Abstract
Immunotherapy failures can result from the highly suppressive tumour microenvironment that characterizes aggressive forms of cancer such as recurrent glioblastoma (rGBM)1,2. Here we report the results of a first-in-human phase I trial in 41 patients with rGBM who were injected with CAN-3110-an oncolytic herpes virus (oHSV)3. In contrast to other clinical oHSVs, CAN-3110 retains the viral neurovirulence ICP34.5 gene transcribed by a nestin promoter; nestin is overexpressed in GBM and other invasive tumours, but not in the adult brain or healthy differentiated tissue4. These modifications confer CAN-3110 with preferential tumour replication. No dose-limiting toxicities were encountered. Positive HSV1 serology was significantly associated with both improved survival and clearance of CAN-3110 from injected tumours. Survival after treatment, particularly in individuals seropositive for HSV1, was significantly associated with (1) changes in tumour/PBMC T cell counts and clonal diversity, (2) peripheral expansion/contraction of specific T cell clonotypes; and (3) tumour transcriptomic signatures of immune activation. These results provide human validation that intralesional oHSV treatment enhances anticancer immune responses even in immunosuppressive tumour microenvironments, particularly in individuals with cognate serology to the injected virus. This provides a biological rationale for use of this oncolytic modality in cancers that are otherwise unresponsive to immunotherapy (ClinicalTrials.gov: NCT03152318 ).

Abstract
Abstract
BACKGROUND
CAN-3110 (rQNestin34.5v2) is an HSV-1 oncolytic viral immunotherapy with one copy of the inflammatory ICP34.5 gene under transcriptional control of the Nestin glioma-specific promoter. We completed a phase 1 sequential dose-escalation trial of CAN-3110 in recurrent high-grade glioma (rHGG).
METHODS
CAN-3110 was injected intratumorally starting at 1x106 plaque forming units (pfu) and dose- escalated by half log up to 1x1010 pfu in biopsy confirmed rHGG. An expansion cohort of 12 patients was then accrued at 1x109 pfus. Blood and post-injection rHGG were collected.
RESULTS
41 rHGG patients were treated (42 separate interventions): median age 56 years (range 27-74); 21 females, 20 males; median baseline KPS 90 (range 70-100). CAN-3110 administration was well-tolerated with no dose limiting toxicities. Median overall survival (mOS) was 11.9 months. Histologic and molecular analyses showed significantly increased T cell infiltration in post treatment samples with elevated T cell and/or B cell receptor (TCR/BCR) transcripts which correlated with patient survival (HR 0.26 for patients with elevated TCR/BCR rearrangements as compared to patients with low). Volumetric analyses of MRI suggest a trend between reduction in the relative change in tumor growth, TCR/BCRs enrichment and survival in CAN-3110 treated patients.
CLINICAL IMPLICATIONS
Administration of CAN-3110 into rHGG was well tolerated. OS of CAN-3110 treated subjects compare favorably to historical controls. The association of increased TCR/BCR transcripts with survival suggests that CAN-3110 induces T cell responses against rHGG, supporting further clinical development of CAN-3110 viral immunotherapy.

