Manufacturer Narrative

Novocure medical opinion is that a contribution of the array placement to the event cannot be ruled out.Other contributing factors for skin erosion in this patient include: concomitant bevacizumab (vegf inhibitor which carries a black box warning for wound healing complications.Source: bevacizumab prescribing information), concomitant dexamethasone (impaired wound healing is listed as a side effect.Source: dexamethasone prescribing information), underlying cancer disease, prior radiation and prior surgery affecting skin integrity.Skin erosion leading to vp shunt revision was not reported in the ef-11 pivotal trial in recurrent glioblastoma or in the commercial program to date.The optune instructions for use cautions that use of the device with implanted medical devices in the brain may lead to tissue damage.Scalp necrosis is a known complication of vp shunt placement.Vp shunt complications have been reported in the literature as occurring in 11.8% of patients with brain tumors, with 6.7% of patients requiring shunt removal (source: nigim et al, oncology, 2015, 3:1381-1386).
