Safety Study of Recombinant Human Hyaluronidase (Chemophase) in Combination With Mitomycin in Participants With Superficial Bladder Cancer

Completed · Phase 1/Phase 2

Conditions studied: Bladder Cancer

In brief

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.

• Urinalysis showing no clinically significant abnormalities except those attributable to bladder cancer.
• For men and women of child-producing potential, agreement to use an effective contraceptive method during the treatment period of the study.
• Signed, written Institutional Review Board (IRB)-approved informed consent

You may not qualify if…

• History or previous diagnosis of bladder fibrosis
• Total bladder capacity estimated at cystoscopy to be less than 150 mL
• Urinary incontinence of a severity that would compromise the ability of the participant to retain the study drug intravesical instillation for two hours.
• Severe irritative voiding symptoms such as urgency, frequency, or nocturia
• Known other malignant disease except squamous or basal cell skin cancer unless the malignancy has been in complete remission off therapy for at least 5 years.
• Major surgery, other than TURBT and diagnostic surgery, within 28 days prior to Day 1/Week 1.
• Active, uncontrolled bacterial, viral, or fungal infections, including urinary tract infection.
• Treatment with radiation therapy, surgery, chemotherapy, or investigational therapy within one month prior to Day 1/Week 1 on study (two months for nitrosureas or MMC), unless given as standard treatment for bladder cancer and provided that patient is free of all treatment-related toxicities as of Day 1/Week 1.
• Known infection with human immunodeficiency virus (HIV)
• Known active infection with hepatitis B or hepatitis C
• Serious disease (e.g., hydronephrosis, liver failure, or other conditions) that could compromise protocol objectives in the opinion of the Investigator and/or the Sponsor (Halozyme).
• History of a hypersensitivity or idiosyncratic reaction to, or other contraindication to, mitomycin.
• Known allergy to bee or vespid venom
• Known coagulation disorder or bleeding tendency
• Treatment with heparin or anticipation of heparin treatment during the treatment period in this study.
