Title: 4M046: Plenary II (1758–1763)

Session Type: Plenary Session II

Session Time: 11:00AM-12:30PM

Background/Purpose: No studies have assessed the effect of methotrexate (MTX) in osteoarthritis of the hand (HOA). The purpose of our study was to examine the effect of MTX on pain and structural progression in symptomatic erosive HOA (EHOA).

Methods: This 1-year prospective, monocentric, randomized, double-blind, placebo-controlled study (NCT1968405) followed patients with symptomatic EHOA. Patients were randomized into two groups: 10 mg MTX per week or placebo. The primary endpoint was pain assessment at 3 months, and secondary endpoints were clinical features (pain on visual analog scale (VAS)), radiographic features (Verbruggen anatomical radiographic score and Gent University Score System), and magnetic resonance imaging (MRI) at 12 months.

Results: Sixty-four EHOA patients were randomized to either the placebo or MTX group. At 3 months, there was no significant difference in the mean decrease in VAS pain score (mm) (MTX: 17.5 (28.4) vs placebo: 8.4 (25.2); p=0.2). Erosive joints progressed significantly more to a remodeling phase in the MTX group than in the placebo group (27% vs 15%) (p=0.03). Joints with joint space loss appeared to be less eroding in the MTX group than in the placebo group (8% vs 29%; p=0.2). Interleukin-6 level (p< 0.0001) and synovitis findings on MRI (p=0.02) at baseline were found to be predictive factors for erosive structural evolution of non-erosive joints. Conclusion: Our study shows that MTX did not demonstrate superior efficacy over placebo on pain and function evolution at 3 and 12 months in subjects with EHOA.. However, MTX significantly reduced the progression of joint damage compared to placebo and seems to facilitate bone remodeling. The presence of systemic and local inflammations at baseline were predictors of erosive progression.

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].
