Miscellaneous Aspects of RA (0786–0812)

Session Type: Poster Session B

Session Time: 8:30AM-10:30AM

Background/Purpose: The aim of this analysis was to compare between enrolment periods RA treatment outcomes and frequency of treating to target, and to assess the impact of target type on long-term function.

Methods: This is a post-hoc analysis of data from the Biologic Treatment Registry Across Canada (BioTRAC). Patients with RA who initiated treatment with infliximab or subcutaneous golimumab were included. Patients were grouped into enrolment periods: 2002-2004, 2005-2008, 2009-2012, 2013-2015, 2016-2017. Achievement of LDA (CDAI LDA or SDAI LDA or SJC≤1), remission (CDAI remission or SDAI remission or SJC=0), and sustained LDA or remission (at 6 and 12 months) were compared between enrolment periods with the Chi-square test and multivariate logistic regression. The impact of achieving LDA or remission at 6 months, 12 months, or both (sustained) on HAQ-DI at 18 months was assessed with one-way ANOVA and generalized linear models.

Results: 1420 patients treated with anti-TNFs (IFX: n=890; GLM: n=530) were included. Over calendar time, a significant decrease in baseline disease duration and disease activity scores (CDAI, SDAI, SJC28, TJC28, HAQ) was observed (p < 0.001).

Across enrolment periods, significant differences were observed in target achievement with higher rates observed in more recent years. Upon adjusting for baseline CDAI and prior biologic exposure, no differences between enrolment periods were observed in achieving LDA, remission or sustained LDA/remission at 6 months; however, significantly (p=0.030) higher odds of achieving remission at 12 months were observed in more recent years.

Among patients not achieving LDA at 6 and 12 months, an intervention was applied in approximately 40% of patients, without significant differences between enrolment periods. Between 6 and 12 months, the most common intervention was anti-TNF discontinuation (64.9% of non-LDA achievers), followed by DMARD addition (9.8%), NSAID addition (8.8%), or steroid addition (7.2%). Similar results were obtained post 12 months.

Patients achieving sustained LDA, followed by those achieving LDA either at 6 or 12 months had significantly lower HAQ-DI at 18 months compared to patients not achieving LDA at either timepoint (0.8 vs. 1.1 vs. 1.4; p< 0.001). Similar results were observed when evaluating achievement of disease remission albeit with greater impact on HAQ-DI at 18 months (0.7 vs. 1.1 vs. 1.2; p< 0.001). Adjustment for baseline HAQ-DI did not impact the results.

Conclusion: Target achievement has increased over time although emphasis in treating to target may be placed in the first 6 months of treatment. Achieving stricter targets was associated with better long-term patient function.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
