Vabysmo▼ and Phase 3 Intraocular Inflammation Subgroup Analysis
This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions.
This article responds to your request for information on Vabysmo® (faricimab) and details related to the intraocular inflammation (IOI) events reported in the Phase 3 studies through Year 2. This response was developed according to the principles of evidence-based medicine and summarizes data from the pivotal Phase 3 studies.
Last updated August 12, 2023
Summary
- The overall incidence of IOI in patients treated with faricimab was low
- DME — 1.4% and 1.7%, in the Vabysmo Q8W and PTI arms, respectively.
- nAMD — 3.0% in the Vabysmo up to Q16W arm.
- A subgroup analysis was performed in the patients with an IOI in the Phase 3 studies YOSEMITE/RHINE and TENAYA/LUCERNE with an IOI.
- Across the four Phase 3 studies, the majority of IOI patients had an anterior chamber cell grade or a vitreous cell grade <2+. The majority were treated with topical steroids only.
- In YOSEMITE/RHINE, the incidence and per-injection rate of IOI rates were low across treatment arms and considered comparable. In TENAYA/LUCERNE, the incidence of IOI rates were low across both arms, with approximately 2 more IOI events per 1000 injections in the Vabysmo arm compared with the aflibercept arm.
- The majority of events were non-serious. There were no IOI events associated with vision loss of ≥30 letters. The majority of events were resolved or resolving.
- The number of IVT injections prior to the first event were similar across treatment groups, and ranged from 6.5 to 7.9.

Reporting of IOI in Phase 3 clinical trials
The safety and efficacy of Vabysmo in 3,220 patients with nAMD or DME were assessed in four Phase 3 clinical studies: 2 studies were conducted in nAMD (TENAYA/LUCERNE)[5,6] and 2 studies were conducted in DME (YOSEMITE/RHINE).[3,4]
IOI terms were reported based on investigators' assessments and events were coded according to MedDRA using investigator-reported verbatim terms which mapped to specific Preferred Terms presented in the results. Instructors used the SUN criteria to grade the severity of an adverse event using.
Intraocular inflammation was defined by the following Preferred Terms [3-6]
- anterior chamber flare
- anterior chamber inflammation
- chorioretinitis
- cyclitis
- eye inflammation
- iridocyclitis
- iritis
- keratic precipitates
- keratouveitis
- non-infective chorioretinitis
- non-infectious endophthalmitis
- ocular vasculitis
- post-procedural inflammation
- retinal vasculitis
- uveitis, and
- vitritis.
Sites were queried to ensure appropriate mapping of verbatim terms to Preferred Terms.
The list of terms includes terms beyond the recognised SUN criteria for IOI to ensure a conservative approach was taken to identify any possible types of inflammation as well as rare events.
Independent review of all IOI cases
The Duke Reading Center (DRC) performed masked, independent reviews of all investigator-reported IOI cases in nAMD (TENAYA/LUCERNE) and DME (YOSEMITE/RHINE) Phase 3 studies to provide further confidence about drug safety and data robustness. Intraocular inflammation, retinal vascular changes and IOI terms reflective of clinical reporting were evaluated.[7]
The inclusion criteria comprised events of interest, including[7]
- IOI
- infectious endophthalmitis
- retinal vein occlusion and retinal artery occlusion of all severity, and
- controls.
Reviews were conducted with masked multi-modal imaging review and DRC pre-specified IOI grading variables using SD-OCT, FA, and FP.[7]
The Duke Reading Center found no stereotypical patterns or trends suggestive of IOI-associated occlusive retinal vasculitis in either the DME or nAMD trials through 2 years.[7]
