Abstract
Abstract
We have developed the use of reovirus as a systemically delivered oncolytic agent in both pre-clinical models and in early Phase clinical trials. Reovirus has direct oncolytic activity against many human/murine tumor cells, partly because of disruption of the PKR-mediated anti-viral response in malignant cells. In addition however, we have shown that anti-tumor therapy is directly associated with immune activation by virus replication in tumors. The immune mechanisms of therapy include both innate immune activation against virally infected tumor cells, as well as the generation of adaptive anti tumor immune responses as a result of in vivo priming against tumor associated antigens released during that killing. Therefore, to exploit the immune components of reovirus anti-tumor therapy, we hypothesized that the combination of reovirus therapy with systemic checkpoint inhibition would augment therapeutic efficacy. To test the hypothesis, we used C57Bl/6 mice, an immune-competent murine model, with established subcutaneous (s.c.) B16 melanomas. In this model, intra-tumoral injection of reovirus into s.c. tumors generated moderate therapy. Provision of systemic anti-PD-1 antibody along with i.t. reovirus, significantly enhanced survival compared to i.t. reovirus alone (p<0.01) and led to >40% of mice being cured long term. Immune analysis suggested that the enhanced therapeutic benefit of reovirus plus checkpoint inhibition is contributed by at least two factors. First, blockade of PD-1 significantly enhanced the ability of NK cells to recognize (TNF-α secretion), and kill, reovirus-infected target tumor cells. Second, anti PD-1 antibody led to a significant reduction in Treg activity in reovirus-treated mice, with the overall effect of increasing the adaptive CD8+ anti-tumor T cell response. Furthermore, in vivo depletion studies demonstrated that NK cells had a dramatic effect in reducing the therapeutic efficacy of reovirus plus anti-PD-1 therapy. Overall, the results indicate that combination therapy of reovirus with PD-1 blockade confers significant survival benefit, by augmenting tumor-specific NK responses and specifically attenuating tumor-specific immunosuppression. These data also suggest that combination of PD-1 inhibition therapy with reovirus oncolytic/immunotherapy represents a readily translatable method to enhance the therapeutic efficacy.

Abstract
Abstract
Background: Coxsackievirus A21 (CVA21) is a naturally occurring “common cold” intercellular adhesion molecule-1 (ICAM-1)-targeted RNA virus. Surface ICAM-1 is up-regulated on a number of cancers including melanoma, non-small cell lung, bladder and prostate cancers. CAVATAK is a novel bio-selected formulation of CVA21, which displays potent oncolytic activity against in vitro cultures of cancer cells and in vivo xenografts of a number of cancers. In this phase I/II study advanced cancer patients received multiple intravenous (IV) doses of CAVATAK to assess treatment tolerance, levels of viral replication and viral-induced immune activation within the tumor micro-environment.
Methods: The phase I/II STORM (Systemic Treatment Of Resistant Malignancies: NCT02043665) study is investigating the tolerance of multiple escalating IV doses of CVA21 in approximately 30 advanced cancer patients. In cohort 1 (n = 3), patients were infused with CVA21 at a dose of 1 × 108 TCID50, in cohort 2 patients (n = 3) were infused with CVA21 at a dose of 3 × 108 TCID50 and treatment of patients in Cohort 3 (n = 12-18) with CVA21 at a dose of 1 × 109 TCID50 has commenced. Tumor biopsies at 8 days following the initial CVA21 infusion are being monitored for levels of virus and markers of potential immune activation. Sequential serum samples are being analyzed for viral loads, kinetics of anti-CVA21 neutralizing antibody (nAb) development and immune system activation via relative serum levels of a panel of immune inflammatory cytokines /immune cell subsets.
Results: To date, multiple CVA21 infusions of patients in Cohorts 1 and 2 have been generally well tolerated. Preliminary data indicate that the prolonged presence of serum CVA21 RNA in some, but not all, patients at times (up to 4 days post-infusion), when complete decay of the administered viral dose was expected; this may indicate possible viral replication within tumor. Such replication in pre-clinical xenograft models was potentially immunogenic, as evidenced by gene expression increases of CXCL-10 and PD-L1. Of particular interest was the finding of comparable kinetics of anti-CVA21 nAb development in patients receiving multiple infusions relative to those administered a single CVA21 infusion during a previous phase I dose-ranging study (NCT00636558). The interim data highlight a robust “multi-dosing-window” in the absence of significant levels of nAb for approximately 7 days post initial viral infusion.
Conclusion: To date, multiple IV infusions in advanced cancer patients have been generally well tolerated. Initial serum viral load data indicate potential tumor-specific CVA21 replication in some patients. Overall, the preliminary data offer an exciting possibly that tumor targeting, infection and immune activation mediated by IV CVA21 may lead to increases in anti-tumor activity, particularly when in future used in combination with immune checkpoint blockade.

Abstract
Reovirus type 3 (Dearing) (RT3D) infection is selective for cells harboring a mutated/activated RAS pathway. Therefore, in a panel of melanoma cell lines (including RAS mutant, BRAF mutant and RAS/BRAF wild-type), we assessed therapeutic combinations that enhance/suppress ERK1/2 signaling through use of BRAF/MEK inhibitors. In RAS mutant cells, the combination of RT3D with the BRAF inhibitor PLX4720 (paradoxically increasing ERK1/2 signaling in this context) did not enhance reoviral cytotoxicity. Instead, and somewhat surprisingly, RT3D and BRAF inhibition led to enhanced cell kill in BRAF mutated cell lines. Likewise, ERK1/2 inhibition, using the MEK inhibitor PD184352, in combination with RT3D resulted in enhanced cell kill in the entire panel. Interestingly, TCID50 assays showed that BRAF and MEK inhibitors did not affect viral replication. Instead, enhanced efficacy was mediated through ER stress-induced apoptosis, induced by the combination of ERK1/2 inhibition and reovirus infection. In vivo, combined treatments of RT3D and PLX4720 showed significantly increased activity in BRAF mutant tumors in both immune-deficient and immune-competent models. These data provide a strong rationale for clinical translation of strategies in which RT3D is combined with BRAF inhibitors (in BRAF mutant melanoma) and/or MEK inhibitors (in BRAF and RAS mutant melanoma).

