Bladder Cancer Clinical Trial
Official title:
A Phase 1-2a, Multicenter, Open-Label, Multiple Dose, Safety, Tolerability, and Pharmacokinetic Study of Recombinant Human Hyaluronidase (Chemophase®) in Combination With Mitomycin in Patients With Non-Muscular-Invasive Bladder Cancer

Study type | Interventional |
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.

Primary | Maximum Tolerated Dose (MTD) of Chemophase in Combination With MMC | The MTD was defined as the maximum dose level at which no more than two of six participants experienced dose-limiting toxicities (DLT). DLT was defined as any of the following: Plasma MMC concentration greater than or equal to (>=) 100 nanograms (ng)/milliliter (mL) Adverse event (AE) with a Common Toxicity Criteria (CTC) grade greater than or equal to 3 New, treatment-emergent diagnosis of bladder fibrosis. |
5 weeks (Week 2 to Week 6) | |
Primary | Number of Participants With Dose Limiting Toxicities (DLTs) | DLT was defined as any of the following: Plasma MMC concentration >= 100 ng/mL AE with a CTC grade greater than or equal to 3 New, treatment-emergent diagnosis of bladder fibrosis. |
5 weeks (Week 2 to Week 6) | |
Primary | Recommended Dose of Chemophase With MMC For Future Studies | 5 weeks (Week 2 to Week 6) | ||
Secondary | Number of Participants With a Quantifiable MMC Plasma Concentration Value | A quantifiable MMC plasma concentration value was a value that was not below the quantifiable limit (BQL) of <10.0 nanogram/milliliter (ng/mL). | 0 (predose), 1, 2, and 3 hours postdose at Weeks 1, 2, 5, and 6 | |
Secondary | Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) | TEAEs were defined as any AE that occurred after the first administration of the study drug and until the end of the study. AEs were defined as any untoward medical occurrence in a participant administered study drug and that did not necessarily have a causal relationship with the study drug. SAEs were defined as any AE that, in the view of either the Investigator or Sponsor, resulted in any of the following outcomes as fatal, life-threatening, required in-participant hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, an important medical event. A summary of all SAEs and Other AEs (nonserious) regardless of causality is located in 'Reported Adverse Events' Section. | Baseline up to 2 years | |
Secondary | Number of Participants Who Remained Tumor Free at the End of the Study | Baseline up to 2 years |
