Study Description
Brief Summary:

This study will test if giving topotecan directly into the blood vessel of the eye will improve the treatment of retinoblastoma. This method is referred to as "selective intra-ophthalmic artery chemotherapy" (SIOAC).

The goals of this study are:

  • To find out if topotecan is an effective treatment for retinoblastoma when delivered directly to the ophthalmic artery (SIOAC delivery)
  • To find out what kind of effects (good and bad) can be expected when topotecan is given by SIOAC
  • To assess visual pathway function before and after the study therapy
  • To learn more about the pharmacology (how your body handles the drug) of topotecan when delivered directly to the ophthalmic artery

Arm Intervention/treatment
Experimental: Treatment of Retinoblastoma
Study of Intra-Ophthalmic Artery Topotecan infusion for the Treatment of Retinoblastoma.

Outcome Measures

Primary Outcome Measures :
  1. 1-year event-free survival (event defined as the need for external beam radiation or enucleation) [ Time Frame: 1 year ]
  2. Response rate of retinoblastoma to topotecan when administered directly into the ophthalmic artery. [ Time Frame: Up to 18 weeks ]
    EUA and retCAM imaging will be used to assess response rate.

  3. Local (ocular) toxicities associated with the proposed regimen. Toxicities assessed using clinical examinations (EUA and Teller cards and Allan figures or Snellen visual acuity charts or other measures as appropriate for child's age.) [ Time Frame: Up to 12 months ]
    1. For non-verbal infants we will employ Teller cards or Reacts to Light (if vision is too poor for Teller cards)
    2. For pre-school age verbal toddlers/children we will employ LEA Symbols or HOTV, and possibly Allen figures
    3. For older children capable of reading an alphabet we will employ Snellen visual acuity charts. Standard methods to assess color vision will also be employed when feasible.

  4. Patterns of response of retinoblastoma to topotecan when administered directly into the ophthalmic artery. [ Time Frame: Up to 18 weeks ]
    Physical examination of the tumors will be recorded at baseline and at every tumor assessment visit. Tumors will be classified as having Type I, II, III, IV, V or O response based on characteristic features identified during physical examination.

Secondary Outcome Measures :
  1. Visual pathway function [ Time Frame: Up to 12 months ]
    Evaluation of visual pathway function will be measured using visual acuity, electroretinogram, visual evoked potential, and functional magnetic resonance imaging.

  2. Pharmacokinetics (Cmax and AUC) of topotecan when administered directly into the ophthalmic artery. [ Time Frame: Samples taken 15 and 60 minutes after topotecan administration on Day 1 of Cycle 1 (optional for patients) ]
  3. Histologic findings in the eyes ultimately requiring enucleation. [ Time Frame: At time of enucleation, only if indicated ]
    Any eye requiring enucleation will be assessed for the presence or absence of 'high risk' features defined as scleral or massive choroidal invasion of viable tumor, anterior chamber involvement, invasion of the optic nerve posterior to the lamina cribrosa, ciliary body or iris invasion.

Ages Eligible for Study:   up to 15 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Age: 15 years of age or younger
  2. Diagnosis: Patients with untreated Group C/D/E unilateral Retinoblastoma at presentation without an indication for immediate enucleation (neovascular glaucoma or orbital pain) (Stratum A), or patients with a history of bilateral retinoblastoma and recurrent and/or refractory intraocular retinoblastoma where chemotherapy, external beam radiation and/or enucleation remain the only known option for disease control (Stratum B).
  3. Therapeutic Options: Chemotherapy, External Beam Radiation therapy and/or Enucleation
  4. Lansky ≥ 50 for patients ≤ 10 years of age; Karnofsky ≥ 50 for patients > 10 years of age. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
  5. Prior Therapy: Stratum A: No prior therapy is allowed. Stratum B: Patients must have local relapsed/refractory disease after receiving standard upfront therapy involving at least one chemotherapeutic regimen. There is no limit to prior chemotherapeutic regimens permitted. Prior radiation therapy is permitted.
  6. Patients must have recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study, as described below:

    • Myelosuppressive chemotherapy: patients must not have received myelosuppressive chemotherapy within 3 weeks of study enrollment.
    • Biologic therapies: Patients must not have received biologic anti-cancer agents within one week of study enrollment.
    • Radiation therapy: Four weeks must have elapsed since external beam radiation therapy, if given.
  7. Adequate Bone Marrow Function Defined as:

    • Peripheral absolute neutrophil count (ANC) greater than or equal to 750/uL
