Brief Summary

This Phase II trial tests if sonodynamic therapy (SDT)-a non-invasive treatment using ultrasound to activate a cancer-killing drug-improves outcomes for newly diagnosed glioblastoma patients.

Who? 230 adults (<75 years) with confirmed glioblastoma, adequate organ function, no major health issues.

Groups:

Test Group: SDT + standard therapy (radiation, chemo, bevacizumab). Control Group: Standard therapy alone.

Procedure:

SDT uses the drug Hiporfin® followed by focused ultrasound sessions. Patients avoid sunlight for 1 month.

Study Duration:

Treatment: ~6-8 weeks. Follow-up: 24 months (monthly MRIs).

Key Goal:

Compare progression-free survival (time until tumor worsens) between groups. Secondary goals: overall survival, safety.

Detailed Description

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 This trial builds on Phase I results (unpublished) showing SDT induced tumor shrinkage in recurrent GBM with minimal toxicity.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.
