Immune checkpoint inhibitors (ICI) have become a key component of therapy for several solid tumours. In patients diagnosed with advanced clear cell renal cell carcinoma (ccRCC), immunotherapy has always been considered as a treatment option, and anti-PD-1-based therapies are approved in both the frontline and refractory settings. Response to PD-1 blockade has been associated with numerous tumour-intrinsic and microenvironment features. Genetic characterisation of ccRCC has significantly contributed to the knowledge of tumour biology and the mechanisms of disease progression, but the interplay of genomic alterations with patterns of immune infiltration in response to PD-1 blockade remains un…
7 Evolution of cross-resistance to CD8+ T cells in the course of BRAF and MEK inhibitor treatment in BRAFV600E melanoma
2018
Introduction The BRAFV600 mutation, expressed in approximately 50% of melanomas, mediates constitutive activation of the BRAF-MEK-ERK in the MAPK signalling pathway and therefore tumour proliferation. Rapid and high rate of clinical responses can be achieved by targeting this axis using BRAF V600 inhibitor (BRAFi) as single therapy or the combination of BRAFi and MEKi (BRAFi/MEKi). But still disease progresses in the majority of treated patients due to acquired resistance in tumour cells. Combining targeted therapy with immunotherapy is proposed to improve the long-term outcomes of patients. However, to which extent BRAFi may affect melanoma immunogenicity over time remains largely unknown.…
Immunological aspects of heat shock protein functions and their significance in the development of cancer vaccines
2022
The primary function of intracellular heat shock proteins (HSPs) is to protect the cell by suppressing the effects of various stress factors by either refolding misfolded proteins or blocking apoptosis. After neoplastic transformation, cells overexpress HSPs, which act as factors promoting the neoplastic process by stabilizing proteins responsible for carcinogenesis, however, HSPs can be released into the extracellular environment where they act as important modulators of the immune response. In a tumor microenvironment, extracellular HSPs are able to induce a pro- or anti-neoplastic response, using various mechanisms of affecting immune cells, The study of the role of extracellular HSPs in…
The Role of Immune Checkpoint Blockade in the Hepatocellular Carcinoma: A Review of Clinical Trials.
2021
The prevalence of primary liver cancer is rapidly rising all around the world. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Unfortunately, the traditional treatment methods to cure HCC showed poor efficacy in patients who are not candidates for liver transplantation. Until recently, tyrosine kinase inhibitors (TKIs) were the front-line treatment for unresectable liver cancer. However, rapidly emerging new data has drastically changed the landscape of HCC treatment. The combination treatment of atezolizumab plus bevacizumab (immunotherapy plus anti-VEGF) was shown to provide superior outcomes and has become the new standard first-line treatment for unresect…
Exploring the Dynamic Crosstalk between the Immune System and Genetics in Gastrointestinal Stromal Tumors
2022
Gastrointestinal Stromal Tumors (GISTs) represent a paradigmatic model of oncogene addiction. Despite the well-known impact of the mutational status on clinical outcomes, we need to expand our knowledge to other factors that influence behavior heterogeneity in GIST patients. A growing body of studies has revealed that the tumor microenvironment (TME), mostly populated by tumor-associated macrophages (TAMs) and lymphocytes (TILs), and stromal differentiation (SD) have a significant impact on prognosis and response to treatment. Interestingly, even though the current knowledge of the role of immune response in this setting is still limited, recent pre-clinical and clinical data have highlight…
Soluble biomarker signature to predict outcome of patients with non-small-cell lung cancer (NSCLC) treated with anti-PD1/PDL1 monoclonal antibodies.
2019
e20685 Background: Immunotherapy with anti-PD1/PDL1 monoclonal antibodies has become the second line standard treatment for most patients diagnosed of advanced Non-Small-Cell lung cancer (NSCLC). The aim of this study is to assess the utility of circulating biomarkers such as sPDL1, sPDL2, sCD137, sIDO, sTIM3, sCD28, sCD27, sCTLA4, sHVEM, sLAG3, sCD80 and sGITR for predicting efficacy of immunotherapy with anti-PD1/PDL1 therapies. Methods: Blood samples were collected before treatment from 50 NSCLC patients who received anti PD1/PDL1 therapies (second line). Plasma biomarkers´ levels were measured by Multiplex bead-based assays. Continuous variables were categorized using the median as a c…
Overall survival at 5 years of follow-up in a phase III trial comparing ipilimumab 10 mg/kg with 3 mg/kg in patients with advanced melanoma
2020
BackgroundWe have previously reported significantly longer overall survival (OS) with ipilimumab 10 mg/kg versus ipilimumab 3 mg/kg in patients with advanced melanoma, with higher incidences of adverse events (AEs) at 10 mg/kg. This follow-up analysis reports a 5-year update of OS and safety.MethodsThis randomized, multicenter, double-blind, phase III trial included patients with untreated or previously treated unresectable stage III or IV melanoma. Patients were randomly assigned (1:1) to ipilimumab 10 mg/kg or 3 mg/kg every 3 weeks for 4 doses. The primary end point was OS.ResultsAt a minimum follow-up of 61 months, median OS was 15.7 months (95% CI 11.6 to 17.8) at 10 mg/kg and 11.5 mont…
A randomized, double-blinded, placebo-controlled multicenter phase II trial of adjuvant immunotherapy with tecemotide (L-BLP25) after R0/R1 hepatic c…
2019
480 Background: Hepatic metastasectomy is the only potential curative treatment option for stage IV colorectal cancer (CRC) limited to liver metastases (LM). After R0 resection of LM the high recurrence rate remains a major challenge. L-BLP25 is an antigen-specific cancer vaccine targeting mucin 1 (MUC1). The LICC trial aimed to improve survival outcome in mCRC patients (pts) after R0/R1 LM resection. Methods: This LICC trial, a binational, multicenter, double-blinded, placebo controlled phase II trial, included pts with stage IV LM limited CRC after resection of primary tumor and LM (R0/R1) within the last 8 weeks, ECOG 0/1 and adequate organ function. Pts were 2:1 randomized to receive L…
ABCL-366: Mosunetuzumab (Mosun) Monotherapy for Elderly/Unfit Patients with First-Line Diffuse Large B-Cell Lymphoma (DLBCL) Continues to Show Promis…
2021
Context Mosun, a full-length, humanized, IgG1 CD20×CD3 bispecific antibody, demonstrated efficacy/safety in relapsed/refractory DLBCL (NCT02500407; Schuster, et al. ASH 2019). The phase I/II multicenter GO40554 (NCT03677154) study showed similar results for elderly/unfit patients with first-line DLBCL intolerant of full-dose chemoimmunotherapy (CIT) (Olszewski, et al. ASH 2020). Objective To describe updated GO40554 study data. Methods Two safety-evaluation cohorts were assessed (Mosun 13.5 mg and 30 mg), then a 30 mg expansion phase. Patients were aged ≥80 years; 60–79 years with impairment in ≥1 activity of daily living (ADL); instrumental ADL; or impaired cardiac, renal, or liver functio…
Recent Advances in the Treatment of Patients with Multiple Myeloma
2020
Simple Summary The evolving data from trials assessing novel combinations as a part of the frontline and relapse treatment in transplant and non-transplant candidates have markedly improved the anti-myeloma efficacy of the different therapeutic regimens and improved patients’ prognosis. Current treatment objectives are focused to further improve the rate of complete remission, time to progression, progression-free survival and overall survival without increasing toxicity. Besides, different strategies are being developed in the elderly population as this group of patients requires a closer monitoring with individualized, dose-modified regimens to improve tolerability while maintaining their…
