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.
This phase II trial tests how well tebentafusp works to shrink tumors prior to primary treatment with surgery or radiation in patients with uveal (eye) melanoma that has spread to nearby tissue or lymph nodes (locally advanced) or that cannot be removed by surgery (unresectable). Tebentafusp is a drug that binds to melanoma tumor cells as well as immune cells called T-cells. This binding causes an immune response against the melanoma cells, which leads to tumor cell death. Tebentafusp has been approved for the treatment of locally advanced and unresectable uveal melanoma. Giving tebentafusp before primary treatment with surgery or radiation may help shrink the tumor, prevent the...
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.
This clinical trial aims to evaluate the effectiveness of a new treatment approach for patients with stage III or IV melanoma that has spread to other parts of the body but can still be surgically removed. The study combines two treatments: LTX-315 and pembrolizumab. Melanoma that has spread to other parts of the body can often be treated with surgery. Despite surgery, there is a high risk of the cancer coming back. Pembrolizumab, an immune checkpoint inhibitor, can reduce this risk when given after surgery. Recent studies have shown that giving pembrolizumab before surgery, along with post-surgery treatment, might be more effective than giving it only after surgery. However,...
This research study is studying the drugs called NeoVax (a new type of personalized neoantigen vaccine) in combination with CDX-301 and Nivolumab or Pembrolizumab as a possible treatment for melanoma. The names of the study drugs involved in this study are: - Personalized Neoantigen peptides (which combined with poly-ICLC make the vaccine NeoVax) - Poly-ICLC (Hiltonol) - CDX-301 - Nivolumab (Opdivo) - Pembrolizumab (Keytruda)
Medical scientists want to find better ways to treat neuroblastoma and to find ways to prevent the tumor from growing back. To do this, they need more information about the characteristics of neuroblastoma cells. Therefore, they want to study samples of neuroblastoma tissues and neuroblastoma and normal cells in the blood and bone marrow that may be related to the growth of neuroblastoma cells. Doctors and other medical scientists also want to find better ways to detect and measure neuroblastoma to improve the ability to follow the response of tumor cells to therapy.
