About this study

Official title: Trial of Systemic Neoadjuvant Chemotherapy for Group B Intraocular Retinoblastoma

This phase III trial is studying how well giving carboplatin and vincristine together with standard local ophthalmic therapy works in treating children with intraocular retinoblastoma. Drugs used in chemotherapy, such as carboplatin and vincristine, work in different ways to stop tumor from dividing so they stop growing or die. It is not yet known whether neoadjuvant chemotherapy combined with standard local ophthalmic therapy is effective in treating intraocular retinoblastoma.

Read the detailed description

PRIMARY OBJECTIVES:

  1. Determine the 2-year event-free survival of patients with Group B intraocular retinoblastoma treated with neoadjuvant chemoreduction comprising carboplatin and vincristine and standardized local ophthalmic therapy.

SECONDARY OBJECTIVES:

  1. Determine the response rate after one course of chemoreduction (before standardized local ophthalmic therapy) in these patients.

II. Correlate response rate with event-free survival in patients treated with this regimen.

III. Determine the incidence of toxic effects in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive chemoreduction comprising carboplatin IV over 60 minutes followed by vincristine IV over 1-2 minutes on day 1. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. After the first course of chemoreduction, patients undergo standardized local ophthalmic therapy comprising local laser therapy, cryotherapy, and/or radioactive plaque comprising iodine I 125 or ruthenium Ru 106.

Patients are followed every 3-4 weeks until there is no active tumor seen on a minimum of 3 ophthalmic exams under anesthesia, every 6-8 weeks until 3 years of age, every 4-6 months until 10 years of age, and then annually thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Event-free Survival

    Proportion of patients with event free survival at 2 years. An event is defined as the need for non-protocol therapy, defined as additional on-protocol chemotherapy, enucleation or external beam radiation, among patients with Group B intraocular tumors with a schedule of neoadjuvant 2-agent (Vincristine/Carboplatin) chemotherapy (chemo-reduction) and standardized local ophthalmic therapy.

    Measured: At 2 years

Secondary outcomes (4)
  1. Response Rate (RR) at Patient Level After the First Course of Therapy

    RR will be estimated. The response after 1 course of chemotherapy will be used to better define response to this neoadjuvant systemic chemotherapy, prior to the use of local ophthalmic therapy. Response to subsequent courses will help define response to combined systemic chemotherapy and local ophthalmic therapy. Number of patients with Type I, II, III or IV response after first course of therapy

    Measured: 1 month after enrollment

  2. Response Rate (RR) at Eye Levels After the First Course of Therapy

    RR will be estimated. The response after 1 course of chemotherapy will be used to better define response to this neoadjuvant systemic chemotherapy, prior to the use of local ophthalmic therapy. Response to subsequent courses will help define response to combined systemic chemotherapy and local ophthalmic therapy. Number eyes with Type I, II, III or IV response after first course of therapy

    Measured: 1 month after enrollment

  3. Event-free Survival Rate (EFSR) Defined as the Need for Non-protocol Chemotherapy, Enucleation, or EBRT at the Patient Level

    EFSR will be estimated for patients who respond to vincristine and carboplatin after an initial 1 cycle of chemoreduction

    Measured: 2 years after enrollment

  4. Toxicity as Assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0

    Participants with Grade 3 and higher reported on protocol therapy

    Measured: 6 months after enrollment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Carboplatin, Cryosurgery and Infrared Laser Therapy in people with Intraocular Retinoblastoma, run by Children's Oncology Group at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 37 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Event-free Survival (time frame: At 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2023.
