Lutathera for the Treatment of Inoperable, Progressive Meningioma After External Beam Radiation Therapy

Overview

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 cancer cells. The goal of this study is to determine whether this drug is safe and effective in treating meningiomas that progress after radiation treatment.

Detailed Description

PRIMARY OBJECTIVES:

I. 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:

I. 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:

I. To assess the impact of treatment on the patient?s quality of life (QOL) using the Promise-10, Brief Fatigue Inventory (BFI), European Quality of Life Five Dimension Five Level (EQ-5D-5L), 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 (McDonald 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.

V. 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 before cycles 1 and 4. Patients then receive lutetium Lu 177 dotatate intravenously (IV) over 30-40 minutes. Cycles repeat every 8 for up to 6 months in the absence of disease progression or unacceptable toxicity.

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

Clinical Trial Outcome Measures

Primary Measures

  • Progression-free survival
    • Time Frame: At 6 months after starting treatment
    • Will be defined as the number of evaluable patients not having progressive disease or death within six months of the first day of treatment divided by the total number of evaluable patients. The proportion of successes in each cohort will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the approach of Clopper-Pearson. There will be no formal comparison of rates among the two different grade cohorts of patients.

Secondary Measures

  • Overall survival
    • Time Frame: From the first day of treatment to death due to any cause, assessed up to 5 years
    • The distribution of survival time for both cohorts will be estimated using the method of Kaplan-Meier. No formal comparison will be made among the cohorts.
  • Progression free survival
    • Time Frame: From the first day of treatment to the earliest date documentation of disease progression, assessed up to 5 years
    • The distribution of time to progression will be estimated using the method of Kaplan-Meier (Kaplan et. al 1958). No formal comparison will be made among the cohorts.
  • Incidence of adverse events
    • Time Frame: Up to 24 months
    • Will be assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03. The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the adverse event(s) to the study treatment will be taken into consideration.
