Combination of Immunotherapy and Hyperthermia in Advanced Malignant Mesothelioma

Purpose:The purpose of this study is to investigate the clinical efficacy and toxicity of anti-PD-1 monoclonal antibody plus autologous dendritic cells-cytokine induced killer cell (DC-CIK) immunotherapy combined with hyperthermia in advanced malignant mesothelioma patients.Furthermore,to characterize response to therapy, we intent to explore the predictive biomarker for this regimen.

Phase 1 Study of CK-301 as a Single Agent in Subjects With Advanced Cancers

Purpose CK-301 is a fully human monoclonal antibody of IgG1 subtype that directly binds to Programmed Death-Ligand 1 (PD-L1) and blocks its interactions with the Programmed Death-1 (PD-1) and B7.1 receptors. The primary objective of this study is to assess the safety, tolerability and preliminary efficacy of CK-301 when administered intravenously as a single agent to subjects with selected recurrent or metastatic cancers.

Developing Optimal Parameters for Hyperpolarized Noble Gas and Inert Fluorinated Gas MRI of Lung Disorders

Purpose:The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.

Confocal Laser Endomicroscopy in Pleural Malignancies

Purpose:To date, the different biopsy methods, such as CT-guided pleural biopsy, mediastinal biopsy, endosonography and thoracoscopy have their limitations in diagnosing pleural malignancies, such as mesothelioma. Sampling errors frequently occur resulting in the common histological finding of ‘non-specific pleuritic/fibrosis’, which presents a great uncertainty for clinicians and patients. Confocal laser endomicroscopy (CLE) provides real-time imaging on a cellular level, however data of CLE in pleural malignancies are lacking.

CheckpOiNt Blockade For Inhibition of Relapsed Mesothelioma (CONFIRM)

Purpose:The UK has the highest incidence of mesothelioma. The incidence has risen by 497% since the late 1970’s and is increasing worldwide due to continued mining and use of asbestos. For patients with mesothelioma who have relapsed after taking pemetrexed and cisplatin, there is currently no standard treatment, making this an urgent unmet need. Recent trials in this area have not found an effective treatment that improves overall survival.

Following a debate in the House of Lords, a national survey assessing the research priorities in mesothelioma found that ‘exploiting the potential of immunotherapy’ was a top priority. This trial was designed in response to that survey. It uses the immunotherapy agent nivolumab which blocks programmed cell death 1 (PD-1) receptor on activated T-cells (a type of white blood cell forming part of the immune system). Early research has found a dependency of mesothelioma on the PD-1 checkpoint. By attaching to PD-1, nivolumab blocks its action (checkpoint inhibition), preventing it from turning off the T-cell, and therefore allowing the immune system to work. PD-1 checkpoint inhibition has revolutionised the treatment of melanoma and it is hoped to be as effective in mesothelioma.

This trial is a randomised, double blind placebo controlled trial of patients with mesothelioma who are third relapse following a platinum based chemotherapy treatment. Patients will be randomised in a 2:1 ratio (nivolumab: placebo).

336 patients will be recruited from 25 UK centres over a four-year period with the last patient having a minimum of 6 months follow up. All patients will be on treatment for 12 months unless they progress or withdrawal prior to this. Clinic visits will occur every 12 weeks, mirroring standard care. Data following progression will be obtained from the NHS Information Centre.
