Active clinical trials for "Brain Neoplasms"

This is a multicenter, randomized controlled, double-blind clinical trial. The study is designed to evaluate the efficacy and safety of high-dose Almonertinib versus Osimertinib in the second-line treatment of patients with EGFR mutations in advanced NSCLC with brain metastases.

Background: For newly-diagnosed patients with brain metastasis, conventional whole-brain radiation therapy (WBRT) might still remain a common palliative management even for those with brain oligometastases. However, WBRT-related late consequences, particularly a decline in neurocognitive functions (NCFs), are a major concern. Actually, WBRT-related neurocognitive dysfunction is usually characterized as deterioration involving learning and memory, in which the extremely radiosensitive hippocampus indeed plays a critical role. In order to postpone or mitigate the effect of conventional WBRT-induced neurocognitive impairments, there have been some strategies and options in clinical practice. Among them, the technique of highly precise and accurate stereotactic radiosurgery or stereotactic radiotherapy (i.e., hypofractionated stereotactic radiotherapy, HS-SRT) might have been widely administered in irradiating purely focal metastatic foci in cancer patients with a limited number of brain metastases. Methods: Newly-diagnosed cancer patients harboring 1-3 brain metastatic lesions are eligible if they are still in a fair/good performance status. All recruited patients should receive baseline brain MRI examination and pre-radiotherapy neurocognitive assessment. Sticking to the principles of stereotactic radiosurgery/radiotherapy (SRS/SRT), treatment planning will be designed via the technique of volumetric-modulated arc therapy (VMAT) to achieve both satisfactory in-field local control (but assuring of hippocampal avoidance) and a tolerably low incidence of radiation necrosis, a course of hypofractionated stereotactic radiotherapy (HF-SRT) is delivered within 2 weeks with a cumulative dose of 3000 - 3500 cGy in 5 fractions. Accordingly, a battery of neuropsychological measures, which includes 7 standardized neuropsychological tests (e.g., executive functions, verbal and non-verbal memory, working memory, and psychomotor speed), is used to evaluate neurocognitive functions for our registered patients. The primary outcome measure is cognitive-deterioration-free survival, which is defined mainly as the time from enrollment to a NCF decline of exceeding than 1 SD away from the baseline involving at least one of the assessed NCF tests. Additionally, patients who expire before 6 months or are alive but fail to undergo all the neurocognitive testing administered would also be defined as suffering from cognitive deterioration. There are quite a few secondary endpoints of interest, including the patterns of (CNS) failure, actual local control rates, time to (CNS) progression, and cumulative incidence of radiation necrosis. Expected results: This prospective neurocognitive study aims to examine thoroughly the impact of the technique of highly focal brain irradiation administered with a course of hypofractionated SRT delivered to brain metastatic lesions merely (but sparing hippocampal structures), on neurocognitive performance, time to (CNS) progression, and patterns of (CNS) failure, in patients with brain oligometastases and a fair/good performance status. It is anticipated that (in-field) local control would be durable and that neurocognitive outcomes would also be maintained favorably. Moreover, we also expect that the patterns of (CNS) failure and the individual time to progression will be clearly demonstrated in this prospective longitudinal neurocognitive study.

Brain tumors are the second most frequent malignant diseases in children and adolescents. In the study the short and medium term consequences of proton therapy on cognitive processes in particular on executive functions in pediatric patients shall be highlighted/analysed/evalutated. In a second step, these results are to be compared with a group of children and adolescents who had only /exclusively had operative therapy and with a healthy control group. Thus, the extent to which these treatment options differ in terms of their short and medium-term effect is assessed. Methods of neurocognitive/neurophysiology brain research approaches are applied that may potentially visualize even small / subtle changes in mental activities/neurocognitive function. Therefore the effects of treatment can be evaluated and the neuropsychological outcome of children and adolescents with brain tumors can be improved.

