IL-8 Receptor Modified Patient-Derived Activated CD70 CAR T Cell Therapy in Adults With Brain Metastases

Who can take part

• Histological confirmation of primary cancers
• Histologic confirmation of CD70 on primary tumor, lymph node, or BM biopsy CD70-positive tumor expression confirmed by the investigational CD70 IHC assay defined as CD70 immunoreactivity in ≥ 5% of tumor cells at any staining intensity
• At least one recurrent or progressive metastatic lesion or new metastatic lesion(s)
• KPS ≥ 70
• 18 years or older
• Adequate bone marrow and organ function as defined below:; CBC with differential with adequate bone marrow function as defined below:; Absolute neutrophil count (ANC) ≥ 1000 cells/mm3; Platelet count ≥ 75,000 cells/mm3; Hemoglobin ≥ 9 g/dl. (use of transfusion or other intervention to achieve Hgb ≥ 9 g/dl is acceptable.)
• Adequate renal function as defined below:; BUN ≤ 25 mg/dl; Creatinine ≤ 1.7 mg/dl
• Adequate hepatic function as defined below:; Bilirubin ≤ 2.0 mg/dl; ALT ≤ 5 times institutional upper limits of normal for age; AST ≤ 5 times institutional upper limits of normal for age
• A diagnostic contrast-enhanced brain MRI must be performed within 28 days prior to study enrollment
• For females of childbearing potential, a negative serum pregnancy test at enrollment
• Women of childbearing potential (WOCBP) must be willing to use an acceptable contraceptive method to avoid pregnancy throughout the study and for at least 24 weeks after the last dose of study drug
• Males with female partners of childbearing potential must agree to practice adequate contraceptive methods throughout the study and should avoid conceiving children for 24 weeks following the last dose of the study drug
• Ability of the patient to understand and willingness to sign an IRB approved written informed consent document
• Steroid dose equivalent to dexamethasone dose of ≤ 6mg daily at the time of enrollment
• Patients treated on any other investigational therapy must discontinue that treatment prior to study entry

Who cannot take part

• Participant has ongoing toxicity ≥ grade 2 per the CTCAE version 5.0 considered clinically significant and in the opinion of the investigator, attributable to prior antineoplastic therapies
• Participant has received any chemotherapy or other immunotherapy within 14 days prior to the first dose of study intervention
• Known immunosuppressive disease or human immunodeficiency virus (HIV) infection; Rationale: The need to exclude patients with an immunosuppressive disease or human immunodeficiency virus infection is necessary because the management of potential toxicities from the study drug may involve treatment that is significantly immunosuppressive
• Severe, active co-morbidity, defined as follows:; Unstable angina and/or congestive heart failure requiring hospitalization; Transmural myocardial infarction within the last 6 months; Acute bacterial or fungal infection requiring intravenous antibiotics; Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization; Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects; Patients with an autoimmune disease requiring medical management with immunosuppressants; Major medical illnesses or psychiatric impairments that, in the investigator's opinion, will prevent administration or completion of protocol therapy
• Pregnant or lactating women, due to possible adverse effects on the developing fetus or infant
