Brief summary
This randomized controlled trial will evaluate the effect of intravitreal faricimab or fluocinolone acetonide (FAc) intravitreal implant compared with observation on long-term visual acuity following treatment of choroidal melanoma with iodine-125 plaque brachytherapy.
Detailed description
The primary objectives are to compare long-term visual acuity outcomes in eyes that receive repeated treatment with faricimab or fluocinolone acetonide intravitreal implants with those observed initially and treated only if macular edema (ME) develops. The secondary objectives are to determine if repeated treatment with faricimab or fluocinolone acetonide intravitreal implants versus observation can prevent or alter the course of ME from radiation retinopathy and to evaluate the natural history of radiation retinopathy with multimodal imaging including widefield color photographs, widefield fluorescein angiography and OCTA.
Interventions
6.0 mg intravitreal injection at randomization and every 3 months
0.19 mg fluocinolone acetonide intravitreal implant (Iluvien) at randomization and at 24 months

Eligibility
Inclusion criteria
Key Inclusion Criteria * Primary uveal melanoma (excluding iris melanoma) receiving primary treatment with plaque brachytherapy * Absence of unrelated cause of visual loss * Baseline visual acuity ≥ 34 letters (20/200 Snellen equivalent or better) * Posterior tumor margin \>0 mm from the center of the macula (i.e., tumor is NOT under the geometric center of the fovea) * Posterior tumor margin \>0 mm from the closest disc margin (i.e., tumor is not touching the edge of the optic disc) * Calculated total dose to center of the macula ≥30 Gy Key
Exclusion criteria
* Opaque media * Inability to undergo fluorescein angiography * Less than 18 years of age * Prior vitrectomy * Intraocular pressure (IOP) ≥ 25 mmHg or history of steroid- induced IOP elevation that required treatment at baseline * IOP ≥ 25 mmHg at randomization or increase in IOP ≥ 8 mmHg from baseline to randomization (following steroid challenge
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in visual acuity from baseline | from baseline at 3 years | Visual acuity is measured as a continuous integer letter score from 0 to 100, with higher numbers indicating better visual acuity. A letter score of 85 is approximately 20/20 and a letter score of 70 is approximately 20/40, the legal unrestricted driving limit in most states. A 5-letter change for an individual is approximately equal to a 1-line change on a vision chart. |
| Loss of 15 or more letters of visual acuity from baseline | from baseline at 3 years | Visual acuity is measured as a continuous integer letter score from 0 to 100, with higher numbers indicating better visual acuity. A letter score of 85 is approximately 20/20 and a letter score of 70 is approximately 20/40, the legal unrestricted driving limit in most states. A 5-letter change for an individual is approximately equal to a 1-line change on a vision chart. |
