Directors comments The K.G. Jebsen Center for Cancer Immunotherapy (JCIT) opened in June 2013, and the present report will thus cover highlights from the first (close to) 2 years in the life of JCIT. The formation of the center allowed six partnering groups at the University of Oslo/ Oslo University hospital and the Netherlands Cancer Institute to join forces to develop new strategies in cancer immunotherapy, and the first period has been very active.

Immunotherapy was long regarded safe, but ineffective. However, in 2013, Science highlighted “Cancer Immunotherapy” as one of the breakthrough areas of the year. This was mainly due to the undisputable clinical success of therapeutic strategies releasing the power of T cells, including genetically engineered T cells and antibodies blocking checkpoint molecules. The timing for the formation of a Norwegian center focused on cancer immunotherapy was therefore excellent. The expertise of the six consortium PIs; Arne Kolstad, Fridtjof Lund-Johansen, Karl-Johan Malmberg, Johanna Olweus, Kjetil Taskén and Ton Schumacher, and their groups spans from basic immunology to clinical oncology, as reflected in a translational and interdisciplinary research program. Although the center has only been operational for two years, the synergies of coming together to address key bottlenecks in the field are already obvious.

The organization into a center has inspired a large number of new collaborative projects between the partners. The physical

proximity of the Oslo partners facilitates close interactions, while multiple exchange visits occur between Oslo-Amsterdam.

In particular, the center partners have given each other access to, and created patent-pending, frontline technologies that give the projects a highly competitive edge. A number of co-publications between partners have already emerged - many in high-impact journals - and several studies are near completion. Our international partner can also show to a commercial success story; the acquisition by Kite Pharmaceuticals of the T-Cell Factory B.V, founded by Ton Schumacher and colleagues, strengthening its TCR gene therapy platform.

The overarching goal of all our activities is to develop new and more effective therapies for patients with refractory cancer. A major accomplishment in 2014 was thus the completion of the LYMVAC clinical trial. A novel experimental immunotherapy protocol was administered to patients with follicular lymphoma, an incurable cancer by standard treatment. The intra-tumoral therapy resulted in clinical responses in 36% of the patients. For the first time, a reduction in tumor volume was demonstrated to correlate with vaccination-induced T-cell mediated anti-tumor reactivity. A new clinical trial – LYMVAC-2 – will start in 2015. Promising results have also been achieved in another ongoing phase I/II clinical trial, based on

vision:

To create novel immunotherapeutic strategies that overcome immunological tolerance to cancer

Johanna Olweus the adoptive transfer of haploidentical NK cells to patients with high-risk hematological malignancies (MDS and AML) who have no other treatment options. These clinical results and plans represent a major inspiration. The in-house technological platform, combined with longitudinal sampling of the treated patients, allow us to penetrate the mechanisms even deeper, paving the way for new and improved immunotherapy strategies.

In 2014, we organized an international Cancer Immunotherapy Symposium; “Harnessing innate and adaptive immunity in cancer therapy” for 150 delegates at Holmenkollen Park Hotel. The symposium was a success, and attracted a number of top international speakers, including Carl June, Martin

mid- t er m r e p o r t 2015

Pule, Jeff Miller and Rolf Kiessling, as well as “our own” Ton Schumacher. And Oslo showed itself from the sunny side. The meeting not only inspired our own center members, but also represents an example on the many positive effects that the center formation has on the general research community. Among important internal activities, I would like to emphasize that the center got valuable input from our Scientific Advisory Board, including the internationally leading scientists Fred Falkenburg, Rolf Kiessling and Hans Stauss, during the SAB meeting in November 2014. Moreover, our sense of a common direction and purpose has been further enforced during our retreats, the last one at Geilo in April, combining scientific discussions and presentations with fun in the snow.

We are very grateful for this opportunity given to us by the K.G. Jebsen Foundation, and by the University of Oslo (UiO). UiO represents the hosting institution for JCIT, which in partnership with Oslo University Hospital and the Netherlands Cancer Institute provide an excellent framework and infrastructure to facilitate our activities. We are confident that we are well positioned to bring even more exciting results to the benefit of cancer patients during the coming two years.

Approach 1. Use allo-reactivity to overcome self-tolerance We use novel strategies to discover T-cell epitopes from cell type-specific antigens and identify high-affinity T-cell receptors (TCRs) that recognize these in context of foreign HLA. The aim is to utilize cell-type specific TCRs to re-direct patient-derived T cells that are infused into the patient to target cancer cells. Another cell type that is triggered upon transfer across HLA barriers is RR the natural killer (NK) cell. Here we exploit insights into R the molecular specificity of NK cells in the design of cell therapy trials against refractory leukemia.

