  • Conference Provides Collaboration Opportunities for Those Pursuing Effective Therapies for Patients

    Partnering for Cures Conference Provides Collaboration Opportunities for Those Pursuing Effective Therapies for Patients Faster

    FasterCures, the Washington, DC-based center of the Milken Institute, convened the second annual Partnering for Cures, December 14-15, 2010 to advance the goal of bringing effective therapies to patients faster.  Partnering for Cures brought together all the sectors engaged in the research enterprise to facilitate the strategic collaborations needed to turn scientific discoveries into accessible therapies.

    For the second year, a representative of the Focused Ultrasound Surgery Foundation attended this dynamic meeting.  More than 800 people were in attendance, representing innovators, investors, non-profit leaders, government agencies and decision- makers.  It was a wonderful opportunity to share MRgFUS with a group so dedicated to accelerating medical solutions for deadly and debilitating diseases.  While an enormous amount of progress is being made in finding effective MRgFUS therapies for cancer, Essential Tremor, Parkinson’s disease and a variety of other conditions, many leaders dedicated to finding cures for these same diseases are unaware of the promise MRgFUS has in providing positive outcomes.  They are eager and ready to learn.  Of course, there was much discussion about how the FDA and NIH can and is changing to quicken the advancement and delivery of new therapies and treatments.  The quality of the speaker and relevance of the topics discussed speak volumes.  To read more, visit the symposium website at http://fastercures.org/index.cfm/OurPrograms/Partnering_for_Cures.

  • Comparative effectiveness research conference details

    The National Institutes of Health (NIH) and the Agency for Healthcare Research and Quality (AHRQ) are co-sponsoring a free conference on Methodological Challenges in Comparative Effectiveness Research.

    “Comparative effectiveness research (CER) is increasingly important to the advancement of MR-guided focused ultrasound,” says Joy Polefrone, Ph.D., director of the Foundation’s FUS-Targeted Drug Delivery initiative. CER compares existing treatment options to determine which is most effective in different types of patients and circumstances. 

    “Treatments for uterine fibroids – the first FDA-approved indication for MR-guided focused ultrasound – are already being addressed by an AHRQ stakeholder group. The group has developed protocol recommendations to address concerns about these treatments,” Polefrone notes. “Future applications of MR-guided focused ultrasound will undergo CER assessment in the U.S., making it important to understand this process and its impact on clinical use.”

    Scheduled for December 2-3, the conference will be held at the NIH Clinical Center in Bethesda, Maryland.  It will address a variety of important questions about comparative effectiveness research that face U.S. researchers, care providers, health systems, and patients. In particular, the conference will explore a number of case studies challenging the kinds of research, methods and analyses that should be used to address limitations in current evidence for interventions and tests being examined by decision-making bodies

     

    Topics include:

    • Comparative effectiveness of surgical and radiotherapy treatments for prostate cancer: Best methods for studying multilevel heterogeneous effects.
    • Comparative effectiveness of medical and surgical treatments for stable ischemic heart disease within subgroups of patients and in the face of rapidly evolving treatments.
    • Comparative effectiveness and costs of imaging strategies for diagnosing and monitoring patients with cancer.
    • Evaluation of two high-profile comparative drug safety cases: Aprotinin and Rosiglitazone.
    • Challenges of designing a “Learning Healthcare Systems” for Comparative Effectiveness Research. 

     

    In addition to these case-based discussions, consumers, economists, methodologists, policymakers and statisticians will present two additional sessions:

    • Methods for Addressing Confounding in Observational Studies.
    • Value of Information Techniques for Setting Research Priorities.

  • Zürich Transcranial FUS Results Presented at Annual Meeting

    Professor Daniel Jeanmonod faced a packed meeting room at the Philadelphia convention Center on May 3 when he presented his much-anticipated results treating 12 patients in Zürich using transcranial MR-guided focused ultrasound (TcFUS). Many neurosurgeons in the audience at the Stereotactic and Functional Neurosurgery Session of the 2010 annual meeting of the American Association of Neurological Surgeons were there mainly for his presentation.

    He reported on 18 ablative lesions performed in 12 patients using transcranial central lateral thalamotomy with the Exablate 4000 (Insightec Ltd, Haifa). All patients suffered from chronic therapy-resistant neuropathic pain, including some who had failed prior radiofrequency lesioning.   Real-time MR image monitoring (thermometry) was performed in awake patients, allowing for on-line control of targeting parameters, precision and safety.

    His work confirmed the high level of precision in lesion placement (< 1.0 mm) that had been previously reported (Martin E. et al., Annals of Neurology 66(6):858-861, 2009).  Skull heating was minimal.

