Item The Access Technology Program of the Indiana Clinical Translational Sciences Institute (CTSI): A model to facilitate access to cutting-edge technologies across a state(Cambridge, 2021) Orschell, Christie M.; Skaar, Todd C.; DeFord, Melanie E.; Ybe, Joel; Driscol, Julie; Drury, Christine; Reeves, Lilith; Willis, Monte S.; Reiter, Jill L.; York, Jenna; Orr, Rob; McClintick, Jeanette N.; Sors, Thomas G.; Hunt, Joe; Cornetta, Kenneth; Shekhar, Anantha; Medicine, School of MedicineIntroduction: Access to cutting-edge technologies is essential for investigators to advance translational research. The Indiana Clinical and Translational Sciences Institute (CTSI) spans three major and preeminent universities, four large academic campuses across the state of Indiana, and is mandate to provide best practices to a whole state. Methods: To address the need to facilitate the availability of innovative technologies to its investigators, the Indiana CTSI implemented the Access Technology Program (ATP). The activities of the ATP, or any program of the Indiana CTSI, are challenged to connect technologies and investigators on the multiple Indiana CTSI campuses by the geographical distances between campuses (1–4 hr driving time). Results: Herein, we describe the initiatives developed by the ATP to increase the availability of state-of-the-art technologies to its investigators on all Indiana CTSI campuses, and the methods developed by the ATP to bridge the distance between campuses, technologies, and investigators for the advancement of clinical translational research. Conclusions: The methods and practices described in this publication may inform other approaches to enhance translational research, dissemination, and usage of innovative technologies by translational investigators, especially when distance or multi-campus cultural differences are factors to efficient application.Item Autologous Ex Vivo Lentiviral Gene Therapy for Adenosine Deaminase Deficiency(Massachusetts Medical Society, 2021-05-27) Kohn, Donald B.; Booth, Claire; Shaw, Kit L.; Xu-Bayford, Jinhua; Garabedian, Elizabeth; Trevisan, Valentina; Carbonaro-Sarracino, Denise A.; Soni, Kajal; Terrazas, Dayna; Snell, Katie; Ikeda, Alan; Leon-Rico, Diego; Moore, Theodore B.; Buckland, Karen F.; Shah, Ami J.; Gilmour, Kimberly C.; De Oliveira, Satiro; Rivat, Christine; Crooks, Gay M.; Izotova, Natalia; Tse, John; Adams, Stuart; Shupien, Sally; Ricketts, Hilory; Davila, Alejandra; Uzowuru, Chilenwa; Icreverzi, Amalia; Barman, Provaboti; Fernandez, Beatriz Campo; Hollis, Roger P.; Coronel, Maritess; Yu, Allen; Chun, Krista M.; Casas, Christian E.; Zhang, Ruixue; Arduini, Serena; Lynn, Frances; Kudari, Mahesh; Spezzi, Andrea; Zahn, Marco; Heimke, Rene; Labik, Ivan; Parrott, Roberta; Buckley, Rebecca H.; Reeves, Lilith; Cornetta, Kenneth; Sokolic, Robert; Hershfield, Michael; Schmidt, Manfred; Candotti, Fabio; Malech, Harry L.; Thrasher, Adrian J.; Gaspar, H. Bobby; Medicine, School of MedicineBackground: Severe combined immunodeficiency due to adenosine deaminase (ADA) deficiency (ADA-SCID) is a rare and life-threatening primary immunodeficiency. Methods: We treated 50 patients with ADA-SCID (30 in the United States and 20 in the United Kingdom) with an investigational gene therapy composed of autologous CD34+ hematopoietic stem and progenitor cells (HSPCs) transduced ex vivo with a self-inactivating lentiviral vector encoding human ADA. Data from the two U.S. studies (in which fresh and cryopreserved formulations were used) at 24 months of follow-up were analyzed alongside data from the U.K. study (in which a fresh formulation was used) at 36 months of follow-up. Results: Overall survival was 100% in all studies up to 24 and 36 months. Event-free survival (in the absence of reinitiation of enzyme-replacement therapy or rescue allogeneic hematopoietic stem-cell transplantation) was 97% (U.S. studies) and 100% (U.K. study) at 12 months; 97% and 95%, respectively, at 24 months; and 95% (U.K. study) at 36 months. Engraftment of genetically modified HSPCs persisted in 29 of 30 patients in the U.S. studies and in 19 of 20 patients in the U.K. study. Patients had sustained metabolic detoxification and normalization of ADA activity levels. Immune reconstitution was robust, with 90% of the patients in the U.S. studies and 100% of those in the U.K. study discontinuing immunoglobulin-replacement therapy by 24 months and 36 months, respectively. No evidence of monoclonal expansion, leukoproliferative complications, or emergence of replication-competent lentivirus was noted, and no events of autoimmunity or graft-versus-host disease occurred. Most adverse events were of low grade. Conclusions: Treatment of ADA-SCID with ex vivo lentiviral HSPC gene therapy resulted in high overall and event-free survival with sustained ADA expression, metabolic correction, and functional immune reconstitution.