Approach 2. Identify and target cancer-specific neo-antigens Mutated antigens in cancer are foreign to the immune system and therefore potentially immunogenic. By identifying neo-antigen specific T-cell receptors, we plan to endow patient-derived T cells with the ability to specifically target the malignant cells.

Approach 3. Enhance effector T-cell function by overcoming inhibitory mechanisms The activity of T cells with the ability to recognize the tumor will be enhanced in three different ways: i) Modulation of the suppression mediated by so-called regulatory T cells (Tregs) ii) Reversing the effect of the inhibitory inflammatory mediator PGE2, which we have shown inhibits tumor growth and anti-tumor immune function in vivo, iii) Selection of effector T cells based on expression profiles of inhibitory receptors.

Kolstad group Our primary focus is to conduct clinical studies with novel immunotherapies and translational research in lymphoma.

Scientific summary The primary scientific focus of the Kolstad group is to conduct clinical studies with novel immunotherapies and translational research in lymphoma.

Kolstad has been involved in many studies in malignant lymphoma at Oslo University Hospital (OUS). He is leader of Focus Area Cancer Immunotherapy awarded by OUS in 2014. The main objective of this consortium is to facilitate translation of novel preclinical concepts into early exploratory clinical studies. A major goal for Kolstad within the K.G Jebsen Center (WP 6) has been to conduct and complete an early exploratory study with a novel in-house in situ vaccine strategy in a cohort of patients with stage III/IV incurable follicular non-Hodgkin`s lymphoma (Lymvac-I study). This work has been in collaboration between the Lymphoma group at OUS with Kolstad as principal investigator, and the group of Johanna Olweus, and results were recently published in Blood.

Further work within the JCIT consortium between Kolstad and the groups of Olweus and Schumacher has now been initiated to dissect tumor-specific mutations and potential epitopes targeted by tumor-reactive T cells in peripheral blood from clinical responders in the vaccine trial.

Based on the platform used for intranodal immunotherapy in the Lymvac-1 trial, the

aim of the follow-up study (Lymvac-2) is to enhance anti-tumor T-cell responses and corresponding clinical responses by adding the check-point inhibitor pembrolizumab (anti-PD-1). The company Merck will provide pembrolizumab for a study on 20 patients with follicular lymphoma over a period of 2-3 years. In-depth monitoring of anti-tumor T-cell responses will be performed by the Olweus group, as for Lymvac-1, and identification of neo-antigens as described above will be done in collaboration with Schumacher. In preparation of another study with CD20 peptide/HLA-A2-restricted T-cell receptors in lymphoma, preclinical work by the Olweus group with characterization and optimization of TCRs for GMP production in clinical trials is ongoing.

KEY ACHIEVEMENTS • The Lymvac-1 cancer vaccine study for patients with stage III/IV incurable follicular lymphoma was conducted within the KG Jebsen Center for Cancer Immuntherapy as a collaboration with the Immunology group of Olweus at the Institute of Cancer Research. Kolstad invented the strategy, wrote the protocol and was PI for this early exploratory single institution study.

Of 14 patients treated, 5 showed objective responses (36%) of which 2 had durable complete responses. Responding patients had strong CD8 T cell activity against autologous tumor cells in peripheral blood.

Lund-Johansen group Our main focus is to build large scale assays for detection or autoantibodies in serum.

Scientific summary Our main focus is to build large scale assays for detection or auto-antibodies in serum.

Microsphere-based arrays with content of full-length human proteins open for high throughput screening of auto-antibodies in serum from cancer patients. The assays will allow near genome-wide screening of self-proteins that are recognized as foreign by the humoral immune system. The information is used to identify candidate targets for immunotherapy and to monitor effects of the treatment.

