Tumour immunology and immunotherapy

Thurnher, D. Klaver

P2Y11 – chemokine receptor crosstalk (BioRender, Copyright: Thurnher/Klaver)

The Tumour Immunology Unit examines the interaction between developing tumours, such as renal cell carcinoma, and the immune system. It is clear that a complex chemokine/chemokine receptor network orchestrates the multi-faceted interactions between growing tumour tumours and infiltrating immune cells. Our study of tumour-immune cell interactions in situ is complemented by studies of differentiating human macrophages in vitro. This provides a framework for a better understanding of the development of tumour-associated macrophages that fuel pathogenic inflammation. In this context, we also examine the human-specific G protein-coupled ATP receptor P2Y11, which regulates chemokine receptor expression in a highly selective manner. Finally, we examine macrophage activation by Bacillus Calmette-Guérin (BCG), the most efficient adjuvant therapy for high-risk, non-muscle-invasive bladder cancer (NMIBC). Our overriding goal is to translate our findings and knowledge into improved therapies and measures to minimise side effects.

Unveiling three distinct molecular clusters in urothelial carcinoma: a roadmap for clinical precision

Renate Pichler, Nils C. H. van Creij

Whole-transcriptome profiling has delivered the first comprehensive understanding of the molecular heterogeneity in urothelial cancer (UC). With the aim to introduce personalised medicine, previous studies have successfully divided UC into different molecular clusters with the aim of introducing personalised medicine. The consensus was clear: biological classes should be prioritised over clinical classes. This complexity has thus far hindered their integration into guideline recommendations and routine clinical practice. This is a result of the complexity of the data required for molecular classification, as well as the fact that most molecular classification schemes were developed and validated only in muscle-invasive bladder cancer. The aim of the current project is to establish a simple, unique, clinically applicable molecular classification scheme of urothelial cancer. This will be based on whole transcriptome and proteome data with clinical implications for prognosis and therapy. The result will be a broader clinical applicability to non-muscle invasive bladder cancer as well as to muscle-invasive bladder cancer. We assigned single-cell RNA sequencing data (scRNAseq), FFPE urothelial cancer samples and publicly available UC cell lines to the different UC clusters. This was achieved by comparing pharmacological, metabolic and biological characteristics. This provides a comprehensive understanding of the complex biology of UC through a multifaceted methodology. Our new insights will pave the way for the development of more effective therapies for each cluster within the context of personalised medicine in UC.

Personalised urothelial cancer therapy proposing novel cluster-specific therapeutic agents

Renate Pichler, Nils C. H. van Creij

In this follow-up project, we will test cluster-specific novel therapeutic targets (EGFR inhibitors, PARP inhibitors, MAPk inhibitors….) in vitro in different cell lines and ex vivo in cluster-specific UC organoids. The aim is to develop more efficient (combination) therapies, particularly for the more aggressive subtypes, and thereby improve the prognosis.

LifeBoost: Comprehensive, networked and holistic care improving the quality of life during immunotherapy through evidence-based integrative services

Renate Pichler, Bernhard Holzner, Jens Lehmann

The introduction of immunotherapy revolutionised the therapeutic landscape for many immunogenic tumour entities, including bladder cancer. The occurrence of immunotherapy-associated side effects leads to treatment pauses or discontinuation of therapy, which leads to a deterioration in quality of life and patient compliance. The aim of the LifeBoost project is to expand the concept of the Comprehensive Cancer Centre (CCC) to include an integrative and anthropocentric supportive care approach with the creation of multidisciplinary and multimodal, digital supportive services for patients undergoing immunotherapy. This supportive program includes the areas of nutrition, exercise, music education and psycho-oncology. The existing digital platform of the Austrian Cancer Aid supports the implementation of the project and enables a standardised recording of quality of life through PROMs, as well as a systematic content analysis. In summary, LifeBoost is characterised by the bundling of different expertise and the use of existing resources, creating valuable synergies. We actively involve patients to deliver personalised care that addresses their medical, emotional and social needs.

