Abstract
OBJECTIVE We recently showed that the anti-helminthic compound mebendazole (MBZ) has immunomodulating activity by inducing a M2 to M1 phenotype switch in monocyte/macrophage models. In the present study we investigated the potential role of protein kinases in mediating this effect. RESULTS MBZ potently binds and inhibits Dual specificity tyrosine-phosphorylation-regulated kinase 1B (DYRK1B) with a Kd and an IC50 of 7 and 360 nM, respectively. The specific DYRK1B inhibitor AZ191 did not mimic the cytokine release profile of MBZ in untreated THP-1 monocytes. However, in THP-1 cells differentiated into macrophages, AZ191 strongly induced a pro-inflammatory cytokine release pattern similar to MBZ and LPS/IFNγ. Furthermore, like MBZ, AZ191 increased the expression of the M1 marker CD80 and decreased the M2 marker CD163 in THP-1 macrophages. In this model, AZ191 also increased phospho-ERK activity although to a lesser extent compared to MBZ. Taken together, the results demonstrate that DYRK1B inhibition could, at least partly, recapitulate immune responses induced by MBZ. Hence, DYRK1B inhibition induced by MBZ may be part of the mechanism of action to switch M2 to M1 macrophages.

Abstract
BACKGROUND Regulatory immune cells may modulate the lymphoma microenvironment and are of great interest due to the increasing prevalence of treatment with immunotherapies in lymphoma patients. The aim was to explore the composition of different immune regulatory cell subsets in the peripheral blood of newly diagnosed lymphoma patients in relation to treatment outcome. METHODS Forty-three newly diagnosed patients with lymphoma were included in the study; 24 with high-grade B-cell lymphoma (HGBCL) and 19 with classical Hodgkin lymphoma (cHL). Peripheral blood was prospectively collected and immune regulatory cells were identified by multi-color flow cytometry and analyzed in relation to healthy blood donors and clinical characteristics and outcome. RESULTS The percentage of CD3-positive T-cells was lower (p = 0.03) in the peripheral blood of lymphoma patients at diagnosis compared to healthy blood donors regardless of lymphoma subtype, although statistically, neither the percentage of monocytes (p = 0.2) nor the T-cell/monocyte ratio (p = 0.055) differed significantly. A significant decrease in the percentage of a subset of regulatory NK cells (CD7+/CD3-/CD56bright/CD16dim/-) was identified in the peripheral blood of lymphoma patients compared to healthy blood donors (p = 0.003). Lymphoma patients also had more granulocytic myeloid-derived suppressor cells (MDSCs) (p = 0.003) compared to healthy blood donors, whereas monocytic MDSCs did not differ significantly (p = 0.07). A superior disease-free survival was observed for cHL patients who had an increase in the percentage of granulocytic MDSCs (p = 0.04). CONCLUSIONS An altered profile of immune cells in the peripheral blood with a decrease in T-cells and regulatory NK-cells was observed in newly diagnosed lymphoma patients. CHL patients with higher percentages of regulatory NK cells and higher percentages of granulocytic MDSCs might have a better outcome, although the number of patients was low.

