Acoustic Cluster Therapy (ACT) - pre-clinical proof of principle for local drug delivery and enhanced uptake.
van Wamel, Annemieke; Healey, Andrew; Sontum, Per C.; Kvåle, Svein; Bush, Nigel; Bamber, Jeffrey; Davies, Ruth Catharina de Lange (Journal article; Peer reviewed, 2016)Proof of principle for local drug delivery with Acoustic Cluster Therapy (ACT) was demonstrated in a human prostate adenocarcinoma growing in athymic mice, using near infrared (NIR) dyes as model molecules. A dispersion ... -
Acoustic Cluster Therapy (ACT) enhances the therapeutic efficacy of paclitaxel and Abraxane® for treatment of human prostate adenocarcinoma in mice
van Wamel, Annemieke; Sontum, Per C.; Healey, Andrew; Kvåle, Svein; Bush, Nigel; Bamber, Jeffrey; Davies, Ruth Catharina de Lange (Journal article; Peer reviewed, 2016)Acoustic cluster therapy (ACT) is a novel approach for ultrasound mediated, targeted drug delivery. In the current study, we have investigated ACT in combination with paclitaxel and Abraxane® for treatment of a subcutaneous ... -
Effect of Acoustic Radiation Force on the Distribution of Nanoparticles in Solid Tumors.
Afadzi, Mercy; Myhre, Ola Finneng; Yemane, Petros Tesfamichael; Bjørkøy, Astrid; Torp, Sverre Helge; van Wamel, Annemieke; Lelu, Sylvie; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Peer reviewed; Journal article, 2020)Acoustic radiation force (ARF) might improve the distribution of nanoparticles (NPs) in tumors. To study this, tumors growing subcutaneously in mice were exposed to focused ultrasound (FUS) either 15 min or 4 h after the ... -
Efficient Enhancement of Blood–Brain Barrier Permeability Using Acoustic Cluster Therapy (ACT)
Åslund, Karl Olof Andreas; Snipstad, Sofie; Healey, Andrew J.; Kvåle, Svein; Torp, Sverre Helge; Sontum, Per C.; Davies, Ruth Catharina de Lange; van Wamel, Annemieke (Journal article; Peer reviewed, 2017)The blood-brain barrier (BBB) is a major obstacle in drug delivery for diseases of the brain, and today there is no standardized route to surpass it. One technique to locally and transiently disrupt the BBB, is focused ... -
Method development and automated analysis of ultrasound images of phase-shift bubbles.
Sulheim, Snorre (Master thesis, 2015)Ultrasound mediated drug delivery is an important tool in the fight against cancer. A new concept called Acoustic Cluster Therapy (ACT ) is under development, and two pilot imaging studies have been performed on prostate cancer ... -
Multi-modal characterization of vasculature and nanoparticle accumulation in five tumor xenograft models
Sulheim, Einar; Kim, Jana; van Wamel, Annemieke; Kim, Eugene; Snipstad, Sofie; Vidic, Igor; Grimstad, Ingeborg; Widerøe, Marius; Torp, Sverre Helge; Lundgren, Steinar; Waxman, David J.; Davies, Catharina de Lange (Journal article; Peer reviewed, 2018)Preclinical research has demonstrated that nanoparticles and macromolecules can accumulate in solid tumors due to the enhanced permeability and retention effect. However, drug loaded nanoparticles often fail to show increased ... -
The Effect of Sonication on Extravasation and Distribution of Nanoparticles and Dextrans in Tumor Tissue Imaged by Multiphoton Microscopy
Yemane, Petros Tesfamichael; Åslund, Andreas; Sæterbø, Kristin Grendstad; Bjørkøy, Astrid; Snipstad, Sofie; van Wamel, Annemieke; Berg, Sigrid; Mørch, Ýrr Asbjørg; Hansen, Rune; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Journal article; Peer reviewed, 2018)Ultrasound (US)and systemic administration of microbubbles (MBs)have been shown to improve the delivery of drugs and nanoparticles (NPs)to tumor tissue. A better understanding of the mechanisms is crucial for effective ... -
Ultrasound and magnetic resonance imaging for group stratification and treatment monitoring in the transgenic adenocarcinoma of the mouse prostate model
Fagerland, Stein-Martin Tilrum; Hill, Deborah Katherine; van Wamel, Annemieke; Davies, Catharina de Lange; Kim, Jana (Journal article; Peer reviewed, 2020)Background:The transgenic adenocarcinoma of the mouse prostate (TRAMP) is a widelyused genetically engineered spontaneous prostate cancer model. However, both thedegree of malignancy and time of cancer onset vary. While ... -
Ultrasound Improves the Delivery and Therapeutic Effect of Nanoparticle-Stabilized Microbubbles in Breast Cancer Xenografts
Snipstad, Sofie; Berg, Sigrid; Mørch, Ýrr Asbjørg; Bjørkøy, Astrid; Sulheim, Einar; Hansen, Rune; Grimstad, Ingeborg; van Wamel, Annemieke; Maaland, Astri Fjelde; Torp, Sverre Helge; Davies, Ruth Catharina de Lange (Journal article; Peer reviewed, 2017)Compared with conventional chemotherapy, encapsulation of drugs in nanoparticles can improve efficacy and reduce toxicity. However, delivery of nanoparticles is often insufficient and heterogeneous because of various ...
