Detailed Description
This single-center, randomized, open-label Phase II trial evaluates the synergistic efficacy and safety of sonodynamic therapy (SDT) combined with standard chemoradiotherapy in newly diagnosed glioblastoma (GBM). While the Brief Summary outlines the trial's scope, this section elaborates on mechanistic, methodological, and analytical nuances not captured elsewhere.
Scientific Rationale SDT leverages low-intensity, low-frequency focused ultrasound (LILFU) (800 kHz-1 MHz, 1-1.25 W/cm²) to activate the sonosensitizer Hiporfin® (5 mg/kg), generating cytotoxic reactive oxygen species (ROS) selectively within tumor cells. Preclinical data demonstrate SDT disrupts mitochondrial function, enhances DNA damage from temozolomide, and promotes immunogenic cell death. This trial builds on Phase I results (unpublished) showing SDT induced tumor shrinkage in recurrent GBM with minimal toxicity.
Intervention Specifics
SDT Protocol:
Timing: Initiated 40 hours post-Hiporfin® administration to optimize tumor drug accumulation.
Ultrasound Parameters:
Frequency: 800 kHz-1 MHz (adjustable for tumor depth). Intensity: 1-1.25 W/cm² (below cavitation threshold to minimize tissue damage). Duration: 15 minutes/session, repeated at 24h, 48h, and 72h. Localized Delivery: Adults receive Hiporfin® via intra-arterial infusion (maximizing tumor uptake); children receive intravenous dosing (safety precaution).
Standard Therapy:
Radiation: 50-54 Gy in 1.8-2 Gy fractions (25 sessions). Temozolomide: 75 mg/m²/day concurrent with radiation; escalated to 150-200 mg/m²/day post-radiation.
Bevacizumab: 7.5-10 mg/kg every 3 weeks (angiogenesis inhibition). Methodological Rigor Stratified Randomization: Patients are stratified by tumor location (supratentorial vs. deep midline), size (<4 cm vs. ≥4 cm), and residual post-surgical volume to balance prognostic factors.
Imaging Protocol: MRI scans (T1-weighted with contrast, FLAIR) are standardized across timepoints (baseline, monthly post-treatment) and analyzed centrally using 3D volumetric segmentation to reduce inter-rater variability.
Safety Monitoring:
Phototoxicity Mitigation: Strict 30-day light avoidance protocol with ambient light levels monitored.
Real-Time AE Tracking: Adverse events (e.g., skin reactions, CNS edema) are graded per WHO criteria and managed via a pre-specified escalation algorithm.
Statistical Analysis Primary Endpoint: Progression-free survival (PFS) analyzed via stratified log-rank test (α=0.05, two-sided), adjusting for stratification factors.
Secondary Endpoints:
Overall survival (OS) analyzed using Weibull parametric survival models. Tumor control rate (CR+PR+SD) assessed via RECIST 1.1 with RANO criteria for neurologic tumors.
Exploratory Analysis: Biomarker correlation (EGFR expression, ROS levels) with SDT response using multiplex IHC and RNA sequencing.
Innovation \& Impact
This trial is the first to integrate SDT with standard GBM therapy in a randomized design. If successful, SDT could address critical unmet needs:
Non-invasive targeting of deep/inoperable tumors. ROS-mediated chemo/radio-sensitization to overcome treatment resistance. Reduced neurotoxicity vs. traditional therapies.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sonodynamic Therapy (SDT) and Standard Treatment in people with Glioblastoma (GBM), run by Yingjuan Zheng at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: enrolling by invitation, as of the sponsor's last update on 19 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression - free survival (PFS) (time frame: It is evaluated for up to 5 years from the date of randomization to the date of first documented progression or death from any cause, whichever comes first). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2025; AzTrials last refreshed its copy on 6 Nov 2026.
