Treatment

Therapeutic ultrasound for brain disorders

SONOPROBE

At CarThera, we have by-passed the problem of the skull bone by taking advantage of the necessary clinical step of tumor biopsy before any treatment. No clinician worldwide can envision beginning a chemotherapy or radiotherapy treatment without a previous histological diagnosis. We have designed and developed a probe that is able to emit high intensity ultrasound that can be inserted within the tumor as a biopsy needle under local anesthesia.  The probe performs not only the necessary biopsy but also the ultrasound treatment of the tumor in the same procedure under real-time MRI control.

 

SONOCLOUD

Ultrasound emitted at a lower intensity is also able to interact with the biological tissue without destroying it. Using low-intensity pulsed ultrasound, it is possible to temporarily make the blood vessels more porous to drugs. In the brain, the vessels are particularly tight (Blood-Brain Barrier or BBB), preventing the penetration of chemotherapy in the brain and significantly reducing its effectiveness.

At CarThera®, we have developed an implantable medical device containing a low intensity ultrasound transducer, the SonoCloud®, which is able to temporarily open the blood-brain barrier. At each chemotherapy session, the BBB can be opened in order to optimize the penetration of the chemotherapy in the brain while reducing the side effects in the rest of the body.

    CarThera presented data from phase 1/2a study at 2017 ASCO annual meeting

    June 2017 – Dr. Ahmed Idbaih, AP-HP principal investigator of the Phase 1/2a clinical trial (NCT02253212) on ultrasound induced Blood-Brain Barrier opening revealed preliminary safety and efficacy data at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

    The clinical data from the trial involving 21 patients with recurrent glioblastoma, who have all been treated with SonoCloud® low-intensity pulsed ultrasound in a total of 65 sessions, have been shared with more than 30,000 oncology professionals from around the world.

    CarThera secures €5.7 million in funding for its DOME project

    October 12, 2016 – CarThera has received a grant of €5.7 million ($6.4m) for its DOME project. The funding was awarded under the call for proposals ‘Structuring R&D Projects for Competitiveness’ from France’s ‘Investments for the Future Program’, led by the General Investment Commission and run by Bpifrance.

    The grant will finance our SonoCloud Phase 2b/3 study in glioblastoma that will involve around 200 patients at centers in Europe and the United States. It will also fund a number of exploratory studies, including one on Alzheimer’s disease, building on the findings from the Phase 1/2a study that paved the way for a broader array of clinical indications.
