About this study

Official title: Efficacy and Safety Study of Rituximab, Methotrexate and Lenalidomide Chemotherapy（R2-MTX） in Newly Diagnosed Primary Central Nervous System Lymphoma：a Single Arm, Multicenter, Phase 2 Study

It is a single arm, multicenter, phase 2 study to explore the efficacy and safety study of R2-MTX chemotherapy（Lenalidomide, Rituximab and Methotrexate）as first-line regimens in the treatment of newly diagnosed primary central nervous system lymphoma. Objective response rate is the primary endpoint.

Read the detailed description

This is a single arm, multicenter, phase 2 study designed to evaluate the efficacy and safety of rituximab, methotrexate and lenalidomide as first-line regimens in the treatment of newly primary central nervous system lymphoma. A total of 40 patients plan to participate in this study to receive a total 6 cycles of induction chemotherapy followed by 4 cycles of maintenance chemotherapy. Follow-ups should be taken up to the first 3 years. The primary endpoint is objective response rate (ORR) and secondary endpoint includes Progression free survival (PFS), overall survival (OS), and adverse events.

What participants receive

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

  • RituximabDrug

    375mg/m2 intravenous infusion d1, every 3 weeks for 1 cycle, 6 cycles will be prescribed for induction therapy. 375mg/m2 intravenous infusion d1, every 8 weeks for 1 cycle, 4 cycles will be prescribed for maintenance therapy.

  • LenalidomideDrug

    25mg orally d1-10 every 3 weeks for 1 cycle, 6 cycles will be prescribed for induction therapy. 25mg orally d1-14,d29-42 every 8 weeks for 1 cycle, 4 cycles will be prescribed for maintenance therapy.

  • MethotrexateDrug

    3.5g/m2 intravenous infusion for 4 hours in d1, every 21 days for 1 cycle, 6 cycles will be prescribed.

What is being measured

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

  1. Objective response rate(ORR)

    The objective response rate is defined as the proportion of patients with a response of complete response(CR) or partial response(PR).

    Measured: At the end of Cycle 6 chemotherapy (each cycle is 21 days), assessed up to 18 weeks.

Secondary outcomes (3)

  1. Progression free survival

    From date of patients sign informed consent until the date of progression or death or the date of last follow-up time, whichever came first, assessed up to 3 years

    Measured: 3 years

  2. Overall survival

    From date of patients sign informed consent until the date of death or the date of last follow-up time, whichever came first, assessed up to 3 years

    Measured: 3 years

  3. Treatment-related adverse events

    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Rituximab, Lenalidomide and Methotrexate in people with Primary Central Nervous System Lymphoma, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

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 13 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 23 Nov 2022. 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 China. 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 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?

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?

Objective response rate(ORR) (time frame: At the end of Cycle 6 chemotherapy (each cycle is 21 days), assessed up to 18 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 NCT04934579, 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 23 Nov 2022.
