Desmoid tumours are rare, locally aggressive soft-tissue tumours that are challenging to manage, due to lack of approved therapies, and variable presentation. Dr Bernd Kasper (Universitätsmedizin Mannheim, Mannheim, Germany) joins touchONCOLOGY to discuss the phase 3 DeFi study, a global randomized, double-blind, placebo-controlled trial in adults with progressing desmoid tumours. The trial investigates nirogacestat, a novel oral gamma secretase inhibitor, that has shown antitumour activity in patients with desmoid tumours.
The abstract entitled ‘DeFi: A phase III, randomized controlled trial of nirogacestat versus placebo for progressing desmoid tumors‘ Abstract LBA2, was presented at European Society for Medical Oncology (ESMO) 2022.
