简要总结
Background:
- Urothelial cancer (tumors of the bladder, urethra, ureter, or renal pelvis) often responds initially to standard chemotherapy treatments, but frequently recurs and can often spread to other parts of the body. TRC105, an experimental drug that blocks the development of the new blood vessels needed for tumor growth, may be able to shrink or stabilize urothelial cancer tumors. TRC105 has been given previously to individuals with other types of cancer, and researchers are interested in determining its safety and effectiveness in treating urothelial cancer.
Objectives:
- To determine the safety and effectiveness of TRC105 as a treatment for metastatic urothelial cancer that has not responded to standard treatments.
Eligibility:
- Individuals at least 18 years of age who have been diagnosed with urothelial cancer that has spread to other parts of the body and has not responded to standard chemotherapy.
Design:
- Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies.
- Participants will receive TRC105 intravenously once every 2 weeks on days 1 and 15 of a 28-day treatment cycle. The first dose of TRC105 will be given over a 4-hour period; participants who do not have side effects may receive the next dose over 2 hours. If the second dose is tolerated, subsequent doses can be given over at least 1 hour.
- To help prevent known side effects of TRC105, participants will take two doses (one in the morning and one in the evening) of the steroid dexamethasone on the day before each infusion is scheduled. Participants may have additional dexamethasone 30 minutes before infusion, and may have the infusion slowed or stopped to adjust for side effects.
- Participants will be monitored with blood samples, physical examinations, and tumor imaging studies through the cycles of treatment.
- Participants will continue to take TRC105 for as long as the treatment is effective against the cancer and as long as the side effects are not severe enough to stop treatment.
详细描述
BACKGROUND:
- In the United States, urothelial carcinoma (UC) of the bladder is the 4th most common malignancy in men and the 9th most common in women with an estimated 70,980 new cases and 14,330 deaths in the year 2009. Although it is chemosensitive with response proportions of over 50% with conventional cytotoxic regimens, the response durations are short and the median survival of patients with metastatic disease is approximately 14 months.
- TRC105 is a genetically engineered human/murine chimeric monoclonal antibody that inhibits angiogenesis and tumor growth via endothelial cell growth inhibition and apoptosis. TRC105 is directed against human CD105 (endoglin), an angiogenic membrane protein that is highly expressed on proliferating vasculature in solid tumors and up-regulated following anti-VEGF (vascular endothelial growth factor) therapy. Clinical studies in bladder cancer with anti-angiogenic agents have shown anti-tumor activity.
- TRC105 targets a unique mechanism for tumor angiogenesis, through modification of CD105 signaling. In patients with advanced bladder cancer that have progressed through standard chemotherapy and have no further life prolonging therapeutic options, use of this novel angiogenesis inhibitor may improve outcomes.
OBJECTIVES:
- To measure PFS (progression free survival) of TRC105 as determined by RECIST (Response Evaluation Criteria in Solid Tumors) v1.1
- To determine the safety and toxicity of TRC105 in this patient population.
- In addition, in a preliminary fashion, response rate and overall survival of patients with metastatic urothelial carcinoma of the bladder treated with TRC105 will be estimated.

结局指标
主要结局
Progression Free Survival
时间窗: after 6 months on study
Time interval from start of treatment to documented evidence of disease progression. Progressive disease is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm (Note: the appearance of one or more new lesions is also considered progression).-
次要结局
- Number of Participants With Adverse Events(24 months)
- Objective Response(up to 25 months)
- Median Overall Survival(up to 25 months)
- Incidence of TRC-105-Related Adverse Events(24 months)
