All biologics aren’t equal when it comes to anterior uveitis risk
An analysis of Swedish Rheumatology Quality Register data presented at the 2020 EULAR meeting concluded that, among 3,568 patients started on one of four biologics for treatment of spondyloarthritis, the incidence of anterior uveitis was 2.9 per 100 patient-years in those on infliximab (Remicade), 4.0 per 100 patient-years with adalimumab (Humira), 6.8 per 100 patient-years with secukinumab (Cosentyx), and 7.5 per 100 patient-years with etanercept (Enbrel).

“This is important information for us in the clinic. The big question has been, do we see a reduced risk of anterior uveitis with secukinumab, an interleukin-17 inhibitor,” observed RWCS director Arthur Kavanaugh, MD, professor of medicine and director of the Center for Innovative Therapy in the division of rheumatology, allergy, and immunology at the University of California, San Diego.
“When I’ve switched people with uveitis to secukinumab or ixekizumab [Taltz], I do see it come back. So I think it’s important to have these data out there,” Dr. Ogdie said.
Certolizumab pegol markedly reduced the incidence of anterior uveitis flares in patients with radiographic and nonradiographic axSpA and a history of recurrent uveitis flares in the ongoing phase 4 C-VIEW study. In the 48 weeks prior to going on certolizumab pegol, the 89 participants included in this analysis had an acute anterior uveitis incidence of 1.5 episodes per patient; during their first 48 weeks on the TNF inhibitor, the rate plunged to 0.2 episodes, representing an 87% reduction.
Secukinumab ‘not the obvious choice’ after inadequate response to a TNF inhibitor
While it might seem logical to turn to an IL-17 inhibitor in patients with an inadequate response to one or more TNF inhibitors, two recently published studies suggest that starting secukinumab is not more effective than trying yet another TNF inhibitor.
A retrospective analysis of Swiss registry data on next-step therapy in 390 axSpA patients who had withdrawn from one or more TNF inhibitors concluded that efficacy at 1 year in the 106 who switched to secukinumab wasn’t significantly different than in the 284 who moved on to another TNF inhibitor.
Similarly, an analysis of 10,583 courses of biologic therapy in 8,050 axSpA patients in five Nordic registries concluded that secukinumab and adalimumab as second-line therapy in patients with inadequate response to an initial TNF inhibitor performed similarly through 1 year of follow-up. However, in patients who’d previously failed to respond to two or three different biologic agents, adalimumab proved superior to the interleukin-17 inhibitor.
“These are two studies that don’t support the intuitive notion of trying a drug with a different mechanism of action when a patient has an inadequate response to a TNF inhibitor. It’s not clear that’s going to make a difference. It doesn’t mean secukinumab can’t work, but it means secukinumab is not the obvious choice,” Dr. Ruderman commented.