Gliomas are the most frequent type of primary brain tumors in adults; among them glioblastoma multiforme (GBM) is the most malignant, being associated with the worst prognosis. Glutamate (Glu) is an aminoacid, responsible for essential functions in the Central Nervous System (CNS), acting both as metabolite and neurotransmitter. It is essential for regulating cellular metabolism and developmental synaptogenesis, cellular migration, differentiation and death. Recent scientific evidences have demonstrated alteration in Glu synthesis and signaling being directly involved in GBM growth and invasion

This will be the first in-depth study to evaluate pretreatment and 12 months post-treatment, neurocognitive and psychological outcomes of children with brain tumor and blood cancer in Pakistan. The investigators will also determine the socioeconomic burden of pediatric brain tumors in low middle-income region and the association of micro RNA and protein markers with neurocognitive outcomes in PBT and blood cancer children. A prospective cohort study with a follow-up of 12 months at the Aga Khan University Hospital, Karachi, Pakistan and Jinnah postgraduate Medical Centre , Karachi, Pakistan will be conducted. After taking consent/ assent the investigators will recruit 80, 5-21 years old children with newly diagnosed brain tumors presenting with any stage, who have not undergone any treatment. Trained psychologist will assess the neurocognitive outcomes by the Slosson scale, Raven's progressive matrices and Wechsler Intelligence Scale for children (WISC V) and Wechsler Adult Intelligence Scale (WAIS-IV) tools. The Quality of life and depression of the children will be determined by PedQL and Revised Children's Anxiety and Depression Scale (RCADS) and hospital anxiety and depression scale (HADs) respectively . The financial burden of the disease on the family will be measured on a visual analog scale ranging from no burden (0) to very large burden (100) and the parents QoL and disrupted schedule, financial problems, lack of family support, health problems and the impact of caregiving on caregiver's self-esteem will be assessed by Pediatric Quality of Life Inventory PedQl (family module) and Caregiver Reaction Assessment (CRA) tools respectively. The serum micro RNA (mi-21, mi-10b and mi-210) and protein markers (GFAP, NSE and S100β) will be assessed by qRT-PCR and ELISA.

Despite some encouraging data, systemic treatment of CNS metastases from solid tumors remains experimental. Better knowledge on the evolving epidemiology and biology of BM are key elements for the development of new treatment strategies and identification of promising therapeutic targets for new compounds. Further biological findings may help to better understand the heterogeneity between the primary tumor and the CNS metastases and to identify new targets for therapy thus improving patients' outcome. In this context, the Oncodistinct network and the Jules Bordet institute propose to build a multidisciplinary Brain Metastases Clinical Research Platform called BrainStorm. The BrainStorm program will focus on patients with newly diagnosed non-CNS metastatic solid tumors with high risk of developing CNS metastases and will allow building a large clinico pathological database for CNS metastases including ctDNA analyzes from CSF samples. Substudies will be proposed at each time-period with the final objective to develop innovative treatment approaches and strategies.

This study will assess cognitive function in patients with a primary brain tumour treated with radiation therapy (RT) to generate radio-sensitivity and volume effect parameters for the development of cognitive dysfunction. All types of brain tumours apart from glioblastoma will be included.

This is a pilot study to test the feasibility of implementing a strict classic ketogenic diet among a population of children with recurrent or progressive and refractory brain tumors. Eligible participants will be admitted to the neurosciences floor for 5 days to begin the ketogenic diet either orally, by gastrostomy tube or via nasogastric tube. During the inpatient stay, they will be extensively educated on the diet restrictions and rules. Participants will then continue on the diet at home returning about 17 times over the next 12 months. Daily logs will be kept tracking diet changes, bowel movements and urine ketones. Blood will be collected during the inpatient stay and at all visits for both standard clinical care and research testing.

The primary objective is to evaluate the intracranial efficacy of pemetrexed/carboplatin chemotherapy and lazertinib combination therapy after osimertinib failure in EGFR-positive non-small cell lung cancer patients with brain metastasis. The primary endpoint is the incracranial objective response rate (iORR). Secondary endpoints are intracranial progression free survival, (iPFS), objective response rate (ORR), duration of response (DoR), disease control rate, (DCR), overall survival (OS), the pattern of treatment failure, intracranial salvage treatment rate, and toxicity. Patients should take lazertinib 240 mg (80 mg, 3 tablets) once a day at the same time as possible before meals. Chemotherapy will be administered on the 1st day every 3 weeks. (Pemetrexed 500mg/m2, Carboplatin AUC x 5 mg/mL.min) One cycle of treatment is defined as continuous administration for 21 days. The treatment will be applied to the all patients until documented evidence of disease progression, unacceptable toxicity, noncompliance, or withdrawal of consent, or the investigator decides to discontinue treatment, whichever comes first. If the investigator decides to reduce the dose due to an adverse reaction during the administration of lazertinib 240 mg, the dose may be reduced to 160 mg (80 mg, 2 tablets) of lazertinib. Pemetrexed and carboplatin can be administered in reduced doses according to the principles of each institution.
