Active clinical trials for "Melanoma"

This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

A postmarketing Cohort study of Melanoma patients treated with IMLYGIC (Talimogene Laherparepvec) in clinical Practice to Characterize the risk of herpetic infection with detection of Talimogene Laherparepvec DNA among patients, close contacts, and health care providers; and long term safety in treated patients for up to 5 years after the first IMLYGIC dose.

The purpose of this study is to establish a prospective observational cohort of cancer immunotherapy patients with GI side effects in order to identify biomarkers that predict GI complications due to treatment.

This is a run-in, randomized, non-comparative, phase II study designed according to a two stages optimal design by Simon. This phase II design will be preceded by a safety evaluation after the first cohort of 6 patients to preserve a high-grade of overlapping and/or unexpected toxicity rate. The study will assess the immune-objective response rate (iORR) (assessed using iRECIST criteria) of nivolumab combined with ipilimumab and guadecitabine or nivolumab combined with ipilimumab, in Melanoma and non-small cell lung cancer (NSCLC) patients resistant to anti-PD-1/PD-L1 therapy. Immune biologic correlates to treatment will be assessed as exploratory endpoints.

This trial collects multiple tissue and blood samples, along with medical information, from cancer patients. The "Cancer Moonshot Biobank" is a longitudinal study. This means it collects and stores samples and information over time, throughout the course of a patient's cancer treatment. By looking at samples and information collected from the same people over time, researchers hope to better understand how cancer changes over time and over the course of medical treatments.

Malignant melanoma, is a kind of malignant tumor derived from melanocytes. It is common in skin, mucous membrane, eye choroid and other parts. Melanoma is one of the fastest growing malignant tumors with an annual incidence rate of 3-5%. In 2012, there were 232000 new cases of melanoma and 55000 deaths worldwide. Though, the incidence rate of melanoma is relatively low in China, it has been increasing rapidly in recent years. Melanoma has seriously endangering the health of Chinese people. Patients with stage Ⅳ melanoma have a poor prognosis. According to statistics, the median survival time of stage M1a melanoma is 15 months, while stage M1b is 8 months. The median survival time of bone metastasis melanoma is 6 months, while liver and brain metastasis is 4 months. The overall median survival time of metastatic melanoma is only 7.5 months, and the 2-year survival rate is 15%. For patients with advanced melanoma, dacarbazine is the only chemotherapy drug approved by NMPA, but its overall effective rate is only 13.4%, and the median survival time is 5.6 ~ 11 months. Therapies(new drugs or new combination treatments)with higher remission rate and longer survival are urgently needed for patients with advanced melanoma.

The microbiome has the potential to serve as a robust biomarker of clinical response to immunotherapy. Additionally, microbial manipulation, through diet, exercise, prebiotics, probiotics, or microbially-derived metabolites, may prove to be beneficial in promoting anti-tumor immune responses. However, large prospective studies in humans with longitudinal sample collection and standardized methods are needed to understand how microbiota and their byproducts affect cancer therapies, particularly among patients undergoing identical therapy but experiencing different outcomes. The proposed observational study builds upon these hypotheses by proposing a large cohort design to further assess the associations between the gut microbiota (composition and function), host immune system, and ICI treatment efficacy across multiple cancer types.

Skin diseases can have various origins. However, a number of them are linked to an imbalance in the immune system which will lead to either an excessively strong autoimmune response or a complete lack of response against cancer cells. Indeed, both melanoma and vitiligo are pathologies where the immune system plays an important role in the progression of the disease. Advanced stage melanoma (metastatic lymph node and / or visceral) have a poor prognosis. Although targeted therapies and immunotherapies have improved the outcome for patient however significant proportion of these patients (~ 50%) developed resistance to therapies. Vitiligo is a relatively common dermatosis affecting approximately 0.5% to 1% of the French population. Vitiligo results from the destruction of the melanocytes by the immune system. It is manifested by acquired depigmented macules, well limited and asymptomatic. Patients suffering from this condition have a marked decrease in their quality of life. There has been shown a strong link between vitiligo and melanoma. Indeed, patients with melanoma who develop vitiligo (~ 9% of patients treated with anti-PD-1 drugs) have a better prognosis compared to patients who do not develop vitiligo. Interestingly, in melanoma cases where the immune system is inactive, the investigators have identified a new molecule secreted by melanoma cells, ITGBL1, leading to the exclusion of immune cells, decreased cytokines secretion and decreased immune cell activation. It is therefore essential to better understand the regulatory mechanism of the immune system in patients with vitiligo or in patients with melanoma treated by immunotherapy in order to be able to propose new therapeutic solutions for these patients. No study to date has investigated the expression of ITGBL1 and serum inflammatory markers during the development of melanoma. Likewise in vitiligo, if a loss of ITGBL1 is observed, new treatments could be developed in order to limit the progression of the disease by re-expressing this protein. Thus, the investigators exploratory study will provide the first answers to the predictive value of these markers for these pathologies in order to adapt and develop new treatments.

The study hypothesis is that new imaging agents [203Pb]VMT01 and [68Ga]VMT02 can be safely used in humans without independent biological effect and can be used to image melanoma tumors expressing the melanocortin sub-type 1 receptor (MC1R) by SPECT/CT and PET/CT imaging modalities respectively.

This study investigates the extent to which lifestyle factors including mental health, social support, diet, and exercise are associated with quality of life and melanoma patient outcomes. Knowledge gained from this study may be used to guide the design of prospective clinical trials of lifestyle interventions to improve the outcomes of melanoma patients and assist doctors in counseling their patients.