Abstract
BackgroundRecurrent high-grade glioma (HGG) represents a significant clinical unmet need with expected survival between 6 to 9 months. Oncolytic viruses are a new therapeutic approach for solid tumors that deploy oncolytic activity combined with local and systemic immune activation. CAN-3110 (rQNestin34.5v2) is an oncolytic herpes simplex virus (HSV), modified to encode the HSV1 ICP34.5 protein under control of the nestin promoter. Selective expression of nestin in brain tumors confers tumor-restricted replication of CAN-3110. We conducted an open-label dose-escalation phase 1 clinical trial in patients with recurrent HGG to evaluate safety, tolerability, and immunological changes after CAN-3110 treatment.MethodsThirty patients with biopsy-confirmed recurrent HGG were enrolled from September 2017 to February 2020. CAN-3110 was injected intratumorally starting at 1x106 plaque forming units (pfu) and dose-escalated by half log to 1x1010 pfu. Patients also received standard of care. Peripheral blood mononuclear cells (PBMCs), plasma and tumor samples were collected for analysis at different time-points post treatment. We evaluated HSV antigen expression in tumor tissue. RNA sequencing and T cell receptor (TCR) rearrangement analysis was performed in matched tissue and PBMCs. Cytokine profiling was completed in 29 patients at baseline, day 2, and day 28 post treatment.ResultsEighteen patients were recruited at their first recurrence and 12 at the second recurrence. Three patients presented with multifocal disease. Tumor volume ranged from 357.4 to and 54,036.1mm3 (median 7,733.9mm3, SDV 15,610.2). CAN-3110 was well-tolerated with no dose-limiting toxicity. Median overall survival was 11.7 months. We demonstrated persistence of HSV antigen and CD8+ T cell infiltrates at the site of injected tumor. Preliminary analysis revealed expansion of shared TCR clonotypes and upregulation of pro-inflammatory genes in post-treatment tumors and peripheral blood samples. Longitudinal modeling of cytokine profiling demonstrated increased levels of IL-6, VEGF alpha, CCL2 and IL1-RA and a decrease in GCP-2 levels at day 2 post-treatment (p <0.05). Significant correlations were observed between CXCL2 and CXCL6 (r=0.89 and r=0.95, respectively, at day 2 and day 28 post treatment; p<0.05), CCL2 and CXCL6 (r=0.73 and r=0.61 at days 2 and 28 post treatment; p<0.05) and between CCL2 and CXCL2 (r=0.68, p<0.05 at day 2 post treatment) in patients surviving more than 12 months.ConclusionsIntratumoral administration of CAN-3110 appears well-tolerated in recurrent HGG. Histologic, molecular, and cytokine analyses demonstrate persistence of viral antigen as well as local and systemic immune activation after treatment.Ethics ApprovalThe study was approved by the Office for Human Research Studies at Dana-Farber Cancer Institute, Protocol Number 16–557.

Abstract
2009 Background: Recurrent glioma patients have few therapeutic options and an expected survival of only 7 to 10 months. New treatments to improve the prognosis of this patient population are a dire medical need. Oncolytic viruses (OVs) are emerging as important new agents for cancer treatment. The first FDA approved OV was talimogene laherparepvec (Imlygic, T-Vec) for treatment of melanoma. T-Vec, as most other clinical HSV-1 based OVs, is deleted in the ICP34.5 gene, which is responsible for HSV-1 neurovirulence. However, deletion of ICP34.5 also impedes efficient viral replication. CAN-3110 (rQNestin34.5v2) maintains a copy of the HSV1 ICP34.5 gene under transcriptional control of the tumor-specific promoter for nestin to drive robust tumor-selective replication. CAN-3110 replicates in malignant glioma cells far above levels seen with ICP34.5 deleted viruses. This potency also created the hypothetical risk for increased neurovirulence, thus the regulatory advice to conduct a cautious nine-dose-level Phase-1 dose escalation study in patients with recurrent high-grade glioma (HGG). Methods: From September 2017 to February 2020, thirty patients with biopsy-confirmed recurrent high-grade glioma were treated in an open label clinical trial. Patients with multifocal, multicentric, tumors larger than 5 cm, and tumors that had recurred multiple times were eligible. All patients received best standard of care treatments as indicated by their physician. CAN-3110 was injected intratumorally starting at 1x106 plaque forming units (pfu) and dose-escalating (3+3 design) by half log increments up to 1x1010 pfu. Tissue (when possible) and blood samples were obtained before and during treatment for experimental medicine analyses. Results: CAN-3110 was well tolerated with no dose limiting toxicity observed. The initial tissue diagnosis of the recurrent tumor for the 30 subjects was 26 glioblastoma, 3 anaplastic oligodendroglioma, and 1 anaplastic astrocytoma. The median overall survival (mOS) of the entire study group is 13.25 months. Post-treatment tissue is available for 18/30 subjects and revealed persistence of HSV antigen and CD8+ T cell infiltrates. Additional response, immunologic (including T cell receptor repertoire), transcriptomic and single cell RNA sequencing analyses are ongoing. Conclusions: Administration of CAN-3110 into recurrent glioma was well tolerated without evidence of ICP34.5-induced encephalitis/meningitis. Histological and molecular analyses showed evidence of biological activity and that CAN-3110 injection was associated with immune activation and viral antigen persistence. Although definitive clinical efficacy cannot be determined in this small phase 1 study, OS of CAN-3110 treated subjects compares favorably to historical reports and warrants further clinical studies. Clinical trial information: NCT03152318.

