Inclusion Criteria:
-Safety Run In Arm and ARM 1: Recurrent GBM, EGFRvIII mutant.
- - Participants must have histologically confirmed recurrent GBM or molecular features
of GBM with presence of EGFRvIII mutation within 30 days of consent.
MGMT
methylated, unmethylated, or unknown is allowed.
- - Participants must be at first progression or recurrence and have at least received
prior radiation.
Prior temozolomide is not required if the participant is MGMT
unmethylated.
Participants must be 4 weeks from prior alkylating therapy or immunotherapy and ≥ 5
half-lives from another investigational agent. No washout is required from radiation
since participants will need histological confirmation of recurrence to participate.
- - ARM 2: Newly Diagnosed GBM, EGFRvIII mutant.
- - Participants must have histologically confirmed newly diagnosed GBM with
presence of EGFRvIII mutation and their tumors must be MGMT unmethylated.
- - Treatment planned with involved field radiation alone without concomitant or
sequential temozolomide.
- - ARM 3: Recurrent GBM, EGFRvIII negative (will only open once safety is confirmed in
Arms 1 and 2)
- Participants must have histologically confirmed recurrent GBM with absence of
EGFRvIII mutation within 30 days of consent but with EGFR amplification.
- - Participants must be at first recurrence and have at least received prior
radiation.
Prior temozolomide is not required if the participant is MGMT
unmethylated. Participants must be 4 weeks from prior alkylating therapy or
immunotherapy and ≥ 5 half-lives from another investigational agent. No washout
is required from radiation since participants will need histological
confirmation of recurrence to participate.
- - ALL ARMS:
- Participants must have measurable disease, defined as at least one lesion ≥10
mm (≥1 cm) with MRI.
Patients cannot have posterior fossa or intramedullary
spine-only disease. Leptomeningeal disease is allowed anywhere in the
neuroaxis. See Section 11 (Measurement of Effect) for the evaluation of
measurable disease.
- - Resolution of AEs from any prior systemic anticancer therapy or radiotherapy to
Grade 1 or baseline (except Grade 2 alopecia and Grade 2 sensory neuropathy)
- Medically able and willing to undergo placement of an Ommaya reservoir.
- - Steroid dose anticipated to be ≤ 4 mg of dexamethasone a day or equivalent at
time of first CAR-v3-TEAM-E infusion.
- - Karnofsky ≥60% (see Appendix A).
- - Must be able to undergo an MRI with contrast.
- - Life expectancy of greater than 3 months.
- - Participants must have adequate organ and marrow function as defined below:
- absolute neutrophil count ≥1,000/mcL.
- - total bilirubin ≤ institutional upper limit of normal (ULN)
- AST(SGOT)/ALT(SGPT) ≤3 × institutional ULN.
- - creatinine ≤ institutional ULN OR.
- - glomerular filtration rate (GFR) ≥60 mL/min/1.73 m2.
For patients with Gilbert's syndrome, total bilirubin can be ≤ 3xULN.
- - Participant has no prior history of malignancy, unless the subject has been free of
the disease for ≥5 years with the exception of the following noninvasive
malignancies:
- Basal cell carcinoma of the skin.
- - Squamous cell carcinoma of the skin.
- - Carcinoma in situ of the cervix.
- - Carcinoma in situ of the breast.
- - Incidental histologic finding of prostate cancer (T1a or T1b) or prostate
cancer that is curative.
- - Left ventricular ejection fraction >50% as determined by TTE.
- - The effects of CARv3-TEAM-E on the developing human fetus are unknown.
For this
reason, women of child-bearing potential and men must agree to use adequate
contraception (hormonal or barrier method of birth control; abstinence) prior to
study entry and for the duration of study participation. Should a woman become
pregnant or suspect she is pregnant while she or her partner is participating in
this study, she should inform her treating physician immediately. Men treated or
enrolled on this protocol must also agree to use adequate contraception prior to the
study, for the duration of study participation, and 4 months after completion of
CARv3-TEAM-E administration.
- - Ability to understand and the willingness to sign a written informed consent
document.
Exclusion Criteria:
- - Intraparenchymal posterior fossa disease.
- - Intramedullary spinal disease as the only site of disease.
- - Prior EGFRvIII targeted therapies.
- - Treatment with an any prior gene-therapy or gene-modified cellular therapy.
- - Ongoing treatment with chronic immunosuppressants (e.g., cyclosporine or systemic
steroids above physiologic dosing).
Intermittent topical, inhaled, or intranasal
corticosteroids are allowed.
- - Participants who have not recovered from adverse events due to prior anti-cancer
therapy (i.e., have residual toxicities > Grade 1) with the exception of alopecia.
- - Participants who are receiving any other investigational agents.
- - History of allergic reactions attributed to compounds of similar chemical or
biologic composition to CARv3-TEAM-E (ex.
cetuximab).
- - Participants with uncontrolled intercurrent illness.
- - Human immunodeficiency virus (HIV)-infected participants are not eligible.
- - Participants with evidence of chronic hepatitis B virus (HBV) infection or active
hepatitis C virus (HCV) infection are not eligible.
- - Participants with psychiatric illness/social situations that would limit compliance
with study requirements.
- - Pregnant women are excluded from this study because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of the
mother with CARv3-TEAM-E , breastfeeding should be discontinued if the mother is
treated with CARv3-TEAM-E.
- - For Arm 2, prior to CARv3-TEAM-E Infusion, the following criteria should be
confirmed in addition to the relevant criteria above:
- Participants must have completed 75% of the planned 6 weeks of involved field
radiation without temozolomide.
- - Tumor location and size criteria as in 3.1.
7 above.
- - Prior cancer directed therapy other than radiation is not allowed.
