CART-EGFR-IL13Ra2 in Newly Diagnosed GBM Following Initial Radiotherapy

Study Purpose

This is an open-label phase 1 study to assess the safety, feasibility, pharmacokinetics and preliminary efficacy of autologous T cells co-expressing two CARs targeting the cryptic EGFR epitope 806 a nd I L13Ra2 ( referred t o a s " CART-EGFR-IL13Ra2 cells") in patients with newly diagnosed, EGFR-amplified, MGMT-unmethylated glioblastoma, without evidence of disease recurrence/progression following completion of initial radiotherapy.

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.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Patient completed full course of radiotherapy to 60 Gy. 2. No overt evidence of disease recurrence/progression post-radiotherapy confirmed by RANO 2.0 criteria. 3. Karnofsky Performance Status ≥ 60% 4. Adequate organ function defined as: 1. Serum creatinine ≤ 1.5x ULN or estimated creatinine clearance ≥ 30 mL/min and not on dialysis. 2. ALT/AST ≤ 3 x ILN. 3. Total bilirubin ≤ 2.0 mg/dl, except for patients in whom hyperbilirubinemia is attributed to Gilbert's syndrome (≤ 3.0 mg/Dl) 4. Left Ventricular Ejection Fraction (LVEF) ≥ 45% confirmed by ECHO/MUGA. 5. Must have minimum level of pulmonary reserve defined as > 92% on room air.

Exclusion Criteria:

1. Any active, uncontrolled infection. 2. Severe, active co-morbidity that, in the opinion of the physician-investigator, would preclude participation in this study. 3. Clinical or neurological decline related to disease and/or radiotherapy that, in the opinion of the physician-investigator, would preclude participation in this study. 4. Pregnant or nursing (lactating) patients. Participants of reproductive potential must agree to use acceptable birth control methods, as described in Protocol Section 4.3. 5. Receipt of prior bevacizumab therapy for their newly diagnosed glioblastoma. 6. Receipt of temozolomide for their newly diagnosed glioblastoma. 7. Anticipated post-radiotherapy maintenance treatment that includes tumor treating fields, bevacizumab, or any other anti-neoplastic therapies. 8. Enrollment in any other clinical trial for the treatment of their newly diagnosed glioblastoma.

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.	NCT06973096
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.	Phase 1

Arms & Interventions

Arms

Experimental: Dose Level 1

Dose Level 1 (DL1): will receive single fixed dose of 2.5x10^7 CART-EGFR-IL13Ra2 cells via intracerebroventricular (ICV) injection on Day 0.

Experimental: Dose Level -1 (DL-1)

Dose Level-1 (DL-1): will receive single fixed dose of 1x10^7 CART-EGFR-IL13Ra2 cells via intracerebroventricular (ICV) injection on Day 0. This dose level will only be explored if there are at least two TLTs observed at DL1.

Interventions

Drug: - CART-EGFR-IL13Ra2 cells

autologous T cells transduced with a bicistronic lentiviral vector containing a murine scFv targeting EGFR epitope 806 and a humanized scFv targeting IL13Ra2; both scFvs are fused to the 4-1BB and CD3ζ signaling domains.
