CAR T Therapy With GCAR1 for Relapsed Alveolar Soft Part Sarcoma
Sponsor: University of Calgary
Summary
A single patient study to determine whether GCAR1 is safe and effective for re-treatment of alveolar soft part sarcoma (ASPS) with GPNMB surface expression that has relapsed and is not responding to usual treatment.
Official title: An Open Label Individual Patient Dose Escalation Study Investigating the Safety and Efficacy of Retreatment With GCAR1 in a Patient With Multiply Relapsed Alveolar Soft Part Sarcoma

GCAR1
GCAR1 is a patient-specific cell therapy product containing a mixture of autologous lymphocytes transduced with a lentiviral vector encoding a chimeric antigen receptor (CAR) targeting GPNMB. The CAR comprises a single-chain variable fragment (scFv) binding domain derived from a fully human GPNMB-specific monoclonal antibody (CDX-011), a CD8 hinge and transmembrane domain, and the CD137 (4-1BB) and CD3 zeta chain intracellular signaling domains. Following infusion, the autologous GPNMB CAR T-cells expressing the genetically engineered anti-GPNMB CAR enable the specific targeting of GPNMB-expressing cells. Upon binding to GPNMB-expressing cells, the CAR transmits T cell activation signals that promote the elimination of target cells through CAR T cell degranulation and the release of cytotoxic molecules. The cellular signal also facilitates CAR T cell proliferation and persistence that may enable prolonged disease control through immunosurveillance3.
