RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine hydrochloride and cisplatin together with temsirolimus may kill more tumor cells.
PURPOSE: This phase I/II trial is studying the side effects and best dose of temsirolimus given together with gemcitabine hydrochloride and cisplatin as first-line therapy in treating patients with locally advanced and/or metastatic transitional cell cancer of the urothelium.
- To determine a safety profile of temsirolimus in combination with cisplatin and gemcitabine hydrochloride, including dose-limiting toxicities (DLTs) and maximum-tolerated dose (MTD) in patients with locally advanced and/or metastatic transitional cell carcinoma of the urothelium. (phase I)
- To determine the recommended dose for the Phase II stage of the trial and subsequent studies. (phase I)
- To assess progression-free survival (PFS) at six months from date of enrollment. (phase II)
- To determine the pharmacokinetic profile of temsirolimus in combination with cisplatin and gemcitabine hydrochloride. (phase I)
- To determine tolerability (side-effects) and feasibility (number of participants requiring dose delays or reduction and/or treatment withdrawal). (phase II)
- To determine objective response rate as assessed by RECIST. (phase II)
- To assess PFS of these patients. (phase II)
- To assess overall survival of these patients. (phase II)
- To determine toxicity during and after treatment in these patients. (phase II)
OUTLINE: This is a multicenter, phase I dose-escalation study of temsirolimus followed by a phase II study.
Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, cisplatin IV over 3-4 hours on day 1, and temsirolimus IV over 30 minutes on days 1 or 2, 8 or 9, and 15. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Blood specimens may be collected periodically for pharmacokinetic studies.
After completion of study treatment, patients are followed at 6 months and 1 year.

Collecting duct carcinoma (CDC) is a rare type of renal cancer with a poor prognosis. As there are no standard guidelines for the management of metastatic CDC (mCDC), we evaluated the efficacy and saf...
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
Tumors or cancer of the URINARY BLADDER.
A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.
Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.
An abnormal passage in the URINARY BLADDER or between the bladder and any surrounding organ.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
