What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new method for treating glioblastoma, a type of brain cancer, by using ultrasound to help chemotherapy drugs reach the tumor more effectively. The treatment temporarily opens the blood-brain barrier, a protective layer that usually keeps substances out of the brain, allowing the drugs carboplatin and paclitaxel to enter and work better. Patients with a confirmed diagnosis of glioblastoma who have experienced tumor progression after one or two prior treatments might be suitable for this trial. The trial aims to find a safe and effective dose, increase drug concentration in the tumor, and determine if this approach can reduce the tumor and improve survival. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering patients the opportunity to be among the first to receive this innovative therapy.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on enzyme-inducing antiepileptics or need to continue antiplatelet therapy, you may not be eligible to participate.

What prior data suggests that this ultrasound-assisted chemotherapy technique is safe for glioblastoma patients?

In a previous study, patients received a treatment using ultrasound to open the blood-brain barrier (BBB), successfully targeting 90% of the area. This indicates that the treatment effectively reached the brain. The procedure was well-tolerated and did not cause any major side effects.

Research shows that paclitaxel can accumulate in the brain without causing noticeable harm, which is promising for treating brain tumors like glioblastoma. It appears safe when used in controlled doses.

Carboplatin has been used in other studies for brain tumors, and results show it can help some patients live longer. While carboplatin can have side effects, they are generally known and manageable.

Overall, treatments in past studies have been safe and tolerable, with no severe reactions reported. This suggests a good level of safety for those considering joining this trial. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this treatment for glioblastoma because it uses a unique approach to improve chemotherapy effectiveness. Unlike the standard treatments, which often struggle to penetrate the blood-brain barrier, this technique uses ultrasound waves and microbubbles to temporarily open the barrier. This allows for a more direct delivery of chemotherapy drugs like carboplatin and albumin-bound paclitaxel to the tumor site. By enhancing drug delivery, this method has the potential to increase the effectiveness of the treatment while minimizing damage to healthy brain tissue.

What evidence suggests that this ultrasound-assisted chemotherapy is effective for glioblastoma?

Research has shown that ultrasound can enhance the effectiveness of chemotherapy for glioblastoma, a type of brain cancer. This trial will investigate using ultrasound to open the blood-brain barrier, a protective layer around the brain, allowing drugs like paclitaxel and carboplatin to reach the tumor more effectively. Early tests demonstrated that combining these two drugs was more effective than using paclitaxel alone. Specifically, ultrasound increased the amount of carboplatin in the brain tissue by over five times in the targeted area. These findings suggest that ultrasound with chemotherapy could significantly improve treatment effectiveness against glioblastoma. Participants in this trial will receive albumin-bound paclitaxel and carboplatin, with ultrasound-assisted delivery to enhance drug penetration. ^{5 6 7 8 9}

Trial Overview The trial tests if using ultrasound to open the blood-brain barrier before giving chemotherapy (albumin-bound paclitaxel followed by carboplatin) can safely improve treatment outcomes in recurrent glioblastoma patients. The study will determine safe dosages and measure how well this method delivers chemo into the tumor.

How Is the Trial Designed?

Published Research Related to This Trial

Using ultrasound to open the blood-brain barrier significantly increased the concentration of carboplatin in brain tissue by 5.2 times in the targeted area, suggesting a more effective delivery method for treating glioblastoma.

This method of enhancing drug delivery is currently being evaluated in a phase 1 clinical trial, indicating its potential as a promising approach for improving treatment outcomes in patients with aggressive brain tumors.

The combination of paclitaxel and carboplatin demonstrated a 53.3% objective response rate in 15 patients with stage III B and IV non-small cell lung cancer (NSCLC), indicating moderate efficacy in treating advanced disease.

While the regimen was associated with significant myelosuppression, including grade 3-4 granulocytopenia in 18% of treatment courses, most toxicities were manageable and well tolerated, suggesting a favorable safety profile for this chemotherapy combination.

Low-intensity pulsed ultrasound (LIPU) significantly enhances the delivery of paclitaxel across the blood-brain barrier, increasing drug concentration in the brain by 3- to 5-fold, which improves treatment efficacy for glioma.

Among the two formulations tested, albumin-bound paclitaxel (ABX) not only extended survival in glioma models but also showed better tolerability compared to paclitaxel dissolved in cremophor (CrEL-PTX), making ABX the preferred option for future clinical studies.

In a clinical trial involving 21 patients with recurrent glioblastoma, the use of the SonoCloud-1 device to transiently disrupt the blood-brain barrier (BBB) before chemotherapy with carboplatin was well tolerated, with only manageable and transient side effects observed.

Patients who experienced clear BBB disruption had significantly better outcomes, with a median progression-free survival of 4.11 months and overall survival of 12.94 months, compared to those with poor disruption, highlighting the potential of LIPU to enhance drug delivery in brain tumors.

The biomimetic nanosonosensitizer systems (MDNPs) effectively target glioblastoma (GBM) by using human GBM cell membranes to enhance drug delivery and can cross the blood-brain barrier with the help of ultrasound, improving treatment accessibility.

MDNPs not only induce cancer cell death through the generation of reactive oxygen species (ROS) but also reduce drug resistance, leading to significantly improved survival rates in mice treated with low-dose doxorubicin and ultrasound, demonstrating both efficacy and safety in repeated treatments.

The study demonstrated that low-intensity pulsed ultrasound combined with intravenous microbubbles (LIPU-MB) can safely and effectively open the blood-brain barrier, allowing for increased delivery of albumin-bound paclitaxel and carboplatin to the brain in patients with recurrent glioblastoma.

In a trial involving 17 patients, LIPU-MB resulted in a significant increase in drug concentrations in the brain (3.7 times for paclitaxel and 5.9 times for carboplatin), with manageable side effects and no treatment-related deaths, supporting its potential for further clinical use.

In two ongoing dose-finding studies involving 33 patients with advanced non-small cell lung cancer (NSCLC) and 11 with advanced ovarian cancer, the combination of paclitaxel and carboplatin is being tested to determine optimal dosing, with paclitaxel administered as a 3-hour infusion.

The most common side effect observed was neutropenia, but it did not lead to any infections, indicating a manageable safety profile; other side effects included hair loss and mild nausea, with no significant differences in toxicity based on the order of drug administration.

In a phase II trial involving 31 patients with nonoperable stage III and IV non-small cell lung cancer (NSCLC), the combination of paclitaxel and carboplatin showed promising efficacy, with 33% of evaluable patients achieving a partial response and 48% having stable disease.

The treatment was generally well tolerated, with manageable side effects; however, 10.7% of patients experienced grade 2/3 neutropenia, and there was one reported death due to a severe allergic reaction, indicating the need for careful monitoring.
