Abstract PURPOSE The inflammatory, angiogenic and neurogenic pathways of osteoarthritis (OA) might already be present in patients with patellofemoral pain (PFP), a supposed precursor of OA. In this study, differences in serum levels of biomarkers of inflammation, angiogenesis and neurogenesis were compared between PFP patients and healthy controls. Furthermore, we aimed to determine the associations […]

Abstract OBJECTIVE This study aims to explore the associations between clinical characteristics, including medical history, and the frequency, severity, and type of pain events (PEs) over a two-year period in patients with knee osteoarthritis (OA). DESIGN A post-hoc analysis was conducted on data from two double-blinded, randomized, placebo-controlled, multicenter phase-III trials assessing the efficacy and […]

Abstract OBJECTIVE To explore associations between patient-reported pain outcomes and knee osteoarthritis (OA) subtypes based on systemic biochemical markers and joint structural pathology as defined by MRI. METHODS Data were obtained from 297 knee OA patients from the IMI-APPROACH study. Pain outcomes were assessed using the KOOS, WOMAC, ICOAP, NRS, PainDETECT, and a pain diary. […]

Abstract OBJECTIVE The Foundation for National Institutes of Health (FNIH) OA Biomarkers Consortium aims to identify and qualify biomarkers to support drug development in knee osteoarthritis (OA). The PROGRESS OA study aims to externally validate prognostic biomarkers identified in the earlier Phase I study. DESIGN PROGRESS OA included data from the control arms of several […]

Abstract OBJECTIVE The inflammatory endotype is arguably one of the most well-established endotype in osteoarthritis (OA). While endotyping holds promise for advancing drug development, numerous potential challenges must be considered, addressed and resolved before successful clinical outcomes can be achieved. DESIGN Since 2017, the Osteoarthritis Research Society International (OARSI) has hosted the Clinical Trials Symposium […]

Abstract OBJECTIVE The development of disease-modifying drugs is limited by OA’s heterogeneity and the challenge of defining clinical endpoints. Serological biomarkers are considered potential surrogate endpoints, but their contribution from single joints to systemic levels in OA patients is unclear. In this exploratory study we longitudinally assessed systemic biomarker levels’ response to tissue damage and […]

Abstract OBJECTIVES To efficiently assess the disease-modifying potential of new osteoarthritis treatments, clinical trials need progression-enriched patient populations. To assess whether the application of machine learning results in patient selection enrichment, we developed a machine learning recruitment strategy targeting progressive patients and validated it in the IMI-APPROACH knee osteoarthritis prospective study. DESIGN We designed a […]

Abstract OBJECTIVE Arthritic cartilage is primed for mechanical damage. Joint biochemical markers (JBM) could provide insight into the impact of mechanical stimulation on joint tissue turnover in osteoarthritis (OA) of potential use in clinical OA research and practice. However, existing studies of the acute impact of physical activities (PA) on JBM often contain risks of […]

Abstract BACKGROUND The lack of disease modifying drugs in Osteoarthritis (OA) may be attributed to the difficulty in robust response based on patient-reported outcomes (PROs) linked to drug mechanism of action. Joint tissue turnover biomarkers are associated with disease progression. A subset of patients has elevated serum levels of CRP metabolite (CRPM). This explorative study […]

Abstract OBJECTIVE To examine the effect of dynamic compressive loading applied intermittently on bovine cartilage explants stimulated with proinflammatory cytokines over 21 days. DESIGN Cartilage explants were cultured for 21 days with Oncostatin M and TNFα (O ​+ ​T) [10/5 ​ng/mL] or in culture medium alone (w/o). The explants were either left free-swelling or subjected to dynamic compressive […]
