FO to be pilot flying. After cleared to line up and wait I stopped the aircraft and stated 'Your aircraft; parking brake set' FO advance thrust levers to TOGA without releasing parking brake. I stated; 'My aircraft; reject' and rejected the takeoff. There was no indicated airspeed. After following all reject procedures; we taxied clear. Followed up with Volume X and QRH. Re- accomplished Before takeoff checklist and proceeded to ZZZ1.The FO stated he did not hear me state 'parking brake set' He also briefed me previously that he hadn't flown in a while so that may have [been] a contributing factor.This may have been a communications failure. I think it should be emphasized that the park brake be set anytime the aircraft is not in motion. This is the safest procedure to ensure unwanted aircraft movement.
Air carrier Captain reported the First Officer advanced thrust levers to TOGA without releasing the parking brake.
