Research Highlights
In this edition of the JITC Digest, there are four noteworthy articles in the Clinical/Translational Cancer Immunotherapy section. The first article, “Effect of neoadjuvant chemotherapy on the immune microenvironment in non–small cell lung carcinomas as determined by multiplex immunofluorescence and image analysis approaches,” by Edwin R. Parra et al. provides a retrospective analysis of the immunological profile of non-small cell lung carcinoma (NSCLC) treated with neoadjuvant chemotherapy (NCT). Specifically, this study uses multiplex immunofluorescence and image analysis to demonstrate chemotherapy-induced changes in the tumor microenvironment of patients treated with NCT compared to those who underwent primary surgical resection without NCT. The results indicate that, contrary to previous thinking, chemotherapy may act ivate specific immune response mechanisms in NSCLC, priming a positive response to checkpoint immunotherapy.
In the article, “Inhibition of WEE1 kinase and cell cycle checkpoint activation sensitizes head and neck cancers to natural killer cell therapies,” Jay Friedman et al. describes how AZD1775, a small molecule inhibitor of WEE1 kinase, prevents G2/M cell cycle checkpoint activation and sensitizes tumor cells to granzyme B-dependent natural killer (NK) cell lysis using a newly characterized murine NK cell line. Additionally, concomitant treatment of adoptively transferred murine NK cells with WEE1 kinase inhibition in immunocompetent mice with aggressive tumors prolonged survival over either treatment alone. These results provide rationale for the combination of NK cell therapies and targeted therapies that block cell cycle checkpoint activation.
Next, the article, “Pan-cancer adaptive immune resistance as defined by the Tumor Inflammation Signature (TIS): results from The Cancer Genome Atlas (TCGA),” by Patrick Danaher et al. explores the TIS, an investigational use only, 18-gene signature shown to correlate with patients who respond to the PD1 inhibitor, pembrolizumab. The authors applied the TIS algorithm to over 9000 tumor gene expression profiles from the TCGA. They found that, similar to the tumor ranking determined by Spranger et al. (2016), tumors sensitive to PD-1 blockade had higher average TIS scores. Therefore, with an increased understanding of tumor immune profiles, they propose that integration of TIS scores may lead to improved indication selection for testing immunotherapeutics.
Finally, Alexander Shimabukuro-Vornhagen et al.’s article, ‘Cytokine release syndrome,” provides a comprehensive and timely review of the mechanisms underlying cytokine release syndrome pathophysiology, risk factors, clinical presentation, differential diagnoses, and prognostic factors. The immense progress experienced in the field of cancer immunotherapy bears the need for an enriched understanding of potential treatment-related toxicities in order to make immune oncology interventions safer and more effective.

Hypothesis
From the Authors
"Anti-cancer immunotherapy is facing its own checkpoint. The effectiveness of checkpoint inhibition therapy is restricted to a minority of cancers endowed with a pre-existing immune infiltrate. Several models have been proposed to explain primary or secondary immune resistance to therapy. Missing is a unifying theory that could frame each model within a `satellite view’ of cancer and serve as a navigational tool for the rational selection of mono- or combination-therapies applicable to apposite sub-populations of patients. Here, we propose a strategy to unify individual models into a single unifying `Theory of Everything.’"

"Hemophagocytic lymphohistiocytosis (HLH) and similar immune system hyperactivation syndromes can occur as potentially fatal immune related adverse events (irAEs) with PD-1, PD-L1 and CTLA-4 inhibitors, and CAR T cell and BiTe therapies. Diagnostic and therapeutic guidelines for malignancy- and immunotherapy-associated HLH are lacking, which complicates early diagnosis and management. The article describes cases of HLH, macrophage activation syndrome, and cytokine release syndrome due to various immunotherapeutic agents, and provides information regarding early recognition, diagnostic criteria and treatment approaches."

Research Article
From the Authors
"Immunosuppressive corticosteroids are first-line agents against immune-related adverse events arising from checkpoint blockade in patients with cancer. However, for patients with intracranial tumors, corticosteroids are often initiated at the time a brain tumor is discovered and continued during surgery and chemoradiation, a period that can span 8-12 weeks. Therefore, patients with intracranial tumors are likely to be exposed to corticosteroids before receiving immunotherapy. This study interrogated the impact of corticosteroids on adaptive anti-tumor immunity and confirmed that corticosteroids markedly impair the immune response if administered prior to immunotherapy. Conversely, corticosteroids do not diminish an established immune response. These results indicate that corticosteroid use should be avoided during the initiation of immunotherapy and that clinical trials should exclude patients requiring corticosteroids in order to increase the likelihood of response."

