OBJECTIVES: Primary * Determine the feasibility and toxicity of an induction and maintenance regimen comprising carboplatin, vincristine, and temozolomide in children with progressive and/or symptomatic low-grade gliomas. Secondary * Determine response rate in patients treated with this regimen. * Determine 3-year progression-free survival and overall survival of patients treated with this regimen. * Correlate response and progression-free survival with the genomic profile of tumors in patients treated with this regimen. OUTLINE: This is a pilot study. * Induction therapy: Patients receive carboplatin IV over 1 hour on days 1, 8, 15, and 22; vincristine IV on days 1, 8, 15, 22, 29, and 36; and oral temozolomide on days 43-47. Four weeks after the completion of induction therapy, patients achieving stable or responding disease proceed to maintenance therapy. * Maintenance therapy: Patients receive carboplatin and temozolomide as in induction therapy and vincristine IV on days 1, 8, and 15. Treatment repeats every 10 weeks for a total of 6 courses in the absence of disease progression. Patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter. PROJECTED ACCRUAL: A total of 30-50 patients will be accrued for this study within 2 years.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
66 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Treatment Groups
Group I
Experimental
Induction therapy: Patients receive carboplatin IV (175/m2) over 1 hour on days 1, 8, 15, and 22; vincristine IV (1.5 mg/m2) on days 1, 8, 15, 22, 29, and 36; and oral temozolomide (200 mg/m2) on days 43-47. Four weeks after the completion of induction therapy, patients achieving stable or responding disease proceed to maintenance therapy. Maintenance therapy: Patients receive carboplatin (175/m2) and temozolomide (200 mg/m2) as in induction therapy and vincristine IV ((1.5 mg/m2) day 1 of weeks 10,11,12. Treatment repeats every 10 weeks for a total of 6 courses in the absence of disease progression.

Study Objectives
Primary Objectives

Success is defined as the completion of induction plus one cycle of maintenance within 24 weeks of enrollment without more than a 25% reduction in either carboplatin or temozolomide dosage. Failure to complete the induction and one cycle of maintenance within 24 weeks counts as a short-term-feasibility failure.

Success is defined as the completion of induction plus four cycles of maintenance within 60 weeks of enrollment without more than a 25% reduction in either carboplatin or temozolomide dosage. If the participant completes all therapy within 60 weeks the patient is a long-term feasibility success. As such, a patient who experiences short term feasibility failure can be classified as a long-term feasibility success.
Secondary Objectives

Primary safety endpoints are (1) the occurrence of toxic death, which is death during treatment that is not primarily attributable to disease progression, and (2) the occurrence of grade 4 allergy to carboplatin.

Occurence of grade 3 or 4 thrombocytopenia or neutropenia while receiving protocol therapy.

Percentage probability of being alive and without the occurrence of disease progression 3 years following enrollment.

Percentage probability of being alive and without the occurrence of disease progression or second malignant neoplasm 6 years following enrollment.

Response as complete response, partial response, stable disease, or progressive disease using three-dimensional imaging measurements (preferable) or two-dimensional imaging measurements, as well as the response in the context of multiple lesions or disseminated disease.
