Medical device coatings are provided that simultaneously release a therapeutic agent at different rates from different portions of the medical device coating. In a first embodiment, medical device coatings are provided that include particles comprising a therapeutic agent with two or more different particles sizes within a single layer on a surface of the implantable device. In a second embodiment, medical device coatings are provided having a higher concentration of the therapeutic agent in a first region of the coating than in a second region of the coating. In a third embodiment, medical device coatings are provided that are formed by certain coating processes wherein the droplet size of a spray coating solution is changed during the coating process. These coating processes preferably include applying a solution comprising a therapeutic agent and a suitable solvent to a surface of an implantable medical device. In a fourth embodiment, methods of treatment are provided that include implanting a coated medical device.

A method of treating a subject with cancer includes the step of co-administering to the subject over three to five weeks, a taxane in an amount of between about 243 μmol/m2 to 315 μmol/m2 (e.g., equivalent to paclitaxel in about 210-270 mg/m2); and a bis(thiohydrazide amide) in an amount between about 1473 μmol/m2 and about 1722 μmol/m2 (e.g., Compound (1) in about 590-690 mg/m2). The bis(thiohydrazide amide) is represented by Structural Formula (I), Y is a covalent bond or an optionally substituted straight chained hydrocarbyl group, or, Y, taken together with both >C=Z groups to which it is bonded, is an optionally substituted aromatic group.
