Abstract
Late infantile Batten disease (CLN2 disease) is an autosomal recessive, neurodegenerative lysosomal storage disease caused by mutations in the CLN2 gene encoding tripeptidyl peptidase 1 (TPP1). We tested intraparenchymal delivery of AAVrh.10hCLN2, a nonhuman serotype rh.10 adeno-associated virus vector encoding human CLN2, in a nonrandomized trial consisting of two arms assessed over 18 months: AAVrh.10hCLN2-treated cohort of 8 children with mild to moderate disease and an untreated, Weill Cornell natural history cohort consisting of 12 children. The treated cohort was also compared to an untreated European natural history cohort of CLN2 disease. The vector was administered through six burr holes directly to 12 sites in the brain without immunosuppression. In an additional safety assessment under a separate protocol, five children with severe CLN2 disease were treated with AAVrh.10hCLN2. The therapy was associated with a variety of expected adverse events, none causing long-term disability. Induction of systemic anti-AAVrh.10 immunity was mild. After therapy, the treated cohort had a 1.3- to 2.6-fold increase in cerebral spinal fluid TPP1. There was a slower loss of gray matter volume in four of seven children by MRI and a 42.4 and 47.5% reduction in the rate of decline of motor and language function, compared to Weill Cornell natural history cohort (P < 0.04) and European natural history cohort (P < 0.0001), respectively. Intraparenchymal brain administration of AAVrh.10hCLN2 slowed the progression of disease in children with CLN2 disease. However, improvements in vector design and delivery strategies will be necessary to halt disease progression using gene therapy.

Abstract
The development of a drug product requires rigorous methods of characterization and quality control to assure drug potency. Gene therapy products, a relatively new strategy for drug design with very few licensed examples, represent a unique challenge for the measure of potency. Unlike traditional drugs, potency for a gene therapeutic is a tally of the measures of multiple steps, including infectivity, transcription, translation, protein modifications, proper localization of the protein product, and protein function. This is particularly challenging for products based on the adeno-associated virus (AAV) platform, which has poor in vitro infectivity, limiting the sensitivity and thus the usefulness of cell-based assays. A rigorous in vivo assay has been established that separately evaluates infection, transcription, and resulting protein levels with specifications for each based on real time polymerase chain reaction (DNA and RNA) and standard protein assays. For an acceptance criterion, an administered vector must have vector DNA, transgene mRNA, and transgene expressed protein each concurrently meet individual specifications or the production lot fails. Using the AAVrh.10 serotype as a model vector and three different transgenes as examples, the assay is based on intravenous administration of the vector to male mice. At 2 weeks, the harvested liver is homogenized and assessed for vector genome levels (to assess for vector delivery), mRNA (to assess vector infectivity and transcription), and protein in the liver or serum (to assess protein expression). For all AAV vectors, the assay is robust and reproducible: vector DNA (linearity 102-109 copies, coefficient of variation) intra-assay <0.8%, inter-assay <0.5%; mRNA intra-assay <3.3%, inter-assay <3.4%. The reproducibility of the assay for transgene expressed protein is product specific. This in vivo potency assay is a strategy for characterization and a quantitative lot release test, providing a path forward to meet regulatory drug requirements for any AAV gene therapy vectors.

Abstract
Cardiac gene therapy offers a strategy to treat diffuse coronary artery disease (CAD), a disorder with no therapeutic options. The use of genes to revascularize the ischemic myocardium has been the focus of two decades of preclinical research with a variety of angiogenic mediators, including vascular endothelial growth factor, fibroblast growth factor, hepatocyte growth factor, and others encoded by DNA plasmids or adenovirus vectors. The multifaceted challenge for developing efficient induction of collateral vessels in the ischemic heart requires a choice for route of delivery, dosing level, a relevant animal model, duration of treatment, and assessment of phenotype for efficacy. Overall, studies of gene therapy for ischemia in experimental models are very encouraging, with clear evidence of safety and efficacy, strongly supporting the concept that gene therapy to induce angiogenesis is a viable therapeutic approach for CAD. Clinical studies of cardiac gene therapy with angiogenic factors have added substantially to the evidence for efficacy, but definitive studies have not yet led to commercial approval. This review provides the general concepts for angiogenesis-based therapeutic approaches for diffuse CAD and summarizes the results from key studies in the field with recommendations for refinement to a successful product design and evaluation.
