GPC2 CAR T Cells for Relapsed or Refractory Neuroblastoma

Study Purpose

This is a first in human dose escalation trial to determine the safety of administering GPC2 CAR T cells in patients with advanced neuroblastoma.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Signed Informed Consent Form. 2. ≥ 1 year of age. 3. Disease status. 1. Patients must have high-risk neuroblastoma according to Children's Oncology Group risk classification at the time of study enrollment. 2. Histologically confirmed diagnosis of neuroblastoma that is recurrent/relapsed/persistent according to International Neuroblastoma Response Criteria. 3. Patients must have evaluable or measurable disease at enrollment. 4. Adequate organ function. 5. Adequate performance status defined as Lanksy or Karnofsky performance score ≥60. 6. Subjects of reproductive potential must agree to use acceptable birth control methods.

Exclusion Criteria:

1. Patients with active hepatitis B or active hepatitis C. 2. Patients with HIV infection. 3. Patients with uncontrolled active infection. 4. Patients with primary or acquired immunodeficiency disorder. 5. Concurrent use of systemic steroids or immunosuppression at the time of cell infusion or cell collection, or a condition, in the treating physician's opinion, that is likely to require steroid therapy or immunosuppression during collection or after infusion. Steroids for disease treatment at times other than cell collection or at the time of infusion are permitted. Use of physiologic replacement hydrocortisone or inhaled steroids is permitted as well. 6. Patients with actively progressing Central Nervous System metastases, including parenchymal or leptomeningeal involvement. 7. Active medical disorder that, in the opinion of the investigator, would substantially increase. the risk of uncontrollable Cytokine Release Syndrome and/or neurotoxicity. 8. Patients with congestive heart failure (as defined by New York Heart Association Functional Classification III or IV), unstable angina, serious uncontrolled cardiac arrhythmia, a myocardial infarction within 6 months prior to study entry or a history of myocarditis. 9. Patients who have received any live vaccines within 30 days prior to enrollment. 10. Pregnant or nursing (lactating) women.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05650749
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Despite the use of intensive multimodal chemoradiotherapy, surgery, autologous stem cell transplant and disialoganglioside antigen (GD2)-targeted immunotherapy for the treatment of patients with high-risk neuroblastoma, approximately 60% of children still die from this disease and survivors suffer lifelong treatment related comorbidities. For patients who suffer a relapse after receiving therapy with standard of care multimodality treatment, there are no known curative options. Glypican 2 (GPC2) is highly expressed on the plasma membrane of most high-risk neuroblastomas, is further enriched in the tumor stem cell compartment, but is not expressed at significant levels on normal tissues, making it an ideal target for immune directed therapies. To therapeutically leverage GPC2's differential expression, a GPC2-directed CAR T cell therapy that potently inhibits the growth of neuroblastoma patient-derived xenografts has been developed. This investigation will be a single institution, open-label first in human, dose escalation and expansion study designed to assess the safety, tolerability, and manufacturing feasibility of GPC2 CAR T cells.

Arms & Interventions

Arms

Experimental: Dose Escalation Arm

The dose escalation arm will determine the maximum tolerated dose of GPC2 CAR T cells using a standard 3+3 trial design.

Experimental: Dose Expansion Arm

If at least one dose from the dose expansion arm is determined to be safe, additional patients will be enrolled to the dose expansion arm to preliminarily evaluate the rate of response to GPC2 CAR T cells and further characterize the safety profile of GPC2 CAR T cells.

Interventions

Biological: - GPC2 CAR T cells

The GPC2 CAR T investigational product is comprised of autologous human T cells that have been genetically modified to express a GPC2-targeting chimeric antigen receptor (CAR) transgene.