Abstract
BACKGROUND Oncolytic viral therapy and photodynamic therapy are potential therapies for inoperable or advanced pancreatic cancer. Our aim was to investigate the anti-cancer killing effects of reovirus therapy combined with protoporphyrin IX (PpIX)-mediated photodynamic therapy on a variety of human pancreatic cancer cell lines. METHODS Pancreatic cancer cell lines (PsPC-1 and BXPC-3) and a non-cancer control cell line (HEK293) were infected with reovirus serotype 3 strain Dearing (T3D) at 0, 0·1, 1, and 10 plaque-forming units (PFU) per cell for 48 h. Cells were incubated with PpIX pro-drug 5-aminolevulinic acid (5-ALA) at 0, 1, 2, 3, and 4 mM for 4 h. Then, cells were photo-irradiated for 15 min with visible red light-emitting diodes with a light-fluence of 0·54 J/cm(2) of 653 nm (PpIX optimal excitation wavelength). The killing effects of reovirus combined with PpIX-mediated photodynamic therapy were analysed in methylthiazoltetrazolium (MTT) and trypan blue assays. The effect of adding reovirus after photodynamic therapy was also assessed. The statistical significance of the difference between groups was assessed with the two-tailed Student's t test. p<0·05 was considered statistically significant. FINDINGS Reovirus monotherapy induced cell death in the two pancreatic lines (mean 57% [SE 10·2] at 10 PFU per cell). PpIX-mediated PDT monotherapy induced cell death in a dose-dependent manner (mean 10% [SE 2·2], 30 [6·4], 50 [8·2], and 70 [13·2] after 1, 2, 3, and 4 mM 5-ALA, respectively). Reovirus with PpIX-mediated photodynamic therapy resulted in a significantly increased cytotoxic effect compared with reovirus monotherapy and photodynamic therapy (p=0·042) with 100% cell death observed across pancreatic cell lines with 10 PFU per cell combined with 1 and 2 mM 5-ALA. There was no difference in cytotoxicity observed between added reovirus before or after photodynamic therapy. INTERPRETATION To our knowledge, this is the first in-vitro study to combine reovirus oncolytic viral therapy with PpIX-mediated photodynamic therapy to treat pancreatic cancer. These results show a significant additive effect in cell killing and they provide initial evidence for a novel combined therapeutic intervention. FUNDING National Institute for Health Research.

Abstract
BACKGROUND Paediatric high grade glioma (pHGG) and diffuse intrinsic pontine glioma (DIPG) are highly aggressive brain tumours. Their invasive phenotype contributes to their limited therapeutic response, and novel treatments that block brain tumour invasion are needed. METHODS Here, we examine the migratory characteristics and treatment effect of small molecule glycogen synthase kinase-3 inhibitors, lithium chloride (LiCl) and the indirubin derivative 6-bromoindirubin-oxime (BIO), previously shown to inhibit the migration of adult glioma cells, on two pHGG cell lines (SF188 and KNS42) and one patient-derived DIPG line (HSJD-DIPG-007) using 2D (transwell membrane, immunofluorescence, live cell imaging) and 3D (migration on nanofibre plates and spheroid invasion in collagen) assays. RESULTS All lines were migratory, but there were differences in morphology and migration rates. Both LiCl and BIO reduced migration and instigated cytoskeletal rearrangement of stress fibres and focal adhesions when viewed by immunofluorescence. In the presence of drugs, loss of polarity and differences in cellular movement were observed by live cell imaging. CONCLUSIONS Ours is the first study to demonstrate that it is possible to pharmacologically target migration of paediatric glioma in vitro using LiCl and BIO, and we conclude that these agents and their derivatives warrant further preclinical investigation as potential anti-migratory therapeutics for these devastating tumours.

Abstract
We used a VSV-cDNA library to treat recurrent melanoma, identifying immunogenic antigens, allowing us to target recurrences with immunotherapy or chemotherapy. Primary B16 melanoma tumors were induced to regress by frontline therapy. Mice with recurrent tumors were treated with VSV-cDNA immunotherapy. A Th17 recall response was used to screen the VSV-cDNA library for individual viruses encoding rejection antigens, subsequently targeted using immunotherapy or chemotherapy. Recurrent tumors were effectively treated with a VSV-cDNA library using cDNA from recurrent B16 tumors. Recurrence-associated rejection antigens identified included Topoisomerase-IIα, YB-1, cdc7 kinase, and BRAF. Fourteen out of 16 recurrent tumors carried BRAF mutations (595-605 region) following frontline therapy, even though the parental B16 tumors were BRAF wild type. The emergence of mutated BRAF-containing recurrences served as an excellent target for BRAF-specific immune-(VSV-BRAF), or chemo-(PLX-4720) therapies. Successful PLX-4720 therapy of recurrent tumors was associated with the development of a broad spectrum of T-cell responses. VSV-cDNA technology can be used to identify recurrence specific antigens. Emergence of mutated BRAF may be a major effector of melanoma recurrence which could serve as a target for chemo or immune therapy. This study suggests a rationale for offering patients with initially wild-type BRAF melanomas an additional biopsy to screen for mutant BRAF upon recurrence.

Abstract
Previously, we showed that vesicular stomatitis virus (VSV) engineered to express a cDNA library from human melanoma cells (ASMEL, Altered Self Melanoma Epitope Library) was an effective systemic therapy to treat subcutaneous (s.c.) murine B16 melanomas. Here, we show that intravenous treatment with the same ASMEL VSV-cDNA library was an effective treatment for established intra-cranial (i.c.) melanoma brain tumors. The optimal combination of antigens identified from the ASMEL which treated s.c. B16 tumors (VSV-N-RAS+VSV-CYTC-C+VSV-TYRP-1) was ineffective against i.c. B16 brain tumors. In contrast, combination of VSV-expressed antigens-VSV-HIF-2α+VSV-SOX-10+VSV-C-MYC+VSV-TYRP1-from ASMEL which was highly effective against i.c. B16 brain tumors, had no efficacy against the same tumors growing subcutaneously. Correspondingly, i.c. B16 tumors expressed a HIF-2α(Hi), SOX-10(Hi), c-myc(Hi), TYRP1, N-RAS(lo)Cytc(lo) antigen profile, which differed significantly from the HIF-2α(lo), SOX-10(lo), c-myc(lo), TYRP1, N-RAS(Hi)Cytc(Hi) phenotype of s.c. B16 tumors, and was imposed upon the tumor cells by CD11b(+) cells within the local brain tumor microenvironment. Combining T-cell costimulation with systemic VSV-cDNA treatment, long-term cures of mice with established i.c. tumors were achieved in about 75% of mice. Our data show that the anatomical location of a tumor profoundly affects the profile of antigens that it expresses.

