Safety and Efficacy of Sonocloud Device Combined With Nivolumab in Brain Metastases From Patients With Melanoma

Summary

Anti PD-1 monoclonal antibodies (nivolumab and pembrolizumab) alone or in association with antiCTLA4 (Ipilimumab) are established as indisputable treatment of metastatic melanoma, with unprecedented overall survival, and are indicated for first-line treatment including patients with BRAF mutation. Given their high molecular weight, their penetration in the brain sanctuary is uncertain and relies on disruption of the Blood Brain Barrier (BBB) which occurs occasionally. SonoCloud® is an implantable device delivering low intensity pulsed UltraSound (US). Along with systemic injection of an US resonator, SonoCloud® demonstrated safe and efficient at repetitively opening the BBB. The investigators anticipate that BBB opening could help at increasing brain penetration of monoclonal antibodies and potentially boosting immunity in the brain. This could translate in controlling brain disease with the same magnitude as for extra-cranial disease. This would also open avenues for optimizing the treatment of brain metastases in combination with checkpoint inhibitors in many other cancers.