Abstract
Abstract
In recent years, cancer immunotherapies significantly advanced the clinical management of metastatic melanoma. In particular, treatment with immune checkpoint inhibitors increased survival rates compared with standard therapy. However, not all patients benefit from checkpoint blockade. Primary treatment resistance is connected to poor T-cell infiltration in the tumors. This can be due to limited activation of antigen-presentation cells such as dendritic cells (DCs) and the high threshold of activating low-affinity T-cells that may respond to the tumor antigens. CD27 signaling in T-cells during activation lowers the T-cell receptor signaling threshold, which may be important to activate tumor-targeting T-cells. Secondary resistance to checkpoint blockade therapy includes loss of MHC-I on the tumor cells. Hence, inducing natural killer (NK) cell activation in parallel to antitumor T-cells may be crucial. LOAd703 was designed to optimize antitumor immune activation. LOAd703 is an oncolytic adenovirus (serotype Ad5/35) carrying two immunostimulatory transgenes; a trimerized membrane-bound CD40 ligand (TMZ-CD40L) and the full-length 4-1BB ligand (4-1BBL) (patent filed: PCT/EP2015/057489). The viral replication is restricted to tumor cells with a hyperphosphorylated retinoblastoma pathway due to a deletion in E1A, but transgenes are expressed under the control of a cytomegalovirus (CMV) promoter, which enables transgene expression even in the surrounding tumor microenvironment. Herein, we investigated LOAd703 in a melanoma model and its immunostimulatory effect on DC maturation to induce antigen-specific T-cell responses. LOAd703 infected the human melanoma cell line 526-mel and efficiently induced tumor cell death as evaluated by MTS viability assay. The viability of infected cells was reduced to 15% at 72 hours post infection compared to uninfected cells. Transgene expression of both TMZ-CD40L and 4-1BBL was confirmed by flow cytometry post infection. To evaluate the immunostimulatory capacity of LOAd703, immature DCs were differentiated from CD14+ monocytes using granulocyte-macrophage colony-stimulating factor and interleukin-4 and infected with virus. LOAd703-infected DCs upregulated the expression of maturation markers, such as CD83, CD86 and MHC molecules as analyzed by flow cytometry. Interestingly, CD70 that is required for CD27 stimuli of T-cells was highly upregulated on the DCs using LOAd703. Furthermore, the chemokine receptor CCR7 and the adhesion molecule ICAM-1 were increased upon LOAd703 infection, which are crucial for lymph node homing and the initiation of a systemic response. Next, the functional capacity of LOAd703-matured DCs to induce antigen-specific T-cell responses was assessed in a CMV model, in which CMV-peptide pulsed DCs are utilized to induce expansion of CMV-specific T-cells. LOAd703-matured DCs from CMV+ donors were pulsed with CMV-peptide and co-cultured with autologous peripheral blood mononuclear cells for 11 days. LOAd703-matured DCs were able to expand CMV-specific T-cells, but to a lower degree than the positive control Poly I:C matured DCs. However, the CMV-specific T-cells expanded from the positive control had higher expression of PD-1 compared to the LOAd703 group, indicating that LOAd703 leads to the expansion of less exhausted and potentially more functional T-cells. Moreover, LOAd703 also induced a massive expansion of NK cells, which is probably driven by 4-1BBL. In conclusion, LOAd703 killed human melanoma cells by oncolysis and induced the expression of TMZ-CD40L and 4-1BBL in infected cells. Furthermore, LOAd703 infection activated DCs to express costimulatory molecules including high levels of CD70 and CCR7, which in turn could promote the expansion of antigen-specific T-cells with low PD-1 expression, as well as the potent expansion of NK cells.

Abstract
IL-6 plays a role in cancer pathogenesis via its connection to proteins involved in the formation of desmoplastic stroma and to immunosuppression by driving differentiation of myeloid suppressor cells together with TGF-β. Inhibition of IL-6 signaling in the tumor microenvironment may, thus, limit desmoplasia and myeloid suppressor cell differentiation. CD40 signaling can further revert myeloid cell differentiation toward antitumor active phenotypes. Hence, the simultaneous use of IL-6 blockade with CD40 stimuli may tilt the tumor microenvironment to promote antitumor immune responses. In this paper, we evaluated the mechanisms of LOAd713, an oncolytic adenovirus designed to block IL-6R signaling and to provide myeloid cell activation via a trimerized membrane-bound isoleucine zipper (TMZ) CD40L. LOAd713-infected pancreatic cancer cells were killed by oncolysis, whereas infection of stellate cells reduced factors involved in stroma formation, including TGF-β-1 and collagen type I. Virus infection prevented IL-6/GM-CSF-mediated differentiation of myeloid suppressors, but not CD163 macrophages, whereas infection of dendritic cells led to upregulation of maturation markers, including CD83, CD86, IL-12p70, and IFN-γ. Further, IL-6R blockade prevented upregulation of programed death ligand 1 (PD-L1) and PD-1 on the stimulated dendritic cells. These results suggest that LOAd713 can kill infected tumor cells and has the capacity to affect the tumor microenvironment by stimulating stellate cells and myeloid suppressors with TMZ-CD40L and IL-6R blockade. Gene transfer of murine TMZ-CD40L prolonged survival in an animal model. LOAd713 may be an interesting therapeutic option for cancers connected to IL-6 signaling, such as pancreatic cancer.