Abstract
The clinical management of cancer continues to be dominated by macroscopic surgical resection, radiotherapy, and cytotoxic drugs. The major challenge facing oncology is to achieve more selective, less toxic and effective methods of targeting disseminated tumors, a challenge oncolytic virotherapy may be well-placed to meet. Characterization of coxsackievirus A21 (CVA21) receptor-based mechanism of virus internalization and lysis in the last decade has suggested promise for CVA21 as a virotherapy against malignancies which overexpress those receptors. Preclinical studies have demonstrated proof of principle, and with the results of early clinical trials awaited, CVA21 may be one of the few viruses to demonstrate benefit for patients. This review outlines the potential of CVA21 as an oncolytic agent, describing the therapeutic development of CVA21 in preclinical studies and early stage clinical trials. Preclinical evidence supports the potential use of CVA21 across a range of malignancies. Malignant melanoma is the most intensively studied cancer, and may represent a “test case” for future development of the virus. Although there are theoretical barriers to the clinical utility of oncolytic viruses like CVA21, whether these will block the efficacy of the virus in clinical practice remains to be established, and is a question which can only be answered by appropriate trials. As these data become available, the rapid journey of CVA21 from animal studies to clinical trials may offer a model for the translation of other oncolytic virotherapies from laboratory to clinic.

Abstract
Viruses that selectively replicate in cancer cells, leading to the death of the cell, are being studied for their potential as cancer therapies. Some of these viruses are naturally occurring but cause little if any illness in humans; others have been engineered to make them specifically able to kill cancer cells while sparing normal cells. These oncolytic viruses may be selective for cancer cells because viral receptors are over-expressed on the surface of cancer cells or because antiviral pathways are distorted in cancer cells. Additionally, when oncolytic viruses kill cancer cells, it can stimulate an antitumour immune response from the host that can enhance efficacy. Numerous early phase trials of at least six oncolytic viruses have been reported with no evidence of concerning toxicity either as single agents or in combination with chemotherapies and radiotherapy. Three oncolytic viruses have reached randomized testing in cancer patients; reolysin in head and neck cancer and JX594 in hepatocellular cancers, while results from the first-phase III trial of T-vec in metastatic melanoma are expected shortly.

Abstract
Aggressive regrowth of recurrent tumors following treatment-induced dormancy represents a major clinical challenge for treatment of malignant disease. We reported previously that recurrent prostate tumors, which underwent complete macroscopic regression followed by aggressive regrowth, could be cured with a vesicular stomatitis virus (VSV)-expressed cDNA library derived from recurrent tumor cells. By screening the protective, recurrence-derived VSV-cDNA library, here we identify topoisomerase-IIα (TOPO-IIα) as a recurrence-specific tumor antigen against which tolerance can be broken. Tumor recurrences, in two different types of tumor (prostate and melanoma), which had evaded two different frontline treatments (immunotherapy or chemotherapy), significantly overexpressed TOPO-IIα compared with their primary tumor counterparts, which conferred a novel sensitivity to doxorubicin (DOX) chemotherapy upon the recurrent tumors. This was exploited in vivo using combination therapies to cure mice, which would otherwise have relapsed, after suboptimal primary therapy in both models. Our data show that recurrent tumors-across histologies and primary treatments-express distinct antigens compared with the primary tumor which can be identified using the VSV-cDNA library technology. These results suggest that it may be possible to design a few common second-line therapies against a variety of tumor recurrences, in some cases using agents with no obvious activity against the primary tumor.

Abstract
We have previously reported that a burst of vascular endothelial growth factor (VEGF) signaling to tumor-associated endothelium induces a proviral state, during which systemically delivered oncolytic reovirus can replicate in endothelium, thereby inducing immune-mediated vascular collapse and significant antitumor therapy. Using chimeric receptors, we show here that induction of the proviral state proceeds through VEGFR2, but not VEGFR1, signaling in endothelial cells. In contrast, innate immune activation by reovirus-exposed endothelial cells was predominantly through VEGFR1. By screening conventional chemotherapies for their ability to induce similar effects in combination with reovirus both in vitro and in vivo, we observed that the proviral state could also be induced in endothelial cells exposed to VEGF during rebound from paclitaxel-mediated inhibition of VEGF signaling. We translated these in vitro findings in vivo by careful scheduling of paclitaxel chemotherapy with systemic virotherapy, neither of which alone had therapeutic effects against B16 tumors. Systemic availability of reovirus during endothelial cell recovery from paclitaxel treatment allowed for endothelial replication of the virus, immune-mediated therapy, and tumor cures. Therefore, careful scheduling of combination viro- and chemotherapies, which preclinical testing suggests are individually ineffective against tumor cells, can lead to rational new clinical protocols for systemic treatments with oncolytic viruses.

Abstract
Background Reovirus type 3 Dearing (T3D) has demonstrated oncolytic activity in vitro, in in vivo murine models and in early clinical trials. However the true potential of oncolytic viruses may only be realized fully in combination with other modalities such as chemotherapy, targeted therapy and radiotherapy. In this study, we examine the oncolytic activity of reovirus T3D and chemotherapeutic agents against human prostate cancer cell lines, with particular focus on the highly metastatic cell line PC3 and the chemotherapeutic agent docetaxel. Docetaxel is the standard of care for metastatic prostate cancer and acts by disrupting the normal process of microtubule assembly and disassembly. Reoviruses have been shown to associate with microtubules and may require this association for efficient viral replication. Methods The effects of reovirus and chemotherapy on in vitro cytotoxicity were investigated in PC3 and Du 145 cells and the interactions between agents were assessed by combination index analysis. An Annexin V/propidium iodide fluorescence-activated cell sorting-based assay was used to determine mode of cell death. The effects of reovirus and docetaxel administered as single agent or combination therapy were tested in vivo in a murine model. The effects of docetaxel and reovirus, alone and together, on microtubule stabilisation were investigated by Western blot analysis. Results Variable degrees of synergistic cytotoxicity were observed in PC3 and Du 145 cells exposed to live reovirus and several chemotherapy agents. Combination of reovirus infection with docetaxel exposure led to increased late apoptotic/necrotic cell populations. Reovirus/docetaxel combined therapy led to reduced tumour growth and increased survival in a PC3 tumour bearing mouse model. Microtubule stabilization was enhanced in PC3 cells treated with reovirus/docetaxel combined therapy compared to other reovirus/chemotherapy combinations. Conclusions The co-administration of a variety of chemotherapeutic agents with live reovirus was able to enhance cytotoxicity synergistically in vitro. The combination of docetaxel with reovirus also delayed tumour growth and improved survival in vivo. Enhanced microtubule stabilisation following this combination treatment may, in part, explain the mechanism of synergy. These results provide evidence to support the ongoing clinical trials using these agents.

