Baylor Opens New Immunotherapy Clinical Trial for Mesothelioma

The Baylor College of Medicine in Houston has opened its latest clinical trial for mesothelioma patients to study the effectiveness of a novel immunotherapy combination. The nonsurgical, single-center study is looking for a dozen patients whose pleural mesothelioma has progressed after at least one regimen of chemotherapy. The phase II clinical trial involves Opdivo (nivolumab) and MTG201, a modified adenovirus designed to increase the efficacy of certain types of immunotherapy drugs. The combination was especially effective in preclinical mouse models. “We’re excited about the prospects of this combination,” thoracic surgeon and principal investigator Dr. Bryan Burt told The Mesothelioma Center at Asbestos.com. “You don’t know what the results will be until you try it, but in preclinical studies, there was a very striking response.” The impressive preclinical data is expected to be published later this summer. Burt is part of the Mesothelioma Treatment Program and the Dan L. Duncan Comprehensive Cancer Center at Baylor. He worked alongside legendary mesothelioma specialist Dr. David Sugarbaker, who helped build the Lung Institute before his death in 2018. As a surgeon, Burt understands the lack of effective treatment options available today for patients not eligible for surgery. “I don’t think anyone would argue that the survival benefits, the benefit of systemic therapy for mesothelioma patients, is suboptimal,” Burt sai...

Pioneering pulmonologists Dr. Steven Albelda and Dr. Daniel Sterman have worked for more than 20 years on developing gene therapy to effectively combat pleural mesothelioma cancer. The payoff may have finally arrived. Albelda and Sterman’s long-awaited, phase III clinical trial will open this month to evaluate the efficacy of TR002, a novel gene therapy drug, when used in combination with celecoxib and gemcitabine. TR002, a form of immunotherapy, is a genetically engineered adenovirus that triggers the anti-tumor effects of interferon, a naturally occurring protein that destroys cancer cells. “The hope is, if i...

Conclusions: Overall our data identify virotherapy, based on the use of dl922-947, as a new possible therapeutic strategy against MPM, which could be used alone, in combination with standard chemotherapy drugs, as shown here, or other approaches also aimed at enhancing the antitumoral immune response elicited by the virus.

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

A long-awaited phase III clinical trial of a novel gene therapy could change malignant pleural mesothelioma treatment in the future. The trial, which will include almost 50 locations around the world, opens this month for mesothelioma patients whose standard treatment has stopped working. The gene therapy drug, called TR002, is also a form of immunotherapy. It will be used in combination with gemcitabine chemotherapy in a second-line setting. “We can’t predict what the outcome will be, but we’re very excited about the potential of this treatment, and the fact there may be another drug in the armamentarium...

Oncologists in Spain are recruiting patients for the randomized phase of the pleural mesothelioma clinical trial involving ONCOS-102, the promising immunotherapy vaccine. Optimism surrounding the trial stems from encouraging results obtained recently in the six-patient safety cohort used as a precautionary lead-in. The trial involves the vaccine in combination with standard-of-care chemotherapy for patients with inoperable disease. ONCOS-102 is a scientifically engineered adenovirus that is designed to activate a patient’s immune system to selectively target cancer cells. It is being developed by Targovax, a Scandina...

Authors: Cappuccini F, Pollock E, Stribbling S, Hill AVS, Redchenko I Abstract The tumour-associated antigen 5T4 is an attractive target for cancer immunotherapy. However to date, reported 5T4-specific cellular immune responses induced by various immunisation platforms have been largely weak or non-existent. In the present study, we have evaluated a heterologous prime boost regime based on the simian adenovirus ChAdOx1 and modified vaccinia virus Ankara (MVA) expressing 5T4 for immunogenicity and tumour protective efficacy in a mouse cancer model. Vaccination-induced immune responses were strong, durable and attrib...

In this study, we investigated the effectiveness of the intrapleural instillation of a replication‐competent adenovirus as an oncolytic agent against MPM. We constructed a vascular endothelial growth factor promoter‐based conditionally replicative adenovirus (VEGF‐CRAd) that replicates exclusively in VEGF‐expressing cells. All of the MM cell lines that we tested expressed VEGF mRNA, and VEGF‐CRAd selectively replicated in these MM cells and exerted a direct concentration‐dependent oncolytic effect in vitro. Furthermore, our in vivo studies showed that pre‐infection of MM cells with VEGF‐CRAd potently suppre...

Scandinavian-based Targovax launched the latest immunotherapy clinical trial for pleural mesothelioma, hoping it delivers a better way to treat patients with asbestos-related diseases. The randomized phase Ib/II trial evaluates the performance of ONCOS-102, an engineered human adenovirus designed to induce systemic, anti-tumor responses. Researchers are administering the immunotherapy drug as first-line therapy in combination with chemotherapy using pemetrexed and cisplatin. “Based on what we’ve seen in our first study of patients with various solid tumor types, which is good tolerance and response in a couple ...

Malignant mesothelioma (MM) is a rare cancer type caused mainly by asbestos exposure. The median overall survival time of a mesothelioma cancer patient is less than 1‐year from diagnosis. Currently there are no curative treatment modalities for malignant mesothelioma, however treatments such as surgery, chemotherapy and radiotherapy can help to improve patient prognosis and increase life expectancy. Pemetrexed‐Cisplatin is the only standard of care (SoC) chemotherapy for malignant mesothelioma, but the median PFS/OS (progression‐free survival/overall survival) from the initiation of treatment is only up to 12 months....
