Glioblastoma Clinical Trial
Official title:
Ultrasound Imaging in Brain Tumour Surgery With the Use of SonoClear Acoustic Coupling Fluid (ACF) Mimicking Brain Tissue
The objective of this clinical investigation is to assess the safety and performance of the SonoClear Acoustic Coupling Fluid (ACF). The performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single-arm study where the performance of SonoClear ACF relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of HGG and LGG at up to 10 sites will be included. Additionally, safety data are collected at 30 days and 6 months post-procedure.
Ultrasound images will be obtained at different timepoints during the operation. First timepoint being after craniotomy (no fluids involved). Second timepoint being when some tumour is left in the bottom of the deeper part of the resection cavity (approximately 80% of tumour removed), and third timepoint being when the surgeon deems resection of the tumour to be completed. At the second and third timepoint ultrasound acquisition will be performed twice at each timepoint. Once with routinely used saline / Ringer's solution and once with SonoClear ACF. There are two performance related primary endpoints, based on core lab assessments: 1. To show that ultrasound images obtained with SonoClear ACF are less influenced by image artefacts compared to images obtained with standard of care saline or Ringer´s solution, by measuring the contrast-to-noise ratio (CNR). The CNR is a measure of the relative noise in the image. To achieve this endpoint, the use of SonoClear ACF must lead to superior image quality in comparison with Saline/Ringer´s solution. Superior image quality is defined as the CNR being statistically different between the images obtained with saline/Ringer and SonoClear ACF respectively, i.e., significantly less noise in the images obtained with SonoClear ACF. 2. To show that ultrasound images obtained with SonoClear ACF are of better quality compared to images obtained with standard of care Saline/Ringer's solution, by using a qualitative assessment, called the Surgeons Image Rating (SIR) scale. A Panel of Experts will assess the quality of the obtained images by answering 3 questions for each image. The SIR a 1-10 numeric rating scale, is used to measure the quality of the image according to three questions to be answered at the three different timepoints during the operation. This SIR is designed to explore whether SonoClear ACF, having shown to provide better quantitative image quality in the CNR analysis, allows surgeons to detect this improved image quality. Eventually this improved image quality should result in better decision-making during surgery about margins of excision and residual tumour resection. Primary Safety Endpoint The primary safety hypothesis is to prove the primary safety event rate is less than 10%. The primary safety event is defined as any core lab determined major MRI finding when post-operative MRI is compared to pre-operative MRI that was found by the DMC to be serious and probably or definitely related to the study device OR any DMC determined serious adverse event that is probably or definitely related to the study device that occurs within 30 days of the procedure. Success is demonstrated by observing 0 of these events out of 37 subjects exposed to SonoClear ACF. This is equivalent to a two-sided p-value less 0.05 for the alternative hypothesis that the primary safety event rate in subjects undergoing tumor resection using ACF is less than 10%. ;