Abstract
Abstract
This study aims to evaluate if immunostimulatory gene therapy is a good enhancer of checkpoint blockade therapy. Lung cancer is a deadly disease responding poorly to conventional therapy. Checkpoint blockade antibodies inhibiting PD-1/PD-L1 signaling have shown significant clinical benefit. Nevertheless, there is still room for improving overall survival rates. Since the success of PD-1 blockade therapy prerequisites the presence of tumor-reactive T cells, we hypothesized that an activating immunotherapy with high potency to stimulate T cell responses would be an ideal candidate to combine with anti-PD-1 antibody treatment. LOAd703 is a replication-restricted adenovirus serotype 5/35. It is armed with two immunostimulatory transgenes, 4-1BB ligand (4-1BBL) and a trimerized, membrane-bound human CD40 ligand (TMZ-CD40L) (PCT/EP2015/057489). Both molecules are key co-stimulatory molecules in the dendritic cell (DC)/T cell synapse. The capacity of LOAd703 was tested using the lung cancer cell lines A549 and H727. Infected tumor cells were killed by oncolysis in a 72hr MTS viability assay with high dose virus (100MOI) which also translated into tumor control in a xenograft mouse model. In tumor cell co-culture with peripheral blood mononuclear cells (PBMCs) (Incucyte), the PBMCs were rapidly tolerized by the tumor microenvironment and did not proliferate, nor kill, the allogeneic tumor. Addition of anti-PD-1 antibody did not increase tumor cell apoptosis as a monotherapy. If OKT3/IL2 was added to the co-culture, apoptosis was confirmed in the cultures peaking at day 5. Combination of OKT3/IL2 with anti-PD-1 antibody significantly enhanced the effect. LOAd703 was added to tumor cell/PBMC co-cultures at a low MOI to delay oncolysis but allow transgene expression. LOAd703 rapidly induced caspase activation in the tumor cells, starting already at day 2 and the activity was continuously rising throughout the experiment. Combining LOAd703 with anti-PD-1 antibody significantly increased apoptosis induction of tumor cells. A control virus lacking immunostimulatory transgenes was less efficient. At endpoint, LOAd703 plus anti-PD-1 was twice as effective as OKT3/IL2 plus anti-PD-1. Immune cells were analyzed by flow cytometry and supernatants taken for cytokine analysis. The T cells were increased in the same groups as tumor cell killing was previously noted. IFNg, TNF, IL2 were all enhanced by LOAd703 and OKT3/IL2. The LOAd703 virus does not infect murine cells since it targets human CD46. However, murine B cells can take up the virus by another route albeit with poor efficacy. Nevertheless, the murine A20 B cell lymphoma was used as a surrogate syngeneic model to test the ability of LOAd703 to potentiate aPD-1 therapy. In line with in vitro data, LOAd703 could enhance in vivo tumor control of anti-PD-1 therapy. IFNg and TNF were enhanced in serum of combination animals. In conclusion, LOAd703 is a potent stimulator of T cell responses and potentiates the effect of aPD-1 therapy. LOAd703 is currently in clinical phase I investigation prior initiating combination studies in suitable indications such as lung cancer.

