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

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 and IL13Ra2 (referred to as "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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Step #1 Inclusion Criteria:

  • Signed informed consent form
  • Male or females age ≥ 18 years.
  • Patients with newly diagnosed, EGFR-amplified, MGMT-unmethylated glioblastoma (as defined by WHO 2021 Classification for CNS Tumors, including that the tumor must be IDH wildtype). The tumor must also have histopathologic evidence of glioblastoma (i.e., presence of microvascular proliferation and/or necrosis).
  • Patients must have undergone maximal safe resection of the tumor as per routine cancer care. Patients who have had a biopsy only are not eligible.
  • Tumor tissue positive for wild-type EGFR amplification by Neogenomics Laboratories
  • Karnofsky Performance Status ≥ 60%
  • Patient scheduled to receive 60 Gy of radiotherapy. Either photon or proton therapy is acceptable.

Step #1 Exclusion Criteria:

  • Active hepatitis B or hepatitis C infection
  • Class III/IV cardiovascular disability according to the New York Heart Association Classification.
  • Tumors with enhancing disease involving the thalamus, brain stem or spinal cord.
  • Tumors with an MGMT promoter methylation result of hypermethylated, methylated, low positive methylated, or indeterminate.
  • Multifocal disease if ≥ 1 focus of tumor has not undergone maximal safe resection
  • Severe, active co-morbidity that, in the opinion of the physician-investigator, would preclude participation in this study.
  • History of allergy or hypersensitivity to study product excipients (human serum albumin, DMSO, and Dextran 40).
  • Active autoimmune disease requiring systemic immunosuppressive treatment equivalent to ≥ 10mg of prednisone. Patients with autoimmune neurologic diseases (such as MS) will be excluded.
  • Anticipated treatment plan that involves bevacizumab, any other systemic anti-neoplastic therapy, and/or tumor-treating fields as part of 1st line therapy.

Step #2 Inclusion Criteria:

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

Step #2 Exclusion Criteria:

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

Treatment and study plan

CART-EGFR-IL13Ra2 cells

Drug

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.

Rituximab or Rituximab biosimilar

Biological

375 mg/m2/day x 1 day

Fludarabine + Cyclophosphamide combination

Drug

Fludarabine: 30mg/m2/day x 3 days; Cyclophosphamide: 300mg/m2/day x 3 days

Primary outcomes

  1. Number of Subjects with treatment related adverse events using NCI Common Terminology Criteria for Adverse Events (CTCAE) V5.0

    Time frame: Up to 15 years following CART-EGFR-IL13Ra2 administration

    Type, frequency, severity, and attribution of adverse events

  2. Occurrence of treatment-limiting toxicities (TLTs)

    Time frame: 28 days post-CAR T cell administration

Secondary outcomes

  1. Proportion of enrolled subjects who receive study treatment as planned

    Time frame: 28 days following initial treatment with CART-EGFR-IL13Ra2 cells

    Evaluated based on the proportion of subjects who screen fail and those who receive any dose of CART-EGFR-IL13Ra2 cells.

  2. Proportion of eligible subjects who receive study treatment as planned

    Time frame: 28 days following initial treatment with CART-EGFR-IL13Ra2 cells

  3. Frequency of manufacturing failures

    Time frame: 3 months

    Proportion of subjects with CART-EGFR-IL13Ra2 products that fail to meet the product release criteria, out of the number of subjects in whom manufacturing was attempted.

    Proportion of subjects with CART-EGFR-IL13Ra2 products that fail to meet the assigned dose, out of the number of subjects in whom manufacturing was attempted.

  4. Progression-free Survival (PFS)

    Time frame: Up to 15 years following CART-EGFR-IL13Ra2 administration

    Per RANO 2.0 criteria

  5. Overall Survival (OS)

    Time frame: Up to 15 years following initial CART-EGFR-IL13Ra2 administration

    Time from initial study treatment to the date of death from any cause.

  6. Objective Response Rate (ORR)

    Time frame: Up to 12 months following CART-EGFR-IL13Ra2 administration

    Per RANO 2.0 criteria (in subjects with measurable disease at the time of study treatment); Proportion of subjects with confirmed CR and PR.

  7. Duration of response (DOR)

    Time frame: Up to 15 years following initial CART-EGFR-IL13Ra2 administration

    Per RANO 2.0 criteria (in subjects with measurable disease at the time of study treatment); Time from the date when a response of confirmed CR/PR is first met to the date of confirmed disease progression, death or receipt of alternative treatment other than CART-EGFR-IL13Ra2 retreatment.
