Carthera SA raised €37.5 million (US$40 million) in a series B funding round that will allow the company to embark on the first pivotal trial of its Sonocloud technology. The Sonocloud-9 is the only implantable ultrasound device that can repeatedly open the blood-brain barrier and deliver effective treatment in patients with recurrent glioblastoma, Frédéric Sottilini, CEO of Carthera, told BioWorld.

Carthera SA reported results from a pilot clinical trial to evaluate the safety and efficacy of its Sonocloud technology in patients with mild Alzheimer’s disease (AD). The results, published in Alzheimer’s Research and Therapy, show early promise of the treatment in reducing the amyloid load of AD and potentially other neurological conditions as well as to stimulate neurogenesis and improve cognitive performance.

While several companies are looking to help recurrent glioblastoma patients, Carthera SAS has taken a step forward by bringing its Sonocloud-9 device into a phase I/II clinical trial. Northwestern University in Chicago will collaborate with the company in the trial, which is expected to enroll up to 39 patients. The first patient already has been treated.

PARIS – Carthera SAS, of Paris, has obtained a $2.4 million grant and $12.5 million equity investment from the European Innovation Council (EIC) for the development of its ultrasound-based medical device for treating glioblastoma.

Lantheus Holdings Inc., of North Billerica, Mass., has entered a strategic collaboration with Paris-based Carthera SAS for the use of its microbubbles in combination with Carthera’s investigational Sonocloud system. The implantable device is in development for the treatment of recurrent glioblastoma, a fast-growing brain tumor with a post-diagnosis median survival of just 15 months. The new deal furthers two of Lantheus’ strategic goals, finding new applications for its microbubbles and expanding its footprint in oncology.