The focus of the Lund-Johansen group is development of array-based proteomics. Microsphere affinity proteomics (MAP) is based on the use of bead-based arrays and flow cytometry. The technology was invented by FLJ, and the throughput is 200 times higher than mass spectrometry (MS). Our main effort within the context of JCIT is production of MAP protein arrays. These will be used as tools to identify auto-antibodies in patient sera. Patients with cancer often produce auto-antibodies, but it is not clear to what extent these responses predict T-cell-mediated cytotoxicity of tumor-cells. Within the JCIT we have a unique opportunity to address this

important question. Research conducted by PIs Olweus, Schumacher and Kolstad leads to identification of T- cell recognition elements in newly diagnosed patients. Protein array analysis of serum from the patients will determine to what extent the same proteins stimulate an antibody response. We expect to see a correlation, and if this hypothesis is confirmed, protein arrays will provide a “short-cut� for high throughput identification of candidate T cell targets. Importantly, the arrays will then also be useful for monitoring of therapies targeted to the same proteins. During 2013-2014, we have streamlined high throughput protein production and developed new and better procedures for coupling of proteins. We are currently in the production phase, with a weekly output of 400 full length human proteins from mammalian cell expression. Thus, we are on schedule with our plans to cover half of the human proteome by the end of 2015. During 2015, we expect to use smallscale custom-made arrays to measure antibody-responses to protein targets recognized by tumor-reactive T cells KG Jebsen Center for Inflammation Research, where the arrays will be used with sera from patients with auto-immune disease.

We are now in a production phase, with a weekly output of 400 full length human proteins from mammalian cell expression. The yields are sufficient for production of thousands of arrays, and the costs are approximately 10% of those of cell-free expression.

Key achievements • High throughput plasmid production.

We have obtained a collection of 10.000 cDNA clones encoding full-length human proteins from the University of Arizona. We expect to extend coverage to 12000 by the end of 2015. We have now established high throughput plasmid DNA production from bacteria in 96 well plates using liquid handing robots

•

Implementation of robotics in all steps of the production. During the past year, we have obtained three new liquid handling robots. These have now been implemented in tasks such as production, normalization and arraying of plasmid DNA, cell-free production of proteins in small volumes, and production of arrays.

•

Protein expression in mammalian cells.

The plasmids used to express proteins for this project were designed for use with cellfree expression kits. Cell-free expression is simple and rapid, but very costly. We have now successfully established expression from these plasmids in the hamster cell line BSR-T7/5. This cell line has stable ectopic expression of the T7 polymerase, which is essential for expression from the plasmids. Mammalian cell expression is expected to yield proteins that are more similar to those targeted by autoantibodies in vivo. Importantly, the new cellular system is compatible with

•

Improved coupling chemistry for protein arrays. The recombinant human proteins are fused with the small bacterial protein Glutathione S Transferase (GST). The tag allows all proteins to be immobilized to microspheres coupled with a anti-GST antibody. Before this project started the anti-GST antibody was coupled covalently to the microspheres. In 2014, we have demonstrated that bindng of biotinylated anti-GST to streptavidin beads is more effective and reproducible than covalent coupling. Thus, we have streamlined all components in array production from protein production to the coupling chemistry.

•

Successful production and testing of a pilot array with 400 human proteins.

Using the modified chemistry for immobilization of recombinant proteins to produce a pilot protein array with 400 human proteins. The functionality of the array was tested using commercially available antibodies to human proteins.

Signal to noise ratios of 2 logs were routinely obtained.

Malmberg group Developing the next generation natural killer (NK) cell therapy Scientific summary Research in the Malmberg group aims at understanding the mechanisms governing the formation of human NK cell repertoires and their functional tuning by killer cell immunoglobulin-like receptors (KIR)/HLA interactions. In an interdisciplinary effort, molecular studies of human NK cell repertoires at the single cell level are combined with an integrative cellular profiling of the NK cell repertoire in healthy individuals and in patients with cancer (Lund-Johansen, Taskén, Olweus). New insights into NK cell biology are implemented in the design of cell therapy protocols involving transfer of specific NK cell populations across HLA barriers.

During the past two years we have, together with colleagues at the Karolinska Institutet (KI) completed a first Phase I/II trial based on adoptive transfer of haploidentical NK cells to patients with refractory high-risk myeloid malignancies including MDS and AML. Six of fifteen patients evaluated so far reached complete remission (CR) and as a consequence, five of these have proceeded to an allogeneic stem cell transplant. Based on these preliminary positive results we plan to launch a Nordic NK cell trial for patients with very high-risk MDS in an upfront setting as bridge to transplant (Kolstad). Within the frame of the KG Jebsen Center, we have explored different strategies for engineering primary NK cells. Although the initial focus has been on well-characterized chimeric antigen receptor (CAR) constructs, we plan to extend this to explore the potential of retargeting human NK cells with neo- and self-specific TCRs generated by the (Olweus/ Schumacher).