Adjuvant treatment selection in urothelial cancer after radical cystectomy based on circulating tumour cells (ATUC-CTC)

Felizian Lackner, Antonia Partl, Gerald Klinglmair, Renate Pichler

Radical cystectomy (RC) with pelvic lymph node dissection, is the standard treatment for muscle-invasive bladder cancer. However, nearly 50% of patients experience recurrence. The CheckMate 274 study states that “high-risk” patients (ypT2–T4a or nodal-positive [ypN+] in those treated with neoadjuvant chemotherapy [NAC]; pT3–T4a or pN+ in patients without NAC) should receive adjuvant nivolumab when tumour programmed death ligand 1 (PD-L1) expression level is ³ 1%. However, PD-L1 has limitations as a prognostic marker in the adjuvant setting, as shown by discordant disease-free survival data from both the CheckMate 274 and AMBASSADOR trial. Liquid biopsy may offer a more sensitive marker for the detection of micrometastases post-RC. The IMvigor010 study found that only 37% of “high-risk” patients were ctDNA positive and benefited from adjuvant immunotherapy with atezolizumab. Our study identifies circulating tumour cells (CTCs) as a biomarker to determine which MIBC patients will benefit most from adjuvant immunotherapy. This optimises treatment, reduces toxicities as well as healthcare costs.

Training the synergy between Bacillus Calmette-Guérin and immune checkpoint-blocking antibodies in bladder cancer

Renate Pichler, Martin Thurnher

Fifty years after the introduction of Bacillus Calmette-Guérin (BCG), a live attenuated strain of Mycobacterium bovis, it is clearly the most effective and successful adjuvant immunotherapy of non-muscle invasive bladder cancer (NMIBC). In this work we summarise that training the synergy between BCG and immune checkpoint-blocking antibodies empowers macrophages to achieve their full potential in the fight against bladder cancer. We believe that this training can be further improved at different levels. On the one hand, BCG can be made more effective, for instance through genetic engineering. On the other hand, Fc-engineering of immune checkpoint-blocking antibodies may enhance the training effect of tumour cell phagocytosis by pre-activated macrophages. As a consequence, physically conjugating immune checkpoint-blocking antibodies to BCG may be an attractive option and give the bladder cancer immunotherapy script a new twist( Fig.1 and 2)

Training macrophage functions synergistically by BCG and immune checkpoint-blocking antibodies is the key to enhancing antitumour immune response in bladder cancer. (A) BCG primes macrophages for increased cytokine production and supports the generation of functional antibodies. After an initial stimulus, such as BCG, trained immunity is defined as an enhanced innate immune response to various pathogens. In innate immune cells, especially in macrophages, microbial ligands that bind to pattern recognition receptors can cause long-lasting metabolic and epigenetic alterations. When the cell is stimulated again, transcription factors can more easily access the promoter and enhancer regions of pro-inflammatory genes thanks to this reprogramming of the metabolic and epigenetic landscape. This facilitates the expression of pro-inflammatory genes. When these metabolic and epigenetic effects are combined, the response to a secondary stimulation with the same or a different ligand is enhanced, increasing also anti-tumour immune response as BCG primes macrophages for increased cytokine production. BCG vaccination does two things. It trains the body’s natural defences, and it produces functional antibodies. These antibodies can also attack tumour cells. (B) Therapeutic IgG antibodies against PD-1 or PD-L1 are key to de-repressing macrophage phagocytosis and priming macrophages for increased FcR-dependent tumour cell phagocytosis. IgG antibodies support the restoration of tumour cell phagocytosis by tumour-associated macrophages. Therapeutic IgG antibodies can prime macrophages for enhanced phagocytosis of tumour cells. This increases the possibility that prior activation of FcR in TAMs by therapeutic checkpoint inhibition antibodies facilitates tumour cell killing mediated by anti-tumour antibodies elicited by BCG vaccination. This generates a synergistic effect between BCG and ICI. In the future, we will genetically engineer BCG and Fc-engineer IgG antibodies. This will give the bladder cancer immunotherapy script a new twist. Figure created with Biorender.com.