Abstract
For the last several decades, the development of antitumor immune-based strategies and the engineering and testing of oncolytic viruses (OVs) has occurred largely in parallel tracks. Indeed, the immune system is often thought of as an impediment to successful oncolytic virus delivery and efficacy. More recently, however, both preclinical and clinical results have revealed potential synergy between these two promising therapeutic strategies. Here, we summarize some of the evidence that supports combining OVs with immuno-therapeutics and suggest new ways to mount a multipronged biological attack against cancers.

Abstract
We have shown that the antitumor activity of vesicular stomatitis virus (VSV) against B16ova tumors in C57BL/6 mice is predominantly due to innate antiviral immune effectors. We have also shown that the innate immune-activating properties of VSV can be harnessed to prime adaptive T-cell responses against a tumor-associated antigen (TAA) if the virus is engineered to express the cDNA of the antigen. Here, we show that the combination of VSV expressing OVA as a model tumor antigen, along with adoptive T-cell therapy targeted against the same antigen, is superior to either treatment alone and induces systemic antitumor activity. In addition, we extend our findings with the OVA model to the therapeutic use of VSV expressing hgp100, a self TAA against which tolerance is well established in C57BL/6 mice. In contrast to VSV-ova, T-cell responses raised by VSV-hgp100 were insufficient to improve therapy against B16ova tumors compared with VSV-GFP alone. However, in combination with adoptive transfer of gp100-specific pmel T cells, intratumoral VSV-hgp100 cured significantly more mice than either virus or T cells alone. Even in an aggressive model of metastatic disease, antitumor therapy was generated at levels similar to those observed in the VSV-ova/OT-I model in which a potently immunogenic, nonself TAA was targeted. Therefore, individual poorly effective virotherapies and T-cell therapies that target self TAA of low immunogenicity, which reflects the situation in patients, can be combined to generate very effective antitumor therapy.

Abstract
Background As well as inducing direct oncolysis, reovirus treatment of melanoma is associated with activation of innate and adaptive anti-tumour immune responses. Results Here we characterise the effects of conditioned media from reovirus-infected, dying human melanoma cells (reoTCM), in the absence of live virus, to address the immune bystander potential of reovirus therapy. In addition to RANTES, IL-8, MIP-1α and MIP-1β, reovirus-infected melanoma cells secreted eotaxin, IP-10 and the type 1 interferon IFN-β. To address the mechanisms responsible for the inflammatory composition of reoTCM, we show that IL-8 and IFN-β secretion by reovirus-infected melanoma cells was associated with activation of NF-κB and decreased by pre-treatment with small molecule inhibitors of NF-κB and PKR; specific siRNA-mediated knockdown further confirmed a role for PKR. This pro-inflammatory milieu induced a chemotactic response in isolated natural killer (NK) cells, dendritic cells (DC) and anti-melanoma cytotoxic T cells (CTL). Following culture in reoTCM, NK cells upregulated CD69 expression and acquired greater lytic potential against tumour targets. Furthermore, melanoma cell-loaded DC cultured in reoTCM were more effective at priming adaptive anti-tumour immunity. Conclusions These data demonstrate that the PKR- and NF-κB-dependent induction of pro-inflammatory molecules that accompanies reovirus-mediated killing can recruit and activate innate and adaptive effector cells, thus potentially altering the tumour microenvironment to support bystander immune-mediated therapy as well as direct viral oncolysis.

Abstract
Despite having potent oncolytic activity, in vitro, direct intratumoral injection of oncolytic vesicular stomatitis virus (VSV) into established AE17ova mesothelioma tumors in C57Bl/6 mice had no therapeutic effect. During studies to combine systemic cyclophosphamide (CPA) with VSV to suppress the innate immune reaction against VSV, we observed that CPA alone had highly significant antitumor effects in this model. However, against our expectations, the combination of CPA and VSV consistently reduced therapeutic efficacy compared to CPA alone, despite the fact that the combination increased intratumoral VSV titers. We show here that CPA-mediated therapy against AE17ova tumors was immune-mediated and dependent upon both CD4 T cells and natural killer (NK) cells. However, intratumoral VSV induced a transforming growth factor-β (TGF-β)-dependent suppressive activity, mediated by CD11b(+)GR-1(+) cells that significantly inhibited both antigen-specific T-cell activation, and CPA-activated, NK-dependent killing of AE17ova tumor cells. Overall, our results show that treatment with oncolytic viruses can induce a variety of immune-mediated consequences in vivo with both positive, or negative, effects on antitumor therapy. These underexplored immune consequences of treatment with oncolytic viruses may have significant, and possibly unexpected, impacts on how virotherapy interacts in combination with other agents which modulate antitumor immune effectors.

Abstract
We show here, for the first time to our knowledge, that the antitumor therapy of oncolytic vesicular stomatitis virus (VSV) in the B16ova model depends upon signaling through myeloid differentiation primary response gene 88 (MyD88) in host cells. VSV-mediated therapy of B16ova tumors was abolished in MyD88(-/-) mice despite generation of antigen-specific T cell responses similar to those in immune-competent mice. Mice defective in only toll-like receptor 4 (TLR4), TLR7, or interleukin 1 (IL-1) signaling retained VSV-induced therapy, suggesting that multiple, redundant pathways of innate immune activation by the virus contribute to antitumor immune reactivity. Lack of MyD88 signaling was associated with decreased expression of proinflammatory cytokines and neutrophil infiltration in response to intratumoral virus, as well as decreased infiltration of draining lymph nodes (LN) with plasmacytoid dendritic cells (pDCs) (CD11b(-)GR1(+)B220(+)) and myeloid-derived suppressor cells (CD11b(+)GR1(+)F4/80(+)). MyD88 signaling in response to VSV was also closely associated with a type I interferon (IFN) response. This inhibited virus replication within the tumor but also protected the host from viral dissemination from the tumor. Therefore, the innate immune response to oncolytic viruses can be, simultaneously, protherapeutic, antioncolytic, and systemically protective. These paradoxically conflicting roles need to be carefully considered in future strategies designed to improve the efficacy of oncolytic virotherapy.