Abstract
PURPOSE The chimeric antigen receptor (CAR) T-cell therapy has been effective for patients with CD19+ B-cell malignancies. Most studies have investigated the second-generation CARs with either CD28 or 4-1BB costimulatory domains in the CAR receptor. Here, we describe the first clinical phase I/IIa trial using third-generation CAR T cells targeting CD19 to evaluate safety and efficacy. PATIENTS AND METHODS Fifteen patients with B-cell lymphoma or leukemia were treated with CAR T cells. The patients with lymphoma received chemotherapy during CAR manufacture and 11 of 15 were given low-dose cyclophosphamide and fludarabine conditioning prior to CAR infusion. Peripheral blood was sampled before and at multiple time points after CAR infusion to evaluate the persistence of CAR T cells and for immune profiling, using quantitative PCR, flow cytometry, and a proteomic array. RESULTS Treatment with third-generation CAR T cells was generally safe with 4 patients requiring hospitalization due to adverse reactions. Six of the 15 patients had initial complete responses [4/11 lymphoma and 2/4 acute lymphoblastic leukemia (ALL)], and 3 of the patients with lymphoma were in remission at 3 months. Two patients are still alive. Best predictor of response was a good immune status prior to CAR infusion with high IL12, DC-Lamp, Fas ligand, and TRAIL. Responding patients had low monocytic myeloid-derived suppressor cells (MDSCs; CD14+CD33+HLA-DR-) and low levels of IL6, IL8, NAP3, sPDL1, and sPDL2. CONCLUSIONS Third-generation CARs may be efficient in patients with advanced B-cell lymphoproliferative malignancy with only modest toxicity. Immune profiling pre- and posttreatment can be used to find response biomarkers.

Abstract
Mebendazole (MBZ) was recently shown to induce a tumor suppressive M1 phenotype in THP-1 monocytes and macrophages. In the present study the immune effects of MBZ was further investigated using human peripheral blood mononuclear cells (PBMCs) co-cultured with tumour cells. The Biomap platform was used to screen for biomarkers induced from MBZ exposed co-cultures of T-cell receptor activated PBMCs, HT29 colon cancer cells and either human fibroblasts or human umbilical vein endothelial cells (HUVEC) cells. In these co-culture systems MBZ at 0.3-10 μM induced significant increases in TNFα and IFNγ indicating immune stimulation. PBMC cultures alone were subsequently tested for activation status and only in PBMCs activated by CD3/IL2 stimulation and MBZ, at a clinically achievable concentration, was able to increase PBMC clustering and release of pro-inflammatory IFNγ, TNFα, IL6 and IL1β cytokines. Moreover, when PBMC cultures were functionally tested for immune cell killing of lung cancer A549NucLightRed cells, MBZ significantly increased tumour cell apoptosis and reduced the number of surviving tumour cells. This effect was dependent on the presence of CD14 monocytes/macrophages in the co-culture. In summary, MBZ potentiated the immune stimulatory and anticancer effects of anti-CD3/IL2 activated PBMCs which could be relevant to explain the anticancer activity of MBZ observed in the clinic.

Abstract
Introduction Therapy with chimeric antigen receptor T (CART) cells for hematological malignancies has shown promising results. Effectiveness of CART cells may depend on the ratio of naive (TN) vs. effector (TE) T cells, TN cells being responsible for an enduring antitumor activity through maturation. Therefore, we investigated factors influencing the TN/TE ratio of CART cells. Materials and methods CART cells were generated upon transduction of peripheral blood mononuclear cells with a CD19.CAR-CD28-CD137zeta third generation retroviral vector under two different stimulating culture conditions: anti-CD3/anti-CD28 antibodies adding either interleukin (IL)-7/IL-15 or IL-2. CART cells were maintained in culture for 20 days. We evaluated 24 healthy donors (HDs) and 11 patients with chronic lymphocytic leukemia (CLL) for the composition of cell subsets and produced CART cells. Phenotype and functionality were tested using flow cytometry and chromium release assays. Results IL-7/IL-15 preferentially induced differentiation into TN, stem cell memory (TSCM: naive CD27+ CD95+), CD4+ and CXCR3+ CART cells, while IL-2 increased effector memory (TEM), CD56+ and CD4+ T regulatory (TReg) CART cells. The net amplification of different CART subpopulations derived from HDs and untreated CLL patients was compared. Particularly the expansion of CD4+ CARTN cells differed significantly between the two groups. For HDs, this subtype expanded >60-fold, whereas CD4+ CARTN cells of untreated CLL patients expanded less than 10-fold. Expression of exhaustion marker programmed cell death 1 on CARTN cells on day 10 of culture was significantly higher in patient samples compared to HD samples. As the percentage of malignant B cells was expectedly higher within patient samples, an excessive amount of B cells during culture could account for the reduced expansion potential of CARTN cells in untreated CLL patients. Final TN/TE ratio stayed <0.3 despite stimulation condition for patients, whereas this ratio was >2 in samples from HDs stimulated with IL-7/IL-15, thus demonstrating efficient CARTN expansion. Conclusion Untreated CLL patients might constitute a challenge for long-lasting CART effects in vivo since only a low number of TN among the CART product could be generated. Depletion of malignant B cells before starting CART production might be considered to increase the TN/TE ratio within the CART product.

