logo-carthera CARTHERA About Us

Carthera® is a spin-off from AP-HP, Greater Paris University Hospitals, the largest hospital group in Europe, and Sorbonne University. The company leverages the inventions of Professor Alexandre Carpentier, lead neurosurgeon at AP-HP, who has achieved worldwide recognition for his breakthrough developments in treating brain tumors.

Founded in 2010, Carthera® is headquartered in Lyon. The company also has offices at the Brain Institute (Institut du Cerveau, ICM) in Paris and a US subsidiary based in Boston. It works closely with renowned academic institutions, like INSERM, Sorbonne University, AP-HP, Northwestern University, UCSF.

Carthera® is a clinical-stage company with its SonoCloud® implant that temporarily opens the blood-brain barrier (BBB). SonoCloud® is presently being investigated in several clinical trials in oncology as well as in neurodegenerative diseases.

The company is certified in accordance with ISO 13485 for the design, the development and the manufacturing of these medical devices.

Research & Development 

The lack of brain vessel permeability limits the impact of therapeutic agents for the treatment of brain tumors like glioblastoma. Combined with the SonoCloud® device, therapeutic agents could be much more effective, ultimately improving the treatment of glioblastoma and other brain diseases.
