The goal of this clinical trial is to test neoadjuvant dual immunotherapy in Merkel cell carcinoma with the aim to improve recurrence-free survival
The main purpose of this study is to determine the response of Merkel cell carcinoma to pembrolizumab before surgery and to determine whether it further reduces the risk for disease recurrence. Another purpose of this study is to look at the side effects that occur when the experimental drug pembrolizumab is given to people with Merkel cell carcinoma before and after their standard of care surgery to remove the Merkel cell carcinoma.
The purpose of this study is to test the effects of anti-PI-1 inhibitor (TSR-042) or anti-PD-1/anti-TIM-3 combination (TSR-042 / TSR-022) in patients with operable melanoma.
The goal of this clinical trial is to evaluate the safety and efficacy of neoadjuvant radiochemotherapy in the surgical resection of glioblastoma (GBM). The main questions it aims to answer are: - What is the safety profile of neoadjuvant radiochemotherapy in terms of neurological deficit, radionecrosis, edema, headache, wound dehiscence, infection, and cerebrospinal fluid fistula? - What is the efficacy of neoadjuvant radiochemotherapy in terms of progression-free survival, overall survival, cognitive function, and quality of life? Participants will undergo the following tasks and treatments: - Stereotactic biopsy and diagnosis confirmation. ...
This Phase I/II trial studies the ability to stop brain metastases from coming back after treatment with radiosurgery followed by surgical resection. It will also evaluate the side effects of these combined treatments and help determine the best radiosurgery dose. Radiosurgery focuses the x-rays directly to the tumor and cause less damage to the normal tissue in the brain.
This multicentre proof-of-concept study, involving 4 centers, aims to establish the value of fractionated neoadjuvant stereotactic radiotherapy (NaSRT) as a new treatment paradigm for brain metastases (BM) in the frame of the Czech neurooncology network. Most relevant studies published to date used single-fraction radiotherapy and dealt with the inherent bias related to their retrospective nature. The researchers aim to increase the level of evidence for this treatment paradigm together with other similar ongoing studies.
Uveal melanoma (UM) is a rare type of melanoma, with an incidence of 4.4 cases per million in Europe each year. During recent years, different treatment approaches have been tested in patients with metastatic UM. Responses have been reported primarily with localized treatment in patients with a limited number of liver metastases. In cases of diffuse liver involvement or extrahepatic disease, systemic therapies are justified. However, to date, systemic therapies such as targeted therapy with selumetinib or conventional chemotherapy have failed in metastatic UM. Neo-TB is a Phase II, single arm, multicentre clinical trial designed to evaluate efficacy and safety of tebentafusp...
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic...
This is a single institution, open-label, multi-arm, phase I study assessing the safety and immunogenicity of a personalized neoantigen-based personalized DNA vaccine combined with PD-1 blockade therapy in subjects with newly diagnosed, MGMT promoter unmethylated glioblastoma (GBM). Immune checkpoint blockade, specifically those targeting the PD-1/PD-L1 pathways, has shown efficacy in multiple solid and hematologic malignancies. Furthermore, as has been demonstrated in metastatic melanoma, combining PD-1/PD-L1 blockade with other immune checkpoint inhibitors has shown improved objective response rates, though there is a significant increase in serious immune-related adverse...
The purpose of this research study is to learn about the safety and feasibility of giving a personalized DNA vaccine to people with brain tumors that have returned or have been resistant to treatment.
