1. An assembly for a drug delivery device, the assembly being arranged to operate in two distinct modes, a priming mode starting from a pre-priming state and a dispense mode operating in a post-priming state, the assembly having a distal end and a proximal end, which are spaced apart in the direction of an axis, the assembly comprising a dose member, an actuating member, and a piston rod which is configured to act on a bung of an assembled cartridge containing the drug, wherein in the pre-priming state the actuating member is configured to be moved in a distal direction by a user such that the distal movement of the actuating member causes a movement of the dose member and wherein the movement of the dose member causes a movement of the piston rod and, wherein in the post-priming state the dose member is configured to be moved by a user without causing a movement of the actuating member in order to perform a set and dispense action of the drug delivery device.
