C Franklin, E Livingstone, A Roesch, B Schilling, D Schadendorf
Malignant melanoma contributes the majority of skin cancer related deaths and shows an increasing incidence in the past years. Despite all efforts of early diagnosis, metastatic melanoma still has a poor prognosis and remains a challenge for treating physicians. In recent years, improved knowledge of the pathophysiology and a better understanding of the role of the immune system in tumour control have led to the development and approval of several immunotherapies. Monoclonal antibodies against different immune checkpoints have been revolutionizing the treatment of metastatic and unresectable melanoma...

BACKGROUND: Little has been reported on the costs of managing the adverse events (AEs) associated with current therapies for patients with regional or distant metastatic melanoma. OBJECTIVES: To identify treatment-related AEs in patients with metastatic melanoma and to estimate the associated costs of treating these AEs in the United States. METHODS: A cost-estimation study for AEs associated with treatment of metastatic melanoma was conducted from 2012 to 2013 by identifying grades 3 and 4 AEs through the use of a comprehensive search of drug labels and English-language, published phase 2/3 studies in PubMed, conference abstracts, and the National Comprehensive Cancer Network guidelines...

The innate immune regulator STING stimulates cytokine production in response to the presence of cytosolic DNA, which can arise following DNA damage. Extrinsic STING signaling is also needed for antigen-presenting cells (APC) to stimulate antitumor T cell immunity. Here we show that STING signaling is recurrently suppressed in melanoma cells, where this event may enable immune escape after DNA damage. Mechanistically STING signaling was suppressed most frequently by epigenetic silencing of either STING or the cyclic GMP-AMP synthase (cGAS), which generates STING-activating cyclic dinucleotides (CDNs) after binding cytosolic DNA species...

With the recent regulatory approval of Talimogene laherparepvec (T-VEC) for the treatment of advanced of melanoma in the United States, Europe and Australia, oncolytic virus immunotherapy has earned its place in the clinic. However, the adoption of T-VEC by the U.S. oncology community has been slow, and so far has been largely limited to specialized cancer centers. Limiting factors include the intratumoral route of administration, which is unfamiliar to medical oncologists, biosafety concerns related to the use of a live virus in the clinic, and the explosion of other therapeutic strategies now available for the treatment of advanced melanoma...

The landscape of advanced and metastatic melanoma therapy has shifted dramatically in recent years. Since 2011, eight drugs (ipilimumab, vemurafenib, dabrafenib, trametinib, cometinib, pembrolizumab, nivolumab, and talimogene laherparepvec) have received FDA approval for the treatment of advanced or metastatic melanoma, including combination regimens of both small molecule kinase and immune checkpoint inhibitors. These therapies have revolutionized the management of unresectable regional nodal and distant melanoma, providing hope of extended survival to patients...

For decades, effective cancer gene therapy has been a tantalising prospect; for a therapeutic modality potentially able to elicit highly effective and selective responses, definitive efficacy outcomes have often seemed out of reach. However, steady progress in vector development and accumulated experience from previous clinical studies has finally led the field to its first licensed therapy. Following a pivotal phase III trial, Imlygic (talimogene laherparepvec/T-Vec) received US approval as a treatment for cutaneous and subcutaneous melanoma in October 2015, followed several weeks later by its European authorisation...

INTRODUCTION: Immunotherapy has revolutionized the treatment of metastatic melanoma and dramatically improved patient outcomes. Ipilimumab, an inhibitor of cytotoxic T-lymphocyte antigen-4 (CTLA-4), was the first immunotherapeutic agent to demonstrate improved survival in advanced melanoma. More recently, other immune checkpoint inhibitors, including the programmed death-1 (PD-1) inhibitors pembrolizumab and nivolumab, have demonstrated efficacy in locally advanced unresectable and metastatic melanoma...

Talimogene laherparepvec (Imlygic™) is a first-in-class oncolytic viral immunotherapy derived from herpes simplex virus type 1, which has been genetically modified to increase tumour selectivity and stimulate antitumour immune response. This article reviews the pharmacological properties of intralesional talimogene laherparepvec and its clinical efficacy and tolerability in patients with unresectable metastatic melanoma. In the phase III OPTiM trial, talimogene laherparepvec was more effective than subcutaneous human granulocyte-macrophage colony-stimulating factor (GM-CSF), both in patients with stage IIIB-IV melanoma [intention-to-treat (ITT) population] and in those with stage IIIB-IVM1a disease (in an exploratory subgroup analysis)...

Oncolytic virotherapy exploits the properties of human viruses to naturally cytolysis of cancer cells. The human pathogen herpes simplex virus (HSV) has proven particularly amenable for use in oncolytic virotherapy. The relative safety of HSV coupled with extensive knowledge on how HSV interacts with the host has provided a platform for manipulating HSV to enhance the targeting and killing of human cancer cells. This has culminated in the approval of talimogene laherparepvec for the treatment of melanoma. This review focuses on the development of HSV as an oncolytic virus and where the field is likely to head in the future...

