Low Intensity Contact Ultrasound Implant 

Clinical Developments

A phase 1/2a clinical trial is currently in progress to study the transient opening of the blood-brain barrier (BBB) using the SonoCloud® during chemotherapy administration in patients with recurrent glioblastoma.

This study is a prospective multidisciplinary single-arm mono-center study that is being performed by the departments of Neurosurgery and Neuro-Oncology at the Hospital Pitie Salpetriere. The study sponsor is l’Assistance Publique des Hôpitaux de Paris.

The study addresses patients with gliobastoma that have experienced recurrence after initial standard of care treatments and who are eligible for carboplatin chemotherapy. Patient inclusion is discussed on a case by case basis during multidisciplinary department meetings.

The goal of this Phase 1/2a clinical study is to temporarily disrupt the BBB using low intensity pulsed ultrasound during chemotherapy sessions with carboplatin, with the goal of increasing the concentration of chemotherapeutic agent in the brain tissue.

    CarThera closes €9M ($10.3M) Series B funding round

    €9M ($10.3M) was raised with three institutional investors, Panakès Partners, Sham Innovation Santé (advised by Turenne Capital) and Supernova Invest via its fund Supernova 2, as well as Group Arnault and historical investors. The proceeds will be used to further advance the SonoCloud technology and develop the clinical pipeline of the company. A multi-center study has already been launched in France and in the US to evaluate the SonoCloud-9 device, a new generation of implant with nine ultrasound emitters, in patients with recurrent glioblastoma. The company also has an on-going clinical study with the SonoCloud-1 device in patients with Alzheimer’s disease and one planned for patients with brain metastases.

    ASCO 2018: CarThera presents promising preliminary efficacy data for treating recurrent glioblastoma

    Preliminary data from the first clinical trial of the company’s intracranial ultrasound implant, SonoCloud®, show a good safety profile and promising trends in overall survival.

    Dr. Ahmed Idbaih, AP-HP principal investigator of the Phase 1/2a clinical trial (NCT02253212) presented a preliminary analysis of the data from 21 glioblastoma patients who received 65 SonoCloud® treatments. Overall Survival was increased from 8.5 to 12.9 months in patients who had SonoCloud®-induced BBB opening.

    May 2018 – CarThera will participate to BIO 2018 in Boston

    CarThera will participate to the BIO International Convention in Boston on June 4-7 to meet with global biotech and pharma leaders and showcase its SonoCloud device.
