Trial summary

This clinical trial is being done to learn more about how different types of cancer treatments affect cancer cells when they spread to the brain. Many cancer treatments are not able to make their way into the brain or into spinal fluid of the central nervous system. Read more about this study

About this study

Official title: CSF Pharmacokinetics of Systemic Anti-Cancer Therapies in Patients With Advanced Cancer

This clinical trial is being done to learn more about how different types of cancer treatments affect cancer cells when they spread to the brain. Many cancer treatments are not able to make their way into the brain or into spinal fluid of the central nervous system. This is because they cannot cross what is called the "blood-brain barrier" or "BBB". The BBB is like a protective shield that only allows certain materials pass through to reach the brain but not others. This study is being initiated to help researchers learn more about what types of cancer treatments make it through the BBB to attack cancer cells within the brain, and what treatments do not make it through the BBB. Learning more about this may help future researchers develop more effective cancer drugs that better fight cancer cells that have spread to the brain.

Read the detailed description

Very little is known about the penetration of systemic therapies through the normal blood brain barrier and the ways in which a brain metastasis or radiation would impact the permeability of the blood brain barrier. This study would be one of the first to examine the concentrations of systemic cancer therapies in the cerebrospinal fluid (CSF) with matched serum samples. Additionally, the concentration of these therapies in brain metastasis surgical specimens would be of particular interest to correlate with serum and CSF levels, length of time on therapy, and latency to developing brain metastases in future studies.

As participants in this study, patients scheduled for a lumbar puncture per their standard of care treatment will be subject to a withdrawal of 15cc's of cerebrospinal fluid for pharmacokinetic analysis. They will also have a blood draw of 5mL within 2 hours of the lumbar puncture for serum pharmacokinetics. If the patient is eligible for and elects to proceed with surgical resection of a brain metastasis, optional CSF and serum samples would be drawn at the time of resection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The concentration of drug metabolites of systemic anti-cancer therapies in the cerebrospinal fluid

    CSF pharmacokinetics of systemic anti-cancer therapies, as measured by the concentration of their metabolites in the cerebrospinal fluid, will be obtained via lumbar puncture. The lumbar puncture will take place within 2 half-lives of the last dose of systemic therapy. Because a wide variety of anti-cancer therapies will be studied in this trial, there is significant variability in the half-lives of these therapies. Some will take place 2-24 hours after the last dose of systemic therapy. Some will take place 1-6 days after the last dose of systemic therapy. Some will take place 1-3 weeks after the last dose of systemic therapy. The time of the lumbar puncture procedure will depend greatly on the identity of the systemic therapy with which the subject is being treated. In patients undergoing surgical resection of a brain metastasis, an additional CSF sample is optional.

    Measured: up to 3 weeks

  2. Ratio of serum to CSF concentration of systemic anti-cancer therapies as measured by concentration of drug metabolites in serum and in CSF

    CSF and serum pharmacokinetics of systemic anti-cancer therapies, as measured by the concentration of their metabolites, will be obtained via lumbar puncture and blood draw, respectively. The lumbar puncture and blood draw will take place together within 2 half-lives of the last dose of systemic therapy. Because a wide variety of anti-cancer therapies will be studied in this trial, there is significant variability in the half-lives of these therapies. Some will take place 2-24 hours after the last dose of systemic therapy. Some will take place 1-6 days after the last dose. Some will take place 1-3 weeks after the last dose. The time of the lumbar puncture procedure will depend greatly on the identity of the systemic therapy with which the subject is being treated. In patients undergoing surgical resection of a brain metastasis, an additional matched CSF and serum sample is optional.

    Measured: up to 3 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Metastatic Cancer Patients on an Anti-cancer Therapy and Advanced Cancer, run by Duke University at 1 site 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 11 inclusion and 2 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: stopped early, as of the sponsor's last update on 28 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

Are results available for this study?

The study was stopped early (reason given: Inadequate Accrual). Results are not available in the source record.

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?

The concentration of drug metabolites of systemic anti-cancer therapies in the cerebrospinal fluid (time frame: up to 3 weeks). The study lists 2 primary outcomes in all. 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 28 Feb 2018.
