About this study
Official title: Phase I Study of Intraventricular Administration of Rituximab in Combination With Methotrexate in the Treatment of Recurrent CNS and Intraocular Lymphoma
Rituximab is the first monoclonal antibody to receive approval in the treatment of cancer and has been proven to lead to extended survival when administered intravenously in the treatment of patients with systemic non-Hodgkin's lymphoma. We have previously demonstrated that a small fraction of Rituximab administered intravenously is able to cross the blood-brain-barrier into the brain.
We will test the idea that the direct injection into the cerebrospinal fluid of Rituximab, a monoclonal antibody which attacks and kills lymphoma cells, is safe and when used in combination with methotrexate in patients with recurrent brain and intraocular lymphoma.
We will also test the idea that the combination of rituximab plus methotrexate has activity and is effective in the treatment of recurrent brain and intraocular lymphoma.
Read the detailed description
Rituximab is the first monoclonal antibody to receive FDA approval in the treatment of cancer. Intravenous administration of rituximab has been demonstrated to lead to prolongation of survival when used in combination with chemotherapy in the treatment of patients with systemic non-Hodgkin's lymphoma. We have previously demonstrated that a small fraction of Rituximab administered intravenously is able to cross the blood-brain-barrier into the brain and we have also previously demonstrated that direct intraventricular administration of Rituximab is able to achieve high concentrations within the cerebrospinal fluid ventricles and lumbar sac.
We will test the hypothesis that the direct intraventricular injection of Rituximab in combination with Methotrexate is safe and when used in combination in patients with recurrent brain and intraocular lymphoma. We will evaluate the safety of this combination by testing different dose levels of Rituximab. We will also measure the concentration of Rituximab in the intraocular compartments and cerebrospinal fluid at different time points after intraventricular administration to determine the pharmacokinetics of intrathecal Rituximab as well as the potential impact of Methotrexate on Rituximab distribution.
We will also test the hypothesis that the intraventricular administration of the combination of rituximab plus methotrexate has activity and is effective in the treatment of recurrent brain and intraocular lymphoma.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intraventricular Rituximab Plus MTXDrug
Also called MTX, amethopterin, Rituxan, MabThera
Intraventricular injection of rituximab into an Ommaya reservoir on day 1 of each week. Intraventricular rituximab plus methotrexate (MTX) on day 4 of each week.
First three patients at dose A : 25 mg rituximab on day 1, and MTX (12 mg) plus rituximab (10 mg) on day 4 each week.
If there are no dose limiting toxicities at Dose A in all of the first 3 patients or in 5 of the first 6 patients, the next 3 patients will receive dose level B: 25 mg rituximab on day 1, and combination MTX (12 mg) plus rituximab (25 mg) on day 4 of each week.
Oral leucovorin rescue 24 hours after each MTX administration. Maximum injections will be 16 over 9-weeks. Subjects who experience a partial response at week 10 will be given the option for extended dosing.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Intraventricular Rituximab Plus MTX in people with Central Nervous System Lymphoma and Intraocular Lymphoma, run by University of California, San Francisco at 4 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 7 inclusion and 3 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 16 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 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?
whether intra-CSF administration of rituximab in combination with MTX in patients with recurrent CNS and intraocular lymphoma is associated with neurotoxicity (time frame: 4 weeks). 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 NCT00221325, 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 16 Feb 2015; AzTrials last refreshed its copy on 7 Nov 2026.
