3-year, open-label study evaluating safety, tolerability, and efficacy of lorecivivint in subjects with osteoarthritis of the knee

Conditions: Osteoarthritis of the Knee

Summary: this study is designed as a 3-year, multicenter, open-label study evaluating the safety, tolerability, and efficacy of intra-articular (ia) lorecivivint (lor) in subjects with osteoarthritis of the knee in a real-world setting.

at day 1, after a screening period of up to 14 days, subjects will receive an ia injection of 0.07 mg lor into one or both knees, followed by a 36-month evaluation period. clinic visits will be scheduled at day 1, and months 3, 12, 24, and 36 \[end of study (eos)\] or early termination (et) for completion of all patient reported outcome (pro) measurements western ontario and mcmaster university arthritis index (womac), knee injury and ostheoarthritis outcome score (koos), pain numeric rating scale (nrs), study form (sf)-12, patient acceptable symptom state questionnaire (pass), work productivity and activity impairment questionnaire (wpai)\], functional tests \[40-meter walk test and time up and go (tug) test at a subset of sites\], and safety evaluations. on day 1, the charlson comorbidity index and widespread pain index and symptom severity \[wpi\&ss\] assessments will also be completed. a phone visit for safety follow-up will occur 4 weeks after the injection on day 1. subjects may also have unscheduled injection visits for additional injections of lor, glucocorticoid, or hyaluronic acid (ha). following each injection, subjects will return to the clinic for 3-month post-injection follow-up visits, unless another visit has occurred between the injection and the 3-month post injection date. at these injection visits and 3-month post-injection follow-up visits, subjects will complete pro measurements and functional tests (at a subset of sites).
