In previous studies, we have demonstrated efficacy of AAVrh.10hARSA, an adeno-associated virus (AAV) serotype rh.10 vector coding for the human\n                    <jats:italic toggle=\"yes\">ARSA<\/jats:italic>\n                    gene to the CNS of a mouse model of the disease, and that catheter-based intraparenchymal administration of AAVrh.10hARSA to the CNS of nonhuman primates (NHPs) white matter results in widespread expression of ARSA. As a formal dose-escalating safety\/toxicology study, we assessed the safety of intraparenchymal delivery of AAVrh.10hARSA vector to 12 sites in the white matter of the CNS of NHPs at 2.85\u2009\u00d7\u200910\n                    <jats:sup>10<\/jats:sup>\n                    (total low dose, 2.4\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    genome copies [gc]\/site) and 1.5\u2009\u00d7\u200910\n                    <jats:sup>12<\/jats:sup>\n                    (total high dose, 1.3\u2009\u00d7\u200910\n                    <jats:sup>11<\/jats:sup>\n                    gc\/site) gc, compared to AAVrh.10Null (1.5\u2009\u00d7\u200910\n                    <jats:sup>12<\/jats:sup>\n                    gc total, 1.3\u2009\u00d7\u200910\n                    <jats:sup>11<\/jats:sup>\n                    gc\/site) as a vector control, and phosphate buffered saline for a sham surgical control. No significant adverse effects were observed in animals treated with low dose AAVrh.10hARSA. However, animals treated with the high dose AAVrh.10ARSA and the high dose Null vector had highly localized CNS abnormalities on magnetic resonance imaging scans at the sites of catheter infusions, and histopathology demonstrated that these sites were associated with infiltrates of T cells, B cells, microglial cells, and\/or macrophages. Although these findings had no clinical consequences, these safety data contribute to understanding the dose limits for CNS white matter direct intraparenchymal administration of AAVrh.10 vectors for treatment of CNS disorders.\n                  <\/jats:p>","DOI":"10.1089\/hum.2020.269","type":"journal-article","created":{"date-parts":[[2020,12,31]],"date-time":"2020-12-31T00:42:04Z","timestamp":1609375324000},"page":"563-580","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":43,"title":["Safety of Direct Intraparenchymal AAVrh.10-Mediated Central Nervous System Gene Therapy for Metachromatic Leukodystrophy"],"prefix":"10.1177","volume":"32","author":[{"given":"Jonathan B.","family":"Rosenberg","sequence":"first","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alvin","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bishnu P.","family":"De","sequence":"additional","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan P.","family":"Dyke","sequence":"additional","affiliation":[{"name":"Department of Radiology, Citigroup Biomedical Imaging Center, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Douglas J.","family":"Ballon","sequence":"additional","affiliation":[{"name":"Department of Radiology, Citigroup Biomedical Imaging Center, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastien","family":"Monette","sequence":"additional","affiliation":[{"name":"Center for Comparative Medicine and Pathology, Memorial Sloan Kettering Cancer Center and Weill Cornell Medicine, New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodolfo J.","family":"Ricart Arbona","sequence":"additional","affiliation":[{"name":"Center for Comparative Medicine and Pathology, Memorial Sloan Kettering Cancer Center and Weill Cornell Medicine, New York, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen M.","family":"Kaminsky","sequence":"additional","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald G.","family":"Crystal","sequence":"additional","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dolan","family":"Sondhi","sequence":"additional","affiliation":[{"name":"Department of Genetic Medicine, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,6,16]]},"reference":[{"key":"e_1_3_6_2_2","first-page":"3695","volume-title":"The Metabolic and Molecular Bases of Inherited Disease","author":"von Figura K","year":"2001","unstructured":"von Figura K, , Gieselmann V, , Jaeken J.
