About this study
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
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.
Read the 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).

What participants receive

GCAR1Biological
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.
| Study group | Role | What they receive |
|---|---|---|
| GCAR1 | Experimental | This is an intrapatient two-dose escalation study. The patient will receive two separate intravenous infusions of cryopreserved, autologous GCAR1, with at least three months (+/- 30 days) between infusions. Both infusions will be preceded by standard lymphodepleting chemotherapy (Fludarabine 40 mg/m2 x 3 days, cyclophosphamide 600 mg/m2 x 2 days) . Dose 1 will be 5.0E6 CAR+ T cells/kg patient body weight, Dose 2 will be 2.5E7 CAR+ T cells/kg patient body weight. Infusions will be intravenous, single infusions. Receives: Biological: GCAR1 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Treatment Response
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):
Measured: 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.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing GCAR1 in people with Sarcoma and Alveolar Soft Part Sarcoma (ASPS), run by University of Calgary at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 10 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Treatment Response (time frame: 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.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Apr 2025.
