Comparing the Radiopharmaceutical Drug, [177Lu]Lu-DOTATATE, to Standard of Care Treatment for Patients With Meningioma That Has Come Back After Prior Treatment

This is an open-label, multicenter, randomized, phase 2 clinical study to evaluate the efficacy of \[177Lu\]Lu-DOTATATE in patients with progressive grade 1-3 intracranial meningioma.

Vismodegib, FAK Inhibitor GSK2256098, Capivasertib, and Abemaciclib in Treating Patients With Progressive Meningiomas

This phase II trial studies how well vismodegib, focal adhesion kinase (FAK) inhibitor GSK2256098, and capivasertib work in treating patients with meningioma that is growing, spreading, or getting worse (progressive). Vismodegib, FAK inhibitor GSK2256098, capivasertib, and abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Psychometric Validation of the MQOL-FR and Descriptive Assessment of Quality of Life in Patients With Meningiomas

This non-interventional study aims to validate the French version of a meningioma-specific quality-of-life questionnaire (MQOL-FR) and to describe health-related quality of life in adults diagnosed with an intracranial meningioma. Participants will be invited to complete online questionnaires through a secure REDCap link. After reading the study information and recording their non-opposition, participants will complete: (1) MQOL-FR (meningioma-specific), (2) EQ-5D-5L (generic health-related quality of life), and (3) FACT-Br (brain tumor-specific quality of life). The questionnaire session takes approximately 30-45 minutes and can be completed in more than one sitting using a REDCap access code. There is no additional visit and no change in usual care. The study will recruit adults (≥18 years) with a meningioma diagnosis based on imaging and/or confirmed by surgery, through the GHU Paris-Sainte-Anne neurosurgery clinic and through patient/community networks. The goal is to obtain 100 fully completed MQOL-FR questionnaires suitable for psychometric analyses.

Observation or Radiation Therapy in Treating Patients With Newly Diagnosed Grade II Meningioma That Has Been Completely Removed by Surgery

This randomized phase III trial studies how well radiation therapy works compared with observation in treating patients with newly diagnosed grade II meningioma that has been completely removed by surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors.

Cognition-preserving Brain Irradiation for Treating Patients With Intracranial Meningioma in the Era of Modern Radiotherapeutic Techniques Including Proton Beam Therapy - a Prospective Study Focusing on Radiological Outcomes and Neurocognitive Endpoints

【Background】For cranial-irradiation-naive patients with intracranial meningiomas at risk of local recurrence, the administration of conformal cranial radiotherapy can enhance tumor control in the current era of modern radiotherapeutic techniques. Life expectancy in patients with intracranial meningiomas, particularly non-malignant meningiomas (WHO grade I and II) is essentially similar to people of general population. However, RT-related neurocognitive function (NCF) sequelae are potentially and seriously a concern which should not be ignored. In terms of the natural course of cranial irradiation-induced NCF decline, it might vary considerably according to the specific domains which are selected to be measured. Early neurocognitive decline principally involves impairments of episodic memory, which is significantly associated with functions of the hippocampus. Additionally, the extent of changes in hippocampal volume after local irradiation may be associated with the hippocampal dosimetry. This study thus aims to investigate the potential cause-effect relationship between the hippocampal dosimetry and radiological outcomes represented by the volumetric changes regarding the contralateral hippocampus; furthermore, the correlation between radiological outcomes and neurocognitive endpoints will be examined and clarified. 【Methods】Patients with cranial-RT-naive intracranial meningiomas may be eligible and therefore enrolled in this prospective study addressing both radiological outcomes and neurocognitive endpoints. All eligible and recruited patients should receive baseline volumetric brain MRI examination and baseline neurobehavioral assessment. Subsequently, conformal cranial irradiation in the era of modern radiotherapeutic techniques (including hypofractionated stereotactic radiotherapy, proton beam therapy volumetric modulated arc therapy) will be utilized in order to reduce the dose irradiating the contralateral hippocampus and other relevant organs at risk. The prescribed dose schemes for treating patients with intracranial meningioma depend on the decision of the radiation oncologist in charge and follow the treatment guidelines at our cancer center. Accordingly, a battery of neurocognitive measures, which includes 9 standardized neuropsychological tests categorized into 5 NCF domains (e.g., executive functions, verbal \& non-verbal memory, working memory, psychomotor speed, and amygdala-related emotion recognition), is used to evaluate neurocognitive performances longitudinally for our registered patients. There will be two co-primary outcome measures in the current study. The main primary outcome will be the correlation between the mean hippocampal dose and the extent of change in hippocampal volume at 6 months after the course of cranial RT. The other primary endpoint will be 6-month cognitive-deterioration-free survival. 【Expected Results】This prospective observational cohort study aims to explore and investigate the cause-effect relationship between the hippocampal dosimetry (i.e., mean dose irradiating the hippocampus, particularly the one contralateral to the lateralization of intracranial meningioma) and the extent of hippocampal atrophy signifying one of the measures regarding radiological outcomes. Simultaneously, predefined standardized neurocognitive outcome measures such as hippocampus-related memory functions and amygdala-related emotion recognition will be obtained prospectively and longitudinally in order to examine whether any meaningfully significant correlation exists between the above radiological outcome measures and neurocognitive endpoints. The mutual associations among hippocampal dosimetry, radiological outcomes including the MRI-delineated hippocampal volume, and neurocognitive endpoints including hippocampus-related verbal/non-verbal memory functions will be examined thoroughly.
