Title: Rheumatoid Arthritis – Small Molecules, Biologics and Gene Therapy Poster I: Comorbidities and Adverse Events; Efficacy and Safety of Small Molecules

Session Type: ACR Poster Session A

Session Time: 9:00AM-11:00AM

Background/Purpose:  

The purpose of this analysis was to assess whether early improvement in ACR components could act as predictors of low disease activity (LDA) or remission (REM) at Week 12 in Phase 3 trials of baricitinib (BARI). The patient’s assessment of pain, a patient-reported outcome measured by a 0-100 mm visual analog scale (VAS), was a focus for this analysis.

Methods:

In RA-BEAM1, 487 patients with inadequate response (IR) to methotrexate (MTX) were randomized to BARI 4 mg once daily. In RA-BEACON2, a trial of bDMARD-IR patients, 174 patients were randomized to BARI 2 mg and 177 to BARI 4 mg once daily. In RA-BUILD3, a trial with csDMARDs-IR patients, 229 patients were randomized to BARI 2 mg and 227 to BARI 4 mg once daily. LDA was defined as CDAI ≤10 or DAS28-ESR ≤3.2 and REM as CDAI ≤ 2.8 or DAS28-ESR<2.6 at Week 12. Early improvement, changes from baseline to Week 4, for each of the ACR components (pain VAS, patient global assessment of disease activity [PtGA], physician global assessment of disease activity [PGA], swollen joint count, tender joint count [TJC], HAQ-DI, hsCRP, and ESR) was evaluated on their respective predictability for LDA or REM at Week 12 using area under the curve (AUC) of receiver operating characteristic (ROC) curves. The optimum cutoff-point in percent improvement at Week 4 was evaluated based the Youden index and the negative predictive value (NPV).

Results:

Early improvement in pain VAS, TJC, PtGA, and PGA had among the highest predictability, whereas hsCRP and ESR had among the lowest, as measured by AUC of ROC (Figs. 1 and 2 for RA-BEAM data), for achieving both LDA and REM at Week 12. A threshold of 30-50% improvement in pain from baseline to Week 4 had the optimum range for predicting LDA and REM at Week 12 (Table). Consistent results were observed for csDMARD-IR and bDMARD-IR patients, and these results were similar for both BARI 2 mg and BARI 4 mg doses.

Conclusion:

In these trials, patients with a lack of early response to BARI, as assessed by improvement in pain VAS at Week 4, tended to be less likely to achieve LDA or REM at Week 12 vs. patients with an early response. A minimum of 30% improvement in pain resulted in optimum NPV in this analysis.

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].
