Abstract
Gene therapy involves the introduction of genetic material into cells as a therapeutic molecule to cure a disease. Through the transfer of specific nucleic acid to the target tissue, gene expression can be downregulated, augmented, or corrected thanks to the nucleic acid sequence as a support of gene expression. This is achieved through molecular interactions according to the sequence arrangement or the secondary structure of the molecules or through their catalytic properties. Over the past two decades, the rapid advances of knowledge and technologies in gene therapy have led to the development of different strategies and to the extension of its use to numerous indications, including certain cancers. Major success has been achieved in clinical trials and the field of gene therapy is booming. Several gene therapy products are now on the market in Europe, the United States, and China. In this review, we cover the basic principles of gene therapy and the characteristics of the main vectors used to transfer genetic material into the cell. As an example of applications, we address the various strategies applied to a rare pediatric muscle disease: Duchenne muscular dystrophy. © 2023 Published by Elsevier Masson SAS on behalf of French Society of Pediatrics.

Abstract
Alipogene tiparvovec (Glybera) is a gene therapy product approved in Europe under the "exceptional circumstances" pathway as a treatment for lipoprotein lipase deficiency (LPLD), a rare genetic disease resulting in chylomicronemia and a concomitantly increased risk of acute and recurrent pancreatitis, with potentially lethal outcome. This retrospective study analyzed the frequency and severity of pancreatitis in 19 patients with LPLD up to 6 years after a single treatment with alipogene tiparvovec. An independent adjudication board of three pancreas experts, blinded to patient identification and to pre- or post-gene therapy period, performed a retrospective review of data extracted from the patients' medical records and categorized LPLD-related acute abdominal pain events requiring hospital visits and/or hospitalizations based on the adapted 2012 Atlanta diagnostic criteria for pancreatitis. Both entire disease time period data and data from an equal time period before and after gene therapy were analyzed. Events with available medical record information meeting the Atlanta diagnostic criteria were categorized as definite pancreatitis; events treated as pancreatitis but with variable levels of laboratory and imaging data were categorized as probable pancreatitis or acute abdominal pain events. A reduction of approximately 50% was observed in all three categories of the adjudicated post-gene therapy events. Notably, no severe pancreatitis and only one intensive care unit admission was observed in the post-alipogene tiparvovec period. However, important inter- and intraindividual variations in the pre- and post-gene therapy incidence of events were observed. There was no relationship between the posttreatment incidence of events and the number of LPL gene copies injected, the administration of immunosuppressive regimen or the percent triglyceride decrease achieved at 12 weeks (primary end point in the prospective clinical studies). Although a causal relationship cannot be established and despite the limited number of individuals evaluated, results from this long-term analysis suggest that alipogene tiparvovec was associated with a lower frequency and severity of pancreatitis events, and a consequent overall reduction in health care resource use up to 6 years posttreatment.

Abstract
Summary Recombinant human binding immunoglobulin protein (BiP) has previously demonstrated anti-inflammatory properties in multiple models of inflammatory arthritis. We investigated whether these immunoregulatory properties could be exploited using gene therapy techniques. A single intraperitoneal injection of lentiviral vector containing the murine BiP (Lenti-mBiP) or green fluorescent protein (Lenti-GFP) transgene was administered in low- or high-dose studies during early arthritis. Disease activity was assessed by visual scoring, histology, serum cytokine and antibody production measured by cell enzyme-linked immunosorbent assay (ELISA) and ELISA, respectively. Lentiviral vector treatment caused significant induction of interferon (IFN)-γ responses regardless of the transgene; however, further specific effects were directly attributable to the BiP transgene. In both studies Lenti-mBiP suppressed clinical arthritis significantly. Histological examination showed that low-dose Lenti-mBiP suppressed inflammatory cell infiltration, cartilage destruction and significantly reduced pathogenic anti-type II collagen (CII) antibodies. Lenti-mBiP treatment caused significant up-regulation of soluble cytotoxic T lymphocyte antigen-4 (sCTLA-4) serum levels and down-regulation of interleukin (IL)-17A production in response to CII cell restimulation. In-vitro studies confirmed that Lenti-mBiP spleen cells could significantly suppress the release of IL-17A from CII primed responder cells following CII restimulation in vitro, and this suppression was associated with increased IL-10 production. Neutralization of CTLA-4 in further co-culture experiments demonstrated inverse regulation of IL-17A production. In conclusion, these data demonstrate proof of principle for the therapeutic potential of systemic lentiviral vector delivery of the BiP transgene leading to immunoregulation of arthritis by induction of soluble CTLA-4 and suppression of IL-17A production.

