A shared tumor-antigen RNA-lipoplex vaccine with/without anti-PD1 in patients with checkpoint-inhibition experienced melanoma.
2020
3136 Background: Cancer vaccines are considered unsuitable for patients with advanced tumours and have not been clinically successful. Methods: Lipo-MERIT is an ongoing phase 1/2 trial (NCT02410733) with melanoma FixVac, a liposomal RNA vaccine targeting four non-mutant shared tumour-associated antigens (TAAs) (MAGE-A3, NY-ESO-1, tyrosinase, TPTE). Patients with stage IIIB-C and IV melanoma are eligible. The trial comprises 7 dose escalation and 3 dose expansion cohorts, the latter with FixVac alone or combined with anti-PD1. Eight doses of FixVac are administered i.v. weekly/bi-weekly followed by optional continued monthly treatment. This abstract summarizes the findings of an exploratory…
Immune checkpoint inhibitors-associated pericardial disease: a systematic review of case reports
2021
Treatment with immune checkpoint inhibitors (ICIs) can be complicated by cardiovascular toxicity, including pericardial disease. To date, no prospective studies specifically investigated the optimal treatment of ICI-associated pericardial disease, and the available evidence is based on case reports and series only. We performed a systematic review of case reports and series including 20 publications for a total of 28 cases of ICI-associated pericardial disease. In this review, pericardial disease was reversible in the majority of cases (75%), although 2 deaths were reported. The majority of cases were life-threatening (G4, 53.6%) or severe (G3, 21.4%), requiring pericardiocentesis. Higher r…
Novel Approaches for Glioblastoma Treatment: Focus on Tumor Heterogeneity, Treatment Resistance, and Computational Tools
2019
BACKGROUND: Glioblastoma (GBM) is a highly aggressive primary brain tumor. Currently, the suggested line of action is the surgical resection followed by radiotherapy and treatment with the adjuvant temozolomide (TMZ), a DNA alkylating agent. However, the ability of tumor cells to deeply infiltrate the surrounding tissue makes complete resection quite impossible, and in consequence, the probability of tumor recurrence is high, and the prognosis is not positive. GBM is highly heterogeneous and adapts to treatment in most individuals. Nevertheless, these mechanisms of adaption are unknown. RECENT FINDINGS: In this review, we will discuss the recent discoveries in molecular and cellular heterog…
Immunotherapy With Human Gamma Delta T Cells—Synergistic Potential of Epigenetic Drugs?
2018
Epigenetics has emerged as one of the fastest growing concepts, adding more than 45 new publications every day, spreading through various fields ( 1). Conrad Waddington coined the term “epigenetics” in 1942; however, a multitude of definitions has been endorsed by different researchers. In essence, Waddington’s definition of “epigenetics” and its redefinition by Holiday is at the heart of cellular function. Hence, it is obvious that epigenetic regulation plays a central role also in the specification, differentiation, and functional plasticity of T lymphocytes ( 2). T-cell fate decision in progenitor cells, functional CD4 T-cell plasticity, CD8 T-cell differentiation, but also T-cell memory…
Immunotherapy in gastrointestinal cancer: Recent results, current studies and future perspectives
2016
The new therapeutic approach of using immune checkpoint inhibitors as anticancer agents is a landmark innovation. Early studies suggest that immune checkpoint inhibition might also be effective in patients with gastrointestinal cancer. To improve the efficacy of immunotherapy, different strategies are currently under evaluation. This review summarises the discussion during the European Organisation for Research and Treatment of Cancer Gastrointestinal Tract Cancer Translational Research Meeting in Mainz in November 2014 and provides an update on the most recent results of immune therapy in gastrointestinal cancers. Knowledge of potential relationships between tumour cells and their microenv…
First-Line Immune Checkpoint Inhibitor-Based Sequential Therapies for Advanced Hepatocellular Carcinoma: Rationale for Future Trials
2021
<b><i>Introduction:</i></b> Atezolizumab (ATEZO) plus bevacizumab (BEVA) represents the new standard of care for the treatment of advanced hepatocellular carcinoma (HCC). However, the choice of the second-line treatment after the failure of immunotherapy-based first-line remains elusive. Taking into account the weaknesses of the available evidence, we developed a simulation model based on available phase III randomized clinical trials (RCTs) to identify optimal risk/benefit sequential strategies. <b><i>Methods:</i></b> A Markov model was built to estimate the overall survival (OS) of sequential first- and second-line systemic treatments. Seque…
Optimizing systemic therapy for advanced hepatocellular carcinoma: the key role of liver function
2022
The number of effective systemic therapies for the treatment of advanced hepatocellular carcinoma (HCC) is rapidly increasing, and the advent of immunotherapy has changed the treatment paradigm for these patients, leading to significantly improved survival outcomes. However, many patients with HCC will continue to receive tyrosine kinase inhibitors, partly because of contraindications to immune checkpoint inhibitors. Currently, the best sequential first- and second-line systemic treatment remains elusive. Maintenance of optimal liver function is crucial, it is likely to impinge on temporary or permanent treatment discontinuation, and should also be considered when defining the treatment seq…
Pretreatment metastatic growth rate determines clinical outcome of advanced melanoma patients treated with anti-PD-1 antibodies: a multicenter cohort…
2021
BackgroundCheckpoint inhibitors revolutionized the treatment of metastatic melanoma patients. Although tumor burden and lactate dehydrogenase (LDH) are associated with overall survival (OS), the impact of tumor growth kinetics remains elusive and in part contradictory. The aims of this study were to develop a novel simple and rapid method that estimates pretreatment metastatic growth rate (MGR) and to investigate its prognostic impact in melanoma patients treated with antiprogrammed death receptor-1 (PD-1) antibodies.MethodsMGR was assessed in three independent cohorts of a total of 337 unselected consecutive metastasized stage IIIB–IV melanoma patients (discovery cohort: n=53, confirmation…
INfluenza Vaccine Indication during therapy with Immune checkpoint inhibitors: A multicenter prospective observational study (INVIDIa-2)
2021
BackgroundUntil now, no robust data supported the efficacy, safety and recommendation for influenza vaccination in patients with cancer receiving immune checkpoint inhibitors (ICIs).MethodsThe prospective multicenter observational INfluenza Vaccine Indication During therapy with Immune checkpoint inhibitors (INVIDIa-2) study investigated the clinical effectiveness of influenza vaccination in patients with advanced cancer receiving ICIs, enrolled in 82 Italian centers from October 2019 to January 2020. The primary endpoint was the time-adjusted incidence of influenza-like illness (ILI) until April 30, 2020. Secondary endpoints regarded ILI severity and vaccine safety.ResultsThe study enrolle…
First-line nivolumab plus chemotherapy versus chemotherapy alone for advanced gastric, gastro-oesophageal junction, and oesophageal adenocarcinoma (C…
2021
First-line chemotherapy for advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastro-oesophageal junction adenocarcinoma has a median overall survival (OS) of less than 1 year. We aimed to evaluate first-line programmed cell death (PD)-1 inhibitor-based therapies in gastric, gastro-oesophageal junction, and oesophageal adenocarcinoma. We report the first results for nivolumab plus chemotherapy versus chemotherapy alone.In this multicentre, randomised, open-label, phase 3 trial (CheckMate 649), we enrolled adults (≥18 years) with previously untreated, unresectable, non-HER2-positive gastric, gastro-oesophageal junction, or oesophageal adenocarcinoma, …