Abstract
PURPOSE REOLYSIN (Oncolytics Biotech) consists of a wild-type oncolytic reovirus, which has selective cytotoxicity for tumor cells while sparing normal cells. In a phase I study as a single agent, repeated infusions of reovirus were safe with evidence of antitumor activity. Preclinical studies indicate potential for synergy between reovirus and chemotherapeutic agents. A multicenter, phase I dose escalation study was designed to assess the safety of combining reovirus with docetaxel chemotherapy in patients with advanced cancer. EXPERIMENTAL DESIGN Patients received 75 mg/m(2) docetaxel (day 1) and escalating doses of reovirus up to 3 × 10(10) TCID(50) (days 1-5) every 3 weeks. RESULTS Twenty-five patients were enrolled, and 24 patients were exposed to treatment, with 23 completing at least one cycle and 16 suitable for response assessment. Dose-limiting toxicity of grade 4 neutropenia was seen in one patient, but the maximum tolerated dose was not reached. Antitumor activity was seen with one complete response and three partial responses. A disease control rate (combined complete response, partial response, and stable disease) of 88% was observed. Immunohistochemical analysis of reovirus protein expression was observed in posttreatment tumor biopsies from three patients. CONCLUSION The combination of reovirus and docetaxel is safe, with evidence of objective disease response, and warrants further evaluation in a phase II study at a recommended schedule of docetaxel (75 mg/m(2), three times weekly) and reovirus (3 × 10(10) TCID(50), days 1-5, every 3 weeks).

Abstract
The potential for increased sensitivity of tumor cells to oncolytic reovirus by altering the normal cell cycle using clinically available pharmacological agents was investigated. B16.F10 mouse melanoma cells were partially synchronized with hydroxyurea, thymidine, or by mitotic shake-off. Cell survival was determined using MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)- 2-(4-sulfophenyl)-2H-tetrazolium)] survival assay and virus yield in tumors by plaque assay. An enhanced sensitivity to reovirus was observed following the removal of either hydroxyurea or thymidine from the culture medium (P < 0.0001). The greatest survival difference compared to normal cycling cells was noted when the majority of cells were in S and G2/M phases, and was associated with increased viral replication. Cells collected by mitotic shake-off were nearly devoid of cells in S phase and were less susceptible to reovirus-induced cell kill than their nonsynchronized counterparts (P < 0.0001). In vivo combination of hydroxyurea followed by intratumoral reovirus resulted in reduced tumor growth and increased survival compared to monotherapy (P = 0.0041) at 15 days. Increased amounts of virus were retrieved from tumors from mice treated with sequential hydroxyurea/reovirus compared to concomitant treatment or reovirus monotherapy. These data justify clinical evaluation of this approach supported by the extensive experience, low cost, simple administration, and availability of hydroxyurea.

Abstract
Oncolytic virotherapy can be achieved in two ways: (1) by exploiting an innate ability of certain viruses to selectively replicate in tumor tissues, and (2) by using viruses to deliver toxic or immunostimulatory genes to tumors. Vesicular stomatitis virus (VSV) selectively replicates in tumors lacking adequate type I interferon response. The efficacy of oncolytic virotherapy using VSV against B16 melanomas in C57BL/6 mice is dependent on CD8(+) T and natural killer cells. Because immunotherapies that prime specific CD8(+) T cells against melanocyte/melanoma antigens can generate significant therapeutic responses, we hypothesized that engineering VSV to express the potent T cell costimulatory molecule CD40 ligand (VSV-CD40L) would enhance virotherapy with concomitant priming of melanoma-specific T cells. However, we observed no difference in antitumor efficacy between the parental VSV-GFP and VSV-CD40L. In contrast, intratumoral injection of a replication-defective adenovirus expressing CD40L (Ad-CD40L) consistently produced significantly greater therapy than either replication-competent VSV-GFP or VSV-CD40L. The Ad-CD40L-mediated tumor regressions were associated with specific T cell responses against tumor-associated antigens (TAAs), which took several days to develop, whereas VSV-CD40L rapidly induced high levels of T cell activation without specificity for TAAs. These data suggest that the high levels of VSV-associated immunogenicity distracted immune responses away from priming of tumor-specific T cells, even in the presence of potent costimulatory signals. In contrast, a replication-defective Ad-CD40L allowed significant priming of T cells directed against TAAs. These observations suggest that an efficiently primed antitumor T cell response can produce similar, if not better, therapy against an established melanoma compared with intratumoral injection of a replication-competent oncolytic virus.

Abstract
The sodium iodide symporter (NIS) is responsible for thyroidal, salivary, gastric, intestinal and mammary iodide uptake. It was first cloned from the rat in 1996 and shortly thereafter from human and mouse tissue. In the intervening years, we have learned a great deal about the biology of NIS. Detailed knowledge of its genomic structure, transcriptional and post-transcriptional regulation and pharmacological modulation has underpinned the selection of NIS as an exciting approach for targeted gene delivery. A number of in vitro and in vivo studies have demonstrated the potential of using NIS gene therapy as a means of delivering highly conformal radiation doses selectively to tumours. This strategy is particularly attractive because it can be used with both diagnostic (99mTc, 125I, 124I)) and therapeutic (131I, 186Re, 188Re, 211At) radioisotopes and it lends itself to incorporation with standard treatment modalities, such as radiotherapy or chemoradiotherapy. In this article, we review the biology of NIS and discuss its development for gene therapy.

Abstract
Innate immune effector mechanisms triggered by oncolytic viruses may contribute to the clearance of both infected and uninfected tumor cells in immunocompetent murine hosts. Here, we developed an in vitro tumor cell/bone marrow coculture assay and used it to dissect innate immune sensor and effector responses to intratumoral vesicular stomatitis virus (VSV). We found that the type III IFN interleukin-28 (IL-28) was induced by viral activation of innate immune-sensing cells, acting as a key mediator of VSV-mediated virotherapy of B16ova melanomas. Using tumor variants which differentially express the IL-28 receptor, we showed that IL-28 induced by VSV within the tumor microenvironment sensitizes tumor cells to natural killer cell recognition and activation. These results revealed new insights into the immunovirological mechanisms associated with oncolytic virotherapy in immune-competent hosts. Moreover, they defined a new class of tumor-associated mutation, such as acquired loss of responsiveness to IL-28 signaling, which confers insensitivity to oncolytic virotherapy through a mechanism independent of viral replication in vitro. Lastly, the findings suggested new strategies to manipulate immune signals that may enhance viral replication, along with antitumor immune activation, and improve the efficacy of oncolytic virotherapies.