We implemented target trial emulation for causal inference and showed for the first time that there is no longer a significant association between the occurrence of irAEs (regardless of the administration of corticosteroids) and improved oncological outcomes and ICI response rates when adjusting the analysis to avoid immortal time bias. Target trial emulation is the statistical methodology that should be used to limit common bias in observational studies. This is because it conceptualises them as attempts to hypothetical randomised trials answering causal questions of interest. Our data underline the importance of carefully designing observational studies based on real-world data, applying principles of randomised controlled trials to observational studies by target trial emulation. These enhancements will provide readers with a clearer understanding of the TTE method, its advantages and its significance in our research. (Cancer Immunology Immunotherapy)

Tumour microenvironment in prostate cancer

Isabel Heidegger-Pircher, Mona Kafka, Nastasiia Artamonova, Felix Melchior

Our research group is firmly engaged in the molecular characterisation of the tumour microenvironment in prostate cancer. We recently conducted an in-depth analysis of this microenvironment for the first time using single-cell sequencing. We are currently investigating age-dependent differences in immune cell composition and tissue architecture in younger versus older patients. We are also conducting Spatial Transcriptomics in order to represent the spatial organisation and interaction of tumour and immune cells in tissue at the single-cell level. The bioinformatics analysis of these complex data is carried out in close collaboration with the Department of Bioinformatics (Z. Trajanoski).

Another project is focused on the diversity of neutrophil granulocytes in prostate cancer, a largely unexplored field. The goal is to functionally characterise different subpopulations of neutrophils in the tumour microenvironment. This project is currently being pursued as part of a doctoral thesis. We are also investigating possible disease-specific signatures and immunological peculiarities in collaboration with Internal Medicine V (D. Wolf).

We are examining the effects of intermittent fasting on tumour profiles and immune status in prostate cancer patients. Patients follow a standardised fasting protocol before planned prostatectomy or systemic therapy. Subsequently, multi-layered analyses are conducted. These include metabolomics, cytokine analysis and single-cell characterisation of peripheral immune cells. Initial results show that fasting modulates specific T-cell populations.

Active surveillance in prostate cancer

Isabel Heidegger-Pircher, Mona Kafka, Nastasiia Artamonova, Felix Melchior

Recently, we demonstrated for the first time that changes in collagen metabolism in prostate cancer are linked to a poor prognosis. Using mass spectrometry, we diagnosed collagen-associated genes in tissue, blood and urine. These can be used as biomarkers for 1) prostate cancer (yes/no), 2) biochemical recurrence (yes/no) after prostatectomy, and 3) as prognostic markers for poor survival. In an ongoing project, we are investigating the significance of the collagen score for unclear lesions in MRI in a multicentre study (Innsbruck as the lead centre) Our aim is to spare patients unnecessary biopsies and avoid overdiagnosis and overtreatment.

Neuroendocrine prostate cancer

Isabel Heidegger-Pircher, Mona Kafka, Nastasiia Artamonova, Felix Melchior

Neuroendocrine prostate cancer (NEPC) is a highly aggressive form of prostate cancer for which only one therapy (platinum-based chemotherapy) is currently available. Our long-term goal is to improve the care of NEPC patients. We will achieve this by understanding the molecular causes of therapy resistance and the development of NEPC, identifying new structures and concepts for therapeutic interventions, and optimising the diagnosis of emerging resistance. We are focusing on three specific areas: 1) the characterisation of the molecular mechanisms of therapy resistance in NEPC, 2) the development of blood-based biomarkers for the early detection of therapy resistance and NEPC features and 3) the development of new concepts for effective treatment of NEPC patients.

Personalised therapy of metastatic prostate cancer

Isabel Heidegger-Pircher, Mona Kafka, Nastasiia Artamonova, Felix Melchior

In the past three years, the therapeutic landscape of metastatic hormone-sensitive prostate cancer (mHSPC) has changed significantly. The introduction of combination therapies, particularly the so-called triplet therapy (androgen deprivation therapy + new hormonal therapy + docetaxel chemotherapy), has established new standards in the first-line therapy for patients with high-risk profiles. Our group was able to collect and analyse data from the world’s first multicentre real-world study on the clinical implementation of this triplet therapy in mHSPC. An update of this data analysis is currently being prepared. Our long-term research goal is to further personalise the treatment of mHSPC. Integrating molecular biomarkers is the key to improving individual risk assessment and enabling a patient-tailored therapeutic strategy.