KEY ACHIEVEMENTS • Over the past years we have established a methodological tool-box for robust and sensitive analysis of NK cell repertoire diversity in terms of receptor expression and functional responsiveness. In a number of recent publications the Malmberg group has delineated the principles behind the formation of complex receptor repertoires on human NK cells, including the emergence of adaptive NK cells in the context of latent viral infections. In collaboration with John Trowsdale at the University of Cambridge we demonstrated a profound effect of KIR gene copy number on global NK cell repertoires, which may have implications for genetic disease association involving epistatic interactions between KIR and HLA.

Launched a Phase I/II trial based on adoptive transfer of NK cells across HLA barriers (Performed at KI). This trial enrolls patients with refractory high-risk MDS and AML. Fifteen patients have been evaluated so far. The treatment has been well tolerated with minimal non-infectious complications. Although preliminary, we have noted some promising clinical responses with 6 patients reaching CR. Notably, clinical responses correlated with the transient detection of donor-derived NK cells 7 days after infusion. Based on these preliminary data we are now in the process of designing a Nordic NK cell trial.

•

Described the emergence of polyclonal adaptive NK cell responses in patients with TAP-deficiency, displaying low levels of HLA class I. Thus, interactions with self-HLA class I molecules shape the repertoire of expanding NK cells during adaptive NK cell responses, but are not a prerequisite for the response to occur.

The emergence of adaptive NK cells in TAP-deficient patients may contribute to anti-viral immunity and their unexpectedly low incidence of severe viral infections.

Olweus group Our main focus is to develop new strategies for T-cell based cancer immunotherapy and to perform penetrating mechanistic analyses of the immune responses in clinical immunotherapy trials Scientific summary Our main focus is to develop new strategies for T-cell based cancer immunotherapy and to perform penetrating mechanistic analyses of the immune responses in clinical immunotherapy trials. We identify T-cell receptors that mediate efficient immune responses to self-antigens or neo-antigens for future genetic engineering of T cells for adoptive cell therapy.

The focus of the’ group is to develop new strategies for T-cell based immunotherapy of cancer, with the main emphasis on leukemia and lymphoma. Our main approaches aim at targeting 1) wild-type self-antigens with cell-type restricted expression, and 2) altered peptides encoded by cancer-specific mutations, so-called neo-antigens. A single self-antigen can potentially be used as a target in a large number of patients.

The challenge is to overcome tolerance. In a series of articles, we have demonstrated that T cells that recognize self-peptides on allogeneic (foreign) HLA-A2 with high avidity and specificity can be obtained by priming with dendritic cells engineered to express allogeneic HLA-A2 complexed with self-peptides. Within the Center, this method has been further developed into a new technology platform that allows high-throughput identification of T-cell epitopes and reactive T cells, in collaboration with the Schumacher group. The Schumacher group uses their new technology to identify the TCR sequenc-

es from a large number of these T cells. This provides a basis for TCR gene transfer. Two TCRs used to re-direct peripheral blood T cells specifically killed HLA-A2pos B cells, shown in collaboration with Kolstad and the Malmberg group. Studies are ongoing to test these TCRs in murine models.

A major effort to target neo-antigens is centered around clinical trials on follicular lymphoma conducted by Kolstad. In LYMVAC-1, the patients were treated with experimental local immunotherapy (see “The Patients�). Clinical responses were strongly correlated with systemic CD8 T-cell mediated anti-tumor responses, as measured in a novel setup designed by the Olweus group.

In an ongoing collaboration with Schumacher, tumor mutations and potential T-cell targets among these will be characterized in biobanked material from the responder patients, alongside comparative TCR repertoire analyses in tumor and peripheral blood.

Anti-tumor antibodies in serum from the responder patients will be characterized using a novel flow cytometry-based protein array developed by Lund-Johansen. Moreover, Olweus and Schumacher have demonstrated the possibility to target an unused repertoire of patient-derived neo-antigens using T cells from healthy donors. This approach opens new possibilities to enable effective personalized immunotherapy.

Schumacher group

The group aims to understand what the critical antigens are for human tumor regression Scientific summary The Schumacher group is focused on the analysis and manipulation of tumor-specific T cell responses. Using in-house developed technologies, the group aims to understand what the critical antigens are for human tumor regression The focus of the Schumacher group is twofold: I) To understand what T cells ‘see’ on cancer cells in clinically effective immunotherapies, and II) To develop approaches for the genetic engineering of tumor-specific T cell immunity when otherwise lacking.

