Ocular Conservative Treatment for Retinoblastoma : Efficacy of the New Management Strategies and Visual Outcome

Recruiting now · Phase 2/Phase 3

Conditions studied: Retinoblastoma

In brief

This protocol includes 2 independent studies. Both studies are multicenter studies, evaluating different therapeutic approaches in two different populations of patients: * Study 1, a randomized phase-II study evaluating the efficacy of Intra-Arterial Chemotherapy (IAC) with melphalan and topotecan versus melphalan alone, both in association with ophthalmologic treatments. * Study 2, a minimally invasive interventional study evaluating the results on visual function following reference treatment with intravenous (IV) chemotherapy in association with ophthalmologic or local ophthalmological treatment without IV chemotherapy.

You may qualify if…

• Overall study inclusion criteria:
• Newly diagnosed retinoblastoma (RB).
• Retinoblastoma with at least one eye eligible for conservative management.
• Patients likely to be compliant with the study requirements and visits, including late follow-up.

• Study 1 inclusion criteria:
• 1. Children aged from 6 months to 6 years. 9. Retinoblastoma in at least one eye, deemed manageable with IAC in one side and without IV chemotherapy:
• Unilateral Retinoblastoma classified as group B, C (if vitreous seeds < 3 mm), D or E with no invasion of the anterior segment, and without massive tumor of more than 2/3 of the eye, eligible for conservative management, or
• Bilateral Retinoblastoma but with very unbalanced lesions between the two eyes: one eye group D or E without invasion of the anterior segment or massive tumor of more than 2/3 of the eye, eligible for IAC, and the other eye eligible for local treatment only (without IAC).
• Study 2 inclusion criteria:
• 2. Retinoblastoma eligible for conservative management although not manageable with IAC:
• Unilateral Retinoblastoma in children below 6 months of age, classified as Group A, B, C or D, with or without vitreous seeding, compatible with conservative management, or
• Bilateral Retinoblastoma classified as group A, B, C D, or E without invasion of the anterior segment, and/or massive tumors of more than 2/3 of the eye and eligible for conservative management.

You may not qualify if…

• Overall study non-inclusion criteria:
• RB not eligible for conservative management :
• Extra-ocular extension of the disease, or
• Group E eyes with invasion of the anterior segment, and/or massive tumors of more than 2/3 of the eye.
• Patient older than 6 years of age.
• Patients with another associated disease contra indicating systemic chemotherapy.
• Previously treated retinoblastoma by chemotherapy.
• Patients already treated for another malignant disease.
• Patient with any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule.
• Patients whose parents have not accepted the treatment regimen after explanation of it.
• Contraindication to study drug mentioned in SmPC (Summary of Products Characteristics) of the study drugs.
• Inclusion in another experimental anti-cancer drug therapy.
• Study 1 non-inclusion criteria:
