Brief 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.
Detailed description
CLIC-YYC-GPNMB-04 is an Open Label Individual Patient (OLIP)/Single Patient Study (SPS) developed according to the Health Canada template and guidelines released in 2019 for studies to access therapies not otherwise available to patients, in the situation where there are no options of treatment or cure remaining. The patient under consideration for CLIC-YYC-GPNMB-04 has refractory, progressive metastatic alveolar soft part sarcoma (ASPS). There are no standard therapies for relapsed ASPS known to provide potential for cure, and there are no clinical trials available in Canada for consideration. We propose to re-treat the patient with GCAR1, a patient-specific cell therapy product containing a mixture of autologous lymphocytes transduced with a lentiviral vector containing a chimeric antigen receptor (CAR) that enables the specific targeting towards tumor cells expressing the cell surface protein glycoprotein non-metastatic B (GPNMB). The patient was previously treated with GCAR1 under CLIC-YYC-GPNMB-01 (c#276646).
Interventions
BIOLOGICALGCAR1
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment Response | Diagnostic imaging (CT and/or MRI) will be performed at baseline (pre-treatment) and then subsequently at 4-6 weeks after GCAR1 infusion, and at 3 months, 6 months, 9 months and 1 year after last infusion to evaluate response to therapy. | The overall response assessment considers the response of the target and non-target lesions and development of new lesions. Response Classification of Target Lesions, CNS lesions and Non-Target Lesions * Complete response (CR): * Partial response (PR): * Progressive disease (PD): * Stable disease (SD): |
