Article Synopsis
  • The study aimed to evaluate the effects of changing rheumatoid arthritis treatment from adalimumab to sarilumab for patients who partially responded to adalimumab in a clinical trial.
  • Researchers assessed various disease activity measures to determine how many patients experienced meaningful improvements or worsening after the switch.
  • Results showed that most partial responders to adalimumab who switched to sarilumab experienced either improvement or no change in disease activity, alleviating concerns about potential worsening with the treatment switch.

Introduction: The efficacy of sarilumab and upadacitinib, in combination with disease-modifying antirheumatic drugs (DMARDs), was demonstrated in phase 3 clinical trials of patients with rheumatoid arthritis (RA) refractive to previous biologic DMARDs. In the absence of head-to-head clinical trials, the matching-adjusted indirect comparison (MAIC) and simulated treatment comparison (STC) estimate the relative efficacy of sarilumab and upadacitinib in patients with RA who had an inadequate response to previous biologic DMARDs.

Methods: Patient-level data for sarilumab were obtained from the TARGET trial (NCT01709578) and published aggregate data for upadacitinib were obtained from the SELECT-BEYOND trial (NCT02706847).

Article Synopsis
  • In rheumatoid arthritis (RA) patients, a condition called disproportionate articular pain (DP) causes joint pain that is more severe than the swelling suggests, affecting about 23% of patients in a study.
  • The study analyzed data from various trials to assess the impact of sarilumab, an IL-6 inhibitor, on patients with and without DP, revealing that those treated with sarilumab were more likely to become DP-free.
  • Results indicate that while inflammation is a factor in RA, other mechanisms may also play a role in causing DP, highlighting potential pathways for further investigation in treatment strategies.

Article Synopsis
  • Rheumatoid arthritis treatment often fails, and while targeted therapies exist, many patients do not achieve lasting remission; machine learning was used to predict responses to two specific treatments, sarilumab and adalimumab, using blood biomarkers.
  • A decision tree model was developed using trial data to create a predictive rule, finding that specific antibodies and inflammation markers can indicate who will respond well to sarilumab.
  • This predictive rule was successfully validated across multiple trials and suggests that tailoring treatments based on these biomarkers could improve outcomes for patients by identifying the best drug for their condition.

We assessed pharmacokinetics (PK), pharmacodynamics (PD), and PK/PD relationships of interleukin-6 (IL-6), soluble IL-6 receptor, and C-reactive protein (CRP) in serum, and absolute neutrophil count (ANC) in blood following single doses of subcutaneous sarilumab versus intravenous tocilizumab (NCT02097524) from patients with rheumatoid arthritis (RA) who are inadequate responders to methotrexate (MTX) and on a stable dose of MTX. Patients with RA randomized (1:1:1:1) to single-dose sarilumab (150 or 200 mg subcutaneously) or tocilizumab (4 or 8 mg/kg intravenously) were included (n = 101), and PK, PD, and PK/PD relationships and safety were assessed over 6 weeks postdose. PK profiles for both drugs are described by parallel linear and nonlinear target-mediated clearance pathways.

Background: Interleukin-6 (IL-6) is a pleiotropic cytokine that plays a key role in the pathogenesis of rheumatoid arthritis. Sarilumab is a human monoclonal antibody that binds membrane-bound and soluble IL-6 receptor-α to inhibit IL-6 signalling. The aim of this study was to compare the effects of sarilumab and adalimumab (a tumour necrosis factor alpha inhibitor) monotherapy on levels of circulating biomarkers associated with the acute-phase response, bone remodelling, atherothrombosis, anaemia of chronic disease and markers purported to reflect synovial lymphoid and myeloid cell infiltrates, as well as the potential of these biomarkers to differentially predict clinical and patient-reported outcomes with sarilumab vs.
