Long-term Follow-up of Subjects Treated With CARv3-TEAM-E T Cells

Study Purpose

This is a single site, non-randomized, open-label, long-term safety and efficacy follow-up Phase 1 study for subjects who have been treated with CARv3-TEAM-E T cells in clinical Study DF/HCC IRB #20-532 (the main study), that evaluated the safety and efficacy of CARv3-TEAM-E T cells in subjects with newly diagnosed or recurrent glioblastoma

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:

  • - Subjects will be asked to participate leading up to the last Study #20-532 visit.
Subjects meeting the following criteria are eligible for study participation:
  • - Provision of voluntary written informed consent by subject.
  • - CARv3-TEAM-E T cells were administered in DF/HCC IRB Study #20-532.
  • - Able to comply with study requirements.

Exclusion Criteria:

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.

NCT05024175
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

This is a single site, non-randomized, open-label, long-term safety and efficacy follow-up Phase 1 study for subjects who have been treated with CARv3-TEAM-E T cells in clinical Study DF/HCC IRB #20-532 (the main study), that evaluated the safety and efficacy of CARv3-TEAM-E T cells in subjects with newly diagnosed or recurrent glioblastoma. CARv3-TEAM-E drug product is defined as autologous T lymphocytes transduced with a CAR lentiviral vector encoding a chimeric antigen receptor targeting human EGFRvIII antigen and a T cell engaging antibody molecule (TEAM) targeting wildtype EGFR. CARv3-TEAM-E T cells are administered in subjects up to six times in main Study #20-532. No investigational treatment will be administered in this study. The United States Food and Drug Administration (FDA, 2018) recommend long-term follow-up for subjects treated with gene therapy drug products to monitor for selected adverse events (AEs) and the durability of clinical response. After the subjects in the parent study has been completed (24 months after CARv3-TEAM-E T cells infusion, or <24 months after CARv3-TEAM-E infusion if subject discontinues due to disease progression or any other reason), subjects will be asked to participate in a long-term follow-up study.
