In the last three decades huge efforts have been made to characterize genetic defects responsible for cancer development and progression, leading to the comprehensive identification of distinct cellular pathways affected by the alteration of specific genes. Despite the undoubtable role of genetic mechanisms in triggering neoplastic cell transformation,(More)
BACKGROUND The combination of cobimetinib with vemurafenib improves progression-free survival compared with placebo and vemurafenib in previously untreated patients with BRAF(V600)-mutant advanced melanoma, as previously reported in the coBRIM study. In this Article, we report updated efficacy results, including overall survival and safety after longer(More)
BACKGROUND Monoclonal antibodies to cytotoxic T-lymphocyte antigen 4 (CTLA4) have therapeutic activity in different tumour types. We aimed to investigate the efficacy, safety, and immunological activity of the anti-CTLA4 monoclonal antibody, tremelimumab, in advanced malignant mesothelioma. METHODS In our open-label, single-arm, phase 2 study, we enrolled(More)
The promising new class of immunomodulating antibodies directed against cytotoxic T-lymphocyte antigen-4 (CTLA-4) has been extensively tested in clinical trials and found to be active against cutaneous melanoma and other tumor histotypes. Inhibition of CTLA-4 characteristically induces well-identified side effects for which the definition "immune-related(More)
BACKGROUND Ipilimumab improves survival of patients with metastatic melanoma, many of whom develop brain metastases. Chemotherapy-induced release of tumour antigens might amplify ipilimumab's antitumour activity. We aimed to investigate the efficacy and safety of ipilimumab plus fotemustine in patients with metastatic melanoma with or without asymptomatic(More)
PURPOSE To identify baseline peripheral blood biomarkers associated with clinical outcome following ipilimumab treatment in advanced melanoma patients. EXPERIMENTAL DESIGN Frequencies of myeloid-derived suppressor cells (MDSC) and regulatory T cells (Treg), serum lactate dehydrogenase (LDH), routine blood counts, and clinical characteristics were assessed(More)
BACKGROUND CTLA4 blockade by tremelimumab 15 mg/kg every 90 days provided preliminary evidence of activity in patients with pretreated malignant mesothelioma; however, retrospective exposure-response analysis of data from patients with melanoma suggested that this schedule could result in underexposure to tremelimumab. We therefore investigated the efficacy(More)
Background:Ipilimumab improves the survival of metastatic melanoma patients. Despite documented, durable objective responses, a significant number of patients fails to benefit from treatment. The aim of this study was to identify an upfront marker for treatment benefit.Methods:A total of 187 metastatic melanoma patients treated in three Italian Institutions(More)
Emerging in vitro evidence points to an immunomodulatory activity of DNA hypomethylating drugs in human malignancies. We investigated the potential of 5-aza-2'-deoxycytidine (5-AZA-CdR) to modulate the expression of cancer testis antigens (CTA) and of HLA class I antigens by melanoma xenografts, and the resulting modifications in immunogenicity of(More)
Epigenetic alterations play a pivotal role in cancer development and progression. Pharmacologic reversion of such alterations is feasible, and second generation "epigenetic drugs" are in development and have been demonstrated to possess significant immunomodulatory properties. This knowledge, together with the availability of new and highly effective(More)
