Active clinical trials for "Melanoma"

This primary purpose of this study is to obtain blood samples from participants with both early and later stages of melanoma (Stage II/III and Stage IV). The researchers hope to better understand an abnormal protein found in many melanoma tumors called the BRAFV600 mutation. There will be two separate cohorts (groups) of participants on this study. You will be placed in one of the Groups. Group 1-For participants with advanced melanoma: Your existing tumor tissue sample will be compared to the blood samples given in order to further analyze and to understand the BRAFV600E gene mutation. Group 2-For participants with stage II/III melanoma: Following surgery, blood samples will be collected and analyzed. Understanding the BRAFV600E gene mutation in melanoma will help the researchers better understand the disease, and help plan treatment options for people with melanoma of all stages in the future.

The purpose of this study, is to evaluate Circulating Melanoma Cell (CMC) changes in Metastatic Melanoma (MM) patients, undergoing treatment with selective inhibitors of mutated BRAF.

This study was a prospective, single-arm, multi-channel, multicenter, non-interventional real-world study to evaluate the safety and efficacy of Toripalimab injection in the treatment of unresectable or metastatic melanoma with previously systemic failure . The study population currently included only in the melanoma cohort-unresectable or metastatic melanoma patients who had previously failed systemic therapy. If new indications are approved during the implementation of the project, patients with new indications using Toripalimab injection will also be included in this study as a new cohort.This study uses offline (physical hospital) and online (DTP pharmacy and Lingke (Yinchuan) Internet hospital) to collect data and information, relying on Lingke technology (Beijing) Co., Ltd. EDC (Medical Research Cloud) database for data collection and processing. The classification of adverse events was based on the general toxicity evaluation standard NCI CTCAE 5.0 of the National Institute of Oncology (Chinese version).

Consecutive patients treated with PD-1 therapy in Qingdao City were included in our study. The effecy and safety of the four PD-1 agents according to clinical outcomes in real world will be studied.

Study of the activity of PD-1 inhibitors in metastatic uveal melanoma

To evaluate the compliance with and perceptions of treatment, as well as health-related quality of life (HRQOL) in surgically resected melanoma patients undergoing HDI or PEG IFN therapy.

Melanoma is the most aggressive skin cancer, with a propensity to metastasize, and is resistant to most of the current therapeutic regimens. Incidence rate of melanoma in patients with MDM (Mal De Maleda, with SLURP-1 mutation) is much higher than normal counterpart. SLURP-1 (lymphocyte antigen 6/urokinase-type plasminogen activator receptor related protein-1) is an allosteric agonist to the nicotinic acetylcholine receptor (nAchR) and it regulates epidermal homeostasis and T-cell function. The preliminary results of comparing human peripheral blood mononuclear cells (PBMCs) from 4 affected and 15 unaffected members from the family with MDM revealed that T-cell activation was impaired in PBMCs with the heterozygous and homozygous SLURP-1 G86R mutation. (2 of affected members developed melanoma.) Since there is currently no effective treatment for metastatic melanoma, identifying novel molecular mechanisms may lead to development of new treatments for metastatic melanomas. Previous study showed that melanoma stem cells (MSCs) are crucial in melanoma pathogenesis: 1.Melanoma contains ABCB5, CD133 and ABCG2 positive cells had enhanced tumorigenic potential. 2.Higher frequencies of cells capable of initiating melanoma xenografts when using IL2Rγ-/- NOD SCID mice. These data confirmed the interaction between T cells and MSCs. In this project, we will investigate the roles of SLURP-1 in melanoma and MSCs. Investigating and verifying the interaction between T-cells from patients with MDM and melanoma cells to confirm the SLURP-1 function of tumorigenesis in xenotransplant mice (IL2Rγ-/- NOD SCID) model. To reveal the role of SLURP-1 silencing in melanoma cell lines by using not only A2058 , A375 and MeWo mwlanima cell lines but also ABCB5+ melanoma cells and ABCB5- melanoma cells through the tumorigenesis, apoptosis,angiogenesis, proliferation, melanosphere formation assays. The aim of this project is to investigate the roles and molecular mechanisms of SLURP-1 in melanoma carcinogenesis, which may improve the development of novel treatments for melanoma.

RATIONALE: A study that evaluates patients' lifestyle, skin, and blood and tissue samples may help doctors understand the risk factors for melanoma relapse. PURPOSE: This clinical trial is studying the risk factors for melanoma in families with melanoma.

The goal with this study is to evaluate the value of dynamic lymphscintigraphy and ultrasoundscanning preoperative in patients with melanomas.

This study will investigate the effects of gut microbiome diversity (richness in terms of many bacterial species in the gut) on responses and side effects of immunotherapy in advanced melanoma patients. Immunotherapy for melanoma is especially damaging for the gut with colitis which can lead to death and significant morbidity with repeated hospital admissions. The richness of the microbiome in the gut may be protective against colitis and other side effects but this needs to be confirmed. There is also some preliminary evidence that the gut microbiome diversity can enhance responses to immunotherapy in cancer but this has been shown in small numbers of melanoma patients.
