Additional Study Information: This research study will investigate an experimental, unapproved drug that will be given two different ways; as an injection in the bladder wall after bladder tumor resection surgery (or TURBT) and then as an intravesical instillation (fluid inserted in the bladder by catheter) right after the injection. The purpose of this study is to find the dose which is tolerated the best, gives the least side effects when injected directly into the resected bladder and instilled in the bladder, and to find out which dose may kill cancer cells.
