What is the purpose of this trial?

This trial aims to create personalized treatment plans for individuals with relapsed medulloblastoma or ependymoma, two types of brain tumors. Researchers will analyze tumor samples to identify the best combination of up to four existing drugs tailored to each person's unique tumor profile. This approach is called the Specialized Tumor Board Treatment Plan. The goal is to offer the most effective and least harmful treatment options. Ideal participants are children and young adults who have experienced their first or second relapse and have tumors that can be surgically accessed.

As an unphased trial, participants can contribute to pioneering research that may lead to more personalized and effective treatments.

Do I need to stop my current medications for the trial?

The trial protocol does not specify if you need to stop all current medications, but you must have stopped any anti-cancer treatments and recovered from their effects before joining. It's best to discuss your specific medications with the study team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that the safety of the Specialized Tumor Board Treatment Plan remains under investigation. This plan uses up to four FDA-approved drugs, selected based on each patient's tumor specifics. Although approved for other uses, the combined effects of these drugs in this context are still under study.

Previous studies have examined the effectiveness and safety of these treatments for children and young adults with recurring medulloblastoma and ependymoma. The goal is to identify both benefits and potential side effects. By personalizing treatments in real-time, the researchers aim to discover the most effective and least harmful options.

Currently, safety information updates as more data is collected. Early assessments have not revealed any severe unexpected side effects, but ongoing monitoring remains essential. This promising approach of customizing treatment for each person involves some unknowns that this trial seeks to explore. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this treatment for medulloblastoma because it offers a personalized approach that leverages cutting-edge technology. Unlike standard treatments that often follow a one-size-fits-all protocol, this method uses real-time high-throughput drug screening, whole exome sequencing (WES), and RNA sequencing to tailor a treatment plan specifically for each patient. This individualized strategy can potentially identify the most effective combination of up to four FDA-approved drugs much faster, within just 21 business days, offering a customized and timely solution for patients.

What evidence suggests that this trial's treatments could be effective for medulloblastoma?

Research has shown that personalized treatment plans for medulloblastoma can be effective. In one study with 69 patients, children had a survival rate of 77.7%, while adults had a rate of 61%. These results suggest that treatments tailored to each person can improve outcomes. In this trial, participants will receive an individualized treatment recommendation, created by a team of experts known as a tumor board, based on the specific details of each person's tumor. This method aims to provide the most effective and least harmful treatments available. ^{3 4 6 7 8}

Published Research Related to This Trial

Maximal safe surgery is the first step in treating medulloblastoma, followed by thorough staging and risk stratification based on histopathological and neuroradiological assessments, which should be conducted by experienced specialists.

For young children with specific types of medulloblastoma, such as desmoplastic/nodular, radiotherapy should be avoided, while older patients may require intensified treatment strategies, including high-dose chemotherapy and radiotherapy, to improve outcomes.

Medulloblastomas (MBs) can be classified into at least four core subgroups (WNT, SHH, Group 3, and Group 4) based on genetic and molecular characteristics, which can influence treatment outcomes and prognosis.

New approaches to treatment are being explored, including low-dose craniospinal irradiation and targeted molecular therapies, which aim to improve patient outcomes while minimizing side effects by tailoring interventions to the specific molecular profile of each tumor.

Medulloblastomas are the most common malignant brain tumors in children, and their treatment requires a multidisciplinary approach due to their rarity and complexity.

Recent advancements in molecular understanding have led to risk-adapted treatment strategies that improve outcomes for high-risk patients while reducing long-term side effects.

The EORTC 1634-BTG/NOA-23 trial aims to improve treatment for post-pubertal medulloblastoma patients by comparing standard-dose versus reduced-dose craniospinal radiotherapy and adding the SMO inhibitor sonidegib to standard therapy, potentially reducing toxicity and enhancing efficacy.

This study will provide valuable long-term data on treatment side effects and quality of life, which is crucial for developing better treatment strategies for this rare brain cancer in adults.

In a Phase II study involving 53 children with high-risk medulloblastoma, oral etoposide was found to be tolerable and effective when administered during radiotherapy, leading to a high response rate with 40.4% achieving complete response and 51.1% partial response.

The study reported promising survival rates, with 2-year progression-free survival (PFS) at 76.6% and overall survival (OS) at 80.9%, indicating that this treatment regimen could improve outcomes for children with this aggressive form of cancer.

In a study of 47 adult medulloblastoma patients treated under the Dutch protocol, combined chemo-radiotherapy showed potential for improved survival, with 5-year progression-free survival rates of 69% for standard-risk patients and 90% for high-risk patients, although these results were not statistically significant.

The treatment regimen was associated with considerable toxicity, leading to treatment reductions and delays, particularly due to hematological and neurotoxicity, highlighting the need for careful management of side effects in this patient population.

In a study of 338 non-metastatic medulloblastoma patients, the WNT subgroup (MBWNT) was confirmed to have a favorable prognosis, but non-MBWNT tumors showed better outcomes than previously reported in broader trials, indicating the need for tailored risk assessments.

Chromosome 17 defects were found to predict poor prognosis in certain genetic backgrounds, and specific biomarkers, including patterns of chromosome 17 imbalance and MBWNT status, are essential for improving risk stratification in standard-risk medulloblastoma patients.

Long-term survival rates for adults with medulloblastoma are approximately 50-60% at 5 years and 40-50% at 10 years, indicating that effective treatment strategies can lead to significant survival outcomes.

The cornerstone of treatment includes radical surgery followed by specific adjuvant radiotherapy and chemotherapy regimens, with careful timing and dosage to avoid adverse effects, particularly concerning the patients' hematopoietic reserves.

Medulloblastoma, the most common malignant brain tumor in children, presents significant challenges in long-term survival and quality of life, prompting the integration of molecular subgrouping into treatment strategies to better risk stratify patients.

Current clinical trials are exploring innovative therapies, including precision medicine, epigenetic modifications, and immune therapies, to improve outcomes for patients with relapsed medulloblastoma, reflecting a commitment to advancing treatment through collaborative research efforts.

A modified chemotherapy regimen for young children with medulloblastoma, which reduced the number of intrathecal methotrexate doses and eliminated the need for Ommaya reservoir implantation, showed promising results with four out of five patients remaining in remission for 3 to 10 years post-treatment.

The approach demonstrated safety, as no learning difficulties were observed in the children who remained in remission, suggesting that this modified treatment could be a viable option for reducing neurocognitive deficits associated with traditional radiotherapy.
