The interleukin (IL)-1β inhibitor canakinumab (Ilaris) showed promise for preventing the need for hip or knee replacement among patients with osteoarthritis in an exploratory analysis of data from a randomized clinical trial, investigators reported.
Among patients enrolled in CANTOS, the pooled incidence rate for total hip replacement/total knee replacement was 0.31 events per 100 person-years for those receiving the monoclonal antibody every 3 months for up to 5 years compared with 0.54 per 100 for those given placebo, according to Paul M. Ridker, MD, of Harvard Medical School in Boston, and colleagues.
