Study Endpoints

Primary Endpoints

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):

Treatment Arms

ArmTypeDescription
GCAR1EXPERIMENTALThis 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.

Interventions

NameTypeDescription
GCAR1BIOLOGICALGCAR1 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.

Frequently asked questions about GCAR1

What is GCAR1 used for?

GCAR1 is an investigational chimeric antigen receptor (CAR) T cell therapy being developed for the treatment of sarcoma, specifically alveolar soft part sarcoma (ASPS). It is currently in Phase 1 clinical development and is being studied in patients with relapsed disease.

What does GCAR1 target?

GCAR1 is a monoclonal antibody-based CAR T cell therapy. While the specific molecular target is not disclosed in available information, it is designed to recognize and attack sarcoma cells. The therapy is being evaluated in a biomarker-selected patient population, indicating that target expression is a criterion for enrollment.

Who is developing GCAR1?

GCAR1 is being developed by Precision BioSciences, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol DTIL. The company is conducting a Phase 1 clinical trial of GCAR1 in patients with relapsed alveolar soft part sarcoma.

What phase is GCAR1 in?

GCAR1 is in Phase 1 clinical development. The ongoing trial is an early Phase 1 study, currently active but not recruiting participants. As an investigational therapy, GCAR1 has not yet been approved by regulatory authorities and remains in clinical testing.

What clinical trials is GCAR1 in?

GCAR1 is being evaluated in a single clinical trial registered as NCT06813417, titled 'CAR T Therapy With GCAR1 for Relapsed Alveolar Soft Part Sarcoma.' This early Phase 1 study is active but not recruiting, with an enrollment of one participant, and is being conducted in Canada.

Is GCAR1 the same as other CAR T therapies?

GCAR1 is a CAR T cell therapy, but it is a distinct investigational product developed by Precision BioSciences. It is being studied specifically for alveolar soft part sarcoma, a rare soft tissue sarcoma. No alternative names for GCAR1 have been disclosed in available information.
