Laser Interstitial Thermotherapy (LITT) Combined With Checkpoint Inhibitor for Recurrent GBM (RGBM)

The purpose of this study is to test the side effects and efficacy of using Laser Interstitial Thermotherapy (LITT) combined with Pembrolizumab. LITT is a minimally invasive surgical technique that uses a laser to heat brain tumors. Pembrolizumab is an investigational (experimental) drug that works by helping participants' immune system work correctly to detect and fight cancer cells. Pembrolizumab is experimental because it is not approved by the Food and Drug Administration (FDA), for this use, though it is approved to treat other cancers.

A Trial of Belzutifan (PT2977, MK-6482) Tablets In Patients With Advanced Solid Tumors (MK-6482-001)

The primary objective of this study is to identify the maximum tolerated dose (MTD) of belzutifan Tablets and/or the recommended Phase 2 dose (RP2D) of belzutifan Tablets in patients with advanced solid tumors

Prognostic Potential of Olfactory Function in Glioblastoma: a Prospective Observational Study

The study aims to investigate the prognostic significance of olfactory function in patients with glioblastoma. We are examining olfactory function at various points during therapy and correlating the results with survival data. In addition, neurocognitive tests will be carried out to correlate the results of olfactory function with the patient's cognitive abilities. Investigations into the quality of life and psychological condition of the patients are also performed. In addition to the cohort of glioblastoma patients, there is a control cohort without tumor disease in which the olfactory testing is also carried out in order to have a comparison.

Safety, Pharmacokinetics and Preliminary Efficacy of CS231295 in Advanced Solid Tumors

This trial is a single-arm, open-label, first-in-human study of CS231295, comprising two phases: dose escalation (including single-dose and multiple-dose) and cohort expansion. The Dose-Limiting Toxicity (DLT) observation period includes 6 days for single-dose and the first cycle (28 days) for multiple-dose. The overall study consists of screening period, treatment period, and follow-up period. The primary objectives of this study are to evaluate the safety, tolerability and pharmacokinetic (PK) characteristics of CS231295 in patients with advanced solid tumors, and to recommended Phase 2 dose(s) (RP2D) of CS231295 in appropriate tumor(s).

Oral Capecitabine and Temozolomide (CAPTEM) for Newly Diagnosed GBM

The purpose of this study is to evaluate the safety and efficacy of administering the medication capecitabine along with temozolomide when you start your monthly regimen of oral temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM). Capecitabine is an oral chemotherapy that is given to patients with other types of cancer. The study will evaluate whether the dosage of 1500 mg/m2 of capecitabine is tolerable after radiation, when taken along with temozolomide. It will also try to determine if the medication capecitabine helps patients respond to treatment for a longer period of time compared to just temozolomide alone, which is the standard of care.

CSF Proteomic Characterization of Glioblastomas

The goal of this observational study is to identify proteins that can be found in the cerebrospinal fluid (CSF) of patients with grade IV brain tumors, specifically glioblastomas, and correlate these proteins with progression free survival, overall survival and performance status (functionality). All participants with high probability of glioblastoma will initially be included, final inclusion will be dependent on the definitive histopathological diagnosis of the tumor. The main question is: Can the researchers identify a proteomic profile in CSF from study participants with glioblastoma in association with a longer progression free survival? Participants will undergo the following procedures, that do not deviate from normal standard diagnostic care. 1. Lumbar puncture to obtain CSF. 2. Blood draw. 3. Trans-surgical tissue sample of the brain tumor. Additionally participants will be planned for follow up appointments every 3 months following the first 12 months after the surgical tumor resection.

Study Evaluating the Efficacy of Radiotherapy With SIB-IMRT, Associated With Temozolomide in Glioblastomas

Glioblastoma (GBM) is the most aggressive and most frequent brain tumour. Approximately four people per 100,000 inhabitants are diagnosed with this disease every year. The standard treatment comprises surgical resection (whenever possible), normofractionated radiotherapy at a dose of 60Gray (Gy) and temozolomide (TMZ). Median overall survival in these patients is 14.6 months \[13.2-16.8\]. In a previous phase I clinical trial, dose escalation tolerance using simultaneous-integrated boost intensity-modulated radiation therapy (SIB-IMRT) technic has been evaluated. The investigator demonstrated that SIB-IMRT until a dose of 80Gy in 32 daily fractions, associated with TMZ is feasible and well tolerated by patients with glioblastoma. The aim of this present phase II clinical trial is to evaluate the overall survival at 18 months for patients with glioblastoma receiving TMZ, according to standard protocol, associated to radiotherapy delivered at 80Gy using SIB-IMRT technic. The first planning target volume (PTV), including oedema and tumour highlighted on T2 flair magnetic resonance imaging (MRI) sequences, will receive 60.8Gy in 32 daily fractions. The second PTV, including tumour highlighted on T1 MRI sequences, will receive 80.0Gy in 32 daily fractions. Secondary objectives are tolerance, survival free progression and quality of live evaluations. Sixty seven patients will be enrolled in this present trial.
