About this study

Official title: A Prospective, Phase II Study of Lutetium Lu 177 Dotatate (LUTATHERA®) in Patients With Inoperable, Progressive Meningioma After External Beam Radiation Therapy

This phase II trial studies how well lutathera works in treating patients with meningioma that cannot be treated with surgery (inoperable) and is growing, spreading, or getting worse (progressive) after external beam radiation therapy. Lutathera is a radioactive drug administered in the vein that is designed to target and kill tumor cells. The goal of this study is to determine whether this drug is safe and effective in treating meningiomas that progress after radiation treatment. WHO Grade I and Cohort WHO II/III cohorts will be evaluated.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the efficacy of lutetium Lu 177 dotatate (LUTATHERA) treatment in patients with recurrent grade 1 meningioma as measured by 6-month progression-free survival (PFS) rate.

II. To estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 2 or 3 meningioma as measured by 6-month PFS rate.

SECONDARY OBJECTIVES:

  1. To determine the overall survival (by grade cohort) of patients with recurrent meningioma during or after treatment of LUTATHERA.

II. To determine the progression-free survival (by grade cohort) of patients with recurrent meningioma during or after treatment of LUTATHERA.

III. To determine the toxicity of LUTATHERA treatment in patients with recurrent meningioma.

CORRELATIVE RESEARCH OBJECTIVES:

  1. To assess the impact of treatment on the patient's quality of life (QOL) using the Promise-10, Brief Fatigue Inventory (BFI), and Mayo Patient Survey National Comprehensive Cancer Network (NCCN)-Functional Assessment of Cancer Therapy (FACT) Brain Symptom Index Questionnaire-24 (FBrSI-24) (version 2) instruments.

II. To compare the response assessment between standard of care brain magnetic resonance imaging (MRI) and gallium Ga 68-DOTATATE (68Ga-DOTATATE) positron emission tomography (PET) imaging.

III. To determine the best objective response (Macdonald criteria) of patients with recurrent meningioma during or after treatment of LUTATHERA.

IV. To determine the duration of local control with death as a competing risk (by grade cohort) of patients with recurrent meningioma during or after treatment of LUTATHERA.

  1. To perform a quantitative dosimetric analysis of radiation dose delivered with lutathera:

Va. To determine intratherapeutic dosimetry for the target meningioma; Vb. To correlate treatment response of lutathera with target dose received; Vc. To determine intratherapeutic dosimetry for kidneys and other abdominal organs.

OUTLINE:

Patients receive gallium Ga 68-DOTATATE intravenously (IV) and undergo a PET/MRI or PET/computed tomography (CT) before cycles 1 and 4. Patients then receive lutetium Lu 177 dotatate IV over 30-40 minutes. Treatment repeats every 8 weeks for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo MRI on study and during follow-up, as well as blood sample collection and possible single photon emission computed tomography (SPECT)/CT dosimetry on study.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for up to 5 years.

    Defined as the number of evaluable patients not having progressive disease or death within six months of the first day of treatment.

    Measured: At 6 months after starting treatment

Secondary outcomes (3)

  1. Overall survival

    Defined as the time from the first day of treatment to death due to any cause.

    Measured: Up to 5 years

  2. Progression free survival - overall

    Defined as the time from the first day of treatment to the earliest date documentation of disease progression.

    Measured: Up to 5 years

  3. Incidence of adverse events

    Will be assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The maximum grade for each type of adverse event will be recorded for each patient.

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Gallium Ga 68-DOTATATE, Lutetium Lu 177 Dotatate and Magnetic Resonance Imaging in people with Grade 1 Meningioma and Grade 2 Meningioma, run by Mayo Clinic 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 17 inclusion and 19 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: looking for participants now, as of the sponsor's last update on 13 Oct 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?

Contact Clinical Trials Referral Office (855-776-0015, mayocliniccancerstudies@mayo.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival - 6 months (time frame: At 6 months after starting treatment). 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 NCT04082520.

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 13 Oct 2026.
