Abstract
Administration of oncolytic viruses (OVs) is an emerging anticancer strategy that exploits the lytic nature of viral replication to enhance the killing of malignant cells. OVs can be used as tools to directly induce cancer cell death and to trigger local and/or systemic immune responses to metastatic cancer in vivo. The effectiveness of OV therapy was initially highlighted by the clinical use of the genetically modified herpes virus, talimogene laherparepvec, for melanoma therapy. A number of OVs are now being evaluated as potential treatments for cancer in clinical trials. In spite of being engineered to specifically target tumor cells, the safety and off-target effects of OV therapy are a concern. The potential safety concerns of OVs are highlighted by current clinical trial criteria, which exclude individuals harbouring other viral infections and people who are immunocompromised. Despite the potential for adverse effects, clinical trials to date revealed relatively minimal adverse immune-related effects, such as fever. With advances in our understanding of virus replication cycles, several novel OVs have emerged. Reverse genetic systems have facilitated the insertion of anticancer genes into a range of OVs to further enhance their tumor-killing capacity. In this review, we highlight the recent advances in OV therapy for a range of human cancers in in vitro and in in vivo animal studies. We further discuss the future of OVs as a therapeutic strategy for a range of life-threatening cancers.

Abstract
Talimogene laherparepvec (T‐VEC) is a intralesional oncolytic virotherapy, licensed in the European Union for locoregional advanced melanoma of American Joint Committee on Cancer stages IIIB, IIIC and IVM1a. Organ transplant recipients are currently excluded from all clinical trials dealing with immunotherapies due to the risk of transplant rejection. A 58‐year‐old white man with a history of heart and kidney transplantation in 2014 was diagnosed with melanoma (Breslow thickness 1·6 mm, stage pT2a) on the left arm in September 2015. In March 2016 he developed in transit metastases, and local therapy with a combination of topical imiquimod (5%) and cryotherapy of individual lesions was initiated. However, in November 2016 therapy was stopped following local progression of the metastases. An interdisciplinary decision to treat the patient with T‐VEC was taken. After 11 cycles of T‐VEC, the patient showed a complete response. As of June 2018, 11 months after the last treatment cycle of T‐VEC, the patient continues to be tumour free. The patient tolerated the therapy well with only mild adverse events and did not show any sign of graft rejection or loss of function of the transplanted organs. We conclude that T‐VEC can be a potentially effective and safe treatment in patients with a history of organ transplantation. Nevertheless, due to this special situation, the risks and benefits should always be discussed with an interdisciplinary tumour board. What's already known about this topic? Talimogene laherparepvec (T‐VEC) is a intralesional oncolytic virotherapy, licensed in the European Union for locoregional advanced melanoma of American Joint Committee on Cancer stages IIIB, IIIC and IVM1a. Organ transplant recipients have so far been excluded from all clinical trials dealing with immunotherapies due to the risk of transplant rejection.
What does this study add? We conclude that T‐VEC can be a potentially effective and safe treatment in patients with a history of organ transplantation. Nevertheless, due to this special situation, the risks and benefits should always be discussed with an interdisciplinary tumour board.

Abstract
Talimogene laherparepvec is an oncolytic virus recently approved for targeted treatment of advanced melanoma. Because of an inflammatory reaction, treated lesions may increase in size and develop infiltrative margins that can be construed as disease progression or extracapsular spread. In this report, we describe our initial experience imaging the response of metastatic nodes injected with talimogene laherparepvec. Six of 12 nodes (50%) showed growth from baseline followed by decreased size, 5 of 12 nodes (42%) showed a downward size trend, and 1 node showed continued increase in size. Seven of 9 nodes (78%) developed infiltrative margins at a median of 79 days, and 6 of 9 (67%) nodes became necrotic at a median of 76 days after injection, all showing decreased size at final follow-up. An increase in the size of nodes injected with talimogene laherparepvec does not necessarily indicate progression. Infiltrative margins are also frequently seen and may be confused with extracapsular disease.

Abstract
Neuregulin (NRG), an epidermal growth factor is known to promote the growth of various cell types, including human melanoma cells through ErbB family of tyrosine kinases receptors. Tanapoxvirus (TPV)-encoded protein TPV-15L, a functional mimic of NRG, also acts through ErbB receptors. Here, we show that the TPV-15L protein promotes melanoma proliferation. TPV recombinant generated by deleting the 15L gene (TPVΔ15L) showed replication ability similar to that of wild-type TPV (wtTPV) in owl monkey kidney cells, human lung fibroblast (WI-38) cells, and human melanoma (SK-MEL-3) cells. However, a TPV recombinant with both 15L and the thymidine kinase (TK) gene 66R ablated (TPVΔ15LΔ66R) replicated less efficiently compared to TPVΔ15L and the parental virus. TPVΔ15L exhibited more robust tumor regression in the melanoma-bearing nude mice compared to other TPV recombinants. Our results indicate that deletion of TPV-15L gene product which facilitates the growth of human melanoma cells can be an effective strategy to enhance the oncolytic potential of TPV for the treatment of melanoma.