    Peri-lesional edema appeared on MRI within 48 hours, but was resolved at the time of the 1-month MRI.

  • Third International Symposium on Focal Therapy and Imaging of Prostate and Kidney Cancer

    Third International Symposium on Focal Therapy and Imaging of Prostate and Kidney Cancer. Fairmont Hotel, Washington, DC.  February 24-27, 2010.

    Duke Comprehensive Care Cancer Center, Sponsor

    Existing ultrasound-based technologies for treatment of prostate cancer lack accurate real-time thermal feedback during therapy, so treatment is protocol-based rather than patient-specific. Prostate motion during focal treatment is a significant issue that must be addressed.  MRI-guidance (for FUS or laser therapy) continues to offer distinct advantages.

    Thought leaders in urology emphasize applying focal therapy to men who truly need treatment, citing some question about the level of accurate characterization by imaging and multi-site biopsies. The option of reliable focal therapy is in fact driving the movement towards more efficient characterization.  It is important to separate out those men who truly have “low risk disease” and might be managed safely by active surveillance.

  • Thilo Hoelscher, M.D. exploring use of FUS to treat ischemic stroke

    Trained as a neurologist, Thilo Hoelscher, M.D., has travelled a long way from his native Germany and his early clinical experiences at that country’s first stroke unit. Now an assistant professor in the Departments of Radiology and Neurosciences at the University of California San Diego, he is Director of its Brain Ultrasound Research Laboratory and working once again on the forefront of medicine.

    As a researcher and clinician, Hoelscher has extensive experience in using transcranial ultrasound as a diagnostic tool. In 2007, he learned about high intensity focused ultrasound and became intrigued with its potential to treat the human brain. Since then, he has completed hundreds of preclinical experiments with FUS and concentrated on developing therapies based on a clot-busting technique, transcranial sonothrombolysis. He recently received a multi-million dollar grant from the National Institutes of Health to study sonothrombolysis as a treatment for ischemic stroke.

    Hoelscher, who received a FUSF fellowship in 2009, expects to begin pilot clinical trials in 2011 using FUS to treat stroke and believes success is inevitable. “Once it is approved for use in patients, FUS will be without equal – it will have no competition. In treating ischemic stroke, for example, it will dissolve blood clots and restore blood flow within seconds. Drugs like tPA won’t be necessary,” he says.

    Hoelscher’s work has moved beyond exploring the thermal ablative capabilities of FUS to assessing its use in precise drug delivery and its ability to induce cellular mechanisms.

    Noting that the pace of FUS research is accelerating, he says. “Our work has been booming during the last six to eight months. Everything has started to progress rapidly. Researchers from all over the place are interested in focused ultrasound. Ideas and new collaborations are popping up everywhere.”

  • Third Autumn School on Therapeutic Ultrasound – Attendee Reports

    On September 28, 2009, more than 75 attendees trekked to Cargese, Corsica, for the Third Autumn School on Therapeutic Ultrasound.  The School was directed by Gail ter Haar, PhD, of the Institute of Cancer Research, and Mathias Fink, PhD, founder of the Institut Langevin in Paris.

    The organizational heavy lifting was undertaken by two full-time researchers at the Institut Langevin, Jean-François Aubry and Jean-Luc Gennisson, who did an exceptional job of bringing together attendees from 10 countries, including 19 faculty members.  For the students, it was an incomparable opportunity to learn from the leaders in the rapidly emerging field of therapeutic ultrasound.  The lectures began with an introduction to the physics and biophysics to build the foundation for understanding the technical aspects of therapeutic ultrasound, followed by individual lectures on topics ranging from commercial devices for treating prostate cancer to emerging applications for focused ultrasound.  – Joy Polefrone, PhD, FUSF

    The small town of Cargese, with only 290 inhabitants, allowed all of the sage and budding scientists in this newly emerging field to delve into the current technology, assess new developments as well as systems under development, and freely explore a wide range of biological and engineering challenges to FUS. The setting afforded ample opportunities for participants to meet with faculty while looking out over the cliffs, beaches, and Mediterranean sunsets.  Where or when the next FUS school for scientists will take place is not yet known – France, London, or the USA.  But hopefully it will afford opportunities to delve into many topics and to appraise the latest developments in the field with the same success experienced in Cargese in 2009. Stanley H.

  • World Society of Stereotactic and Functional Neurosurgery Report

    The World Society of Stereotactic and Functional Neurosurgery (WSSFN) had its 15th Quadrennial Meeting in Toronto, Canada May 24-27, 2009 (Detailed program).  More than 500 functional neurosurgeons from around the world convened to discuss their latest findings.  As a group, functional neurosurgeons have the highest percentage of interest in MRgFUS of any group of clinical physicians (virtually 100%).

