Intravitreal Carboplatin for the Treatment of Participants With Recurrent or Refractory Intraocular Retinoblastoma

"Carboplatin will be given intravitreally. Participants are eligible to receive up to 8 injections per eye (once approximately every 14 days) based on lack of toxicity and evidence of tumor response. An injection of consolidation will be given once a complete response is observed. If further regression of stable seeds is noted, additional injections (up to 8 maximum per eye) will be provided at the discretion of the treating team. Injections could be repeated if vitreous recurrence occurs from another source (and patient has not reached 8 max limit per eye)."

Maxitrol® contains neomycin and polymyxin B sulfates and dexamethasone ophthalmic suspension and is for topical ophthalmic use only. It will be given for continued use for five days following the carboplatin injection to prevent infection.

Simultaneously with intravitreal carboplatin, focal therapy will be applied as needed to eradicate the retinal source of the seeding as well as all epiretinal and subretinal active tumors at the discretion of the treating ocular oncologist.

Participants who have developed progressive disease despite focal (non-irradiative) therapy will receive brachytherapy determined by consensus between the treating ophthalmologist and radiation oncologist.
