About this study

Official title: Safety and Efficacy of Intrathecal Rituximab in Patients With Lymphoid Malignancies Involving the Central Nervous System

The goal of this clinical research study is to learn about the safety and effectiveness of rituximab given by spinal tap in patients with lymphoid malignancies involving the central nervous system.

A spinal tap (also called a lumbar puncture) is when fluid surrounding the spinal cord is collected by inserting a needle into the lower back. The affected area is numbed with local anesthetic during the procedure. It will also be used to give chemotherapy in this study.

Rituximab is designed to bind to a protein, called CD20, that is on the surface of the leukemia cells. This may cause the leukemia cells to die.

Read the detailed description

Study Groups and Study Drug Administration:

If you are found to be eligible, you will be assigned to a study group based on when you join this study. Up to 12 participants will be enrolled in the Phase I portion of the study, and up to 13 participants will be enrolled in Phase II.

If you are enrolled in the Phase I portion, the dose of rituximab you receive will depend on when you joined this study. The first group of participants will receive the lowest dose level of rituximab. Each new group will receive a higher dose of rituximab than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of rituximab is found.

If you are enrolled in the Phase II portion, you will receive rituximab at the highest dose that was tolerated in the Phase I portion.

Study Visits:

Once enrolled, you will return to the clinic and receive the study drug by spinal tap up to 2 times a week. You will receive treatment twice a week until 2 CSF samples in a row do not show any leukemia cells. After that, you will receive treatment 1 time a week for an additional 4 weeks, and then you will receive treatment once every other week for an additional 8 weeks. The number of doses you receive will depend on how many doses the study doctor thinks is needed.

At each study visit the following procedures will be performed:

  • You will have a physical exam, including measurement of your weight, and vital signs. °Your vital signs will be measured every 15 minutes for 1 hour after each dose of rituximab.
  • You will be asked how well you are able to perform the normal activities of daily living (performance status).
  • You will be asked about any drugs you may be taking and any side effects you may experiencing.
  • Blood (about 2 tablespoons) will be drawn for routine tests.
  • A sample of cerebral spinal fluid may be collected from the lumbar puncture to verify the absence or presence of blast cells.

Follow-Up:

About 30 days after your last dose of study drug you will be contacted by the study staff by telephone and asked about any drugs you may be taking and any side effects you may experiencing. This call should take about 10 minutes.

Long-term Follow-up:

Every 6 to 12 months you may be contacted by the study staff by telephone and asked about any drugs you may be taking and any side effects you may experiencing. This call should take about 10 minutes.

You may be given other drugs to help prevent side effects. The study staff will tell you about these drugs, how they will be given, and the possible risks.

Length of Treatment:

The number of treatments you receive will depend on how long it takes for there to be no leukemia cells in the CSF samples. Once this happens, you will have treatments for an additional 12 weeks. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

This is an investigational study. Rituximab is FDA approved and commercially available for the treatment of relapsed and/or refractory lymphoid malignancies involving the central nervous system. Receiving rituximab by spinal tap is considered investigational.

Up to 25 patients will take part in this study. All will be enrolled at MD Anderson.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intrathecal RituximabDrug

    Also called Rituxan

    Phase I: Starting dose Rituximab 10 mg intrathecally twice weekly until 2 consecutive CSF samples are negative for the presence of blast cells. Thereafter, rituximab 10 mg intrathecally weekly for additional 4 weeks, followed by intrathecal rituximab 10 mg administered once every other week for an additional 8 weeks.

    Phase II Starting Dose of Rituximab: Maximum tolerated dose from Phase I.

What is being measured

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

  1. Response Rate

    The percentage of participants whose cancer shrinks or disappears after treatment where participants are considered as responding to therapy if the Cerebrospinal fluid (CSF) is without evidence of blast cells after four lumbar punctures with rituximab.

    Measured: 2 weeks

Secondary outcomes (1)
  1. Maximum Tolerated Dose (MTD) of Rituximab

    MTD is dose level at which at least 1 of 3 participants experiences a dose-limiting toxicity (DLT). DLTdefined as clinically significant adverse event or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications and meeting the NCI common terminology criteria that are CTCAE Grade 3 or 4.

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Intrathecal Rituximab in people with Leukemia and Lymphoid Malignancies, run by M.D. Anderson Cancer Center 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 7 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 24 May 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.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Mar 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Response Rate (time frame: 2 weeks). 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 24 May 2018.
