Activated Autologous T Cells Against Glioma Cancer Stem Cell Antigens for Patients With Recurrent Glioblastoma

October 20, 2025 updated by: Jeremy Rudnick, M.D

A Phase I Trial of Activated Autologous T Cells Against Glioma Cancer Stem Cell Antigens for Patients With Recurrent Glioblastoma

The purpose of this study is to examine the use of activated T cells (ATCs) to assess the safety and tolerability of autologous activated T cells, as measured by the number of Grade 3 or higher toxicities, the number of serious adverse events, and treatment-related toxicities, according to National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) Version 5, to find the maximum tolerated dose. The secondary objectives include evaluating the rate of overall survival, rate of progression-free survival, health-related quality of life parameters, overall response rate, immune response, and tumor stem cell antigen expression.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Grade 3 or higher toxicities, number of serious adverse events, and the number of treatment-related toxicities to find the maximum tolerated dose
Time Frame: From start of study treatment until End of Study, an average of 2 months
Recorded and graded according to National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAEs) Version 5
From start of study treatment until End of Study, an average of 2 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Survival (OS)
Time Frame: From date of enrollment to date of death of any cause or withdrawal of consent, whichever came first. Assessed up to 3 years.
From date of enrollment to date of death of any cause or withdrawal of consent, whichever came first. Assessed up to 3 years.
Progression-Free Survival (PFS)
Time Frame: From start of study treatment, until confirmation of disease progression or withdrawal of consent, whichever came first. Assessed up to 3 years.
From start of study treatment, until confirmation of disease progression or withdrawal of consent, whichever came first. Assessed up to 3 years.
Health-related quality of life parameters
Time Frame: From baseline visit to End of Study, an average of 2 months
Measured by change in the Functional Assessment of Cancer Therapy - Brain (FACT-Br) survey score. The FACT-Br total score has a range of 0-200 and higher scores indicate better quality of life
From baseline visit to End of Study, an average of 2 months
Overall Response Rate (ORR)
Time Frame: From pre-study Brain MRI through study completion or withdrawal of consent, whichever came first. Assessed up to 3 years.
Percentage of patients showing either partial response or complete response, in patients with subtotal resection, will be measured using Magnetic Resonance Imaging (MRI) and Immunotherapy Response Assessment in Neuro-Oncology (iRANO) Response Criteria
From pre-study Brain MRI through study completion or withdrawal of consent, whichever came first. Assessed up to 3 years.
Immune Response
Time Frame: At Visit 1, Post-immunotherapy infusion follow-up Day 14, and Survival follow-up Month 2
Assessed by cytotoxic T cell activity in vitro pre- vs post-infusion.
At Visit 1, Post-immunotherapy infusion follow-up Day 14, and Survival follow-up Month 2
Tumor stem cell antigen expression
Time Frame: At Baseline visit and at time of recurrence. Assessed up to 3 years.
Assessed by quantitative PCR for expression of CD133, housekeeping genes, and tumor associated antigens (including HER2, TRP-2, gp100, MAGE-1, IL13Rα2, AIM-2).
At Baseline visit and at time of recurrence. Assessed up to 3 years.