Case Report
About
Immune checkpoint inhibitors (ICI) have transformed the treatment arena and prognosis for lung cancer patients. However, with such immense progress in restoring a patient’s antitumor immune response comes related adverse events, such as sarcoidosis. Lea Paolini et al. report the first case of a thoracic and cutaneous sarcoid-like reaction in a patient with a relapsing, unresectable non-small cell lung cancer (NSCLC) treated with nivolumab, shedding light on the complex regulation of PD-1/PD-L1 expression and the importance of monitoring the immune response during and after treatment with ICI.

From the Authors
"Translational development of oncolytic vaccines, based on human-specific viruses, would be greatly enhanced by the availability of immunocompetent animal tumour modules that can study virus infection in the context of a functional immune system. We therefore consider it imperative to define the species-related blocks to virus activity in murine cancer cells, and to develop models that can be used to support the oncolytic activity of human-specific viruses."

“Pixatimod (PG545) is a clinical-stage immunomodulator currently under investigation with nivolumab in advanced and pancreatic cancers (Clinical Trial ID: ACTRN12617001573347). Though multiple preclinical studies have demonstrated additive or synergistic activity with chemotherapy, this is the first study to show the potential utility of pixatimod with a PD1 inhibitor. Importantly, the paper also explores the nonclinical and clinical exposure and safety data, with in-depth comparisons of key safety parameters across species. We hope that readers will gain a deeper understanding of pixatimod’s nonclinical and clinical safety profile, and its potential utility in combination with other I-O agents”

Review
Excerpt
“With growing experience in the clinical application of these potent immunotherapeutic agents comes the increasing awareness of their inherent and potentially fatal adverse effects, most notably the cytokine release syndrome (CRS). This review provides a comprehensive overview of the mechanisms underlying CRS pathophysiology, risk factors, clinical presentation, differential diagnoses, and prognostic factors.”

About
This open-label Phase Ia study assesses safety, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of the novel Indoleamine-2,3-dioxygenase 1 (IDO1) small molecule inhibitor, navoximod, in patients with recurrent/advanced solid tumors. As evidenced in the current study, data demonstrate that IDO inhibitors produce minimal antitumor activity when given alone. However, emerging clinical data from Phase I/II studies suggest the potential for increased benefit from a combination approach with IDO inhibitors and targeted immunotherapy drugs.

Commentary
From the Author
"A recent publication by Veglia et al. shows that oxidized lipids sequester the cytosolic chaperone HSP70, and that this contributes to reduced cross-presentation in dendritic cells from tumour-bearing mice. This commentary discusses these results in the context of the multiple roles of HSP70, lipid droplet function, and MHC-I trafficking, as well as their impact on future cancer therapy designs."

"While mechanisms of tumor cell immune escape based on the immunosuppressive tumor microenvironment are well studied, tumor cell intrinsic mechanisms of resistance to effector immune cell killing are less understood. The ability to reverse tumor G2/M cell cycle pause in response to granzyme B with a small molecule inhibitor of Wee1 kinase is an exciting finding that we hope translates into improved efficacy of a diverse array of immunotherapies in clinical trials."

Research Article
From the Authors
"The Tumor Inflammation Signature (TIS) is an 18 gene analytically validated signature which detects the presence of an adaptive immune response peripherally suppressed in the tumor microenvironment by measuring the expression of genes associated with cytotoxic cells, antigen presentation, and IFNγ activity. The TIS has previously been shown to enrich, in a tumor-type agnostic manner, for a population of patients who responds to immune checkpoint blockade. Since the TIS (reagents, instrumentation, algorithm and software) has been analytically developed as an IUO diagnostic assay, the test can be prospectively deployed for patient selection in clinical trials. In this paper we characterized the level of the TIS across a range of tumor gene expression data downloaded from the TCGA in order to understand the prevalence of the tumor “inflamed” phenotype within and between tumor types. In addition, we evaluate how TIS level correlates with other relevant variables such as mutation load, other gene expression signatures, and clinical outcomes in the absence of specific immune therapeutic intervention (i.e. prognosis). Finally, to screen for novel suppressive mechanisms, this study searched for biological pathways associated with low TIS scores."
