Een studie om de behandeling met alleen het geneesmiddel Selumetinib versus Selumetinib en vinblastine te vergelijken bij patiënten met recidiverend of progressief laaggradig glioom
Een fase 3-onderzoek van Selumetinib (NSC# 748727) of Selumetinib in combinatie met vinblastine voor niet-NF1, niet-TSC-patiënten met recidiverende of progressieve laaggradige gliomen (LGG's) zonder BRAFV600E- of IDH1-mutaties
This phase III trial investigates the best dose of vinblastine in combination with selumetinib and the benefit of adding vinblastine to selumetinib compared to selumetinib alone in treating children and young adults with low-grade glioma (a common type of brain cancer) that has come back after prior treatment (recurrent) or does not respond to therapy (progressive). Selumetinib is a drug that works by blocking a protein that lets tumor cells grow without stopping. Vinblastine blocks cell growth by stopping cell division and may kill cancer cells. Giving selumetinib in combination with vinblastine may work better than selumetinib alone in treating recurrent or progressive low-grade glioma.

PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of selumetinib sulfate (selumetinib) + vinblastine sulfate (vinblastine) for children with progressive or recurrent low-grade gliomas (LGGs).
II. To determine if selumetinib + vinblastine will lead to improved event-free survival (EFS) outcome compared with selumetinib alone for children with progressive or recurrent LGGs.
SECONDARY OBJECTIVES:
I. To estimate the objective response rates and overall survival associated with treatment with selumetinib + vinblastine versus single-agent selumetinib.
II. To estimate the difference in EFS and response rate between patients with BRAF rearranged LGG and patients with non-BRAF rearranged LGG after treatment with selumetinib + vinblastine versus single-agent selumetinib.
III. To evaluate toxicities associated with selumetinib + vinblastine and single-agent selumetinib for children with progressive or recurrent LGGs.
IV. To compare the quality of life among patients treated with selumetinib + vinblastine and single-agent selumetinib.
V. To examine the vision outcomes among patients with optic pathway gliomas (OPGs) treated with selumetinib + vinblastine and single-agent selumetinib.
EXPLORATORY OBJECTIVE:
I. To obtain paired blood and tumor specimens for future biology studies, including studies to correlate genomic drivers to response.
OUTLINE: This is a dose-escalation feasibility study of vinblastine sulfate in combination with selumetinib, followed by a randomized efficacy study. Patients in the feasibility study are assigned to Arm I, while patients in the efficacy study are randomized to Arm I or Arm II.
ARM I: Patients receive vinblastine sulfate intravenously (IV) on days 1, 8, 15, and 22 and selumetinib sulfate orally (PO) twice daily (BID) on days 1-28. Treatment repeats every 28 days. Patients receive selumetinib and vinblastine for a total duration of 17 cycles followed by 10 additional cycles of selumetinib alone in the absence of disease progression or unacceptable toxicity. Patients undergo magnetic resonance imaging (MRI) throughout the trial. Patients also undergo blood sample collection during screening and on study.
ARM II: Patients receive selumetinib sulfate PO 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 undergo MRI throughout the trial. Patients also undergo blood sample collection during screening and on study.
After completion of study treatment, patients are followed up every 3 months for year 1, every 6 months for years 2-3, and annually for years 4-5.

The MTD is empirically defined as the highest dose level at which 6 patients have been treated with at most one patient experiencing a dose-limiting toxicity and the next higher dose level has been determined to be too toxic. |
1 month post enrollment

Event-free survival (EFS) (efficacy)
Tijdsspanne: Up to 5 years after enrollment
|
Will use Kaplan-Meier (KM) methods and stratified log-rank tests to estimate EFS per arm and compare the EFS outcome between the two arms to assess difference in efficacy. EFS is defined as the interval from randomization to the first occurrence of clinical or radiographic disease progression, disease recurrence, subsequent malignant neoplasm, or death from any cause. Patients who are event-free will be censored at the time of last follow-up. |

Radiographic tumor response rate (efficacy)
Tijdsspanne: Up to 2 years after enrollment
