Study Summary

This trial will assess whether FUS can safely open the blood brain barrier, allowing a greater concentration of the drug to reach into the brain tumor, potentially improving response and reducing side effects.

Who is the study for?
Children and young adults aged 4-21 with a specific brain tumor called Diffuse Midline Glioma, involving the pons or thalami, can join this trial. They must have a certain level of physical ability (Lansky or Karnofsky score ≥60), proper organ function, and be off other cancer treatments for a set time. Those who've had etoposide before, are pregnant/breastfeeding, have uncontrolled seizures or infections, heart issues, bleeding disorders, metal implants/electrical devices in body cannot participate.Check my eligibility
What is being tested?
The study is testing if focused ultrasound (FUS) can safely open the blood-brain barrier to let more of the drug etoposide reach brain tumors in children with progressive diffuse midline gliomas. FUS uses microbubbles and sound waves guided by neuro-navigation to target areas around the tumor while giving oral etoposide.See study design
What are the potential side effects?
Potential side effects include those related to opening up the blood-brain barrier like temporary neurological changes or discomfort from sound wave application. Etoposide may cause low blood counts leading to infection risk increase; nausea; hair loss; mouth sores; diarrhea.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is the age range for this research restricted to adults under 45?

"This clinical trial is enrolling participants between the ages of four and twenty-one."

Answered by AI

Is there an opportunity for me to join this investigation?

"Potential participants in this study must have diffuse intrinsic pontine glioma and be aged between 4 and 21. The trial is accepting around 10 people on a first come, first served basis."

Answered by AI

Does this experiment need more participants at present?

"Data published on clinicaltrials.gov reveals that this research endeavour is actively seeking participants, which was first announced March 1st 2023 and last updated February 28th 2023."

Answered by AI

How many participants have been recruited to partake in this experiment?

"Indeed, the information provided on clinicaltrials.gov suggests that this medical research is currently in search of participants. This experiment was initially shared online on March 1st 2023 and underwent a revision at the end of February 2023. The team behind this trial plans to enrol 10 patients from one site."

Answered by AI

Has the FDA authorized using oral etoposide for Focused ultrasound treatment?

"Our team's assessment of the safety profile of Focused ultrasound using oral etoposide is a 1, as it has only been tested in preliminary clinical trials. As such, there is limited data to support its efficacy and safety."

Answered by AI

What goals are researchers looking to achieve with this experiment?

"The primary purpose of this trial is to establish the number of patients who experience successful permeability of their blood-brain barrier. This will be evaluated approximately 90 days after completion of focused ultrasound treatment. Further, a secondary objective includes 3-month overall survival which refers to the period between initial treatment and death from any cause. To measure this outcome, participants will have follow up visits at intervals ranging from every three to six months or until passing away for whatever reason. An additional aim focuses on imaging changes in regards to the BBB/Tumor and identifying severe or serious adverse events with CTCAE version 5.0 noting that throm"
