Manufacturer Narrative

Novocure opinion is that the contribution of the array placement to wound dehiscence and wound infection cannot be ruled out.Contributing factors for wound infection and wound dehiscence in this patient include: prior dexamethasone use (impaired wound healing and increased risk of infection are listed as side effects.Source: dexamethasone prescribing information), concomitant bevacizumab (carries a black box warning for wound complications.Source: bevacizumab prescribing information), prior radiation, underlying cancer disease, and prior surgery affecting skin integrity.Wound infection is an expected event with device use and was reported as an adverse event in the ef-14 trial of optune together with temozolomide (tmz) compared to tmz alone in patients with newly diagnosed gbm in both arms of the trial (<1% and <1% in optune/tmz and tmz arms respectively).Wound dehiscence was reported in the ef-14 trial in the optune/tmz arm of the trial (<1%) only.