Androgen receptor coactivators and novel targets in prostate cancer

Zoran Culig, Florian Handle, Chiara Andolfi, Martin Puhr

The research group investigated the role of a component of the MED complex, MED12. This component regulates the proliferation of androgen receptor-positive and androgen receptor-negative cancer cells. We studied how MED12 and cyclin-dependent kinase influence cellular processes in prostate cancer cells. Down-regulation of MED12 expression and CDK 8/19 activity reduced proliferation in cell lines and spheroids. We also observed a clear inhibition of the oncogene c-Myc in cancer cells. MED12 inhibition also down-regulated androgen receptor functional activity, in particular androgen receptor variant and prostate-specific antigen expression. We therefore conclude that MED12 and CDK8/19 regulate cellular processes in prostate cancer. This is a key factor in the development of malignancy and tumour progression. In collaboration with Profs. Taubert, Wach (Erlangen) and Aigner (Leipzig), we also found that miR-454-3p directly targets full-length and variant androgen receptors. The results of this project revealed new mechanisms of regulation of androgen receptor expression and activity.

The impact of glucocorticoid administration on prostate cancer progression and therapy resistance

Martin Puhr, Florian Handle, Isabel Heidegger, Zoran Culig, Andrea Eigentler

The glucocorticoid receptor (GR) is a key molecule in the development of therapy resistance in prostate cancer. As standard androgen receptor-directed therapies fail to block the GR and GR inhibitors and might result in unspecific side effects, the identification of GR signature genes is clinically important. We investigated the altered epithelial and stromal GR signature in prostate cancer cells after glucocorticoid treatment and identified monoamine oxidase (MAO-A) as a mutual directly up-regulated epithelial and stromal GR target. MAO-A is a mitochondrial membrane-bound oxidoreductase that catalyses the degradation of biogenic and xenobiotic amines. It is up-regulated during prostate cancer progression and after glucocorticoid receptor treatment. Glucocorticoid treatment caused altered GR-target gene expression and changes in the morphology of cancer-isolated fibroblasts. Glucocorticoid treatment influences prostate cancer cell growth and the tumour microenvironment via altered GR signalling in prostate fibroblasts.

Regulation of the AR splice variant V7 by small nucleotide variants

Frédéric R. Santer, Jasper van Goubergen

The androgen receptor splice variant V7 is a hallmark of castration-resistant prostate cancer. Lacking the ligand-binding domain, this cannot be targeted by endocrine treatments for prostate cancer. Therefore, it drives the progression of the disease. AR V7 mRNA has a different 3´untranslated region. This indicates that ARV7 is subject to different regulations at the post-transcriptional level. We characterised the allelic effects of small nucleotide polymorphisms with high minor allele frequency. AR V7 is used as a therapy-guiding biomarker. These quantitative expression trait loci (eQTL) will improve the specificity of this biomarker. The project generated data showing that targeting aberrant alternative splicing at the 3´UTR of ARV7 by disturbing the CLK2/SRSF9 axis could be a valuable approach in late stages prostate cancer.

Tumour microenvironment and novel targets in prostate cancer

 N. Sampson, E. Brunner, E. Damisch, L. Nommensen, M. Groeninger

The stromal tumour microenvironment (TME) is critical to the development, progression and response to the therapy of prostate cancer. Cancer-associated fibroblasts (CAFs) are the dominant cell type within the PCa TME, but display considerable heterogeneity at both the molecular and functional level. We are investigating the molecular and physical mechanisms underlying CAF plasticity and their clinical relevance on disease progression and therapy efficacy. Our aim is to identify new targets that will (i) enable the distinction between progressive vs. indolent disease and (ii) that can be exploited therapeutically in an adjuvant stromal-targeted approach. We are also investigating the role of NADPH oxidase 4 (NOX4), a ROS-producing enzyme expressed in a subpopulation of CAFs. We previously showed that this enzyme is a central mediator of a signalling hub at the tumour cell-CAF interface.

Drug repurposing in prostate cancer

Zoran Culig, Henrike Held, Martin Puhr

The development of new drugs for prostate cancer is expensive. A second strategy is based on computational analysis of drugs currently used for other diseases. A new project has been initiated. Its aim is to identify drugs that can target therapy-resistant prostate cancer.
