Bortezomib With Gemcitabine/Doxorubicin in Patients With Urothelial Cancer and Other Solid Tumors
The goal of this clinical research study is to find the highest tolerable dose of Gemzar® (gemcitabine) and Adriamycin® (doxorubicin) that can be given together with Velcade® (bortezomib) in patients with urothelial cancer or other solid tumors.

Gemcitabine and doxorubicin are designed to disrupt the growth of cancer cells, which causes cancer cells to start to die. Bortezomib is designed to enter cells and interfere with a substance found inside cells that is responsible for allowing cells to divide. This helps to kill the tumor cells.
If you are found to be eligible to take part in this study, you will receive doses of the study drugs based on when you join the study and how many people have started before you. Two (2) participants will be entered into each dose level. Additional participants may be added at a dose level if it is being well tolerated. The doses will increase until the highest tolerable dose is found.
You will receive the 3 study drugs on the first day of each cycle. You will receive gemcitabine for up to 90 minutes. Next you will receive doxorubicin over 15-30 minutes. Bortezomib will be given last over 3-5 seconds. Every 14 days is considered a study "cycle."
While on study, you will have a complete physical exam before each dose of study drugs. Blood (about 3 teaspoons) will be drawn to check bone marrow and kidney function each week during the first month. The study doctor may decide to draw blood more often, if you are having side effects to the study drugs. Your vital signs will be measured before you receive the study drugs and 1 hour after the infusion.
At the end of Cycle 3, your tumor status will be re-evaluated. You will have CT scans and a bone scan. Blood (about 2 tablespoons) will be drawn for routine tests.
You will be taken off study if the disease gets worse or intolerable side effects occur. If you have stable disease, you may continue receiving therapy as long as your physician feel you are benefiting.
Once you are off-study, you will receive a phone call every 6 months. You will be asked how you are doing, the status of the disease, and if you have had other treatments.
This is an investigational study. Gemcitabine, doxorubicin, and bortezomib are all FDA approved and commercially available. Their use in this study is considered investigational because they have not been approved in patients with urothelial cancer. Up to 80 patients will take part in this study. All will be enrolled at MD Anderson.
