Holmium-166 Scout (QuiremScout®) has shown superior predictive value

​when compared to technetium-99m-macroaggregated albumin during SIRT work-up

29/10/2019 - LEUVEN, BELGIUM

Terumo Europe N.V. is proud to share our latest key publication regarding holmium-166 (QuiremSpheres®) Selective Internal Radiation Therapy (SIRT). On 9th August 2019, UMC Utrecht published its results from a recent study on the comparison of QuiremScout® to technetium-99m-macroaggregated albumin (99mTc-MAA) as a SIRT work-up which is used to select patients with liver cancer who will benefit from SIRT treatment.

The aim of this study was to analyze whether the intrahepatic distribution of QuiremScout® has a better agreement with the QuiremSpheres® distribution when compared with 99mTc-MAA. It has been indicated in several scientific papers, the widely used Tech-99m-MAA has limited predictive value.
This study included 53 patients which had been included in either phase 1 and phase 2 Holmium Embolization Particles for Arterial Radiotherapy (HEPAR) studies and showed QuiremScout® to have a superior predictive value for intrahepatic distribution in comparison to 99mTc-MAA.
“Previous studies already demonstrated that QuiremScout® is safe1 in this population and moreover a better predictor for lung shunting than to 99mTc-MAA. As a result, QuiremScout® allows for more accurate SIRT patient selection. Now, our study shows the potential of QuiremScout® to also improve the efficacy of SIRT, by allowing a more accurate and truly personalized pre-treatment activity planning.” says Maarten Smits MD PhD, first author of the article2.
“This is an important next step towards unlocking the full potential of QuiremScout®.” said Rijk de Jong, Medical Director of Quirem Medical. “Smits et al. publication further strengthens the evidence base of QuiremScout®, demonstrating superiority over 99mTc-MAA in the evaluation of the subsequent treatment. We believe this will translate into enhanced efficacy and safety for the benefit of patients undergoing SIRT procedures”
“This is a very exciting milestone for QuiremScout® and the next step in building the future for SIRT.” added Peter Coenen, President of Interventional systems Terumo EMEA. “This publication further validates the advantages of QuiremScout® over 99mTc-MAA during the SIRT work up, which we at Terumo believe is a vital step in advancing patient selection and optimizing dosimetry for better patient outcomes”.
Results from this trial are published in the European Journal of Nuclear Medicine Molecular Imaging 2019.
QuiremScout® is the first SIRT work-up product that utilizes the same technology as the therapeutic microspheres, which aims to optimize patient selection and advance treatment planning when compared to using 99mTc-MAA.