With the development of approaches to interrogate T cell responses against patient-specific mutant antigens, the former line of research has expanded substantially over the past 2 years. General goals in this research line are to understand how T cell responses against patient-specific antigens are influenced by clinical interventions

(in one project together with Kolstad and Olweus), whether T cells directed against neo-antigens are of a superior quality as compared to T cells against shared antigens, and whether the size of the mutanome predicts the activity of cancer immunotherapies. In addition to these goals, we are also exploiting our MHC-based tools to identify T cells/ TCRs against a series of shared antigens, in collaboration with Olweus. Related to this, we are using our TCR identification technologies (initially from pools of cells, now also from single T cells) to develop TCRs against novel hematological target antigens in an experimental effort led by the Olweus group. Finally, in a joint project with the Olweus group, we have married their in vitro T-cell induction strategy with our cancer exome analysis capacities to investigate whether it is feasible to target a ‘neglected’ repertoire of patient-derived neo-antigens with T cells from healthy donors.

KEY ACHIEVEMENTS • Developed technology for the high-throughput profiling of tumor antigen-specific CD8+ and CD4+ T cell immunity. Over the past years, our group has developed MHC multimer-based technology to dissect antigen-specific CD8+ T cell responses in cancer patients.

More recently, we have also developed a strategy to analyze (neo-antigen specific) CD4+ T cell responses, which is based on the use of oncogene-immortalized autologous APCs (Linnemann et al., Nat Med 2015). A main use of these technologies has been to describe tumor antigen specific T cell responses in melanoma and more recently NSCLC patients upon therapy (see below). In parallel, this toolbox has been used to isolate T cell populations specific for a number of lineage antigens (PNAS 2014, co-publication w/ Olweus and Lund-Johansen). Following validation, TCRs isolated from such T cells can be utilized to generate gene-modified T cell populations to target hematological malignancies.

• Described the frequent occurrence of neo-antigen specific CD8+ T cell and CD4+ T cell responses in melanoma.

Using the above-mentioned toolbox, we have demonstrated that both neo-antigen specific CD4+ and CD8+ T cell responses are frequent in melanoma patients (CD8: 6 out of 8 patients analyzed; CD4: 4 out of 5 patients analyzed) (van Rooij et

al, JCO 2013, Linnemann et al., Nat Med 2015). Based on the mutational load in melanoma relative to that in other tumor types (Nature 2013), these data can also be utilized to predict the formation of neo-antigen repertoires in other human tumor types.

• Provided evidence for a role of neo-antigen specific T cell reactivity in the clinical effects of checkpoint blockade and personalized immunotherapy. We have analyzed the effect of anti-CTLA4 treatment and anti-PD1 treatment in a melanoma and NSCLC patient who showed clinical responses to checkpoint blockade (van Rooij et al, JCO 2013, Rizvi et al. Science 2015). These analyses demonstrate that both types of checkpoint blockade can result in enhanced neo-antigen specific CD8+ T cell immunity. We have furthermore obtained data in collaboration with T. Chan, MSKCC showing that in NSCLCs treated with anti-PD1, a high nonsynonymous mutation burden is strongly predictive of clinical efficacy. These data provide additional support for the notion that neo-antigen recognition forms an important ingredient of the effects of anti-checkpoint therapies in tumors such as melanoma and NSCLC. This work further relates to data showing that personalized immunotherapy can be enabled using donor-derived neo-antigen specific T cells (ms in prep co-authored by Olweus) N.A.

Taskén group The inhibition of Treg activity will enhance the effectiveness of adoptive T-cell therapies being developed in the centre Scientific summary Our main focus is to understand why the immune system sometimes turns off its ability to recognize and kill cells in an expanding malignant tumor. We aim to understand how tumors develop immune evasion strategies, what mechanisms operate in different cancers and how we can perturb such immunoinhibitory signals to boost anti-tumor immunity.

Regulatory T cells (Tregs) have been demonstrated to suppress immune responses to cancer cells, and their removal improves anti-tumor immunity in most cancers.

Based on our current understanding of Treg function, it is plausible that the inhibition of Treg activity will enhance the effectiveness of adoptive T-cell therapies being developed in the centre by the Olweus and Schumacher groups. The Taskén group is currently delineating the signaling cascades of inhibitory Tregs as compared with activating effector T cells, thereby aiming to identify molecules in Tregs that can be specifically targeted by small molecule inhibitors. Furthermore, the role of Tregs in suppression of anti-tumor immunity has been assessed in ovarian cancer and in pancreatic, gastric and hepatocellular carcinoma. In addition, a new potential mechanism of regulation of Treg mediated immunosuppression via gap junctions has been characterized and a chemical biology screen has delivered a set of candidate compounds to perturb this mechanism (continuing work).

