A Study of the Drugs Selumetinib Versus Carboplatin/Vincristine in Patients With Neurofibromatosis and Low-Grade Glioma

April 9, 2026 updated by: National Cancer Institute (NCI)

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)

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. Chemotherapy drugs, 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.

Study Overview

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.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I:

INDUCTION: Patients receive carboplatin intravenously (IV) over 60 minutes on days 1, 8, 15, 22, 43, 50, 57, and 64 and vincristine IV on days 1, 8, 15, 22, 29, 36, 43, 50, 57, and 64 in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI throughout the trial.

MAINTENANCE: Patients receive carboplatin IV over 60 minutes on days 1, 8, 15, and 22 of each cycle and vincristine IV on days 1, 8, and 15 of each cycle. Cycles repeat every 6 weeks for 8 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI throughout the trial.

ARM II: Patients receive selumetinib sulfate orally (PO) twice daily (BID) on days 1-28 of each cycle. Treatment is continuous and cycles repeat every 28 days for 27 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI throughout the trial.

After completion of study treatment, patients are followed up with MRIs and physical exams every 3 months for 1 year, every 6 months for 2 years, and then once yearly for up to 10 years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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).
Baseline and end of about 12 months of treatment
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. 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.
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

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Radiographic tumor response rate
Time Frame: Assessed up to 3 years after accrual completion
Tumors will be classified into complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD). Radiologic response rates will be summarized per arm and be tested for a difference between the two arms using an exact binomial test.
Assessed up to 3 years after accrual completion
Change in VA using HOTV letter acuity testing
Time Frame: Baseline and end of about 12 months of treatment
HOTV is a recognition acuity measure. It will be conducted on patients who are developmentally able to perform this testing.
Baseline and end of about 12 months of treatment
Change in motor function
Time Frame: Baseline and approximately 12 months of treatment
The Vineland-3 Motor Scale from the Comprehensive Parent Rating Form will be used to assess motor deficits. Change in Vineland motor scale from baseline to about 12 months of treatment will be compared between two treatment arms.
Baseline and approximately 12 months of treatment
Change in quality of life (QOL)
Time Frame: Baseline and 12 months of treatment
Will be measured by Pain and Hurt subscale score. QOL will be assessed by Pediatric Quality of Life (PedsQL) Generic and Brain Tumor modules. Analysis will be based on a 2-sample t-test comparing change in Pain and Hurt subscale score from baseline to 12 months for the two arms.
Baseline and 12 months of treatment
Change in quality of life (QOL)
Time Frame: Baseline and 12 months of treatment
Will be measured by Movement and Balance subscale score. QOL will be assessed by Pediatric Quality of Life (PedsQL) Generic and Brain Tumor modules. Analysis will be based on a 2-sample t-test comparing change in Movement and Balance subscale score from baseline to 12 months for the two arms.
Baseline and 12 months of treatment
Change in executive function
Time Frame: Baseline and 24 months of treatment
Will be measured by BRIEF Cognitive Regulation Index (CRI). Executive function will be measured by age-appropriate Behavior Rating Inventory of Executive Function (BRIEF) questionnaire. Analysis will be based on a 2-sample t-test comparing change in the designated score from baseline to 24 months for the two arms.
Baseline and 24 months of treatment
Change in neurocognitive function
Time Frame: Baseline and 24 months of treatment
Will be measured by Cogstate composite score. Neurocognitive function will be measured by a computerized battery (Cogstate) testing. Analysis will be based on a 2-sample t-test comparing change in Cogstate composite score from baseline to 24 months for the two arms.
Baseline and 24 months of treatment
Overall survival (OS)
Time Frame: From randomization until death from any cause or till the time of last follow-up for patients who are alive at the time of analysis, assessed up to 3 years after accrual completion
OS is defined as the time from randomization until death from any cause or till the time of last follow-up for patients who are alive at the time of analysis. Will use the KM methods, log-rank tests, and Cox proportional hazards models to determine whether there is a difference in OS between the two arms.
From randomization until death from any cause or till the time of last follow-up for patients who are alive at the time of analysis, assessed up to 3 years after accrual completion
