What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new method for treating recurrent glioblastoma, a type of brain cancer. It combines a device called SonoCloud-9 (SC9) with chemotherapy drugs like carboplatin. SC9 uses ultrasound to temporarily open a barrier, allowing these drugs to reach the brain. The trial will compare this method with standard chemotherapy treatments to determine its effectiveness. Ideal candidates for this trial are those whose glioblastoma has returned after initial treatment and who are prepared for additional surgery to remove part of the tumor. As a Phase 3 trial, this study is the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but it mentions that patients on certain enzyme-inducing antiepileptic drugs must switch to another regimen. Additionally, those on anti-platelet or anticoagulation therapy may need to temporarily interrupt their medication after discussion with the sponsor.

What prior data suggests that the SonoCloud-9 device is safe for use in combination with carboplatin?

Research has shown that using the SonoCloud-9 device with the chemotherapy drug carboplatin is generally safe. One study found that the SonoCloud-9 can temporarily open the blood-brain barrier, allowing more carboplatin to reach brain tumors. Participants tolerated this process well. Another study demonstrated that this method effectively opened the barrier around a large tumor area without causing major side effects.

Carboplatin is already an approved treatment for other types of cancer, indicating its general safety. When combined with the SonoCloud-9, no significant additional risks were reported. These findings suggest that the treatment is well-tolerated, but discussing participation in a trial with a doctor is essential.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial's treatments?

Researchers are excited about the ultrasound-assisted chemotherapy for glioblastoma because it offers a novel approach to treatment. Unlike standard care options like temozolomide (TMZ) or lomustine (CCNU), which are administered orally, this treatment combines the chemotherapy drug carboplatin with the SonoCloud-9 ultrasound device. This device is implanted in the skull and helps enhance the delivery of the drug directly to the brain, potentially increasing its effectiveness. This innovative method could improve drug penetration into the tumor, making it a game-changer in treating this aggressive form of brain cancer.

What evidence suggests that the SonoCloud-9 device is effective for opening the blood-brain barrier in glioblastoma treatment?

In this trial, participants in the experimental arm will receive the SonoCloud-9 ultrasound device combined with the drug carboplatin. Research has shown that this combination helps more of the drug reach brain tumor tissue. Glioblastoma, a type of brain cancer, is difficult to treat because the blood-brain barrier (BBB) usually prevents drugs from entering the brain. The SonoCloud-9 device uses ultrasound to temporarily open the BBB, allowing more carboplatin to reach the tumor. Previous studies suggest that increased carboplatin in the brain may enhance treatment effectiveness. This combination offers a promising approach for treating recurrent glioblastoma by potentially boosting the effects of chemotherapy. Meanwhile, the control arm will receive standard care with either temozolomide (TMZ) or lomustine (CCNU).² ³ ⁴ ⁶ ⁷

Are You a Good Fit for This Trial?

Adults over 18 with confirmed glioblastoma who've had prior surgery, radiotherapy, and chemotherapy can join. They must have a tumor that's grown after treatment but is less than 5 cm wide. Participants need good organ function, no severe allergies to trial drugs or device components, and not be on certain medications like anti-platelet drugs.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive either SonoCloud-9 with Carboplatin or standard chemotherapy (TMZ or CCNU). SonoCloud-9 with Carboplatin is administered every 3 weeks for up to 7 cycles, while TMZ is given every 4 weeks for up to 6 cycles, and CCNU every 6 weeks for up to 4 cycles.

Up to 24 weeks

Follow-up

Participants are monitored for safety and effectiveness after treatment, with survival status collected during the treatment period and every 3 months thereafter.

Up to 24 months

Long-term follow-up

Participants continue to be monitored for overall survival and progression-free survival every 3 months as part of standard care follow-up.

What Are the Treatments Tested in This Trial?

Interventions

Carboplatin
SonoCloud-9 (SC9)

Trial Overview The trial tests if using SonoCloud-9 (SC9), an ultrasound device designed to temporarily open the blood-brain barrier (BBB), increases the effectiveness of Carboplatin in treating recurrent glioblastoma compared to standard chemotherapies Lomustine or Temozolomide alone.

How Is the Trial Designed?

2Treatment groups

Experimental Treatment

Active Control

Group I: Experimental Arm: SonoCloud-9 Ultrasound + CarboplatinExperimental Treatment2 Interventions

The SonoCloud-9 (SC9) device will be implanted in the skull bone window upon completion of tumor resection and routine craniotomy. Carboplatin (CBDCA) will be administered intravenously prior to sonication. The CBDCA/SC9 treatment will be repeated every 3 weeks (depending on patient's tolerability) until disease progression or as clinically indicated. Administration of up to 7 cycles is planned.

Group II: Control Arm: SoC single agent chemotherapy TMZ or CCNUActive Control2 Interventions

Standard of Care (SoC) treatment with either temozolomide (TMZ) or lomustine (CCNU). Standard TMZ chemotherapy as a single oral dose every 4 weeks for up to 6 cycles. Standard CCNU chemotherapy as a single oral dose every 6 weeks for up to 4 cycles.

Published Research Related to This Trial

The interim results from a phase 1/2a clinical trial involving patients with recurrent glioblastoma show that using pulsed ultrasound to disrupt the blood-brain barrier (BBB) is safe and well tolerated, with no detectable adverse effects observed during MRI or clinical examinations.

This method, which combines pulsed ultrasound with systemic microbubble injection, effectively increases drug delivery to the brain and has the potential to enhance the efficacy of chemotherapy treatments like carboplatin.

Clinical trial of blood-brain barrier disruption by pulsed ultrasound.Carpentier, A., Canney, M., Vignot, A., et al.[2017]

A Phase I clinical trial involving 10 patients with recurrent high-grade gliomas demonstrated that intracerebral convection-enhanced delivery (CED) of carboplatin is feasible and safe at doses up to 4μg over 72 hours, with only one possible adverse event reported.

The median progression-free survival (PFS) and overall survival (OS) after treatment were 2.1 months and 9.6 months, respectively, indicating that while the treatment is safe, further studies are needed to assess its efficacy in improving patient outcomes.

Phase I trial of intracerebral convection-enhanced delivery of carboplatin for treatment of recurrent high-grade gliomas.Wang, JL., Barth, RF., Cavaliere, R., et al.[2021]

The study demonstrates the successful use of a novel implantable convection-enhanced delivery (CED) system for carboplatin in a patient with recurrent glioblastoma, showing precise catheter placement and well-tolerated drug infusions.

Follow-up MRI results indicated a significant reduction in tumor volume from 42.6 ml to 24.6 ml after treatment, suggesting that CED of carboplatin may improve clinical outcomes for glioblastoma patients by effectively bypassing the blood-brain barrier.
