Conditions

Unilateral Retinoblastoma

Brief summary

This pilot clinical trial studies whether unilateral group D retinoblastoma, or retinoblastoma affecting one eye that has spread to the inner jelly like part of the eye, can be treated with a new technique for delivering chemotherapy directly into the blood vessel that supplies the affected eye. This new technique is called intra-arterial injection. Giving melphalan via intra-arterial injection may make it less likely that children will need surgery to remove the eye and may reduce the amount of treatment side effects.

Detailed description

PRIMARY OBJECTIVES: I. To study the feasibility of delivering melphalan directly into the ophthalmic artery in children with newly diagnosed unilateral group D retinoblastoma, who would otherwise be considered for enucleation. SECONDARY OBJECTIVES: I. To estimate the ocular salvage rate after treatment with intra-arterial melphalan in children with newly diagnosed unilateral retinoblastoma with group D disease. II. To evaluate the toxicities and adverse events associated with delivering multiple doses of intra-arterial chemotherapy. III. To evaluate vision outcomes in children treated with intra-arterial chemotherapy. IV. To monitor the rate of the development of metastatic disease while on protocol therapy. TERTIARY OBJECTIVES: I. To evaluate the effects of intra-arterial therapy on the histopathology of eyes enucleated for progression. OUTLINE: Patients receive melphalan intra-arterially (IA) on day 1. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then periodically for 2 years.

Design outcomes

Primary

MeasureTime frameDescription
Number of Patients Experiencing Feasibility FailureUp to 4 monthsFeasibility failure is defined as a) interventional radiologist is unable to access the ophthalmic artery for the 1st chemotherapy administration for any reason; b) patient develops central retinal artery occlusion after the 1st or 2nd course that does not reopen by the time the next injection is due; or c) the patient cannot receive all three treatments because of Common Terminology Criteria for Adverse Events (CTCAE) complications grade III or IV that are considered possibly, probably or likely related treatment.

Secondary

MeasureTime frameDescription
Incidence of Grade 3 or Higher CTCAE Adverse Events Associated With Multiple Doses of IA ChemotherapyUp to 30 days after completion of study treatmentThe percentage of patients with at least 1 occurrence of grade 3 or higher CTCAE adverse experience will be provided. Ineligible patients or patients who do not receive any protocol therapy are excluded from reporting of adverse events.
