Current Primary Outcome Measures  ICMJE
 (submitted: December 11, 2019)
  • Event-free survival (EFS) [ Time Frame: From randomization to the first occurrence of any of the following events: clinical or radiographic disease progression, disease recurrence, second malignant neoplasm, or death from any cause, assessed up to 3 years after accrual completion ]
    EFS is defined as time from randomization to the first occurrence of any of the following events: clinical or radiographic disease progression, disease recurrence, second malignant neoplasm, or death from any cause. Patients who are event-free will be censored at the time of last follow-up. Hazard ratio based on a stratified Cox proportional hazards model will be reported, along with a 90% confidence interval.
  • Number of participants with visual acuity (VA) improvement per arm [ Time Frame: Baseline and end of about 12 months of treatment ]
    VA will be assessed using Teller acuity cards (TAC). A significant improvement in VA will be defined as a decrease of >= 0.2 logMAR (corrected for age) from baseline (pre-treatment baseline) to end of about 12 months of treatment. The primary analysis will be based on per subject outcome (rather than per eye).
Original Primary Outcome Measures  ICMJE
 (submitted: March 11, 2019)
  • Event-free survival [ Time Frame: From randomization to the first occurrence of any of the following events: clinical or radiographic disease progression, disease recurrence, second malignant neoplasm, or death from any cause, assessed up to 10 years ]
    Will estimate the hazard ratio based on a stratified Cox proportional hazards model and use Kaplan-Meier (KM) methods to visualize and summarize the data.
  • Visual acuity (VA) [ Time Frame: Up to 12 cycles ]
    Defined as the difference in proportion of randomized patients in each arm who experience an improvement in VA within the first 12 cycles of treatment (approximately 1 year). Assessed using Teller acuity cards (TAC). The primary analysis will be based on per subject outcome (rather than per eye). For the per subject analysis, will use an exact binomial test to compare the difference in the proportion of subjects in each arm that show improvement in VA within 12 months of treatment using a 1 sided test with 5% type 1 error.

Descriptive Information
Brief Title  ICMJE A Study of the Drugs Selumetinib Versus Carboplatin/Vincristine in Patients With Neurofibromatosis and Low-Grade Glioma
Official Title  ICMJE A Phase 3 Randomized Study of Selumetinib Versus Carboplatin/Vincristine in Newly Diagnosed or Previously Untreated Neurofibromatosis Type 1 (NF1) Associated Low-Grade Glioma (LGG)
Brief Summary This phase III trial studies if selumetinib works just as well as the standard treatment with carboplatin/vincristine (CV) for subjects with NF1-associated low grade glioma (LGG), and to see if selumetinib is better than CV in improving vision in subjects with LGG of the optic pathway (vision nerves). Selumetinib is a drug that works by blocking some enzymes that low-grade glioma tumor cells need for their growth. This results in killing tumor cells. Drugs used as chemotherapy, such as carboplatin and vincristine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether selumetinib works better in treating patients with NF1-associated low-grade glioma compared to standard therapy with carboplatin and vincristine.
Detailed Description

PRIMARY OBJECTIVES:

I. To determine whether the efficacy of treatment with selumetinib sulfate (selumetinib) as measured by event-free survival (EFS) is non-inferior to treatment with carboplatin/vincristine sulfate (vincristine) (CV) in previously untreated neurofibromatosis type 1 (NF1)-associated low-grade glioma (LGG).

II. To determine whether visual acuity (VA) using Teller acuity cards (TAC), in patients with NF1-associated LGG within the optic pathway, is better in those treated with selumetinib compared to CV.

SECONDARY OBJECTIVES:

I. To estimate tumor response rates and overall survival (OS) in each treatment regimen in previously untreated NF1-associated LGG.

II. To evaluate VA outcomes utilizing HOTV letter acuity testing in previously untreated NF1-associated LGG within the optic pathway in patients who are old enough to perform visual acuity testing utilizing HOTV (a recognition acuity measure).

III. To describe the improvement in motor function as measured by the Vineland scale in patients with previously untreated NF1-associated LGG that have documented motor deficits at enrollment.

IV. To prospectively evaluate and compare the quality of life among patients treated with selumetinib or CV.

V. To prospectively evaluate and compare the cognitive, social, emotional, and behavioral functioning of patients with NF1-associated LGG treated with either selumetinib or CV.

EXPLORATORY OBJECTIVES:

I. To evaluate optical coherence tomography (OCT) measures of retinal axon and ganglion cell thickness as a marker of treatment response in previously untreated NF1-associated LGG within the optic pathway.

II. To compare novel, semi-automated volumetric magnetic resonance imaging (MRI) measures to traditional measurements of treatment response (bi-dimensional MRI measurements) in NF1-associated optic pathway tumors.

III. To obtain paired blood and tumor tissue to be banked for future NF1-LGG biology studies involving comprehensive molecular analysis, including but not limited to whole exome and ribonucleic acid (RNA) sequencing.