Abstract
Viral therapy of cancer includes strategies such as viral transduction of tumour cells with 'suicide genes', using viral infection to trigger immune-mediated tumour cell death and using oncolytic viruses for their direct anti-tumour action. However, problems still remain in terms of adequate viral delivery to tumours. A role is also emerging for single-organ isolation and perfusion. Having begun with the advent of isolated limb perfusion for extremity malignancy, experimental systems have been developed for the perfusion of other organs, particularly the liver, kidneys and lungs. These are beginning to be adopted into clinical treatment pathways. The combination of these two modalities is potentially significant. Locoregional perfusion increases the exposure of tumour cells to viral agents. In addition, the avoidance of systemic elimination through the immune and reticulo-endothelial systems should provide a mechanism for increased transduction/infection of target cells. The translation of laboratory research to clinical practice would occur within the context of perfusion programmes, which are already established in the clinic. Many of these programmes include the use of vasoactive cytokines such as tumour necrosis factor-alpha, which may have an effect on viral uptake. Evidence of activation of specific anti-tumour immunological responses by intratumoural and other existing methods of viral administration raises the intriguing possibility of a locoregional therapy, with the ability to affect distant sites of disease. In this review, we examined the state of the literature in this area and summarized current findings before indicating likely areas of continuing interest.

Abstract
Clinical trials of oncolytic virotherapy have shown low toxicity and encouraging signs of efficacy. However, it remains critically important to develop methods for systemic viral delivery if such therapies are to be clinically implemented to treat established tumors. In this respect, much effort is being focused on combining oncolytic viruses with standard treatment modalities such as inhibitors of VEGF165 (an alternatively spliced isoform of VEGF-A) signaling, which are widely used to treat several different cancers. Here, we have demonstrated that combining VEGF165 inhibitors with systemic delivery of oncolytic viruses leads to substantial regression and cure of established tumors in immunocompetent mice. We have shown that manipulating VEGF165-mediated signaling by administering VEGF165 to mice harboring mouse melanoma cells that do not express VEGF165 and by administering a VEGF inhibitor and then withdrawing treatment to allow VEGF levels to rebound in mice harboring mouse melanoma cells expressing VEGF165 allows tumor-associated endothelial cells transiently to support viral replication. This approach led to direct tumor cell lysis and triggered innate immune-mediated attack on the tumor vasculature. It also resulted in long-term antitumor effects, even against tumors in which viral replication is poorly supported. Since this combinatorial approach targets the tumor endothelium, we believe these data have direct, wide-ranging, and immediate clinical applicability across a broad range of tumor types.

Abstract
BACKGROUND The potential utility of dendritic cells (DC) as cancer vaccines has been established in early trials in human cancers. The concomitant administration of cytotoxic agents and DC vaccines has been previously avoided due to potential immune suppression by chemotherapeutics. Recent studies show that common chemotherapy agents positively influence adaptive and innate anti-tumour immune responses. RESULTS We investigated the effects of paclitaxel on human DC biology in vitro. DCs appear to sustain a significant level of resistance to paclitaxel and maintain normal viability at concentrations of up to 100 micromol. In some cases this resistance against paclitaxel is significantly better than the level seen in tumour cell lines. Paclitaxel exposure led to a dose dependent increase in HLA class II expression equivalent to exposure to lipopolysaccharide (LPS), and a corresponding increase in proliferation of allogeneic T cells at the clinically relevant doses of paclitaxel. Increase in HLA-Class II expression induced by paclitaxel was not blocked by anti TLR-4 antibody. However, paclitaxel exposure reduced the endocytic capacity of DC but reduced the expression of key pro-inflammatory cytokines such as IL-12 and TNFalpha. Key morphological changes occurred when immature DC were cultured with 100 micromol paclitaxel. They became small rounded cells with stable microtubules, whereas there were little effects on LPS-matured DC. CONCLUSIONS The effect of paclitaxel on human monocyte derived DC is complex, but in the clinical context of patients receiving preloaded and matured DC vaccines, its immunostimulatory potential and resistance to direct cytotoxicity by paclitaxel would indicate potential advantages to co-administration with vaccines.

Abstract
It is time for those working on oncolytic viruses to take stock of the status of the field. We now have at our disposal an array of potential therapeutic agents, and are beginning to conduct early-phase clinical trials in patients with relapsed/metastatic cancers. By drawing on lessons learned during the development of other biological therapies, such as monoclonal antibodies and targeted small molecule inhibitors, we are now in a position to chart the course of the next wave of trials that will go beyond the phase I studies of safety and feasibility. In this article we review our approach to the development of oncolytic viruses as cancer therapeutics. In doing so, we emphasise the fact that this process is modular and involves multiple iterative steps between the laboratory and the clinic. Ultimately, at least in the medium term, the future of oncolytic virotherapy lies in combination regimens with standard anti-cancer agents such as radiation and chemotherapy.

Abstract
Abstract
Background: Reovirus is a double-stranded RNA virus which replicates in cells with activated Ras signaling pathway, while sparing normal cells. Following our recent study of intravenous (i.v.) reovirus in patients with advanced malignancies1, we have conducted a Phase I/II dose escalation study of i.v. reovirus in combination with chemotherapy.
Methods: REOLYSIN® was administered to cohorts of 3 patients in escalating doses (3 × 109, 1 × 1010, 3 × 1010 TCID50) on days 1–5 while carboplatin AUC 5 and paclitaxel 175 mg/m2 were administered on day 1 of a 3-weekly schedule. Eligible patients had good performance status (ECOG PS: 0–2) with advanced cancers which were not amenable to curative treatment or were refractory to standard therapy for which paclitaxel/carboplatin was appropriate palliative chemotherapy.
Results: Twenty-three patients (15 males, median age 56.9 years) with head and neck cancer (n=17), melanoma (n=4) or peritoneal/endometrial cancer (n=2) received 106 cycles (median 6, range 1–8) of combination treatment. In the dose-escalation phase of the study, there were no dose-limiting toxicities. Grade 3/4 toxicities included anaemia, leucopenia, neutropenia, lymphopenia, thrombocytopenia, infection and hypotension. Viral shedding (as assayed by reverse transcription PCR) has been documented in 2 patients. Neutralising anti-reovirus antibody responses have been measured using a previously reported technique2 and will be presented.
In the Phase 1 study partial responses (PR) were noted in one of four patients with melanoma and in two of five patients with head and neck cancer. An expanded cohort of head and neck cancer patients was therefore treated at the maximum dose level (3 × 1010 TCID50) in order to further assess tumor response in this setting.
To date, 14 patients with head and neck cancer have received at least two cycles and are evaluable for response. Most of them were refractory to previous platinum-based chemotherapy for recurrent/metastatic disease. PR was seen in 6 patients (43%), SD in 5 (36%) and PD in 3 (21%). The study is ongoing.
Conclusion: Intravenous administration of reovirus in combination with carboplatin/paclitaxel is a safe and well-tolerated combination with promising anticancer activity in SCCHN. Further evaluation of this combination in a randomized Phase III trial in SCCHN is planned.

