yes it does. Spell pen effects magic damage and madreds does magic damage. If I ever get back to playing AP Kog' maw I still like to toss this item on him just because madreds along with bio-arcane barrage and some AP and Magic Pen makes him hit really hard and you get a little bit of attack speed along with a rage blade you are still a comparable beast to AD Kog maw.