Abstract
Chronic pain represents a major medical burden not only in terms of suffering but also in terms of economic costs. Traditional medical approaches have so far proven insufficient in treating chronic pain and new approaches are necessary. Gene therapy with herpes simplex virus (HSV)-based vectors offers the ability to directly target specific regions of the neuraxis involved in pain transmission including the primary afferent nociceptor. This opens up new targets to interact with that are either not available to traditional systemic drugs or cannot be adequately acted upon without substantial adverse off-target effects. Having access to the entire neuron, which HSV-based vector gene therapy enables, expands treatment options beyond merely treating symptoms and allows for altering the basic biology of the nerve. In this paper, we discuss several HSV-based gene therapy vectors that our group and others have used to target specific neuronal functions involved in the processing of nociception in order to develop new therapies for the treatment of chronic pain.

Abstract
Peripheral neuropathic pain is one of the most common and debilitating complications of diabetes. Several genes have been shown to be effective in reducing neuropathic pain in animal models of diabetes after transfer to the dorsal root ganglion using replication-defective herpes simplex virus (HSV)1-based vectors, yet there has never been a comparative analysis of their efficacy. We compared four different HSV1-based vectors engineered to produce one of two opioid receptor agonists (enkephalin or endomorphin), or one of two isoforms of glutamic acid decarboxylase (GAD65 or GAD67), alone and in combination, in the streptozotocin-induced diabetic rat and mouse models. Our results indicate that a single subcutaneous hindpaw inoculation of vectors expressing GAD65 or GAD67 reduced diabetes-induced mechanical allodynia to a degree that was greater than daily injections of gabapentin in rats. Diabetic mice that developed thermal hyperalgesia also responded to GAD65 or endomorphin gene delivery. The results suggest that either GAD65 or GAD67 vectors are the most effective in the treatment of diabetic pain. The vector combinations, GAD67+endomorphin, GAD67+enkephalin or endomorphin+enkephalin also produced a significant antinociceptive effect but the combination did not appear to be superior to single gene treatment. These findings provide further justification for the clinical development of antinociceptive gene therapies for the treatment of diabetic peripheral neuropathies.

Abstract
BACKGROUND The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function in patients with recent-onset type 1 diabetes. METHODS We studied 334 patients, 10 to 20 years of age, with type 1 diabetes, fasting C-peptide levels of more than 0.3 ng per milliliter (0.1 nmol per liter), and detectable serum GAD65 autoantibodies. Within 3 months after diagnosis, patients were randomly assigned to receive one of three study treatments: four doses of GAD-alum, two doses of GAD-alum followed by two doses of placebo, or four doses of placebo. The primary outcome was the change in the stimulated serum C-peptide level (after a mixed-meal tolerance test) between the baseline visit and the 15-month visit. Secondary outcomes included the glycated hemoglobin level, mean daily insulin dose, rate of hypoglycemia, and fasting and maximum stimulated C-peptide levels. RESULTS The stimulated C-peptide level declined to a similar degree in all study groups, and the primary outcome at 15 months did not differ significantly between the combined active-drug groups and the placebo group (P=0.10). The use of GAD-alum as compared with placebo did not affect the insulin dose, glycated hemoglobin level, or hypoglycemia rate. Adverse events were infrequent and mild in the three groups, with no significant differences. CONCLUSIONS Treatment with GAD-alum did not significantly reduce the loss of stimulated C peptide or improve clinical outcomes over a 15-month period.