The Taskén group has observed that cancer cells, as well as monocytes and Tregs, may secrete high levels of the inflammatory mediator PGE2, which suppresses effector T cell signaling and immune function. Team members have established analyses to assess effects of PGE2 on the phosphoproteome of T-cell subsets and using phosphoflow analysis in a systems biology approach developed in (ongoing), and have examined the impact on T cell signaling in patients with colorectal cancer. These studies as well as similar studies on Treg align well with ongoing studies in the Lund-Johansen (multiplexed analyses of T cell proteomics) and Malmberg (NK cell CyTOF analyses ao) groups.

Proof-of-concept that perturbing the PGE2 pathway inhibits tumor growth is already available from animal experiments and targeting strategies are being tested. Clinical impact of perturbing the PGE2 pathway by existing drugs in colorectal cancer has been assessed in a registry study coupling data from the Cancer Registry of Norway and the Norwegian Prescription Database.

Key achievements • Signaling networks elicited by T cell co-stimulation by CD28 and CD2 have been mapped in detail by phosphoflow cytometry, showing differences in activation of the proximal and distal signals, and the mechanisms have now largely been mapped (ongoing). A detailed mapping of human Treg effects on T-cell signalling has also been finalized showing how effector T cells may become suppressed or escape depending on the level of suppression.

Lymvac-1: Treating follicular lymphoma with local immunotherapy to achieve systemic effects

A major goal of the JCIT consortium has been to create new immunologic therapies that will benefit cancer patients. Recently, an early exploratory study with a novel inhouse in situ vaccine strategy was conducted with Arne Kolstad as principal investigator (Lymvac-1 trial). The target population for this trial was patients with disseminated untreated or relapsed follicular non-Hodgkin`s lymphoma (FL). Patients with disseminated disease stage III or IV and are considered to be incurable by standard therapies available today. Remissions can be achieved with monoclonal antibody therapy, chemotherapy or the combination of both. However, relapses tend to occur with closer intervals and in the end treatment options are scarce.

There is evidence to support that immune surveillance is of importance in FL and we therefore decided to conduct a study aiming to overcome tolerance against the cancer by a novel immunostimulatory approach.

Local immunotherapies administered intra-tumorally have thus far not received much attention relative to systemic immunotherapies. In our study we investigated the possible concerted actions of local radiation and in situ immunostimulatory strategies to induce T-cell mediated immune responses resulting in clinical effects.

Fourteen patients with stage III/IV follicular lymphoma (FL) grade I-IIIA, of which the majority were previously untreated, received sequential intranodal immunotherapy targeting single lymph nodes. Three different treatment modalities were combined; radiotherapy (RT), injections of low-dose rituximab (5 mg) and immature autologous dendritic cells (DCs). Clinical responses were observed in five out of fourteen patients (36%), and two patients had durable complete remissions. For this study, the group of Johanna Olweus designed a new

assay to monitor T-cell mediated anti-tumor reactivity. Notably, vaccination-induced systemic CD8 and also CD4 T-cell mediated responses against autologous tumor cells were detected in peripheral blood in responding patients. Reduction in total tumor volume was closely correlated with the magnitude of vaccination-induced systemic CD8 T-cell mediated responses, and immune responders showed prolonged time to next treatment compared to non-responders.

Our in situ vaccine strategy could override local suppression of T-cell responses targeting tumor. Moreover, activated tumor-reactive T cells were rendered resistant to further suppression. We hypothesize that pre-conditioning of the lymphoma node by radiotherapy provides an ample source of “danger signals� to facilitate DC maturation and presentation of tumor-antigens to T cells. Memory T cells migrating into the irradiated lymph nodes can then make contact with and become primed by the injected and matured DCs. Moreover, intranodally administrered DCs can migrate to distal lymph nodes, opening the possibility that DCs bring tumor-antigen to distant sites for further T-cell priming. In some patients, this resulted in the elimination of bulky tumor masses, likely caused by T-cell migration to distant tumor sites.