Abstract
In spite of popularity of TNF-α antagonist in the treatment of rheumatoid arthritis (RA), their modes of action are not fully understood. In the present study, we further explore the effects of gene transfer route of a TNF-α antagonist on arthritis. Recombinant adeno-associated virus 2 (rAAV2) encoding rat TNF receptor-immunoglobulin Fc (ratTNFR:Fc) fusion gene was injected intraarticularly in rats with collagen-induced arthritis (CIA). As revealed by examination of the clinical, radiographical, and histological aspects, local gene transfer of rAAV2/ratTNFR:Fc ameliorated the arthritis symptoms and inhibited the development of CIA. Compared with the vector control group, expressions of TNF-α, IL-1, and IFN-γ were down-regulated, and IL-10 release was up-regulated in the rAAV2/ratTNFR:Fc-treated group. Furthermore, administration of rAAV2/ratTNFR:Fc ameliorated the enlargement of spleen and significantly reduced spleen cell proliferation. Low level of nitric oxide (NO) in spleen was observed in CIA rats following the delivery of rAAV2/ratTNFR:Fc when compared to the vector control group. This study provides the evidence that intraarticular delivery of rAAV2/ratTNFR:Fc suppress the progression of arthritis by restoring the balance between pro-inflammatory and anti-inflammatory cytokines and inhibiting spleen cell proliferation. Our findings also implicate that the down-regulation of NO release on arthritis is involved in the anti-inflammatory mechanisms of TNF-α antagonist.

Abstract
BACKGROUND Adeno-associated virus type 1/sarcoplasmic reticulum Ca(2+)-ATPase was assessed in a randomized, double-blind, placebo-controlled, phase 2 study in patients with advanced heart failure. METHODS AND RESULTS Thirty-nine patients received intracoronary adeno-associated virus type 1/sarcoplasmic reticulum Ca(2+)-ATPase or placebo. Seven efficacy parameters were assessed in 4 domains: symptoms (New York Heart Association class, Minnesota Living With Heart Failure Questionnaire), functional status (6-minute walk test, peak maximum oxygen consumption), biomarker (N-terminal prohormone brain natriuretic peptide), and left ventricular function/remodeling (left ventricular ejection fraction, left ventricular end-systolic volume), plus clinical outcomes. The primary end point success criteria were prospectively defined as achieving efficacy at 6 months in the group-level (concordant improvement in 7 efficacy parameters and no clinically significant worsening in any parameter), individual-level (total score for predefined clinically meaningful changes in 7 efficacy parameters), or outcome end points (cardiovascular hospitalizations and time to terminal events). Efficacy in 1 analysis had to be associated with at least a positive trend in the other 2 analyses. This combination of requirements resulted in a probability of success by chance alone of 2.7%. The high-dose group versus placebo met the prespecified criteria for success at the group-level, individual-level, and outcome analyses (cardiovascular hospitalizations) at 6 months (confirmed at 12 months) and demonstrated improvement or stabilization in New York Heart Association class, Minnesota Living With Heart Failure Questionnaire, 6-minute walk test, peak maximum oxygen consumption, N-terminal prohormone brain natriuretic peptide levels, and left ventricular end-systolic volume. Significant increases in time to clinical events and decreased frequency of cardiovascular events were observed at 12 months (hazard ratio=0.12; P=0.003), and mean duration of cardiovascular hospitalizations over 12 months was substantially decreased (0.4 versus 4.5 days; P=0.05) on high-dose treatment versus placebo. There were no untoward safety findings. CONCLUSIONS The Calcium Upregulation by Percutaneous Administration of Gene Therapy in Cardiac Disease (CUPID) study demonstrated safety and suggested benefit of adeno-associated virus type 1/sarcoplasmic reticulum Ca(2+)-ATPase in advanced heart failure, supporting larger confirmatory trials.

