Title: Epidemiology and Public Health Poster I

Session Type: Poster Session B

Session Time: 9:00AM-10:30AM

Background/Purpose: To assess the risk of major adverse cardiovascular events (MACEs) and venous thromboembolism events (VTEs) among patients initiating a Janus kinase inhibitor (JAKi) (tofacitinib and baricitinib) versus adalimumab in a large real-world population of patients with rheumatoid arthritis.

Methods: We conducted a nationwide population-based cohort study of the French national health data system, the exposed group initiating a JAKi and non-exposed group initiating adalimumab. We included all individuals who had their first dispensation of a JAKi or adalimumab between July 1, 2017 and May 31, 2021, and had rheumatoid arthritis with no history of cardiovascular diseases. The primary endpoints were the occurrence of a MACE or VTE. Weighted hazard ratio (HRw) values were estimated with the inverse probability of treatment weighting method to account for confounding factors.

Results: The cohort included 14,632 patients: 7,972 and 6,660 in the exposed (mean age 58.5 years, female 80.1%) and non-exposed (mean age 54.6 years female 72.2%) groups. During follow-up, 40 and 28 MACEs and 62 and 24 VTEs occurred in the exposed and non-exposed groups, respectively. Risk of MACEs for the exposed versus non-exposed group was not significant: HRw 1.1 [95% CI 0.6-1.7] (p=0.84), nor was risk of VTEs significant: HRw 1.3 [0.8-2.1] (p=0.23). Despite a lack of power, results were consistent among patients aged 65 years or older with at least one cardiovascular risk factor.

Conclusion: This study provides reassuring data regarding the risks of MACEs and VTEs in patients initiating a JAKi versus adalimumab, including patients at high risk of cardiovascular diseases.

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].