Results from this study were published in Blood 2014 with Kolstad as first author and Olweus as last author. The study received considerable attention, and a Commentary

by Josh Brody appeared in the same issue of Blood. Kolstad and Olweus furthermore discussed potential mechanisms of action in an invited Author-view article in Oncoimmunology, 2015.

improve and prolong the effects observed in Lymvac-1. A new study is planned to start in 2015 (Lymvac-2) where we keep the local immunotherapy platform unchanged, but add on a check-point inhibitor administered systemically. The pharmaceutical company Merck has agreed to provide the anti-PD1 antibody Pembrolizumab free of charge for 20 patients with FL. In this phase II study patients will be recruited from all regions in Norway and treated at Oslo University Hospital Radiumhospitalet. As in Lymvac-1, the major end-points will be clinical and immunological responses.

Recruitment time is estimated to be 2 years.

We expect shorter accrual time for Lymvac-2 than Lymvac-1, given the attention results from Lymvac-1 have received in the scientific community and media.

Harnessing Natural Killer Cells in Cancer Therapy KJM is the co-ordinating investigator of a first phase I/II clinical trial based on adoptive transfer of haploidentical NK cells to patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) who have no other treatment options. This trial is carried out at the Karolinska Institutet (KI). The treatment has been well tolerated. Interestingly, six patients achieved complete remission (CR) that lasted at least 3 months. Four of these patients were transplanted within 6 months after NK cell treatment. Notably, the clinical responses correlated with the emergence of donor-derived NK cells at day 7 post adoptive transfer.

Based on the positive results in this first trial we aim to establish generic models for national and international scale-up of NK cell-based cell therapy strategies, either alone or in combination with other treatment modalities such as antibodies. To pave the way for a more generic platform, we propose to launch a multicenter Nordic Phase II trial that capitalizes on the promising results of the completed Phase I/ II trial. The Nordic trial will be co-ordinated from the K.G. Jebsen Center at the University of Oslo.

Innovation

Schumacher’s biotech company T Cell Factory B.V acquired by Kite Pharma. Kite Pharma has acquired T cell factory BV (TCF), previously owned by Schumacher and the NKI. Financial terms of Kite’s acquisition of TCF include an upfront payment of up to Euro 20.0M. Kite Pharma, founded in 2009, is a clinical-stage biopharmaceutical company focused on the development and commercialization of novel cancer immunotherapy products. Schumacher has been appointed Chief Scientific Officer of Kite’s European headquarters. Scientists from the Schumacher laboratory will work closely with Kite scientists to develop new TCR candidates against mutated proteins and thereby generate truly tumor-specific therapy. The agreement greatly strengthens the possibilities for translating discoveries made by researchers in the JCIT into new therapies.

Olweus group and Inven2 have filed a patent for new technology to discover immune-recognition elements in cancer cells Identification of immune-recognition elements, or epitopes, is a bottleneck in immuno-therapy. Established methods for discovery of T cell epitopes involve screening of peptide libraries or detection of MHCbound peptides by mass spectrometry. In an article published in the prestigious journal the Proceedings of the National Academy of Sciences USA, the Olweus group describes a new approach that eliminates these laborious and time-consuming steps. The method is in part a novel combination of technologies previously described by the Olweus and Schumacher groups. Results obtained using the method show that the number of immune-recognition elements is far greater than previously expected. The group has received an innovation grant from the BIOTEK2021 program of the Research Council of Norway to pursue therapeutic applications of T-cell receptors reactive to peptides identified using the technology.

Lund-Johansen group has validated the commercial potential of their protein array technology Lund-Johansen and Inven2 are currently finalizing an innovation project, which aims to explore the commercial potential of FLJ’s protein array technology. The project is funded by the FORNY programme of the Research Council of Norway. In collaboration with US antibody manufacturer Novus Biologicals, Lund-Johansen has shown that his array technology can be applied for high-throughput validation of antibodies.

Validation is the bottleneck in antibody production, and poorly validated antibodies represent a frequent cause of irreproducibility of bio-medical research. Inven2 and Lund-Johansen are currently negotiating with several candidate industry partners.

The aim is to establish a Norwegian biotech company based on the array technology.

The Taskén group has identified hit compounds that inhibit the activity of regulatory T cells (Treg).

Previously, the Taskén group has shown that prostaglandin E2 (PGE2) activates Treg cells via a pathway that involves protein kinase A (PKA). Direct targeting of PKA has proven to be difficult due to the ubiquitous expression of the kinase and the lack of oral bioavailability of cAMP antagonists that target the PKA regulatory subunit (cAMP receptor) expressed lymphocytes. However, the Taskén group has discovered cell type-specific adaptor and anchoring proteins that have a role in scaffolding signalling enzymes downstream of PKA in effector T cells and regulatory T cells. The group receives grants from the Norwegian Cancer Society and the University of Oslo to pursue development of compounds that interfere with the immunomodulaing signalling machinery.

