Lorecivivint, an intra-articular potential disease-modifying osteoarthritis drug

Introduction: Osteoarthritis (OA) is the most common form of arthritis. Knee OA is associated with joint pain, activity limitation, physical disability, reduced health-related quality of life, and increased mortality. To date, all pharmacologic treatments for OA are directed toward pain management. Lorecivivint (LOR) is an investigational agent that has potential as a disease-modifying osteoarthritis drug (DMOAD). It modulates the Wnt signaling pathway by inhibiting CDC-like kinase 2 and dual-specificity tyrosine phosphorylation-regulated kinase 1 A which are molecular regulators in Wnt signaling, chondrogenesis, and inflammation. Areas covered: This paper discusses the current pharmacologic guidelines for the treatment of knee OA and illuminates the potential of a new agent, Lorecivivint, as a disease-modifying osteoarthritis drug (DMOAD). Efficacy and safety and the challenges for this novel agent come under the spotlight. Expert opinion: LOR may be a potential DMOAD for the treatment of patients with knee OA. While the Phase 2A trial did not meet its primary endpoint, preplanned analyses did identify a target population for further evaluation of its potential as a DMOAD. Phase 3 trials are ongoing, but this intra-articular drug is currently considered safe and well tolerated, with no significant reported systemic side effects.