Abstract
OBJECTIVE Preclinical evidence indicates that gene transfer to the dorsal root ganglion using replication-defective herpes simplex virus (HSV)-based vectors can reduce pain-related behavior in animal models of pain. This clinical trial was carried out to assess the safety and explore the potential efficacy of this approach in humans. METHODS We conducted a multicenter, dose-escalation, phase I clinical trial of NP2, a replication-defective HSV-based vector expressing human preproenkephalin (PENK) in subjects with intractable focal pain caused by cancer. NP2 was injected intradermally into the dermatome(s) corresponding to the radicular distribution of pain. The primary outcome was safety. As secondary measures, efficacy of pain relief was assessed using a numeric rating scale (NRS), the Short Form McGill Pain Questionnaire (SF-MPQ), and concurrent opiate usage. RESULTS Ten subjects with moderate to severe intractable pain despite treatment with >200mg/day of morphine (or equivalent) were enrolled into the study. Treatment was well tolerated with no study agent-related serious adverse events observed at any point in the study. Subjects receiving the low dose of NP2 reported no substantive change in pain. Subjects in the middle- and high-dose cohorts reported pain relief as assessed by NRS and SF-MPQ. INTERPRETATION Treatment of intractable pain with NP2 was well tolerated. There were no placebo controls in this relatively small study, but the dose-responsive analgesic effects suggest that NP2 may be effective in reducing pain and warrants further clinical investigation.

Abstract
The first human trial of gene therapy for chronic pain, a phase 1 study of a nonreplicating herpes simplex virus (HSV)-based vector engineered to express preproenkephalin in patients with intractable pain from cancer, began enrolling subjects in December 2008. In this article, we describe the rationale underlying this potential approach to treatment of pain, the preclinical animal data in support of this approach, the design of the study, and studies with additional HSV-based vectors that may be used to develop treatment for other types of pain.

Abstract
Advances in identification and characterization of gene products responsible for specific diseases of the nervous system have opened opportunities for novel therapies using gene transfer vectors for gene replacement. Herpes simplex virus (HSV)-based vectors are particularly well suited for gene delivery to neurons of the central and peripheral nervous systems. The authors have developed methods to delete HSV-1 IE gene functions and to subsequently introduce foreign genes into the HSV-1 genome using homologous recombination. This unit describes methods for generating cell lines that complement multiple essential gene deletion mutants as well for generating such replication-defective virus recombinants and inserting foreign DNA sequences into replication-defective viral genomes, the last step in preparing a vector. Three support protocols describe methods for preparing virus stocks, titering virus, and preparing viral DNA.

Abstract
Pathological alterations of ion channel activity result from changes in modulatory mechanisms governing receptor biology. Here we describe a conditional herpes simplex virus (HSV) replication-based strategy to discover channel modulators whereby inhibition of agonist-induced channel activation by a vector-expressed modulatory gene product prevents ion flux, osmotic shock and cell death. Inhibition of channel activity, in this case, the rat vanilloid (Trpv1 or the glycine receptor (GlyRalpha1), can allow selection of escape vector plaques containing the 'captured' modulatory gene for subsequent identification and functional analysis. We validated this prediction using mixed infections of a wild-type Trpv1 expression vector vTTHR and a nonfunctional 'poreless' Trpv1 subunit-expressing vector, vHP, wherein vHP was highly selected from a large background of vTTHR viruses in the presence of the Trpv1 agonist, capsaicin. The approach should be useful for probing large libraries of vector-expressed cDNAs for the presence of ion channel modulators.

Abstract
Metal catalyzed oxidation (MCO), which typically involves oxygen free radical generation, is an important pathway that leads to the deterioration of many biological molecules in solution. The occurrence of MCO in immobilized metal affinity chromatography (IMAC) systems and its potential for inactivating biological products has not been well recognized. In this study, we report the inactivation of herpes simplex virus type 1 (HSV-1) gene therapy vector on immobilized cobalt affinity chromatography. We observed that purification of KgBHAT, an HSV-1 mutant bearing cobalt affinity tags (HAT) on the surface, on an IDA-Co2+ column using crude supernatant as starting material resulted in signification loss in virus infectivity (<5% recovery). Electron spin resonance (ESR) revealed that the virus inactivation was caused by hydroxyl free radicals generated from the interactions between cellular impurities and the metal ions on the column. Inclusion of 20 mM ascorbate, a free radical scavenger, in the chromatography mobile phase effectively scavenged the hydroxyl radicals and dramatically augmented the infectivity recovery to 70%. This finding is the first demonstration of oxygen free radical-mediated biological inactivation in an actual IMAC purification and the way on how to effectively prevent it.

