177Lu-DOTATATE in Treating Patients with Progressive or High-Risk Grade I-III Meningioma

Inclusion Criteria

• Male or female subjects aged >= 18 years
• Karnofsky performance status >= 60
• Histologically confirmed diagnosis of WHO grade I-III meningioma: * For grade I meningioma, subjects must have: ** Progressive disease after at least surgical resection and radiotherapy, as defined as an increase in size of the measurable primary lesion (bidirectional area) on imaging by 25% or more between scans separated by no more than 12 months or ** Progressive residual tumor after maximal safe resection, be located at or near critical organs at-risk and considered to be high-risk for radiation injury by the treating investigator. Prior external beam radiation therapy is not required for these subjects * For grade II or III meningioma, subjects must have either: ** Progressive disease after at surgical resection and radiotherapy, as defined as an increase in size of the measurable primary lesion (bi-directional area) on imaging by 25% or more between scans separated by no more than 12 months or ** Residual measurable disease after surgery without requirement of progression
• Positive 68Ga-DOTATATE uptake on PET-magnetic resonance imaging (MRI) * Positive uptake is defined as uptake higher than the background and standard uptake value (SUV) ratios adjusted to the liver and spleen uptake (adopted from Krenning score) * 68Ga-DOTATATE uptake in target lesions should be Krenning score >= 2
• Presence of measurable disease defined as at least one lesion measuring >= 10 mm in at least one dimension by contrast-enhanced MRI performed within 30 days prior to study registration
• Multifocal disease is allowed but limited to =< 3 measurable intracranial mass lesions on most recent postcontrast MRI
• Any neurological symptoms must be stable for at least 28 days prior to enrollment and patients should not require steroids to control neurological symptoms
• There is no limit on the number of prior surgeries, radiation therapy, radiosurgery treatments or systemically administered therapeutic agents
• For patients treated with external beam radiation, interstitial brachytherapy or radiosurgery, an interval >= 24 weeks must have elapsed from completion from these therapies to registration unless there is histopathologic confirmation of recurrent tumor or there is new enhancing tumor outside the radiation field (beyond the high dose region or the 80% isodose line)
• An interval of >= 28 days (or 5 half-lives, whichever is shorter) from prior cytotoxic chemotherapy (6 weeks from nitrosoureas), biologic agent, investigational agent or any other systemic agent prescribed for the purpose of treating meningioma
• An interval of >= 28 days from craniotomy and >= 7 days from stereotactic biopsy
• Availability of a paraffin-embedded archival tumor block from most recent tumor resection sufficient to generate at least 8 unstained slides but preferably up to 25 unstained slides; or, if a paraffin tumor block is unavailable, at least 8 unstained slides but preferably up to 25 unstained slides * Report of positive SSTR2 expression by immunohistochemistry in the most recent tumor specimen
• Patients must be willing and able to undergo regular MRI scans of the brain
• Patients must have recovered to Common Terminology Criteria for Adverse Events (CTCAE) grade =< 1 or pretreatment baseline from clinically significant adverse events related to prior therapy (exclusions include alopecia, laboratory values listed per inclusion criteria, lymphopenia, sensory neuropathy =< grade 2, or other =< grade 2 not constituting a safety risk based on the investigator's judgment)
• White blood cell (WBC) >= 2,000/mm^3 (within 21 day of treatment initiation)
• Absolute neutrophil count (ANC) >= 1,000/mm^3 (within 21 day of treatment initiation)
• Platelet count >= 75,000/mm^3 (within 21 day of treatment initiation)
• Hemoglobin >= 8 gm/dL (within 21 day of treatment initiation)
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x laboratory upper limit of normal (ULN) (within 21 day of treatment initiation)
• Creatinine clearance (measured or calculated) >= 50 mL/min OR creatinine levels > 150 uMol/L (1.7 mg/dL) (within 21 day of treatment initiation)
• Total serum bilirubin =< 3 x ULN (except participants with Gilbert's syndrome, who can have a total bilirubin =< 5 x ULN) (within 21 day of treatment initiation)
• Serum albumin level of more than 3.0 g/dL, unless the prothrombin time value was within the normal range (within 21 day of treatment initiation)
• Women of childbearing potential (WOCB) and men able to father a child must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in the study, she must inform her treating physician immediately
• Able to understand and willing to sign an Institutional Review Board (IRB) approved written informed consent document

Exclusion Criteria

• Patients with a clinical diagnosis of NF2 (either by National Institutes of Health [NIH] or Manchester criteria) or with a molecular diagnosis of NF2
• Patients with radiation-associated meningiomas
• Life expectancy =< 6 months
• Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm. This includes treatment with somatostatin LAR within 4 weeks prior to enrollment, or any patient receiving treatment with short-acting octreotide that cannot be interrupted for greater than 24 hours before treatment
• Peptide receptor radionuclide therapy at any time prior to registration
• Known hypersensitivity to somatostatin analogues or any component of the 68Ga- DOTATATE or 77LuDOTATATE formulations
• Known additional malignancy that is progressing or requires active treatment within 2 years of start of study drug. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and in situ cervical cancer that has undergone potentially curative therapy
• Current or planned participation in another study of an investigational agent or investigational device
• Active infection requiring intravenous therapy with antibiotics
• Uncontrolled intercurrent illness including, but not limited to, clinically significant (i.e. active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), congestive heart failure (>= New York Heart Association [NYHA] class II), unstable angina pectoris, or serious cardiac arrhythmia requiring medication

• Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV ribonucleic acid [RNA] if anti-HCV antibody screening test is positive)
• Other severe acute or chronic medical or psychiatric conditions (within the past year) including recent or active suicidal ideation or behavior, or laboratory abnormalities that may increase the risk associated with study participation or treatment on study or may interfere with the interpretation of study results
• Pregnant and/or breastfeeding patients. Women of childbearing potential (WOCBP) must have a negative pregnancy test within 14 days of study entry
