What is the mechanism of action of this treatment?

The most common treatments for brain tumors include radiation therapy, chemotherapy, antiangiogenic therapy, and investigational therapies. Radiation therapy works by damaging the DNA of cancer cells, thereby inhibiting their ability to replicate. Chemotherapy, such as temozolomide, interferes with the DNA replication process, leading to cell death. Antiangiogenic therapy, like bevacizumab, targets the blood vessels that supply the tumor, effectively starving it of nutrients. Investigational therapies, such as ONC201 and CAR T-cell therapy, focus on targeting specific molecular pathways and immune responses. Understanding these mechanisms is crucial for brain tumor patients as it helps in tailoring personalized treatment plans and improving outcomes. Advanced brain imaging techniques like MRI and PET play a significant role in monitoring these treatments and predicting tumor mutations, thereby aiding in the timely adjustment of therapeutic strategies.

What side effects are associated with this type of intervention?

Common treatments for brain tumors, including radiation therapy and chemotherapy with temozolomide, often result in side effects such as fatigue, nausea, vomiting, hair loss, and increased risk of infections due to bone marrow suppression. Radiation therapy can also cause localized side effects like skin irritation and neurocognitive deficits. Investigational therapies like ONC201 and DNX-2401 may have unique side effects, but data is still emerging. ONC201 has shown some promise with manageable side effects, while DNX-2401, an oncolytic virus, may cause inflammation and flu-like symptoms. Patients should discuss potential side effects with their healthcare provider to make informed decisions.

What prior FDA approvals exist?

FDA approvals for the treatment of brain tumors, particularly gliomas and glioblastomas, have included drugs like temozolomide, which is often used in combination with radiotherapy. Bevacizumab, an antiangiogenic agent, has also been approved for recurrent glioblastoma. These treatments are part of ongoing efforts to improve outcomes through advanced imaging techniques such as MRI and PET, which are being studied to monitor and predict tumor mutations more effectively.

What other types of research exist?

Promising novel alternatives to advanced brain imaging for brain tumor patients include: 1) Pharmacologic inhibition of histone demethylation, which targets specific genetic mutations in tumors. 2) Chimeric Antigen Receptor (CAR) T-cell therapy targeting GD2, a marker on certain glioma cells. 3) The investigational oral compound ONC201, which has shown efficacy in H3 K27M-mutant gliomas. 4) Local therapies such as DNX-2401, an oncolytic adenovirus administered directly to the tumor site. These alternatives are under active investigation and may offer new avenues for treatment and monitoring in 2024.

ReGIT Trial Summary

This trial is studying how brain tumors might change over time and whether newer brain imaging tools like MRI and PET can predict these changes.

Who is the study for?

This trial is for adults aged 18-89 with a newly diagnosed Grade II-IV glioma brain tumor, who can lay still for imaging tests and are planning surgery to remove the tumor. They must be able to read/write in English and not have any conditions that prevent MRI scans.Check my eligibility

What is being tested?

The study examines how brain tumors change over time using advanced imaging techniques like MRI/PET scans combined with biopsies. It aims to see if these tools can predict genetic mutations in the tumors.See study design

What are the potential side effects?

Potential side effects may include discomfort from lying still during long imaging sessions, reactions to contrast agents used in MRIs (like allergic reactions or kidney problems), and risks associated with biopsy procedures.