Abstract
To investigate the neuroprotective effects of erythropoietin (EPO) in a rodent model of Parkinson disease, we inoculated a nonreplicating herpes simplex virus-based vector expressing EPO (vector DHEPO) into the striatum of mice 1 week prior to, or 2 weeks after, the start of continual administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (4 mg/kg intraperitoneally, 5 of 7 days) for 6 weeks. Inoculation with DHEPO prior to MPTP intoxication preserved behavioral function measured by pellet retrieval and the histological markers of tyrosine hydroxylase-immunoreactive (TH-IR) neuronal cell bodies in the substantia nigra (SN) and TH-IR and dopamine transporter-immunoreactive (DAT-IR) terminals in striatum. Inoculation of DHEPO 2 weeks into a 6-week course of MPTP resulted in improvement of behavioral function and restoration of TH-IR cells in SN and TH- and DAT-IR in the striatum. The effects of vector-produced EPO were similar in magnitude to the effects of vector-mediated expression of glial-derived neurotrophic factor in the same model. These results demonstrate that vector-mediated EPO production may be used to reverse dopaminergic neurodegeneration in the face of continued toxic insult.

Abstract
We examined the utility of herpes simplex virus (HSV) vector-mediated gene transfer of vascular endothelial growth factor (VEGF) in a mouse model of diabetic neuropathy. A replication-incompetent HSV vector with VEGF under the control of the HSV ICP0 promoter (vector T0VEGF) was constructed. T0VEGF expressed and released VEGF from primary dorsal root ganglion (DRG) neurons in vitro, and following subcutaneous inoculation in the foot, expressed VEGF in DRG and nerve in vivo. At 2 weeks after induction of diabetes, subcutaneous inoculation of T0VEGF prevented the reduction in sensory nerve amplitude characteristic of diabetic neuropathy measured 4 weeks later, preserved autonomic function measured by pilocarpine-induced sweating, and prevented the loss of nerve fibers in the skin and reduction of neuropeptide calcitonin gene-related peptide and substance P in DRG neurons of the diabetic mice. HSV-mediated transfer of VEGF to DRG may prove useful in treatment of diabetic neuropathy.

Abstract
Malignant glioma is a fatal human cancer in which surgery, chemo- and radiation therapies are ineffective. Therapeutic gene transfer used in combination with current treatment methods may augment their effectiveness with improved clinical outcome. We have shown that NUREL-C2, a replication-defective multigene HSV-based vector, is effective in treating animal models of glioma. Here, we report safety and biodistribution studies of NUREL-C2 using rhesus macaques as a model host. Increasing total doses (1 x 10(7) to 1 x 10(9) plaque forming units (PFU)) of NUREL-C2 were delivered into the cortex with concomitant delivery of ganciclovir (GCV). The animals were evaluated for changes in behavior, alterations in blood cell counts and chemistry. The results showed that animal behavior was generally unchanged, although the chronic intermediate dose animal became slightly ataxic on day 12 postinjection, a condition resolved by treatment with aspirin. The blood chemistries were unremarkable for all doses. At 4 days following vector injections, magnetic resonance imaging showed inflammatory changes at sites of vector injections concomitant with HSV-TK and TNFalpha expression. The inflammatory response was reduced at 14 days, resolving by 1 month postinjection, a time point when transgene expression also became undetectable. Immunohistochemical staining following animal killing showed the presence of a diffuse low-grade gliosis with infiltrating macrophages localized to the injection site, which also resolved by 1 month postinoculation. Viral antigens were not detected and injected animals did not develop HSV-neutralizing antibodies. Biodistribution studies revealed that vector genomes remained at the site of injection and were not detected in other tissues including contralateral brain. We concluded that intracranial delivery of 1 x 10(9) PFU NUREL-C2, the highest anticipated patient dose, was well tolerated and should be suitable for safety testing in humans.

