Sprifermin (rhFGF18) Modulates Extracellular Matrix Turnover in Cartilage Explants ex vivo

BACKGROUND:
Sprifermin (recombinant human fibroblast growth factor 18) is in clinical development as a potential disease-modifying osteoarthritis drug (DMOAD). In vitro studies have shown that cartilage regenerative properties of sprifermin involve chondrocyte proliferation and extracellular matrix…

Development and use of biochemical markers in osteoarthritis: current update

PURPOSE OF REVIEW:
There is an increasing demand for noninvasive and descriptive biochemical markers (biomarkers) in osteoarthritis; for enabling early drug development (including translational research), evaluating clinical trial at an early stage and for subtyping. Purpose of the review is to rev…

Biochemical marker discovery, testing and evaluation for facilitating OA drug discovery and development

Osteoarthritis (OA) is the most common form of joint disease. This presents the OA research community and pharmaceutical companies developing disease-modifying OA drugs (DMOADs) with great opportunities. The different OA subtypes complicate the traditional approaches for developing new treatments. I…

Biomarkers for equine joint injury and osteoarthritis

We report the results of a symposium aimed at identifying validated biomarkers that can be used to complement clinical observations for diagnosis and prognosis of joint injury leading to equine osteoarthritis (OA). Biomarkers might also predict pre-fracture change that could lead to catastrophic bon…

A machine learning approach for the identification of new biomarkers for knee osteoarthritis development in overweight and obese women

OBJECTIVE:
Knee osteoarthritis (OA) is among the higher contributors to global disability. Despite its high prevalence, currently, there is no cure for this disease. Furthermore, the available diagnostic approaches have large precision errors and low sensitivity. Therefore, there is a need for new …

Sprifermin (rhFGF18) enables proliferation of chondrocytes producing a hyaline cartilage matrix

OBJECTIVE:
Fibroblast growth factor (FGF) 18 has been shown to increase cartilage volume when injected intra-articularly in animal models of osteoarthritis (OA) and in patients with knee OA (during clinical development of the recombinant human FGF18, sprifermin). However, the exact nature of this e…

Effects of dietary weight loss with and without exercise on interstitial matrix turnover and tissue inflammation biomarkers in adults with knee osteoarthritis: the Intensive Diet and Exercise for Arthritis trial (IDEA)

OBJECTIVE:
To examine the effects of dietary weight loss, with and without exercise, on selected soluble biomarkers in overweight and obese older adults with symptomatic knee osteoarthritis (OA).

DESIGN:
Blood samples were analyzed from 429 participants in the Intensive Diet and Exercise for Ar…

Biomarker of extracellular matrix remodelling C1M and proinflammatory cytokine IL-6 are related to synovitis and pain in endstage knee osteoarthritis patients

Little is known about local and systemic biomarkers in relation to synovitis and pain in end-stage osteoarthritis (OA) patients. We investigated the associations between the novel extracellular matrix biomarker, C1M, and local and systemic interleukin 6 (IL-6) with synovitis and pain. Serum C1M, pla…

Chondrocyte secretome: a source of novel insights and exploratory biomarkers of osteoarthritis

The extracellular matrix (ECM) of articular cartilage is comprised of complex networks of proteins and glycoproteins, all of which are expressed by its resident cell, the chondrocyte. Cartilage is a unique tissue given its complexity and ability to resist repeated load and deformation. The mechanism…
