3Topotecan is a FDA-approved drug when given by intravenous injection, but it is not effective against brain tumors when given intravenously. The Cleveland Multiport Catheter is a new, investigational device that will be used to deliver topotecan directly into participants' brain tumors. One purpose of this study is to determine whether the Cleveland Multiport Catheter can be used effectively and safely to deliver topotecan directly into brain tumors. This study will also evaluate different doses of topotecan that can be delivered to a participant's brain tumor with use of the Cleveland Multiport Catheter, and it will also examine how their tumor responds to treatment with topotecan.
This study will look at the way topotecan is injected into participant's tumor. A small amount of contrast dye (called gadolinium DTPA) will be added to topotecan before it is injected. Pictures will be taken of the tumor with an MRI machine. This will allow the investigators to see where in the tumor the topotecan has been injected. Issues related to patient selection, coordination with other therapeutic and palliative clinical options, and patient quality of life impact will be studied. Except for the infusion of topotecan and gadolinium DTPA into the tumor, and MRI imaging of the infusion process, all procedures and treatments participants will experience during the care of their brain tumor are non-investigational; the types of medical treatments, procedures, and tests they experience will be Standard of Care for patients with brain tumors.
Primary Objectives:
To investigate by MR imaging the spatial and temporal distribution of topotecan in tumor and tumor-infiltrated brain administered by convection-enhanced delivery (CED) in patients with recurrent/progressive WHO grade III or IV (high grade) glioma (HGG) who have failed standard therapy comprising surgical biopsy and/or resection and adjuvant chemotherapy and radiotherapy
To investigate by MR imaging the influence of the rate and topotecan concentration, on the spatial and temporal distribution of topotecan administered by CED in patients with recurrent/progressive HGG
To evaluate the spatial and temporal distribution of topotecan, by MR imaging, when delivered into enhancing tumor tissue versus non-enhancing tumor tissue (as defined on pre-operative conventional MRI imaging with and without intravenous gadolinium)
Secondary Objectives:
To investigate the extent to which backflow may be observed on MRI during CED-mediated delivery of topotecan
To assess the safety, tolerability and toxicity profile of topotecan administered by CED using different doses and infusion rates
To observe evidence of activity of single-agent topotecan administered by CED to patients with recurrent/progressive HGG who have failed standard therapy comprising surgical biopsy and/or resection and adjuvant chemotherapy and radiotherapy
Topotecan is a chemotherapy that is approved by the FDA to treat cancers. It is normally given by an intravenous injection, and not directly into a tumor. That is why it is considered to be an investigational drug for this study
Gadolinium DTPA is a contrast agent which will be added to topotecan to allow the investigators to observe where topotecan goes in tumors. Gadolinium DTPA is approved by the FDA for intravenous injection during an MRI scan. It is not approved by the FDA for administration directly into a tumor.
The Cleveland Multiport Catheter is a device that is not approved by the FDA and so it is classified as an investigational device. It has been designed to deliver drugs and other agents intended to treat cancers directly into the affected tissues. The Cleveland Multiport Catheter can be placed into a brain tumor only in the operating room. It is placed during an operation to perform a biopsy of brain tumors. Following the biopsy, a surgeon will place two catheters into the tumor with use of an image guided navigation system. Once each catheter has been placed, it will be secured into the scalp and the incision will be closed. The Cleveland Multiport Catheter will be left in place until the completion of the topotecan treatment.
The experimental Cleveland Multiport Catheter will be used to inject a chemotherapy, topotecan, and a contrast agent, gadolinium DTPA, into the high grade brain tumors of study participants