Abstract
To develop a cellular vehicle able to reach systemically disseminated areas of angiogenesis, we sought to exploit the natural tropism of circulating endothelial progenitor cells (EPCs). Primate CD34+ EPCs were genetically modified with high efficiency and minimal toxicity using a non-replicative herpes virus vector. These EPCs localized in a skin autograft model of angiogenesis in rhesus monkeys, and sustained the expression of a reporter gene for several weeks while circulating in the blood. In animals infused with autologous CD34+ EPCs transduced with a thymidine kinase-encoding herpes virus, skin autografts and subcutaneous Matrigel pellets impregnated with vascular growth factors underwent necrosis or accelerated regression after administration of ganciclovir. Importantly, the whole intervention was perfectly well tolerated. The accessibility, easy manipulation, lack of immunogenicity of the autologous CD34+ cell vehicles, and tropism for areas of angiogenesis render autologous CD34+ circulating endothelial progenitors as ideal candidates for exploration of their use as cellular vehicles when systemic gene delivery to those areas is required.

Abstract
To evaluate the use of HSV-based vectors for arthritis gene therapy we have constructed a first-generation, ICP4 deficient, replication defective herpes simplex virus (HSV) vector (S/0-) and a second-generation HSV vector derivative (T/0-) deficient for the immediate-early genes ICP4, 22 and 27, each carrying a soluble TNF receptor or IL-1 receptor antagonist transgene cassette. A rabbit synovial-fibroblast line in culture, infected by either vector enabled high-level expression of the transgene product. However, following a single intra-articular injection of the vectors into rabbit knee joints, only the second-generation, HSV T/0- vector expressed detectable levels of soluble TNFR in synovial fluid. Synovial lavage fluid from inoculated joints con- tained up to 12 ng/ml of soluble receptor that persisted at detectable, but reduced levels for at least 7 days. When tested in an experimental model of arthritis generated by intra-articular overexpression of interleukin-1beta using retrovirus transduced synovial cells, the HSV T/0- vector expressing the interleukin-1 receptor antagonist was found to inhibit leukocytosis and synovitis significantly. The improved levels and duration of intra-articular transgene expression achieved via HSV-mediated gene delivery suggest that an HSV vector system could be used for therapeutic applications in patients with rheumatoid arthritis (RA) and other joint-related inflammatory diseases.

Abstract
We report here the construction and the use of two replication-defective herpes simplex virus vectors, SH FGF-2 and TH FGF-2, which efficiently transfer and express the cDNA for fibroblast-growth-factor-2 (FGF-2) in vitro and in vivo. One mutant was deleted in the immediate-early gene encoding ICP4; the other was deleted in ICP4, ICP22 and ICP27. FGF-2--or the control gene lacZ--were inserted in tk, under control of the human cytomegalovirus immediate-early promoter. Infection of Vero cells with SH FGF-2 induced a dramatic increase in FGF-2 protein levels in the first 2 days after infection, with a rapid return to baseline levels within day 4. In contrast, infection of Vero cells with TH FGF-2 displayed FGF-2 levels progressively increasing up to days 4-5, and slowly returning to baseline. Protein extracts of cells infected with TH FGF-2 induced neuronal differentiation of PC12 cells, indicating that the newly synthesized FGF-2 was biologically active. Robust transient transgene expression was also observed in the rat hippocampus after stereotaxical inoculation of TH FGF-2, but not of TH lacZ or of SH vectors. Enhanced gene expression both in vitro and in vivo by the triple immediate-early gene deletion mutant might be attributed to reduced vector cytotoxicity. The present data suggest that TH FGF-2 is suitable for studies of FGF-2 involvement in neurological disorders.