Abstract
OBJECTIVE The classical Hodgkin lymphoma (cHL) tumor microenvironment shows an ongoing inflammatory response consisting of varying degrees of infiltrating eosinophils, mast cells, macrophages, regulatory T lymphocytes (Tregs), and activated lymphocytes surrounding the malignant cells. Herein, different immune signatures are characterized and correlated with treatment outcome. METHODS Tumor-infiltrating leukocytes were phenotyped in biopsies from 459 patients with cHL. Time to progression (TTP) (primary progression, relapse, or death from cHL) and overall survival were analyzed using Cox proportional hazards regression. RESULTS The leukocyte infiltration in the microenvironment was highly diverse between patients and was categorized in 4 immune signatures (active, anergic, innate, or mixed). A high proportion of Tregs (anergic) resulted in shorter TTP (median 12.9-year follow-up) in age-adjusted analyses (hazard ratio = 1.82; 95% confidence interval 1.05-3-15). Epstein-Barr virus (EBV)-positive cases had higher proportions of macrophages and activated lymphocytes than EBV negative, but neither of those leukocytes predicted prognosis. CONCLUSIONS Abundant Tregs (anergic signature) indicate a shorter TTP, particularly in younger patients. This is probably due to a reduced ability of the immune system to attack the tumor cells. Our data warrant further investigation if these suggested immune signatures could predict outcome of immunotherapy such as immune checkpoint inhibitors.

Abstract
Background AdCD40L is an immunostimulatory gene therapy under evaluation for advanced melanoma, including ocular melanoma. Herein, we present the final data of a Phase I/IIa trial using AdCD40L alone or in combination with low dose cyclophosphamide +/- radiation therapy. Methods AdCD40L is a replication-deficient adenovirus carrying the gene for CD40 ligand (CD40L). Twenty-four patients with advanced melanoma were enrolled and treated with AdCD40L monotherapy, or combined with cyclophosphamide +/- single fraction radiotherapy. The patients were monitored for 10 weeks using immunological and radiological evaluations and thereafter for survival. Results AdCD40L treatment was safe and well tolerated both alone and in combination with cyclophosphamide as well as local radiotherapy. Four out of twenty-four patients had >1 year survival. Addition of cyclophosphamide was beneficial but adding radiotherapy did not further extend survival. High initial plasma levels of IL12 and MIP3b correlated to overall survival, whereas IL8 responses post-treatment correlated negatively with survival. Interestingly, antibody reactions to the virus correlated negatively with post IL6 and pre IL1b levels in blood. Conclusions AdCD40L was safely administered to patients and effect was improved by cyclophosphamide but not by radiotherapy. Immune activation profile at baseline may predict responders better than shortly after treatment.