Abstract
Gel-filtration chromatographic separation of the lysate of Sf21 insect cells infected with recombinant baculovirus BVi67 containing the gene for TNF-binding protein (CrmB) of variola virus (VARV) revealed that hTNF-cytotoxicity neutralization activity is associated with a fraction corresponding mainly to high molecular weight proteins (above 500 kDa) and less with fractions corresponding to proteins of 270 or 90 kDa. The recombinant VARV-CrmB protein has been purified by affinity chromatography. Difference in the experimentally determined and estimated (according to amino acid composition) VARV-CrmB molecular weight is due to glycosylation of the recombinant protein expressed in the insect cells. VARV-CrmB neutralizes in vitro the cytotoxic effect of hTNF and hLTalpha, and its TNF-neutralizing activity is two to three orders of magnitude higher compared to the analogous effects of type I and II soluble TNF receptors, comparable with the activity of mAb MAK195, and somewhat lower than the effect of the commercial drug Remicade.

Abstract
BACKGROUND SERCA2a deficiency is commonly seen in advanced heart failure (HF). This study is designed to investigate safety and biological effects of enzyme replacement using gene transfer in patients with advanced HF. METHODS AND RESULTS A total of 9 patients with advanced HF (New York Heart Association [NYHA] Class III/IV, ejection fraction [EF] < or = 30%, maximal oxygen uptake [VO2 max] <16 mL.kg.min, with maximal pharmacological and device therapy) received a single intracoronary infusion of AAV1/SERCA2a in the open-label portion of this ongoing study. Doses administered ranged from 1.4 x 10(11) to 3 x 10(12) DNase resistant particles per patient. We present 6- to 12-month follow-up data for these patients. AAV1/SERCA2a demonstrated an acceptable safety profile in this advanced HF population. Of the 9 patients treated, several demonstrated improvements from baseline to month 6 across a number of parameters important in HF, including symptomatic (NYHA and Minnesota Living with Heart Failure Questionnaire, 5 patients), functional (6-minute walk test and VO2 max, 4 patients), biomarker (NT-ProBNP, 2 patients), and LV function/remodeling (EF and end-systolic volume, 5 patients). Of note, 2 patients who failed to improve had preexisting anti-AAV1 neutralizing antibodies. CONCLUSIONS Quantitative evidence of biological activity across a number of parameters important for assessing HF status could be detected in several patients without preexisting neutralizing antibodies in this open-label study, although the number of patients in each cohort is too small to conduct statistical analyses. These findings support the initiation of the Phase 2 double-blind, placebo-controlled portion of this study.

Abstract
Periodontal disease is a chronic inflammatory condition induced by tooth-associated microbial biofilms that induce a host immune response. Therapeutic control of progressive tissue destruction in high-risk patients is a significant challenge in therapy. Soluble protein delivery of antagonists to tumor necrosis factor alpha (TNF-α) inhibits alveolar bone resorption due to periodontitis. However, protein therapy raises several concerns, such as recurrence of disease activity after treatment cessation and repeated dosing regimens. In this study, we used pseudotyped adeno-associated virus vector based on serotype 1 (AAV2/1) to deliver the TNF receptor-immunoglobulin Fc (TNFR:Fc) fusion gene to rats subjected to experimental Porphyromonas gingivalis (Pg)-lipopolysaccharide (LPS)-mediated bone loss. Animals received Pg-LPS delivered to the gingivae thrice weekly for 8 weeks, vehicle alone, Pg-LPS and intramuscular delivery of pseudotyped AAV2/1-TNFR:Fc vector (1×1011 DNase I-resistant particles) or AAV2/1-TNFR:Fc vector delivered to naïve animals. AAV2/1-TNFR:Fc therapy led to sustained therapeutic levels of serum TNFR protein and protected against Pg-LPS-mediated loss of bone volume and density. Furthermore, AAV2/1-TNFR:Fc administration reduced local levels of multiple pro-inflammatory cytokines and osteoclast-like cells at the periodontal lesions. These findings suggest that delivery of AAV2/1-TNFR:Fc may be a viable approach to modulate periodontal disease progression.

Abstract
Advances in molecular and cellular biology have identified a wide variety of proteins including targeted cytokine inhibitors, immunomodulatory proteins, cytotoxic mediators, angiogenesis inhibitors, and intracellular signalling molecules that could be of great benefit in the treatment of chronic joint diseases, such as osteo- and rheumatoid arthritis. Unfortunately, protein-based drugs are difficult to administer effectively. They have a high rate of turnover, requiring frequent readministration, and exposure in non-diseased tissue can lead to serious side effects. Gene transfer technologies offer methods to enhance the efficacy of protein-based therapies, enabling the body to produce these molecules locally at elevated levels for extended periods. The proof of concept of gene therapies for arthritis has been exhaustively demonstrated in multiple laboratories and in numerous animal models. This review attempts to condense these studies and to discuss the relative benefits and limitations of the methods proposed and to discuss the challenges toward translating these technologies into clinical realities.