J Virol Methods 2017; 242:46-52. [PMID: 28093274 DOI: 10.1016/j.jviromet.2017.01.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Revised: 01/10/2017] [Accepted: 01/10/2017] [Indexed: 12/15/2022]
Abstract
Herpes simplex viruses (HSV) are common human pathogens that can cause painful but benign manifestations and recurrent complaints, but can also cause significant morbidity and mortality on infection of the eye or brain and with disseminated infection of an immunosuppressed patient or a neonate. HSV growth inhibition measurement by plaque or yield reduction is a key task in the development of novel antiviral compounds but the manual methods are very labour intensive. The sensitive and specific PCR technology could be an effective method for quantitation of HSV DNA related to virus replication; however the currently described PCR approaches have a major limitation, namely the requirement of purification of DNA from the infected cells. This limitation makes this approach unfeasible for high-throughput screenings. The monitoring of HSV specific antibody titre is essential in vaccination trials and in the improvement of HSV-based oncolytic virotherapy. Usually, conventional cytopathic effect-based and plaque reduction neutralization tests are applied to measure the neutralization titre, but these methods are also time-consuming. To overcome this, we developed a quantitative PCR (qPCR) method for the detection of HSV-2 DNA directly from the infected cells (direct qPCR) and the method was further adapted to measure the titre of HSV specific neutralizing antibody in human sera. The conditions of direct qPCR assay were optimized to measure the antiviral activity of known and novel antiviral substances. Using HSV-2 seronegative and seropositive patients' sera, the validity of the direct qPCR neutralization test was compared to traditional cytopathic effect-based assay. The direct qPCR method was able to detect the HSV-2 DNA quantitatively between multiplicity of infection 1/64 and 1/4194304, indicating that the dynamic range of the detection was approximately 65,500 fold with high correlation between the biological and technical replicates. As a proof of the adaptability of the method, we applied the direct qPCR for antiviral inhibitory concentration 50 (IC50) measurements of known and novel antiviral compounds. The measured IC50 of acyclovir was ∼0.28μg/ml, similar to the previously published IC50 value. The IC50 of novel antiviral candidates was between 1.6-3.1μg/ml. The direct qPCR-based neutralization titres of HSV positive sera were 1:32-1:64, identical to the neutralization titres determined using a traditional neutralization assay. The negative sera did not inhibit the HSV-2 replication in either of the tests. Our direct qPCR method for the HSV-2 growth determination of antiviral IC50 and neutralization titre is less time-consuming, less subjective and a more accurate alternative to the traditional plaque titration and growth reduction assays.

Abstract
The past decade has witnessed impressive new developments for the treatment of melanoma. The discovery of key oncogenic driver mutations, upon which tumor establishment and progression are dependent, changed the prognosis of patients with stage IV disease. Extensive preclinical and clinical studies have shown high response rates and survival benefits over conventional chemotherapies provided by target-specific inhibitors of BRAF- or NRAS-activating mutations. Recent genomic analyses of melanoma have also given new potentially targetable driver mutations. In addition, the quickened pace of development of immune checkpoint inhibitors for the treatment of melanoma offers the unique opportunity to provide a long-term clinical benefit. In this emerging era, predictive biomarkers for the selection of patients are required to help us develop an optimal therapeutic strategy.

Abstract
Oncolytic viruses are multifunctional anticancer agents with huge clinical potential, and have recently passed the randomized Phase III clinical trial hurdle. Both wild-type and engineered viruses have been selected for targeting of specific cancers, to elicit cytotoxicity, and also to generate antitumor immunity. Single-agent oncolytic virotherapy treatments have resulted in modest effects in the clinic. There is increasing interest in their combination with cytotoxic agents, radiotherapy and immune-checkpoint inhibitors. Similarly to oncolytic viruses, the benefits of chemotherapeutic agents may be that they induce systemic antitumor immunity through the induction of immunogenic cell death of cancer cells. Combining these two treatment modalities has to date resulted in significant potential in vitro and in vivo synergies through various mechanisms without any apparent additional toxicities. Chemotherapy has been and will continue to be integral to the management of advanced cancers. This review therefore focuses on the potential for a number of common cytotoxic agents to be combined with clinically relevant oncolytic viruses. In many cases, this combined approach has already advanced to the clinical trial arena.
