Bone Marrow SuppressionPhase 1NCT00005796
Combination Chemotherapy Plus Gene Therapy in Treating Patients With CNS Tumors
A Phase 1 study testing filgrastim, gene therapy and lomustine in people with Bone Marrow Suppression and Brain and Central Nervous System Tumors, run by Indiana University at 2 sites in United States.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Inserting a specific gene into a person's peripheral stem cells may improve the body's ability to fight cancer or make the cancer more… Read more about this study

About this study
Official title: A Pilot Study of Dose-Intensified Procarbazine, CCNU, Vincristine (PCV) for Poor Prognosis Pediatric and Adult Brain Tumors Utilizing Fibronectin-Assisted, Retroviral-Mediated Modification of CD34+ Peripheral Blood Cells With O6-Methylguanine DNA Methyltransferase
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. Inserting a specific gene into a person's peripheral stem cells may improve the body's ability to fight cancer or make the cancer more sensitive to chemotherapy.
PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy plus gene therapy in treating patients who have CNS tumors.
Read the detailed description
OBJECTIVES: I. Determine the toxicity (detection of replication competent retrovirus) associated with CD34+ cells transduced with a retroviral vector expressing human O6-methylguanine DNA methyltransferase in adult and pediatric patients with poor prognosis CNS tumors. II. Determine the safety of genetic modification of cells carried out in the presence (ex vivo) of recombinant fibronectin (FN) fragment utilized to assist in retroviral entry into mammalian cells. III. Determine any evidence of engraftment of cells exposed to FN during retroviral transduction. IV. Determine any evidence of antibodies to FN following infusion of cells exposed to FN during ex vivo retroviral transduction.
OUTLINE: Patients with surgically approachable lesions undergo maximal surgical debulking that allows preservation of good neurologic functioning. Harvest: Patients receive filgrastim (G-CSF) subcutaneously or IV beginning 4 days prior to initiation of first leukapheresis and continuing until completion of harvest. Peripheral blood stem cells are harvested and selected for CD34+ cells which are transduced with a fibronectin assisted retroviral vector expressing human O6-methylguanine DNA methyltransferase. Intensification: Patients receive oral lomustine and vincristine IV on day 0 and oral procarbazine on days 1-7. Treatment repeats every 4 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with newly diagnosed tumors may undergo involved field radiotherapy (IF-RT) after completion of the third course of chemotherapy and may begin the fourth course of chemotherapy after completion of IF-RT. Transplantation: Two-thirds of the transduced CD34+ cells are reinfused on day 9 of the first course of chemotherapy. The remaining portion (one-third) of the transduced CD34+ cells are reinfused on day 9 of the second course of chemotherapy. Untransduced CD34+ cells are reinfused on day 9 of the last 3 courses of chemotherapy. Patients are followed every 3 months for 6 months, every 4 months for 1 year, every 6 months through year 5, and then annually thereafter.
PROJECTED ACCRUAL: Approximately 15-20 patients will be accrued for this study within 1 year.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing filgrastim, gene therapy and lomustine in people with Bone Marrow Suppression and Brain and Central Nervous System Tumors, run by Indiana University at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Determine the toxicity (detection of replication competent retrovirus) associated with CD34+ cells transduced with a retroviral vector expressing human O6-methylguanine DNA methyltransferase in adult and pediatric patients with poor prognosis CNS tumors. (time frame: Year 2). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2015.
