PRODIGE 59-DURIGAST trial: A randomised phase II study evaluating FOLFIRI + Durvalumab ± Tremelimumab in second-line of patients with advanced gastri…
2021
International audience; Gastric or gastro-oesophageal junction (GEJ) adenocarcinomas present poor overall survival (OS). First-line chemotherapy regimen for patients with HER2-negative tumours is based on a doublet or triplet of fluoropyrimidine plus platinum salt ± taxane. Second-line chemotherapy (Docetaxel or Irinotecan) improves OS which nonetheless remains poor (around 5 months). The first results of immune checkpoint inhibitors (anti-PD-1) combined with chemotherapy in metastatic gastric and GEJ cancers were discordant in recent phase III trials. Data on dual-blockade (anti-PD-L1 or anti-PD-1 plus anti-CTLA-4) plus chemotherapy are lacking. DURIGAST is a randomised, multicenter, non-c…

Immune checkpoint inhibitors are widely used as treatment for an increasing number of solid tumours. Nevertheless, the lack of predictive biomarker represents a limitation across several cancer types. During the last years, the possibility to dynamically study tumour evolution through circulating tumour DNA (ctDNA) in plasma has opened novel possibility in evaluating disease status and therapeutic response, especially in localised disease to predict the possibility of relapse. However, the specific opportunities for application in the context of immunotherapy remain to be clarified.1 In an article recently published in Cancer Discovery by Zhang et al ,2 a comprehensive analysis of ctDNA dat…
Role of Immunotherapy in the Management of Hepatocellular Carcinoma: Current Standards and Future Directions
2020
The multikinase inhibitor sorafenib was the only approved systemic therapy in advanced hepatocellular carcinoma (HCC) for about a decade. In recent years, the number of approved agents has increased significantly as a result of a number of positive phase iii clinical trials. Lenvatinib as a first-line treatment, and regorafenib, cabozantinib, and ramucirumab in the second-line setting are now approved by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency. In phase II studies, immunotherapy with nivolumab and monotherapy using pembrolizumab yielded impressive results for overall survival in therapy-naïve and pretreated patients, leading to the accelerated approval …
Influence of the oncolytic parvovirus H-1, CTLA-4 antibody tremelimumab and cytostatic drugs on the human immune system in a human in vitro model of …

Bernd Heinrich,* Katrin Goepfert,* Maike Delic, Peter R Galle, Markus MoehlerUniversity Medical Center of the Johannes Gutenberg University Mainz, 1st Department of Internal Medicine, Langenbeckstrasse, Mainz, Germany *These authors contributed equally to this workIntroduction: Tumor-directed and immune-system-stimulating therapies are of special interest in cancer treatment. Here, we demonstrate the potential of parvovirus H-1 (H-1PV) to efficiently kill colorectal cancer cells and induce immunogenicity of colorectal tumors by inducing maturation of dendritic cells (DCs) alone and also in combination with cytostatic drugs in vitro. Using our cell culture model, we have additionally investi…
Phase Ib/II trial evaluating the safety, tolerability and immunological activity of durvalumab (MEDI4736) (anti-PD-L1) plus tremelimumab (anti-CTLA-4…

Background 5-Fluorouracil plus irinotecan or oxaliplatin alone or in association with target therapy are standard first-line therapy for metastatic colorectal cancer (mCRC). Checkpoint inhibitors targeting PD-1/PD-L1 demonstrated efficacy on mCRC with microsatellite instability but remain ineffective alone in microsatellite stable tumour. 5-Fluorouracil and oxaliplatin were known to present immunogenic properties. Durvalumab (D) is a human monoclonal antibody (mAb) that inhibits binding of programmed cell death ligand 1 (PD-L1) to its receptor. Tremelimumab (T) is a mAb directed against the cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). This study is designed to evaluate whether the …
Treatment of Hepatocellular Carcinoma with Immune Checkpoint Inhibitors and Applicability of First-Line Atezolizumab/Bevacizumab in a Real-Life Setti…
2021
Immune checkpoint inhibitors (ICIs) are the new frontier for the treatment of advanced hepatocellular carcinoma (HCC). Since the first trial with tremelimumab, a cytotoxic T-lymphocyte-associated protein 4 inhibitor, increasing evidence has confirmed that these drugs can significantly extend the survival of patients with advanced hepatocellular carcinoma (HCC). As a matter of fact, the overall survival and objective response rates reported in patients with advanced HCC treated with ICIs are the highest ever reported in the second-line setting and, most recently, the combination of the anti-programmed death ligand protein-1 atezolizumab with bevacizumab—an anti-vascular endothelial growth fa…
Facing the dawn of immunotherapy for hepatocellular carcinoma.

In this study, administration of tremelimumab was accompanied by a tolerable toxicity profile, most frequently including skin rash (65%), fatigue (55%), and anorexia (50%). During the initial course of tremilimumab, a transient increase of serum transaminase activity was observed. Hepatotoxicity did not impair liver function, even in the context of Child-Pugh B cirrhosis and hepatitis C. Therapy was stopped in 3 patients before tumor response evaluation was completed due to tremilimumab-related diarrhea or clinical deterioration, which was not associated with the treatment regimen. The relevance of this study is strengthened by the inclusion of HCC patients, showing hepatitis C associated c…