Abstract
Abstract
The tumor microenvironment (TME) consists of tumor cells and stroma, including fibroblasts, blood vessels, immune cells and extracellular matrix. The TME supports tumor progression, metastasis as well as resistance to cancer therapeutics. In pancreatic cancer, the TME is dense due to overproduction of collagen and the tumor is infiltrated with suppressive myeloid cells such as M2 macrophages and myeloid suppressor cells. One key regulator of myeloid cells is CD40, a receptor expressed on a variety of cell types. CD40/CD40L signaling results in production of cytokines and chemokines by myeloid cells but also endothelial and epithelial cells to alert the immune system of immediate danger. 4-1BB is expressed by lymphocytes and dendritic cells (DCs). Stimulation via 4-1BBL drives lymphocyte expansion and regulates memory formation. IL6 signaling leads to STAT3 phosphorylation in myeloid cells and tumor cells leading to suppressive phenotypes, tumor proliferation, and angiogenesis. Further, STAT3 signaling enhances production of TGFb, which in turn leads to overexpression of collagen. We have constructed a family of oncolytic adenoviruses (LOAd) activating the CD40, 4-1BB and/or inhibiting IL6 signaling. The LOAd viruses (-, 700, 703, 713) were investigated for their capacity to activate human monocyte-derived DCs as well as their effect on pancreatic tumor cells and stroma (fibroblastic stellate cells, endothelial cells) using flow cytometry, MTS assay and ProSeek Proteomics. The LOAd viruses expressing a trimerized CD40L, 4-1BBL and/or a scFv IL6R showed efficient oncolysis of tumor cells but primary stellate cells were unaffected. However, stellate cells reduced tumor-promoting factors such as FGF5, PlGF, amphiregulin, Gal3, TGFb and collagen type I. Dendritic cells increased costimulators, cytokines as well as chemokines but PDL1 was not expressed when IL6/STAT3 was blocked. Infected endothelial cells upregulated receptors important for lymphocyte transmigration (ICAM, VCAM and E-Selectin). Taken together, our data demonstrates that it is possible to utilize oncolytic adenoviruses to spark immune activation at the same time changing biological processes via STAT3 blockade and/or CD40/4-1BB pathway activation to reduce factors that promotes tumor progression.

Abstract
Purpose: Pancreatic cancer is a severe indication with short expected survival despite surgery and/or combination chemotherapeutics. Checkpoint blockade antibodies are approved for several cancer indications, but pancreatic cancer has remained refractory. However, there are clinical data suggesting that stimulation of the CD40 pathway may be of interest for these patients. Oncolytic viruses armed with immunostimulatory genes represent an interesting approach. Herein, we present LOAd703, a designed adenovirus armed with trimerized CD40L and 4-1BBL that activates the CD40 and 4-1BB pathways, respectively. As many cells in the tumor stroma, including stellate cells and the infiltrating immune cells, express CD40 and some 4-1BB, we hypothesize that LOAd703 activates immunity and simultaneously modulates the biology of the tumor stroma.Experimental Design: Tumor, stellate, endothelial, and immune cells were infected by LOAd703 and investigated by flow cytometry, proteomics, and functional analyses.Results: LOAd703-infected pancreatic cell lines were killed by oncolysis, and the virus was more effective than standard-of-care gemcitabine. In in vivo xenograft models, LOAd703 efficiently reduced established tumors and could be combined with gemcitabine for additional effect. Infected stellate and tumor cells reduced factors that promote tumor growth (Spp-1, Gal-3, HGF, TGFβ and collagen type I), while chemokines were increased. Molecules involved in lymphocyte migration were upregulated on infected endothelial cells. Dendritic cells were robustly stimulated by LOAd703 to produce costimulators, cytokines and chemokines, and such DCs potently expanded both antigen-specific T cells and NK cells.Conclusions: LOAd703 is a potent immune activator that modulates the stroma to support antitumor responses.

Abstract
Mebendazole (MBZ), a drug commonly used for helminitic infections, has recently gained substantial attention as a repositioning candidate for cancer treatment. However, the mechanism of action behind its anticancer activity remains unclear. To address this problem, we took advantage of the curated MBZ-induced gene expression signatures in the LINCS Connectivity Map (CMap) database. The analysis revealed strong negative correlation with MEK/ERK1/2 inhibitors. Moreover, several of the most upregulated genes in response to MBZ exposure were related to monocyte/macrophage activation. The MBZ-induced gene expression signature in the promyeloblastic HL-60 cell line was strongly enriched in genes involved in monocyte/macrophage pro-inflammatory (M1) activation. This was subsequently validated using MBZ-treated THP-1 monocytoid cells that demonstrated gene expression, surface markers and cytokine release characteristic of the M1 phenotype. At high concentrations MBZ substantially induced the release of IL-1β and this was further potentiated by lipopolysaccharide (LPS). At low MBZ concentrations, cotreatment with LPS was required for MBZ-stimulated IL-1β secretion to occur. Furthermore, we show that the activation of protein kinase C, ERK1/2 and NF-kappaB were required for MBZ-induced IL-1β release. MBZ-induced IL-1β release was found to be dependent on NLRP3 inflammasome activation and to involve TLR8 stimulation. Finally, MBZ induced tumor-suppressive effects in a coculture model with differentiated THP-1 macrophages and HT29 colon cancer cells. In summary, we report that MBZ induced a pro-inflammatory (M1) phenotype of monocytoid cells, which may, at least partly, explain MBZ's anticancer activity observed in animal tumor models and in the clinic.

