Brief description of study

What is the purpose of this study?
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 BRAFV600Eutation 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 tumorher by killing the cells or by stopping them from dividing. The overall goal ofhis study is to see if selumetinib works just as well as the standard treatment of CV forwith 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 alsowith selumetinib improves the quality of life for subjects who take it.
 
THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study

What will happen during the study?
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 baselined end of induction.
MAINTENANCE: Patients receive vincristine sulfate IV over 1 minute on days 1, 8, and 15, andboplatin 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 duringw 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,hroughout the trial, and during follow up.
After completion of study treatment, patients are followed up every 3 months for year 1,very 6 months for years 2-3, and then annually for years 4-10.
