Susvimo Eye Implant for Wet AMD Approved
FDA has approved Genentech’s Susvimo (ranibizumab injection) 100 mg/mL for intravitreal use via ocular implant for treating people with wet, or neovascular, age-related macular degeneration (AMD) who have previously responded to at least two anti-vascular endothelial growth factor (VEGF) injections.
Susvimo is designed to deliver ranibizumab continuously instead of typical once-per-month anti-VEGF eye injections current treatments offer, according to the company. The implant is surgically inserted into the eye during a one-time, outpatient procedure and refilled every six months.
Approval is based on data from the Phase 3 Archway study, which showed wet AMD patients treated with Susvimo achieved and maintained vision gains equivalent to monthly ranibizumab injections, the company says. “In addition, only 1.6% of Susvimo patients received supplemental ranibizumab treatment before their first refill, and more than 98% could go six months before their first refill.”
Regarding safety, Genentech says the Susvimo implant has been associated with a three-fold higher rate of endophthalmitis than monthly intravitreal injections of ranibizumab. “Many of these events were associated with conjunctival retractions or erosions,” it says. “Appropriate conjunctiva management and early detection with surgical repair of conjunctival retractions or erosions may reduce the risk of endophthalmitis.”
