Phase 1b Study PVSRIPO for Recurrent Malignant Glioma in Children

Malignant GliomaAnaplastic Astrocytoma9 more

The purpose of the study is to confirm the safety of the selected dose and potential toxicity of oncolytic poliovirus (PV) immunotherapy with PVSRIPO for pediatric patients with recurrent WHO grade III or IV malignant glioma, but evidence for efficacy will also be sought. The primary objective is to confirm the safety of the selected dose of PVSRIPO when delivered intracerebrally by convection-enhanced delivery (CED) in children with recurrent WHO Grade III malignant glioma (anaplastic astrocytoma, anaplastic oligoastrocytoma, anaplastic oligodendroglioma, anaplastic pleomorphic xanthoastrocytoma) or WHO Grade IV malignant glioma (glioblastoma, gliosarcoma). A secondary objective is to estimate overall survival (OS) in this population.

Small-dose Dexmedetomidine Effects on Recovery Profiles of Supratentorial Tumors Patients From General...

Brain NeoplasmsSurgery

An excellent recovery profile is critical for neurosurgical anesthesia. Rapid awakening, smooth blood pressure and heart rate (HR), a higher degree of coordination, painless or mild pain, as well as better tolerance to endotracheal intubation can avoid can increased intracranial pressure, elevated blood pressure and rapid HR caused by emergency choking, suffocation and agitation, and can reduce postoperative cerebral edema and the risk of bleeding. In addition, it is easy for surgeons to timely evaluate postoperative patients' neurologic function based on the excellent recovery from anesthesia. Up to now, there are many methods and drugs to improve the quality of recovery period, but each of them has some flaws. Dexmedetomidine, an emerging anesthetic adjuvant, exhibits a stable hemodynamic recovery period, and cannot affect evaluation of neurological function with both the sedative and analgesic effects. We propose the following hypotheses: (1) A small dose of dexmedetomidine can be intravenously injected into patients subjected to craniotomy under general anesthesia, in order to improve the recovery profiles and reduce the incidence of emergence agitation. (2) Dexmedetomidine can reduce postoperative pain.

Proteome-based Immunotherapy of Lung Cancer Brain Metastases

Neoplasm Metastasis

Trial Hypothesis: Acute, progressing lethal neurooncological process can be transferred into chronic and non-lethal, the survival rates and life quality can be improved by of control of tumor cells (TCs) quantity and targeted regulation of effector functions of tumor stem cells (TSCs). Brief Description: The first line therapy of brain metastases of lung cancer (BMLC) involves allogeneic haploidentical hematopoietic stem cells (HSCs), dendritic vaccine (DV) and cytotoxic lymphocytes (CTLs). TCs and TSCs are isolated from BMLC sample. Dendritic cells are isolated from peripheral blood mononuclear cells and cultured. Tumor sample provides tumor specific antigens to prepare DV. CTLs are obtained from peripheral blood after DV administrations. HSCs are harvested from closely related donor after granulocyte-colony-stimulating factor (G-CSF) administration. Allogeneic HSCs are administered intrathecally 5 times every 2 weeks, at day 1, 14, 28, 42, 56. DV is given 3 times every 2 weeks (day 14, 28, 42) subcutaneously in four points. CTLs are administered every 2 weeks for 3 months, then 3 times every 1 month intrathecally. Six months after the therapy completion, the efficiency is evaluated and the cohort demonstrating efficiency continues the therapy, while cohort demonstrating no efficiency is transferred to active comparator arm. Second line therapy involves DV with recombinant proteins, CTLs and autologous HSC with modified proteome. Autologous HSCs are mobilized by G-CSF. Carcinogenesis-free intracellular pathways of signal transduction able to respond to targeted regulation of therapeutic cell systems with specific properties, are detected in TSCs using complete transcriptome profiling of gene expression, proteome mapping and profiling of proteins, bioinformation and mathematical analysis and mathematical modeling of protein profiles. To find key oncospecific proteins in TSCs and TCs, the targets for TSCs regulation are detected, as well as protein ligands able to regulate reproductive and proliferative properties of TSCs. Using these data of TCs and TSCs proteins, the cell preparations to initiate adoptive immune response are prepared: DV loaded with recombinant proteins analogous to key tumor antigens, CTLs and autologous proteome-based HSCs. Autologous proteome-modified HSCs, DV and CTLs are administered as in the first line therapy.

EGFR-TKI Concurrent With/Without WBRT in Brain Metastasis From NSCLC

Non-Small Cell Lung Cancer

This is a multi-center phase III randomized controlled study, designing to access whether the efficacy of EGFR-TKI alone on patients with brain metastasis from non-small cell lung cancer (NSCLC) harboring EGFR mutant type is not inferior to EGFR-TKI concurrent with whole brain radiotherapy (WBRT), the primary end point is intracranial PFS (iPFS), while secondary outcomes included overall survival (OS), objective response rate (ORR), evaluation of cognitive function, quality of life (QoL) and adverse events.

Icotinib With Whole Brain Radiation Therapy in NSCLC Patients With Brain Metastases

Non-small-cell Lung Cancer

The purpose of this study is to evaluate the safety and efficacy of icotinib in combination with whole brain radiotherapy for NSCLC patients with brain metastases. The primary endpoint is objective response rate of intracranial lesions.

Phase II Trial of Conventional Versus IMRT Whole Brain Radiotherapy for Brain Metastases

Metastatic Brain Cancer

In this study the patient will receive either whole brain radiation therapy given by intensity modulated radiation therapy (IMRT) or standard conventional radiation. In IMRT therapy radiation dose to the parts of the brain that do not contain tumors is reduced. This study will look to see if this approach results in less hair loss or fewer memory Problems, as compared to the standard technique. The study will also look at the effectiveness of both techniques in controlling the growth of the tumor.

Bevacizumab, Etoposide and Cisplatin Followed by Whole Brain Radiotherapy in Breast Cancer With...

Breast CancerBrain Metastases

The primary objective of A-PLUS trial is to evaluate and compare the efficacy of induction BEEP (bevacizumab preconditioning followed by etoposide and cisplatin) followed by whole bran radiotherapy (WBRT) with WBRT alone in the controlling of brain metastases (BM) in metastatic breast cancer (MBC) patients who have not previously received WBRT. In past 2 years, the research team has demonstrated that BEEP regimen is a highly effective treatment for brain metastases of breast cancer progressing from WBRT by a multi-center phase II study (ClinicalTrials.gov Identifier: NCT01281696). The basic concept of preconditioning, as referred to starting bevacizumab 1 day before chemotherapy, is that the effect of bevacizumab induced tumor vascular normalization takes time to mature. The investigators hypothesized that as induction BEEP decreased the size of brain tumors, the effectiveness of WBRT would be maximized. The investigators expect this integrated approach will do greater benefit to MBC patients with BM, irrespective of subtype.

Fluoro-L-Thymidine Positron Emission Tomography (FLT PET) vs. Adv. Magnetic Resonance (MR) Techniques...

Brain Tumor

The goal of this clinical research study is to learn if using a new imaging solution, 3'-Deoxy-3'-18f-Fluorothymidine, in a positron emission tomography (PET) scan can help doctors determine if your brain lesion is from the tumor returning or the effects of previous treatments. The results of this imaging scan (called an FLT PET scan) will be compared to the results of a Magnetic Resonance Imaging scan, which you have already had or are scheduled to have outside of this study.