Abstract
PURPOSE To test combination treatment schedules of reovirus and cisplatin chemotherapy in human and murine melanoma cell lines and murine models of melanoma and to investigate the possible mechanisms of synergistic antitumor effects. EXPERIMENTAL DESIGN The effects of reovirus +/- chemotherapy on in vitro cytotoxicity and viral replication were assessed using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay and plaque assay. Interactions between agents were assessed by combination index analysis. Mode of cell death was assessed by Annexin V/propidium iodide fluorescence-activated cell sorting-based assays; gene expression profiling of single versus combination treatments was completed using the Agilent microarray system. Single agent and combination therapy effects were tested in vivo in two immunocompetent models of murine melanoma. RESULTS Variable degrees of synergistic cytotoxicity between live reovirus and several chemotherapy agents were observed in B16.F10 mouse melanoma cells, most significantly with cisplatin (combination index of 0.42 +/- 0.03 at ED(50)). Combination of cisplatin and reovirus exposure led to increased late apoptotic/necrotic cell populations. Cisplatin almost completely abrogated the inflammatory cytokine gene up-regulation induced by reovirus. Combination therapy led to significantly delayed tumor growth and improved survival in vivo (P < 0.0001 and P = 0.0003, respectively). Cisplatin had no effect on the humoral response to reovirus in mice. However, cisplatin treatment suppressed the cytokine and chemokine response to reovirus in vitro and in vivo. CONCLUSION The combination of reovirus and several chemotherapeutic agents synergistically enhanced cytotoxicity in human and murine melanoma cell lines in vitro and murine tumors in vivo. The data support the current reovirus/chemotherapy combination phase I clinical studies currently ongoing in the clinic.

Abstract
We have a long-term interest in the connectivity between autoimmunity and tumor rejection. However, outside of the melanocyte/melanoma paradigm, little is known about whether autoimmune responses to normal tissue can induce rejection of tumors of the same histologic type. Here, we induced direct, pathogen-like cytotoxicity to the normal pancreas in association with the immune adjuvant heat shock protein 70. In sharp contrast to our studies with a similar approach for the treatment of prostate cancer, inflammatory killing of the normal pancreas induced a Th1-like, anti-self-response to pancreatic antigens, which was rapidly suppressed by a concomitant suppressive regulatory T cell (Treg) response. Interestingly, even when Treg cells were depleted, the Th1-like response was insufficient to induce significant ongoing autoimmunity. However, the Th1-like response to antigens expressed in the pancreas at the time of damage was sufficient to induce rejection of tumors expressing either a foreign (ova) antigen or fully syngeneic tumor antigens (on Panc02 tumor cells), provided that Treg were depleted before inflammatory killing of the normal pancreas. Taken together, these data indicate that profound differences exist between the immunoprotective mechanisms in place between different tissues (pancreas and prostate) in their response to pathogen-like damage. Moreover, they also show that, although multiple layers of immunologic safeguards are in place to prevent the development of severe autoimmune consequences in the pancreas (in contrast to the prostate), tumor rejection responses can still be decoupled from pathologic autoimmune responses in vivo, which may provide novel insights into the immunotherapeutic treatment of pancreatic cancer.

Abstract
Oncolytic viruses delivered directly into the circulation face many hazards that impede their localization to, and infection of, metastatic tumors. Such barriers to systemic delivery could be overcome if couriers, which confer both protection, and tumor localization, to their viral cargoes, could be found. Several preclincal studies have shown that viruses can be loaded into, or onto, different types of cells without losing the biological activity of either virus or cell carrier. Importantly, such loading can significantly protect the viruses from immune-mediated virus-neutralizing activities, including antiviral antibody. Moreover, an impressive portfolio of cellular vehicles, which have some degree of tropism for tumor cells themselves, or for the biological properties associated with the tumor stroma, is already available. Therefore, it will soon be possible to initiate clinical protocols to test the hypopthesis that cell-mediated delivery can permit efficient shipping of oncolytic viruses from the loading bay (the production laboratory) directly to the tumor in immune-competent patients with metastatic disease.

Abstract
PURPOSE The goals of this study were (a) to investigate whether preconditioning of immunocompetent mice with PC-61-mediated regulatory T-cell (Treg) depletion and interleukin-2 (IL-2) would enhance systemic delivery of reovirus into subcutaneous tumors and (b) to test whether cyclophosphamide (CPA), which is clinically approved, could mimic PC-61 for modification of Treg activity for translation into the next generation of clinical trials for intravenous delivery of reovirus. EXPERIMENTAL DESIGN C57Bl/6 mice bearing subcutaneous B16 tumors were treated with CPA or PC-61 followed by 10 injections of low-dose IL-2. Mice were then treated with intravenous reovirus. Virus localization to tumor and other organs was measured along with tumor growth and systemic toxicity. RESULTS Preconditioning with PC-61 and IL-2 enhanced localization of intravenous oncolytic reovirus to tumors with significantly increased antitumor therapy compared with controls (P < 0.01). However, with the maximal achievable dose of reovirus, Treg modification + IL-2 was also associated with systemic toxicity. CPA (100 mg/kg) did not deplete, but did functionally inhibit, Treg. CPA also mimicked PC-61, in combination with IL-2, by inducing "hyperactivated" NK cells. Consistent with this, preconditioning with CPA + IL-2 enhanced therapy of intravenously delivered, intermediate-dose reovirus to a level indistinguishable from that induced by PC-61 + IL-2, without any detectable toxicity. CONCLUSION With careful reference to ongoing clinical trials with dose escalation of reovirus alone and in combination with CPA, we propose that future clinical trials of CPA + IL-2 + reovirus will allow for both improved levels of virus delivery and increased antitumor efficacy.

