Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Convection-enhanced delivery (CED) is a method of regional drug delivery that circumvents this problem. Phase 1 clinical trial has shown that a potent topoisomerase inhibitor, topotecan (TPT), can be safely and effectively delivered by CED into patients with recurrent malignant gliomas. This study will expand on these clinical results to address two current limitations to the clinical application of CED: 1) A reliable method for non-invasively monitoring drug distribution throughout the tumor and brain does not exist; and 2) Duration of CED therapy has been limited to short-term infusions secondary to the use of externalized infusion pumps.
The hypothesis is that extended chronic local-regional delivery of TPT is safe, effective and feasible in patients with recurrent gliomas. TPT will be directly and chronically delivered into the tumor and surrounding brain by CED through subcutaneously implanted pumps while innovating a methodology for monitoring the drug distribution through non-invasive imaging. This strategy will overcome the limitations of chemotherapy as currently used in the treatment of gliomas, and may be applicable to other central nervous system (CNS) diseases currently limited by drug delivery barriers.

Study Groups

Long term CED of Topotecan
An additional 5 patients will be treated with TPT by CED maintained for 32 days. TPT infusions will be carried out for 32 days using Synchromed II infusion pumps with the same infusion parameters and experimental conditions used in the short term studies.
Topotecan
Topotecan is a chemotherapeutic agent that is a topoisomerase inhibitor. TPT is administered through an externalized catheter and external microinfusion pump.
Dose: 146 micrometers (uM)
Gadolinium
Gadolinium is a widely available MRI contrast agent that is used routinely in clinical practice via IV administration, especially for imaging of intracranial tumors.
Synchromed II infusion pumps
Implanted subcutaneously to facilitate chronic infusion.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients with tumors of the brain must have been previously treated with surgical resection, external beam radiation, and temozolomide chemotherapy.
* An magnetic resonance (MR) scan must be obtained within 30 days of enrollment and must demonstrate an enhancing mass without significant mass effect. Tumors must be less than 32 cc in total volume. The lesion must be stereotactically accessible.
* Patients must have demonstrated evidence of increasing contrast enhancement on MR or computed tomography (CT) imaging while on stable or increasing dose of steroid.
* Karnofsky performance score of greater than or equal to 60.
* Men and women of childbearing potential must practice birth control. Women of child bearing potential must have a urine pregnancy test within 7 days of study entry.
* Patients must possess the ability to give Informed Consent.
* Patients must be willing to and medically capable of undergoing the surgical operation.
* There is no upper age limit. Patients at extreme upper end of the age spectrum will not be automatically excluded, but will be carefully scrutinized to determine their suitability for this procedure.
* Patients must be at least 18 years old.
* Patients must have normal organ and marrow function as defined below:
* Leukocytes: ≥3,000/ cells per microliter of blood (mcL)
* Absolute neutrophil count: ≥1,500/mcL
* Platelets: ≥100,000/mcL
* Total bilirubin: within normal institutional limits
* aspartate aminotransferase (AST) (SGOT)/alanine aminotransferase (ALT) (SGPT): ≤2.5 × institutional upper limit of normal
* Creatinine: within normal institutional limits OR
* Creatinine clearance: ≥60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
Exclusion Criteria
* Patients with tumors involving the cerebellum or both cerebral hemispheres.
* Patients with an active infection requiring treatment or having an unexplained febrile illness.
* Patients who are known HIV, Hepatitis B or Hepatitis C positive. HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with topotecan. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
* Patients with systemic diseases which may be associated with unacceptable anesthetic/operative risk.
* Patients who have previously received systemic topotecan for their tumor
* Patients who are not able to receive an MRI scan.
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to topotecan, other topoisomerase inhibitors or gadolinium compounds.
