MelanomaLung Cancer

The recent approval of ICB treatments targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death-1 (PD-1/PD-L1) by the US Food and Drug Administration has offered an improved treatment chance for a variety of malignant tumors, including those with a particularly poor prognosis. However, a growing number of studies and case reports show that immunotherapy may accelerate tumor progression in a significant subset of patients ranging from 9% to 27% across multiple histologies and lead to so-called hyperprogressive disease (HPD) that leads to a rapid patient death. During this NIS study, Asylia Diagnostics aims to fill in the first layer of knowledge leading to the identification of predictive biomarkers and biological mechanisms that could be used for the prediction, diagnosis, and treatment of melanoma and NSCLC HPD patients. The study is a retrospective clinical study. During this study basic historical medical information and scrolls from FFPE-preserved biopsies taken prior to immunotherapy treatment will be collected. The nature of the study is not invasive and non interruptive to the standard of care.

Malignant Melanoma Stage IVMalignant Melanoma Stage III

The main objective of this project is to perform a longitudinal monitoring of BRAF and NRAS cell-free DNA in a large cohort of metastatic melanomas patients before treatment and during the follow-up. Results will be compared with clinical data as imaging (based on RECIST criteria) and the activity of lactate dehydrogenase in serum (LDH).

Artificial Intelligence-assisted Evaluation of Pigmented Skin Lesions

MelanomaPigmented Skin Lesion1 more

Malignant melanoma (MM) is a deadly cancer, claiming globally about 160000 new cases per year and 48000 deaths at a 1:28 lifetime incidence (2016). The golden standard, dermoscopy, enables Dermatologists to diagnose with a sensitivity of 40%, and a 8-12% specificity, approximately. Additional diagnostic abilities are restricted to devices which are either unproved or experimental. A new technology of Neuronal Network Clinical Decision Support (NNCD) was developed. It uses a dermoscopic imaging device and a camera able to capture an image. The photo is transferred to a Cloud Server and further analyzed by a trained classifier. Classifier training is aimed at a high accuracy diagnosis of Dysplastic Nevi (DN), Spitz Nevi and Malignant Melanoma detection with assistance from a Deep Neuronal Learning network (DLN). Diagnosis output is an excise or do not excise recommendation for pigmented skin lesions. A total of 80 subjects already referred to biopsy pigmented skin lesions will be examined by dermoscopy imaging in a non interventional study. Artificial Intelligence output results, as measured by 2 different dermoscopes, to be compared to ground truth biopsies, by either classifier decisions or a novel Modified Classifier Technology output decisions. Primary endpoints are sensitivity and specificity detection of the NNCD techniques. Secondary endpoints are the positive and negative prediction ratios of NNCD techniques.

Isolated Limb Perfusion of Melphalan for Melanoma and Sarcoma Treatment

Metastatic Melanoma

In-transit metastases occur in approximately 3% of melanoma patients, can be very symptomatic and the survival in this group may be prolonged. In-transit melanoma metastases are often confined to a limb. In this circumstance, treatment by isolated limb perfusion or isolated limb infusion can be a remarkably effective regional treatment option. Isolated limb infusion (ILI) was introduced in 1992 and is a technique used to deliver regional chemotherapy to treat advanced melanoma confined to a limb. Regional chemotherapy with melphalan delivered by isolated limb perfusion (ILP) or ILI are effective treatment options for in-transit melanoma and are generally well tolerated. ILI is a less invasive and simpler alternative to ILP. Complete response rates are 45- 69% for ILP and 23-44% for ILI. The limb is often warmed to lower temperatures in ILI compared to ILP and the limb becomes progressively more hypoxic and acidotic during ILI, each of these parameters potentially having an effect on outcome. ILP & ILI are used primarily as palliative options when excision of in-transit metastases is unfeasible but can be used as an adjunctive procedure to surgery, for other tumour types such as merkel cell carcinoma, and can be repeated if indicated. For ILI correction of melphalan dose for ideal body weight has been shown to substantially decrease the rates of severe local toxicity while maintaining complete response rates, but overall response rate is reduced. Response to ILI, moreover, is different in upper and lower limbs. ILI for Upper limbs disease is associated with similar complete response rates but lower toxicity than ILI for Lower limbs E disease and with different physiologic sequelae despite comparable methods. The Upper limbs appears relatively resistant to toxic effects of melphalan-based ILI as currently performed, which suggests a potential for further optimization of drug dosing for Upper limbs ILI. Regional therapy is an excellent therapeutic modality for disease limited to a limb and furthermore serves as an excellent model for scientific investigation, both clinical and translational. In this study we want to collect data on isolated limb infusion of chemotherapy to monitor efficacy and tolerability in patients with melanoma metastases of the arm or leg that cannot be removed by surgery.

Immune Monitoring in Metastatic Melanoma

Metastatic Melanoma

The mean survival time in the advanced tumor stage in the presence of distant metastases in malignant melanoma was less than 9 months until a few years ago. Intensive research efforts have led to the development of promising new therapeutic strategies and their clinical application. These include on the one hand mutation-specific inhibitors of important for cell division serine-threonine kinase BRAF such as vemurafenib, dabrafenib and encorafenib and inhibitors of the downstream target protein, the mitogen-activated protein kinase kinase (MEK), such as trametinib, binimetinib and cobimetinib. The group of immunotherapeutics is a second new class of drugs, in which great hope for the treatment of metastatic melanoma is placed. Antibody-mediated blockage of surface molecules expressed on immune cells, referred to as immune checkpoints, results in activation of the immune system. As a result, an anti-tumor immune response is triggered, which has led to considerable therapeutic success in metastatic melanoma. To date, three checkpoint inhibitors have been approved for the treatment of metastatic melanoma. Ipilimumab is an antibody that binds cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4); Pembrolizumab and nivolumab cause immune stimulation by binding the Programmed Death Receptor (PD1). However, the impact of the therapy on the immune system as a whole is largely unknown. A comprehensive understanding of these effects is crucial to be able to further develop the therapy and to evaluate useful combination therapies with other immunomodulatory agents. Within the framework of this project changes of the immune response under a systemic therapy of the malignant melanoma are to be characterized. The material for the analysis comes from blood samples collected during routine patient check-ups. The aim of the analyzes is to precisely characterize the effects of the different therapeutics on the function of the immune system. In particular, the study will investigate whether certain therapeutic agents can weaken or activate the immune system and thus, in addition to the direct effect on the tumor cells, mediate indirect therapeutic effects via immune modulation. In the long term, the investigators want to use the knowledge gained to further improve the already existing therapeutic strategies of malignant melanoma by additional modulation of the immune system.