Abstract
BACKGROUND Adoptive T-cell therapy offers new options for cancer treatment. Clinical results suggest that T-cell persistence, depending on T-cell memory, improves efficacy. The use of interleukin (IL)-2 for in vitro T-cell expansion is not straightforward because it drives effector T-cell differentiation but does not promote the formation of T-cell memory. We have developed a cost-effective expansion protocol for chimeric antigen receptor (CAR) T cells with an early memory phenotype. METHODS Lymphocytes were transduced with third-generation lentiviral vectors and expanded using CD3/CD28 microbeads. The effects of altering the IL-2 supplementation (0-300 IU/mL) and length of expansion (10-20 days) on the phenotype of the T-cell products were analyzed. RESULTS High IL-2 levels led to a decrease in overall generation of early memory T cells by both decreasing central memory T cells and augmenting effectors. T memory stem cells (TSCM, CD95+CD45RO-CD45RA+CD27+) were present variably during T-cell expansion. However, their presence was not IL-2 dependent but was linked to expansion kinetics. CD19-CAR T cells generated in these conditions displayed in vitro antileukemic activity. In summary, production of CAR T cells without any cytokine supplementation yielded the highest proportion of early memory T cells, provided a 10-fold cell expansion and the cells were functionally potent. DISCUSSION The number of early memory T cells in a T-cell preparation can be increased by simply reducing the amount of IL-2 and limiting the length of T-cell expansion, providing cells with potentially higher in vivo performance. These findings are significant for robust and cost-effective T-cell manufacturing.

Abstract
Cancer immunotherapy is becoming a cornerstone in the clinical care of cancer patients due to the breakthrough trials with immune checkpoint blockade antibodies and chimeric antigen receptor T cells. The next breakthrough in cancer immunotherapy is likely to be oncolytic viruses engineered to selectively kill tumor cells and deceive the immune system to believe that the tumor is a foreign entity that needs to be eradicated. We have developed AdVince, an oncolytic adenovirus for treatment of liver metastases from neuroendocrine tumor (NET). AdVince includes the gene promoter from human chromogranin A for selective replication in neuroendocrine cells, miR122 target sequences for reduced liver toxicity, and a cell-penetrating peptide in the capsid for increased infectivity of tumor cells and optimized spread within tumors. This paper describes the preclinical evaluation of AdVince on freshly isolated human gastrointestinal NET cells resected from liver metastases and freshly isolated human hepatocytes as well as in fresh human blood. AdVince selectively replicates in and kills NET cells. Approximately 73-fold higher concentration of AdVince is needed to induce a similar level of cytotoxicity in NET cells as in hepatocytes. AdVince did not activate complement or induce considerable amount of proinflammatory cytokines or chemokines in human blood. The data presented herein indicate that AdVince can be safely evaluated in a phase I/IIa clinical trial for patients with liver-dominant NET.