Abstract
Adeno-associated virus (AAV), a single-stranded DNA parvovirus, is emerging as one of the leading gene therapy vectors owing to its nonpathogenicity and low immunogenicity, stability and the potential to integrate site-specifically without known side-effects. A portfolio of recombinant AAV vector types has been developed with the aim of optimizing efficiency, specificity and thereby also the safety of in vitro and in vivo gene transfer. More and more information is now becoming available about the mechanism of AAV/host cell interaction improving the efficacy of recombinant AAV vector (rAAV) mediated gene delivery. This review summarizes the current knowledge of the infectious biology of AAV, provides an overview of the latest developments in the field of AAV vector technology and discusses remaining challenges.

Abstract
BACKGROUND The tumor necrosis factor (TNF)-alpha plays a central role in rheumatoid arthritis (RA) and current biotherapies targeting TNF-alpha have a major impact on RA treatment. The long-term safety concerns associated with the repetitive TNF blockade prompt optimization of therapeutic anti-TNF approaches. Since we recently demonstrated that intra-articular gene transfer using a recombinant adeno-associated virus serotype 5 (rAAV5) efficiently transduces arthritic joints, we evaluate its effect on collagen-induced arthritis (CIA) when encoding TNF antagonists. METHODS Recombinant AAV5 vectors encoding the human TNFRp55 extracellular domain fused to the Fc region of mice IgG1 (TR1) or a small molecular weight dimeric human TNFRp75 extracellular domain (TR2), under two different promoters, the CMV or a chimeric NF-kappaB-based promoter inducible by inflammation, were injected into mouse CIA joints. RESULTS Best protection against arthritis was obtained with the rAAV5 encoding the TR1, as reflected by delayed disease onset, decreased incidence and severity of joint damage. This effect was associated with a transient expression of the anti-TNF agent when expressed under a NF-kappaB-responsive promoter, only detectable during disease flare, while the antagonist expression was rapidly increased and stable when expressed from a CMV promoter. Importantly, using the intra-articular administration of the rAAV5-NF-kappaB-TR1 vector, we observed a striking correlation between local TR1 expression and inflammation. CONCLUSIONS These findings strongly support the feasibility of improving the safety of anti-TNF approaches for the treatment of arthritis by local rAAV5-mediated gene expression under an inflammation-responsive promoter, able to provide a limited, transient and therapeutically relevant expression of anti-TNF compounds.

Abstract
Sequestration of tumor necrosis factor-alpha (TNFalpha) by TNF-receptor immunoglobulin G (IgG)-Fc fusion proteins can limit heart failure progression in rodent models. In this study we directly injected an adeno-associated viruses (AAV)-2 construct encoding a human TNF receptor II IgG-Fc fusion protein (AAV-TNFRII-Fc) into healthy baboon hearts and assessed virally encoded gene expression and clinical response. Adult baboons received direct cardiac injections of AAV-TNFRII-Fc ( approximately 5 x 10(12) viral/genomes/baboon) or an equivalent dose of AAV-2 empty capsids, and were analyzed after 5 or 12 weeks. Viral genomes were restricted to the myocardium, and routine analyses (blood cell counts, clinical chemistries) remained unremarkable. Echocardiograms were unchanged but electrocardiograms revealed marked ST- and T-wave changes consistent with myocarditis only in baboons receiving AAV-TNFRII-Fc. TNFRII serum levels peaked at approximately 3 times the baseline levels at 1-2 weeks postinjection and subsequently declined to baseline levels. TNFRII-Fc protein and transcripts were detected in the heart at harvest. After AAV injection, anti-AAV-2 antibody levels increased in all baboons, while anti-TNFRII-Fc could not be detected. Baboons that received AAV-TNFRII-Fc developed myocardial infiltrates including CD8+ cells. Thus, a cellular immune response to cardiac delivery of AAV encoding foreign proteins may be an important consideration for AAV-based cardiac gene therapy.
