Spots Global Cancer Trial Database for A Study of the Drugs Selumetinib vs. Carboplatin and Vincristine in Patients With Low-Grade Glioma

Study Description

Brief Summary: This phase III trial compares the effect of selumetinib versus the standard of care treatment with carboplatin and vincristine (CV) in treating patients with newly diagnosed or previously untreated low-grade glioma (LGG) that does not have a genetic abnormality called BRAFV600E mutation and is not associated with systemic neurofibromatosis type 1. Selumetinib works by blocking some of the enzymes needed for cell growth and may kill tumor cells. Carboplatin and vincristine are chemotherapy drugs that work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. The overall goal of this study is to see if selumetinib works just as well as the standard treatment of CV for patients with LGG. Another goal of this study is to compare the effects of selumetinib versus CV in subjects with LGG to find out which is better. Additionally, this trial will also examine if treatment with selumetinib improves the quality of life for subjects who take it.

Detailed Description: PRIMARY OBJECTIVE: I. To demonstrate that the efficacy of treatment with selumetinib as measured by event-free survival (EFS) is non-inferior compared to treatment with carboplatin/vincristine (CV) in previously-untreated low-grade glioma (LGG) not associated with BRAFV600E mutations or systemic neurofibromatosis type 1 (NF1). SECONDARY OBJECTIVES: I. To estimate tumor response rates to each regimen of chemotherapy. II. To evaluate visual acuity (VA) outcomes utilizing Teller Acuity Cards (TAC) and HOTV letter acuity testing in previously-untreated optic pathway gliomas (OPGs). III. To describe the improvement in motor function as measured by the Vineland Scale in children with previously-untreated LGG that have motor deficits at enrollment. IV. To estimate the difference in EFS and tumor response rate between BRAF rearranged and non-BRAF rearranged patients treated on each chemotherapy regimen. V. To prospectively evaluate the quality of life of children with LGG not associated with BRAFV600E or systemic NF1 treated with either CV or selumetinib. VI. To prospectively evaluate the cognitive, social, emotional, and behavioral functioning of children with LGG not associated with BRAFV600E or systemic NF1 treated with either CV or selumetinib. EXPLORATORY OBJECTIVE: I. To obtain paired blood and tumor specimens for future biology studies, including studies to correlate genomic drivers to response. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: INDUCTION: Patients receive vincristine sulfate intravenously (IV) over 1 minute on days 1, 8, 15, 22, 29, 36, 43, 50, 57, and 64, and carboplatin IV over 60 minutes on days 1, 8, 15, 22, 43, 50, 57, and 64 in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood and magnetic resonance imaging (MRI) at baseline and end of induction. MAINTENANCE: Patients receive vincristine sulfate IV over 1 minute on days 1, 8, and 15, and carboplatin IV over 60 minutes on days 1, 8, 15, and 22. Treatment repeats every 42 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood and undergo MRI at baseline, throughout the trial, and during follow up. ARM II: Patients receive selumetinib sulfate orally (PO) twice daily (BID) on days 1-28. Treatment repeats every 28 days for up to 27 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood and undergo MRI at baseline, throughout the trial, and during follow up. After completion of study treatment, patients are followed up every 3 months for year 1, every 6 months for years 2-3, and then annually for years 4-10.
