Whole Brain Radiotherapy for Brain Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two methods of whole brain radiotherapy (HA-WBRT and MA-WBRT) for treating cancer that has spread to the brain. One method avoids the hippocampus, crucial for memory, while the other avoids additional brain structures that may aid thinking and memory. Researchers aim to determine which method better protects cognitive function. Individuals with at least 10 brain tumors who can receive whole brain radiotherapy might be suitable for this study. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to significant findings.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that treatments like Memory Avoidance Whole Brain Radiation Therapy (MA-WBRT) and Hippocampal Avoidance Whole Brain Radiation Therapy (HA-WBRT) protect brain health while treating cancer that has spread to the brain.
Studies have found that HA-WBRT helps safeguard memory and overall brain function. Specifically, patients reported fewer issues with memory and thinking skills. One study showed that HA-WBRT reduced the risk of memory and thinking problems compared to other methods.
While fewer specific studies exist for MA-WBRT, similar treatments have been noted to help maintain brain functions like memory and thinking.
Both treatments aim to avoid harming parts of the brain important for memory and thinking while still targeting cancer cells. So far, they appear well-tolerated, focusing on reducing side effects related to brain function.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the new approaches to whole brain radiotherapy for brain cancer, specifically MA-WBRT and HA-WBRT, because they aim to minimize cognitive side effects. Unlike traditional whole brain radiation therapy, which often affects memory and cognitive function, MA-WBRT focuses on avoiding damage to memory-critical areas of the brain. Similarly, HA-WBRT targets the hippocampus, a region vital for memory, to reduce the risk of cognitive decline. These innovative techniques could mean better quality of life for patients by preserving memory and mental function while effectively treating cancer.
What evidence suggests that this trial's treatments could be effective for brain cancer?
This trial will compare two treatments: Memory Avoidance Whole Brain Radiation Therapy (MA-WBRT) and Hippocampal Avoidance Whole Brain Radiation Therapy (HA-WBRT). Research has shown that whole brain radiotherapy (WBRT) can treat cancer that has spread to the brain, but it often impacts memory and thinking skills. Participants receiving MA-WBRT, one of the treatments in this trial, demonstrated a lower rate of cognitive decline—about 17% at three months—compared to traditional WBRT, and generally have better memory scores over time. Meanwhile, HA-WBRT, another treatment option in this trial, aims to protect the hippocampus, a part of the brain crucial for memory. Early findings suggest both treatments strive to preserve thinking skills while treating brain cancer. Overall, these treatments aim to reduce memory problems while targeting cancer cells.14678

Are You a Good Fit for This Trial?
This trial is for individuals with cancer that has spread to the brain (brain metastases). Participants should be suitable for radiotherapy and willing to take medication aimed at preserving cognitive function. Specific eligibility criteria are not provided, but typically include factors like overall health status, age range, and absence of certain medical conditions.Inclusion Criteria

Trial Overview
The Athena 2 Trial is comparing two types of whole brain radiotherapy: one avoids the hippocampus (HA-WBRT), while the other avoids additional areas linked to memory (MA-WBRT). Both methods are combined with a drug called Memantine. The goal is to see which better preserves cognitive functions in patients.
