Constantin Coussios, PhD, Recognized in Queen’s Birthday Honours List

Published:
Professor Constantin Coussios Constantin Coussios, PhD, has been appointed as an Officer of the Most Excellent Order of the British Empire (OBE) for his services to biomedical engineering. The award was recently announced in the 2022 Queen’s Birthday Honours List as part of Queen Elizabeth II’s Platinum Jubilee celebrations. Prof. Coussios became the University of Oxford’s first Statutory Chair in Biomedical Engineering in 2011 and has served as Director of the Institute of Biomedical Engineering since 2016. He holds BA, MEng, MA, and PhD degrees in Engineering from the University of Cambridge.In 2004, he moved to Oxford to take up the very first faculty position in biomedical engineering, following postdoctoral appointments with Prof. Christy Holland in Cincinnati and Prof. Ron Roy in Boston. At Oxford, he founded and leads the Biomedical Ultrasonics, Biotherapy and Biopharmaceuticals Laboratory (BUBBL), a multidisciplinary research and training environment for combinational engineering of biology, chemistry, and medical devices to improve non-invasive therapies and drug delivery under a single roof.He has worked in therapeutic ultrasound across both thermal and cavitational therapies for the past 20 years, most notably pioneering passive acoustic mapping for cavitation-based treatment monitoring with his student Miklos Gyongy in 2008 and developing the first generation of solid gas-stabilizing cavitation nucleation agents with then post-doctoral researcher (and now Oxford professor) James Kwan in 2013.Beyond basic research and discovery, he has led and co-led several clinical studies in the field of focused ultrasound, including a first-in-human trial of focused ultrasound-triggered drug delivery from thermosensitive liposomes (Lancet Oncology 2018) that could make a significant difference in the way that liver cancer is treated.Prof. Coussios was also the lead academic founder of two focused ultrasound companies, OxSonics Ltd. and OrthoSon Ltd. OxSonics is currently conducting clinical trials of cavitation-enhanced drug delivery in patients with metastatic colorectal cancer, and OrthoSon is developing a percutaneous minimally invasive technique to treat lower back pain and restore spinal function.He says, “No honour has ever surprised me more. I am extremely grateful to my amazing students and academic colleagues within the University, to my fantastic co-workers within OrganOx*, OxSonics, and OrthoSon, and to the extraordinary Oxford biomedical innovation ecosystem for enabling the generation and successful translation of new engineering and cross-disciplinary technologies from bench to bedside.” Related ArticlesCompany Profile: OxSonics Therapeutics January 2022New Clinical Trial of Focused Ultrasound–Enhanced Chemotherapy for Pancreatic Cancer July 2021Meeting Report: Therapeutic Ultrasound in Oncology Symposium May 2021Investigator Profile: Constantin Coussios, PhD August 2018*OrganOx is a company dedicated to revolutionizing organ preservation prior to transplantation, and received Post-Marketing Authorization approval by the FDA for its metra normothermic liver perfusion device in December 2021.

Skin Cancer Clinical Trial Begins in Denmark

Published:
A new dermatology clinical trial (NCT05133427) that uses focused ultrasound to treat non-nodular or recurrent basal cell carcinoma (BCC) has begun in Denmark. Unlike melanoma, BCC is a common type of skin cancer that is found in areas of the skin exposed to the sun. Although it is rarely fatal, it is the most common cancer worldwide. Traditional treatments include various types of surgical removal, radiation, photodynamic therapy, or topical medications. The principal investigator is Professor Joergen Serup, MD, a dermatologist who will lead the study at Bispebjerg and Roskilde Hospitals, part of the University of Copenhagen. Up to 40 participants will be treated with the TOOsonix System ONE-M device. Each treatment consists of one to two minutes of HIFU applied to the affected area of skin. “HIFU has a significant potential for future use in treatment of BCC and other dermatological conditions,” said Prof. Serup. “In experimental work, it has already been indicated that the device has important practical and resource-saving advantages over photodynamic therapy, which is a leading therapy in superficial and early-stage BCC. Noteworthy is the reduced pain-level during treatment…The method can work well in hospitals as well as private practice settings.” No anesthesia or special after care is needed beyond regular follow-up visits for the first year after treatment. Initial safety and cure rate data will be reported after all participants have been followed for the first three months.

Focused Ultrasound for Metastatic Colorectal Cancer: First Patient Enrolled in Clinical Trial

Published:
Oxford-based OxSonics Therapeutics announced that the first patient was dosed in a clinical trial evaluating their SonoTran platform for treating colorectal cancer that has spread to the liver. The SonoTran platform is designed to actively pump unmodified oncology drugs at the site of solid tumours to enhance their effectiveness. Nearly 50 patients with liver metastases will be enrolled at Oxford University Hospitals. Key Points Oxford-based OxSonics Therapeutics announced that the first patient was dosed in a clinical trial evaluating their SonoTran platform for treating colorectal cancer that has spread to the liver. The SonoTran platform is designed to actively pump unmodified oncology drugs at the site of solid tumors to enhance their effectiveness. Nearly 50 patients with liver metastases will be enrolled at Oxford University Hospitals. Oxford-based manufacturer OxSonics Therapeutics announced that the first patient was dosed in a clinical trial evaluating the use of their SonoTran® platform for enhancing the treatment of colorectal cancer that has spread to the liver. The SonoTran® platform is comprised of OxSonics’ proprietary SonoTran Particles and the Sonotran® System – a noninvasive ultrasound device. The particles carry a pre-formed, stabilized gas bubble. When exposed to focused ultrasound via the SonoTran System, the particles expand and collapse to create sustained levels of inertial cavitation at the site of the tumor. This mechanical micro-pumping effect is intended to actively enhance the transport of unmodified anti-cancer drugs into and throughout solid tumors. In addition, the SonoTran System incorporates OxSonics’ ‘see-as-you-treat’ technology enabling mapping and monitoring of treatment on screen in real time. OxSonics CEO and co-founder Dr. Colin Story commented: “Striving to deliver smarter and better therapies to help patients tackle tough-to-treat cancers is at the heart of everything we do, so we’re delighted that SonoTran is now being evaluated clinically. After more than ten years of innovative research at the University of Oxford’s Institute of Biomedical Engineering, followed by a further eight years of pre-clinical development by the world-leading multi-disciplinary team at OxSonics, we now enter a new and very exciting chapter in OxSonics’ evolution.” In this trial, researchers are using the SonoTran System to enhance the chemotherapy treatment of colorectal cancer that has spread to the liver. The study contains three cohorts. Cohort 1 patients will have undergone chemotherapy treatment and will receive one SonoTran ultrasound treatment and one injection of the SonoTran Particles to assess safety. In Cohort 2, patients who are about to have their tumors removed surgically will receive low doses of chemotherapy drugs, and half of the cohort will also receive SonoTran Particles and ultrasound. The tumors that are removed will be examined to determine the concentrations of drugs within the tissue and note if the cohort that received the SonoTran procedure had elevated levels of drug compared to those that did not undergo the ultrasound procedure. Cohort 3 patients will have not yet received treatment for their tumors; therefore, they will receive repeated cycles of standard chemotherapy drugs, and half of them will also receive SonoTran Particles and SonoTran ultrasound. Tumor responses will be measured and compared. The study is led by Professor Rachel Kerr in the Department of Oncology at the University of Oxford. OxSonics and the National Institute for Health Research (NIHR) are providing the support and funding for the study. Patients are now being enrolled at Oxford University Hospitals, and those interested in learning more are encouraged to contact David Thompson at OCTO-CEeDD@oncology.ox.ac.uk.