Abstract
Past studies have documented the promise of herpes simplex virus type 1 (HSV-1) thymidine kinase (TK) suicide gene therapy as a potential antitumor treatment. HSV-TK converts the pro-drug ganciclovir (GCV) into a toxic nucleotide analogue, the incorporation of which into cellular DNA blocks cell proliferation. In this report, we have examined the hypothesis that the effectiveness of HSV-TK suicide gene therapy can be enhanced by coexpression of the antitumor cytokine human tumor necrosis factor-alpha (TNF-alpha) from the same replication-defective HSV-1 vector. In vitro testing demonstrated that TNF-alpha expression from this vector potentiated the killing of both TNF-alpha-sensitive L929 tumor cells and TNF-alpha-resistant U-87 MG cells in the presence of GCV. Furthermore, treatment of established intradermal L929 tumors in vivo with the TNF-alpha/TK vector and GCV resulted in prolonged animal survival compared with treatment with parental HSV-TK vector in the presence or absence of GCV. Treatment of intracerebral U-87 MG tumors showed a clear benefit of TK therapy, but a significant further increase in survival using the TNF-alpha vector could not be demonstrated. We found that potentiation of cell killing in vitro required intracellular TNF-alpha because purified protein added to the culture medium of cells infected with HSV-TK vector failed to have the same effect. Accordingly, potentiation in vivo should depend on efficient infection, but immunohistochemical analysis indicated that virus administration by U-87 MG intratumoral injection was inadequate, resulting in an estimated <1% infection of all tumor cells. Moreover, the majority of infected tumor cells were localized at the tumor margin. Together, these results suggest that TNF-enhanced tk gene therapy should provide a useful treatment for TNF-alpha-sensitive tumors and perhaps also for TNT-alpha-resistant tumors if vector delivery can be improved to increase the percentage of transduced tumor cells.

Abstract
In this report, a replication-defective herpes simplex virus type 1 (HSV-1) vector has been employed to deliver the Escherichia coli LacZ and HSV thymidine kinase (HSVtk) genes to six human ovarian carcinoma cell lines and the efficacy of gene transfer compared to that of adenoviral vectors in vitro. The transduction efficiency of the LacZ-containing virus TOZ.1 was evaluated qualitatively and quantitatively following infection of the different ovarian cancer cell lines. The therapeutic ability of the HSV-T3 vector, which contains the HSVtk gene, was additionally investigated in comparison to the AdCMVHSVTK. Our results show that HSV-1-mediated gene transfer is quantitatively superior to adenoviral vector in five of the six ovarian cancer cell lines at a 100-fold lower dose in vitro. Our preliminary studies suggest that HSV-1 may be a promising alternative vector for ovarian cancer gene therapy.

Abstract
Different viral vectors have been analyzed as gene delivery vehicles to skeletal muscle for potentially therapeutic purposes. In this review, we evaluate the application of retroviral, adenoviral, and herpes simplex viral vectors to deliver genes to skeletal muscle and focus on the dramatic loss of viral transduction detected throughout muscle maturation. Recent results suggested that there are several factors involved in the reduced viral transducibility of mature skeletal muscle: muscle cells become post-mitotic in an early stage, the extracellular matrix develops into a physical barrier, and a loss of myoblast mediation occurs since myoblasts progressively become quiescent. Approaches to improve viral gene delivery to mature skeletal muscle may include the use of particular enzymes to increase the permeability of the extracellular matrix, the pre-treatment of the muscle with a myonecrotic agent to induce myoblast mediation, or the application of the myoblast-mediated ex vivo gene transfer.

Abstract
Arthritis is presently incurable and poorly treatable, but there are good grounds for expecting gene therapy to improve matters considerably. Although local ex vivo delivery of anti-arthritic genes to the synovial lining of joints has shown considerable promise, intraarticular gene delivery may be desirable. Herpes simplex virus (HSV) may be a viable vector for in vivo transfer of anti-arthritic genes to joints. HSV has the advantages of high infectivity, large carrying capacity and high titer. The large packaging capacity would permit the inclusion of multiple anti-arthritic genes and necessary regulatory elements. Recombinant vectors produced by this laboratory infect synovial cells efficiently, permitting prolonged expression of transgenes in vitro and in vivo without evidence of cytotoxicity. Further improvements to this vector system include taking advantage of an endogenous HSV 'stealthing' gene, ICP47, which interferes with formation of antigen-class I complexes. Inclusion of inducible promoters to appropriately regulate expression of anti-arthritic genes should further improve this system.

