Orchard Therapeutics Announces Global License Agreements for Stable Cell Line Technology from GSK

July 15, 2020

Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, today announced that the company has entered into two worldwide royalty-bearing license agreements with GlaxoSmithKline plc (GSK) (LSE/NYSE: GSK) for use of their proprietary lentiviral stable cell line technology (LV-SCLT) for Orchard’s investigational hematopoietic stem cell gene therapies for Wiskott Aldrich syndrome (OTL-103 for WAS) and transfusion-dependent beta thalassemia (OTL-300 for TDT).

The LV-SCLT permanently and stably enables all the lentiviral vector components to be introduced into a cell line in one step. Selection and expansion of a resulting clonal producer line in either suspension or adherent culture can deliver consistent levels of high titer lentiviral production comparable to those seen using conventional methods. An overview of this technology, co-authored by Orchard and GSK scientists, was presented at the European Society of Gene & Cell Therapy (ESGCT) Annual Congress in October 2019 using work done in the OTL-300 program for TDT. Under the licenses, GSK has granted patents and pending patent applications related to its LV-SCLT.
