Brief summary

The purpose of this study is to explore a treatment that potentially enhances the delivery of chemotherapy to tumors in participants with superficial bladder cancer. The investigational medication to be studied is an enzyme called ChemophaseTM (recombinant human hyaluronidase, rHuPH20). Chemophase is being specifically developed for use with other anticancer drug to increase the local penetration of the anticancer drug for the treatment of superficial bladder cancer. In this study, Chemophase will be given in combination with mitomycin C directly into the bladder. Mitomycin C is an anti-tumor drug that is commonly used to treat superficial bladder cancer. It is envisioned that Chemophase with mitomycin C may potentially increase the local penetration of mitomycin C into remaining cancer cells following surgery to treat superficial bladder cancer.

Detailed description

The primary objectives of this study are to: 1. determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of escalating doses of Chemophase in combination with mitomycin (mitomycin C, MMC) administered as weekly intravesical instillations for five weeks, and 2. establish the dose of Chemophase with MMC recommended for future studies. The secondary objectives of this study are to: 1. assess the pharmacokinetics of intravesical administration of MMC alone and in combination with intravesical administration of Chemophase, 2. for those participants treated at the MTD, assess the safety and tolerability of intravesical administration of MMC with Chemophase over up to 7 additional maintenance treatments every 3 months following the initial six weekly instillations, and 3. observe participants for any preliminary evidence of anti-tumor activity of MMC and Chemophase when combined. Study participants will receive six weekly study treatments administered intravesically (at Weeks 1 through 6) followed by post-treatment evaluations, at Weeks 8 and 12. The 12 participants treated at MTD will continue to receive combination therapy every three months until the end of Year 2 or until the time of documented tumor recurrence, whichever occurs first. For other participants, long-term follow-up after Week 12 will consist of disease monitoring of participants by telephone and will be performed every three months beginning three months after last study treatment for two years and then every six months thereafter, until bladder tumor recurrence.