Abstract
e14519 Background: Reolysin, a wild type reovirus (Dearing strain), replicates preferentially in Ras-activated cancer cells. Preclinical data have demonstrated synergistic tumor kill when reolysin is combined with standard chemotherapies including platinum agents and taxanes, justifying the clinical evaluation of this drug combination. Methods: Pts were initially treated in an open-label, dose-escalating, phase I trial and received iv reolysin, d1–5, iv carboplatin (AUC5), d1, and paclitaxel (175mg/m2), d1, qw3. Reolysin was administered at a starting dose of 3x109 TCID50 and then increased to 1x1010 and 3x1010 TCID50 in cohorts of 3 pts. Primary endpoints for the dose escalation trial were to determine the maximum tolerated dose, dose limiting toxicity (DLT) and to recommend a dose for phase II studies. Secondary endpoints were to evaluate pharmacokinetics, immune response and anti-tumour activity. The primary endpoint for the phase II expansion cohort in head and neck (H&N) pts is to characterize response rate. Results: 17 heavily pre-treated pts (11 M, median age 55 yrs) with advanced cancer: H&N (10), melanoma (4), peritoneal/endometrial cancer (2), and sarcoma (1) have received 82 cycles of treatment to date; 4 pts are still on study. There were no DLTs in the dose escalation. Toxicities were mainly grade 1 and 2 and included: nausea, fatigue, vomiting, myalgia, fever, neutropenia, lymphopenia, thrombocytopenia and hypotension. This combination resulted in a blunting of antiviral immune response as compared to monotherapy virus. Response rates in 15 evaluable patients were partial response (PR) (4 pts), stable disease (SD) (6 pts) and progressive disease (5 pts). Of note, all PRs and 4/5 SDs were in H&N disease. Conclusions: The combination of reolysin and carboplatin/paclitaxel was well tolerated and resulted in disease control in the majority of pts. Significant responses in refractory H&N pts recommended this combination for phase II evaluation. Enrollment is ongoing and randomized studies are planned. [Table: see text]

Abstract
e14514 Background: Reolysin, a wild type reovirus serotype 3 Dearing strain, replicates preferentially in Ras-activated cancer cells. In vitro and in vivo data have shown that combining reolysin and radiation (RT) significantly increases RT-induced cytotoxicity. A completed phase I trial of ITu reolysin and RT demonstrated that the combination was well tolerated and resulted in local and systemic responses. Methods: This open-label, single-arm, multicenter Phase 2 study combined ITu reolysin with low-dose fractionated RT. 20 Gy was given in 5 consecutive daily 4 Gy fractions combined with 2 ITu injections of reolysin (1x1010 TCID50) on days 2 & 4. The primary endpoint was objective tumor response rate in treated lesions. Secondary endpoints were to evaluate: viral replication, immune response and safety. Pts with ECOG performance status ≤2, with refractory advanced or metastatic cancers were eligible. Results: 16 heavily pre-treated pts (9 male, median age 66 yrs, ECOG 0:4pts; 1:12pts) with advanced cancer: melanoma (5), colorectal (4), gastric (1), ovarian (1), pancreas (1), lung (1), cholangiocarcinoma (1), sinus (1), and thyroid (1) were enrolled since Dec 2006. Most pts had received prior chemotherapy (13 pts) or RT (5 pts). No related serious adverse effects were observed during the study. Toxicities related to treatment were Grade 1 or 2: chills, pyrexia, headache, lethargy, anorexia, vomiting, shivering, nausea, and mild injection site pain. Of 14 pts evaluable for response, 13 pts had stable disease or better in the treated target lesion. Of these, partial responses were observed in 4 pts (lung, melanoma x 2, gastric) and minor responses were observed in 2 pts (thyroid, ovarian). Antibody responses to reolysin were delayed compared to previous results with intravenous administration. Conclusions: The combination of ITu reolysin and low dose RT was well tolerated and resulted in marked responses or stabilization in the treated target lesions for most of the pts evaluated to date. Further study in the radical setting is warranted. [Table: see text]

Abstract
BACKGROUND AND PURPOSE Standard treatment for rectal cancer which threatens the expected plane of resection on MRI imaging is long-course, pre-operative chemoradiotherapy (1.8-2Gy, 25-28 fractions). Not all patients are suitable for this because of age, poor performance status or co-morbidities. We describe our experience of short-course (5x5Gy) pre-operative radiotherapy with planned, delayed surgery (SCPRT-delay) in this patient group. MATERIALS AND METHODS Between April 2001 and October 2007, 43 patients were selected for SCPRT-delay. The clinical records were retrospectively evaluated. RESULTS Median age was 82 (range 58-87). Forty-one patients had radiotherapy of which 26 (61%) were subsequently able to have surgery. Of these, R0, R1 and R2 resections were performed in 22, 2 and 2 patients, respectively. Treatment was well tolerated, although two patients required hospital admission for management of diarrhoea and one developed significant late small bowel toxicity, attributable to radiotherapy. In those undergoing R0 or R1 resection there have been no local recurrences (median follow-up 18 months). Median survival for the whole group was 23 months, although this was 44 months in those undergoing surgery. CONCLUSIONS SCPRT-delay appears to be a useful alternative to long-course pre-operative chemoradiotherapy in this high-risk group of patients.

Abstract
PURPOSE To determine the safety and feasibility of daily i.v. administration of wild-type oncolytic reovirus (type 3 Dearing) to patients with advanced cancer, assess viral excretion kinetics and antiviral immune responses, identify tumor localization and replication, and describe antitumor activity. EXPERIMENTAL DESIGN Patients received escalating doses of reovirus up to 3 x 10(10) TCID(50) for 5 consecutive days every 4 weeks. Viral excretion was assessed by reverse transcription-PCR and antibody response by cytotoxicity neutralization assay. Pretreatment and post-treatment tumor biopsies were obtained to measure viral uptake and replication. RESULTS Thirty-three patients received 76 courses of reovirus from 1 x 10(8) for 1 day up to 3 x 10(10) TCID(50) for 5 days, repeated every four weeks. Dose-limiting toxicity was not seen. Common grade 1 to 2 toxicities included fever, fatigue, and headache, which were dose and cycle independent. Viral excretion at day 15 was not detected by reverse transcription-PCR at 25 cycles and only in 5 patients at 35 cycles. Neutralizing antibodies were detected in all patients and peaked at 4 weeks. Viral localization and replication in tumor biopsies were confirmed in 3 patients. Antitumor activity was seen by radiologic and tumor marker (carcinoembryonic antigen, CA19.9, and prostate-specific antigen) evaluation. CONCLUSIONS Oncolytic reovirus can be safely and repeatedly administered by i.v. injection at doses up to 3 x 10(10) TCID(50) for 5 days every 4 weeks without evidence of severe toxicities. Productive reoviral infection of metastatic tumor deposits was confirmed. Reovirus is a safe agent that warrants further evaluation in phase II studies.