Education and Career JCIT: Fostering Scientific Careers

Johannes Landskron Scientist in the Taskén Group.

Recruited in 2008 from University of Regensburg where he worked on Drosophila clock proteins for this PhD. Developed extensive flow cytometry expertise in the Taskén group as a postdoc and researcher and built a robotic pipeline that supports both automated phosphoflow analyses and chemical biology screens by flow cytometry. Project: High throughput screening for novel small molecule regulators of FoxP3 in regulatory T cells. “If our strategy works, we may be able to manipulate levels of Treg activation and thereby suppression of anti-tumor immunity.”

Erlend Strønen MD and PhD student in Olweus group. Erlend started his research career taking the research curriculum during medical studies at the University of Oslo. He got hooked, and continued research to unravel how non-tolerized T cell repertoires can be utilized to enable cancer immunotherapy.

“We believe that inefficient immune responses to cancer in patients can be overcome by adoptive transfer of immunity from healthy donors”.

Jodie Goodridge

Scientist in Malmberg Group. Recruited from Fred Hutchinson Cancer Research Center in 2013. Project: Understanding the cellular basis behind the functional maturation of natural killer cells. “If successful, our work will pave the way for the next generation of NK cell therapy based on guided differentiation of specific NK cell subsets”.

SAB Helping us improve further â&#x20AC;&#x201C; Scientific Advisory Board visit 2014

Johanna Olweus presenting to the members of the SAB. Foto: Terje Heiestad, Millimeter Press AS

Already at the point when the application for a center was sent to the K.G. Jebsen Foundation, a Scientific Advisory Board (SAB) was in place to guide us in the event that we obtained funding. We feel very fortunate to have Fred Falkenburg (Leiden Medical University, the Netherlands), Rolf Kiessling (Karolinska Institute, Stockholm, Sweden) and Hans Stauss (University College London, UK, and chairman of the SAB) in our SAB. These three scientists are at the international forefront and have a broad competence that matches our translational program perfectly, ranging from basic immunology related to cancer immunotherapy to clinical immunotherapy trials. The first SAB meeting was held in Oslo in November 2014, almost 1.5 years since the opening of

the center. Late enough to evaluate if we were on the right track, and early enough to ensure that suggested improvements can be implemented during the lifetime of the center. After two intense days of scientific presentations and discussions we were strengthened in our belief in the program and inspired to follow advice that can further extend the synergies between the partnering groups and focus our research even further. The recommendations were included in the research plan and progress report for the K.G. Jebsen Foundation submitted in January 2015. â&#x20AC;&#x153;The board was impressed with the quality and the breadth of the translational research programme of the Center, which includes discovery science combined with a clear strategy to move research developments into clinical trials in patientsâ&#x20AC;?

Key Events

Norwegian Cancer Symposium 2014 Norwegian Cancer Symposium 2014 â&#x20AC;&#x153;Harnessing innate and adaptive immunity in cancer therapyâ&#x20AC;? was organized by Malmberg and Olweus June 10-12, 2014 (http://www.cancersymposia.no). Norsk Hydro Fond sponsored the meeting, which attracted many internationally leading scientists in immunotherapy as speakers, such

as Carl June, Ton Schumacher, Cassian Yee, Martin Pule, Rolf Kiessling, Dean Anthony Lee and Jeff Miller. Overlooking the view of the Oslo fjord, approximately 100 delegates enjoyed cutting edge scientific talks and interactive poster sessions at the Holmenkollen Park Hotel.

Some even dared ziplining from the top of the Ski Jump.

Internal activities Scientific Retreats

April 10th -12th 2015 Dr. Holms hotel at Geilo In April 2015 the center organized yet another successful internal scientific retreat. During this two day event we followed presentations from all of the groups of the center, and participated in interesting scientific discussions.

Importantly, we also found the time to enjoy downhill skiing and cross country skiing, facilitating non-scientific interactions between center participants.

April 10th-11th 2014 Thorbjørnrud Hotel at Jevnaker This was the first internal scientific retreat organized by the K.G. Jebsen Center for Cancer Immunotherapy. A two day event with scientific presentations and discussions. This was also an opportunity for the different groups of the JCIT to get to know each other better.