Abstract
Background Cancer immunotherapy can be potentiated by conditioning regimens such as cyclophosphamide, which reduces the level of regulatory T cells (tregs). However, myeloid suppressive cells are still remaining. Accordingly to previous reports, gemcitabine improves immune status of cancer patients. In this study, the role of gemcitabine was further explored to map its immunological target cells and molecules in patients with pancreatic cancer. Methods Patient blood was investigated by flow cytometry and cytokine arrays at different time points during gemcitabine treatment. Results The patients had elevated myeloid-derived suppressor cells (MDSCs), and Tregs at diagnosis. Myeloid cells were in general decreased by gemcitabine. The granulocytic MDSCs were significantly reduced while monocytic MDSCs were not affected. In vitro, monocytes responding to IL-6 by STAT3 phosphorylation were prevented to respond in gemcitabine medium. However, gemcitabine could not prevent STAT3 phosphorylation in IL-6-treated tumor cell lines. TGFβ-1 was significantly reduced after only one treatment and continued to decrease. At the same time, the effector T cell:Treg ratio was increased and the effector T cells had full proliferative capacity during the gemcitabine cycle. However, after a resting period, the level of suppressor cells and TGFβ-1 had been restored showing the importance of continuous conditioning. Conclusions Gemcitabine regulates the immune system in patients with pancreatic cancer including MDSCs, Tregs and molecules such as TGFβ-1 but does not hamper the ability of effector lymphocytes to expand to stimuli. Hence, it may be of high interest to use gemcitabine as a conditioning strategy together with immunotherapy.

Abstract
Abstract
Immunotherapy is becoming a cornerstone in cancer treatment of many indications. So far, pancreatic cancer has shown little response to so called checkpoint blockade antibodies. However, animal data suggests that activating immunotherapies releases the effect of checkpoint blockade also in pancreatic cancer. The tumor microenvironment (TEM) supports the growth of the tumor cells and consists of stroma cells, fibroblasts, blood vessels and immune cells. In some tumor lesions, such as those in pancreatic cancer, the TEM is dense and comprises most of the lesion. The TEM regulates immune activity via its high content of M2 macrophages, myeloid derived suppressor cells and T regulatory cells. Further, the dysfunctional blood vessels in lesions are not optimal for recruiting lymphocytes. With these aspects in mind, LOAd703 was developed. LOAd703 is an oncolytic adenovirus carrying TEM modulators.
LOAd703 was constructed from the ICOVIR system of oncolytic adenoviruses in which replication depends on a dysfunctional, hyperphosphorylated retinoblastoma pathway. The genome was further altered by removing E3-6.7K and gp19K, changing the serotype 5 fiber to a serotype 35 fiber to target CD46 expressed by most tumors, as well as by adding a CMV-driven transgene cassette with the human transgenes for TMZ-CD40L and 4-1BBL. Hence, the transgenes will be expressed in both tumor and stroma while oncolysis is initiated in the tumor cells. We demonstrate herein that LOAd703 infection of a panel of pancreatic cancer cell lines efficiently induced tumor cell death within 48-72 hrs post infection while LOAd703 infection of dendritic cells demonstrated an increased maturation of myeloid cells including dendritic cells (DCs). These DCs could in turn potently activate and promote expansion of both T- and NK cells. Further, LOAd703 infection of endothelial cells (HUVEC) induced upregulation of molecules involved in lymphocyte attachment, rolling and transmigration. In conclusion, LOAd703 is a novel oncolytic virus that targets both the tumor and its TME and a clinical trial is underway to elucidate its effect in pancreatic cancer.

Abstract
Bladder cancer is regarded as a promising candidate for innovative therapies in the field of immune and gene therapy. In this paper, we present the subcutaneous, metastatic and a novel orthotopic model of murine MB49 bladder cancer in C57BL/6 mice. We further show the potential of using adenoviral vectors together with different transduction enhancers to augment in vivo gene delivery. Finally, we present candidate genes for tumour detection, therapy or targeting. The MB49 tumour grew rapidly in mice. The subcutaneous model allowed for tumour detection within a week and the possibility to monitor growth rate on a day-by-day basis. Injection of MB49 cells intravenously into the tail vein gave rise to lung metastases within 16 days, while instillation of tumour cells into pretreated bladders led to a survival time of 20–40 days. Adenoviral vectors can be used as a vehicle for gene transfer to the bladder. By far, the most potent transduction enhancer was Clorpactin, also known as oxychlorosene. Last, we show that MB49 cells express tumour-associated antigens like bladder cancer-4, prostate stem cell antigen and six-transmembrane epithelial antigen of the prostate. Given the possibility for efficient genetic modification of the bladder and the presence of known tumour antigens, the MB49 models can be used in innovative ways to explore immunogene therapy.
