Chinese trial reportedly found nano-carbon iron injections halted tumor growth in 84.2% of patients with advanced, refractory cancers

Sputnik says a first-in-human trial at West China Hospital's Cancer Center tested direct injections of a nano-carbon iron complex in patients with advanced, refractory cancers. It reported that tumor growth halted in 84.2% of patients and reversed in some cases. In October 2026, Sputnik said a Phase II trial combining the treatment with radiotherapy was underway at ten Chinese hospitals.
