Safety Study of Intracerebral Topotecan for Recurrent Brain Tumors
This trial is active, not recruiting.
|Condition||brain neoplasms, primary malignant|
|Treatments||convection-enhanced delivery, topotecan|
|Phase||phase 1/phase 2|
|Sponsor||Jeffrey N. Bruce|
|Start date||March 2004|
|End date||September 2011|
|Trial size||18 participants|
|Trial identifier||NCT00308165, AAAA4229, R01CA089395|
This study will evaluate the safety and efficacy of a chemotherapeutic drug (topotecan) as it is given directly into brain tumors by a delivery technique called convection-enhanced delivery. This drug has been used for different types of cancer, but in this study it will be given by an experimental delivery technique designed to maximize the amount of drug delivered to the brain tumor and minimize the side effects in other parts of the body.
This study will also evaluate advanced magnetic resonance (MR) imaging techniques.
The study will assess quality of life parameters throughout the follow-up period.

|Official title||A Phase I Study of Topotecan by Intracerebral Clysis for the Treatment of Recurrent Primary Malignant Brain Tumors|
|Principal investigator||Jeffrey Bruce, MD|
|Description||Clinical efficacy with chemotherapy has been discouraging for malignant brain tumors, mostly because of side effects and delivery limitations. Because they are locally invasive and rarely metastasize, malignant gliomas have features that make them uniquely amenable to new strategies of regional drug delivery. Intracerebral clysis (convection-enhanced delivery) is a novel drug delivery strategy that uses a microinfusion pump to establish a pressure gradient in the brain via implanted catheters. The pressure gradient produces convective forces that distribute a therapeutic agent throughout the tumor and surrounding brain tissue. Non-invasive magnetic resonance imaging (MRI) methods of monitoring drug distribution and treatment response have been developed to maximize the clinical applications and minimize complications associated with treatment risks. Study participants will be taken to the operating room to have 2 catheters surgically placed into their tumor and surrounding tumor bed. These catheters will then be connected to small infusion pumps which will slowly infuse topotecan continuously over 4-5 days. Patients will have daily MRI scans while in the hospital. Upon completion of the experimental treatment, patients will be discharged and will be followed up in the outpatient clinic.|
