Active clinical trials for "Melanoma"

This study is a diagnostic study. Patients and healthy volunteers were recruited from clinically suspected or confirmed melanoma patients to undergo 18F-PEG3-FPN PET/MR or PET/CT imaging to observe the response of the subjects after drug injection, and evaluate the efficacy of 18F-PEG3-FPN PET imaging in the diagnosis and staging of melanoma compared with 18F-FDG PET imaging. PET/CT imaging was performed in patients with contraindications to MR. The subjects underwent 18F-PEG3-FPN and 18F-FDG PET/MR or PET/CT imaging at an interval of two days, respectively. The general information, clinical data, blood routine, liver and kidney function indexes, 18F-PEG3-FPN and 18F-FDG PET/MR or PET/CT imaging results and other imaging data of the patients and volunteers were collected, and the histopathology of biopsy or surgical specimen was taken as the final diagnostic criteria. This study plans to set the sample size as 50 cases.

Uveal melanoma (UM) is the most common type of cancer inside the eyes of adults. Almost half of all patients diagnosed with UM will eventually develop metastases. Once metastases occur, the median patient survival is short. In this trial, we will test if treatment with Melatonin after primary tumor diagnosis can prevent or delay the development of metastases. 100 patients diagnosed with primary UM will be randomized to either treatment with Melatonin tablets (20 mg at night), or to a control group. Both groups will be followed for 5 years. At 5 years, the number of patients that have developed metastases in the Melatonin and control groups will be compared (primary outcome measure).

Researchers are trying to find ways to improve the management of people with intermediate or high risk resected cutaneous melanoma or with primary uveal melanoma. This research study is investigating using a new blood test to decide when to give a drug called tebentafusp. Tebentafusp has been used in clinical trials in patients with advanced cutaneous and uveal melanoma. This study is designed to determine if tebentafusp can help patients with cutaneous or uveal melanoma live longer.

The goal of this clinical trial is to evaluate the efficacy and safety of Endostar combined with Toripalimab in the adjuvant treatment of resectable stage III-oligometastatic stage IV melanoma, and to find effective biomarkers of efficacy based on tumor paraffin tissue specimens and peripheral blood. The main questions it aims to answer are: The efficacy and safety of the combination treatment regimen; Finding suitable biomarkers can refine the patients with effective treatment After a series of evaluation, if the participants meet the inclusion and exclusion criteria and are evaluated by the investigator, they will formally enter the study observation period and receive the following treatments Endostar: The dose of 210 mg (14 vials) is administered by intravenous pump from Day 1 to Day 3 of each course, every 4 weeks as a cycle, until disease recurrence, metastasis or intolerable toxicity, and up to 6 courses of administration. Toripalimab: 3 mg/kg by intravenous drip every 2 weeks (Day 1 and Day 15 of each cycle) in a 4-week cycle until disease recurrence, metastasis, or intolerable toxicity for up to 1 year (about 13 cycles).

The objective of this study is to construct a noninvasive approach using 68Ga-THP-APN09 PET/CT to detect the PD-L1 expression of tumor lesion in patients with lung cancer, melanoma and other solid tumor to identify patients benefiting from anti-PD-(L)1 treatment.

This study is for women with breast cancer and for adults with melanoma. Breast cancer is a type of cancer when cells in the breast turn into cancer cells, which may grow out of control. Melanoma is a type of skin cancer that starts in cells called melanocytes. These cells make a substance called melanin which gives the skin its color. In this study, people will have surgery to remove the lymph node closest to the site of their cancer. This lymph node is called the sentinel node. This is done to check if the cancer has spread from the original site to the sentinel node. This procedure is called a sentinel node biopsy. This study will provide more information on a potential new dye, called ASP5354, used in sentinel node biopsies. ASP5354 may help to show the lymph nodes more clearly during surgery. This will help the surgeon find the lymph node closest to the site of the cancer (sentinel node). The main aim of the study is to find the best dose of ASP5354 that clearly shows the lymph nodes during surgery. This is an open-label study. That means each person in the study and the study doctors knew that person received ASP5354. Each person will only receive 1 dose of ASP5354. This dose will consist of 2 to 4 injections of ASP5354 around the cancer site. Small groups of people will each receive a different dose of ASP5354. The first group will receive a low dose of ASP5354. If the lymph nodes are clearly seen, the next group will receive a lower dose of ASP5354 and the following group will receive a dose of ASP5354 that is higher than the dose the first group received. Then, the results will be checked by an independent panel of experts. Depending on the results, the next groups may start on the current doses of ASP5354 or may receive a higher dose. In this study, up to 6 doses of ASP5354 may be given, but each person only receives 1 of these doses. People that want to take part in the study will be checked by a study doctor. This will be on a separate visit before their surgery. Before surgery, people who take part in the study will be asked if they have any other medical problems. They will have a physical exam, an ECG to check their heart rhythm, and have their vital signs checked (blood pressure, pulse rate, and breathing rate). Other checks will include some blood and urine samples taken for laboratory tests. During surgery, a study surgeon will inject ASP5354 near the cancer site. They will record how clearly they can see the lymph nodes. Some blood samples will be taken for laboratory tests and an ECG will be done. After their surgery, people will be asked if they have any other medical problems. People will return to the hospital 9 days later for a check-up. The check-up will include a physical exam, an ECG to check their heart rhythm, and a check of their vital signs (blood pressure, pulse rate, and breathing rate). Other checks will include some blood samples taken for laboratory tests. People will be asked if they have any medical problems and asked to complete a feedback survey.

This is a single centre, correlative, longitudinal, biomarker study that aims to describe the metabolic features of human melanoma using mass spectrometry.

The aim of this study is to evaluate a new method of follow-up for patients with low and intermediate risk (stages IA-IIA) melanoma. The investigators will compare different tools for patient support and education combined with clinician supported skin self-examination (SSE) to the current standard-of-care. The hypothesis is that meta-cognitive strategies and clinician supported SSE can lower fear of cancer recurrence (FCR) and promote effective SSE on a regular basis without compromising the detection of new primary melanomas and/or metastases.

Among the mechanisms responsible for resistance to immunotherapy, metabolism seems to play a major role. A better understanding of tumor metabolism appears to be absolutely necessary in order to propose efficient therapeutic alternatives to target tumor cells without exerting a deleterious effect on the cells responsible for the anti-tumor immune response. The main objective is to evaluate metabolism modulations in melanoma cells extracted from metastases of patients sensitive and resistant to immunotherapies (anti-PD1 or anti-PD1+anti-CTLA4).

This phase II trial investigates the possible immune effects of two different diets targeting the gut microbiome in patients with stage III-IV melanoma that has been removed by surgery (resectable), has spread to other places in the body (metastatic), or is unable to be removed by surgery (unresectable), and who are being treated with the immunotherapy drugs pembrolizumab or nivolumab as part of their standard of care. Both diets are whole foods diets that meet the American Cancer Society recommendations for cancer patients, but they will vary in fiber content. The purpose of this trial is to learn about the effects of dietary interventions on the structure and function of the gut microbiome in patients with melanoma being treated with standard of care immunotherapy (pembrolizumab or nivolumab).
