What is the purpose of this trial?

This trial tests whether the chemotherapy drug carboplatin alone can treat low-grade glioma (a type of brain tumor) as effectively as the usual combination of carboplatin and vincristine. The goal is to determine if carboplatin alone can maintain treatment success while improving the quality of life for patients and their families. This trial focuses on individuals under 21 with a low-grade glioma who have not started other treatments besides surgery or steroids. As a Phase 3 trial, it represents the final step before FDA approval, offering patients a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot be on any other investigational or chemotherapy drugs. If you are taking those, you would need to stop.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that carboplatin, whether used alone or with vincristine, is generally safe, though side effects can occur. In studies where carboplatin was combined with vincristine to treat children with low-grade brain tumors, many patients experienced positive outcomes. However, some faced side effects like low blood cell counts, increasing the risk of infections or bruising.

Carboplatin alone has also been studied for various brain tumors. It is considered somewhat effective and generally safe, but like many cancer treatments, it can cause side effects, such as changes in blood cell levels. Doctors closely monitor this during treatment.

Both treatments have been tested in many patients, and while side effects can occur, they are usually manageable. It's important to discuss with a healthcare provider what to expect and how to handle any possible side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for brain tumors because they offer unique approaches compared to traditional options. The combination of Carboplatin and Vincristine provides an aggressive regimen with a structured induction and maintenance phase, potentially increasing efficacy through its dual-drug strategy. On the other hand, the Carboplatin-alone treatment delivers a higher dosage less frequently, which might reduce side effects and improve patient quality of life. Both approaches aim to target cancer cells more effectively and could lead to better outcomes for patients.

What evidence suggests that carboplatin alone could be an effective treatment for low grade glioma?

Research has shown that using carboplatin and vincristine together effectively treats low-grade gliomas, a type of brain tumor, in children. This combination excels at controlling these tumors and improving survival rates. In this trial, one group of participants will receive this combination treatment. Another group will receive carboplatin alone, which has also shown promise, as studies indicate it can manage these tumors well. Early results suggest that carboplatin alone might be as effective as the combination treatment. Both approaches in this trial aim to manage the condition effectively, with ongoing research to understand their effects on quality of life. ^{1 4 5 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Carboplatin
• Vincristine

Trial Overview

The study compares two treatments: the standard therapy of carboplatin plus vincristine versus just carboplatin alone. It aims to see if carboplatin by itself can effectively treat low grade gliomas while possibly improving patients' quality of life.

How Is the Trial Designed?

Group I: Carboplatin alone Experimental Treatment 2 Interventions

Carboplatin is given once every four weeks, Each 4-week period is considered a cycle. Regimen B will last for 13 cycles which is equivalent to one year (52 weeks). Carboplatin 560 mg/m2 (or 19 mg/kg for children weighing less than 12 kg) IV over 1 hour every 4 weeks

Group II: Carboplatine and Vincristine Active Control 2 Interventions

Induction: 10 weeks of Carboplatin and Vincristine therapy. Carboplatin 175 mg/m2 give an an IV infusion weeks 1, 2, 3, 4, 7, 8, 9, 10. Vincristine 1.5mg/m2 (0.05 mg/kg if child less than 12 kg) (maximum dose 2.0 mg) give as an IV bolus infusion on weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Maintenance: Maintenance consists of 8, 6-week cycles of chemotherapy. It begins week 12 of Induction or when peripheral counts recover with ANC \>1,000/µL and platelet count \>100,000/µL. Each cycle will consist of 4 weekly doses of carboplatin, three weekly doses of vincristine (given concomitantly with the first 3 weeks of carboplatin), followed by two weeks of rest for a total of 6 weeks. Maintenance will continue for a total of 8 cycles. Carboplatin 175 mg/m2 as an IV continuous infusion over 60 minutes on Week 1, 2, 3, 4 of each cycle. Vincristine 1.5 mg/m2 (0.05 mg/ kg for children \<12 kg) (maximum dose 2.0 mg) IV bolus infusion on Week 1, 2, 3 of each cycle.
