Objective: Treat-to-target is recommended in the management of rheumatoid arthritis (RA) but its implementation is suboptimal. We aimed to identify interventional strategies targeted at improving treat-to-target implementation in RA by systematically reviewing published evidence on barriers to, facilitators of, and interventions to support treat-to-target implementation.

Methods: Systematic and scoping literature searches in PubMed/MEDLINE, BIOSIS Previews, Derwent Drug File, Embase, EMCare, International Pharmaceutical Abstracts, and SciSearch were conducted to identify barriers/facilitators and interventions relating to treat-to-target implementation in RA.

Article Synopsis
  • The study assessed how a Patient Support Program (PSP) from a sponsoring company affected the continuation of adalimumab treatment among adult Australian patients with various inflammatory conditions.
  • Patients were divided into those who opted for the PSP and those who didn’t, with a follow-up period of 12 months.
  • Results indicated no significant difference in treatment discontinuation rates between the PSP group and non-PSP group, but the PSP group had greater persistence compared to a historical group that did not receive support.

Article Synopsis
  • Recent treatment guidelines for ankylosing spondylitis (AS) now recommend advanced therapies like TNF inhibitors, IL-17 inhibitors, and JAK inhibitors as first-line options, leading to a study assessing these therapies' clinical and economic benefits.
  • A systematic review analyzed various randomized clinical trials for JAK inhibitors (upadacitinib, tofacitinib), IL-17 therapies (secukinumab, ixekizumab), and TNF inhibitors (adalimumab, etanercept, golimumab) to determine their effectiveness and cost-effectiveness for AS treatment.
  • Results showed that upadacitinib offered the highest ASAS40 response rate and lowest cost per responder, while also having the least treatment

Background: The objective of this post-hoc analysis was to assess the efficacy and safety of upadacitinib in psoriatic arthritis (PsA) patients with axial involvement.

Methods: Post-hoc analysis of SELECT-PsA 1 and SELECT-PsA 2 in patients randomized to upadacitinib 15 mg (UPA15), placebo (switched to UPA15 at week 24), or adalimumab 40 mg (ADA; SELECT-PsA 1 only). Axial involvement was determined by investigator judgement (yes or no; based on the totality of available clinical information, such as duration and characteristics of back pain, age of onset, and previous lab investigations and imaging, if available) alone, or investigator judgement and patient-reported outcome (PRO)-based criteria (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] ≥ 4 and BASDAI Q2 ≥ 4).

Osteoarthritis (OA) affects more than 240 million people worldwide. In 2016, the Osteoarthritis Research Society International submitted a report to the United States Food and Drug Administration highlighting OA as a 'serious' disease, and appealed for the urgent development and review of new therapies to address a significant unmet need. Despite this, international guidelines for the treatment of OA have been largely unchanged for over a decade.

The treat-to-target strategy, which defines clinical remission as the primary therapeutic goal for rheumatoid arthritis (RA), is a widely recommended treatment approach in clinical guidelines. Achieving remission has been associated with improved clinical outcomes, quality of life, and productivity. These benefits are likely to translate to reduced economic burden in terms of lower healthcare costs and resource utilization.

Rheumatoid arthritis (RA) is a disease characterised by inflammation of synovial joints and poses a substantial healthcare burden on both the individual and society. One of the most significant shifts in the RA therapeutic landscape has occurred with the introduction of biological disease modifying anti-rheumatic drugs (bDMARDs). There are five classes of bDMARDs currently available, each with a different molecular target and subtle differences in their efficacy and safety profile.

Purpose: While the aetiology of rheumatoid arthritis (RA) remains unclear, many of the inflammatory components are well characterised. For diagnosis and therapy evaluation, in vivo insight into these processes would be valuable. Various imaging probes have shown value including dynamic contrast-enhanced (DCE) MRI and PET/CT using F-fluorodeoxyglucose (F-FDG) or tracers targeting the translocator protein (TSPO).
