Switching to infliximab biosimilar may lead to more ocular flares in for non-infectious uveitis

Switching from infliximab to a biosimilar infliximab-abda for non-infectious uveitis may lead to more ocular flares, according to a study published in the American Journal of Ophthalmology.

In this retrospective case series, 17 patients with non-infectious uveitis who were switched from originator infliximab to biosimilar infliximab-abda for non-medical reasons, were included.

More ocular flares per person-years were experienced after switching to infliximab-abda (0.92) than with the originator infliximab (0.19, P = 0.028).

Of the 6 patients who experienced flares after switching to infliximab-abda, 66.7% occurred within 90 days of switching. A single patient who flared on originator infliximab went on to develop a single flare on infliximab-abda.

The study authors cautioned provider to monitor patient closely for the first 90 days after switching to infliximab biosimilar.
