Manufacturer Narrative

Novocure opinion is that the contribution of the array placement to wound dehiscence cannot be ruled out.Contributing factor for wound dehiscence in this patient include: concomitant bevacizumab (vegf inhibitor which carries a black box warning for wound healing complications.Source: bevacizumab prescribing information), prior dexamethasone use (impaired wound healing and increased risk of infection are listed as side effects.Source: dexamethasone prescribing information), prior radiation, underlying cancer disease, and prior surgery affecting skin integrity.Wound dehiscence 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 the optune/tmz arm of the trial (<1%) only.

Event Description

A 78-year-old female with newly diagnosed glioblastoma (gbm) started optune therapy on (b)(6) 2020.Novocure was informed on (b)(6) 2023, that the patient had plastic surgery scheduled the following day for a chronic open sore on the surgical resection site (last surgical resection (b)(6) 2020).Optune therapy was temporarily discontinued.In the photo provided there appeared to be a wound dehiscence on the surgical resection scar.On (b)(6) 2023, the patient reported the surgeon cleared her to resume optune therapy.After several attempts of contact, the prescribing physician did not provide a causality assessment for the event.

Manufacturer Narrative

On april 26, 2023, additional information was discovered during review of an available medical record.The patient reported an open sore adjacent to the surgical resection scar on (b)(6) 2023.The patient underwent operative debridement, removal of periosteum to outer cortex of calvaria with removal of cranial hardware, and complex closure by plastic surgery on (b)(6) 2023.It was noted the sore developed in an area that occasionally optune adhesive covered.As the incision was near the crown of the head and healing well, optune therapy was able to be resumed by adjusting the arrays around the affected area.
