This phase I trial tests the safety, tolerability and effectiveness of PLZ4-coated paclitacel-loaded micelles (PPM) in treating patients with non-muscle invasive bladder cancer that has come back after a period of improvement (recurrent) or that does not respond to treatment (refractory). PPM is a bladder cancer-specific nanoparticle that can specifically target and deliver treatment to the tumor cells in the bladder. PPM contains paclitaxel, which is a drug that kills tumor cells or keeps them from growing.
Histologically confirmed non muscle invasive bladder cancer (NMIBC), defined as noninvasive papillary carcinoma (Ta), carcinoma in situ (CIS) or carcinoma invading the subepithelial connective tissue (T1), determined via transurethral resection of bladder tumor (TURBT) within 3 months of enrollment
Persistent or recurrent CIS alone or with recurrent Ta/T1 (noninvasive papillary disease/tumor invades the subepithelial connective tissue) disease within 12 months of completion of adequate BCG therapy
Recurrent high-grade Ta/T1 disease within 12 months of completion of adequate BCG therapy
At least five of six doses of an initial induction course plus at least two of three doses of maintenance therapy
Existence of cancer at the upper urinary tract
Concurrent use of other investigational agents
Evidence of regional and/or distant metastasis
NYHA (New York Heart Association) class III or IV heart failure, uncontrollable supraventricular arrhythmias, any history of a ventricular arrhythmia, or other clinical signs of severe cardiac dysfunction
