Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients must have radiographic findings consistent with either:
  • Recurrent high-grade glioma, or
  • Metastatic disease to the brain that has progressed after treatment with whole brain radiation therapy or stereotactic radiosurgery; patients who have a resectable brain metastasis as the only site of disease (i.e., no evidence of systemic disease), are not eligible to participate
  • Patients who are in need of a surgical debulking or a stereotactic biopsy for the purpose of diagnosis or differentiating between tumor progression versus treatment-induced effects following radiation therapy +/- chemotherapy will be eligible to participate in the microdialysis part of the study prior to beginning cycle 1 of bafetinib if the study neurosurgeon thinks there is a likelihood of being able to place the microdialysis catheter into residual tumor (enhancing brain tissue)
  • Patients who choose not to participate in the microdialysis part of the study may enroll in the study and start treatment at cycle 1 of bafetinib
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for 3 months following duration of study participation; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately

  • All subjects must have the ability to understand and the willingness to sign a written informed consent
  • Patients must have recovered from any toxicity of prior therapies (including brain radiation); an interval of at least 6 weeks must have elapsed since the completion of a nitrosourea-containing chemotherapy regimen; patients who have undergone a recent craniotomy cannot begin bafetinib until at least 2 weeks after the surgery

Who cannot join

  • Patients who have a serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol or may not be able to comply with the safety monitoring requirements of the study
  • Human immunodeficiency virus (HIV)-positive patients receiving anti-retroviral therapy are excluded from the study due to the possibility of pharmacokinetic (PK) interactions with bafetinib; however, patients will not be routinely screened for HIV

About this study

Official title: BAFETINIB-P1-GBM-01: A Pilot Study Using Intracerebral Microdialysis to Determine the Neuropharmacokinetics of Bafetinib in Patients With Recurrent Brain Tumors

RATIONALE: Bafetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This clinical trial studies bafetinib in treating patients with recurrent high-grade glioma or brain metastases.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the neuropharmacokinetics (nPK) and systemic levels of bafetinib in patients with recurrent malignant brain tumors.

SECONDARY OBJECTIVES:

  1. To investigate the intrapatient variability of nPK parameters as assessed by intracerebral microdialysis.

II. To document the toxicity of bafetinib in this cohort of patients. III. To describe the response rate, progression-free survival, and overall survival in patients with malignant brain tumors treated with bafetinib.

IV. To assess for the expression of Lyn and Fyn kinases and phosphorylation status in pre-treatment tumor samples.

OUTLINE:Patients undergo intracerebral microdialysis during debulking craniotomy or stereotactic biopsy. Beginning 24 hours later, patients receive oral bafetinib twice daily for 1 day. Beginning at least 2 weeks after craniotomy or 1 week after biopsy, patients continue to receive oral bafetinib twice daily in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days and then every 8 weeks thereafter.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing bafetinib, microdialysis and pharmacological study in people with Adult Anaplastic Astrocytoma and Adult Anaplastic Ependymoma, run by City of Hope Medical Center 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?

The sponsor lists 18 inclusion and 12 exclusion criteria. 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 17 Apr 2018. 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?

Area-under-the-concentration-time-curve (AUC) of bafetinib in dialysate (time frame: every hour for 24 hours after first dose of bafetinib). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01234740, which also lists 1 linked publication.

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 17 Apr 2018; AzTrials last refreshed its copy on 8 Nov 2026.
