Introduction: ORAL Surveillance, a post-authorisation safety study of patients with rheumatoid arthritis (RA) enriched for cardiovascular (CV) risk, demonstrated increased risk of major adverse CV events (MACE) and malignancies (excluding non-melanoma skin cancer [NMSC]) for tofacitinib versus tumour necrosis factor inhibitors (TNFi). This analysis of a real-world Canadian observational study evaluated tofacitinib safety/effectiveness in patients meeting or not meeting CV risk criteria.

Methods: CANTORAL included patients with moderate-to-severe RA initiating tofacitinib (10/2017-07/2020; N = 504).

Introduction: Routine care studies of psoriatic arthritis (PsA) and ankylosing spondylitis (AS) demonstrated attenuated responses to tumor necrosis factor inhibitors in current/past versus never smokers. This post hoc analysis assessed tofacitinib efficacy and safety in patients with PsA or AS by cigarette smoking status at trial screening.

Methods: Pooled data from phase 3 and long-term extension (safety only) PsA trials and phase 2 and 3 AS trials were assessed by current/past versus never smoker status.

Article Synopsis
  • The study aimed to evaluate how common major depressive disorder and generalized anxiety disorder (pMDD/pGAD) are in patients with moderate to severe rheumatoid arthritis (RA) and assess the impact of tofacitinib on RA symptoms based on mental health status.
  • Researchers analyzed data from several phase 3 clinical trials involving patients treated with tofacitinib, adalimumab, or placebo while measuring mental health using the SF-36 survey.
  • Results showed that patients taking tofacitinib had significant improvement in mental health scores compared to those on adalimumab or placebo, and the rate of pMDD/pGAD decreased over the year, indicating that effective RA treatment might also enhance mental health outcomes.

Article Synopsis
  • The study assessed the effects of sex on the effectiveness, safety, and persistence of tofacitinib in patients with psoriatic arthritis, using data from two phase 3 trials.
  • Findings showed that while tofacitinib was effective for both males and females at 3 months, women were less likely to achieve minimal disease activity compared to men, likely because of differences in health status at the start.
  • Both sexes experienced similar rates of adverse effects and discontinuation, indicating that tofacitinib's safety profile and retention rates were comparable regardless of sex.

Introduction: The SmartClic/ClicWise autoinjector is a new reusable, multi-use, single-patient device for the administration of subcutaneously administered biologics in the treatment of chronic conditions, including rheumatoid arthritis. The device will be used in conjunction with a mobile application (app). The aim of this study was to collect feedback on the usability, functionality, and applicability of the device and the companion app from health care professionals (HCPs) who perform injections as part of their role and care for patients with rheumatic conditions.

Introduction: This study characterized real-world demographic and baseline clinical characteristics, as well as treatment persistence and adherence, in patients with psoriatic arthritis (PsA) who had newly initiated tofacitinib treatment.

Methods: This retrospective cohort study included patients aged 18 years or older in the IBM MarketScan™ US database with at least one tofacitinib claim (first = index) between December 14, 2017 and April 30, 2019; PsA diagnoses on/within 12 months pre-index; and no diagnoses of rheumatoid arthritis any time pre-index. Patients were continuously enrolled for 12 months pre-index and 6 months post-index, with no pre-index claims for tofacitinib.

  • * A post hoc analysis pooled data from three Phase 3 trials, indicating significant improvements in patient-reported outcomes after 6 months of treatment with tofacitinib.
  • * The study found strong correlations between fatigue scores and overall health scores, suggesting that reducing fatigue may lead to better overall quality of life in RA patients.

Introduction: Comparative data on the economic burden of alopecia areata relative to the general population are limited. The objective of this retrospective database analysis was to evaluate healthcare resource utilization and direct medical costs among patients with alopecia areata from the US payer perspective compared with matched controls.

Methods: Validated billing codes were used to identify patients with alopecia areata from the IQVIA PharMetrics Plus (2016-2018) who had continuous pharmacy and medical enrollment for 365 days both before (baseline period) and after (evaluation period) the index date.

Introduction: Atopic dermatitis (AD) is a chronic and relapsing inflammatory skin disease that negatively impacts overall health, quality of life (QoL), and work productivity. Prior studies on AD burden by severity have focused on moderate-to-severe disease. Here, we describe the clinical and humanistic burden of AD in Europe across all severity levels, including milder disease.

Background: Biologic therapies are often used in patients with ulcerative colitis (UC) who are nonresponsive to conventional treatments. However, nonresponse or loss of response to biologics often occurs, leading to dose escalation, combination therapy, and/or treatment switching. We investigated real-world treatment patterns of biologic therapies among patients with UC in the USA.

The approval of new medicinal agents requires robust efficacy and safety clinical trial data demonstrated to be applicable to population subgroups. Limited data have previously been reported by drug sponsors on the topic of clinical trial diversity. In order to establish a baseline of diversity in our clinical trials that can be used by us and other sponsors, an analysis of clinical trial diversity was conducted covering race, ethnicity, sex, and age.

Objective: To describe the efficacy of tofacitinib in reducing pain in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) in a post-hoc analysis of randomised controlled trials.

Methods: Data were collected from patients in seven tofacitinib studies: six phase III (four RA, two PsA) and one phase II study (AS), and grouped into five analysis populations based on rheumatic disease diagnosis and category of prior inadequate response (IR) to treatment: conventional synthetic disease-modifying antirheumatic drugs-IR (RA and PsA), tumour necrosis factor inhibitors-IR (RA and PsA), or non-steroidal anti-inflammatory drugs-IR (AS). Only patients who received tofacitinib 5 or 10 mg twice daily or placebo were included.

Introduction: No published studies exist comparing the effectiveness of tofacitinib with other advanced therapies for the treatment of rheumatoid arthritis (RA) in real-world clinical practice. Here, we report differences in effectiveness of tofacitinib compared with standard of care, tumor necrosis factor inhibitors (TNFi), with or without concomitant methotrexate (MTX), using US Corrona registry data.

Methods: This observational cohort study included RA patients receiving tofacitinib (from 6 November 2012; N = 558) or TNFi (from 1 November 2001; N = 8014) with or without MTX until 31 July 2016.
