Topotecan Episcleral Plaque for Treatment of Retinoblastoma

Titre officiel

Phase I Sustained-Release Topotecan Episcleral Plaque (Chemoplaque) for Retinoblastoma

Sommaire:

This single site, single-arm, non-randomized, dose escalation phase I toxicity clinical trial will assess primarily the safety and secondarily the efficacy of episcleral topotecan in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy.

Description de l'essai

Primary Outcome:

  • Maximum Tolerated Dose and Recommended Phase 2 Dose of topotecan hydrochloride administered as a Chemoplaque to pediatric patients with active Retinoblastoma.
Secondary Outcome:
  • Tumour response to the Chemoplaque as secondary therapy in eye(s) with active retinoblastoma after completion of primary standard of care treatment.
Retinoblastoma is the most common pediatric malignant intraocular tumour and originates from the retina. Treatment of eyes with advanced intraocular retinoblastoma remains a challenge. The historic standard of care for patients with unilateral disease is enucleation and for those with bilateral disease, a variety of modalities have been tried. These include radiation therapy, systemic chemotherapy, periocular administration of chemotherapy, selective intra-arterial chemotherapy, and intravitreal chemotherapy. Unfortunately, all of these modalities are associated with significant morbidity and investigators are looking for new ways to treat these patients either with novel directed drug delivery methods or with new less toxic agents. This study will evaluate the safety and efficacy of topotecan delivered directly to the eye using a novel sustained-release topotecan episcleral plaque (also referred to as a Chemoplaque) in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy. The study intervention involves the insertion and removal of the Chemoplaque, examinations under anaesthesia (EUAs), visits to clinic to monitor for adverse events throughout, and post plaque removal toxicity evaluation. EUAs, clinic visits and laboratory tests are standard of care for retinoblastoma patients.