Abstract
The main goal of gene therapy for Duchenne muscular dystrophy (DMD) is to restore dystrophin into as many muscle cells as necessary to be therapeutic. Herpes simplex virus type 1 (HSV-1) represents a promising new viral vector capable of efficient transduction of myofibers in vivo. The viral genome is large and can accommodate multiple or large non-viral genes including the full-length dystrophin. Here we report on the use of a replication defective HSV-1 mutant vector (DZ) deleted for the essential immediate early (IE) gene ICP4 for studies of reporter gene transfer and expression following direct inoculation of mouse skeletal muscle. Our initial experiments showed that HSV-1 can efficiently infect and express a foreign reporter gene in myoblasts and myotubes in vitro. Furthermore, the intramuscular inoculation of HSV-1 resulted in transduction of a significant number of muscle fibers in newborn mice and some muscle fibers in adult animals. We have attempted to exploit these features to develop new HSV mutant vectors for dystrophin gene delivery to DMD muscle, however two impediments to using this virus for muscle gene delivery have to be overcome: namely viral cytotoxicity and the differential transducibility with HSV-1 throughout the development of muscle fibers. To solve the first problem, virus mutants deleted for the immediate early (IE) genes (ICP4, ICP22, ICP27 and UL41) were constructed and the multiple deleted virus was greatly reduced in cytotoxicity relative to our first generation HSV vector strains. Current work is aimed at incorporating full-length dystrophin under muscle specific promoter (muscle creatine kinase MCK) into these new viral vectors. To address the second problem we have analysed by immunohistochemistry the spreading of the HSV-1 in newborn versus adult muscles to determine whether mature basal lamina which surrounds the adult muscle fibers blocks the HSV-1 entry into the mature muscle fibers.

Abstract
Herpes simplex virus (HSV) represents a candidate gene transfer vector for the treatment of nervous system disease. It has many natural biological features which make it attractive for gene delivery to a variety of tissues. The virus naturally establishes a latency in sensory neurons of the peripheral nervous system, wherein the virus in maintained as an extrachromosomal DNA element in the absence of viral lytic gene expression without altering the metabolism of the host neuron. The virus possesses a neuronal latency-specific promoter system which remains active long-term, while other viral and cellular promoters are repressed. Replication defective virus recombinants have been engineered to delete multiple essential immediate early gene functions rendering these new mutants significantly less cytotoxic to neurons and other cells in culture. Further developments in regulating transgene expression and reducing virus toxicity will continue to aid the design and use of these vectors for therapeutic applications for the nervous system.

Abstract
Numerous diseases of the nervous system result from single gene or multifactorial gene defects such as cancer, immune pathological disorders, metabolic diseases, and common neurodegenerative syndromes (Parkinson's and Alzheimer's diseases). A greater understanding of the molecular, biochemical, and genetic factors involved in the progression of a specific disease state has led to the development of genetic therapies using direct gene transfer to ameliorate the disease condition or correct a genetic defect in situ. Standard gene therapeutic approaches employing retroviruses have not proven feasible for treating disorders of the central nervous system (CNS) since these vectors require dividing cells for integration and expression of the transgene, whereas CNS neurons are postmitotic, terminally differentiated cells. Thus, methods for delivery and expression of therapeutic gene products to treat CNS disease will require new delivery strategies and vehicles including the development of novel vectors for direct gene transfer. These vectors should: efficiently deliver the therapeutic gene(s) to a sufficient number of nondividing neurons; persist long-term in a nonintegrated state within the nerve cell nucleus without disturbing host cell functions; and be able to regulate therapeutic gene expression for diseases that may either require high-level transient transgene expression or continuous low level synthesis of the therapeutic product.