    There has been a surge in interest using deep brain stimulation (DBS) for neuromodulation in functional neurosurgery over the last decade.  The main limitations of DBS for movement disorders, pain and behavioral disorders are cost in both money and time, and the necessity of a neurosurgical operation that entails some risk of hemorrhage, infection, mechanical failure, neurologic damage, etc. One tremendous advantage of MRgFUS is the non-invasive nature of the technique. Any form of lesioning, including MRgFUS, gains significant advantage through targeting techniques that assure a safe, effective lesion location.  MRgFUS offers distinct advantages over other techniques through MR thermometry (visualization of the actual energy focus prior to lesioning) and neurophysiological assessment through transient neuromodulation effects.  This counters the main advantage of DBS, which is its reversibility in the face of a misplaced lead (with adverse neurologic symptoms.)

    Kyoshi Namba M.D. (Breastopia Namba Hospital, Japan) presented a very comprehensive and optimistic review of the clinical trials investigating breast cancer treatment with MRgFUS. He started by applauding the remarkable progress in breast conserving treatments for breast cancer, and predicted that focused ultrasound would be the ultimate minimally invasive treatment which avoids scarring, a possibility which he, as a breast surgeon, is keen to embrace.

    Dr Namba described the importance of ongoing monitoring of disease using MRI during the pre-operative phase during which chemotherapy and radiation are utilized. The great benefit of the MRI modality is that it allows the rapid identification of non-responders and switching to other treatments. (References given: Lehman and Furusawa).

    Like MRI, focused ultrasound is seen as a conservative treatment as it does not use ionizing radiation and does not preclude other more aggressive therapy to follow. Since 2002 it has been studied as comparison to lumpectomy in breast cancer, and integrated into the breast healthcare system in his hospital in Japan.

  • Society for Thermal Medicine Conference Summary – MR guided High Intensity Focused Ultrasound Stands Out

    Founded in 1986 by researchers in the area of thermal therapy, the Society for Thermal Medicine has facilitated a forum for discussion of research for more than 20 years. The Society’s 2009 Annual Meeting was held in Tucson, Arizona, on April 3–7, with a program jam-packed with presentations on research topics that included Targeted Drug Delivery and Liposomes, Thermal Effects on the Immune System and the Tumor Microenvironment, and even a full session on MRI-guided Focused Ultrasound. 

    Targeted Drug Delivery is a research area the Foundation has consistently predicted will have tremendous potential when coupled with Focused Ultrasound. In fact, we recently funded a research project to support work by Katherine Ferrara’s group at the University of California at Davis that aims to create and validate clinically relevant ultrasound-enhanced drug delivery. One of Dr. Ferrara’s colleagues, Dustin Kruse, PhD, presented related work at STM, and we look forward to seeing continued success from Ferrara’s lab, aided by Foundation resources.

  • FUSF Funds Targeted Drug Delivery Research Project

    "Creation and Validation of a Clinically‐relevant Ultrasound‐enhanced Drug Delivery Strategy"

    Katherine W. Ferrara, Ph.D., University of California, Davis

    Summary: The primary purpose of this study is to determine the exact protocol for maximizing ultrasound-enhanced accumulation of drug in tumor and surrounding tissue. The study will use a system which precisely quantifies full-body drug biodistribution to measure drug accumulation enhancement in relation to low-mechanical index ultrasound.  A separate system will precisely control the ultrasound parameters and the resulting heating. These methods will be combined to optimize the ultrasound dose, measure accumulation and distribution of drug, and to assess efficacy.  This in-vivo study will utilize liposomal cisplatin and PET imaging. The award is for $100,000, to commence Q2 2009.

  • Opening the Blood-Brain Barrier After Whole-Brain Radiation Therapy

    Observed Effects of Whole-Brain Radiation Therapy on Focused Ultrasound Blood–Brain Barrier Disruption

    Nathan McDannold’s group at Brigham and Women’s Hospital and Harvard Medical School recently completed a study to determine whether prior brain irradiation affected outcomes when opening the blood-brain barrier (BBB) with focused ultrasound and microbubbles. This preclinical study in a mouse model tested whether BBB opening varied between brain tissue that was exposed to 3 grays of radiation for 10 consecutive days and non-irradiated tissue. The microbubble-assisted BBB opening was performed unilaterally so the contralateral side could serve as a control. Did prior radiation of the brain act as a sensitizer for BBB opening?