Oncolytic viruses that selectively lyse tumor cells with minimal damage to normal cells are a new area of therapeutic development in oncology. An attenuated herpesvirus encoding the granulocyte-macrophage colony stimulating factor (GM-CSF), known as talimogene laherparepvec (T-VEC), has been identified as an attractive oncolytic virus for cancer therapy based on preclinical tumor studies and results from early-phase clinical trials and a large randomized Phase III study in melanoma. In this review, we discuss the basic biology of T-VEC, describe the role of GM-CSF as an immune adjuvant, summarize the preclinical data, and report the outcomes of published clinical trials using T-VEC...

Oncolytic viruses are emerging as a potential new way of treating cancers. They are selectively replication-competent viruses that propagate only in actively dividing tumor cells but not in normal cells and, as a result, destroy the tumor cells by consequence of lytic infection. At least six different oncolytic herpes simplex viruses (oHSVs) have undergone clinical trials worldwide to date, and they have demonstrated an excellent safety profile and intimations of efficacy. The first pivotal Phase III trial with an oHSV, talimogene laherparepvec (T-Vec [OncoVex(GM-CSF)]), is almost complete, with extremely positive early results reported...

Oncolytic virus therapy is perhaps the next major breakthrough in cancer treatment following the success in immunotherapy using immune checkpoint inhibitors. Oncolytic viruses are defined as genetically engineered or naturally occurring viruses that selectively replicate in and kill cancer cells without harming the normal tissues. T-Vec (talimogene laherparepvec), a second-generation oncolytic herpes simplex virus type 1 (HSV-1) armed with GM-CSF, was recently approved as the first oncolytic virus drug in the USA and Europe...

Importance: Oncolytic viruses (OVs) are emerging as important agents in cancer treatment. Oncolytic viruses offer the attractive therapeutic combination of tumor-specific cell lysis together with immune stimulation, therefore acting as potential in situ tumor vaccines. Moreover, OVs can be engineered for optimization of tumor selectivity and enhanced immune stimulation and can be readily combined with other agents. The effectiveness of OVs has been demonstrated in many preclinical studies and recently in humans, with US Food and Drug Administration approval of the oncolytic herpesvirus talimogene laherparepvec in advanced melanoma, a major breakthrough for the field...

BACKGROUND: Cutaneous head and neck melanoma has poor outcomes and limited treatment options. In OPTiM, a phase 3 study in patients with unresectable stage IIIB/IIIC/IV melanoma, intralesional administration of the oncolytic virus talimogene laherparepvec improved durable response rate (DRR; continuous response ≥6 months) compared with subcutaneous granulocyte-macrophage colony-stimulating factor (GM-CSF). METHODS: Retrospective review of OPTiM identified patients with cutaneous head and neck melanoma given talimogene laherparepvec (n = 61) or GM-CSF (n = 26)...

Several immunomodulatory checkpoint inhibitors have been approved for the treatment of patients with advanced melanoma, including ipilimumab, nivolumab and pembrolizumab. Talimogene laherparepvec is the first oncolytic virus to gain regulatory approval in the USA; it is also approved in Europe. Talimogene laherparepvec expresses granulocyte-macrophage colony-stimulating factor (GM-CSF), and with other GM-CSF-expressing oncolytic viruses in development, understanding the clinical relevance of this cytokine in treating advanced melanoma is important...

PURPOSE: Talimogene laherparepvec (T-VEC) is an oncolytic immunotherapy designed to induce tumor regression of injected lesions through direct lytic effects, and of uninjected lesions through induction of systemic antitumor immunity. In this study, we describe the patterns and time course of response to T-VEC from the phase III OPTiM trial of 436 patients with unresected stages IIIB-IV melanoma. METHODS: Lesion-level response analyses were performed based on the type of lesion (injected or uninjected cutaneous, subcutaneous, or nodal lesions; or visceral lesions [uninjected]), and the best percentage change from baseline of the sum of products of the longest diameters was calculated...

PURPOSE: Combining immunotherapeutic agents with different mechanisms of action may enhance efficacy. We describe the safety and efficacy of talimogene laherparepvec (T-VEC; an oncolytic virus) in combination with ipilimumab (a cytotoxic T-lymphocyte-associated antigen 4 checkpoint inhibitor) in patients with advanced melanoma. METHODS: In this open-label, multicenter, phase Ib trial of T-VEC in combination with ipilimumab, T-VEC was administered intratumorally in week 1 (10(6) plaque-forming units/mL), then in week 4 and every 2 weeks thereafter (10(8) plaque-forming units/mL)...

Over the past 5 years, a host of new agents have radically changed the therapeutic landscape in advanced melanoma; gone are the days when the only active agents were interferon and dacarbazine. Nearly 25 years ago, few patients with stage IV melanoma reached 2-year survival; today, these survival curves have risen substantially. At the NCCN 21st Annual Conference, John A. Thompson, MD, discussed updates with longer duration of patient follow-up for immune checkpoint therapies. He also reviewed some of the newer approvals in advanced melanoma, including the combination of ipilimumab and nivolumab, high-dose ipilimumab, the oncolytic virus therapy talimogene laherparepvec, and the molecularly targeted combination of the BRAF and MEK inhibitors vemurafenib and cobimetinib...
