Metronomic Temozolamide in Patients With Recurrent Glioblastoma
Indication: Subjects with glioblastoma at first relapse after surgery, radiotherapy and first-line temozolomide (TMZ). Objectives: 1. Phase I endpoint: - To determine the maximum tolerated dose (MTD) of CPT-11 administered on days 8 and 22 in combination with a fixed, continuous, and metronomic regimen of TMZ, given in 28-day cycles. 2. Phase II endpoints: Primary endpoint: Progression-free survival at 6 months. Secondary endpoints: Response rate, toxicity profile, overall survival. Complementary studies: To assess the effect of treatment on plasma concentration of thrombospondin-1 (TSP1), soluble VEGF receptor 1 (sVEGF-1) and...

Modulation of Ciliogenesis in Glioma Stem Cells
The study aims at investigating the cilium-related transcriptome in patients-derived glioblastoma stem cells and the potential impact of modulation of cilium players in vitro, in vivo and ex vivo in glioblastoma brain organoids. Moreover, drugs inhibiting cilia disassembly will be tested. Finally, the potential prognostic role of a cilium-related gene expression signature in glioblastoma will be assessed.

MRI Predictors of Response to Tumor Treating Fields
Patients with glioblastoma, an aggressive brain tumor, are recommended to undergo treatment with tumor treating fields using the Optune device as part of standard of care therapy. While undergoing treatment, patients are monitored regularly with brain MRI scans to look for tumor progression, but there are currently no means to predict which, or when, patients will progress. The purpose of the current study is to prospectively analyze these MRI scans to look for subtle imaging markers that can predict for future brain tumor progression while undergoing tumor treating field therapy.

Multi-parametric MRI/Fluorine-18 Fluciclovine PET-CT in Glioblastoma
Glioblastoma is the most common adult brain tumour with approximately 2000 new cases each year in the UK. Optimal treatment consists of surgery followed by radiotherapy and chemotherapy but despite this survival is poor with only 10% of patients alive at 5 years. Standard imaging (MRI and CT) may not detect the full extent of tumours before treatment and it can be difficult to assess how the tumour is responding to treatment. The study aims to evaluate more advanced imaging techniques to see if they are better at mapping the whole tumour and assessing response to treatment. Two different imaging techniques will be assessed: Positron Emission Tomography - Computed Tomography...

Neoadjuvant PD-1 Antibody Alone or Combined With DC Vaccines for Recurrent Glioblastoma
Glioblastoma multiforme (GBM) are the most prevalent malignant tumor in central nervous system. At recurrence, no clear standard-of-care therapy is agreed for recurrent GBM (rGBM) and median overall survival is estimated to rarely exceed 6-9 months with effective therapies. Neoadjuvant therapy with anti-PD-1 monoclonal antibodies were confirmed to be helpful to extend survival in rGBM. Vaccine, dendritic cells (DCs) pulsed with glioblastoma stem-like cell (GSC) antigens (GSC-DCV), could extend survival for GBM patients in our previous clinical study (PMID: 30159779). The purpose of this study is to evaluate the safety and efficiency of using the neoadjuvant therapy with PD-1...

Neoadjuvant Temozolomide Combined With Simultaneous IMRT for Treatment of Glioblastoma
This study is a prospective, multi-center, randomized controlled clinical study. Indications: Glioblastoma diagnosed after surgery (WHO grade IV). The patient received conventional postoperative concurrent radiotherapy and chemotherapy, or neoadjuvant temozolomide combined with concurrent increased intensity-modulated radiotherapy. According to data from previous clinical trials, conventional doses of concurrent radiotherapy and chemotherapy PFS 6.9 months neoadjuvant temozolomide combined with concurrently increased intensity-modulated radiotherapy PFS 13.7 months, an estimated 20% leakage rate, and a total sample size of 80 patients.

Neuradiab® Combined With Bevacizumab (Avastin) Therapy in Patients With Recurrent Glioblastoma Multiforme
Bradmer Pharmaceuticals, Inc. (Bradmer) is requesting approval to study the safety of Neuradiab® when combined with Bevacizumab (Avastin) therapy given at a minimum of 30 days after Neuradiab administration in patients with a first or second recurrence of glioblastoma multiforme (GBM), in an attempt to manage life threatening recurrence of Grade IV malignant glioma.
