Combination Chemotherapy and Cyclosporine Followed by Focal Therapy for Bilateral Retinoblastoma

Study Purpose

RATIONALE: Drugs used in chemotherapy, such as carboplatin, etoposide, and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sometimes when chemotherapy is given, it does not stop the growth of tumor cells. The tumor is said to be resistant to chemotherapy. Giving cyclosporine together with chemotherapy may reduce drug resistance and allow the tumor cells to be killed. Cryotherapy kills tumor cells by freezing them. Laser therapy uses light to kill tumor cells. Giving combination chemotherapy together with cyclosporine followed by cryotherapy and/or laser therapy may be an effective treatment for retinoblastoma. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with cyclosporine followed by cryotherapy and/or laser therapy works in treating patients with newly diagnosed retinoblastoma in both eyes.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT00110110
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Phase 2

Additional Details

OBJECTIVES: Primary.

  • - Compare the efficacy of neoadjuvant high-dose carboplatin and etoposide, vincristine, and cyclosporine (CSA) followed by ophthalmic focal therapy comprising cryotherapy and/or laser therapy to historical world data of chemotherapy treatment without CSA, in terms of increasing the proportion of eyes that remain relapse free and do not require external beam radiotherapy and/or enucleation, in patients with newly diagnosed Group B, C, or D bilateral intraocular retinoblastoma.
Secondary.
  • - Determine the toxicity of this regimen in these patients.
OUTLINE: This is a multicenter study. Patients receive high-dose carboplatin IV over 30 minutes on day 1; vincristine IV over 5 minutes and high-dose etoposide IV over 25 minutes on day 2; cyclosporine IV over 1 hour before chemotherapy and then over 2 hours after chemotherapy on days 1 and 2, and filgrastim (G-CSF) subcutaneously once daily beginning on day 3 and continuing until day 16 or until blood counts recover. Treatment repeats every 21 days for a total of 3 courses for patients with Group B disease and a total of 6 courses for patients with Group C or D disease. Patients undergo eye examination under anesthesia (EUA) at initial staging and then before each course of chemotherapy. Patients with small peripheral tumors in eyes without retinal detachment undergo minimal focal therapy (mainly cryotherapy) during EUA at initial staging and then after chemotherapy courses 1 and 2. At EUA after the third and subsequent courses of chemotherapy, patients with tumors that have sufficiently reduced in size undergo additional cryotherapy or laser therapy. After completion of chemotherapy, patients with any suspicious, active, or reactivated tumor undergo additional cryotherapy and/or laser therapy during EUA approximately every 4-8 weeks (or at longer intervals) for up to 5 years (as needed). After completion of study chemotherapy, patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually for 1 year. PROJECTED ACCRUAL: A total of 71 patients will be accrued for this study within 2.4 years.

Arms & Interventions

Arms

Experimental: CEV Chemo + Cyclosporine & Focal Therapy

Systemic carboplatin (28 mg/kg/dose), etoposide (12 mg/kg/dose) and vincristine sulfate (0.025 mg/kg/dose for the first cycle and 0.05 mg/kg/dose for subsequent cycles if first cycle well-tolerated) chemotherapy given with cyclosporin A (33 mg/kg/dose). Following 4-6 cycles CEV chemotherapy (depending on tumor stage) given every 3 weeks, focal laser therapy and/or cryosurgery are applied for tumor consolidation. Filgrastim is given after each chemotherapy cycle to prevent severe neutropenia.
