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 18 years or older with stage I-IV indolent B cell lymphoma, including MALT and follicular grade I/II. Patients with mantle cell lymphoma will also be included in this study, as mantle cell lymphoma is also radiosensitive, despite it not being an indolent B cell lymphoma. Patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) are ineligible.
  • Patients must have measurable disease within the orbit, either clinically and/or radiographically after biopsy confirmation of B cell lymphoma.
  • Bilateral ocular adnexal involvement is permitted, if biopsy confirms unilateral disease and there is high clinical suspicion for bilateral disease, biopsy of the contralateral ocular adnexa can be waived.
  • Female patients of childbearing potential must have a negative serum pregnancy test (βhCG) within 2 weeks of protocol entry.
  • Planned systemic therapy after orbital radiation therapy is permitted however the timing of systemic therapy will be recorded and patients will be stratified according to receipt of adjuvant systemic therapy.
  • Male patients must agree to use a barrier method of contraception or agree to abstain from heterosexual activity for the duration of the study.
  • Female patients must be willing to use two adequate barrier methods of contraception to prevent pregnancy or agree to abstain from heterosexual activity throughout the study or be post-menopausal (free from menses > two years or surgically sterilized).
  • Patients must have the ability to give informed consent.

Who cannot join

  • Patients treated with chemotherapy for lymphoma within 4 weeks of protocol enrollment (including Rituxan).
  • Patients with aggressive B cell lymphoma histology, including diffuse large B cell lymphoma (DLBCL) and grade 3 follicular lymphoma.
  • Patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).
  • Patients with a history of prior radiation to the orbit if re-treatment would exceed known orbital tolerance.
  • Patients with pre-existing retinopathy.
  • Patients who are pregnant.
  • Patients with active lupus or scleroderma are ineligible

About this study

Official title: Ultra Low Dose 4 Gy Orbital Radiation for Definitive Therapy of Indolent B Cell Lymphoma

This phase II trial studies how well ultra low dose orbital radiation therapy works in treating patients with stage I-IV low grade (indolent) B-cell lymphoma or mantle cell lymphoma involving the orbit of the eye (space enclosed by the borders of the eye socket). Orbital radiation therapy uses external beam radiation to destroy cancer cells. Using ultra low dose orbital radiation therapy may be effective in treating indolent B-cell lymphoma or mantle cell lymphoma involving the eye and may have fewer side effects.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the efficacy of ultra low dose 4 Gray (Gy) orbital radiation, measured as local orbital control (i.e. local control within the radiation field), in patients with limited and advanced stage low grade B lymphocyte (B cell) lymphoma and mantle cell lymphoma involving the ocular adnexa.

II. To evaluate the efficacy of ultra low dose 4 Gy orbital radiation, measured as complete response, in patients with limited and advanced stage low grade B cell lymphoma and mantle cell lymphoma involving the ocular adnexa.

III. To evaluate the acute and chronic toxicity of radiation to the orbit.

SECONDARY OBJECTIVE:

  1. To determine if dynamic contrast enhanced magnetic resonance imaging can predict response to ultra low dose radiation therapy.

OUTLINE:

Patients undergo low dose orbital external beam radiation therapy (EBRT) on 2 consecutive days. Patients experiencing stable or progressive disease after 12-16 weeks of EBRT undergo additional low dose orbital EBRT over 10 fractions. Patients experiencing partial response or minimal response 1 year after EBRT also undergo low dose orbital EBRT over 10 fractions.

After completion of study treatment, patients are followed up every 3-4 months for 6-8 months, every 6-12 months for up to 2 years, and then periodically thereafter.

What participants receive

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

  • External Beam Radiation TherapyRadiation

    Also called Definitive Radiation Therapy, EBRT, External Beam Radiotherapy, External Beam RT

    Undergo orbital EBRT

  • Orbital RadiationDrug

    Also called XRT

    Participants receive radiation to entire involved orbit for a total dose of 4 Gy in 2 fractions over two consecutive days with external beam radiotherapy. If there is stable disease or progressive disease, an additional 20 Gy administered to involved site. If there are two consecutive evaluations with no change in disease burden then an additional 20 Gy administered. At one year if there is persistent disease, an additional 20 Gy administered to involved site.

What is being measured

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

  1. Local orbital control (i.e. local control within the radiation field)

    Local orbital event will be estimated using the Kaplan-Meier method.

    Measured: Up to 2 years post-radiation

Secondary outcomes (5)

  1. Complete response rate

    Response rate will be estimated along with 95% confidence intervals.

    Measured: Up to 2 years

  2. Local regional control (i.e. local control within the ipsilateral orbit but outside of the radiation field)

    Measured: Up to 2 years post-radiation therapy

  3. Overall survival (OS)

    OS will be estimated using the Kaplan-Meier method.

    Measured: Up to 2 years

  4. Freedom from distant relapse rates

    Measured: Up to 2 years

  5. Incidence of acute and chronic ocular toxicities graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03

    Toxicity data will be summarized by frequency tables.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing External Beam Radiation Therapy and Orbital Radiation in people with Ann Arbor Stage I B-Cell Non-Hodgkin Lymphoma and Ann Arbor Stage I Grade 1 Follicular Lymphoma, 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 8 inclusion and 7 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: under way, not looking for participants, as of the sponsor's last update on 15 Jul 2026. 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 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?

This study is still under way. Results are not available in the source record yet.

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?

Local orbital control (i.e. local control within the radiation field) (time frame: Up to 2 years post-radiation). 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 NCT02494700, 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 15 Jul 2026.
