PARIS – A Russian research consortium has discovered that coating magnetic nanoparticles with a non-magnetic silica shell significantly decreased the viability of cancer cells in a low frequency alternating magnetic field. This discovery may augur new therapeutic prospects for nanotechnology combined with medical imaging.

TORONTO – Radialis Medical Inc. has submitted FDA premarket notification for a positron emission tomography system (PET) that targets specific organs for low dose imaging and may be flexible enough to assess many different diseases. The Radialis PET camera is under clinical investigation at Toronto’s University Health Network and Princess Margaret Cancer Center for its ability to assess anomalies in breast cancer.

A lack of toxicity and the shrinking of tumors were at the heart of new interim data produced from a two-stage phase II study by Relay Therapeutics Inc. The company reported that the oral small molecule RLY-4008, designed to elicit responses across a broad spectrum of resistance mutations and in multiple tumor types, selectively inhibited fibroblast growth factor receptor (FGFR) 2 in ways that are not limited by off-target toxicities of hyperphosphatemia (FGFR1) and diarrhea (FGFR4).
