Maybe, but not for a very long time. You'd have to develop an otherwise inert enzyme that can go through cell membranes and spread to every cell in the body. Theoretically this would be feasible using a retro virus that can infect every cell and instruct it to produce the enzyme but we're basically just getting our feet wet with genetic engineering research that is bound to take decades or centuries to get to that point.
Dialysis wouldn't do a thing since most of the toxic molecules arent going to be in the blood plasma.
