London, UK, September 21, 2016 / B3C newswire / -- Orchard Therapeutics announces that some of its academic collaborators will be presenting an update from ongoing clinical studies with autologous CD34+ haematopoietic stem cells transduced ex vivo with EFS lentiviral vector encoding for the human ADA gene for the treatment of patients diagnosed with severe combined immunodeficiency due to adenosine deaminase deficiency (ADA-SCID). The clinical data, being generated by University College London (“UCL”) / Great Ormond Street Hospital for Children NHS Foundation Trust (“GOSH”) and the University of California Los Angeles (“UCLA”), will be presented at the 17th biennial meeting of the European Society for Immunodeficiencies (“ESID”) in Barcelona, Spain (21–24 September 2016) and at the European Society of Gene and Cell Therapy (“ESGCT”) conference in Florence, Italy (18–21 October 2016).

The two clinical studies with ex-vivo EFS lentiviral-vector-based gene therapy have been designed as non-randomized studies to evaluate the safety and efficacy of treatment. Main endpoints include overall survival, event-free survival, immune system reconstitution, ADA enzyme activity and safety parameters.

Clinical data highlights

-       As of September 2016, a total of 39 patients with ADA-SCID have been treated at GOSH and UCLA, with a follow-up of 1–55 months
-       The data presented at ESID and ESGCT are based on an analysis of clinical data from 32 patients
-       All patients have survived (100% overall survival) and 31 out of 32 patients show immune reconstitution, with so far a favourable safety profile

At ESID, Professor Bobby Gaspar and Dr Claire Booth, both from UCL, will present on 21 and 23 September 2016, respectively. Further data will be presented by Professor Donald Kohn, from UCLA, at ESGCT on 20 October 2016.

About ADA-SCID
ADA-SCID is a rare inherited disorder of the immune system. The incidence of ADA-SCID is currently estimated between 1 in every 375,000–660,000 live births. ADA-SCID is caused by mutations in the gene encoding for the adenosine deaminase enzyme, which result in a severe deficiency in white blood cells and life-threatening infections.
